Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a data recording / reproducing apparatus, and more particularly, to a data recording / reproducing apparatus preferably applied to a video server system used in a broadcasting company, particularly a broadcasting station of a general broadcasting company.
[0002]
[Prior art]
Broadcasters store and manage video and audio data (hereinafter referred to as “material data”) of various broadcast materials produced inside and outside the station, and accurately according to playlists and program schedules at a set time. Must be broadcast (sent). In particular, a general broadcasting company called “commercial broadcasting” has to deal with a large amount of commercial material in addition to the above-mentioned data. Therefore, the complexity of the material management and transmission control cannot be denied.
[0003]
Conventionally, the management of material data in broadcasting stations has been exclusively based on magnetic tape media. In other words, the material data to be sent is recorded on a cassette-shaped magnetic tape medium, which is set on a sending device and sent while switching according to a playlist or program organization table. Since it is impossible, for example, cueing of specific material data cannot be performed efficiently, and there is a drawback that it is extremely difficult to manage individual material data recorded on a magnetic tape.
[0004]
Therefore, a video server system for a broadcasting station in which a large number of hard disks, which are storage media that can be randomly accessed, are connected to construct an array-shaped mass storage device, and a large amount of material data is stored in the storage device. Is provided.
[0005]
According to this, the video server system is controlled from the console (terminal) to efficiently perform storage of material data (so-called filing), reproduction confirmation of stored data (so-called preview), and transmission control of material data. Can do.
[0006]
There are two types of previews: a mother preview that checks the image quality and sound quality of each piece of material data and the suitability of trim values, and an on-air preview that checks a playlist and a program organization table. Hereinafter, the simple preview refers to the former mother preview.
[0007]
The trim value adjustment (or trim width adjustment or trimming adjustment; hereinafter simply referred to as “trim adjustment”) includes how many frames (described later) are included before and after the material data when it is transmitted (broadcast). Or how many frames before and after the material data are to be cut.
[0008]
The trim adjustment will be described in detail. As shown in FIG. 20A, the material data includes a main part corresponding to the reproduction length of the material data (generally expressed in units of time; hereinafter referred to as “DUR”), and the main part. And a predetermined number of extra cuts recorded before and after. SOM points that are actually broadcasted by recording 15 frames before and after the SOM (Start Of Message) point and EOM (End Of Message) point that are determined at the stage of producing the CM when the material is stored on the server It is a mechanism that can be adjusted in the width of 10 frames back and forth.
[0009]
The initial value of trim adjustment is “0”. When the trim value is 0, as shown in FIG. 20B, only the main part is designated as a transmission target (in the figure, Pa: transmission start point, Pb: transmission end point). That is, in this case, the cut-off is ignored, but if the trim value is “+ i” (where i is an integer greater than 0; the same applies hereinafter), as shown in FIG. From the TC (Time Code) of the SOM point, the position (Pa) of + i frame is transmitted as the SOM point. Since the DUR is fixed and determined, the EOM point is automatically shifted to the position (Pb) of the + i frame.
[0010]
Alternatively, when the trim value is set to “−i”, as shown in FIG. 20D, transmission is performed with the position (Pa) of the −i frame from the TC of the original SOM point of the material data as the SOM point. Since the DUR is fixed and determined, the EOM point is automatically shifted to the position (Pb) of the -i frame.
[0011]
As described above, the preview operation includes the operation of evaluating the suitability of the trim value. That is, the material data to be evaluated is previewed on the monitor screen, and the transmission target range (particularly, the transmission start point Pa and the transmission end point Pb) is visually confirmed to evaluate whether there is any sense of incongruity. If it is determined that the sending start point Pa (or sending end point Pb) should be shifted forward, a negative trim value is given and re-evaluated, or the sending start point Pa (or sending end point) If it is determined that it is better to shift Pb) backward, a positive trim value is given and re-evaluated.
[0012]
When performing this evaluation, if only the material data transmission target range (from Pa to Pb) is previewed, the transmission start point Pa is displayed at the same time as the preview starts, and at the same time as the display of the transmission end point Pb. Since the preview ends, it is considerably difficult to confirm the transmission start point Pa and the transmission end point Pb.
[0013]
Therefore, conventionally, as shown in FIG. 21, an identification screen (referred to as a “mask frame”) is provided for several seconds (for example, 2 to 5 seconds) before and after the transmission target range (hereinafter “transmission target frame”). Inserting is done.
[0014]
The mask frame must be easily distinguishable (visually distinct) from the transmission target frame. Therefore, a black single-color video signal called black burst (abbreviation: BB) and a multicolor video signal called color bar (abbreviation: CB) are prepared, and these two kinds of video signals are prepared. Are used properly according to the video content of the transmission target frame.
[0015]
22A shows a screen display example of a mask frame (hereinafter referred to as “BB mask frame 1”) when “BB” is used. The BB mask frame 1 is often applied to a transmission target frame having a bright color and high luminance. FIG. 22B is a screen display example of a mask frame (hereinafter referred to as “CB mask frame” 2) when “CB” is used. The CB mask frame 2 is often applied to an achromatic color tone or a blackish transmission target frame.
[0016]
Note that the BB mask frame 1 is one in which the levels of the three primary color components R, G, B and the luminance component Y are all 0, and corresponds to the black level of the video signal. The CB mask frame 2 has multicolored color bars arranged in the horizontal direction, and corresponds to a color bar test pattern used as a test signal for broadcast video equipment.
[0017]
The color bars are arranged in the order of “yellow”, “cyan”, “green”, “magenta”, “red”, and “blue” from the left, for example. These colors are obtained by appropriately setting the levels of the three primary color components R, G, B and the luminance component Y. For example, when the ratio of R, G, B, and Y is “1: 1: 0: 0.89”, “yellow” is obtained, and when “0: 1: 1: 0.70” is obtained, “cyan” is obtained. When “0: 1: 0: 0.59” is set, “green” is obtained, and when “1: 0: 1: 0.41” is set, “magenta” is obtained, and “1: 0: 0: 0”. .30 ”gives“ red ”, and“ 0: 0: 1: 0.11 ”gives“ blue ”.
[0018]
As described above, in the video server system, particularly during the mother preview, the confirmation work for each material data, that is, whether the correct material data corresponding to the material code is recorded, or the image quality and sound quality of the material data are good Various confirmation operations such as whether the trim value is appropriate must be performed.
[0019]
[Problems to be solved by the invention]
In the conventional video server system, the list displayed on the screen of the console is selected, the preview is executed, the above-described checking operation is performed, and if the result is satisfactory, the preview is OK. Information (for example, a flag) is registered in a list.
However, if the result of the confirmation operation is not satisfactory, for example, if the evaluation result of the trim value is “No”, it is necessary to repeat the confirmation operation (re-preview) after performing the trim adjustment described above. When handling a large amount of material data, there is a problem in that different types of work (adjustment work) are mixed and the flow of work is disturbed, resulting in a reduction in work efficiency and occurrence of work mistakes.
[0020]
Therefore, the problem to be solved by the present invention is to avoid disturbing the flow of preview work, thereby improving work efficiency and preventing work mistakes.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings, taking a “video server system” for broadcasting stations as an example.
[0044]
FIG. 1 is an overall configuration diagram of a video server system installed in a broadcasting station of a broadcasting company (especially a general broadcasting company; hereinafter, abbreviated as “company”). The illustrated video server system 10 (corresponding to the data recording / reproducing apparatus described in the gist of the invention) is divided into the upper station subsystem 100 in the station, the operation subsystem 200 (corresponding to the operation terminal described in the gist of the invention), The database subsystem 300 (corresponding to the holding means described in the gist of the invention), the mass storage subsystem 400 (corresponding to the data storage means described in the gist of the invention), the sending subsystem 500, and the like can be classified.
[0045]
Each of these subsystems has a role described later, and each subsystem has a general-purpose operating system (hereinafter referred to as “OS”) as necessary in order to efficiently realize all or a part of the responsible roles. ") May be included in the personal computer, office computer or workstation (hereinafter referred to as" PC ").
[0046]
In particular, as will be apparent from the following description, the operation subsystem 200 is a predetermined general-purpose OS excellent in a GUI (Graphical User Interface) environment in order to achieve a good man-machine interface with an operator. (For example, Windows 95/98 / NT / CE: a registered trademark of Microsoft Corporation) network compatible personal computers (including personal computers with network cards and hard disk drives, display devices, and input devices such as keyboards and mice) At least one unit (3 units for convenience) is included.
[0047]
A preferred configuration example of each subsystem will be described. First, the in-office upper subsystem 100 includes an upper management system (hereinafter referred to as “sales management system” for convenience) 101 installed in an organization department, a sales department, or the like.
[0048]
This sales management system 101 includes unique information for in-station management called a material code in material data (substance data of broadcast material; for example, video data and audio data such as CM material) received from the organization department or the sales department. Assigning, creating detailed information on material data (various attribute information related to material data), creating material data transmission order (so-called playlist and program organization table; hereinafter referred to as “playlist”) Is.
[0049]
Strictly speaking, the business management system 101 is connected to a network belonging to another work group different from the video server system 10, and the network and the video server system 10 are connected (LAN-LAN connection). In order to construct a so-called WAN (Wide Area Network), a data gateway 102 is provided in the intra-station upper subsystem 100.
[0050]
Although the data gateway 102 shown in the figure is not particularly limited, the data gateway 102 is configured by a network-compatible personal computer. For example, two network cards are inserted into a slot, and one network card is connected to the business management system 101, while the other Are connected to the LAN 600 of the video server system 10 to enable selective transfer of necessary data between the two networks.
[0051]
Here, when the data transfer direction from the business management system 101 to the video server system 10 is referred to as “downstream” and vice versa as “upstream”, the downstream data is “detailed information of material data (including material code)”. And “playlist”, and the upstream data is a list of material data (sending result list) that has been broadcast.
[0052]
Next, as described above, the operation subsystem 200 includes personal computers (three in the figure; refer to reference numerals 201 to 203) equipped with a general-purpose OS excellent in a GUI environment. This personal computer is placed on the desk of the staff member in charge of filing work, the staff member in charge of preview work, and the staff member in charge of transmission monitoring work.
[0053]
If these staff members are the same person, or if the filing work, the preview work, and the transmission monitoring work are not executed at the same time, one personal computer is sufficient. In other words, each application program software for filing, previewing and sending monitoring (or application program software integrating them) is installed on one PC, and an appropriate application program is selected according to the work contents to be executed. Just start.
[0054]
However, in practice, all or part of the filing work, preview work, and sending monitoring work are often performed in parallel. Therefore, as shown in the figure, a personal computer is used for each work person, that is, a personal computer for filing work. (Hereinafter referred to as “filing terminal”) 201, a personal computer for preview work (hereinafter referred to as “preview terminal”) 202, and a personal computer for transmission monitoring work (hereinafter referred to as “transmission monitoring terminal”) 203 are preferably installed separately. .
[0055]
Each of the terminals 201 to 203 is connected to the LAN 600 via a network card (not shown) inserted in the slot. It should be noted that a plurality of terminals may be installed for each work unit in preparation for the case where the same work is shared by a plurality of staff members.
[0056]
Next, the database subsystem 300 is configured by a personal computer (preferably a highly reliable server personal computer) equipped with a network-compatible database engine (for example, an SQL database engine; SQL is an abbreviation of Structured Query Language). A database table (hereinafter abbreviated as “DB_TBL”) that can freely refer to, update, and add record data from each terminal 201 to 203 of the operation subsystem 200 via this database engine is provided. DB_TBL has, for example, a table structure as shown in FIG.
[0057]
In FIG. 2, each of the horizontally long cells represents a data field (hereinafter simply “field”), and the entire frame represents one record. In each field, for example, “material code”, “status”, “DUR”, “sponsor name”, “material name”, “audio”, “video”,..., “Trim adjustment”,. • Appropriate names (field names) such as “Mark”,...
[0058]
The material code field is a key code field of the DB_TBL, and a unique material code issued by the sales management system 101 is stored in the key code field (material code field).
[0059]
The number of DB_TBL records depends on the number of material codes issued by the sales management system 101. For example, if the number of material codes issued by the sales management system 101 is n, the number of records in DB_TBL is also n. It becomes.
[0060]
Information stored in each field excluding the key code field of DB_TBL is various attribute information of material data corresponding to the key code (material code) of the record. For example, DUR is the length of the material, and the sponsor name is Material provider name, material name is material name, audio is audio mode, video is video mode, ..., trim adjustment is trim value of material data, ..., mark is tag information, ...・ Etc.
In particular, the mark (tag information) is binary information set at the time of the marking operation described later, and this binary information is a Boolean type (Boolean type) that can take a true value (True) and a false value (False). It can be. Hereinafter, the data type of the mark field is a Boolean type, and its initial value is False (representing “no mark”).
[0061]
Incidentally, the DB_TBL shown in the drawing has “previewed” as an attribute relating to material data of a certain material code (“CM0000000007”), and its DUR has a length of “00:15” (minute: second). , Sponsor name is “Bread food”, Material name is “Delicious breakfast”, Audio mode is “Stereo”, Video mode is “NTSC”, Trim adjustment is “0” “(Trim value 0),..., Mark is an initial value (False),...
[0062]
Some of these information, for example, material code, sponsor name, DUR, material name, audio mode, video mode, etc., maintain the contents shown in “Detailed information on material data” from the sales management system 101. Although it is fixed information that does not change as it is, for example, status, trim value, mark, and the like are variable information that can be changed by operations of the terminals 201 to 203 of the operation subsystem 200.
[0063]
The trim adjustment is an operation to determine (adjust) the SOM point at the time of sending the material data, as described at the beginning. This trim adjustment is an operation in the video server system 10 of the present embodiment. This can be performed using a predetermined GUI screen (details will be described later) on the filing terminal 201 or the preview terminal 202 of the subsystem 200.
[0064]
Next, the mass storage subsystem 400 is the core of the video server system 10 of the present embodiment. In short, a known mass hard disk management technology, typically RAID (Redundant Array of Inexpensive). A large amount of material data is stored in a large-capacity hard disk system built using Disk technology, and the material data is managed according to the detailed information of the material data, playlists, etc., and transmitted at a desired timing. (Broadcast).
[0065]
RAID includes RAID 0, RAID 1, RAID 3 and RAID 5 levels. RAID0 is a so-called stripe set, and uses a plurality of hard disks in order in blocks. RAID0 can read and write at high speed, but if the number of disks is n and the failure probability per device is x, the failure probability of the entire system is 1- (1-x).ⁿTherefore, there is a disadvantage that it is inferior in reliability.
[0066]
RAID1 is called a mirror set (or mirroring) and writes the same data to a plurality of hard disks. If any hard disk fails, no data is lost. The probability of losing data with RAID1 is xⁿThus, high reliability can be obtained, but the use efficiency of the disk is low.
[0067]
On the other hand, RAID3 has an intermediate performance between RAID0 and RAID1. That is, in RAID 3, a hard disk dedicated to parity (information for data restoration) is added to the configuration of RAID 0, and parity generated from data at the same logical block position of the hard disk constituting the RAID is written to the hard disk dedicated to parity. If one of the hard disks breaks, you can restore the broken data using the remaining hard disk data and parity. Therefore, data is not lost unless two hard disks including a hard disk dedicated to parity are broken at the same time.
[0068]
The failure probability of RAID3 is n (n−1) / 2 × (x²) Although not as high as RAID1, it has the advantage that it is much more reliable than a single hard disk and has a much higher efficiency of use of the disk (low redundancy) than RAID1.
[0069]
A weakness of RAID3 is that access to a hard disk dedicated to parity always occurs at the time of writing, and this access concentration tends to become a performance bottleneck. RAID5 has improved this point.
[0070]
RAID 5 does not have a disk dedicated to parity, but distributes parity information to each disk. Access concentration to the parity disk does not occur, and the weak points of RAID3 can be covered. However, the disk usage efficiency and reliability are equivalent to RAID3.
[0071]
In the mass storage subsystem 400 of the present embodiment, although not particularly limited, RAID 3 is used for storing video data, and RAID 1 is used for storing audio data.
[0072]
In order to improve fault tolerance, the large-capacity storage subsystem 400 has a dual configuration of main system A and system B (also referred to as “active / spare system”), and stores the same material data in each system. Like to do. System A includes SMS (Server Management System) 401a, IDC (Intelligent Device Controller) 402a, and video server 403a. System B also includes SMS (same) 401b, IDC (same) 402b, and video server 403b. A cassette control device 404 common to each system, a cassette autochanger 405, a material machine 406 controlled by the IDCs 402a and 402b of each system, and a monitor device 407 for displaying a preview image and the like.
[0073]
The monitor device 407 must be placed at a position where the screen can be clearly seen from each terminal of the operation subsystem 200, in particular, a staff member operating the preview terminal 202. If it is difficult to satisfy the condition (screen visibility) with one monitor device 407, another monitor device (referred to as “sub-monitor device” for convenience) is installed near the preview terminal 202. It is desirable to display the same screen as the monitor device 407 on the sub monitor device.
[0074]
The cassette autochanger 405 is similar to the conventional magnetic tape type transmission material storage device, and is used to create a so-called single tape and use it for data backup and library storage of the video servers 403a and 403b. It can also be used as an emergency backup machine when both video servers 403a and 403b are down.
[0075]
The cassette control device 404 mediates the allocation of various resources of the cassette autochanger 405 in response to resource requests from the filing terminal 201, the preview terminal 202, or the transmission monitoring terminal 203, and its basic function is SMS 401a, 401b. Therefore, the description of the SMS function described below will be used, and the description thereof will be omitted here.
[0076]
The SMS 401a and 401b, together with the IDCs 402a and 402b, mediate various resource allocations of the video servers 403a and 403b in response to resource requests from the terminals 201 to 203 of the operation subsystem 200.
[0077]
Note that a resource means a device such as an input / output channel of the video servers 403a and 403b, a connection point of a router, and a hard disk constituting a RAID. Also called a resource. Each of the terminals 201 to 203 can occupy and use the allocated device during the allocation period.
[0078]
Resource allocation must be done dynamically in response to requests from each terminal 201-203. This is because fixed allocation requires resources as many as the number of terminals, which is not efficient and is not practical because the system scale increases. By the way, when the resource allocation is made dynamic, it is necessary to take measures against competition and priority allocation to the same resource. The SMSs 401a and 401b perform arbitration of such contention and priority allocation (specific explanation of the arbitration operation will be described later).
[0079]
Next, the transmission subsystem 500 includes a host control system (hereinafter referred to as “transmission control system” for convenience) 501 installed in the transmission department, and further notification data (standby) from the transmission control system 501. A-system transmission control gateway 502a and B-system transmission control for updating table data (for example, detailed information on material data, contents of playlists, transmission result lists, etc.) according to commands and standby status data) A gateway 502b and a master switcher 503 common to each system are included.
[0080]
The transmission control system 501 transmits transmission play control information (PLAY command) to the IDCs 402a and 402b of each system, and on-air tally information (OATALLY command) from the master switcher 503 to the IDCs 402a and 402b of each system. Is supplied.
[0081]
Next, the operation will be described.
First, before describing the overall operation of the video server system 10, the operations of the SMS 401a and 401b that perform resource contention and resource priority allocation arbitration of the mass storage subsystem 400 will be described.
[0082]
FIG. 3 is a functional conceptual diagram of the SMS 401a, 401b (hereinafter, represented by the A-system SMS 401a). The SMS 401a is realized at least by an organic combination of software (OS and predetermined application program) and hardware. Two tasks {in the figure, an execution management task (abbreviation “EMT”) 900 and a resource information management task (abbreviation “RIMT”) 901} are provided.
[0083]
A “task” is a unit of program execution managed and controlled at the OS level. For example, MS-DOS can manage only one task at a time (so-called “single task”), while Windows 95/98 / NT / CE, UNIX, OS / 2, etc. manage by switching a plurality of tasks (so-called “multi-task”). Task "). When viewed from the user, the task is sometimes called a job. MS-DOS is a registered trademark of Microsoft Corporation, and OS / 2 is a registered trademark of IBM Corporation.
[0084]
Recently, it is rare to use a single-task OS such as MS-DOS except for special applications, and most of them are multi-task OS such as Windows 95/98 / NT / CE, UNIX or OS / 2. Is used. Therefore, in the present embodiment, the “task” is referred to in the technical background (multitask environment), but the meaning of this term is not limited. It may be a job or a program.
[0085]
The execution management task 900 provides an interface between the operation subsystem 200 and the IDC 402a. That is, when the execution management task 900 receives a resource request command (“control command” in the figure) from the operation subsystem 200, the execution management task 900 inquires the resource management task 901 whether or not the resource can be allocated, and the result (allocation permission or allocation denial). Is indicated to the operation subsystem 200 ("control result" in the figure).
[0086]
When the execution management task 900 receives an actual operation command (“control command” in the figure) for the allocated resource from the operation subsystem 200, the execution management task 900 notifies the resource management task 901 of the use of the resource and also notifies the IDC 402a. The operation instruction ("control instruction" in the figure) is transferred to notify the operation subsystem 200 of the operation execution result (normal end / abnormal end; "control result" in the figure) from the IDC 402a.
[0087]
The resource information management task 901 always keeps current information of resources to be managed by the SMS 401a in the latest state. This current information can adopt a database structure as shown in the figure as “resource information database 901a”, and further, the resource information database 901a is stored on the main memory of the SMS 401a in order to reduce overhead during access. Can be built. The resource information database 901a includes, for example, tables for user information, resource management information, material information, connection information, open management information, and error information.
[0088]
The user information table is unique identification information assigned to each terminal (the filing terminal 201, the preview terminal 202, and the transmission monitoring terminal 203) of the operation subsystem 200, or unique identification assigned to a staff member who operates each terminal. The resource management information table manages information indicating the current state of the resource, for example, a resource name, resource type, resource group name, resource state, resource communication state, reserved user name, and reservation as shown in FIG. Manage information such as priority.
[0089]
The material information table manages information of material data stored in the video server 403a, the connection information table manages connection information of resources, and the open management information table stores open resources (reserved or used resources). ) And the error information table manages information on the resource in which the error has occurred and information on the error content.
[0090]
In the resource management information table of FIG. 4, one of the holding information is representatively extracted and its meaning is explained. The resource name “SMS_1” indicates the A-system SMS 401a, and the resource type “SMS” Indicates SMS, ie, Server Management System, resource group GP_SMS indicates an SMS group including B-system SMS, resource status “available” indicates that it can be used at any time, and resource communication status “connection” indicates online The reservation user name “None” indicates that the resource is not currently reserved, and the reservation priority “0” indicates an initial value.
[0091]
FIG. 5 is a diagram illustrating an example of operations of the execution management task 900 and the resource information management task 901. In this figure, it is assumed that a resource request source (one of the terminals of the operation subsystem 200) generates a resource open command (OPEN command) having the following format, for example.
[0092]
OPEN [SN] [MD] [RSC] [PR] [USR]
Here, [SN] is an instruction number, and normally SN = 1. When several commands are consecutive, SN = 2, SN = 3,. [MD] is a resource open mode designation. In the reproduction mode, MD = PLAY, and in the recording mode, MD = REC. [RSC] is a resource designation. For example, RSC = HDS_1. When AV1 is set, a predetermined resource having a resource name “HDS_1.AV1” is designated. Note that the relationship between RSC and resource designation depends on the registered contents (particularly resource names) in the resource management information table of FIG.
[0093]
[PR] is a priority designation. When PR = 100, the lowest priority is set, and the closer to 0, the higher the priority. [USR] specifies user information of the resource request source. For example, when USR = USER_1, a resource allocation request is issued from a user or terminal having the name “USER_1” (unique identification information).
[0094]
For example, MD = PLAY, RSC = HDS_1. The execution management task 900 that has received the OPEN instruction of VA1, PR = 100 and USR = USER_1 sends these pieces of information (MD = PLAY, RSC = HDS_1.VA1, PR = 100 and USR = USER_1) to the resource information management task 901. Notice.
[0095]
The resource information management task 901 refers to each table of user information, resource management information, material information, connection information, open management information, and error information, and determines whether or not the requested resource allocation is possible. For example,
(A) "USER_1" is not registered in the user information table,
(B) Resource information management table HDS_1. The resource status of AV1 is not “available”,
(C) Resource information management table HDS_1. AV1 resource communication status is not "connected"
(D) Resource information management table HDS_1. The reservation user name of AV1 is other than “None”, and the reservation priority is set to a value smaller than the value of [PR].
If either of the conditions is satisfied, the resource allocation request is rejected. Otherwise, the resource allocation request is granted and a new entry is created in the open management table. The above (a) to (d) are all resource allocation arbitration conditions, and (d) is the priority arbitration condition.
[0096]
The resource information management task 901 notifies the execution management task 900 of the resource allocation permission or rejection result, and the execution management task 900 transfers the notification to the resource request source (operation subsystem 200), but the resource allocation is permitted. If so, the execution management task 900 transfers information called a stream ID (for example, CSTAT SID = n; n is an arbitrary integer) to the resource requester (operation subsystem 200).
[0097]
This stream ID is a unique identification code corresponding to an open command for which resource allocation is permitted. The resource requester (operation subsystem 200) subsequently uses this stream ID to sequentially issue control commands for the allocated resource. Can occur.
[0098]
For example, when instructing reproduction, “PLAY SID = n” is generated at the resource request source (operation subsystem 200). When the stream ID is not used, an instruction including a lot of information equivalent to the resource request must be generated, such as “PLAY REC = IOP_1 MD = PLAY PR = 100”, but the stream ID is used. As a result, information can be reduced and instructions can be simplified.
[0099]
Next, the overall operation of the video server system 10 of the present embodiment will be described.
Material data such as CMs produced inside or outside the office is stored in a portable storage medium such as magnetic tape and delivered to the department in charge of the broadcaster (for example, organization department or sales department). (This will be referred to as “arrival” for convenience). The arrival is not limited to the portable storage medium. Although there may be an arrival using a communication line such as a dedicated line, that is, an arrival of only data, in the following description, for the sake of simplification, we will proceed with an example of arrival using a portable storage medium.
[0100]
When the arrival of goods occurs, the person in charge of the department operates a terminal (not shown) of the sales management system 101 and executes a reception process for each material data. In this reception process, an in-company code (that is, a material code) for uniquely identifying each material data is generated. As described above, the material code must be a unique code without duplication. The format of the material code can be, for example, a combination of an appropriate prefix character and a multi-digit serial number. The prefix character can include an appropriate character (or character string) indicating the type of the material code. For example, in the case of a CM material, it can be “CM”.
[0101]
A unique material code can be obtained by automatically generating the serial number while counting up automatically during the business continuation period of the business. For example, if the prefix is “CM” and the serial number is a numeric value with a 10-digit zero suppression (insert a character 0 in a blank digit), a unique material code from “CM0000000001” to “CM999999999999” is generated. Can do. Alternatively, an appropriate character string representing the fiscal year or the fiscal year end may be combined with a serial number, and the serial number may be automatically generated while the serial number is reset to the initial value every time the fiscal year or the fiscal period changes.
[0102]
In the reception process, in addition to the generation of the material code, various attribute data related to the material data are input to create “detailed information on the material data”. The attribute data includes, for example, material data length (DUR), material data provider name (sponsor name), material data name (material name), and type of audio data included in the material data (monaural, stereo, etc.) The types of video data included in the material data (NTSC, PAL, etc.).
[0103]
When the reception processing in the sales management system 101 is completed, the “material data detailed information” including the material code and the attribute data is transferred from the reception management system 101 via the data gateway 102 to DB_TBL of the database subsystem 300. It is additionally registered. For example, when the business management system 101 receives material data “CM0000000007” and creates detailed information on the material data, the record data of FIG. 2 is stored in the DB_TBL of the database subsystem 300 after the reception process is completed. A new record is added and registered. However, at the stage of adding a new record, the status field information among the field data of the record data in FIG. 2 is “blank” (or a zero-length character string or NULL value), and the trim setting field Both of the mark field information are initial values (trim adjustment = 0, mark = False).
[0104]
A staff member in charge of filing work, a staff member in charge of preview work, or a staff member in charge of transmission monitoring work operates each terminal (filing terminal 200, preview terminal 201 and sending monitoring terminal 203) of the operation subsystem 200, and the database subsystem. While performing access to the system 300 or the mass storage sub-400 system, it performs its own work.
[0105]
Here, the work in charge can be classified into playlist registration work, material filing work, material preview work (including on-air preview work), unification tape creation work and delivery monitoring work. .
[0106]
As described above, in this embodiment, the playlist transferred from the sales management system 101 can be automatically registered in the database system 300 via the data gateway 102. No work is necessary. However, if a trouble occurs in the sales management system 101 or if the data connection with the sales management system 101 fails, the playlist may be delivered in a portable storage medium such as a floppy disk. Therefore, in preparation for such a case, it is desirable that the playlist can be directly registered in the database system 300 or can be remotely registered from any terminal of the operation subsystem 200.
[0107]
The material filing work is a work for registering (accumulating) material data entities (video data and audio data; hereinafter, represented by video data) in the mass storage subsystem 400 in accordance with “detailed information of material data”. The work is performed by operating the filing terminal 201. That is, a portable storage medium containing material data is set in the material machine 406, and the material machine 406 is remotely operated from the filing terminal 201 to register required material data in the mass storage subsystem 400.
[0108]
In addition, the material preview operation is a confirmation operation of material data accumulated in the mass storage subsystem 400 (image quality, sound quality, etc. check operation; mother preview) or a collation operation with a playlist or a program organization table (transmission rehearsal). Or on-air preview), and this operation is performed by operating the preview terminal 202.
[0109]
That is, the material data stored in the mass storage subsystem 400 is read by operating the preview terminal and displayed on the monitor device 407 to check the image quality and sound quality (mother preview), or to play list and program organization Check whether playback is in the order shown in the table (on-air preview).
[0110]
The sending monitoring work is a work of sending (broadcasting) the material data sequentially according to the play list for the day, and most of the work is an automated work that does not require human intervention.
[0111]
FIG. 6 is a diagram showing a GUI screen (corresponding to the user interface described in the gist of the invention) of the filing terminal 201. A staff member in charge of filing work performs necessary work interactively while viewing the GUI screen 910. In the illustrated GUI screen 910, “Filing” is displayed in the title bar 911, but it is not dedicated to filing work. It is also used for a GUI screen on the preview terminal 202. That is, it is a GUI screen for both filing work and preview work.
[0112]
Hereinafter, the form layout of the GUI screen 910 will be described. An appropriate title message (“Filing A system” in the figure) is displayed on the title bar 911. Note that “A system” in the title message indicates the current system (A system or B system) of the mass storage subsystem 400 connected to the terminal displaying the GUI screen 910. The title bar 911 further displays an appropriately designed image object 911a, a “close” button 911b, a “maximize” button 911c, a “minimize” button 911d, and the like on the GUI screen 910.
[0113]
A menu bar 912 is arranged below the title bar 911. In the menu bar 912, several menu items (file “F”, material data “E”, display “U”, operation “O”, option “P”, and help “H” in the figure) are set. . When you click on any menu item (left mouse button operation; the same applies below), a pull-down submenu item is displayed.
Although illustration is omitted, one of the submenu items is “extraction condition specification” described later. By selecting this submenu item (extraction condition specification), the “extraction condition specification” form (see FIG. 17) is opened.
Note that the alphabet (“F”, “E”, “U”, “O”, “P” and “H”) of the menu item is pressed at the same time as a predetermined function key (for example, “Alt” key). Indicates a shortcut key for calling a menu item to be performed.
[0114]
A command button CTL group 913 in which a plurality of command button controls (hereinafter “control” is abbreviated as “CTL”) is arranged horizontally is arranged under the menu bar 912. Each command button CTL is frequently used. Submenu items (submenu items registered in the menu bar 912 or other menu items) are assigned.
[0115]
Here, “control” (CTL) is a kind of reusable program module, and in particular, various components for GUI screen design that are attached (or sold separately) in advance to a visual program development tool. That means. For example, VBX (Visual Basic Extension), OCX (OLE custom control), class library, remote OLE, ActiveX control, etc. are representative examples.
[0116]
When designing a GUI screen, it is possible to lay out the screen simply by selecting an appropriate control according to the application and pasting the control on the screen (form; Form), so the development man-hours can be greatly reduced.
[0117]
Every control has (all or part of) a programming interface called a property, method or event. These programming interfaces correspond to skeletons in the object-oriented methods (Object Oriented Methods). A property specifies a static attribute of the control, a method specifies a behavior of the control, and an event specifies a behavior corresponding to an external factor of the control.
[0118]
Incidentally, since a general command button CTL has two properties and an event, by setting a desired value to these interfaces on a form or code, the static attribute and external of the command button CTL are set. The operation corresponding to the factor can be programmed arbitrarily.
[0119]
For example, if True is set in the available property (enabled property) of the command button CTL, the command button CTL can be used and an event such as a click or a double click can be accepted. A procedure (program) can be executed. Alternatively, when False is set in the usable property, the command button CTL can be disabled to prohibit the execution of the above procedure, and the title display can be made light to clearly indicate the unusable.
[0120]
Further, there is a CTL similar to the command button CTL called a toggle button CTL. The toggle button CTL has a value property (Value property), and the reference value of the Value property becomes True when the toggle button CTL is clicked and pressed (hereinafter referred to as “ON state”), and is jumped out (hereinafter referred to as “ In the “OFF state”), it becomes False. The Value property can be set externally at the time of designing the form or executing the code. For example, the toggle button CTL is turned on when setting the Value property to True from the code, and turned off when setting the False.
[0121]
A status area 918 including a list box CTL 914 and a plurality of text boxes CTL 915 to 917 is provided at the bottom of the GUI screen 910. The list box CTL 914 displays a list of message information such as system errors in time order. When confirming the message information of the old time, a list is displayed by clicking the arrow button of the list box CTL 914, and a desired list row may be selected. The text boxes CTL 915 to 917 include, for example, a character string indicating that the filing work or the preview work is being executed or the work has ended, a preview mode (single execution mode / continuous execution mode), and the number of material data to be previewed ( The denominator displays the number of all material data).
[0122]
The wide area between the command button CTL group 913 and the status area 918 on the GUI screen 910 is divided into four areas. From the position of each area, for convenience, an upper left area 919, an upper right area 920, a lower left area As will be described later, the upper left area 919 is for displaying material data list, the upper right area 920 is for displaying detailed information of one material data, and the lower left area 921 is a cue-up operation. The lower right area 922 is allocated for filing / preview operations.
[0123]
FIG. 7 is a layout diagram of the upper left area 919. In this area, one data sheet CTL 919a composed of a number of rows and columns is arranged. True is set in the scroll property of the data sheet CTL 919a, and a vertical scroll bar 919b and a horizontal scroll bar 919c are displayed. By using these scroll bars 919b and 919c, it is possible to display rows and columns hidden outside the area.
[0124]
Each column (item) of the data sheet CTL 919a has item names such as “material code”, “status”, “DUR”, “sponsor name”, “material name”, “voice”,. These items are set, and these items are linked to fields having the same name in DB_TBL (see FIG. 2) of the database subsystem 300.
[0125]
By pointing and clicking an arbitrary line in the data sheet CTL919a with the mouse, the line can be selected (actually, material selection is performed on a main screen (not shown). Although there is no reaction even if the row of CTL 919a is selected, the following description will be made assuming that material selection is performed on this data sheet CTL 919a for convenience). For example, in the figure, the second line from the top (the line of the material code “CM0000000007”) is highlighted, indicating that this line is in a selected state. The “status” of each row represents the current state of the material data of that row. For example, blank represents unrecorded (unfiled), “recorded” represents filing completion, and “previewed” represents mother preview completion.
[0126]
When filing work is performed, a line whose “status” is blank and a line that matches the material code to be filed is found, the line is selected, and a filing operation described later is executed. Or, when performing the preview operation, find a line whose “status” is “recorded” and matches the material code to be previewed, select the line, and perform the preview operation described later. Execute.
[0127]
An image object for visualizing the selection operation of the filing work and the preview work is displayed at the top of each row of the data sheet CTL 919a. The first image object 919d is a stylized cylindrical figure (see FIG. 8A), and this image object 919d is linked to “recorded” in “status”. The second image object 919e is a display screen (see FIG. 8B), and this image object 919e is linked to “Previewed” in “Status”.
[0128]
In general, in the computer world, it is customary to represent a hard disk with a cylindrical figure. Therefore, the first image object 919d is stored in the mass storage subsystem 400 of material data, that is, “recorded” of “status” is recorded. "Is visualized and expressed. Further, the second image object 919e, which is an image of the display screen, can remind the monitor device 407, so that the display of material data on the monitor device 407, that is, “preview” of “status” is visualized. Express.
[0129]
Therefore, it is possible to specify the line to be filed and previewed by simply looking at the image objects 919d and 919e without reading the character string of “status” one by one, and the efficiency of filing work and preview work can be improved. Since there are few misreads compared with character string reading, the reliability of the work can be improved.
[0130]
As the image object, not only the first image object 919d and the second image object 919e described above, but also two other types of image objects in which a part of these designs are arranged are prepared. FIG. 8C is an enlarged view of the second image object 919f obtained by arranging a part of the design of the first image object 919d, and FIG. 8D is an example of the design of the second image object 919e. It is an enlarged view of the 4th image object 919g which arranged the part.
[0131]
As can be understood from the figure, the third and fourth image objects 919f and 919g have the same visual effect as the first and second image objects 919d and 919e on the design of the user. Appropriate design (in the figure, a design simulating a flag) has been added.
Hereinafter, this additional design will be referred to as a “mark” for convenience, and the first and second image objects 919d and 919e will be referred to as “no mark” image objects, and third and fourth images as necessary. The objects 919f and 919g are referred to as “marked” image objects.
[0132]
FIG. 9 is a layout diagram of the upper right area 920. In this area, a tab CTL 920e having four tab buttons CTL 920a to 920d of “general”, “material configuration”, “user information”, and “others” is provided. For example, when the general tab button CTL 920a is selected, the following CTLs are displayed on the tab CTL 920e.
[0133]
Specifically, a material code display text box CTL920f, a status display text box CTL920g, an audio mode display list box CTL920h, a video type display list box CTL920i, a material classification display list box CTL920j, and a sponsor name display Text box CTL920k, text box CTL920m for displaying the material name, text box CTL920n for displaying the period of use / starting, text box CTL920p for displaying the period of use / ending, text box CTL920q for displaying the TotalDUR, text for displaying the number of components Box CTL920r, List box CTL920s for displaying Video type, List box CTL920t for displaying Audio type, DU Text box CTL920u for the display, text box CTL920v for dubbing material display, the original material SOM (SOM stands for Start Of Message), such as a text box CTL920w for display is displayed.
[0134]
Then, in these CTLs, detailed information of the selected row of the data sheet CTL 919a (see FIG. 7) (more precisely, record information of DB_TBL of the database subsystem 300 having a material code that matches the material code of the selected row) Is displayed.
[0135]
For example, in the example of FIG. 9, detailed information regarding the material data “CM0000000007” corresponding to the selected row of the data sheet CTL 919a of FIG. 7 is displayed in each CTL. The detailed information is each field information of “CM0000000007” in DB_TBL of the database subsystem 300 (see FIG. 2).
[0136]
In FIG. 9, “recorded” in “status” indicates that the material data “CM0000000007” has been recorded (stored) in the mass storage subsystem 400, and “stereo” in “audio mode” is the same. It shows that the audio data included in the material data is data of a stereo system (there are other systems such as “monaural” and “audio multiplexing”).
[0137]
In addition, “NTSC” of “video type” indicates that the video data included in the material data is NTSC (National Television System Committee) method (in addition to “PAL: Phase Alternation by Line color television” or “SECAM: Sequential molecular qualification”). "T" in "Material Category" is an abbreviation for Time CM (in addition, there is a category such as SB: Station Break).
[0138]
Also, the “use period” is, for example, a material with a reception start date or a deadline date (end date) such as a CM material with a prize, and the start date and / or the end date (however, the use period is The one not present indicates a blank), and the value of “TotalDUR” (“00:15” in the figure) indicates the DUR of the entire material.
Also, “D” of “Video” and “Audio” indicates the first material configuration, and the value of “DUR” (“00:15” in the figure) indicates the DUR of the first material configuration.
Further, the value of “dubbing material” (entering a character string; blank in the figure) indicates the material code of the dubbing source material, and the value of “original material SOM” (“00:00:00” in the figure) is the original. The SOM time code of the material is shown.
[0139]
FIG. 10 is a layout diagram of the lower left area 921, in which two option buttons CTL 921 a and 921 b grouped, a command button CTL 921 c named “RESET”, and “TCSET” are named. A command button CTL921d, a command button CTL921e named "CUEUP", a command button CTL921f named "VAR", a text box CTL921g for displaying the CUEUP time, and a TCSET time (TC at the current position) display A text box CTL921h, a text box CTL921i for displaying a playback speed, and command buttons CTL921j, 921k, 921m, and 921n for “play”, “stop”, “REV”, and “FWD” are provided.
[0140]
Note that the text box CTL921g for displaying the CUEUP time and the text box CTL921i for displaying the playback speed are provided with two small command buttons (also called spin buttons) CTL921p and 921q for up-down each input value. Yes.
[0141]
Here, the function of each CTL will be described. The two option buttons CTL 921a and 921b are for selecting either the server TC or the material machine TC. The material machine TC can be selected when an unfiled material is selected, and the server TC can be selected when a recorded or previewed material is selected. Note that TC is an abbreviation for Time Code.
[0142]
The command button CTL 921c named “RESET” is for returning (resetting) the value of the text box CTL 921g for displaying the CUEUP time to the initial value (00:00:00).
The command button CTL921d named “TCSET” is for setting the value of TC displayed in the text box CTL921h for displaying the TCSET time in the text box CTL928g.
The command button CTL 921e named “CUEUP” is for cueing up the currently selected material data to the cue position specified in the text box CTL 928g.
[0143]
The command button CTL 921 f named “VAR” is for reproducing the material at the reproduction speed designated in the text box CTL 921 i.
The CUEUP time display text box CTL921g is for designating the cue-up cueing position.
A text box CTL921h for displaying the current position is for displaying the current TC (the value is counted up during video reproduction).
[0144]
The reproduction speed display text box CTL921i is for designating the reproduction speed at the panel preview. The initial value is “× 1” (1 time). By clicking two small command buttons CTL921g on the right end, it can be changed to ± 1/16, ± 1/8, ± 1/4, ± 1/2, ± 1, ± 2, and ± 4. However, decimal values and 0 values cannot be set.
[0145]
Command buttons CTL 921j, 921k, 921m, and 921n for “play”, “stop”, “REV”, and “FWD” play the selected material data, stop (stop) playback, and This is for returning the screen by one frame (REV) or moving the currently playing screen forward by one frame (FWD).
[0146]
FIG. 11 is a layout diagram of the lower right area 922. In this area 922, there are six toggle buttons CTL 922a, 922b, 922c, 922g, 922h, 922i and six command buttons CTL 922d, 922e, 922f, 922j. , 922k, 922m, one progress bar CTL922n, two text boxes CTL922p, 922q, and one slide volume CTL922r.
[0147]
The function of each CTL will be described. First, the toggle buttons CTL 922a to 922c are for selecting a system to be previewed (system A / system B of the mass storage subsystem 400). These toggle buttons CTL 922a to 922c are grouped (so-called option groups), and when one is selected (the toggle button CTL 922a at the left end is selected in the figure), the button remains in the ON state, and the other buttons The button is maintained in the OFF state. Buttons with “A” in the title are for A system selection, buttons with “B” are for B system selection, and buttons with “A” and “B” are for both system selection.
[0148]
A toggle button CTL922g (corresponding to the first control or toggle button control described in the gist of the invention) is arbitrarily operated during filing work or preview work, and the toggle button CTL922g is turned on / off ( That is, the value of the Value property) depends on the presence / absence of the image object displayed in the selected row of the data sheet CTL 919a and the absence / "marking" of the image object.
[0149]
That is, when an arbitrary row of the data sheet CTL 919a (see FIG. 7) is selected and the image object is not displayed on the selected row, the Value property is False (therefore, the toggle button CTL 922g is in the OFF state), or If the image object being displayed in the selected row is “no mark” (first image object 919d or second image object 919e), the Value property is False (therefore, the toggle button CTL922g is in the OFF state), or , “Marked” (third image object 919f or fourth image object 919g), the Value property is set to True (therefore, the toggle button CTL922g is in the ON state). That.
[0150]
As described above, the Value property of the toggle button CTL922g can be changed by clicking the mouse. In the click event of the toggle button CTL922g, a procedure described later ("mark" toggle button_Click procedure; see FIG. 16) is registered. This procedure refers to the Value property of the toggle button CTL922g and corresponds to the reference value. Thus, the image object being displayed in the selected row of the data sheet CTL 919a is switched from “without mark” to “with mark” (or vice versa).
[0151]
For example, when the toggle button CTL 922g is clicked while the first image object 919d is displayed, the first image object 919d is switched to the third image object 919f, and when clicked again, the third image object 919f is changed. Switch to the first image object 919d again. When the toggle button CTL 922g is clicked while the second image object 919e is displayed, the second image object 919e is switched to the fourth image object 919g, and when clicked again, the fourth image object 919g is changed. Switch again to the second image object 919e.
[0152]
The toggle buttons CTL 922h and 922i are for setting a mask mode for preview work. These toggle buttons CTL922h and 922i are grouped, and when one is selected (the right toggle button CTL922i is selected in the figure), the button is maintained in the ON state and the other buttons are in the OFF state. To maintain.
[0153]
A toggle button CTL922h on the left side with an image object of a black design (or a design mainly made of black) pasted in the title is for specifying a mask mode using the BB mask frame 1 (see FIG. 22A). The right toggle button CTL922i with the image object imitating a color bar in the title is for designating a mask mode using the CB mask frame 2 (see FIG. 22B).
[0154]
The command button CTL922d is for designating execution of filing work. When this button is pressed, the material data corresponding to the material code in the selected row of the data sheet CTL 919a (see FIG. 7) is registered (accumulated) in the mass storage subsystem 400. However, the command button CTL922d is disabled during preview work.
The command button CTL922j is for designating execution of the preview work. When this button is pressed, the material data corresponding to the material code in the selected row is read from the mass storage subsystem 400 and displayed on the monitor device 407. However, at the time of filing work, the command button CTL922i is disabled.
[0155]
The command button CTL 922e is used to invalidate the recorded state when the “status” of the selected row is “recorded”. That is, when the command button CTL922e is clicked, the material data (material data corresponding to the material code of the selected row) accumulated in the mass storage subsystem 400 is deleted, and a blank is displayed in the “status” of the selected row. It is set and the image object in the selected row is hidden.
[0156]
The command button CTL922f is for clearly indicating the normal end of the preview work. That is, the user operates (clicks) when all the confirmation results such as the image quality, sound quality, and trim value of the material data confirmed in the preview operation are satisfactory. When this command button 922f is clicked, the character string “Previewed” is set in “Status” of the selected line.
[0157]
The command button CTL922k is for instructing to cancel the filing work or the preview work being executed.
The command button CTL922m is for closing (closing) the GUI screen 910 (see FIG. 6). However, the command button CTL922m is disabled during the filing work or the preview work.
[0158]
The progress bar CTL922n is for displaying the progress status of the preview work. The progress rate of the work is displayed as the length of the bar graph. When the bar graph reaches the maximum length, the progress rate is 100%, that is, the preview work is completed.
[0159]
The text box CTL922p is for designating the reproduction speed at the time of preview. The initial value is “× 1” (1 time). However, the values that can be set are up to +4, and decimal values, 0 values, and negative values cannot be set. Or, by clicking two small command buttons (also called spin buttons) CTL922s on the right end, the range from 1/16 to 4 (specifically, +1/16, +1/8, +1/4, +1/2, +1, +2, +4) can change the value.
[0160]
The text box CTL922q is for designating a trim value for the material data of the selected line. The setting range is an integer value within ± j. j is a value that does not exceed the number of discarded frames in FIG. 20 (for example, j = 10). The setting value can also be changed by clicking two small command buttons (also called spin buttons) CTL922t on the right end. The condition of the set value is the same as that of the text box CTL922q (an integer within ± j).
[0161]
The slide volume CTL922r is for designating a trim value for the material data of the selected row, and the setting range is an integer value within ± j. The trim value is reflected in the text box CTL922q on the left side.
[0162]
Next, description will be made regarding the marking operation in this embodiment (for example, an operation performed during the preview operation).
FIG. 12 is a flowchart of the entire marking operation according to the present embodiment including user operations. In this flowchart, a user (for example, an operator of the preview terminal 202) firstly, in step S1, a data sheet CTL 919a (see FIG. 7) on which material data to be previewed (hereinafter referred to as “CM0000000007” material data) is displayed. ) And click the “Preview” button (command button CTL922j).
[0163]
The preview terminal 202 (more precisely, a preview application program being executed on the preview terminal 202 or an integrated application program including a preview application; hereinafter referred to as the preview terminal 202 for convenience) performs the click operation of the “preview” button. In response, a resource request control command necessary for sending “CM0000000007” is output to the SMS 401 a of the mass storage subsystem 400, and the SMS 401 a of the mass storage subsystem 400 stores the resource information database of the resource information management task 901. Refer to determine whether to accept or reject a resource request.
[0164]
If the resource required for sending “CM0000000007” is available, or if the priority is low even if the resource is occupied, the resource information management task 901 accepts the resource request (resource reservation), and a response indicating that A unique stream ID is returned to the requesting preview terminal 202.
[0165]
The preview terminal 202 displays the current mask mode (for example, the mode in which the CB mask frame 2 is used when the right toggle button CTL922h is selected) and the current trim setting value (for example, the trim value shown is 0). An instruction for reproducing “CM0000000007” is generated by applying it, and a stream ID is added to this instruction, and the instruction is transferred to the SMS 401 a of the mass storage subsystem 400.
[0166]
The SMS 401a of the mass storage subsystem 400 identifies the reserved resource by interpreting the stream ID, reads the material data of “CM0000000007” from the A-system video server 403a using this resource, Trimming is performed by applying the trim setting value to the material data, and the mask frame (for example, CB mask frame 2) designated in the mask mode before and after the trimmed material data is defined for a predetermined time (for example, 2 to 2). 5 seconds) and control to send to the monitor device 407.
[0167]
The user visually checks the screen display of the monitor device 407 to evaluate the image quality, sound quality, and appropriateness of the trim value, and if the evaluation result is good (Y determination in step S2), there is no material data to be previewed (step S2). The preview operation in step S1 is repeated until N is determined in S3.
On the other hand, as a result of previewing arbitrary material data, if the evaluation result of image quality, sound quality or trim value is unsatisfactory and the target material data is not re-previewed or re-recorded, the step Proceed to the marking process in S4.
[0168]
In this marking process, the user clicks the “mark” button (toggle button CTL922g) in step S4a. If the selected row of the current data sheet CTL 919a is “CM0000000007”, as shown in FIG. 7, the “status” of this selected row is “recorded”, and the first image object 919d (no mark) is at the beginning of the row. Is displayed. Accordingly, the “mark” button (toggle button CTL922g) after the click is turned on, and True is set in its Value property.
[0169]
Next, in step S4b, the value (True) of the value property of the toggle button CTL922g is referred to, and this reference value is written in the mark field (see FIG. 2) of DB_TBL of the database subsystem 300, and the content of the data sheet CTL 919a is stored in DB_TBL. Update to correspond to the latest state of. As a result, as shown in FIG. 13, the image object at the head of the selected row of the data sheet CTL 919a is switched from the first image object 919d (without mark) to the third image object 919g (with mark).
[0170]
After the above marking process (step S4), the preview operation in step S1 is repeated until there is no material data to be previewed (N determination in step S3), and an unexpected evaluation result is obtained during the repetition. In the case where the target material data is not re-previewed or the material data is not re-recorded, the marking process (step S4) is executed.
[0171]
FIG. 13 is a display example of the data sheet CTL 919a after performing several mark processings. In this example, for convenience, the second row, the seventh row, the fourteenth row, the fifteenth row, the nineteenth row. Marked image objects (third image object 919f or fourth image object 919g) are displayed at the beginning of each of the eyes and the 23rd row.
[0172]
Therefore, according to this display example, the preview result for each material data of “CM0000000007”, “CM0000000012”, “CM0000000019”, “CM0000000020”, “CM0000000024” and “CM0000000028” having a marked image object at the beginning of the line. It is clearly indicated to the user that there were some unintended points in the evaluation results (image quality, sound quality, trim value, etc.).
[0173]
The description of the operation of the marking operation in the present embodiment is as described above, but this operation is described as follows when it is described in the event procedure related to the preview processing.
[0174]
FIG. 14 is a simplified flowchart of the click event procedure (data sheet_Click) of the data sheet CTL 919a. This procedure is executed in response to an operation of selecting an arbitrary row of the data sheet CTL 919a. That is, it is executed in response to the operation of step S1 in FIG. 12 (material data selection operation).
[0175]
When the procedure is executed, first, an image object (any one of the first to fourth image objects 919d to 919g) is displayed in the image item set in the current row (selected row) of the data sheet CTL 919a in step S11. In step S12, the value property of the “mark” toggle button (toggle button CTL922g) is set to False, and if it is displayed, the image object is displayed in step S13. It is determined whether it is “marked”, that is, whether it is the third image object 919f or the fourth image object 919g, and if it is marked, step S14 (described in the gist of the invention). Equivalent to mark information generation means) Is set to True Value property of over click "toggle button (toggle button CTL922g), if it is not marked, is set to False in the Value property of the" mark "toggle button (toggle button CTL922g) in step S12.
[0176]
By the above procedure processing, the operation of step S1 in FIG. 12, that is, the row of the data sheet CTL 919a is selected to specify the material to be previewed, and the presence or absence of the image object in the selected row or the type of image object (marked) In response to “/ No mark”, an operation of performing ON / OFF control of the “mark” toggle button (toggle button CTL922g) can be realized.
[0177]
FIG. 15 is a simplified flowchart of the “Preview” command button click event procedure (Preview_Click). This procedure is executed in response to a click event of the command button CTL922j of FIG. That is, it is executed in response to the operation (preview execution operation) in step S1 in FIG. When the procedure is executed, first, in step S15, the material code of the current row (the selected row) of the data sheet CTL (data sheet CTL 919a in FIG. 7), for example, “CM0000000007” is fetched, and the material code is stored as a temporary variable (for example, , A variable named “Preview Code Variable”).
[0178]
Next, in Step S16, it is determined whether or not the option value of the MASK option group (a group of two toggle buttons CTL922h and 922i) is “1”. Here, if the option value “1” is assigned to the ON state of the left toggle button CTL922h, if the option value = “1”, “BB” is set to the MASK variable in step S17, and In step S19, the current trim value (set value of the text box CTL922q) is set in the trim value variable, and the process proceeds to step S20. On the other hand, if the option value ≠ “1”, the MASK variable is set to “CB” in step S18. . ”And the current trim value (set value of the text box CTL922q) are set in the trim value variable in step S19, and the process proceeds to step S20. In step S20, the material data is previewed.
[0179]
The material data to be previewed is material data corresponding to the material code (“CM0000000007”) set in the temporary variable. In this preview process (step S20), a resource request process to the large-capacity storage subsystem 400 is performed, and a transmission command process of material data to which the selected mask frame and the set trim value are applied is performed. Performs visual confirmation of the preview screen transmitted from the video server 403a of the mass storage subsystem 400 to the monitor device 407 in accordance with the transmission command processing.
[0180]
By the above procedure processing, the remaining operation of step S1 in FIG. 12, that is, the material of “CM0000000007” to which the mask frame being selected and the trim setting value are applied, which is executed in response to the pressing operation of the “preview” button. A data preview operation (output operation to the monitor device 407) and its confirmation operation can be realized.
[0181]
FIG. 16 is a simplified flowchart of the “Mark” toggle button click event procedure (“Mark” toggle button_Click). This procedure is executed in response to the click event of the toggle button CTL922g of FIG. That is, it is executed in response to the operation of step S4a in FIG.
[0182]
When the procedure is executed, first, DB_TBL of the database subsystem 300 is opened in step S21. Next, in step S22, the Value property of the toggle button CTL922g is set to the temporary variable Tmp. Here, the value of Tmp is True when the toggle button CTL922g is in the ON state, and False when it is in the OFF state.
[0183]
Next, in step S23 (corresponding to the storage means described in the gist of the invention), the value of Tmp is set in the mark field (see FIG. 2) of the current record of DB_TBL (the record corresponding to the selected row of the data sheet CTL919a). After DB_TBL is closed in step S24, the display of data sheet CTL919g is updated in step S25 to reflect the latest contents of DB_TBL, and the procedure is terminated.
[0184]
By the above procedure processing, the operation of step S4 (step S4a and step S4b) of FIG. 12, that is, the data update operation and data sheet of the DB_TBL mark field executed in response to the pressing operation of the “mark” toggle button. The display update operation of the CTL 919a can be realized.
[0185]
As described above, in this embodiment, the GUI screen 910 in FIG. 6 can be displayed on the display of the filing terminal 201 or the preview terminal 202 of the operation subsystem 200, and the lower right area 922 of the GUI screen 910 is displayed. As shown in FIG. 11, a “mark” toggle button (toggle button CTL922g) can be displayed.
[0186]
Then, by switching the “mark” toggle button from the OFF state to the ON state, the first or second image object 919d, 919e being displayed in the selected row of the data sheet CTL 919a is displayed as the third or third “with mark”. 4 image objects 919f and 919g.
[0187]
Therefore, when unpredictable material data (hereinafter referred to as “NG material data”) is found in the preview result, the “NG” is added to the NG material data simply by clicking the “mark” toggle button to turn it on. An image object with a mark such as can be added in advance.
[0188]
As a result, it becomes possible to process the NG material data together after the fact (processing that repeats confirmation, adjustment and reconfirmation of each NG material data), preventing unintentional interruption of the preview work, and improving work efficiency. It is possible to obtain a special effect of avoiding the deterioration of the operation and the occurrence of work errors.
The marking operation may be executed not only in the preview operation but also in the filing operation, for example. If you mark material data that you feel uncomfortable during filing, you can check the material data after the fact and take the necessary action.
[0189]
In the above-described embodiment, when performing the post-confirmation and adjustment work for the NG material data, first, the “marked” image object must be found from all the display lines of the data sheet CTL 919a. However, especially when the number of displayed lines is large, the search operation involves considerable difficulty. This is because an image object has a size of several millimeters at most, and a “mark” (a picture imitating a flag) contained in the object is even smaller. Therefore, the above embodiment has room for improvement in terms of improving search accuracy and reducing work fatigue (for example, eye strain) particularly when the number of display lines is large.
[0190]
FIG. 17 is a layout diagram of a form (“extraction condition specification” form 1000) added to the above embodiment with the intention of such a point, and this “extraction condition specification” form 1000 is shown in FIG. The user opens the screen by selecting a predetermined submenu item on the GUI screen 910.
[0191]
In the title bar 1001 of the “specify extraction condition” form 1000, for example, the value of the name property of this form (“specify extraction condition”) is displayed, and a “close” button 1002 is provided at the right end. In the form, a frame line CTL 1004 named “Designation of extraction condition” is provided, and three command buttons CTL 1005 named “Extraction”, “Cancel” and “Help” are provided at the bottom. 1006 and 1007 are provided.
[0192]
Nine list boxes CTLs 1009 to 1017 and three option groups (“execution target”, “search direction”, and “conditional expression”) option groups CTL1018 to 1020 are provided in the “extraction condition designation” frame CTL1004. It has been. Further, two option buttons CTL1021, 1022, 1013, 1024, 1025, and 1026 are grouped and provided in the three option groups CTL1018 to 1020, respectively.
Some of the nine list boxes CTL 1009 to 1017 (three list boxes CTL 1009, 1010, and 1011 named “condition items” in the figure) include “mark extraction” as one of selectable list items. ”Is set, and by specifying“ mark extraction ”of the list item in at least one of the three list boxes CTL1009, 1010, 1011, a mark extraction process described later can be executed. ing. The three list boxes CTL 1009, 1010, 1011 correspond to the second control described in the gist of the invention.
[0193]
Immediately after the “extraction condition specification” form 1000 is opened, the value properties of the nine list boxes 1009 to 1017 are NULL. The option value of the “execution target” option group CTL1018 is “1” (the option button CTL1021 on the left side named “database” is selected), and the option value of the “search direction” option group CTL1019 is “ “NULL” (no option button CTL1023, 1024 is selected), and the option value of the “conditional expression” option group CTL1020 is “1” (the left option button CTL1025 named “AND” is selected). State).
[0194]
Each CTL included in the “designation of extraction conditions” frame CTL 1004 is for designating mark extraction and other extraction conditions (condition items, extraction formulas, extracted character strings, etc.).
[0195]
An “extract” command button CTL 1005 is used to instruct execution of the extraction process, a “cancel” command button CTL 1006 is used to close the “specify extraction condition” form 1000, and a “help” command button CTL 1007 is used to select an extraction condition. This is to display a help document that describes the specification.
[0196]
FIG. 18 is a schematic flowchart of the click event procedure (extraction_Click) of the “extract” command button CTL1005, and in particular, a portion related to mark extraction is extracted.
[0197]
When this procedure is executed, it is determined whether or not the mark extraction is performed with reference to the Value property of nine list boxes 1009 to 1017 (more precisely, three list boxes CTL1009, 1010, and 1011 of them) in step S31. Determine. When the Value property is other than NULL and includes an extraction condition other than “mark extraction”, it is an extraction other than the mark extraction, and therefore, for each CTL included in the “designation of extraction condition” frame CTL 1004 The process proceeds to a separate extraction process (not shown) based on the Value property, but the value properties of nine list boxes 1009 to 1017 (more precisely, three list boxes CTL1009, 1010, and 1011) are “mark extraction”. "Is included, the following" mark extraction process "is executed.
[0198]
First, DB_TBL of the database subsystem 300 is opened at step S32, and a new record set is created at step S33. Next, the record number property of DB_TBL is checked in step S34. If the record number property is a NULL value or 0 (no record), the required error processing (for example, the status area of the dialog or GUI screen 910) is performed in step S35. After displaying an error message at 918), the new record set and DB_TBL are closed in step S42 and step S43, and the procedure is terminated.
[0199]
On the other hand, if the record number property is not a NULL value or other than 0, the process proceeds to step S36, where the first record of DB_TBL is set as the current record (record to be processed), and the mark field of the current record (see FIG. 2) in step S37. It is determined whether the value of True is true, that is, whether or not a mark is added. If a mark is added, the current record is added to the new record set in step S38 (corresponding to the extracting means described in the gist of the invention), and then the current record is advanced one step in step S39. For example, the record addition to the new record set is passed, and the current record is advanced by one in step S39.
[0200]
Next, in step S40, the EOF property of DB_TBL (the EOF property becomes True when it exceeds the last record) is checked. If EOF property = True, step S37 and subsequent steps are repeated.
[0201]
When the EOF property of DB_TBL becomes True, all of the marked records extracted from DB_TBL (records whose mark field value is True) are added to the new record set.
[0202]
Finally, after displaying the data of all the records of the new record set in the data sheet CTL 919a in step S41, the new record set and DB_TBL are closed in steps S42 and S43, and the procedure is terminated.
Note that the above operation on DB_TBL is actually performed indirectly, for example, by generating a SQL command character string. That is, the click event procedure of the “extract” command button CTL 1005 generates a required SQL command character string and outputs the character string to the database subsystem 300. A database engine (SQL server engine) installed in the database subsystem 300 interprets the SQL character string and executes various operations on the above-described DB_TBL.
[0203]
FIG. 19 shows a display state of a data sheet CTL 919a showing the execution result of the procedure. The data sheet CTL 919a displays data included in the new record set. These display data are all the marked records extracted from DB_TBL (records whose mark field value is True), in other words, the marked records (third or third record) from the display records of the data sheet CTL 919a of FIG. 3 image objects 919f and 919g) are extracted.
[0204]
As described above, according to this improved example, the “specify extraction condition” form 1000 is opened, and nine list boxes 1009 to 1017 (more precisely, three list boxes CTL 1009, 1010, 1011) is used to specify “mark extraction”, and by simply clicking the “extract” command button CTL1005, only the marked ones are extracted from all the records of DB_TBL, and the data sheet It can be displayed on CTL 919a.
[0205]
Therefore, only a record of NG material data can be found instantly and reliably from a large number of records, and the inconvenience of the above embodiment can be solved by improving search accuracy and reducing work fatigue. A special effect is obtained.
[0206]
