Description

  The present invention relates to an audio / video information processing apparatus such as a recording / reproducing apparatus or a broadcast / communication receiving apparatus, and in particular, program information such as a program name, a channel, a genre, a required time, a date, a time, and a day of the week together with audio / video information. The present invention relates to a technique for setting a program to be recorded for reservation or received in an audio / video information processing apparatus such as a video disk recording / playback apparatus that receives broadcast or communication information and performs recording / playback.

  Conventional scheduled recording (scheduled recording) settings can be made by browsing program program information such as newspapers and magazines to obtain information such as the day of the week, broadcast time, and channel of the program for which scheduled recording is desired. This is generally done by inputting and setting the time and channel. In addition, a product having a function capable of periodically recording the same program is known, but this is limited to a program in which the day of the week, the time, and the channel can be set to be the same.

As described above, in the prior art, a program to be reserved recording (reserved recording) is searched from program program information such as newspapers and magazines, and information such as day of the week, broadcast time, channel, etc. of the program to be reserved recording is acquired. Since scheduled recording operations were performed based on acquired information, users had to browse program program information such as newspapers and magazines each time, especially broadcast programs that are expected to increase in the future. However, there is a problem that searching for a desired program from program program information such as newspapers and magazines is a very troublesome work for the user. In addition, when there is no newspaper or magazine in the first place, there is a problem that program information such as broadcast time and channel necessary for reserved recording cannot be obtained. Furthermore, scheduled recording of the same program can be performed regularly only when the same day of the week, time, and channel can be set. Otherwise, it was necessary to perform scheduled recording every time. There is also a problem that it is troublesome.

An object of the present invention is to provide an information processing apparatus capable of reserving and recording a program corresponding to a set condition and recording and updating the program on a recording medium .

An information processing apparatus according to the present invention includes a receiving unit that receives a program transmitted by broadcast or communication and program information related to the program, a recording unit that can record the program received by the receiving unit on a recording medium, Reservation recording setting means for setting conditions relating to a program to be recorded on the recording medium by the recording means, and the recording means for recording a program corresponding to the conditions set by the reservation recording setting means on the recording medium And control means for controlling. The control unit overwrites the newly received program when a new program corresponding to the condition is received by the receiving unit after the program corresponding to the condition is recorded on the recording medium by the recording unit. The recording means is controlled as follows. Alternatively, after the recording unit has recorded the program corresponding to the condition on the recording medium by the recording unit, the control unit has already recorded the program corresponding to the condition on the recording medium when the receiving unit has received the program. The recording unit is controlled to erase the program corresponding to the condition from the recording medium and record the newly received program.

According to the present invention, it is possible to provide an information processing apparatus capable of reserving and recording a program corresponding to a set condition and recording and updating it on a recording medium .

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a schematic diagram for explaining the basic concept of one embodiment of the present invention. In this embodiment, as an example of an audio / video information processing apparatus such as a recording / reproducing apparatus or a broadcast / communication receiving apparatus, as shown in FIG. 1, a digital versatile disc recording / reproducing apparatus 1 (hereinafter referred to as a disc recording apparatus). 2 is a digital versatile disc (hereinafter referred to as a disc), which is an information recording medium that is detachably attached to the disc recording / reproducing device 1. Reference numeral 3 denotes a remote controller (hereinafter referred to as a remote controller 3), which is configured as an input / display device including an input operation unit and a display unit. -Manipulate playback operations, input various information, display predetermined information, etc. Reference numeral 4 denotes a display device (hereinafter referred to as a display 4) connected to the disk recording / reproducing apparatus 1, and an output signal of the disk recording / reproducing apparatus 1 is output as video or audio.

In the present embodiment, the remote controller 3 inputs information related to control of the disc recording / reproducing apparatus 1 and recording information. Information relating to the input control and recording information is recorded in the storage unit 16 or the disk 2 to be described later in the disk recording / reproducing apparatus 1, or both the storage unit 16 and the disk 2. Furthermore, as information sent through broadcasting or communication, the program title (program name), channel, genre, required time, date, broadcast time, as well as audio / video information as the program itself such as video, still image, audio, etc. Even when information about the program (program information) such as a band, a day of the week, a performer, or a synopsis is sent, the program information is stored in the storage unit 16 or the disc 2 in the disc recording / reproducing apparatus 1 or the storage unit 16. Recorded on both discs 2. In either case, when the disk 2 is mounted, a code that can uniquely (uniquely) identify the disk 2 is defined, and this identification code is recorded in the disk 2 and the storage unit 16. Of the recorded information, information relating to the loaded disc 2 is associated with the identification code. As a result, when the disc 2 once loaded is remounted in the disc recording / reproducing apparatus 1, a list of programs recorded on the disc 2 and reserved for recording can be displayed.

  FIG. 2 is a block diagram showing the inside of the disk recording / reproducing apparatus 1 in FIG. 1 as necessary function blocks. In the figure, 11 is a central processing unit, 12 is a drive control unit, 13 is a motor, 14 is an optical pickup, 15 is a signal processing unit, 16 is a storage unit, 17 is a display control unit, 18 is a clock signal generation unit, 19 Is a tuner unit, and 20 is an external input / output device control unit. Reference numeral 21 denotes a laser disk device connected to the disk recording / reproducing apparatus 1, and reference numeral 22 denotes a video tape recorder also connected to the disk recording / reproducing apparatus 1.

  The disc recording / reproducing apparatus 1 operates under the control of the central processing unit 11 based on an instruction from the remote controller 3. The optical pickup 14 operates as a signal detector when reading and as a signal recorder when writing depending on the intensity of the laser power.

When reading information from the disk 2, the motor 13 is driven via the drive control unit 12 and the optical pickup 14 is positioned (tracking servo, focus adjustment, etc.). Information recorded on the disk 2 is input to the signal processing unit 15 as a modulation signal from the optical pickup 14, where it is converted into a digital signal and stored in the storage unit 16 of the central processing unit 11. If the information recorded on the disk 2 is audio- video information, it can be displayed directly on the display 4 via the display signal output unit 17 without being stored in the storage unit 16.

When recording information on the disk 2, the motor 13 is driven via the drive control unit 12 and the optical pickup 14 is positioned (tracking servo, focus adjustment, etc.). Information stored in the storage unit 16 of the central processing unit 11 to be recorded on the disk 2 is input as a digital signal to the signal processing unit 15, converted into a modulation signal of the optical pickup 14, and recorded on the disk 2. If the information to be recorded on the disc 2 is audio / video information such as a broadcast program, the disc is directly stored in the disc by the optical pickup 14 via the central processing unit 11 and the signal processing unit 15 without being stored in the storage unit 16. 2 can also be recorded.

  Clock information for knowing the current time used for managing the recording start time and the recording end time is calculated from the clock signal from the clock signal generator 18 based on the frequency and the number of clocks.

The broadcast channel designated for recording is selected by the tuner unit 19, and the received signal is converted into a digital signal by the signal processing unit 15. The audio / video information is recorded on the disc 2, and information on the program is stored in the storage unit 16 and Recorded on the disc 2.

The external input / output device control unit 20 controls the laser disk device 21 and the video tape recorder 22 connected to the outside, and can read and record predetermined audio / video information from these devices. In terms of the system, this is equivalent to an increase in the number of types of broadcast channels, and is realized by designating special channel numbers (for example, L1, T2, etc.).

  FIG. 3 shows an example of dividing the write area for data and management information in the disk 2 of this embodiment.

The recording area of the disc 2 is roughly divided into four areas, a lead-in area 33, a management information recording area 34, a data recording area 35, and a lead-out area 36. In the lead-in area 33, information relating to the physical specifications of the disc is recorded. The management information recording area 34, information about the reservation recording information on recorded audio-video information, such as management information of the data file recorded in the data recording area 35, also in the data recording area 35, audiovisual Data files of information itself are recorded. In the lead-out area 36 which is the last area as a recording area, 0 data is recorded in order to distinguish it from other areas.

  When the disc 2 is loaded, the central processing unit 11 reads the lead-in area 33 and the management information recording area 34 of the disc 2, stores them in the storage unit 16, and manages the data recording area 35.

  Table 1 shows an example of a breakdown of information related to reserved recording and information related to recorded audio / video information recorded in the management information recording area 34.

  The recording start time and recording end time (which can also be specified by a relative time from the start time) are hour and minute recordings, but seconds can be recorded as necessary.

  The recording channel is a tuner built in the disc recording / playback device 1 (not only terrestrial TV tuners, satellite broadcasting such as BS broadcasting and CS broadcasting, digital satellite broadcasting such as digital CS broadcasting, cable broadcasting such as CATV) However, for information from an information medium such as a laser disk device or a video tape recorder, the input port number to which an external device (player or the like) is connected is recorded.

  The title, genre, and detailed information can be recorded by using information related to audio / video information transmitted by being superimposed on audio / video information in addition to a method in which the user directly inputs information using the remote controller 3 and records the information. There is a case. Here, the latter case will be described. In this case, there are two recording methods.

  In the first method, information related to a plurality of audio / video information to be transmitted while being superimposed on audio / video information is displayed on the display 4, arbitrary audio / video information is selected by operating the remote controller 3, and the selected audio / video information is displayed. Is a method of recording information on the disk 2 or the storage unit 16.

  In the second method, when the date, time, and channel of the audio / video information to be recorded are input using the remote controller 3, the input information and the program information transmitted by being superimposed on the audio / video information are logically calculated, and the corresponding date is calculated. In this method, the program information of the time and the channel is searched, and the corresponding title, genre, and detailed information are recorded on the disc 2 or the recording unit 16.

  The first method is effective for the reservation recording operation using the program table displayed on the display 4, and the second method described above is to input only the date, day of the week, time and channel, and make a reservation. This is effective when recording. In any case, the list of recorded and reserved recording programs displayed on the display 4 by mounting the disk 2 in the disk recording / reproducing apparatus 1 can be displayed with the same contents.

  The end time, the interruption start time, and the interruption end time may be recorded as relative time from the start time.

In the present embodiment, the recording interruption at the time of recording is set, but it is also possible to record the reproduction interruption at the time of reproduction or skip reproduction. The interruption at the time of reproduction may be set by the user judging the reproduction information. However, when the interruption information is mixed in the reproduction information, the interruption information is used for the reproduction interruption start time and the reproduction interruption end. Time can also be recorded. From the user's point of view, the reproduced information is equivalent as a result, whether it is interrupted during recording or interrupted during playback (skip playback).

  The management information related to the recorded data and the reservation record information are organically combined, and can be displayed independently or in combination.

  Specific examples of displaying management information related to recorded data and reservation recording information on the display 4 using management information stored in the disk 2 or the storage unit 16 are shown in FIGS. 4, 5, and 6, respectively. .

  FIG. 4 shows an example of displaying a list of already recorded data, and FIG. 5 shows an example of displaying a list of data scheduled to be recorded in the future by reserved recording. FIG. 6 is an example in which FIG. 4 and FIG. 5 are combined and displayed as a list.

  In any case, the case where the data number, classification, recording start time, recording end time, title, genre, recording area, recording capacity, etc. are displayed is shown as an example. In FIG. 6, areas No. 3 to No. 8 represent reservation information display areas.

  The designation items in the classification information column include date designation, day designation, title designation, and condition matching designation, but the subsequent operations differ depending on the type of the designation item. In other words, if a recording reservation is made by specifying a date, if the recording is performed once at the corresponding date and time, no recording is performed thereafter. However, if a day of the week is specified, recording is continued every week at the same time. If the day of the week is specified from Monday to Friday, excluding weekends, it is processed as an extended designation of the day of the week. That is, in this case, processing is performed as when five days of the week are designated. Although not shown in the figure, in the case of daily designation, recording is continuously performed every day (7 days from Sunday to Saturday) every day at the same time. Note that the title designation and the condition matching designation are limited to cases where program information superimposed on audio / video information can be used. In title designation, information related to audio / video information is read at a predetermined timing, and only audio / video information that is the same as or included in the title in the title column is sequentially recorded. Similarly, in the case of condition matching designation, only the audio / video information that satisfies the conditions is sequentially recorded.

  In FIG. 5, when the recording area is “new”, it indicates that when a program received based on the reservation information is recorded on the disk 2, an unrecorded area is allocated as the recording area of the disk. If there is no unrecorded area, a message such as "Disk is full" is displayed, and the operation to erase the data in the already recorded area is performed until the reserved program reaches the recording capacity. It is necessary to enlarge the unrecorded area.

  In FIG. 5, when the recording area is “replacement”, program information such as a program name (program title), channel, genre, required time, date, time, day of the week, etc. sent from the satellite digital tuner is read. The program that is broadcast most recently is searched, stored as reserved recording data, and over-recorded (overwritten) in an area that has already been recorded at the same time, the same time, and the same channel. If there is no corresponding area, a message such as “The program is a new program” is displayed, and it is selected whether to cancel (cancel) or continue. In the case of continuing, an operation to change to new registration is performed.

  In addition, in the example of FIG. 6, an expected state at the time when all the reserved recordings (reserved recordings) are completed is shown. However, by designating an arbitrary date and time, the progress status of the reserved recordings at that time can also be indicated. .

  Further, reservation recording can be performed by the following method using the display screen of FIG. For example, No. 3 is selected from the screen in the figure, the classification field is changed to the title, and the recording area is changed from “recorded” to “replacement” or “new”. This change is performed by operating the remote controller 3 while viewing the display screen of the display 4, and information input by the remote controller 3 is transmitted to the central processing unit 11 and further recorded on the disk 2 or the storage unit 16. The central processing unit 11 compares the title and information related to the audio / video information at a specified interval, and automatically records the audio / video information when the titles as keywords match or are all included. In addition to this automatic recording, there is a method in which information related to audio / video information available at the time of operation is used to display a list of corresponding audio / video information on the display 4 and selected by the remote controller 3 to confirm the reserved recording information. is there.

In addition, reservation recording can be performed by the following method using the display screen of FIG. Make the classification field a condition match. Next, enter one or more keywords such as program series (title), genre, performer, etc., and search conditions such as channel, day of the week, time zone, etc., and specify logical conditions with AND or OR. . This designation is performed by operating the remote controller 3 while viewing the display screen of the display 4, and information input by the remote controller 3 is transmitted to the central processing unit 11 and further recorded on the disk 2 or the storage unit 16. The central processing unit 11 compares the condition specified at the specified interval with the information related to the audio / video information, and automatically records the corresponding audio / video information when all the conditions match. In addition to this automatic recording, there is a method in which information related to audio / video information available at the time of operation is used to display a list of corresponding audio / video information on the display 4 and selected by the remote controller 3 to confirm the reserved recording information. is there.

  Needless to say, when the condition matching is specified using the display screen of FIG. 5, the search condition input to the title column may be only one or a plurality of keywords that can narrow down a specific program to some extent. . In addition, when performing title designation using the display screen of FIG. 5, it is also possible to input a plurality of titles as keywords and designate logical conditions by AND or OR.

  FIG. 7 shows an example of a condition input screen display in the case of a condition match, and FIG. 8 shows a processing flow for setting a reservation record for a condition match.

First, the disk recording / playback apparatus 1 and the display 4 are turned on (step 801), and the keyword of the program to be reserved for recording and other search conditions and logical search conditions are input (input reservation condition information) by the remote controller 3 (step 802). ), The reservation information is written in the storage unit 16 (step 803). Next, information related to the audio / video information such as the program name, channel, genre, required time, date, time, day of the week and the like, which is transmitted superimposed on the audio / video information, is read (step 804), and the storage unit 16 is subjected to the processing of step 802. The stored information and logical operation are performed to search for the corresponding program (step 805). At that time, if the corresponding program cannot be searched, the reservation condition information is input again in step 802 and the search is performed again, or the process is terminated when the power is turned off (step 810). If a corresponding program is found, a list of the corresponding programs is displayed in step 806, a program is selected in step 807, and execution or non-execution of reserved recording is performed in step 808 (whether or not to set reserved recording). In the case of determination and non-execution, the reservation condition information is input again in step 802 or the process is terminated when the power is turned off (step 810). On the other hand, if it is determined in step 808 that the reserved recording is to be executed, the program information of the selected program is written in the storage unit 16 as the reserved recording information (step 809).
When the power of the display 4 and the disc recording / reproducing apparatus 1 is turned off (step 810), a transition is made to a standby state for reserved recording (reserved recording).

  As described above, in addition to the selection method using the program information obtained at the time of the reservation operation, the reservation operation may be terminated at the stage of step 804 to enter the reservation recording standby state. In this case, program information is read at an appropriate timing, a logical operation is performed based on the reservation condition information input in step 802, the corresponding program is searched, and the corresponding program is automatically recorded.

  FIG. 9 shows a processing flow for setting reservation recording with the same title.

In step 901, the disc recording / playback apparatus 1 and the display 4 are turned on. In step 902, for example, a list of program information recorded on the disc 2 is displayed on the display 4 by operating the remote controller 4. Next, when the title of the program to be reserved for recording is selected by operating the remote controller 4 in step 903, this is written in the storage unit 16 (step 904). Next, information related to the audio / video information such as the program name, channel, genre, required time, date, time, day of the week, and the like, which is transmitted superimposed on the audio / video information, is read (step 905), and the title specified in step 903 is read. A program with the same title is searched (step 906). When the corresponding program is searched, the program information related to this program is written in the disk 2 or the storage unit 16 as the reserved recording information (step 907). If the corresponding program cannot be searched, the reservation record information is not recorded. Even after the power is turned off (step 908), the disc recording / playback apparatus 1 reads the program information relating to the audio / video information at the specified interval (step 905), and searches for the program having the same title as the title specified in step 903. (Step 906). At that time, when the corresponding program is searched, it is written in the disc 2 or the storage unit 16 as the reservation record information in the same manner as described above.

  In addition, when setting reservation recording by using information related to audio / video information that is available at the time of operation, a program list of the corresponding title is displayed on the display 4 after step 906, and the remote controller 3 is displayed. The program to be reserved and recorded is selected / determined, and the program information relating to the selected program is written to the disk 2 or the storage unit 16 as the reserved recording information, thereby completing the reservation recording input operation.

  FIG. 10 shows a display example that lists program information searched after an input operation in a condition-matching reservation record, and FIG. 11 shows a display example that lists program information searched after an input operation in a reservation record of the same title. Each is shown.

  In the above-described embodiment, the disk recording / reproducing apparatus (digital versatile disk recording / reproducing apparatus) 1 has been described as an example of the audio / video information processing apparatus. However, the present invention uses various recording media other than the digital versatile disk. Needless to say, the present invention can be applied to a recording / reproducing apparatus or various broadcasting / communication receiving apparatuses. Furthermore, the present invention can be applied not only to reserved recording (reserved recording) but also to reservation reception without recording depending on circumstances.

In addition, information related to audio / video information has been taken as an example when it is superimposed on audio / video information, but what is important is the content of the information. If the information is related to audio / video information, such as a floppy disk or a CD-ROM. It goes without saying that the present invention can be applied regardless of what means is input from another medium.

  Furthermore, it goes without saying that information read after the recording date and time can be displayed in the same manner by performing the same processing as the information obtained before the recording date and time. This process is effective when the broadcast schedule changes suddenly or when it is supplied on a CD-ROM or the like.
