2. Description of the Related Art As a conventional centralized management karaoke system, a video karaoke signal is temporarily converted into a television signal by a frequency modulator other than a general television broadcast, and then a request terminal in each room is used by using a joint viewing line. , And demodulates the original video karaoke signal using the request terminal (CATV system, etc.). As an example of this, a plurality of karaoke players with video are collected and controlled in one place, and for each karaoke player with video, a frequency modulator other than general television broadcasting is attached and a joint viewing line is used to control terminals. There has been a system in which a central control device designates a reception frequency of a device via an auxiliary control device and receives it (Japanese Patent Application Laid-Open No. 63-6994, "Karaoke centralized management system with video and its device").

[0003]

By the way, the above-mentioned centralized karaoke system of the related art is effective when a joint viewing line is constructed, but it is effective when the joint listening line is not constructed. When a centralized karaoke system is adopted, it is first necessary to construct a joint viewing line having frequency modulators corresponding to the number of request terminals (the number of karaoke reproduction signals). As a result, this system is constructed. There is a problem that a large initial investment is required in order to do so.

[0004] Further, when the basic system once constructed is reduced (when the number of request terminals is reduced), some of them are not used for the frequency modulator.
As a result, there is a possibility that a problem that the utilization efficiency of the basic system is reduced may occur.

[0005] Furthermore, since the video karaoke signal is once converted into a television signal by a frequency modulator other than general television broadcasting and then sent to the request terminal in each room using a joint viewing line, the line karaoke signal is not transmitted. Signal degradation such as adjacent channel interference and signal attenuation due to a long route of a line cable requires a great deal of adjustment to improve this and to transmit a high quality video signal.

The karaoke reproducing apparatus 2 (21 to 23) has an MP
This is a disk autochanger which can use both EG and CD-G standard karaoke disks (for example, Japanese Patent Application No. 157407/1992 "Karaoke reproducing apparatus" proposed by the present applicant). The video and audio performances of the MPEG standard karaoke disk reproduced here conform to the MPEG1 standard.

The karaoke reproducing apparatus 2 (21 to 2)
In 3), a large number (for example, 360) of karaoke disks stored therein are selected according to the user's selection of the tune, and can be reproduced. This disc contains a large number of songs (up to 18 songs, 74
Video data of moving images, two-channel audio, and data related to the song (disc number, software number, song title, singer name, etc.) are recorded for each minute. Is reproduced and output as needed. Also, CD-G disks can be stored as disks of different types as described later.

The karaoke reproducing apparatus 2 (21 to 2)
3) mainly comprises a changer mechanism section, two player sections, and a controller (all are not shown).

The changer mechanical section includes a changer controller and a communication module, and the player sections each include a player controller. The above-described controller includes a remote control receiver.

Next, the karaoke reproducing apparatus 2 having the above configuration
The reproduction operation (21-23) will be described. First, the karaoke playback device 2 (21 to 21) is transmitted from the central control device 3 described above.
In response to the request 23), a control signal (reproduction drive control signal described later) for reproducing the disk corresponding to the software number associated with the requested music is supplied via the data line 13.
In response to this, the controller of the karaoke reproducing apparatus in which the disk containing the requested music is stored temporarily stores the software number of the requested music. In parallel with this operation, based on the built-in software number / disk number comparison data, the disk number of the disk in which the music number of the selected software number is recorded is searched.

In response to this search result, the disk of the disk number is stored in any part (shelf) in a disk disk tray (not shown) based on the built-in disk number versus disk storage part address number comparison data. To find out what is. Based on the search data obtained in this way, a drive control signal for removing the disk stored in the storage part with the address number is output from the controller to the changer mechanism. At the same time, a response signal indicating that the disk related to the requested music is specified is output to the central control device 3.

The changer controller of the changer mechanism controls the drive of a disc carrier (not shown) as follows based on the applied drive control signal. That is, the disk carrier is changed from the standby state to the driving state,
First, the disk is transported at a high speed toward the storage portion where the disk is stored. When the disk approaches the storage portion, the disk is transported at a low speed, and when the disk reaches the storage portion, the disk is stopped. Thereafter, when the disk stored in the storage portion is taken out and mounted on the mounting portion of the disk carrier, the disk carrier changes from a stopped state to a driving state, and the disk is transported at high speed toward the player section. . Thus, the disc is placed on the turntable (not shown) of the player section. Thereafter, the disk carrier enters the standby state again.

Prior to the above-mentioned case, the controller recognizes that a disc is not placed on any of the player sections, and in that case, sends a control signal indicating that discs are placed in any of the player sections in this order. Of course, the output is output to the changer controller of the changer mechanism.

Thereafter, a control signal for reproducing the disk corresponding to the software number corresponding to the requested music is transmitted from the centralized control device 3 to the karaoke reproducing device 2 (21 to 23) via the data line 13. When supplied, the disk in which the requested music is recorded can be placed on a turntable (not shown) of the player section by the same operation as described above. The player controller of the player section outputs a rotation control signal for rotating the turntable on which the disc is mounted at a constant linear velocity to a motor (not shown). At the same time, a response signal is output to the central control device 3 indicating that the disk related to the requested music is in a reproduction standby state. As a result, the motor changes from the stop state to the constant speed rotation state, and rotates the turntable at a constant speed. In this state, the disk is reproduced and scanned by an optical pickup (not shown) to output a reproduced data signal.

In this manner, a series of reproduced data signals having the above-described structure (a karaoke software data signal described later,
A character / symbol code signal, a video signal, and an audio signal that are not decompressed (decoded) are supplied from the player unit to the communication module of the changer mechanism unit via a data bus line. After being converted into a communication format conforming to RS-422, which is a standard serial interface specification, the data is supplied to the central control device 3 via a maximum of 18 data lines 14 to 16.

The above-mentioned MPEG1 standard is a CD-
To ensure compatibility with ROM disks, the read rate of the data-compressed digital video signal is set to 1.15 Mb / s and the data is compressed to satisfy the data transfer rate (read rate) of 1.5 Mb / s. The read rate of the audio signal is set to 0.224 Mb / s, and both of the data-compressed signals are time-division multiplexed and output at a read rate of 1.39 Mb / s. s. The reason is that the upper limit frequency of the video signal is set to 4.2 MHz, and the read rate of the digital video signal which is not subjected to A / D conversion and data compression is 100 Mb.
/ S is required, and the upper limit frequency of the audio signal is set to 20 kHz, and the read rate of the digital audio signal which is not subjected to A / D conversion and data compression is 1.4M.
Since b / s is required, the read rate of a signal obtained by time-division multiplexing these two signals is 101.4 Mb / s, which greatly exceeds the read rate of 1.5 Mb / s. This is because the disk specification cannot be satisfied. Therefore, by compressing the data, the data compression rate of the digital video signal becomes 1/87 and the data compression rate of the digital audio signal becomes 1 / 6.3. The above-mentioned karaoke disk (hereinafter, sometimes referred to as a disk) formed by a board making technique corresponding to a well-known CD-ROM disk mainly includes a plurality of karaoke software, and is arranged in the order of music pieces.

<Functions of Central Management Karaoke System> Now, various functions of the central management karaoke system 1 having the above configuration will be described.

1. [Mode setting of request terminal device 7] When the request terminal device 7 is polled from the central control device 3 via the multi-cable C, the request terminal device 7 always returns a response if the power is on (the command to be sent is If not, an acknowledgment (ACK, Acknowledge) is returned). When the power of the request terminal device 7 is turned on and a response is returned to the centralized control device 3, the centralized control device 3 performs system setting by the above-described application program software (basic software) read from the floppy disk FD # 1 via the FDD. A mode setting command corresponding to this is sent to the request terminal device 7.

The request terminal device 7 can set the following items (1) to (7) with this mode setting command. (1) Number of digits of song selection number (song number) (5 digits / 6 symbols) (2) Performance start mode (automatic / manual) (3) Re-songable time (seconds) (4) (food and drink) order Function availability

When the guest room management system 5 is connected to the central control device 3, the following items can be additionally set. (5) Series names (genre names) that can be selected (6) Permission / prohibition of music selection (7) Clearing of music selection memory, etc.

2. [Song Selection / Kanji Song Name Display] When the request terminal device 7 receives the mode setting command sent from the central control device 3, the request terminal device 7 can select a song from the request terminal device 7 main body or the remote controller 12. The selected song numbers can be stored in a memory inside the request terminal device 7 up to a maximum of eight songs.

When the request terminal device 7 is polled by the central control device 3, the request terminal device 7 sends a request command which is music number data to the central control device 3. As described above, the central control unit 3 converts all the song name data (each data relating to the shelf number table and the song name table) and the kanji song name data recorded on a large number of disks in the karaoke reproducing device 2 into the I / F sections are stored in the second and third memory sections, respectively. Then, upon receiving a request command from the request terminal device 7, the centralized control device 3 performs a song number-shelf number conversion process and a song title search transmission process in accordance with the above-mentioned basic software. That is, it searches for kanji tune name data corresponding to the tune number corresponding to the request command, and sends the kanji tune name data for the requested tune obtained by the search to the request terminal device 7.
As a result, the kanji tune name data arrives at the request terminal device 7, and after performing necessary signal processing, the kanji tune name related to the request can be displayed on the monitor 8, whereby
Request songs can be confirmed in kanji display.

3. [Optimization search / scroll] A plurality of players 17 in the karaoke reproducing apparatus 2 can supply the karaoke software data signal of the requested music to the request terminal device 7 in the shortest time and quickly reproduce the requested music. Is controlled to be used most efficiently. If a request for the same song happens to be issued from a plurality of request terminal devices 7 and the simultaneous playback process of the same song cannot be performed in the karaoke playback device 2 storing the disc, the request terminal device 7 relating to the later request
Is changed, and control is performed so that the next tune enters the performance standby state first (scroll operation).

4. [Performance Start] When the requested music is in the performance standby state, the standby status response status is transmitted from the karaoke reproducing apparatus 2 in the standby state to the requesting terminal device 7 via the central control device 3. After receiving the status, the request terminal device 7 selects the performance start mode of the mode setting described above, and then sends a performance start command to the central control device 3. Upon receiving this, the central control unit 3 outputs the output (the karaoke software data signal) of the disk player 17 in which the disk of the requested music is placed in the karaoke reproducing apparatus 2 and is in a performance standby state.
Switches the built-in matrix switcher so that it can be supplied to the request terminal device 7 that made the request, and then switches the disk player from the standby state to the playing state.

5. [Re-song] In this way, when the performance of the requested song has started, but the user who sings along with the song fails to start singing, the beginning of the song is limited to a certain time (for example, 40 seconds after the start of the performance) from the beginning of the request song. You can sing again from When the “start (restart start) / S key” of the request terminal device 7 is operated, the request terminal device 7 outputs a re-song request command to the central control device 3. In response to this, the central control device 3 sends a control signal to the playing karaoke reproducing device 2 to the beginning of the music being played again and automatically start playing to the playing disk player 17. As a result, the disc player 17 temporarily stops the performance of the music and then returns to the performance state from the beginning of the music. The setting of the resongable time is performed by the above-described mode setting command from the central control device 3 to the request terminal device 7.

6. [Pitch Adjustment] The pitch adjustment is possible at the time of reproducing both the MPEG and CD-G discs, and the pitch of the audio signal reproduced from the request terminal device 7 can be processed on the mixing amplifier 9 side.

7. [Speed adjustment] It is possible only when playing a CD-G disc. By operating the "speed control button" of the request terminal device 7,
This command is received by the central control unit 3, and the central control unit 3 sends a control signal for adjusting the playing speed to the playing karaoke apparatus 2 to the disc player 17 in the playing state. The speed of the disk player 17 during the performance can be changed by ± 8%.

8. [Interruption music selection] When music selection is performed by operating the "interruption key" of the request terminal device 7 in a state where some music selections have already been made, music selection is preferentially performed. That is, the tune for which the interrupt selection has been performed is input as the next tune, and the subsequent tunes are moved down. For example, the reservation status before the interruption is the song number “0010” of the first song.
In the case of “1” during performance (state a), the next song number “02306” standby,..., The “interruption key” is operated in the above state (a), and the interrupted song number “04701”
Is input, the reservation status after the interruption is that the song number “00101” of the first song is being played, but when this performance is completed, the song number “02306” of the next song that was previously on standby
Is not played after this, and the music number “04701” of the interrupted music is set as a search state as the next music. As a result, the performance number of the next music number “02306” is lowered by one.

9. [Cancellation of music selection] Request terminal device 7 reserves music that has not been played yet.
Can be canceled by operating the "reservation confirmation key". Reservation for the next song or later can be canceled.

10. [Release Performance] The currently playing music is “Release Performance /
The operation can be stopped at any time by outputting a performance release command to the central control device 3 by operating the "R key". Whether or not this performance release command has been accepted is confirmed by the response status from the central control device 3 to the request terminal device 7. If there is a reservation for the next song, the request terminal device 7 increments the song number stored in its internal memory by one, and if it is on standby, the central control device 3 performs any of the performance confirmation / pause (standby). Is a karaoke player 2
(By default).

[0114] 11. [Preview of Next Song / Waiting Message Display] When the currently playing song approaches the end, the status from the currently playing karaoke reproducing device 2 is sent to the requesting terminal device 7 via the central control device 3. At this time, the request terminal device 7 displays a preview of the next song in the “next performance number / song selection number display section”. If it is not possible, a message "Please wait" is displayed on the monitor 8 while the performance becomes possible after the performance.

12. [Order of food and drink] When the highest digit of the number of digits of the music selection number to be specified is "9",

14. [Addition / Deletion of Disk] The central control unit 3 counts the request frequency (request frequency) for each disk / song name, and based on this count data, determines whether the number of frequently-used disks should be added or not. It is determined whether there is no change in the request waiting time even if the number of disks that are hardly requested is reduced, and the result is displayed on the screen of the monitor 4. In addition, if the karaoke player 2 is to be added,
Which disk tray (shelf) is best stored can be displayed.

[0119] 15. [Connection with Center Computer 5a] In the case of a centralized karaoke system using the above-mentioned guest room management software read out by reproducing the FD # 3 loaded in the FDD connected to the center computer 5a of the guest room management system 5, the guest room management system 5 can be operated as follows.

19. [BGV Function] The playback of the video disc player 13 in the guest room B is controlled by the request terminal device 7, and is used as a BGV (background video) transmission player when playing a CD-G disc. The chapter to be played as the BGV is determined by the tune data supplied from the request terminal device 7 at the time of the request and the genre data such as enka / pops, and the request terminal device 7 selects the optimal video.

<Control of Centrally Managed Karaoke System> Next, specific control of the centralized karaoke system 1 having the above-described configuration and function will be described.

[0125] 1. Shortest waiting time control The central management karaoke system 1 designed in consideration of the usage efficiency, when any one of the request terminal devices 7 is using the karaoke reproducing device 2 and the central control device 3 (during request), Even if another request terminal device 7 is operated to request a song of a disc stored in the shelf of the karaoke playback device 2 in use, the request is not made until the reproduction of the request song of the previous request terminal device 7 is completed. There is a possibility that the reception of the file may be stopped and the reproduction thereof may be kept waiting. Therefore, it is desirable to minimize the probability of waiting, and to minimize the waiting time even in the waiting state. To achieve the shortest waiting time, the following should be performed.

First, the centralized karaoke system 1 from the request until the requested music (karaoke software data signal) is transmitted to the request terminal device 7
A brief description of the operation state of the system will be given.

As shown in FIG. 7, terminals 1'A to 1 '
N (corresponding to each of the request terminal devices 7 described above), the user's request input via the transmission path 2 '(corresponding to the signal path C) is transmitted to the I / F unit 31' (the central control unit 3 described above). The request is transmitted to the request processing unit 32 ′ (corresponding to the control unit configuring the centralized control device 3) via the corresponding I / F unit. In response to this, the request processing unit 3
Reference numeral 2 ′ denotes a music information storage unit 33 (via the I / F unit 31 ′) that stores a disk on which the requested music is recorded.
′ (Corresponding to the above-mentioned karaoke reproducing apparatus 2), a plurality of music information output sections 33′a to 33′m (a plurality of disc players 17 built in the karaoke reproduction apparatus 2).
Are searched for the presence or absence of the use state (the presence or absence of the disk reproduction state). Thus, the request processing unit 32 '
Are not in use (empty) music information output units 33'a-3
When 3'm is searched, a music information output command to reproduce and output a disk related to the requested music using one free music information output unit is sent to the music information storage unit 33 'via the I / F 31'. To be transmitted. Upon receiving the music information output command, the music information storage unit 33 'takes out the corresponding disk corresponding to the requested music from the shelf on which a large number of disks are stored, and conveys the disk to the designated empty music information output unit. Here, the reproduction is started.

As a result, the karaoke soft data signal relating to the requested music reproduced from the designated music information output unit via the I / F 31 'is transmitted to the terminal requesting the requested music via the transmission path 2'. Transmitted, and the terminal can reproduce the requested music (video and audio) using the monitor 8 and the speaker 10.

By the way, all the terminals 1'A to 1'N are receiving the music information reproduced from the music information output units 33'a to 33'm, and all the terminals 1'A to 1'N are receiving the music information. The following processing will be described on the assumption that the request for the next song has already been transferred to the request processing unit 32 '.

Here, the music information output units 33'a to 33 '
The number of m is n <m, 2n> m (where n is the number of terminals 1'A to 1'N, m is the number of music information output units 33'a to 33'm capable of simultaneously outputting music information) ).

In this case, it is possible to allocate (mn) music information output units 33'a to 33'm for waiting for a request for the next music, but from any terminal 1'A to 1'N Is different depending on whether the request is assigned first for standby or not until the song being played ends and the next song is played. For example, a request for the next song from the terminal 1'A to 1'N which has issued a request for a request song whose remaining time is extremely long among the request songs currently being reproduced is preferentially accepted, and music information output is performed accordingly. Part 33'a-3
If 3'm is in the priority standby state, the waiting time from the end of the currently playing requested song to the playback of the next song becomes extremely long.

Therefore, the request processing section 32 'periodically searches for the remaining reproduction times of the music information output sections 33'a to 33'm being reproduced, and the music information output sections 33'a to 33'm to minimize the remaining time. This is assigned to 33'm for waiting for the next song request. If this allocation control is repeated, the vacant music information output unit 33'a is simply executed in the order of requests.
The waiting time until the start of reproduction of the requested next song can be reduced as compared with the control of assigning ~ 33'm.
In this way, in the centralized management karaoke system 1 designed in consideration of the usage efficiency, the probability of waiting can be minimized, and even if the user enters the waiting state, the waiting time can be minimized.

The centralized karaoke system according to the present invention described here is the same as the centralized karaoke system 1 shown in FIGS. 1 and 2 except that m> n (n: terminal devices 1A 'to 1N'). , Karaoke player 21
Music information output unit 33'a capable of simultaneous output of the information
数 33′n), the centralized control device 3 uses the music information storage unit (mn) to use the (mn) music information output units 33 ′ a to 33 ′ n for waiting for the request again. This is a system for controlling a karaoke playback device 33 '.

2. Priority setting control (VIP terminal designation control) As described above, the probabilities of waiting are determined by the terminals 1'A to 1'N.
Priority (order in which the remaining playback time of the requested song is small)
, The higher the priority of the device that does not take much time to play the requested song, the less likely it is that the device with the lower priority will have to wait,
Also, by utilizing such a fact, the fee system can be set according to the priority so that the fee for making a request using the highest priority terminal having the lowest waiting probability is the highest.

Next, a description will be given of a case where a request is made using a terminal having a low waiting probability and a high request priority (a so-called VIP terminal). The same components as those described above are denoted by the same reference numerals, and description thereof will be omitted.
In the above-described normal information flow from the request until the music (karaoke software data signal) is provided, all the terminals 1'A to 1'N are receiving music information, and all the terminals 1'A to The following processing will be described on the assumption that the request for the next song from 1′N has already been transferred to the request processing unit 32 ′.

As shown in FIG. 8, the priority terminal designation for designating the so-called VIP terminal is performed before the request can be started from the terminals 1'A to 1'N by the input unit 35 '.
(Corresponding to the panel keyboard unit constituting the centralized control device 3) to monitor the above-mentioned monitor 4, and to register “room information (operation setting)” on the system setting screen of the centralized control device 3 ( Music selection, VIP) "menu, and then select a terminal to be specified as a priority terminal by selecting" V
Designate as “IP terminal” (enter the request terminal device symbol). Thus, the designated "VIP terminal"
The data is stored in the priority terminal table 34 '(I / F constituting the centralized control device 3) included in the above-mentioned "room management software".
(In the system information storage area in the first memory of the unit).

When there is a request from this VIP terminal,
Upon receiving the request, the request processing unit 32 ′ sends the request to the I / F unit 31 ′.
When the above-mentioned vacancy is detected in the music information output units 33'a to 33'm via the terminal, the priority terminal table 34 'is first referred to, and a request for the next song of the VIP terminal is made. Music information output units 33'a-3 available for request waiting before the next song request
3'm. Thereafter, the same processing is performed for all the terminals 1'A to 1'N, and then the free music information output unit 33
Terminal 1 with the least remaining time for 'a-33'm
'A to 1'N are assigned. As a result, the waiting time of the VIP terminal can be shortened by the priority setting control as compared with the waiting time of other VIP terminals.

As described above, the centralized karaoke system according to the present invention is different from the centralized karaoke system 1 shown in FIGS. 1, 2 and 7 in that the centralized control device 3 has a specific terminal device. The music information storage unit (karaoke playback device) 33 'is controlled so that the (mn) music information output units 33'a to 33'n are preferentially used for waiting for a request from the (VIP terminal) again. It is a centralized karaoke system characterized by the following.

Thus, in the centralized management karaoke system 1 designed in consideration of the usage efficiency, the waiting probability is controlled in accordance with the priority of the terminal, and the terminal having a higher priority is assigned to a terminal having a lower priority. The waiting probability is not high, and for example, the fee can be set according to the priority.

3. Disk Block Reduction Control In the centralized management karaoke system 1 designed in consideration of usage efficiency, a disk on which a frequently requested song (popular song) is recorded is stored in a plurality of terminals 1'A to
The probability of simultaneous requests from 1'N is high. Therefore, in order to promptly and efficiently respond to the user's request, a plurality of frequently requested disks are prepared and the same music is simultaneously requested from a plurality of terminals 1'A to 1'N. Must reduce the probability of disk blocks colliding with each other. However, at present, in order to reduce the probability of occurrence of disk blocks (or blocking), the required number of disks with a high request frequency can only be calculated finely for each disk. I have decided.

In order to suppress the probability of occurrence of disk blocks, it is only necessary to add a plurality of disks of the same type. The more frequently requested disks are added, the lower this risk factor becomes. Doing so will reduce economic efficiency. Therefore, in the centralized management karaoke system 1, it is necessary to know the required number of disks in order to suppress the risk of occurrence of disk blocks on each disk to a certain value or less (for example, 1% or less) and to increase economic efficiency. There is a need for a calculation method. here,
It is necessary to set the value of the risk factor at which a disk block occurs in each disk in consideration of the system cost, the range that the user can endure, and the like. However, the value of the risk factor is provisionally set to 1% or less.

Next, a description will be given of a method of calculating the number of disks that can keep the risk of occurrence of disk blocks on each disk below a certain value (prescribed value). The same components as those described above are denoted by the same reference numerals, and description thereof will be omitted.

As shown in FIG. 9, a request processing unit 32 'for receiving a request is a database unit 34'.
A (a data area in which data corresponding to all songs stored in the request shelf number table and the song name table stored in the second memory in the I / F unit included in the central control device 3 and the history data can be recorded) And the music information output unit 33 of the music information storage unit 33 '.
The music numbers reproduced from the requests' a to 33'm based on the request are monitored. When a disk block occurs, the request processing unit 32 'increments the disk block counter of the disk by one to collect the history of the disk, and this count value is stored in the history data area in the database unit 34'A. Will be recorded.

The statistical processing section 35 '(corresponding to the control section constituting the centralized control device 3) has the number of times of use for each disc recorded in the history data area of the database section 34'A,
Perform statistical processing from the number of disk blocks per disk,
Calculate the expected value of the disk block risk ratio for each disk. Here, the number of performances for each disc is used as information for statistical processing. It goes without saying that the information on the number of times of performance is stored in the database section 34'A.

Here, the calculation method of the specified value of the risk factor of the disk block of each disk is as follows. The number of terminals is k, and the frequency of use of the disk A is ρ. Now, when all the k terminals are playing (assuming the worst), the probability μ _{s of} playing s discs (s <k) of the disc A is represented by μ _m = kCs using a binomial distribution probability formula.・ Ρ ^s (1-ρ) ^k−s ……………………… (1) Therefore, when j disks A (j <k) are prepared, the risk factor λ _j of the disk blocks of the disk A is λ _j = μ _{j + 1} + μ _{j + 2} +... + Μ _k−1 + μ _{k = 1- (μ 0 + μ 1} + ··· + μ j-1 + μ j) ....................................... (2 expression) and the expression (1), (2 type) Thus, the frequency of use of the disk in which the risk factor of the disk block exceeds 1% with respect to the number of terminals and the number of disks is obtained. Here, the frequency of use of the disk is represented by the frequency of use of the disk = (total number of times the same type of disk is played) /
(Total number of performances).

The calculated value and the database unit 34 determined in advance in consideration of the economic efficiency and serviceability.
'A is compared with the set value (1%) of the disk block risk ratio recorded in A, and for each disk, the minimum number of disks for which the expected value of the disk block risk ratio does not exceed the set value of the disk block risk ratio is determined. calculate. Statistical processing unit 3
At 5 ', the minimum number of disks calculated for each disk is transferred (via the I / F unit 31') to the display unit 36 '(corresponding to the monitor 4 described above). The display unit 36 'receiving this information from the statistical processing unit 35' displays the required number of disks. Finally, the system administrator monitors the minimum required number of each disk displayed on the display unit 36 ', compares it with the number of each disk currently stored in the music information storage unit 33', and To add or delete the corresponding disk.

The database unit 34A 'for updating and recording the data of the number of times of music requested by the user and the number of disk blocks of each disk is described above.
A statistical processing unit 35 'for calculating the probability of occurrence of a disk block on each disk by using a statistical processing method on these data;
A display unit 36 'for detecting whether or not the probability of occurrence of a disk block calculated by the statistical processing unit 35' exceeds a specified value and displaying the detected information; and a request processing unit 32
'Has been described.

Next, the central management karaoke system 1 uses the database unit 34 to store information on the number of disks of the same type currently stored in the music information storage unit 33 '.
, An input for inputting a change value of the database unit 34A 'and a detection unit 37' for comparing the number of disks calculated from the statistical processing unit 35 'and detecting that it is necessary to add or delete a disk. The centralized karaoke system provided with the unit 38 'will be described. The same components as those described above are denoted by the same reference numerals, and description thereof will be omitted.

As shown in FIG. 10, this centralized karaoke system is obtained by adding a detection unit 37 'and an input unit 38' to the configuration shown in FIG. Statistical processing unit 35
'A detection unit 37' (corresponding to the control unit constituting the centralized control device 3) which has received the number of disks for suppressing the occurrence of disk blocks for each disk below the specified value calculated by '
Compares the number of disks with the number of disks stored in the database unit 34'A, and detects a disk having two different values from the detection unit 37 '(corresponding to the control unit constituting the central control unit 3). ), And transfers the track numbers and the number of added / deleted discs to the display unit 36 '. In this case, as in the previous case, the system administrator finally adds or deletes the corresponding disk as necessary based on this information.
Then, when it is added or deleted, the input unit 38 '(corresponding to the panel keyboard unit constituting the centralized control device 3 described above)
Is operated to change the number of stored disks of each disk registered in the database unit 34'A.

Here, the centralized karaoke system described below is obtained by adding information on the storage location and the free storage space of each disk to the database section 34'A to the configuration shown in FIG. This database section 34'A
Is the second in the I / F section constituting the centralized control device 3 described above.
And the second memory unit is used to manage a large number of disks stored in the karaoke playback devices 21 to 23. In order to manage a large number of disks, data relating to disk tray number management (disk shelf number management) (request shelf number management) is used. table,
As described above, each data such as the song title table and the history data / system information is stored in the memory. The same components as those described above are denoted by the same reference numerals, and description thereof will be omitted.

As shown in FIG. 11, the difference from the configuration shown in FIG. 10 is that there are a plurality of music information storage sections 33 ', and the same kind of disc or new music is stored in the disc stored and held therein. When adding a disk, or deleting a disk that is duplicated and held here or a disk that has hardly any number of requests, which one of the plurality of music information storage units 33 'should be used? Is a point. As shown in the figure, the request processing unit 32 'indicates that the request from the terminal 1A' to 1N 'indicates which music information storage unit 33' is requesting the music of the disc stored and held in the music information storage unit 33 '. Each time the disk usage count information is requested, it is counted up and the result is recorded in the database unit 34'A. The request processing unit 32 'is a database unit 34'A
In the case of adding a disc, the music information storage unit 33 'storing a relatively large number of infrequently used discs (instead of infrequently used discs) is added to the music information storage unit 33'. This information is displayed on the display unit 36 'so as to add a new disk. Also, in the case of disc deletion, a display is made so as to start from the music information storage unit 33 'in which a large number of frequently used discs are stored. The subsequent procedure is as described above.

Therefore, the centralized karaoke system according to the present invention described here is the same as the centralized karaoke system 1 shown in FIG. 1 and FIG. Based on the number of times of performance and the number of occurrence probabilities that the karaoke software requested from a plurality of terminal devices is the same, addition / deletion of the karaoke software is detected so that the occurrence probability is equal to or less than a predetermined value. Karaoke system).

As a result, data such as the number of times the disk block was actually played and the number of disk blocks are statistically processed with respect to the risk ratio of the disk block set in consideration of both economic efficiency and serviceability. By calculating the expected value of the risk factor of the block and comparing the two values, karaoke is centrally managed with the minimum required number of disks in a semi-automatic manner (because it is the system operator who decides to add or delete disks). Can operate the system.

[0154] 4. Disk shelf number change control By the way, the centralized karaoke system 1 having the above-described configuration includes:
At initial system setting, up to 600 sheets per unit (standard 36
Depending on the number of karaoke playback devices 2 capable of storing 0 to a maximum of 600 discs, for example, the number of disc sets (the number of sets, the number of series, the number of genres of music) in which a number of discs of the same series are set as one set. The user manually determines the disc shelf number, and sequentially stores the discs therein (the above-described music number / shelf number conversion processing, music name registration processing, etc.). In this way, by storing a large number of disks constituting one set collectively, a continuous disk symbol (disk number) can be assigned a continuous rack symbol (shelf number). It is convenient.

By the way, if the combination of the number of karaoke playback devices 2 and the number of disk sets becomes complicated after the system initialization in which such disk shelf number management is performed (for example, the number of karaoke playback devices 2 is changed). When it is desired to frequently replace the number of disk sets composed of a large number of frequently requested disks to be stored therein, or to change the number of disk sets by changing the number of karaoke playback devices 2 Etc.), the disc shelf number management process at the time of initializing the system is broken, and as a result, a disc shelf number update process for re-storing a set of disks collectively in accordance with a new combination of the number of karaoke players 2 and the number of disk sets. It is required to inform the user that the operation is performed.

In order to automatically perform the disk shelf number updating process in performing such publicity, the number of karaoke reproducing apparatuses 2, the number of disk sets, the number of disks constituting one set (the number of disk sets), This can be performed by a method of setting the disk number based on each data such as the position of the disk.

First, a brief description will be given of a process from the request to the provision of music information. The same components as those described above are denoted by the same reference numerals, and description thereof will be omitted. As shown in FIG. 12, the user's request input at the terminals 1'A to 1'N is transmitted to the request processing unit 32 'via the transmission path 2' and the I / F unit 31 '. Here, the request processing unit 32 ′ requests the content of the request (request music).
Is transmitted, a music information output command corresponding to the requested music is transmitted to the music transmission unit 33 ″ (corresponding to the serial input / output unit of the I / F unit 31 ′ included in the centralized control device 3 described above). . This output command is sent to all changers 33 '.
A to 33'N (corresponding to each of the above-mentioned karaoke reproducing apparatuses 2), and the disc is reproduced by the disc player of the changer in which the disc of the music information corresponding to the request is stored.

The music information (karaoke software data signal) reproduced from the player of the changer is transmitted to the terminals 1'A through 1'A through the music transmission section 33 '', the I / F section 31 ', and the transmission path 2'. 1'N. The terminal that has made the request can reproduce the music information (video and audio) on the monitor 8 and the speaker 10.

The configuration shown in FIG. 13 is different from the configuration shown in FIG. 12 in that the database unit 34A 'and the statistical processing unit 35
, A display unit 36 ′, and an input unit 38 ′, and the added components embody the various functions of the central control device 3 described above. The same components as those described above are denoted by the same reference numerals, and description thereof will be omitted. The input section 38 'corresponds to a panel keyboard section of the centralized control device 3, and by operating a corresponding key of the panel keyboard section, input / changes shelf number data relating to the "disk shelf number management" described above. Etc. can be performed. The display unit 36 'can display data relating to the disk shelf number update processing described above.

Here, regarding the arrangement of disks in the karaoke reproducing apparatus 2 at the time of system initial setting, conventionally, in most cases, one changer is basically provided for one set of disks, and as shown in FIG. They were arranged in the order of the shelf numbers of each changer. .., 200, and 200 in the changer 33'A.
01 are arranged in the order of the shelf numbers. These disks 1-2
00 constitutes one set of disks. Similarly, the shelf number 1, the shelf number 2,..., The shelf number 200, and the shelf number 201 of the changer 33'B are Disk 1, Disk 2,.
., 200, and 200 in the changer 33'C.
01 are arranged in the order of the shelf numbers. Although not shown here, when the number of karaoke reproducing apparatuses 2 is different from the number of disk sets, the user manually determines the shelf number and arranges the disks.

On the other hand, in this embodiment, the number of disks input by the user by operating the input section 38 ',
Based on the information on the number of disk sets, the statistical processing unit 35 'performs an arithmetic process described later in accordance with data relating to disk shelf number management including the request shelf number table registered in the database unit 34'A, and automatically sets the disk shelf position. To decide. The determined shelf arrangement is memory-managed in the database unit 34'A. Further, by displaying the determined shelf position of the disc on the display unit 36 ', the user can instruct the karaoke reproducing apparatus 2 to instruct the disc according to the instruction.
(Changers 33'A to 33'N).

An example of the calculation is shown below, and examples of the arrangement of disks according to the calculation result are shown in FIGS. For example, the disc number (disc symbol) D to be put on the shelf T of the karaoke player A is: D = [(A-1) * (d1 * s) / a + (T + (c-1))] 3) However, d1: the number of discs in one set, s:
Number of disk sets, a: number of karaoke players (number of changers), c: disk tray setting start position (shelf number)

As a result, as shown in FIG. 15, a large number of disks constituting one set can be collectively rearranged in the order of the new shelf number of each karaoke player 2. That is,
Changer 33'A shelf number 1, shelf number 2, ..., shelf number 13
Disk 1, Disk 2,..., Disk 133, and Disk 134 are arranged collectively in the order of the shelf numbers. Changer 33'B shelf number 1, ..., shelf number 13
4, disks 135 to 200, disks 1, 1 to 65, and disk 65 are collectively rearranged. Also, the shelf numbers 1,..., 13 of the changer 33'C
3, the shelf number 134 has a disk 66, a disk 67,.
The disks 200 and 201 are rearranged collectively.

Further, as shown in FIG. 16, the disks can be rearranged collectively in the order of the new shelf number of each karaoke reproducing apparatus 2. .., 133 of the changer 33'A, the discs 1, the discs 2,..., And the discs 67 are arranged collectively in the order of the shelf numbers. Shelf number 1,..., Shelf number 134 of the changer 33'B
, Disk 200, disk 1, disk 65, and disk 65 are collectively rearranged. In addition, shelf numbers 1,.
4 includes disk 66, disk 67,.
0, disks 201 are collectively rearranged.

The flow of information for relocating such a large number of disks collectively according to the size of the system (the number of shelves) is as follows. As shown in FIG.
The user's request input at “N” is transmitted via the transmission path 2 ′, via the I / F unit 31 ′, and the request processing unit 32 ′
Sent to. The request receiving unit 32 compares the request content with data (request shelf number table, song name table) relating to disk shelf number management stored in the database unit 34'A, and compares the request content with any changer 33. It is determined whether the music is stored in the shelf number of 'A to 33'N, an output command is transmitted to the music sending unit 33'', and the requested music is reproduced from the corresponding changer 33'A to 33'N in accordance with the request. ,
The corresponding terminal 1'A in accordance with the instruction in the music sending section 33 ''
To 1'N via the I / F unit 31 '.

Therefore, in the centralized karaoke system according to the present invention described above, the above-mentioned centralized control device 3 is arranged such that the karaoke reproducing device 2 has a disk tray (recording medium storage shelf).
Section (database means) 34'A for recording storage shelf data relating to storage medium, input means for inputting recording medium data relating to recording media to be stored in the storage medium storage shelf, and based on the storage shelf data and recording medium data. A centralized karaoke system comprising an arithmetic means for calculating a storage medium storage shelf of a recording medium and an output means for outputting the calculation result.

[0167] 5. Lifetime uniformity control When a plurality of changers or players described above are used, usually, the frequency of use of each device is not recorded. For this reason, the use of control is biased by the control method, and the frequently used device is quickly consumed, the probability of failure is high, and the life of individual devices varies, and therefore,
There is a risk that the life of the entire system will be shortened.

In consideration of the use efficiency of the system resources, it is preferable to control the use frequency of each device so that the use frequency of all devices becomes uniform and the life of the entire system is maintained long. Hereinafter, the control method will be described. The same components as those described above are denoted by the same reference numerals, and description thereof will be omitted.

As shown in FIG. 17, terminals 1'A to 1'N
The user's request input in step 1 is transmitted via the transmission path 2 '
It is transmitted to the request processing unit 32 'via the / F unit 31'. In response to this, the request processing unit 32 'processes this request information, and uses the music information storage unit 33' with the disc to be used and the music information output units 33'a to 33'a to be used.
33'm is designated and a music information output command relating to the requested music is transmitted. The music information storage unit 33 'provides a flow of a series of information for providing music (karaoke software data signal) via the I / F 31' to the requesting terminal in accordance with the instruction, as described above.

Here, the request processing unit 32 ′ is arranged so that the database unit 3 corresponding to the number of the music information output units 33 ′ a to 33 ′ m used for the music information output for each music information output
It is assumed that the data of 4′A is counted up. First, the request processing unit 32 'is connected to the terminals 1'A to 1'
When a request for new music information is received from 'N,
It is checked whether the music information requested from the music information storage unit 33 'is usable or not and whether the music information output units 33'a to 33'm are free. If the music information output units 33'a-3
If there is only one free space in 3'm, the music information output unit is used to send the requested music information output command to the music information storage unit 33 ', and the database unit 34
The data corresponding to 'A is counted up.

However, the music information output units 33'a to 33 '
If there are a plurality of vacancies in m, the request processing unit 32 '
Detects a music information output unit that has the least number of uses and is capable of outputting music information from the past use counts of the music information output units 33′a to 33′m recorded in the database unit 34′A, Using the music information output unit, the request for outputting the requested music information is sent to the music information storage unit 33.
And counts up the corresponding data in the database unit 34'A.

In this way, by controlling the use frequency of all the apparatuses to be uniform, the consumption of each apparatus is not biased. As a result, the average life is greatly improved, and the efficiency of using system resources can be increased.

6. Request Optimal Reproduction Control In the case of a system having a greater number of music information output units (players) 33'a to 33'm than the terminals 1'A to 1'N, players who are not performing (empty) The time from the end of the performance of the current request music to the performance of the next request music is often used as a standby for playing the next request music as described above. The waiting timing is an operation in which, after a lapse of a set time from the start of the performance of the current requested music (for example, after the elapse of the resongable time described above), the empty player is set to a standby state for playing the next requested music. Control to enter. As another control method, there has been proposed an operation for entering the standby state when the remaining playing time of the previous requested music reaches a certain set time.

In these control methods, however, the performance time of the previously requested music piece is not a fixed length, so that the next requested music piece of the previously requested terminal is given priority (empty).
The player does not always perform the standby operation. In other words, despite the fact that the next request song of the terminal that has requested the song that is still playing is waiting with priority, even if the requested song has not been completed before the terminal, the requested song has already been played. There is a case where the next request music of another terminal for which the processing has been completed is not yet in the standby state, and the (vacant) player is not operated efficiently, which causes a problem that the efficiency of the entire system is reduced.

This problem can be solved by a control method of putting the next requested music in the terminal in which the performance of the requested music ends first in a standby state. However, in this control method, when the operating rate of the system is low (for example, when the number of requests is small for the number of terminals), the next music is not waited until the remaining playing time becomes less than a certain set time. If the user cancels the music piece before the time reaches the predetermined time, the access time of the music information storage unit (changer) 33 ′ (to stop the performance of the music piece) until the next music piece is played. The command is output from the request processing unit 32 'to the music information storage unit 33', whereby the music player waits until the performance of the player during the performance is stopped), thereby reducing the efficiency of the system.

Therefore, the efficiency of the entire system is improved by a timing control method for waiting for the next music as follows. The same components as those described above are denoted by the same reference numerals, and description thereof will be omitted. As shown in FIG.
The user's request input in 'A to 1'N is
The request information is transmitted to the request processing unit 32 'via the I / F unit 31 of the center A and the request information is processed by the request processing unit 32', and the disk used for the music information storage unit 33 'and the music information output used The music information storage unit 3 transmits the music information output command by designating the units 33'a to 33'm.
At 3 ', the flow of a series of information for providing music to the corresponding terminals 1'A to 1'N via the I / F unit 31' according to the instruction is as described above.

Further, the total number of terminals N <the number of music information output units m <
It is assumed that the number of terminals is N × 2 and the request of the terminal has received a plurality of music pieces, and the music information output unit that is not performing is used for standby of any terminal. It is assumed that the performance time of each music is recorded in advance in the music length management unit 39 '. First, the request processing unit 32 'is connected to the terminals 1'A to 1'.
Music information output unit 33
The data is transferred to each of the terminals 1'A to 1'N using 'a to 33'm. At the same time as outputting the music information, the request processing unit 32 'requests the remaining playing time calculating unit 40' to calculate the remaining playing time of the output music. The remaining playing time calculation unit 40 'that has been requested to calculate the remaining playing time calculates the remaining playing time of the output music information.

Next, the request processing section 32 'outputs music information output sections 33'a to 33' which are not outputting music information (empty).
When 'm is detected, the remaining playing time of all outputs is obtained from the remaining playing time calculating section 40', the shortest playing time terminal is detected from the remaining playing time terminals, and the next music piece for the terminal is detected. Wait at 33'a to 33'm. Then, after the output of the previous terminals 1'A to 1'N ends, the transfer is started from the music information output units 33'a to 33'm on standby. By performing these controls periodically, the terminal whose performance ends first can wait first. In addition, if there are the music information output units 33'a to 33'm for standby, the next music can be waited immediately after the performance, so that the probability that the next music is waiting is high even if the music is canceled after the performance is started. Become.

In the above example, it is necessary to previously record the performance time of each music in the music length management section 39 ', but in the case shown in FIG. 19, the music information output sections 33'a to 33'm use the music information output sections 33'a to 33'm. By providing the remaining playing time detecting unit 41 'for obtaining the remaining playing time from the managed remaining playing time (using a CD or the like), it is not necessary to register the playing time of each song in advance.

Therefore, the request processing section 32 'obtains the above-mentioned remaining performance time from the remaining performance time calculation section 40'. Here, the request processing section 32 '
The same effect as described above can be obtained except that it is obtained from the remaining playing time detecting section 41 '.

As described above, the next tune is waited in order from the terminal whose performance ends first, so that the system use efficiency is improved. Also, if there is room in the player, it will be used as described above, so even if you cancel while playing,
The probability of waiting for the next song is higher than in other systems.

And a signal path for independently connecting the karaoke apparatus to the karaoke apparatus. On the basis of the number of the karaoke players, the recording mediums mounted on the respective shelves of the respective karaoke apparatuses are equalized in number. Since the medium is arranged on the shelf, in consideration of both economical efficiency and serviceability, for example, at the time of initial setting, a large number of assembled discs are uniformly set in each karaoke reproducing apparatus from the number of system components and disc setting contents. Since it is possible to obtain the shelf position information that enables the disk set to be equally stored so that the disk sets can be divided and stored so that the number of disks can be stored, there is an effect that the disks of the set can be efficiently managed. .

A centralized karaoke system according to a fourth aspect of the present invention is provided with a karaoke reproducing apparatus which is equipped with a recording medium on which a plurality of karaoke software is recorded and which outputs requested karaoke software.

Karaoke software installed on the terminal device In such a case, among the karaoke players equipped with the requested karaoke software, the karaoke player having the least number of uses is preferentially used, so that all the karaoke players are used. Since the frequency of use becomes uniform and the wear of each device is not biased, the average life of all karaoke playback devices is greatly improved, and the usage efficiency (service life) of the entire system can be greatly improved. There are effects such as being able to do.

A centralized karaoke system according to a fifth aspect of the present invention is provided with a karaoke reproducing apparatus for mounting a recording medium on which a plurality of karaoke software is recorded and outputting the requested karaoke software, And a plurality of terminal devices for playing back the karaoke software related to the supplied request, a centralized control device for centrally controlling the karaoke playback device and the terminal device, the centralized control device, and the terminal device. And a signal path for independently connecting the karaoke software, wherein the centralized control device detects the remaining playing time of the karaoke software being played on each terminal device, and detects the remaining playing time. Waiting to give priority to the next request from the terminal device that is playing karaoke software with a short time Since the Laoke playback device is controlled, for example, it is possible to wait for the next requested song to be played in order from the terminal device that finishes playing first, so that it is possible to improve the use efficiency of the system, If a karaoke player does not have a running disc player, it will use this.Therefore, even if the requested song is canceled during the performance, the probability that the next song will be waiting is higher than in other systems. That is, there is an effect that the time from the request to the reproduction of the requested music can be extremely short.
