Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a broadcasting center with a request response function capable of broadcasting music information for broadcasting in response to a music broadcasting request individually made by a viewer via a communication means.

[0002]

2. Description of the Related Art At present, a new form of TV broadcasting called interactive television is becoming popular between a local television broadcasting center such as a CATV system and a subscriber terminal. .
Then, the broadcasting center of such a system not only sends the decided information at the decided time, but also sequentially broadcasts the broadcasting information according to the broadcast request individually made by the viewer in a predetermined order. It also has a request response function. For example, a program time frame (or a dedicated channel provided) that handles only karaoke broadcasting called a karaoke program is adopted, and in this program, a request from a viewer is received via a telephone, and the request is received. That is to broadcast karaoke according to.

However, in the conventional karaoke request program, since the song requested by the user is simply played as it is, it is not a key (key) that the user can easily sing, or it is a uniform full chorus. It was
In other words, in a so-called stand-alone type karaoke device, the user can change the performance key to a height at which he or she can easily sing, or specify two chorus patterns to cut the third and subsequent performances to the second performance. Although it was possible to change the performance mode according to the wishes, such a performance mode was not realized in this karaoke request program.

As described above, there are cases in which the music does not meet the taste of the user, and even if the song is requested by the user, the user may be unsatisfactory or uncomfortable, and the feeling of making a request is reduced. I will let you. Also, for example, the playing key is too high, so that the user cannot sing along with the song after all, which leads to dissatisfaction because the user can only listen. in this way,
There was a problem that it could not fully function as a karaoke request channel.

The present invention improves the convenience of the user and enables the use of the broadcasting system by enabling the user to request a change in the performance mode such as changing the performance key or changing to a performance with two chorus cuts. The purpose is to promote.

[0006]

In order to achieve this object, the invention according to claim 1 receives a music broadcast request individually made from a viewer through a communication means and makes a request. Broadcast request receiving means for automatically storing as data in the storage means and broadcasting means for sequentially broadcasting the music information for broadcasting stored in the request storage means according to the music broadcast request in a predetermined order. In a provided broadcast center with a request response function, the broadcast request reception means, when receiving the music broadcast request, also receives performance mode information of the music selected from a plurality of candidates in addition to music identification information, It is possible to store them in association with each other, and the broadcasting means broadcasts the broadcast music information in a performance mode based on the performance mode information stored correspondingly. It is a broadcasting center which is characterized.

The broadcasting center of the present invention having the above structure is
The broadcast request receiving means receives the music broadcast request individually made by the viewer via the communication means, and automatically stores the music broadcast request in the request storage means as data. Then, the broadcasting unit sequentially broadcasts the broadcasting music information corresponding to the music broadcasting request stored in the request storage unit in a predetermined order.

In addition to having such a basic function, the broadcast request receiving means, when receiving a music broadcast request, also receives performance mode information of the music selected from a plurality of candidates in addition to music identification information, They can be stored in association with each other. Then, the broadcasting means sends the broadcasting music information to
Broadcast in a performance mode based on the performance mode information stored correspondingly.

It is considered that the performance mode information includes the following information, for example. Claim 2
In the example shown in (1), the performance key information of the music is included. Claim 3
The information shown in (1) includes information for designating one of a succeeding cut pattern for cutting the subsequent part of the music and a two-chorus pattern for cutting the third and subsequent parts of the music to the second and third performances. According to the present invention, in the case where the music broadcast request is for a karaoke music, one of an amateur mode with a melody line added and a professional mode with no melody line or a small volume is added. Contains specified information.

As described above, since the user can request a change in the performance mode, for example, in the case of karaoke, the standard performance key is too expensive to sing along with the music. However, you can change to the performance key you want. Further, if the succeeding performance cut pattern or the two-chorus pattern is designated, a part of the music is omitted, which is effective when it is desired to enjoy as many karaokes as possible within a certain period. It is preferable to sing a certain song in full chorus, but for a certain song, up to number 2 is sufficient, and it is preferable because individual songs can be designated. In addition, for songs that I remember well, I put them in professional mode without adding melody lines or adding them at a low volume, and for songs I didn't remember much and were not confident about, I added amateur mode to add melody lines. Can be one.

As described above, the change of the performance mode such as the change of the performance key or the change to the performance with two chorus cuts can be designated for each song, so that the convenience of the user is improved and, as a result, the broadcast is performed. It also leads to the promotion of system usage.
Further, as described in claim 5, when the performance mode information is not stored, the broadcasting means broadcasts the broadcast music information in a standard performance mode predetermined for each broadcast music information. It is good to do so. In other words, you only have to make a request if you want to perform in a mode other than the standard performance mode.
In other cases, the standard performance mode is automatically performed. For example, even when the standard performance is performed, it is troublesome to specify the standard performance mode each time, such as designating the standard performance key and the full chorus. Therefore, it is convenient if the performance is automatically performed in the standard performance mode when not specified.

According to claim 6, the viewer can use the telephone to send the request. That is, the telephone line is used as the communication means, and the broadcast request receiving means is configured to be able to receive the music broadcast request from the viewer by the dial pulse signal or the DTMF signal which can be transmitted from the telephone. Note that there are currently two types of signals transmitted from telephones, and dial pulse signals are signals transmitted by dial type telephones.
The (dual tone multi-frequency) signal is a signal transmitted by a push button type telephone. Either type of telephone can be used.

In this case, for example, a voice response function of automatically receiving a telephone call from a viewer and providing guidance by electronic voice, and a code receiving function of receiving a code transmission using a dial tone by the telephone are provided. A predetermined guidance voice is played by the response function, and accordingly, in addition to the karaoke song number and the viewer identification number requested by the viewer, the above-described performance modes and the like are input with push buttons or the like, and the dial tone is input. It is convenient to receive it as the code used.

For example, in the case of a performance key, the standard key of the music is set to 5, and the tone is lowered by 4 semitones as it goes down 4 → 3 → 2 → 1 and is raised by 6 semitones as it goes up 6 → 7 → 8 → 9. It is conceivable that the above setting is made, and that is responded as a guidance voice to prompt the input. Also, in the case of the two alternatives such as the above-mentioned two chorus and after cut, or the professional mode and the amateur mode, a guidance voice in which one is designated by "1" and the other is designated by "2" Is enough. Of course, also for these, the third and subsequent selection candidates may be set.

In the above claim 6, the broadcast request receiving means receives the music broadcast request individually made by the viewer via the telephone line. However, the music broadcast from the viewer is broadcasted. The method of receiving the request may of course be any other method. For example, if bidirectional full-duplex communication is realized via the CATV coaxial cable, the request may be received via the coaxial cable.

The broadcast music information broadcast from such a broadcast center may be, for example, information related to karaoke music or normal music with vocals. However, in the case of a song with vocals, since the vocal is important, the settings such as professional mode and amateur mode in the case of karaoke are not made. As for karaoke, it is becoming common knowledge that the image in which the lyrics telop is combined with the background image is displayed along with the karaoke performance. It is possible to let it broadcast. In this case, a so-called CATV system can be used as it is. In the case of the CATV system, the broadcasting center and the subscriber terminal are connected by wire, but they may be wireless as in a normal broadcasting system.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the broadcasting center of the present invention will be described below with reference to the drawings. FIG.
FIG. 3 is a block diagram showing a schematic configuration of the broadcasting center 10 of the present embodiment. As shown in FIG. 1, the broadcasting center 10 includes a host computer 11 as a control means, an external storage device 12 as a storage means, a display device 13, a karaoke reproducing device 14, and a broadcasting means as a "broadcasting means". 16
And a voice response device 20 as "broadcast request receiving means". In addition, the broadcasting center 10 uses a large number of subscriber telephones 50 via a public telephone line 40 as a communication medium.
Connected to the public telephone line 40 and subscriber telephone 50
And form a communication means.

Each of the constituent devices will be described, including the role of the broadcasting center 10 and the relationship with the broadcasting system. The voice response device 20 is for receiving a music broadcast request from a viewer via the public telephone line 40 and the subscriber telephone set 50. The broadcasting center 10 stores a music broadcasting request individually made by a viewer,
It has a request response function that sequentially broadcasts broadcast music information (karaoke information in this embodiment) according to the music broadcast request. Main broadcasting center 10 by TV
While listening to a television receiver (not shown) connected to, a request is made to broadcast desired karaoke piece information through the public telephone line 40 by the subscriber telephone 50 in hand.

This music broadcasting request is made by a predetermined "request code". This is a "song number" for general karaoke equipment only for providing karaoke viewing.
Is synonymous with. Since the request is made by a numerical code, the viewer actually makes a tone transmission of the request code by dialing the subscriber telephone set 50 or pressing down the touch-tone telephone. It is assumed that this request code has been notified to the viewer in advance by a distributed product or the like.

Further, in this embodiment, not only the karaoke piece can be specified as the music broadcast request, but also the performance mode can be specified. The play mode that can be specified is either the change of the performance key of the music, the after cut pattern that cuts the after performance of the music, or the two chorus patterns that cut the third and subsequent songs of the music to the second performance, and the melody. It is either an amateur mode with a line added, or a professional mode with no melody line or a small volume. As in the case of the request code, these designations are also made by dialing the subscriber telephone set 50 or by tone transmission of a numeric code by pressing down the touch-tone telephone.

For example, in the case of a performance key, the standard key of the music is set to 5, and the tone decreases by 4 semitones as it goes down 4 → 3 → 2 → 1 and becomes semitones higher as it goes up 6 → 7 → 8 → 9. Is set. Also, in the case of two alternatives such as 2 chorus and after cut, or professional mode and amateur mode, let either be designated by "1",
The other is set to be designated by "2".

The call from the viewer is automatically accepted by the voice response device 20 in the broadcasting center 10. The voice response device 20 has a built-in synthetic voice means (not shown).
Sends a message registered in advance by the user, and requests the viewer a code for specifying the performance mode (hereinafter,
It is referred to as a performance mode code. ), And is controlled by the host computer 11 to perform the above-described call reception, message transmission, and pulse code reception.

The request code or performance mode code received by the voice response device 20 is checked by the host computer 11 whether the code is valid or not.
Judged by collating with the database on the external storage device 12, and if valid, the CPU in the host computer 11
It is stored in the memory 11b (see FIG. 2). Note that this C
The PU memory 11b corresponds to "request storage means".

When the host computer 11 accepts the request, the host computer 11 creates a message for notifying the request as voice information. Then, the voice response device 2
From 0, it responds to the subscriber's telephone set 50 on the viewer side that has made a broadcast request via the public telephone line 40.

Further, the stored request code and performance mode code are passed to the karaoke reproducing apparatus 14 controlled by the host computer 11 to reproduce audio / video. In addition, the karaoke reproducing apparatus 14 of the present embodiment.
Is capable of reproducing a karaoke performance sound and a background image in which lyrics telops are combined. Therefore, the broadcasting means 16 of this embodiment is a television broadcasting means. It should be noted that, in view of the gist of the invention, no video is required, so the karaoke reproducing apparatus 14 reproduces only the karaoke performance sound, and the broadcasting means 16 may be so-called radio broadcasting means.

The broadcast contents broadcast by the broadcasting means 16 are received by a receiving facility such as a television receiver on the viewer side and can be viewed as a karaoke program. In addition,
The broadcasting center 10 and the receiving equipment on the viewer side may be connected by wire like a CATV system, or may be wireless like a normal broadcasting system.

The display device 13 is connected to the host computer 11 and can display these conditions. This is used for confirmation by the operator of the broadcast center 10. Subsequently, a signal flow centering on the host computer 11 will be described with reference to FIG.

As shown in FIG. 2, the voice response device 20 is connected to the CPU 11a of the host computer 11 by a control signal. The CPU 11a controls the voice response device 20 with respect to waiting for an incoming call on the public telephone line 40 (see FIG. 1) and control with respect to the transmission of a voice message in the device 20 after receiving a call (selection from a plurality of messages). . The voice response device 20 returns the dial pulse received through the public telephone line 40 to the host computer 11 as numerical information. As a result, the viewer's request is automatically accepted by the public telephone line 40. The numerical value returned from the voice response device 20 is stored in the CPU memory 11b.

The external storage device 12 is a host computer 1 in which a database concerning request codes is stored.
1 is external storage, and data is read and written between the devices. As a result, the CPU 11a performs request code search / verification and log recording.

The karaoke reproduction device 14 is connected to the CPU 11a by a control signal. The CPU 11a transmits a request code (song number) and a performance mode code to cause the device 14 to reproduce the karaoke music, and also to reproduce the karaoke music. Control such as start and end can be performed. In addition, the karaoke reproducing device 14 returns the reproduction status (reproducing, reproduction end, etc.) to the CPU 11a. Thereby, the CPU 1
1a can play a karaoke piece by request code.

Next, the operation of the broadcasting center 10 of this embodiment will be described with reference to the drawings. 8 to 14 are CPUs
11 is a flowchart showing a processing procedure of a program executed by 11a, and FIGS. 3 to 7 are data structure diagrams handled by this program. The details of the processing flow will be described below. 8 to 13 are flowcharts of request automatic acceptance / registration processing, and FIG. 14 is a flowchart of request reproduction processing. These processings are so-called multitask processings that operate independently at the same time.

First, the automatic request acceptance / registration process (FIGS. 8 to 13) will be described. This processing is to automatically accept a request from the subscriber side through the public telephone line 40,
A procedure for registering the request in the CPU memory 11b will be described. The subscriber does not simply mean that he / she can receive the broadcast from the broadcasting center 10, but that he / she has the right to make a request. For example, CA
In a TV system, all are subscribers if they are also automatically entitled to the request when they subscribe to the system. In the case of broadcasting in a normal wireless format, for example, it is conceivable to separately contract to collect a predetermined fee instead of making a request. In that case, only the person who made the contract becomes the subscriber.

First, in the first step S100 of FIG. 8, the voice response device 20 is controlled so that the incoming call can be made via the public telephone line 40, and in the subsequent step S110, there is an incoming call from the subscriber telephone set 50. Wait until. Then, if there is an incoming call (S110: YES), the process proceeds to S120.

In S120, the voice response device 20 sends a voice response message (for example, "please enter the subscriber number") to prompt the user to enter the subscriber number to be visited first. Then, in S130, the transmission of a dial pulse from the subscriber telephone 50 is awaited. The entered number is S
At 140, the data is stored in the subscriber code area C3 of the request reception buffer (see FIG. 5) on the CPU memory 11b. This is repeated until all the 5-digit subscriber numbers are input (S150).

When a 5-digit subscriber number is entered (S15
(0: YES), the process proceeds to S160, and it is verified whether or not the subscriber number is valid. This is done by referring to the subscriber database (FIG. 7) on the external storage device 12. As a result of this comparison, if it is determined that the number is not valid (S170: NO), a voice message (for example, "Please re-enter subscriber number") requesting re-input is reproduced (S180), and the process proceeds to S130. Return.

If the first entered subscriber number is valid, or if the second entered subscriber number is valid (S170: YES), the process proceeds to S190 (see FIG. 9). In S190, a voice response message is sent to prompt the user to enter the request code. In subsequent steps S200 to 220, waiting for dial pulse transmission, the input number is stored in the request code area C2 of the request reception buffer (FIG. 5) until the 5-digit request code is input. repeat.

When a 5-digit request code is input (S220: YES), the request code is collated. This is executed by querying the request database (FIG. 3) on the external storage device 12. And S14
A value of 0 determines whether the number is valid. If it is determined that the number is not a valid number (S240: NO), the process proceeds to S250, a voice message (for example, “Please re-enter request code”) requesting re-input is played, and the process returns to S200.

If the request code input first is valid, or if the request code input again is valid (S240: YES), the process of S260 of FIG. 10 is performed to specify the next performance mode code. Move to. In S260, a voice response message is sent out to prompt input of a performance key selection code which is one of the performance mode codes. Specifically, the performance key is set so that the standard key of the tune is 5, and it decreases by 4 semitones as it goes down 4 → 3 → 2 → 1 and goes up by 6 semitones as it goes up 6 → 7 → 8 → 9. Therefore, a message to that effect is sent as a message to prompt selection input. In addition, in the present embodiment, if it is desired to perform in the performance mode originally set for the karaoke piece, it is troublesome to input the value of the performance mode. By inputting, it is set so that the performance mode can be set to the standard value. Specifically, three types of performance modes (performance key, melody line mode, and chorus mode) can be changed and set, so that the mode after "#" is input is automatically set to the standard value. It will be. Therefore, the fact is notified by the message in S260.

At the subsequent step S270, the transmission of the dial pulse is waited, and the inputted number is stored in the area C3 of the performance mode code of the request reception buffer (FIG. 5). The performance mode code area C3 can store three values, the first of which is the value of the performance key. Then, when the input is completed (S280: YES), it is determined in S290 whether or not it is a valid number. If it is determined that the number is not a valid number (that is, "1 to 9" or "#") (S2
(90: NO), shifts to S300, reproduces voice message requesting redo of input (for example, "Please re-enter code"), and returns to S270.

If the performance key selection code input first is valid or the code input again is valid (S290: YES), the process proceeds to S310. S
At 310, first, it is determined whether the input number is "#". If not "#", S32
Move to 0, set the performance key to the entered value,
Next, in step S34, the melody line mode is selected.
0 (see FIG. 11).

On the other hand, if the input is "#" (S
(310: YES), the process proceeds to S330, and the performance key, melody line mode, and chorus line mode are set to standard values. Specifically, since "#" indicating the standard value is already stored as the performance key in the area C3 of the performance mode code of the request reception buffer (FIG. 5), the melody line mode and the chorus line mode are automatically set. "#" Indicating a standard value is stored. Then, since the three performance modes have been determined in this way, after the processing of S330, the routine proceeds to S500 of FIG. The contents of this process will be described later, and the process from S340 (see FIG. 11) for the melody line mode selection process will be described next.

In S340, a voice response message is sent out to prompt the user to input the melody line mode selection code. Specifically, the amateur mode with the melody line added is selected as "1", and the professional mode with no melody line added or with a low volume is selected as "2".
Therefore, a message to that effect is sent as a message to prompt selection input. Further, if the above-mentioned “#” is input, in this case, the melody line mode and the chorus mode are automatically set to the standard values. Therefore, the fact is notified by the message in S340. The standard melody line mode in this case is either the amateur mode or the professional mode. This may be set as a standard value in consideration of the user group when constructing the system.

In subsequent S350, the transmission of the dial pulse is waited, and the input number is stored following the above-mentioned performance key number in the performance mode code area C3 of the request reception buffer (FIG. 5). When the input is completed (S3
60: YES), and in S370, it is determined whether or not it is a valid number. A valid number (that is, "1",
If it is judged not to be “2” or “#” (S37)
(0: NO), the process proceeds to S380 to reproduce a voice message (for example, “Please re-enter code”) requesting re-input, and returns to S350.

If the first inputted melody line mode selection code is valid, or if the re-entered code is valid (S370: YES), the process proceeds to S390. In S390, first, it is determined whether or not the input number is "#". If it is not "#", the process proceeds to S400, the melody line mode is determined to the input value, and then the process proceeds to S420 (see FIG. 12) for the chorus mode selection process.

On the other hand, if the input is "#" (S
(390: YES), the process proceeds to S410, and the melody line mode / chorus line mode is set to the standard value. Specifically, in the performance mode code area C3 of the request reception buffer (FIG. 5), a predetermined value is already stored as a performance key, and "#" indicating a standard value is stored for the melody line mode. Therefore, "#" that automatically shows the standard value for the remaining chorus line modes
Is stored. Then, since the three performance modes are determined in this way, after the processing of S410, the processing of S500 of FIG.
Move to.

Next, description will be made from S420 of FIG. 12 for the chorus mode selection processing. In S420, a voice response message is sent out to prompt input of a chorus mode selection code. Specifically, the succeeding cut pattern for cutting the succeeding part of the music is selected as "1", and the two chorus patterns for cutting the third and subsequent parts of the music up to the second performance are selected as "2". Therefore, a message to that effect is sent as a message to prompt selection input. Further, if the above "#" is input, the chorus mode is automatically set to the standard value. Therefore, the fact is notified by the message in S340. The standard chorus mode is full chorus.

In the subsequent S430, the transmission of the dial pulse is awaited, and the input number is input to the performance key code area C3 of the request acceptance buffer (FIG. 5).
Stored after the melody line mode number. Then, when the input is completed (S440: YES), it is determined in S450 whether or not it is a valid number. If it is determined that the number is not a valid number (that is, “1”, “2”, or “#”) (S450: NO), the process proceeds to S460, and a voice message (for example, “re-enter code”) is requested to redo the input. Please ") and play S430
Return to

If the chorus mode selection code that was input first is valid or if the code that was input again is valid (S450: YES), the process proceeds to S470. In S470, first, the input number is "#".
Is determined. If not "#",
The flow shifts to S480, the melody line mode is determined to the input value, and the flow shifts to S500.

On the other hand, if the input is "#" (S
470: YES), and proceeds to S490 to set chorus line mode to standard value. Specifically, since the value designated as the performance key and the value designated as the melody line mode are already stored in the performance mode code area C3 of the request reception buffer (FIG. 5), the remaining chorus lines are stored. For the mode, “#” indicating the standard value is stored and the process proceeds to S500.

In S500, a voice response message for notifying the viewer side that the acceptance of the request has been completed is transmitted, and in the subsequent S510, the line is disconnected. Note that S50
The voice response message of 0 may include, for confirmation, the specified performance mode in addition to the fact that the acceptance of the request is completed. For example, "The song No. XX has been accepted. In addition, the performance mode is one and a half lower performance key, professional mode, 2
Chorus mode. If you send a message such as "", "The song No. XX has been accepted. The performance mode is standard.", Make sure that the requesting person is in the performance mode he or she desires. It is convenient for

When the line disconnection process in S510 is completed,
The process moves to S520 (see FIG. 13). In S520, the received date and time is written in the area C1 of the reception time of the request reception buffer (FIG. 5) as a time stamp. When the processing up to this point is completed, the request reception buffer shown in FIG. 5 has three elements of the reception time C1, the valid request code C2, the performance mode code C3, and the valid subscriber code C4. Since it becomes possible to accept, the content of this request acceptance buffer (FIG. 5) is newly registered in the request code area B2 indicated by the acceptance pointer B5 in the request execution table (FIG. 4) in subsequent S530.

As shown in FIG. 4, the request execution table is made up of three items including a reproduction flag B1, a request code B2, and a performance mode code B3. And when making a new registration, the request reception buffer (Fig. 5)
The request code C2 and the performance mode code C3 are copied to the request code area B2 and the performance mode code area B3 indicated by the reception pointer, and the reproduction flag B1 is set to "not yet". In the initial state, the reproduction flag B1 is set to "none", and the request code B2 is set to an undefined value.

Upon completion of new registration in S530, S5
Move to 40. In S540, the reception pointer B5 is advanced to the next area on the request execution table (FIG. 4).
This operation is reflected in the operation of the request reproduction process (FIG. 14) described later. Further, in subsequent S550, in order to hold the received request as a log record, the reception time area D1, the request code area D2, and the subscriber code area D3 (FIG. 5) of the request log record (FIG. 6) on the external storage device 12 are stored. There is no area corresponding to the performance mode code area C3 in the request reception buffer of 1.).

After the processing of S550 is completed, the processing returns to the incoming call waiting state (S100 of FIG. 8) and the subsequent processing is repeated. Next, the request reproduction process (FIG. 14) will be described. This process shows a procedure of reproducing the request code and the performance mode code registered in the request execution table (FIG. 4) on the CPU memory 11b.

First, in the first step S610,
Playback pointer B4 in the request execution table (FIG. 4)
The reproduction flag B1 is extracted from the area indicated by. If the reproduction flag B1 is not “not yet” (S620: NO), all the reproduction of the registration contents of the request execution table (FIG. 4) has been completed or the registration contents are empty. The system waits for additional registration of the request (FIGS. 8 to 13) (S630).

On the other hand, if the reproduction flag B1 is "not yet",
The process moves to S640, and the request code B2 and the performance mode code B3 are taken out. The performance mode code B3 is specifically each value of the performance key, melody line mode, and chorus mode. Then, in S650, the request code B2 and the performance mode code B3 are passed to the karaoke reproducing apparatus 14, and a reproduction instruction is issued. Further, in S660, the reproduction flag B1 is changed to "medium", and in the following S670, the reproduction state of the karaoke reproducing apparatus 14 is checked.

This is repeated until the end of reproduction is instructed by the karaoke reproducing device 14 (S680: NO). Then, when the reproduction is completed (S680: YES), S690.
In step S700, the reproduction pointer B4 is moved to the next table.

After that, the process returns to S610 again to repeat the reproduction of the next request. Here, the above S650
Request code B2 and performance mode code B3
The operation of the karaoke reproducing apparatus 14 to which the above is given will be supplementarily described. For example, as shown in the request execution table of FIG. 4, in the case of the karaoke piece whose request code is "01826", the performance mode code is "##", so the performance key, melody line mode, Chorus modes are all standard values. Therefore, it is only necessary to execute a preset normal performance.

On the other hand, in the case of the karaoke piece whose request code is shown as "01301" in the same FIG. 4, since the performance mode code is "312", the performance key is "3", that is, one note down. It is a performance key, and the melody line mode is "1", that is, the amateur mode,
The chorus mode is “2”, that is, two chorus patterns. Therefore, the performance is started in the state of one note down from the preset performance key, and the melody line is added after the prelude is finished. further,
When No. 2 is finished, move to a predetermined performance end pattern,
The third and subsequent cuts are cut and the performance ends.

According to the broadcasting center 10 of the present embodiment described above, the karaoke request individually made by the viewer is received and automatically stored, and the karaoke performance information corresponding to the request is sequentially processed in a predetermined order. Broadcast. In addition to having such a basic function, when the karaoke request is received, the performance mode information is also received, and the karaoke performance can be performed in the performance mode based on the performance mode information. In the case of the present embodiment, three types of performance key, melody line mode and chorus mode can be designated respectively.

As described above, since the user can request the change of the performance mode, when using karaoke, the standard performance keys are too expensive to sing along with the music. However, you can change to the performance key you want. Further, if the succeeding performance cut pattern or the two-chorus pattern is designated, a part of the music is omitted, which is effective when it is desired to enjoy as many karaokes as possible within a certain period. It is preferable to sing a certain song in full chorus, but for a certain song, up to number 2 is sufficient, and it is preferable because individual songs can be designated. In addition, for songs that I remember well, I put them in professional mode without adding melody lines or adding them at a low volume, and for songs I didn't remember much and were not confident about, I added amateur mode to add melody lines. Can be one.

As described above, since the change of the performance mode can be designated for each music, the convenience of the user is improved, and as a result, the utilization of the broadcasting system is promoted. Further, in the case of the present embodiment, the standard value can be automatically designated by inputting "#" in the case of designating the performance mode. In other words, the request is made only when the player wants to perform in a mode other than the standard performance mode, and in other cases, the performance is automatically performed in the standard performance mode. For example, it is troublesome to specify each of the three types of performance modes, such as specifying the standard performance key, the melody line mode, and the full chorus in accordance with the guidance even when the standard performance is performed. Therefore, it is convenient if the performance is automatically performed in the standard performance mode when not specified. In the case of the present embodiment, if "#" is input at the time of designating the first performance key, all three types of performance modes can be designated as standard values with only one operation.

Further, such a performance mode can be designated from the subscriber telephone set 50, and in the broadcasting center 10,
This is convenient because it is not necessary to prepare an operator or the like for accepting it, and it is possible to automatically accept it through the voice response device 20. The embodiments of the present invention have been described above according to the specific examples. However, it goes without saying that the present invention is not limited to such specific examples and various implementations can be made without departing from the gist of the invention.

For example, in the above-described embodiment, three types of performance key, melody line mode, and chorus mode are illustrated as the performance modes that can be specified, but the performance modes are not limited to these. Further, although the numbers for designating each performance mode are input according to the voice response message for guidance, the numbers may be input in a predetermined procedure. For example, if you have a push-button phone,
Alternatively, after inputting a code for designating a tune number, a performance key, a melody line mode, and a chorus mode, "#" may be input to confirm each code. In that case, the role of “#” in the above-described embodiment, which is set to the standard value, may be substituted by “0”. In the case of a dial type telephone, since there is no "#", the end of inputting each code may be judged by time. Further, if there is no input for a predetermined time, the system may be set such that the standard performance mode is automatically set.

Further, in the above embodiment, an example in which it is used for broadcasting a karaoke program has been described. However, in the present invention, the number of servers supplying the music information for broadcasting is small, and the number of clients requesting music information for broadcasting is large. However, the main purpose of the application is to adopt an information supply mode called broadcasting because both parties are remote. Therefore, for example, other than karaoke, it may be a normal song with vocals.
However, in the case of a song with vocals, since the vocal is important, the settings such as professional mode and amateur mode in the case of karaoke will not be made.
