Field of the Invention The present invention distributes new musical sound data for karaoke performance, etc. through a telephone line, etc., and stores the distributed musical sound data in a storage unit of a terminal so that the musical sound data is selected each time. The present invention relates to a communication karaoke system that is used after being converted into voice.

[0002]

2. Description of the Related Art Conventionally, a karaoke machine for business use is a stand-alone type using a laser disk (LD) or a compact disk (CD), and when a new number of music reaches a certain number, a new LD or CD is pressed and added. It was Therefore, there was a problem that it took time to distribute the new music. Also, with the spread of karaoke, the amount of karaoke software has increased enormously, and there has been a new problem that requires a large space for storing it.

Against this background, recently, a new musical score is transmitted as digital musical tone data via a telephone line, this data is stored / accumulated in a storage unit in the terminal, and a specific song is selected from the accumulated musical pieces in this storage unit. A communication karaoke system for performing karaoke performance has been proposed and put into practical use. According to this communication karaoke system, there is no need to worry about the storage space of karaoke software as in the past, and new music is supplied at an early stage, so that interest is growing.

[0004]

However, in such a communication karaoke system, the terminal must be constantly connected to the host computer through a telephone line or the like. This is because it is necessary to promptly download the new musical tone data transmitted from the host computer to the terminal, and to transmit information regarding the music selection / performance status on the terminal side to the host computer at any time. In other words, the time when new music data is input to the host computer and the time when the karaoke terminal is used are not constant, and in order to prevent leakage of new music and leakage of feedback on the usage status, always connect to a telephone line or the like. You have to do it. The usage status on the terminal side is transmitted to the host computer for payment of copyright fees and for business reasons.

As described above, in the conventional communication karaoke system, the karaoke terminal cannot be taken out or lent because the karaoke terminal must be constantly connected to the telephone line or the like. Recently, local governments purchase karaoke sets and rent them at festivals and entertainments in the town, but there is a problem that the communication karaoke system cannot be used for such purposes.

Therefore, the present invention is a communication type karaoke system, which enables karaoke performance even if it is not connected to a telephone line, and does not cause delivery of new music data or feedback of usage status data. The purpose is to provide.

[0007]

DISCLOSURE OF THE INVENTION The present invention, which has been made to achieve the above object, provides a musical tone data storing means for storing musical tone data for karaoke performance and a musical tone data storing means for storing the musical tone data.

It is possible to accumulate song selections and performances at any time.

By connecting the performance terminal and the communication terminal, the new music data stored in the temporary storage section of the communication terminal is sent to the musical sound data storage means of the performance terminal through the interface section, and the performance terminal is connected. Stored in
Accumulated. On the other hand, the usage status data accumulated in the performance terminal is also sent to the temporary storage section of the communication terminal through the interface section. The data exchange between the terminals is controlled by the inter-terminal communication control means.

The usage status data thus stored in the temporary storage section is transmitted from the communication terminal to the host computer when the usage status is requested to be sent from the host computer or when the host computer is ready to receive the usage status. To be done. Also, the performance terminal storing the new music data can be separated from the communication terminal again and taken to an arbitrary place to enjoy the karaoke performance of the new music.

In this communication karaoke system, it is further preferable that the inter-terminal communication control means includes a connection timing instructing means for connecting the communication terminal and the performance terminal and instructing when to exchange data with each other. Is. With such a configuration, before a new period of data is temporarily stored in the temporary storage unit of the communication terminal, a considerable period of time elapses, or the usage status data of the performance terminal is full of usage status data. It is possible to instruct that the communication terminal and the performance terminal should be connected to each other, and it is possible to prevent the delivery of new music, the feedback of the usage status, etc.

[0012] Specifically, the connection timing instructing means may be configured to give the instruction based on the elapsed time after the new music data is stored in the temporary storage unit in the communication terminal, or in the performance terminal. The instruction can be made based on the accumulated amount of usage data.
In the former case, it is possible to ensure the early delivery of new music data, and in the latter case, it is possible to avoid the omission of accumulation and feedback of the usage status.

Further, in the communication karaoke system having these connection timing instruction means, it is desirable that the inter-terminal communication control means is provided on the performance terminal side. This is because the person who brought out the performance terminal can know that it is time to connect.

In these communication karaoke systems, the karaoke terminal is composed of one communication terminal and a plurality of performance terminals, and the temporary storage section of the communication terminal distinguishes the performance terminals from each other. It is also possible to store the data and store the new music data until the transmission of the new music data to all performance terminals is completed.

According to this communication karaoke system, although there are a plurality of performance terminals, since the communication terminals temporarily store the usage status data by distinguishing between the performance terminals, the person who pays the copyright fee is specified. be able to. Further, since the communication terminal stores the new musical score data until the transmission of the new musical score data to all the musical performance terminals is completed, the omission of delivery of the new musical score data to each musical performance terminal does not occur.

[0016]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an overall schematic configuration of a communication karaoke system. The communication karaoke system of the embodiment includes a host computer 1 and a karaoke terminal 10 connected to the host computer 1 by a telephone line 3.

The host computer 1 is also connected to a database 5 of musical sound data for karaoke performance including new music. Karaoke terminals 10 are installed all over the country, and each terminal further comprises a communication terminal 20 and a performance terminal 30.

The communication terminal 20 is constantly connected to the host computer 1 through the telephone line 3, and has a communication means 21 for communicating with the host computer 1 and the performance terminal 3.
Interface unit 22 for exchanging data with 0
And a temporary storage unit 23 for temporarily storing the new musical score data received by the communication unit 21 and the usage status data received from the performance terminal 30 via the interface unit 22,
It comprises a communication control unit 24 for controlling these.

The performance terminal 30 is constructed so that it can be connected / disconnected to / from the communication terminal 20, and an interface section 31 for exchanging data with the communication terminal 20 and musical tone data for storing a large number of musical tone data for karaoke performance. Storage 32
And a tone conversion means 33 for converting the tone data into a karaoke voice signal, an input means 34 for a karaoke user to select a song, and a usage status storage section 35 for storing the status of music selection and performance, and these. And a performance control section 36 for controlling. The performance terminal 30 is connected to the amplifier 41, the microphone 42, the speaker 43, and the monitor TV 44 so as to provide a karaoke performance.

A modem is mainly used as the communication means 21, and a storage device such as a hard disk is used as the temporary storage unit 23, the musical sound data storage unit 32, and the usage status storage unit 35. Further, the temporary storage unit 23 uses a storage device having a smaller capacity than the tone data storage unit 32 and the usage status storage unit 35. This is because using a storage device having the same capacity requires a storage capacity that is twice as large as that of the conventional karaoke terminal 10, which is disadvantageous.

Next, the communication control processing in this communication karaoke system will be described. 2 and 3 show the case where the musical tone data such as a new song is downloaded from the host computer 1 to the communication terminal 20 and the performance information data from the communication terminal 20 or the performance terminal 30 is downloaded to the host computer 1. It is a flowchart which shows a procedure.

In this karaoke system, communication timing is mainly for downloading new music data from the host computer 1 through the telephone line 3 at midnight when the karaoke terminal 10 is not used (S1). This communication timing is arbitrarily determined by the host computer 1 and does not take the form of regular communication. I mean,
This is because a large number of karaoke terminals 10 installed all over the country have inconsistent communication systems depending on installation locations, days of the week, etc., and are not suitable for scheduled communication.

When the communication timing with the host computer 1 is reached in this way, the communication terminals 20 installed all over the country.
First, the communication from the host computer 1 is received (S2). Then, the new musical score data is taken into the communication terminal 20 and stored in the temporary storage unit 23 (S3). Next, it is confirmed whether or not the usage status data of the performance terminal 30 is stored in the temporary storage unit 23 of the communication terminal 20 (S4), and if the usage status data is stored (S4 = YE
S), this usage data is read and transmitted to the host computer 1 (S5). This usage status data is sent from the usage status storage unit 35 of the performance terminal 30 to the communication terminal 20 and stored therein when the performance terminal 30 is separated from the communication terminal 20 and then used again. It was the data. Further, regarding the usage status data transmitted to the host side in the process of S5, the temporary storage unit 2
Erased from 3. As a result, the next usage status data can be stored in the temporary storage unit 23. If the usage status data is not stored, the process of S5 is skipped (S4 = NO).

In this way, when the temporary storage of the new music data distributed from the host computer 1 and the feedback of the usage status data of the performance terminal 30 to the host side are completed, the communication control section 24 of the communication terminal 20 then performs the performance. It is also checked whether the terminal 30 is connected (S6).
If the connection is confirmed (S6 = YES), S
The new music data received and stored in S2 and S3 is sent to the performance terminal 30 through the interface units 22 and 31 (S
7). Then, the musical tone data of the new musical score is stored and stored in the musical tone data storage unit 32 in the performance terminal 30 (S8). At this time, the new musical score data sent to the performance terminal 30 is erased from the temporary storage unit 23 of the communication terminal 20. Therefore, the communication terminal 20 can accept the next new music data.

Next, the usage status storage unit 35 of the performance terminal 30
It is checked whether or not the data regarding the usage status is stored in (S9). If the usage status data is stored (S9 = YES), the stored usage status data is read (S10). Then, the usage data is directly transmitted to the host computer 1 (S11).

When the performance terminal 30 is not connected (S6 = NO), S2 and S are stored in the temporary storage unit 23.
The new music data received and stored in 3 is retained as it is. As described above, when it is time to communicate from the host computer 1 to the karaoke terminal 10, the new music data is downloaded to the communication terminal 20, and the usage status data temporarily stored in the communication terminal 20 is transferred to the host computer 1. To be fed back. If the performance terminal 30 is connected to the communication terminal 20 at this time, the new music data from the host computer 1 is passed through the performance terminal 30 to the performance terminal 30 through the temporary storage process, and the new music data stored in the performance terminal 30 is used. The situation data passes through the communication terminal 20 and is fed back to the host computer 1.

Next, at a time other than the timing of communication with the host computer 1, the performance terminal 30 changes the communication terminal 20.
The control processing when connected to will be described. The communication control unit 24 of the communication terminal 20 performs processing as shown in the flowchart of FIG. 3 at times other than the communication timing with the host computer 1 described above.

In this process, the communication control unit 24 of the communication terminal 20 checks whether the performance terminal 30 is connected to the communication terminal 20 (S16). When it is confirmed that the connection is established (S16 = YES), the communication terminal 2
It is confirmed whether or not new music data is accumulated in the temporary storage unit 23 of 0 (S17). When new music data is accumulated (S17 = YES), this new music data is read from the temporary storage unit 23 and transmitted to the performance terminal 30 (S1).
8). This new musical score data is stored in the musical sound data storage section 32 of the performance terminal 30 (S19). Continuously playing terminal 30
It is confirmed whether or not the usage status data is stored in the usage status storage unit 35 (S20). When the usage status data is stored (S20 = YES), the stored usage status data is read out and received by the communication terminal 20 side (S21). Then, the received usage status data is stored in the temporary storage unit 23 (S22).

When the processes of S21 and S22 are performed, the performance terminal 30 is instructed to erase the usage status data. Further, the use status data fetched from the performance terminal 30 in S21 and S22 is transmitted in the processes of S4 and S5 at the next communication timing with the host computer 1.

When the performance terminal 30 is not connected (S16 = NO), the processes of S17 and thereafter are not performed. If new musical score data is not stored even though the performance terminal 30 is connected (S17 = NO), the process directly proceeds to S20. Further, if the usage status data is not stored in the performance terminal 30 (S20 = NO), S21
The following processing is not performed.

Next, the second embodiment will be described. In the above-described embodiment, the data exchange between the communication terminal 20 and the performance terminal 30 is performed under the initiative of the communication control unit 24 of the communication terminal 20, but in the second embodiment, the performance terminal 30 is used.
The performance control section 36 side is configured to perform it.

Therefore, the processing flow of the communication timing with the host in the second embodiment is as shown in FIG.
Then, the processes corresponding to S6 to S11 of the first embodiment are not performed. Then, in the performance control unit 36 of the performance terminal 30, the control processing is carried out in the procedure shown in FIG.

The performance control unit 36 of the performance terminal 30 checks whether the communication terminal 20 is connected (S31).
When it is confirmed that the connection is established (S31 = YE
S) Further, it is confirmed whether or not new music data is accumulated in the temporary storage unit 23 of the communication terminal 20 (S32). If new music data is accumulated (S32 = YES), this new music data is read from the temporary storage unit 23 and received (S).
33). Then, the new musical score data is stored in the musical sound data storage unit 32 (S34). At this time, for the communication terminal 20,
The storage of the new music data in the temporary storage unit 23 is erased, and the next new music data is restored to a storable state.

Next, it is confirmed whether or not the usage status data is stored in its own usage status storage unit 35 (S35). If usage data is accumulated (S35 = YE
S), read this accumulated usage status data,
It transmits to the communication terminal 20 side (S36). At this time, it is further confirmed whether the communication terminal 20 is in communication timing with the host (S37). When it is the communication timing (S37 = YES), the transmitted use situation data is immediately transmitted to the host computer 1 through the communication terminal 20 (S38). On the other hand, when it is not the communication timing (S37 = NO), the usage status data is stored in the temporary storage unit 23 (S39). Note that S36
When the above process is performed, the transmitted usage status data is deleted from the usage status storage unit 35.

Next, a third embodiment will be described. In each of the above-described embodiments, if the communication terminal 20 and the performance terminal 30 are left in a disconnected state for a long time, new score data may not be downloaded to the performance terminal 30 or the performance terminal 3 may not be downloaded.
There is a possibility that the usage status data in 0 is not transmitted to the host computer 1. Therefore, in the third embodiment, the performance controller 36 of the performance terminal 30 is provided with the following functions.

That is, as shown in FIG. 6, the performance control unit 36 of the performance terminal 30 measures the elapsed time after being disconnected from the communication terminal 20, and after a certain time elapses, the buzzer sounds or the lamp is turned on. It blinks to inform the communication terminal 20 that it is time to connect (S41 to S43). In addition, as shown in FIG. 7, the amount of usage data accumulated after being separated from the communication terminal 20 is confirmed, and when a certain amount of usage data is accumulated, a buzzer sounds or a lamp blinks. And informs the communication terminal 20 that it is time to connect (S51 to S53). As a result, the communication terminal 2
Since the new music data is temporarily stored in 0 for a long time, the value of the new music is lost, or the storage capacity of the temporary storage unit 23 exceeds the limit and the new music data cannot be stored, and the new music data is stored in each performance terminal 30. It is possible to prevent the delivery of the data from being leaked or the feedback of the usage status data to the host from being leaked.

Whether or not the new musical score data is stored in the temporary storage unit 23 from the communication terminal 20 is transmitted to the performance terminal 30 wirelessly or the like, and whether the new musical score data is distributed as shown in FIG. It is also possible to confirm whether or not there is a delivery, display that fact, prompt the connection, and make the buzzer sound after a predetermined time elapses without the connection being made (S61 to S64).

Next, a fourth embodiment will be described. Fourth
The embodiment relates to a system in which a plurality of performance terminals 30 are connected to one communication terminal 20. The plurality of performance terminals 30 are identified with terminal numbers A to Z. In this system, the communication terminal 20
The following processing is performed as control in.

The communication control unit 24 of the communication terminal 20 operates as shown in FIG. 9 at a timing other than the communication timing with the host computer 1.
The process shown in the flow chart is executed. In this processing, it is checked whether or not the performance terminal 30 is connected to the communication terminal 20 (S71), and if it is confirmed that the connection is established (S71 = YES), the terminal numbers AZ of the performance terminal are identified. Yes (S72). Then, it is confirmed whether or not new music data that has not been distributed to the performance terminal is accumulated in the temporary storage unit 23 of the communication terminal 20 (S73). When undelivered new music data is accumulated (S73 = Y
ES), this new music data is read from the temporary storage unit 23 and distributed to the performance terminal 30 (S74). Then, it is temporarily stored in the storage unit 23 that it has been delivered to this performance terminal.
It is stored in a predetermined area (S75). The new music data thus distributed is stored in the musical sound data storage unit 32 of the performance terminal 30.
(S76).

The communication control unit 24 subsequently confirms whether the usage status data is stored in the usage status storage unit 35 of the performance terminal 30 (S77). If the usage status data is stored (S77 = YES), the stored usage status data is read out and received by the communication terminal 20 side (S78). Then, the received usage status data is stored in the temporary storage unit 23 in a format capable of distinguishing the terminal numbers AZ (S79).

When the distribution to all the performance terminals A to Z has been completed in the processing of S75, the new music data in the temporary storage unit 23 is erased, and the information for determining the distribution / non-distribution is also provided. to erase. When the processes of S78 and S78 are executed, the usage status data in the usage status storage unit 35 of the connected performance terminal is also deleted.

The usage status data stored in the temporary storage unit 23 in the format in which the terminal numbers A to Z can be distinguished in this way are shown in FIG.
It is fed back to the host computer 1 in the control process shown in. This process is almost the same as that of the first embodiment, and the same step numbers are given to the processes having the same contents and the description thereof will be omitted. The difference from the first embodiment is in the following points.

When the temporary storage of the new musical score data distributed from the host computer 1 and the feedback of the usage status data of the performance terminal 30 to the host side are completed, it is checked whether the performance terminal 30 is connected (S6), and the connection is established. If it is confirmed (S6 = YES), the terminal numbers AZ of the performance terminal are identified (S81). And S
The new music data received and stored in S2 and S3 is sent to the performance terminal 30 through the interface units 22 and 31 (S
7) The fact that it has been delivered to this performance terminal is stored in a predetermined area in the temporary storage unit 23 (S82). The new musical score data thus distributed is stored and stored in the musical sound data storage unit 32 of the performance terminal 30 (S8).

Next, the usage status storage unit 35 of the performance terminal 30
It is checked whether or not the data regarding the usage status is stored in (S9). If the usage status data is stored (S9 = YES), the stored usage status data is read (S10). Then, this usage status data is passed through together with the terminal numbers A to Z of the performance terminals and transmitted to the host computer 1 (S11).

As described above, according to the present embodiment, each performance terminal is identified to discriminate whether or not new music data has been distributed to prevent distribution of new music data from being missed. Feedback is separately provided to the host computer 1 for each terminal to prevent feedback from being leaked and to accurately grasp the usage status.

As a result, there is no trouble even if a plurality of performance terminals 30 of A to Z are connected to one communication terminal 20 and used, and it becomes very convenient to rent equipment. Although the embodiments have been described above, it is needless to say that the present invention is not limited to these embodiments and can be implemented in various modes.

For example, in the embodiment, the temporary storage unit 23 of the communication terminal 20 is smaller than the storage capacity of the musical sound data storage unit 32 and the usage status storage unit 35 of the performance terminal 30, but it is stored in the temporary storage unit 23 of the communication terminal 20. Similarly to the performance terminal 30, a large-capacity storage device may be used so as to store the same amount of distributed musical sound data.

[0048]

As apparent from the above description, according to the communication karaoke system of the present invention, leakage of new music data and feedback of usage status data can be prevented, and a device ahead of the performance terminal can be taken out. The effect is that you can rent it.

Moreover, according to the online karaoke system according to the second to fifth aspects, the new music data becomes obsolete and has no value, or the usage status data becomes full and the accumulation leak occurs. It is possible to prevent the occurrence of troubles due to the fact that the performance terminal can be separated. In particular, in the system according to the fifth aspect, the performance terminal user can directly know the arrival of the connection time, so that it is possible to reliably prevent such forgetting of connection.

Further, according to the communication karaoke system of the sixth aspect, lending and taking-out can be further simplified, and moreover, a new musical score is not delivered to each performance terminal and feedback of the usage status of each performance terminal is omitted. Can be prevented.
