2. Description of the Related Art Conventionally, as a karaoke device for business,
There has been a karaoke communication system that transmits performance data from a central device to a plurality of karaoke terminal devices. In this type of karaoke communication system, each of a plurality of karaoke terminal devices installed in an individual store or room is connected to a central device that stores data of many songs via a transmission line. When a desired song is requested from the karaoke terminal device to the central device through the transmission line, the central device transmits the karaoke data related to the request to the karaoke terminal device through the high speed transmission line. The karaoke terminal device temporarily stores the transmitted karaoke data, reproduces the data, and outputs the performance. Further, the central device accepts the next requested song from each karaoke terminal, and transmits the requested song even while the karaoke terminal is reproducing the data.

[0003]

However, in the karaoke communication system as described above, even if a high-speed transmission line is used, at least the karaoke data for one song is transferred from the central unit to the karaoke terminal unit. It takes a few seconds. If a karaoke terminal device requests the next song to the central device while one karaoke terminal device is playing a song, the central device accepts the request and then makes a request. The transfer of the corresponding karaoke data is started. When there is a first request from another karaoke terminal device after the central device accepts the request and starts transferring the karaoke data, the karaoke data is transferred to the karaoke terminal device previously requested to the karaoke terminal device. After the end, the karaoke data corresponding to the request from the karaoke terminal device is transferred. Therefore, the user of the karaoke terminal device who requested later does not have the karaoke data in the terminal device he / she uses because of the influence of the transfer of the karaoke data to another terminal device that already has the karaoke data. Nevertheless, I had to wait a very long time before the requested song started playing.

The present invention has been made in order to solve the above-mentioned problems, and transfers karaoke data to each karaoke terminal device by preferentially transferring the karaoke terminal device which does not have data for one song. An object of the present invention is to provide a karaoke communication system capable of quickly playing a desired song on a karaoke terminal device in which no song is played.

[0005]

In order to achieve this object, a karaoke communication system of the present invention is connected to a central device having data storage means for storing a plurality of karaoke data, and the central device via a transmission line. And input means for inputting the code corresponding to the desired song,

Next, the operation of the karaoke communication system of this embodiment will be described with reference to the flow charts shown in FIGS.

In the karaoke terminal device B, the terminal side main routine shown in FIG. 5 is started. First, the terminal side control means 4 detects whether or not a desired music piece is input by referring to a flag reqflag on a memory (not shown) (S1). This flag is set in the key input interrupt routine described later.

If reqflag is not set (S1: NO), S1 is repeated until it is set. If reqflag is set (S1: YE
S), and waits for the karaoke data including the performance data of the requested song and the background video data to be transmitted from the central apparatus A (S2). When the karaoke data is transmitted (S2: YES), the data is received, and the performance data and the background image data are sequentially stored in the karaoke data temporary storage means 7 (S3). Then, it is detected whether or not the reception of the data for one song is completed (S4), and if not completed (S4: NO), the process returns to S3 to continue the reception. When the reception is completed (S4: YES), the reqflag is reset and a timer (not shown) for executing a performance interrupt routine (see FIG. 7) described later is started (S4).
5) Then, the process returns to S1 again, and it is checked whether or not the desired music is input.

Designation of a piece of music desired to be performed is performed by a key input interrupt routine generated by pressing a key by a karaoke user. The operation in this key input interrupt routine will be described with reference to the flowchart shown in FIG.

First, the user of the karaoke terminal device B operates the ten-key 5a of the input means 5 to input the designated number of the piece of music desired to be played (S10). The terminal-side control means 4 generates a request code based on the inputted music designation number, displays the music designation number on the indicator 5b of the input means 5, and further, via the terminal-side communication means 6, of the central apparatus A. The request code is transmitted to the central communication means 3 (S11). Then, when the transmission is completed (S1
2: YES), the reqflag indicating that the song designating number of the desired song has been input is set (S13), and the key input interrupt routine returns to the terminal side main routine.

Next, the performance interruption routine will be described with reference to the flow chart shown in FIG.

In step S5 of the above-mentioned terminal side main routine, the performance interrupt is interrupt-driven by a timer (not shown) at regular time intervals (for example, several tens of microseconds), and musical sounds and images are reproduced by this interrupt. Therefore, the reproduction can be performed in parallel with the transmission of the request code to the central apparatus A. In the performance interruption routine, the performance data and the background video data are sequentially read from the karaoke data temporary storage means 7, and the music data of the performance data is sent to the D / A converter 8 in the musical sound conversion means 14, while In sync with
The lyrics data of the performance data and the background video data are sent to the graphic processor 12 (S20).

The D / A converter 8 converts the input music data into an analog karaoke sound signal and outputs it to the audio amplifier 9. The audio amplifier 9 amplifies the karaoke sound audio signal and outputs it from the speaker 11, and the karaoke sound is output from the speaker 11.

In parallel with this, the graphic processor 12 generates a lyrics video signal and a background video signal from the inputted lyrics data and background video data, respectively, superimposes them and outputs them to the monitor display 13. The background image a and the lyrics image b are displayed on the monitor display 13 (see FIG. 3).

The singer sings along with the performance output while referring to the lyrics displayed on the monitor display 13. The singing voice is input from the microphone 10 to the audio amplifier 9 as a singing voice signal, the karaoke sound voice signal from the D / A converter 8 and the singing signal are mixed in the audio amplifier 9, and the speaker 11 is used.
Is output from.

In each performance interruption, after S20, it is checked whether or not the karaoke data temporary storage means 7 has karaoke data of the currently playing tune (S21). (S21: YES), and return from the performance interruption routine to the terminal side main routine. If there is no data, the karaoke terminal device number, the number of the song that has finished playing, and the performance end code indicating the end of the performance are transmitted to the central device A through the terminal side communication means 6 and the transmission line C (S22), and transmitted. Is completed (S2
3: YES), the timer for executing the performance interruption is stopped, and the performance interruption routine returns to the terminal side main routine.

The other karaoke terminal device B also operates in exactly the same manner as described above.

On the other hand, the central communication means 3 of the central device A is
When receiving the request code from each karaoke terminal device B, a reception interrupt is activated for the central control means 2 at an arbitrary time. The operation of the reception interrupt routine at this time will be described with reference to the flowchart shown in FIG.

In the reception interrupt routine activated by the central control means 2, the central control means 2 checks whether the received data transmitted from the karaoke terminal device B and received by the central communication means 3 is a request code. Yes (S30). If the data is the request code (S3
0: YES), receive the request code (S3
1) The reception message is transmitted to the karaoke terminal device B via the central communication means 3 and the transmission line C.

The received request code is stored in the schedule table by the karaoke data transmission scheduling means 16 (S32). For example, in the scheduling table shown in FIG. 4A, in the karaoke terminal device B with device number 1, there is a request for karaoke data with the song designation number “53” first, and then with the song designation number “8”.
This indicates that there was a request for karaoke data of "1". Regarding the karaoke data of the song designation number “53”, the transmission flag is 1, so the karaoke data has already been transmitted to the karaoke terminal device B.
This shows that the data is being played at the karaoke terminal device B. As for the karaoke data of the song designation number “81”, since the transmission flag is 0, the transmission of the karaoke data to the karaoke terminal device B has not yet started, or is being transmitted but has not ended. It is shown that. Although not shown in the figure, if the transmission flag of the karaoke data of the music designation number "81" is 1, it means that the transmission of the karaoke data to be played next has been completed and is on standby.

On the other hand, at the karaoke terminal number 2, the song number "6
8 ”karaoke data is being played, no request has been received from the karaoke terminal device number 3 terminal, and no performance has been performed.

In this state, if there is a request for the music designation number "186" from the terminal of the karaoke terminal device number 3, in step S32, "186" is added to the song designation number A of the karaoke terminal device number 3 of the schedule table. Is recorded. Also, the transmission flag for the song designation number A includes
Since karaoke data is not transmitted at this stage, 0 is recorded (see FIG. 4 (b)). In this way, the request code from each karaoke terminal device B is set in the schedule table in S32, and the process returns to the central side main routine shown in FIG.

When the data sent from the karaoke terminal device B is not the request code in S30 (S3
0: NO), the central controller 2 determines whether the data is a performance end code (S35). If it is not the performance end code (S35: NO), the reception interrupt routine is directly returned to the main routine of the central controller 2 (see FIG. 9). When the performance end code is detected in S35, the process proceeds to S36, and the karaoke terminal device number that transmitted the performance end code and the number of the music that has finished playing are received, and the corresponding music designation number in the schedule table is deleted in S37. To be done. For example, when the karaoke terminal device B having the terminal number 2 transmits the performance end code of the song having the song designation number “68”, “68” and the transmission flag recorded in the song number A of the terminal number 2 in the schedule table. Each 1 is cleared to 0 (see FIG. 4 (c)).

At this time, for example, when the music designation number is set after the music number B as in the schedule table of the karaoke terminal device having the terminal number 1, the music number B is deleted because the content of the music number A is deleted. Contents (song number and transmission flag) are stored again in the area of song number A and song number B
In the area No., a music designation number and 0 is entered as a transmission flag.

After the song number is deleted in S37,
The reception interrupt routine returns to the central main routine shown in FIG.

The central control means 2 of the central apparatus A controls the transmission of karaoke data in the main routine shown in FIG.

First, the contents of the schedule table are searched, and it is determined whether or not there is a song that has not been transmitted despite a request (S40). For example, in the schedule table in FIG. 4 (c), the karaoke terminal devices B having the terminal numbers 1 and 3 have the song designation numbers “81” and “186”, but the transmission flag is 0, so that the transmission has not been performed. 2 songs
I know there is a song. If there is no untransmitted request (S40: NO), the detection is repeated again. If there is an untransmitted request (S40: YES), the process proceeds to S41.

In S41, it is determined which terminal number of the karaoke terminal device to transmit the requested song from among the untransmitted requests in the schedule table. For example, in FIG.
In the schedule table in (c), of the requests from the karaoke terminal device B with the terminal numbers 1 and 3, the karaoke terminal device B with the terminal number 1 is playing the song with the song designation number “53”, and Although no urgency is required, since the karaoke terminal device B having the terminal number 3 is not playing, karaoke data must be transmitted as urgently as possible. Therefore, it is decided to transmit the karaoke data of the music designation number “186” to the karaoke terminal device B of the terminal number 3.

If there are a plurality of karaoke terminal devices that are not playing and there is a request for karaoke data from each of them, for example, the karaoke data should be selected in order from the one having a smaller capacity and the karaoke data should be transmitted. You can do this.

When the song specification number corresponding to the karaoke data to be transmitted to the karaoke terminal device B is thus determined, the karaoke data storage means 1 is searched and the karaoke data corresponding to the determined song specification number (playing is performed. (Data and background video data) is read from the karaoke data storage means 1 (S42).

The central side control means 2 transmits the read performance data and background video data to the terminal side communication means 6 of the karaoke terminal device B via the central side communication means 3 and the transmission line C (S43). When transmission is completed (S44: YE
S) In the schedule table, the transmission flag of the song number for the karaoke terminal device B just transmitted is set to 1 (S45). In the above example, the transmission flag for the song number A "186" of the karaoke terminal device B having the terminal number 3 is set to 1.

When the process of S45 is completed, the process returns to S40 and the untransmitted music for the request is detected.

As described above, according to this embodiment,
When the central device A receives a request from a plurality of karaoke terminal devices B, the karaoke terminal device B which does not have karaoke data during or at the stage of performance at that stage.
Since the karaoke data corresponding to the request is transmitted with priority to, the waiting time until the performance of the requested song starts can be shortened.

The present invention is not limited to the above embodiment, and the karaoke data may be only performance data (music data and lyrics data) not including background data. Further, only music data may be used, and in this case, the graphic processor 12 and the monitor display 13 can be omitted. Also,
The format of the music data in the performance data may be score information, and in that case, the D / A converter 8 may be replaced with a synthesizer having sound sources of various musical instruments.

Further, in the present embodiment, the performance end detecting means is realized in the karaoke terminal device B, but the central device A having the karaoke data storing means 1 performs the music playing time, time count, or data length of the music. When the information about the playing time of each song can be detected in advance, the central device A can detect the end of the playing by detecting the time after transmitting the karaoke data to each karaoke terminal device B. It is possible.

Further, the central unit A and each karaoke terminal unit B
Are connected by a transmission line C, and information can be exchanged between the central device A and each karaoke terminal device B by exchanging information with each other. Therefore, the karaoke data transmission scheduling means 16
Can also be realized in the karaoke terminal device B. In this case, the karaoke terminal device B acquires the information necessary for realizing the karaoke data transmission scheduling means 16 through the transmission line C, determines which karaoke data device to transmit the karaoke data to, and outputs the result to the center. It may be transmitted to the device A.

[0054]

As is apparent from the above description, according to the karaoke communication system of the present invention, the karaoke terminal device which is not playing and has no karaoke data from the karaoke terminal device having karaoke data of one song or more. Since it is configured so that the karaoke data can be transferred preferentially to the karaoke terminal device which it does not have, when one karaoke terminal device is playing a song, the next song is played as a center song. When making a request to the device, even if another karaoke terminal device makes a request for the first time after that, there is a remarkable effect that the performance of the desired song can be started quickly.
