An embodiment of a karaoke apparatus according to the present invention will be described with reference to the drawings.

1 shows a schematic diagram of an embodiment of a karaoke apparatus of the present invention. In the figure, the karaoke background image data carried by radio waves from the transmitting station 1 are transmitted to the plurality of karaoke terminal devices 3a to 3n via the communication satellite 2. Further, when a request comes in from the plurality of karaoke terminal devices 3a to 3n, the music selection request information is transmitted to the transmitting station 1 via the bidirectional communication network 4, and the performance data for the request is transmitted to the transmitting station. From (1), it is transmitted to the karaoke terminal apparatuses 3a to 3n via the bidirectional communication network 4.

2 and 3 show a system diagram of the transmitting station 1.

In Fig. 3, the karaoke performance data are stored in the performance data storage device 21. As shown in the data format diagram of FIG. 6, the performance data 30 of each song includes, for example, a genre code 31 indicating the type of the song, such as a song, and a lyrics indicating a character code or display timing of the lyrics to be displayed. Data 32 and MIDl data 33 which are transmitted to a musical instrument digital interface (MIDI) sound source device for sounding a performance sound.

The song selection request information requested by the karaoke terminal apparatuses 3a to 3n via the bidirectional communication network 4 arrives at the line control apparatus 22. The system controller 23 selects the corresponding performance data from the plurality of karaoke performance data stored in the performance data storage device 21 from this information, and performs a request through the line control device 22. To the terminal device. At this time, the system controller 23 reads the genre code 31 in the karaoke performance data 30, and counts the number of times a request is generated for each genre code and stores it in the request information storage device 24. .

As shown in the data format diagram of FIG. 7A, the background image data storage device 25 stores a plurality of genre codes 51 and karaoke background image data 52 obtained by compressing digital data for each genre code. The length of the genre code 51 and each background image data 52 is a fixed length. Here, the genre code 51 shows the corresponding genre of the video, such as a love song, for example, and corresponds to the genre code 31 contained in the performance data 30 mentioned above.

In the transmission data generating device 36, as shown in the data format diagram of FIG. 7B, the background image data 52 for each genre of FIG. 7A is divided into n blocks, and the background image data 52 for each genre. Time-division by 1 / n converts the background image data 52 of a plurality of genres into a data stream 53 which can be transmitted simultaneously. This data stream 53 is sent out to the communication satellite 2 via the transmission device 27. Each background image data 52 is transmitted from the first block 1 to the last block n in order. After that, transmission is started again from the block 1 and the background image data 52 of a plurality of genres are always sent.

Here, the data stream 53 includes a synchronization pattern 54 representing a partition of a data block, a genre code 51 representing a genre of each background image data, and each background image data 52 of one of n partitions. It consists of.

Since the background video data 52 is compressed, it is possible to send a plurality of video data in real time. However, the number n of divisions and the number of genres of the background video data 52 to be transmitted in time division at the same time are determined by the receiving side. When demodulating the background image data 52, it should be set to a value at which the data does not break.

Which genre code 51 of the plurality of background image data 52 is to be sent out depends on an instruction from the system control device 23 to the transmission data generating device 26.

Although the plurality of background image data 52 are compressed and transmitted in time division, the transmission rate is limited, so in the case of a system having many kinds of genre codes 51, the background image data 52 of all genres may be time-divided. You cannot send at the same time.

Therefore, the background image data 52 of the genre with a high request frequency is preferentially transmitted with reference to the data which counted the number of requests for each genre code stored in the request information storage device 24 mentioned above.

Next, the karaoke terminal device 3 will be described. 4 and 5 show a system diagram of the karaoke terminal device 3.

In Fig. 5, when the music selection request is generated by the operation of the operation device 401, the system controller 402 transmits the music selection request information via the bidirectional communication network 4 using the line control device 403. Send to station (1).

As a result, the corresponding performance data 30 is distributed and transmitted from the transmitting station 1 via the bidirectional communication network 4 and reaches the line control device 403. The system controller 402 discriminates the performance data 30, and the lyrics data 32 is stored in the lyrics data storage 404, and the MIDI data 33 is stored in the MIDI data storage 406, respectively.

Background image data 52 transmitted from the transmitting station 1 is received at the receiving device 405 via the communication satellite 2, and the received background image data 52 is again input to the data selector 407. .

Here, the system controller 402 refers to the genre code 31 in the performance data 30 so as to discriminate the background image data 52 of the corresponding genre from the background image data stream 53 by the data selector 407. ). The data selector 407 refers to the genre code 51 added to the beginning of each background image data 52 based on the synchronization pattern 54 in the background image data stream 53 according to this setting. The background image data 52 of the set genre is extracted and sent to the background image decoder 408.

The background image decoder 408 demodulates the input background image data 52 into a background image signal, and the background image signal is input to the image synthesizing apparatus 409.

On the other hand, the lyrics data 32 stored in the lyrics data storage device 404 stores the lyrics images installed in the lyrics image generating means 410 by the lyrics image generating means 410 based on the character code of the lyrics data 32. The lyrics video signal corresponding to the character code of the lyrics data 32 is read from one ROM to generate the lyrics video signal. The lyrics video signal is sent to the video synthesizing apparatus 411.

In the video synthesizing apparatus 409, the input lyrics video signal and the background video signal are synthesized and sent to the video display device 411 and displayed on the video display device 411.

In addition, the MIDI data stored in the MIDI data storage device 406 is converted into a voice signal in the MIDI sound source device 412, and the sound of the performance is pronounced in the voice output device 413.

In this embodiment, a genre code 51 indicating a genre is added to each background image data 52 in the data stream 53 transmitted from the transmitting station 1, but the data is not added to this genre code 51. The genre code 51 may be determined in advance for each turn of the background image data 52 on the basis of the synchronization pattern 54 in the stream 53.

In addition, although the radio wave is used for the communication means of the background image data 52 in this embodiment, you may use the communication cable by the optical fiber or coaxial cable which can fully communicate at high speed instead.

According to the present invention, the background image data is centrally managed by the transmitting station, and the background image data of a plurality of genres can be transmitted from the transmitting station to the terminal device at the same time.

Further, in the karaoke terminal apparatus, the karaoke background image can be displayed by selecting appropriately from the background image data of the plurality of genres transmitted simultaneously from the transmitting station.

In addition, since the karaoke background apparatus does not need to include a signal storage unit having a large storage capacity, the karaoke terminal apparatus can be miniaturized and inexpensive.

In addition, the karaoke background image suitable for the music tune requested from the karaoke terminal device can be automatically selected and displayed.

In addition, since the karaoke background image suitable for the genre of the tune of the requested frequency is preferentially transmitted, the user of the karaoke terminal device can be satisfied.
