The ROM 11 stores a system program, a loader, an application program, a self-diagnosis program, font data, and the like. The system program is a program for controlling the basic operation of this device and the operation of peripheral devices. The loader is a program for downloading music data from the center. As the application program, a peripheral device control program, a sequence program, and the like are stored. The sequence program consists of a main sequence program, a tone sequence program, a character sequence program,
It consists of an audio sequence program and a DSP sequence program. During a karaoke performance, each sequence program is processed in parallel by the CPU 10,
Generation of a musical sound and reproduction of a video based on the music data are performed. The self-diagnosis program is a program that performs a test operation of the HDD 15 and peripheral devices at a timing other than during karaoke performance or download, and confirms whether the HDD 15 or the peripheral device operates normally. For example, a read test is performed on the HDD 15 to read whether or not the contents of all the tracks can be read normally. The font data is for displaying lyrics, song titles, and the like, and stores fonts of a plurality of types of characters, such as a Mincho font and a round Gothic font. In the RAM 12,
A work area is set.

As shown in FIG. 1, a music data storage area, a CM data storage area, and a log area are set in the HDD 15. Hundreds to thousands of music data are stored in the music data storage area. Music data includes headers, music tracks, lyrics tracks, audio tracks, DS
It consists of a P control track and an audio data section. In the header, data such as the music code and the music title are written. The musical sound track is composed of sequence data for driving the tone generator 20. The lyrics track is composed of sequence data for driving the character display unit 23 to display lyrics. The audio track is composed of sequence data for controlling the reading of the audio data section. The audio data section is ADPCM data such as a back chorus or sound effect that cannot be synthesized by the sound source device 20. The audio data is input to the audio decoder 21 and P
It is converted into CM data. The DSP control track comprises a sequence track for controlling the effect of the DSP 22. A plurality of pieces of CM data are stored in the CM data storage area. The configuration of the CM data is the same as that of the music data. In the log area, the operation history of the karaoke apparatus is recorded in chronological order. The contents recorded as a log are as follows.

[0013] Song code of the played karaoke song, end time or billing time CM code of the commercial that was broadcast, end time Error information Error during reproduction Module error of sound source device 20 etc. Information destruction of system software Information destruction of hardware Data destruction information Self-diagnosis result Communication errors found during communication are not recorded in the log because they are resent immediately. However, since the communication needs to be performed in the minimum necessary time, the error check is not complete, and music data containing an error may be downloaded. This is recorded as a data error during karaoke performance.

The ISDN controller 16 is a controller for communicating with the center via an ISDN line. The music data is downloaded from the center. The ISDN controller 16 has a built-in DMA circuit, and writes downloaded music data directly to the HDD 15 without passing through the CPU 10. The content of the log is uploaded from the karaoke apparatus to the center.

The remote control receiver 17 is a circuit for receiving an infrared signal transmitted from the remote control 30 and restoring data. The remote controller 30 includes a music selection switch, a numeric keypad, and the like, and transmits an infrared signal in response to the switch-on. The display panel 14 is provided on the front of the karaoke apparatus, and displays the currently playing music code and the number of reserved music. When a log display command is input, the contents of the log are displayed. The panel switch 15 is provided on a front operation unit of the karaoke apparatus, and includes a music code input switch, a key change switch, and the like.

The tone generator 20 forms a tone signal based on music data. The audio decoder 21 receives the audio data, which is ADPCM data, and decodes it into an audio signal (digital data). The digital tone signal and audio signal output by the sound source device 20 and the audio decoder 21 are DS
Input to P22. A microphone 27 is connected to the DSP 22. The signal from the microphone 27 is converted into a digital signal at the input unit. The DSP 22 is a sound source device 2
0, effects such as reverb and echo are applied to the tone signal and the audio signal input from the audio decoder 21 and the microphone 27. The CPU 10 instructs the kind and degree of the effect given by the DSP 22 based on the DSP control data included in the music data. The DSP 21 controls the type and degree of the effect based on this data. The tone signal and audio signal to which the effect has been added are mixed and converted into analog signals, and then output to the amplifier / speaker 26.
The amplifier / speaker 26 amplifies this signal and emits sound.

The character display unit 23 generates character patterns such as song titles and lyrics based on the input character data. The LD changer 24 reproduces the background video of the corresponding LD based on the input video selection data (chapter number). The character pattern and the video data are input to the display control unit 25. The display control unit 25 superimposes these data in superimposition and displays them on the monitor 28. At the start of the karaoke performance, the CPU 10 reads the genre data of the music from the header of the music data. CPU
10 determines which background video is to be reproduced from the genre data, and outputs video selection data for selecting the background video to the LD changer 24. The LD changer 24 contains about five (120 scenes) laser disks, and can reproduce background images of 120 scenes. One background video is selected from among them according to the video selection data. In addition, also at the time of CM broadcasting, display of characters and display of background images are performed based on the CM data.

FIGS. 2 to 4 are flowcharts showing the operation of the karaoke apparatus.

FIG. 2 shows a normal operation routine. First, it is determined whether or not there is music selection at n1. If there is a song selection, the operation proceeds to the operation of n2 or less in order to play the song in karaoke. If there is no song selection, the operation proceeds to n10 or less in order to broadcast the CM using the interval. In n2, the music data of the selected music is taken into the ROM 12 from the HDD 15.
At n3, it is determined whether or not the capturing is normally performed (n3). If the music data is not read normally, it is considered that the content of the music data is broken or the HDD 15 is hardly broken, so that the abnormal content is recorded in a log (n10). . Since this music cannot be played, the performance of this music is canceled and the process returns to n1. If the reading of the music data is normally performed, the karaoke performance of the music is started (n
4). Since you may notice that you have selected the wrong song after the karaoke performance has started,
Until 0 seconds have elapsed, cancellation of the performance of the music is accepted (n5, n6). If canceled before the elapse of 30 seconds, that fact is recorded in a log (n1
1) Return to n1. If 30 seconds have elapsed without being canceled (n6), it is determined that the performance of this song is valid, and accounting information for the performance of this song is recorded in a log (n7). Thereafter, it is determined at n8 whether the karaoke performance has ended normally. If the karaoke performance has ended normally, the music code and end time of the karaoke music are stored in a log (n9). Based on this, the number of times the tune has been played is stored and stored. On the other hand, if the karaoke performance has not ended normally, the fact that the karaoke performance has not ended normally is stored in the log (n12).

If there is no karaoke song selection input, the CM is broadcast using the free time. First, one of a plurality of CM data is selected (n1
3). This CM is read out from the HDD 15 and broadcasted (n14), and it is monitored whether or not there is a music selection input (n1).
5). When a music selection is input, even if the CM is being broadcast, the operation is interrupted and the karaoke performance is started (n15 → n).
2). In addition, when the broadcasting of the CM ends without interruption, a log including the identification code of the CM and the end time is recorded (n16 → n17). In the case of the CM, the broadcasting fee is charged to the advertiser based on the number of times of broadcasting, so the number of times that the CM can be broadcast to the end without interruption is counted. Thereafter, the next CM is selected (n18) and the process returns to n14.

FIG. 3 is a flowchart showing the music selection operation. The music is selected by operating the remote controller 30. First, when the music selection switch is turned on, this operation starts. The user inputs a music code following the music selection switch. The remote control receiver 17 receives this music code (n20). If the received code is a correct music code, the music code is stored in the performance waiting register (n21).
→ n22) Return. If the song code is not correct,
Return after warning that it is not correct (n2
3). The warning indicating that the music is incorrect is displayed on the monitor 28 to indicate that an incorrect music code has been input.

FIG. 4 is a flowchart showing a self-diagnosis operation, a log transmission operation, and a log display operation. Each is executed when a self-diagnosis command, a log transmission command, and a log display command are input. In FIG. 13A, when a self-diagnosis command is input, a self-diagnosis operation is performed (n30). The self-diagnosis command can be input by an operator from the operation panel, or the center can transmit the self-diagnosis command.
The self-diagnosis operation includes a read test of the HDD 15 and an operation test of peripheral devices. The result of this operation is recorded in a log (n31). When a log transmission command is received in FIG. 4B, the contents of the log are transmitted to the center (n4).
0). The log transmission command is transmitted from the center. When the contents of the log are transmitted to the center, the center examines the contents and determines maintenance or the like. When a log display command is input in FIG. 10C, the contents of the log are displayed on the display of the operation panel (n50). The log display command is input by operating a key switch on the operation panel. By displaying the contents of the log on the display, the maintenance staff can accurately determine the location of the abnormality, and efficient maintenance can be performed.
