FIG. 3 is a diagram showing an example of music data and ICM data. FIG. 1A shows the configuration of the entire music data, and FIG. 1B shows the configuration of a melody track in a musical sound track as an example of a track. The music data includes a header, a musical sound track, a lyrics track, a voice control track, and a DSP control track. The header is a portion in which various data related to the music data is written, and includes data such as a music title, a genre, a release date, and a music performance time. The hard disk storage device 17 stores approximately 10,000 music data, and each music data is identified by a music number.

Each of the musical sound track, the lyrics track, the voice control track, and the DSP control track is described in the MIDI format shown in FIG. The MIDI format is originally a format for describing data for musical tone control such as a musical tone track. However, since all data is described in a unified format, tracks other than the musical tone track are also described in the MIDI format. A track in the MIDI format includes a plurality of event data and duration data indicating the timing of each event data. When performing a karaoke song performance, the plurality of tracks are read out in parallel. In each track, the value of the timing data is counted by a predetermined tempo clock, and when this value is counted up, the event data indicated by the timing data is read. The read event data is output to a predetermined operation unit, and a corresponding process is executed in the operation unit.

The musical sound track is composed of a plurality of parts such as a melody track and a rhythm track. The event data of the musical tone track includes note-on event data for instructing the generation of musical tones and note-off event data for instructing the silencing of musical tones. , Note number indicating the pitch, velocity, etc. These event data are input to the sound source 19.

The event data of the lyrics track includes a character code of the lyrics to be displayed on the monitor 29, coordinate data indicating a display position, display color data, and the like.

The event data of the audio control track is data indicating audio data included in the music data. When the event data is read, the audio data indicated by the data is sent to the audio data processing unit 20. Is entered. The voice data is ADPCM data of a human voice such as a back chorus or harmony singing that is difficult to synthesize by the sound source 19.

The event data of the DSP control track is
This is data for setting the type and degree of an effect given to the tone signal by the DSP 21, and is input to the DSP 21.

FIG. 2C is a diagram showing the structure of ICM data. Since the reproduction of the ICM data is performed using the same functional units (sound source 19, audio data processing unit 20, pattern development unit 26, etc.) as the performance of the karaoke music, the ICM data has almost the same configuration as the music data for the karaoke performance. It has become. That is, the BGM track corresponds to a musical sound track of the music data, the display track corresponds to a lyrics track of the music data, and the announcement control track corresponds to a voice control track of the music data. The ICM video data is for reproducing the video displayed on the monitor 29 when the ICM data is reproduced. Since the information content of the ICM data and the video correspond one to one, the video data is converted to the ICM data. Included. If a song number is written as BGM designation data instead of the BGM track, song data identified by the song number can be read and played as BGM.

At the time of reproducing the ICM data, the reading of each track is performed in the same manner as the performance of the karaoke music based on the music data. When the event data of the display track is read, the data is transferred to the pattern developing unit 2.
6 to expand into character patterns of information or advertising. This character pattern is superimposed on a video obtained by decompressing and reproducing the ICM video data, and
9 is displayed.

When the event data is read from the announcement control track, the audio data specified by the event data is input to the audio data processing section 20 and reproduced as information or the sound of an advertisement.

FIG. 4 is a flowchart showing the local ICM data input operation of the local host 4. First, an instruction to input video data is issued from the input device 5 (s1).
EG compression is performed to obtain ICM video data (s2). Next, an instruction to input an audio signal of the announcement is issued from the input device (s3), and the input audio signal is converted to an AD signal in response to the instruction.
The data is converted to PCM and used as audio data (s4). Next, an instruction is given to input character data to be displayed as text and layout data such as a display position of the character data, and these data are input (s5). Also, BGM
An instruction to input designated data is given, and BGM designated data is inputted (s6). Instead of inputting BGM designation data, MIDI format BGM track data may be input. These data are automatically edited into a predetermined format and edited into local ICM data as shown in FIG. 3C (s7). And this edited local IC
The M data is written to the local ICM data directory 17b of the communication karaoke device 7 (s8).

Although this operation has been described as an operation of the local host 4, the communication karaoke apparatus 7 may be capable of executing this processing operation by itself.

FIG. 5 is a flowchart showing the operation of the communication karaoke apparatus when the performance of the karaoke tune has ended. When the performance of the karaoke song is completed, it is determined whether there is a reservation for the next karaoke song (s11). If there is a reservation for the next karaoke song, the process proceeds to the performance operation of the reserved karaoke song without reproducing the ICM data. If there is no reservation for the next karaoke song, it is determined whether ICM data is stored in the directory of the local ICM (s1).
2) If local ICM data is stored, the local ICM data is read out (s13),
The music data designated by the local ICM data as BGM is read (s14), and the operation proceeds to the local ICM data reproducing operation. If the local ICM data is not stored, the process proceeds to the reproduction operation of the general-purpose ICM data downloaded from the distribution center 1.

With the above operation, local ICM data can be created in the local host 4 and reproduced between music pieces in each communication karaoke apparatus 7.

In the above operation, once reproduced IC
The M data is checked for reproduction, and is not repeatedly reproduced until the reproduction of all the ICM data stored in the hard disk storage device 17 is completed. Can be reproduced in order.
