PROBLEM TO BE SOLVED: To make small the capacity of a memory for buffering supplied or reproduced KARAOKE data while shortening the wait time from a request for music to the start of its play. SOLUTION: Data of respective channels are distributed in packet form according to the PES structure of the MPEG2 transport layer. An identifier PID included in a header represents a number of 0 to 31. Then video data on which the buckground video of KARAOKE is based are assigned to two channels of PID=0, 1, effect sound data of ADPCM on which an effect sound such as a back chorous are assigned to a channel of PID=2, and music data on which a KARAOKE performance is based are assigned to a channel of PID=31. Further, the music data consist of a sequence obtained by rearranging packets of respective data such as playing data, text display data, and effect sound indication data in the order of processing by a KARAOKE terminal. |
