摘要

PROBLEM TO BE SOLVED: To make it possible to distribute music programs outputting words and pictures in synchronization with performances of the music programs to a display of a KARAOKE device by multiplex-broadcasting a music ID and a performance progress data on a music data program. SOLUTION: Music program data into which speech signals of a music program are coded and compressed are distributed with a music ID 303b and a performance progress data 303c multiplexed on the music program data. The music ID 303b is information for identifying the music program, and while the music is on the air, the corresponding music TD is repeatedly broadcast at sufficiently short intervals. The performance progress data 303c are information for identifying which part is presently performed in the music program on the air, and the data 303c are successively broadcast at appropriate time intervals while the music program on the air. Namely, the music ID 303b and the performance progress data 303C are broadcast at regular time intervals by being inserted in the time series every time when counting a specified number of pulses for sampling the speech signal of the music program.
