Abstract
To compensate a failure in downloading of music piece data. For example, when a viewer instructs purchase of a music pieceC to an IRD at a timing t0 during the sixth transmission of music piece data, the music piece data to be transmitted for the seventh time immediately after the instruction is usually downloaded. When the downloading of the music piece data transmitted for the seventh time fails for some reason, downloading is re-executed on music piece data to be transmitted for the eighth time. The music piece data for the final transmission time in each of musical pieces is used for re-execution. Timing at which downloading of the music piece data transmitted for the time immediately preceding the final time can be instructed is set as purchase limit time by using elapsed time since program start time.
