Abstract
A transmission rate adjustment device for supplying MPEG-TS at a desired transmission rate includes: a buffer; a buffer write unit for both sequentially writing to the buffer transport packets of the transport stream that have been read from an MPEG2-TS file and detecting time stamps in the transport stream; and a buffer read unit for transmitting to the MPEG decoder transport packets that have been sequentially read from the buffer at a transmission rate determined by a clock obtained by frequency-dividing a system clock of the MPEG decoder by a frequency division rate designated by a frequency division rate signal. The buffer read unit not only inserts NULL packets between transport packets, but also rewrites time stamps when adjustment cannot be realized by merely inserting the NULL packets.
