PROBLEM TO BE SOLVED: To provide a means that generates byte clocks of a small step with a wide frequency range from a system clock. SOLUTION: The bit stream multiplexer is provided with a multiplex processing means 1 that processes one MPEG-TS input or over according to a prescribed rule, multiplexes them into one multiplexed TS and provides an output of it, an oscillation means 2 that generates a system clock being a reference of a transfer rate of the multiplexed TS outputted from the multiplex processing means, frequency synthesizer means 3 each of which generates a waveform signal repeated at an interval of an optional frequency for each input of the MPEG-TS, comparison means 4 each of which converts the waveform signal outputted from the frequency synthesizer means for each input of the MPEG-TS into a binary digital signal and provides an output of it, and a setting means 5 that gives generated frequency information to the frequency synthesizer means. The byte clocks synchronously with the system clock and having a small step difference are generated. |
