ABSTRACT:
An apparatus, system, and method for compressing and coding audio and/or video data by the MPEG2 system or the like, multiplexing the same, and transmitting the resultant data via a digital line. When generating a transport stream for transmitting a PES packet of the MPEG2 system, the amounts of the compressed video data and the compressed audio data are defined as whole multiples of the amount of the transport packet (188 bytes) of the MPEG2 system, thereby to bring the boundary of the frame cycle of the audio and/or video data and the boundary of the transport packet into coincidence. Where the amount of data is arbitrary, calculation etc. of the offset value which becomes necessary at the scheduling is made unnecessary.
