Method of multiplexing digital signals

摘要

A multiplexed bit stream consists of interleaved words all of the same number of bits, the words corresponding to respective channels one of which is a synchronizing channel. A predetermined one of the bits of the words is used to identify the synchronizing channel, and may be used in the other, information, channels to carry service-related overhead and signalling information. The bit rate of the multiplexed bit stream is a harmonic of the bit rate of the individual channels. Such but streams can be further multiplexed together in a word-interleaved harmonic manner, whereby a harmonic structure of signals at different levels of multiplexing is built up.
