Abstract
In a signal transmission chain containing, for example MPEG2 coders (12, 20, 28) and decoders (24, 30), an information channel extends throughout the signal chain. Signal processing elements in the chain take advantage of information (VP) on the information channel and also add to it information (VP) concerning the process performed by that signal processing element. The information channel, towards the end of the signal transmission chain, therefore carries information (VP) relating to all or most of the various processes performed by in the chain.
