ABSTRACT:
A coding arrangement which includes a coder for variable-length encoding provided with a quality control to determine the different coding characteristics, a buffer store for receiving the coded information originating from the said coder and for recovering them at an output terminal with a fixed rate thanks to the presence of a regulating circuit. The regulating circuit uses the average quality of packets of information blocks to control a filler circuit which supplies a fill quantity of the coded information. A correction circuit supplies a corrected quality value by correcting the average quality as a function of the fill quantity.
