Abstract
A system for transmitting sequences of digital samples encoded by variable-length binary words is formed on the one hand by a transmitter device comprising a statistic encoding circuit for encoding in said variable-length words words of a fixed length appearing at its input in the shape of sample sequences, a synchronizing circuit for forming synchronizing words which define the position of the variable-length words in the sequences and a multiplexer circuit for combining, in view of their transmission, the synchronizing words with the variable-length words, and, on the other hand, a receiver device comprising a demultiplexer circuit for applying from one of its two outputs the variable-length words received to a statistic decoding circuit for recovering the fixed-length words and for applying from the other output the synchronizing word to a processing circuit for restituting, in the event of a transmission error, the position of the samples in the sequence.
