Variable length coding and decoding devices for digital data

Abstract

Abstract Variable-length coding device for digital signals distributed over N parallel channels (A, B, -N) comprising, between variable-length coding means (30) and throughput regulation means (90), routing means (70) sending, after classification of the coded signals according to their lengths and a classification of buffer memories according to their states of fill, these signals towards buffer memories (90) which are all the less filled the longer the said signals. In the corresponding decoding device which receives the said coded signals grouped into data blocks accompanied respectively by an indicator of rank of the said blocks, as output from inverse quantisation means, means of routing the said blocks as a function of the indicator of rank which is respectively associated with them. …<IMAGE>…
