Abstract
In a system for the transmission of video signals digitized by means of differential pulse code modulation, the constituent signal words are submitted to a variable-length coding operation. A further bit rate reduction is then realized in that the allocation of the code words to the signal words is periodically adapted to the local statistics of the video signal.
