In digital video compression, the output bit-streams from respective encoding means, each of which has a quantization parameter being varied between coarser and finer values in accordance with the nature of the material being encoded, are multiplexed. The allocation of bit rate amongst the respective encoding means is effected by using a measure of the relative quantization levels of the respective encoding means to select the encoding means from which data is to be read.
