Abstract:
A method of controlling a data compression assembly having several data-compression channels (DCC), a data-compression channel (DCC) comprising:a data compressor (CMP) for compressing input data (D) so as to obtain compressed data (Dc); a buffer-memory space (BUF) for temporarily storing the compressed data (Dc) and for providing the compressed data (Dc) in the form of an output data stream (DS); characterized in that the method comprises the steps of: establishing indications (IND) of compressed-data quality (Q[Dc]) versus extent of compression (E[CMP]) for respective data-compression channels (DCC); partitioning (JBRC) a total output bit rate (Rtot) over respective output data streams (DS) in dependence on the indications (IND); controlling (CON) the extent of compression in respective data-compression channels (DCC) individually on the basis of output data stream bit rate (R) and amount of compressed data (F) stored in the buffer memory space (BUF).
