Abstract

A data processing system comprises a data compression decoder arranged in operation to decode first and second encoded data to produce first and second uncompressed data representative of first and second source data from which the first and second encoded data were produced in accordance with a compression encoding algorithm respectively. The data compression decoder also produces first and second compression parameter data representative of encoding decisions made by the compression encoding algorithm when the first and second source data was compression encoded. The data processing system also comprises a data compression encoder which is arranged in operation to compression encode the uncompressed data in accordance with the compression encoding algorithm using the first and/or the second compression parameter data, and a data communications apparatus coupled to the data compression decoder and the data compression encoder and arranged in operation to communicate the first and/or the second uncompressed data and the first and/or the second parameter data, wherein the first and second uncompressed data and the first and/or the second parameter data are separately communicated via a common communications channel provided by the data communications apparatus. The compression encoding algorithm may be an MPEG-type algorithm, such as MPEG-2. The data processing system provides an advantageous alternative to the MOLE (TM).
