Abstract
A system for processing a stream of digital bit sets, each related to a different subject in a passing array, and including an arrangement for compressing the bit-sets and sending the results to an utilization stage; plus: a preprocessing stage for distributing each bit set in N parallel bit-compression paths, with all input sent to a common input buffer feeding these paths and each compression path being adapted to execute a prescribed first compression to ascertain 'initial factors', and then a prescribed second compression to use the initial factors, with the second compression values selected according to 'word count' factors derived from results of the first compression, and to thus provide a prescribed time-compressed output to the utilization stage; with both compressions performed according to JPEG standards; and the second compressions performed using prescribed selected QM and Huffman table values, and with a post processor stage to accept the compressed; data as 32-bit output and funnel it down to 16-bit output presented to the utilization stage.
