COMPRESSION RATE CONTROL SYSTEM AND METHOD WITH VARIABLE SUBBAND PROCESSING

摘要

A system, method, and computer program product provide finer rate control in data compression by processing a data stream (201) tliroug a plurality of parallel subbands wherein a first subband processes the data differently than a second subband. Separate shift quantization (204) parameters can be provided for each subband. The parameter value can be recorded in the compressed output file (208).
