HIGH EFFICIENCY CODING METHOD/DEVICE AND HIGH EFFICIENCY DECODING METHOD/DEVICE

摘要

PURPOSE:To provide a high efficiency coding device which can apply the highly efficient compressing/coding processing to the data on plural channels including the band limited data on at least a single channel. CONSTITUTION:Each of coding means c1-Cn compresses and codes the signals of plural channels including the band limited signal of at least a single channel by the same means. A re-coding means 100 applies the re-coding processing to the band limited signal of at least a single channel that is compressed and coded by the means Cn in order to get rid of the redundant information produced by the band limitation.
