Coding/decoding digital signals for digital images having signals block divided transferred then sub band quantized using symbol groups/construction entropic code group/code group sets

摘要

The digital signal coding and decoding process divides signals in digital blocks, transforms them into sub bands and quantizes the blocks. There is a step (E8) quantizing symbol groups, followed by construction (E18) of an entropic code for each quantized group. Each entropic code group is then coded (E19).
