ABSTRACT:
Difference signals generated by the prediction encoding process for an input digital information signal are block segmented and then quantized by an ADRC encoder as a first variable-length-code encoding means. Output data of the ADRC encoder is divided into bit planes by a bit plane encoding circuit. The ADRC encoder varies the number of bits assigned to a block corresponding to a dynamic range DR. A block to which 0 bit has been assigned is detected in each bit plane and data of the block is excluded. The resultant data is encoded by a variable-length-code encoder as a second variable-length-code encoding means and then transmitted.
