METHOD AND APPARATUS FOR SIGNAL PROCESSING, ENCODING AND DECODING METHOD AND APPARATUS THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a method and apparatus for signal processing, capable of optimizing the efficiency of signal transfer.SOLUTION: Data coding and entropy coding are performed with interconnection, and grouping is used to enhance coding efficiency. The method for signal processing includes the steps of; obtaining one group reference value corresponding to a plurality of data included in one group, and a difference value corresponding to the group reference value, through data grouping and internal grouping for the data grouping; and obtaining the data by using the group reference value and the difference value.
