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

摘要

A signal processing method, an apparatus therefor, an encoding and decoding method, and an apparatus therefor are provided to offer a data structure for efficiently transmitting encoded data. A data grouping part(10) acquires a group reference value corresponding to a plurality of data included in one group and a primary differential value corresponding to the group reference value through a grouping including the first grouping and the second grouping. The first to the third encoding parts(20,31,32) acquire data by using the group reference value and the primary differential value.
