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

摘要

An apparatus for processing a signal and method thereof are disclosed. Data coding and entropy coding are performed with interconnection, and grouping is used to enhance coding efficiency. The present invention includes the steps of obtaining a difference value and index information and entropy-decoding the index information and identifying an entropy table corresponding to the entropy- decoded index information and entropy-decoding the difference value using the identified entropy table and obtaining data using a reference value corresponding to a plurality of data and the decoded difference value.
