METHOD AND APPARATUS FOR QUANTIZATION ENCODING AND DE-QUANTIZATION DECODING USING TRELLIS

摘要

The present invention provides a method and an apparatus for quantization encoding and de-quantization decoding using trellis. The present invention performs quantization encoding and de-quantization decoding by using a new index by classifying a quantization level, to which a coset is allocated, and allocating an index so as to select the coset corresponding to a specific branch at a predetermined state disposed on the trellis through only index without encoding or decoding information about a path different from a CQ index.;COPYRIGHT KIPO 2016
