WIPO Patent Application WO/2010/041680

A1

Provided is an encoding method including: a step which checks whether a frame formed by a plurality of code words encoded by an encoding method using two minimum quantization intervals to which different two types of code words are given, respectively, contains only the two types of code words given to the two minimum quantization intervals; and a step which executes a lossless encoding for the frame containing only the two types of code words.  The codes obtained by the lossless encoding are decoded by a decoding method corresponding to the lossless encoding.
