摘要

An image encoding method according to an embodiment of the present invention comprises: a step of writing buffer description definition information which defines a plurality of buffer descriptions to a sequence parameter set (S102); a step of writing reference list description definition information which defines a plurality of reference list descriptions which correspond to the plurality of buffer descriptions to the sequence parameter set (S103); and a step of writing buffer description selection information which specifies a selected buffer description to a first header of the processing unit which is included in an encoding bitstream (S105).
