METHOD AND APPARATUS FOR MULTI-LAYER VIDEO ENCODING, METHOD AND APPARATUS FOR MULTI-LAYER DECODING

摘要

PURPOSE: A multilayer video encoding method, an apparatus for the same, a multilayer video decoding method and an apparatus for the multilayer video decoding method are provided to efficiently signal picture order count (POC) information used in encoding and decoding a multilayer video. CONSTITUTION: A receiving unit (91) obtains first POC information for determining a first partial value of a POC of a random access point picture which is identically set with a POC of a first random access point picture and obtains second POC information about a second partial value of a POC of a second random access point picture. The receiving unit obtains the POC of the second random access point picture using the first POC information and the second POC information. A multilayer decoding unit (92) decodes multiple multilayer image streams.
