METHOD AND APPARATUS FOR SCALABLE VIDEO ENCODING, METHOD AND APPARATUS FOR SCALABLE VIDEO DECODING

摘要

PURPOSE: A scalable video encoding and decoding method and an apparatus for the same are provided to efficiently transmit diverse scalable extension type information applied when encoding a video while being compatible with various video compression methods. CONSTITUTION: A bitstream is generated by encoding a video according to at least one predetermined scalable extension type among multiple scalable extension types (S910). Scalable extension type information indicating a scalable extension type of an encoded video is added to the bitstream (S920). The scalable extension type information includes table index information indicating one scalable extension type information table of multiple scalable extension type information tables which define available combinations of the multiple scalable extension types and layer index information indicating the scalable extension type of the encoded video among the combinations of the multiple scalable extension types included in the scalable extension type information table.
