Method and apparatus for encoding and decoding multilayer videos

摘要

Provided are methods and apparatuses for encoding and decoding a bit stream in a multilayer video system in which a base layer and a higher layer use different codecs. The decoding method includes: receiving a bit stream including a higher-layer stream and a base-layer stream, the higher-layer stream including at least one of an identifier for identifying a codec for the higher-layer stream, information indicating features of the higher-layer stream, and information indicating a relationship between the higher-layer stream and a lower-layer stream; demultiplexing the higher-layer stream and the base-layer stream from the bit stream; decoding the base-layer stream; and decoding the higher-layer stream based on the identifier and the information indicating the features of the higher-layer stream.

主权项

1. A method for generating a higher-layer stream in a multilayer video encoding system in which a lower layer uses a codec that is different from a codec used by a higher layer simultaneously, the method comprising:
including, in a higher-layer stream of the higher layer, an identifier for identifying a codec to be used for decoding the higher-layer stream; and including, in the higher-layer stream, information indicating features of the higher-layer stream and information indicating a relationship between the higher-layer stream and a lower-layer stream of the lower layer.
