PICTURE DELIMITER IN SCALABLE VIDEO CODING

摘要

The use of a picture delimiter that is contained in a NAL unit type value that is reserved in the current AVC or SVC specification. The present invention provides the scalability information for the H.264/AVC base layer in such a manner that bitstreams remain decodable with H.264/AVC decoders. In addition, the picture delimiter of the present invention may contain many other syntax elements that can help in easier processing of bitstreams compared to the plain H.264/AVC bitstream syntax.

1. A method for decoding an encoded video signal comprising:
decoding at least one picture delimiter elementary data unit included in an access unit of a scalable video coding encoded video signal, the at least one picture delimiter elementary data unit associated with a first picture decodable according to a first algorithm, the at least one picture delimiter elementary data unit precedes the first picture and is configured to be selectively ignored during the decoding of a subset of the encoded video signal in accordance with the first algorithm, the at least one picture delimiter elementary data unit includes syntax elements for a temporal level identification and a priority identifier for the first picture associated with the at least one picture delimiter elementary data unit; and utilizing information contained in the at least one picture delimiter elementary data unit for decoding a subsequent elementary data unit of the encoded video signal.
