    摘要: A method and apparatus are disclosed and described for providing hypothetical reference decoder conformance error detection. The apparatus includes a multi-pass encoder (200) for encoding pictures in a video sequence. The pictures are encoded in a first pass to determine a bit consumption of each picture, and a bit allocation is controlled during the encoding of the pictures in at least a second pass responsive to satisfying requirements for a subsequent decoding of the bitstream. The requirements relate to preventing at least one of underflow and overflow conditions in a buffer during the subsequent decoding. The bit allocation is based on the bit consumption determined in the first pass and buffer parameters. The pictures are encoded in at least the first and second passes into a plurality of bitstreams on a scene-basis such that any of the pictures belonging to a same scene are respectively encoded in a same one of the bitstreams.

The accessed information includes spatial interleaving information and sampling information. Another implementation encodes a video picture that includes multiple pictures combined into a single picture, and generates information indicating how the multiple pictures in the accessed video picture are combined. The generated information includes spatial interleaving information and sampling information. A bitstream is formed that includes the encoded video picture and the generated information. Another implementation provides a data structure for transmitting the generated information.

    摘要: A method and apparatus to define a Hypothetical Reference Decoder (HRD) for Multiview Video Coding (MVC) defines constraints for each possible interoperability point. Each combination of M views denotes an interoperability point. The principles of the present invention also allow for HRD constraints to be defined for a set of interoperability points and other sets are derived from the defined set. The method also allows for the HRD rules of the interoperability points to be derived from information in the bitstream syntax.
