    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.

    摘要: In an implementation, a supplemental sequence parameter set (“SPS”) structure is provided that has its own network abstraction layer (“NAL”) unit type and allows transmission of layer-dependent parameters for non-base layers in an SVC environment. The supplemental SPS structure also may be used for view information in an MVC environment. In a general aspect, a structure is provided that includes (1) information (1410) from an SPS NAL unit, the information describing a parameter for use in decoding a first-layer encoding of a sequence of images, and (2) information (1420) from a supplemental SPS NAL unit having a different structure than the SPS NAL unit, and the information from the supplemental SPS NAL unit describing a parameter for use in decoding a second-layer encoding of the sequence of images. Associated methods and apparatuses are provided on the encoder and decoder sides, as well as for the signal.

    摘要: The present principles relate to a hypothetical reference decoder (HRD) for a Scalable Video Coding extension for a compression algorithm. One such implementation proposes to modify the H.264/AVC HRD for use with the SVC of AVC. That implementation defines HRD constraints for each interoperability point of SVC. One implementation in particular is described, but other implementations are possible and are contemplated by the present principles. The changes for spatial, temporal, and SNR scalability are shown. There are also changes to the related HRD parameters followed that are shown. The several mentioned implementations provide rules for an HRD for SVC. At least one implementation proposes the SVC-HRD rules as modifications to the AVC-HRD rules. A user may use the proposed SVC-HRD rules to build an SVC-HRD and test a bitstream for SVC compliance.

    摘要: Implementations are provided that relate, for example, to view tiling in video encoding and decoding. A particular implementation accesses a video picture that includes multiple pictures combined into a single picture, and accesses additional information indicating how the multiple pictures in the accessed video picture are combined. 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.
