    摘要: There are provided methods and apparatus for video stream splicing. An apparatus includes a spliced video stream generator for creating a spliced video stream using hypothetical reference decoder parameters. Another apparatus includes a spliced video stream generator for creating a spliced video stream that prevents decoder buffer overflow and underflow conditions relating to the spliced video stream by modifying standard values of at least one hypothetical reference decoder related high level syntax element.

    摘要: At least one disclosed method and apparatus relate to inter-view prediction with different resolution reference picture. A particular method includes accessing at least a portion of an encoded picture (614), the encoded picture being from a particular view of multiple views, and the portion being encoded at a particular resolution. The method further includes determining a particular view level based on the particular view (614), determining the particular resolution based on the particular view level (606), and decoding the portion based on the particular resolution (630).

    摘要: Spatial concealment of errors in an intra picture comprised of a stream of macroblocks is achieved by predicting the missing data in a macroblock based on an intra prediction mode specified in neighboring block. In practice, when macroblocks within a stream are coded by a block based coding technique, such as coding technique specified in the H.264 ISO/ITU standard, a macroblock can be predicted for coding purpose based on neighboring intra prediction modes specified by the coding technique.

    摘要: There are provided methods and apparatus for transform selection in video coding. An apparatus includes a video encoder for encoding at least a block in a picture by selecting a transform to apply to a residue of the block from a set of two or more available transforms. The transform is selected based on at least one of an inter prediction mode used to predict at least one reference for the block, one or more values corresponding to a motion vector, a value of a residue of one or more previously encoded blocks, a value of prediction data for the block, one or more transform selections of one or more neighboring reconstructed blocks, and a quantization step applied to transform coefficients for the residue of the block.
