    摘要: There are provided scalable video encoder and decoders, and corresponding scalable video encoding and decoding methods. A scalable video encoder includes an encoder for encoding a block in an enhancement layer of a picture by applying a same weighting parameter to an enhancement layer reference picture as that applied to a lower layer reference picture used for encoding a block in a lower layer of the picture. The block in the enhancement layer corresponds to the block in the lower layer, and the enhancement layer reference picture corresponds to the lower layer reference picture. The scalable video decoder includes a decoder for decoding a block in an enhancement layer of a picture by applying a same weighting parameter to an enhancement layer reference picture as that applied to a lower layer reference picture used for decoding a block in a lower layer of the picture. The block in the enhancement layer corresponds to the block in the lower layer, and the enhancement layer reference picture corresponds to the lower layer reference picture.

    摘要: There is disclosed a video encoder and corresponding method for encoding video data for an image block. The video encoder performs a mode decision by performing initial motion estimation on only a subset of possible block sizes to output motion information corresponding thereto, and determining, based upon the motion information corresponding to only the subset of possible of block sizes and upon other image-related analysis data, whether other block sizes are to be evaluated.

    摘要: There are provided methods and apparatus for stereoscopic video coding using scalable video coding. A scalable video encoder includes an encoder (100) for encoding at least two views corresponding to multi-view video content by, encoding a particular view of the at least two views as a base layer, and encoding each of at least one other view of the at least two views as an enhancement layer using a prediction from a lower layer corresponding to at least one of the particular view and the at least one other view. The at least two views are encoded based on a selection from among at least two of temporal, spatial, and signal to noise ratio scalability techniques.

    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.
