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： Individual pixels in an image block undergo blending with film grain from a film grain block randomly selected from among a pool of previously established film grain blocks in accordance with a luma characteristic of the image block. Prior to blending, the selected film grain block undergoes deblocking by a deblocking filter (28). Following blending, a clipper clips the individual pixels prior to display. The pool of film grain blocks is created by scaling a set of film grain patterns in accordance with at least one parameter of a film grain information message that accompanies the image block.
