FIELD: physics, computer engineering.SUBSTANCE: invention relates to a hypothetical reference decoder (HRD) for scalable video coding (SVC). The invention proposes to modify the H.264/AVC HRD standard for use with the SVC of advanced video coding (AVC). That implementation defines HRD constraints for each interoperability point of SVC. The changes for spatial, temporal and SNR scalability are shown. There are also changes to the related HRD parameters that are shown. 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.EFFECT: ensuring video coding compatibility.4 cl, 5 dwg |
