Abstract  Abstract

A video encoder sends video parameter comprising a plurality of hypothetical reference decoder parameter syntax structure HRD VPS for collecting signal in the encoded video bitstream the plurality of hypothetical reference decoder HRD parameter syntax structures each comprises a HRD parameter. syntax elements of a common set of HRD parameter syntax structure for each respective said plurality of HRD parameter syntax structure further comprises an indication of the VPS in the HRD parameter syntax structure than the respective HRD parameters specific to the encoded video bit stream of a specific sub-layer sub-layer specific set of HRD parameter information whether but also includes HRD parameters. is the same for all sub-layers of the common set of HRD parameters for the encoded video bit stream. A video decoder or other device from the encoded video bit stream decoding the VPS and using the syntax structure HRD parameters of at least one of the HRD parameters to perform operations.

A video encoder signals in an encoded video bitstream a video parameter set (VPS) that includes a plurality of Hypothetical Reference Decoder (HRD) parameter syntax structures that each include HRD parameters. For each respective HRD parameter syntax structure in the plurality of HRD parameter syntax structures the VPS further includes a syntax element indicating whether the HRD parameters of the respective HRD parameter syntax structure include a common set of HRD parameters in addition to a set of sub-layer-specific HRD parameter information specific to a particular sub-layer of the encoded video bitstream. The common set of HRD parameters is common to all sub-layers of the encoded video bitstream. A video decoder or other device decodes from the encoded video bitstream the VPS and performs an operation using the HRD parameters of at least one of the HRD parameter syntax structures.
