hrd descriptor design and data flow buffer model for hevc extension transport

摘要

a video processing device obtains a data stream comprising a plurality of elementary streams and a high efficiency video coding timer (hevc) and hypothetical reference decoder descriptor (hrd). the hevc timer and hdr descriptor comprises a delivery schedule index syntax element. The video processing device can identify, based on a set of parameters, a syntax element in a syntax element array in a video parameter set (vps). The parameter set may comprise a parameter having a value equal to a value of the target programming index syntax element. The video processing device may identify, based on the index specified by the identified syntax element, a particular hrd parameter syntax structure in a plurality of hrd parameter syntax structures as being applicable to a particular elementary stream.
