Signaling buffer fullness

摘要

Techniques and tools are described for signaling hypothetical reference decoder parameters for video bitstreams, including signaling of buffer fullness. For example, a buffer size syntax element indicates a decoder buffer size, and a buffer fullness syntax element indicates a buffer fullness as a fraction of the decoder buffer size. As another example, buffer fullness is signaled in one or more entry point headers and other hypothetical reference decoder parameters are signaled in a sequence header.
