REGULATION OF COMPUTATIONAL AND MEMORY REQUIREMENTS OF COMPRESSED BITSTREAM IN VIDEO DECODER

摘要

PURPOSE: Present invention relates to method and model for controlling memory requirement and compressed bitstream calculation in a video decoder. And present invention is particularly useful in audio-visual coding and compression technology for controlling complexity requirement of bitstream. CONSTITUTION: An apparatus for the verification of compressed objected-oriented video bitstream includes a set of verifier models: Video Complexity Verifier (VCV), Video memory Verifier (VMV) and Video Presentation Verifier (VPV). The models specify the behavior of a decoder for variable VOP size and rate and define new parameters and bounds to measure and verify the computational and memory resources that the bitstream demands. They can be used in the video encoder or in the verification of pre-compressed video distribution.
