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...http://www.google.ca/patents/US6542549?utm_source=gb-gplus-sharePatent US6542549 - Method and model for regulating the computational and memory requirements of a compressed bitstream in a video decoder
