Abstract
A method for detecting a resynchronization marker in an encoded MPEG-4 video bitstream is provided that includes computing a first candidate resynchronization marker length based on a first version of MPEG-4 Visual and the type of a video object plane (VOP) in the video bitstream, computing a second candidate resynchronization marker length based on a second version of MPEG-4 Visual and the type of the VOP, checking the video bitstream for a first valid resynchronization marker bit sequence using the first candidate resynchronization marker length, checking the video bitstream for a second valid resynchronization marker bit sequence using the second candidate resynchronization marker length, and detecting the resynchronization marker when a valid sequence of stuffing bits is present in the video bitstream after the macroblock boundary and either the first valid resynchronization marker bit sequence or the second valid resynchronization marker bit sequence is found in the video bitstream.
