Compressed Domain MPEG-2 Video Editing with VBV Requirement

A novel method is proposed to achieve efficient MPEG-2 video editing in compressed domain while preserving Video Buffer Verifier (VBV) requirements. Different cases are determined, according to the VBV modes of the bitstreams to be concatenated. For each case, the minimum number of zero-stuffing bits or shortest waiting time between two streams is determined analytically, so that the resulting bit-stream is still VBV-compliant. The simulation results show that the proposed method is applicable to any MPEG-2 bit-stream independent of its encoder.
