Abstract :
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 bit-streams 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
