For the transcoding of pre-encoded video streams, certain useful picture statistics can be extracted from the input bit-streams to help bit-allocation. In this paper, a novel approach to estimate the picture-complexity of the transcoded output video streams from the input streams is proposed. Based on the picture complexity estimation, a bit-allocation strategy is presented for joint transcoding of multiple pre-encoded MPEG video streams. Simulation results show that our proposed algorithm can achieve better video quality compared to previously reported algorithms.
