VIDEO TRANSCODING ARCHITECTURE WITH MINIMUM BUFFER REQUIREMENT FOR COMPRESSED MPEG-2 BITSTREAM

In this paper, an extremely efficient MPEG-2 video transcoding method is proposed, which has a low buffer requirement and results in low del ay. Most importantly, the proposed method does not need the computatio nal intensive motion estimation. Simulation results demonstrate that t he proposed approach results in very consistent video quality and main tains the buffer level effectively. Compared with direct decode/encode approach, the proposed approach only suffers slight quality degradati on. (C) 1998 Elsevier Science B.V. All rights reserved.
