Video transcoding performs the operations such as bit rate and layout alteration to transform one compressed video stream to another. Transcoding enable multimedia devices of diverse ability and formats to restore video content on various platforms. Modern multimedia applications have become popular because of the most advanced multimedia compression techniques. Concentrated efforts on 4-D perceptual quantization modeling predict the frame complexity but suffer from the time varying packet loss rate and fluctuating bandwidth. To overcome the packet loss, a Single and Compound Report Transcoding Method, is presented. In single report mode, Subject Prioritized Retransmission (SPR) method is evolved, to mitigate the error propagation due to packet loss in video transfrr. The SPR method resolves the retransmission schedule of a lost packet according to the packet's loss impact that is obtained in a front end encoding process. In compound report mode, Channel Alert Compound Report Transcoding method is introduced, that reduces the error propagation due to packet loss caused by transient channel switching.
