Video transmission through wireless channels is still a challenging problem on the limitations in bandwidth and the presence of channel errors. Video transcoding, due to its high practical values for a wide range of networked video applications, has become an active research topic. It is typically used to reduce the rate and change the format of the originally encoded video source to match network conditions and terminal capabilities. Error resilient video transcoding can insert error resilient tools in the compressed video to enhance error resilience of the video over wireless channels by inc...
