AB  - 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 4D Perceptual Quantization modeling (PQrc) 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. Moreover, an adaptive error control scheme is developed with the 
  proposed method to initiate error flexibility features in a compressed video 
  which provide more flexibility to the roaming clients. The proposed transcoding 
  method divides the error control operation into single report and multiple or 
  compound report modes according to the availability of the channel. In single 
  report mode, Subject Prioritized Retransmission (SPR) Method is evolved to mitigate 
  the error propagation due to packet loss in video transfer. 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 (CA-CRT) Method is introduced 
  that reduces the error propagation due to packet loss caused by transient channel 
  switching. The experimental evaluation of single report and compound report 
  transcoding method is compared with the 4D Perceptual Quantization (PQrc) Modeling 
  in terms of PSNR, accuracy, packet loss rate and provides better bandwidth and 
  results evaluate that the packet loss rate is reduced to 3.57%.
