N2 - Progress of technology in recent decades causes that video transmission via communication channels has met high demands. Therefore, many methods have been proposed to improve the quality of video under channel errors. The aim of this paper is to increase PSNR for video reconstructed by the receiver; this is achieved by increasing channel encoder rate but in constant transmission rate. In the proposed method the video frames’ parts containing more energy are coded by local channel coding inside source encoder. Then, the resulted data is embedded in low power frames’ parts. The proposed method is able to increase channel coding rates without increasing the amount of information for any frame. This method provides more robustness for video frames against channel errors. The proposed method is tested for different source coding rates and several SNRs for channel and the obtained results are compared with a new method.
