Abstract

Progress of technology in recent decade causes that video transmission via communication
channels has met high demands. Therefore, several methods have been proposed to improve the
quality of video under channel errors. The aim of this paper is to increase PSNR for synthesizedvideo
by increasing channel encoder rate but in constant transmission rate.This is achieved by using
intelligent neural network and Huffman used in the MPEG standard to compress transmitted data
significantly. Then,depending to the amount of compression by the proposed method, the compressed
data is coded again using secondary channel encoder. The proposed method is able to increase
channel coding rate without increasing the amount of information for each 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 state-of-the-art methods.
