Paper Abstract

In this paper, we propose a novel scalable video coding algorithm based on adaptively weighted multiple reference frame method. To improve the coding efficiency in enhancement layer, double reference picture and double motion vector algorithms are employed for motion compensated prediction. In addition, the enhancement layer is predicted by the adaptively weighted sum of the double motion compensated frames in the enhancement layer and the the current frame in the base layer, according to the input video characteristics. By employing adaptive reference selection scheme at the decoder, the proposed method can reduce the drift problem significantly. experimental results show that the proposed algorithm yields higher PSNR performance compared with the fixed weighted scheme and the H.263+ for various packet loss rate channel conditions.
