Paper Abstract

FGS is a video coding scheme that can control picture quality with high scalability, but it has lower efficiency than the single layer video coding scheme because of its hierarchical structure. This paper proposes application scheme of three methods for efficiency improvement to the FGS encoder and decoder. The first method is the bit plane coding method using two bit group separation based on the distribution of a significant bit. The second method is the introduction of motion compensation estimation to the enhancement layer. The third method is a complement method to make a high quality reference picture from both the base layer and the enhancement layer. In conclusion, the proposed methods can improve the coding efficiency in the enhancement layer of conventional FGS by 2.2% and the PSNR performance of conventional FGS by 1.1dB, as well as reduce propagation of the drift error caused by low rate transmission and channel congestion. The results show that the proposed method is more efficient and more suitable for video streaming on a heterogeneous network with channel deviation.
