Optimized Strategy and Implementation of AVS Video Layered Re-transmission
Donghuan Liu · Jisuanji gongcheng · 2009
Aiming at AVS video stream transmission on the Internet becomes a new focus. However, factors such as network jitter will bound to affect image quality. In this paper, the restoration technology of the error control and congestion control are combined to be produced. The technology of AVS video data RTP packing is improved in the transmission layer. The strategy of AVS video layered transmission is proposed to improve the efficiency of re-transmission and the way of token payment which can control the time of data packets re-transmission is used to solve the network congestion problem led by re-transmission. Experimental results show that: in the low-bandwidth network, this policy for AVS video transmission has a better image quality than that of delivering without token.
