Title
QoS Improvement for H.264 Video Transmission Based on Structural Similarity
Abstract
In this paper, we proposed a novel algorithm to improve the service quality of H.264 video transport stream over a congested DiffServ network. The video packets are first pre-marked in the application layer during encoding at the sender end, where the importance of pre-marking is set according to the non-structural similarity of video contents. Next, the control of traffic flow is marked with colors according to the video pre-marking and the network conditions, with each color given different drop precedence in order to reduce the possibility of losing important video packets. At the receiver, we use frame copy method to conceal the errors if packet drop is happened. The performance is simulated and verified by the use of NS-2 network simulator. It shows that the quality of video transmission is improved.
