Model based predictive Rate Controller for video streaming

Due to the heterogeneous structure of networks, video streaming over lossy IP networks is very important issues. Infrastructure of the Internet exhibits variable bandwidths, delays, congestions and time-varying packet losses. Video streaming applications should not only have a good end-to-end transport performance but also have a robust rate control, because of variable attributes of the Internet. Furthermore video streaming applications should have a multipath rate allocation mechanism. So for providing the video streaming service quality, some other components such as Bandwidth Estimation and Rate Controller should be taken into consideration. This paper gives an overview of video streaming concept and bandwidth estimation tools and then introduces special architectures for bandwidth adaptive video streaming. A bandwidth estimation algorithm-pathChirp, optimized rate controllers and multipath rate allocation algorithm are considered as all-in-one solution for video streaming problem. This solution is directed and optimized by a decision center which is designed for obtaining the maximum quality at the receiving side.
