An End-To-End Architecture for Mpeg-4 Video Streaming over the Internet

It is a challenging problem to design an e cient MPEG-4 video delivery system that can maximize the perceptual quality while achieving high resource utilization. This paper addresses this problem by presenting an architecture of transporting MPEG-4 video over the Internet, which includes an end-to-end feedback control algorithm and a source encoding rate control algorithm. Our feedback control algorithm is capable of estimating the available bandwidth in the network based on the feedback information from the receiver, while our source encoding rate control algorithm is able to adjust the encoding rate of MPEG-4 video to the desired rate. Simulation results demonstrate that our architecture achieves good perceptual picture quality under low bit-rate and varying network conditions while e ciently utilizing network resources.
