End-to-End Application Control of Video Streaming: Implementation and Performance Evaluation

This paper presents a solution for multimedia streaming adaptation to the conditions of the network. Since video content contains intrinsically redundant information, different degrees of compression can be applied. At the same time, if several errors and losses affect the communication, the transmission can be protected by correcting codes. The FP7 ICT OPTIMIX project aims at optimising the transmission of a video stream to a single user or to a group of clients, connected to the internet with a portable wireless device. In this context, a controlling process, coupling video compression to Forward Error Correction and exploiting feedback information coming from the clients, has been proposed. This paper presents the system architecture proposed for the use of this controller and evaluates the performance of the proposed scheme for both point to point and point to multi-point transmissions.
