Abstract
In cellular environments, video broadcasting is a challenging problem in which the number of users receiving the service and the average video quality of the received stream have to be intelligently optimized. In this paper, we propose a novel, multi-objective optimized cross-layer video broadcasting scheme for a wireless system capable of supporting a multitude of transmission data-rates using the H.264/AVC. The multi-objective, cross-layer optimization aims to Find the H.264/AVC as well as the physical layer parameters jointly to reach the optimal compromise between maximizing the average received video PSNR and minimizing the video broadcast service outage probability. Simulations conducted for the ITU Pedestrian A and Vehicular B channels show that high data-rates with low outages are possible for video broadcasting when such a cross-layer design is used.
