摘要：

In cellular environments, video broadcasting is a challenging problem in which the number of users receiving the service and the average successfully decoded video data-rate have to be intelligently optimized. When video is broadcasted using the 3G packet data standard, 1xEV-DO, the code space may be divided among the multiple layers if scalable video coding is employed. In this paper, we propose a novel, multi-objective optimized video broadcasting scheme for 1xEV-DO and investigate the feasibility of using multiple layers for transmission. The multi-objective optimization aims to find the best compromise between maximizing the average decodable video data-rate and minimizing the basic quality video outage probability. Simulations conducted for, the ITU Pedestrian A and Vehicular B channels show that high data-rates with low outages are possible when 1xEV-DO is used for video broadcasting, however, it may not be desirable to use scalable video coding for this purpose.
