Abstract :
In this paper we develop joint source rate selection, power management, and error control schemes for wireless multicast of SNR scalable video. In particular, two error control schemes are analyzed and compared-type 2 hybrid ARQ/FEC (T2HA/F) and non-causal error control (NCEC). T2HA/F is based on incremental redundancy chosen to recover losses and provide the required level of video quality for all users. On the other hand, NCEC relies on error concealment from future video data whose quality is adaptively adjusted to bring the video quality up to the desired level for all users. Experimental results indicate that NCEC can be significantly more efficient than T2HA/F
