Abstract

Scalable video delivery over wireless link is a very challenging task due to the time-varying characteristics of wireless channels. This paper proposes a channel-adaptive error control scheme for efficiently video delivery, which consists of dynamically channel estimation and channel- adaptive Unequal Error Protection (UEP). In our proposed channel-adaptive UEP scheme, a bit allocation algorithm is presented to periodically allocate the available bits among different video layers based on varying channel conditions so as to minimize the end-to-end distortion. Simulation results show that our proposed scheme is efficient under various channel conditions.
