Abstract

Scalable video streaming over wireless link is a very challenging task due to the time-varying characteristics of wireless channel and limited battery resource in handheld devices. This paper first describes a general approach for joint source channel coding (JSCC) with optimal power consumption. Then, an end-to-end power-optimized architecture for video streaming is presented. Therein the channel-adaptive hybrid UEP (unequal error protection) and ARQ (automatic repeat request) scheme is proposed to achieve the minimal power consumption. Simulation results demonstrate the effectiveness of our proposed scheme
