Abstract: Advances in wireless access technologies like WiMax and LTE are driving the wireless video applications and wireless broadcasting video service in particular. Though existing erasure codes are designed to achieve high throughput for wireless broadcast/multicast, their potential for wireless video broadcasting can only be achieved if the distortions associated with video packets and their complex decoding dependency are also considered. In this paper, we propose a Joint Video Adaptation and Erasure Code(JVEC) for wireless video broadcast, taking into consideration the video decoding dependency among temporal scalable decoding dependency among I, P and B frames, and formulate a solution to minimize the average video distortion. Assuming that the source knows the erasure state of transmitted packets at the receiver side through the feedback channel, JVEC can generate erasure codes on the fly to firstly guarantee the decoding of important frames and secondly correct erased frames as many as possible. The simulation result shows that JVEC can achieve less video distortion compared with other erasure codes, such as LT code, RT oblivious code and SLT code.
