Video broadcast over the WWAN remains difficult due to the unavailable packet losses. Previous cooperative solutions for multi-homed devices listening to the same video broadcast call for local recovery via packet sharing. It is known that using structured network coding (SNC) to encode received packets before peer exchange can further improve repair performance, the decision of who should send repair packets in what SNC types at available transmission opportunities were not optimized in any formal way. In this paper, we propose a distributed decision making strategy based on Markov decision process (MDP). Experiments show that decisions made using our proposed MDP outperformed decisions made by a random scheme by at least 5dB in PSNR in received video quality.
