Internet era in the context of increasing popularity of mobile terminals, network video browsing has become an indispensable feature of wireless terminals. However, in order to improve the reliability of video multicast, this paper increases the gain system from the overlapping access points in the coverage area, because of the low reliability of the inter-link interference between the wireless networks. Improve the fairness of the system, and propose and design a multi-point broadcast scheme based on network coding and multi-access point collaboration. The program will first divide each video segment into the same segment and divide the access point completely and not completely interfere with the two models. The video multicast problem when the transmission range between the access points is overlapped is modeled as Linear programming optimization problem, a two-stage heuristic algorithm is designed to solve the problem. By using multiple access points to get the gain of space and time diversity, the reliability of data transmission is improved, and data is transmitted in parallel by allowing access points that interfere with , To improve the system utility. Finally, the simulation experiment is used to verify the validity of the number of packets to be decoded, the total amount of packets received and the fairness.
