A video transmission method based on QoS in space tracking networks

This article proposes a method of video transmission by partition based on network differentiated service. The method firstly divides videos spatially and temporally into partitions according to a significant area deciding algorithm, and then establishes QoS indexes and set the service type for different video partitions according to network available bandwidths and MPEG-4 frame types. Using different queue management mechanisms for different types of services, this article achieves the purpose of differentiating services. The experimental results show that the proposed method can ensure the transmission quality of the concerned video area compared to common methods.
