Due to the rapid growth of the Internet TV users,so selecting the appropriate video congestion control is extremely important. On the basis of the analysis and comparison of TCP Friendly Rate Control(TFRC) and rate adaptation protocol(RAP),proposing a double fuzzy control strategy that the closed-loop gradient estimation methods,the ability to dynamically adaptive output encoded video streams instead of relying on packet loss rate. Simulation results show that this congestion estimation method compared with conventional congestion control,transmission rate of a smoother,higher bandwidth utilization,thereby greatly reducing the number dropout in the video receiving side,the video transmission quality has improved significantly.
