A Novel VideoTransmission Evaluation Framework Based on TCP-Friendly Congestion Control Mechanism
TFRC protocol is suitable for video transmission in a wire network, and quality assessment is also essential in a video transmission system. In this paper, a real-time video transmission system based on TFRC protocol is proposed, and the evaluation model about the system is improved in the framework of Evalvid. It assesses the quality and efficiency of the video transmission according to the actual video file, and analyzes losses frame in different video types during transmission as well as the video quality in receiver. The results of simulation experiment in NS-2 show that when real-time video transmitted in wire network environment using this system, the receiver can get satisfactory video quality by reason of the TFRC protocol friendliness and the smoothness of sending rate.
