Abstract
According to the characteristics of AVS video data, a RTP encapsulation method based on frame type is proposed. When the video data is encapsulated by the RTP protocol, different types of video data such as sequence header, sequence end, I frame, P frame and B frame are encapsulated with different method. Under the limit of maximum transmission unit (MTU), sequence headers, sequence ends and I frames are encapsulated individually to reduce the packet length and protect the important data. While multiple P frames and B frames are encapsulated into one RTP packet to reduce the quantity of the RTP packets and decrease the overload of link. Simulation results show that, compared to the frame-based encapsulation method, the proposed method can reduce the packet loss rate of the video data effectively and improve the quality of video service.
