Abstract

The invention discloses a method for improving the RTP video streaming treatment efficiency in the low-speed network. A video collecting end is responsible for obtaining video data in real time, a video coding and packaging module compresses and encodes the video data at first to form videos of a standard format H.264, then RTP packaging is carried out on the compressed videos, and the packaged data are sent to a network cache region; a network sending end obtains the shared RTP package data in the network cache region to generate the RTP frame data, and a plurality of TCP socket pairs are uploaded to the network sending end through the foundation network; a network receiving end as a video server transmits the RTP data by setting up TCP sockets with the network sending end. According to the method, the sockets transmit real-time RTP streaming together, a plurality of small RTP packages are reasonably combined and transmitted at a time, the bandwidth utilization rate is increased, the network transmission efficiency is improved, and the problems of frame loss, frame hysteresis and screen blurring caused by real-time transmission of video streaming can be effectively solved.

Description

technical field [0001] The invention relates to a network transmission method, in particular to a method for improving the processing efficiency of RTP video streams in a low-speed network. Background technique [0002] With the popularization of 3G network and the advent of the LTE era, people hope to obtain multimedia information such as audio and video at any time. The RTP protocol is a network transmission protocol designed to support multimedia communication, so that streaming media players are widely used on various network terminals. [0003] RTP-encapsulated data packets are easy to transmit on the network, and its sequence number field and timestamp field ensure that the receiving end can realize packet loss detection and packet sequence recovery. In the RTP / RTSP protocol, both the RTP data packet and the RTCP data packet are transmitted using the UDP protocol, and the RTCP data packet is used for real-time monitoring of data transmission quality and congestion con...
