Problems solved by technology

[0005] In order to solve the above problems, at present, when performing wireless video real-time transmission, the method of reducing the encoding rate or frame rate of the video is usually adopted, or the method of extracting I frames is used to realize the transmission of the real-time video. However, reducing the bit rate will affect the video quality. playback clarity

Embodiment 1

[0035] Such as figure 2 Shown, a kind of self-adaptive transmission system of 3G wireless network remote video monitoring, described system comprises video encoding sending unit, 3G network, server receiving terminal and receiving terminal, wherein:

[0036] The function of the video encoding sending unit is to perform H.264 compression encoding on the collected original video images, and transmit the video data to the receiving end of the server through the 3G network through the sending end through the transmission mechanism described in any one of the above claims;

[0037] The server will detect the network situation, receive the video data from the sender, and count the packet loss, retransmit the UDP packet or discard the entire non-I frame data;

[0038] After receiving the complete frame data, forward the data to the receiving terminal requesting the video;

[0039] The receiving terminal receives the forwarded video from the server, decodes and plays it.

Abstract

The invention discloses a third-generation (3G) network based video monitoring system bandwidth self-adaption transmission method applicable to a sending end and a receiving end connected through a 3G network. The 3G network based video monitoring system bandwidth self-adaption transmission method includes steps that the sending end performs compressed encoding on a real-time video to be sent, sends a video user datagram protocol (UDP) data packet through a private protocol, dynamically adjusting a sending rate according to a feedback message sent by the receiving end, and performs accumulative confirmation and retransmission on video data lost by the receiving end; the receiving end receives the video UDP data package, counts packet loss conditions, requests the sending end to perform retransmission and provides the sending end with network conditions. By means of the technology, when a bandwidth of a transmission network is low or poor in stability, the 3G network based video monitoring system bandwidth self-adaption transmission method is capable of guaranteeing high-efficiency sending of data frames to a monitoring end and guaranteeing monitoring effects without influencing real-time and complete transmission of video images.

Description

technical field [0001] The invention relates to the field of 3G video monitoring, and is a method for transmitting real-time streaming media through a 3G network, in particular to a bandwidth adaptive transmission method for a video monitoring system based on the 3G network. Background technique [0002] With the continuous improvement of people's requirements for the safety of living and working environments, the importance of safety protection systems is becoming more and more prominent. Among them, the video monitoring system has attracted more and more attention because of its intuition, convenience and rich information content, making it an important part of the security system. In recent years, with the rapid development of computer, network, image processing and transmission technology, video surveillance technology has also developed rapidly. [0003] The 3G network wireless transmission system is a brand-new network technology, which can provide video images and so...
