Problems solved by technology

This solution needs to count the packet loss rate of each receiving point, and then comprehensively adjust the bandwidth of data transmission. However, when the number of receiving points is relatively large, the network conditions of each receiving point may vary greatly. Poor, if you adjust the transmission bandwidth according to a certain value, it will cause the place with good bandwidth to receive high-quality video, but the quality of the video received after adjustment will be reduced, and the place with po

Embodiment Construction

[0018] The present invention utilizes the real-time nature of the UDP transmission protocol to firstly ensure the real-time arrival of video transmission, and in addition, a corresponding packet loss compensation mechanism is added in the communication process, which greatly improves the reliability of transmission. The industry calls this technology RUDP ( Reliable UDP transport protocol). At present, this technology has been successfully applied to the self-developed NetDong multimedia video conferencing system, LiveUC cloud conference system, NetDong remote video monitoring system and other products, and achieved very good results; after using this technology, it is comparable to other products on the market. Compared with similar products, the market competitiveness has been greatly improved.

[0019] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0020] as attached figure 1 A schematic dia...

Abstract

The invention discloses an RUDP-based real-time video transmission method under internet condition. By adopting a client/server (C/S) structure model, the technical scheme comprises specific steps of video data distribution, packet loss detection, report receiving, packet loss recovery, receiving end data sorting, decoding and display and the like. According to the RUDP-based real-time video transmission method under internet condition, problems that video receiving is delayed and paused, mosaic appears on the picture, the screen is blurred and the like due to network congestion, data packet loss and the like can be solved under the internet condition. The RUDP-based real-time video transmission method under the internet condition has the main advantages that existing network conditions of the user can be improved without extra spending and the user can make use of the existing network condition to obtain clearer and smoother video communication effects.

Description

technical field [0001] The invention relates to the field of video transmission, in particular to an RUDP-based real-time video transmission method. Background technique [0002] At present, the development direction of video communication has the characteristics of popularization, multi-terminal, multi-network, and high-definition. This puts forward higher requirements for the network carrier of video communication, that is, higher and more stable network bandwidth guarantee and efficient interconnection of various networks (such as enterprise private network, ADSL, 3G network, etc.). Although the current Internet bandwidth has been greatly improved, there is still poor interoperability between different operators, and it is difficult for the same operator to have stable bandwidth guarantee due to different regions. Therefore, how to obtain clear, smooth and real-time video communication quality under unstable Internet bandwidth conditions is a considerable technical probl...
