RUDP-based real-time video transmission method under internet condition

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...

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 poor bandwidth may still not receive smooth video. video

In addition, the jitter of the network is often instantaneous and intermittent, and the bandwidth statistics will have a certain time lag, so it is difficult to ensure that the adjusted bandwidth at the same time point is consistent with the actual network status of the user

This solution is more suitable for interactive video communication with a small number of participants, and it is difficult to adapt to large-scale video conferencing and other applications.
