Abstract

The invention relates to the technical field of real-time video, and provides a bit rate adaptive adjustment system applied to a cloud fusion platform, which is characterized by comprising: a media production unit, a media distribution unit, a media transcoding unit and a media consumption unit; the media The distribution unit is electrically connected to the media production unit, the media transcoding unit and the media consumption unit. The media distribution unit of the present invention can automatically adjust the transmission bandwidth according to the result of the bandwidth detection, the whole process is extremely fast, the cycle is extremely short, and the link can be quickly restored to the state of normal transmission; the media transcoding unit only converts one video source to one channel at most. The code stream of video multi-description encoding consumes less computing resources and network resources in the system, thereby reducing hardware costs; video multi-description encoding itself has a certain ability to resist packet loss, and the media consumption unit only needs to receive a sub-description to rebuild. The entire video frame can greatly improve the smoothness of video playback.

Description

technical field

[0001] The present invention relates to the technical field of real-time video, in particular to a system and method for self-adapting code rate adjustment applied to a cloud fusion platform. Background technique

[0002] There are many reasons for video packet loss during network transmission, such as software and hardware failures such as network switches, routers, and transmission cables; performance limitations of network switches, routers, and firewalls; network congestion caused by bandwidth limitations. Software and hardware failures usually mean that the available bandwidth is sufficient, which can be solved by using packet loss and retransmission technology. Device performance limitations and network congestion mean that the available bandwidth is insufficient. If the packet loss and retransmission technology is used, network congestion will be aggravated. The more effective solution is to reduce the sending bit rate. Although it will affect the disp...
