Problems solved by technology

[0002] Webrtc currently uses a point-to-point video transmission solution. In a pair of N video live broadcast scenarios, the video sender needs to copy the stream and send it to multiple video receivers. N is relatively large, which will inevitably lead to performance pressure on the video sender.

Abstract

The invention discloses a multicast-based webrtc video stream transmission system, comprising a source-end video acquisition module, a source-end webrtc signaling module, a source-end DTLS module, a source-end SRTP module, a source-end multicast sending module, and a central webrtc Signaling control module, multicast network switch, display-side multicast reception, display-side webrtc signaling module, display-side DTLS module, display-side SRTP module, display-side video display module, source-side virtual channel module, display-side virtual channel module ; The source video acquisition module is a one-to-many video source, collects video data in real time, performs video compression coding, and sends it to the source SRTP module. The present invention uses multicast to transmit webrtc video streams, realizes a one-to-N video live broadcast scene, reduces the distribution pressure of the video source end and the network data transmission volume, and at the same time, the webrtc stream encryption feature improves the security of the video multicast application, and reduces the packet loss of webrtc. Retransmission provides multicast reliability.

Description

technical field [0001] The invention relates to the field of network transmission, in particular to a multicast-based webrtc video stream transmission system. Background technique [0002] Webrtc currently uses a point-to-point video transmission scheme. In a one-to-N video live broadcast scenario, the video sender needs to copy the stream and send it to multiple video receivers. The N is relatively large, which will inevitably lead to performance pressure on the video sender. Network multicast uses the switching network itself to realize the calculation of stream distribution. If webrtc uses multicast to optimize one-to-N video live broadcast scenarios, it can increase the number of N and optimize the network load. SUMMARY OF THE INVENTION [0003] In order to solve the above technical problems and optimize the network load of video streaming transmission, the present invention provides the following technical solutions: [0004] A multicast-based webrtc video streaming ...
