Abstract

The invention discloses a web-based real-time communication media multicast method and system. The WebRTC sender encrypts the media information to be transmitted to obtain an encrypted media stream, and sends the encrypted media stream to the media broadcasting device. In the media broadcasting device, the virtual receiving end decrypts the encrypted media stream to obtain media information, and sends the media information to the media distribution module, and the media distribution module forwards the media information to the associated virtual sending end. The negotiated encryption parameters encrypt the media information to obtain the corresponding distribution media stream, and send the distribution media stream to the corresponding WebRTC receiver. The WebRTC receiving end uses pre-negotiated encryption parameters to decrypt the distributed media stream to obtain media information, thereby realizing media multicast. The invention distributes the media stream generated by one WebRTC sending terminal to multiple WebRTC receiving terminals through the media broadcasting equipment, and realizes the multicasting function of the media stream while avoiding multiple encodings.

Description

technical field

[0001] The invention relates to the communication field, in particular to a media multicast method and system based on Web real-time communication. Background technique

[0002] Web Real-time Communication Technology (WebRTC) is a technical system designed to realize multimedia audio and video real-time communication through browser and Web technology. Existing specifications are mainly aimed at P2P communication application scenarios, and lack relevant technical specifications for multi-party communication such as multicast, broadcast, and conference. The existing WebRTC multicast (Multicast) solution requires the sender to establish a connection with each receiver, and perform independent audio and video encoding for each audio and video stream. The existing WebRTC multicast solution has the following problems: concurrent multi-channel encoding results in high computational complexity and high power consumption, and the number of multicast channels that ca...
