Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a live broadcast method for streaming media, a terminal device, a live broadcast system, and a computer-readable storage medium.
Background
Live broadcast can quickly and accurately transmit live information, and more people can watch live broadcast through websites or mobile phones due to strong telepresence. Real-time streaming media data is typically actively pushed to various viewer clients by a live server in a push-streaming manner.
"push streaming" is the process of actively pushing streaming media data to a viewer client in a network for viewing by the viewer client. The 'push stream' has higher requirement on the network, if the network is unstable, the live broadcast effect is poor, and the phenomena of blocking and the like occur when the audience watches the live broadcast. Moreover, for some popular streaming media data, the number of watching audience clients may reach tens of thousands, and the server is very stressed in "push streaming".
Peer-to-Peer (P2P) is a distributed network where participants in the P2P network share a portion of their own hardware resources that need to be served and content by the network and can be accessed directly by other Peer nodes (peers) without going through intermediate entities. Participants in this network are both resource (service and content) providers (server servers) and resource acquirers (client). Based on the characteristics of the P2P, the peer nodes in the P2P network can acquire the data of the resources very fast.
However, the conventional P2P technology is generated based on the file sharing requirement, and the P2P mode is often used in the scene of sharing video or audio material (e.g. downloading video resource of website such as video on demand). When streaming media data at each network node, resources are usually stored in each network node in the form of a file, and the file is split into a plurality of sub-files and transmitted to an opposite end node. Because the conventional P2P technology generally transmits data in a file-based manner, the file needs to be prepared in advance, and the file transmission manner makes the application scenarios of the P2P technology limited, which is not easy to achieve low latency and cannot adapt to the transmission of real-time video streams in a live broadcast mode with high real-time requirements.
