Abstract

The invention discloses a video living broadcast method and device, belonging to the on-line video technical field. The method and device obtain video data in a CDN (Content Delivery Network) and P2P composite mode, possess stronger network jittering resistance, and improve living broadcast stability. Besides, because of introduction of the P2P technology, the sources of video data are expanded, thereby diffusing server pressure in a CDN, helping reducing a server scale in the CDN, consequently reducing the cost of a network live video living broadcast system, and facilitating wide application of the network live video living broadcast system. The method and device are very suitable for low cost application scenes such as on-line education, sport living broadcast, news living broadcast, etc., have the advantages of low delay and high stability, and greatly improve the prior art.

Description

technical field [0001] The present invention relates to the technical field of online video, in particular to a video live broadcast method and device. Background technique [0002] With the development of Internet technology, more and more live videos are distributed on the Internet, which tends to replace traditional live TV. [0003] The current network live broadcast system mainly adopts the traditional single-link distribution mechanism, which has the advantage of small delay, but it is not conducive to resisting network jitter, so when there is an obstacle in the connection between the live broadcast terminal and the remote video server, it will Seriously affect the video playback of the live broadcast terminal, greatly reducing the viewing experience of network users. [0004] In addition, the commonly used video distribution mechanism is CDN (Content Delivery Network, content distribution network) technology. The core of CDN is to use intelligent strategy technology...
