Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] This application provides a method for live video broadcasting, which can be applied to such as image 3 Shown in the live video system. Specifically, see image 3 , the live video system may include three parts: a content distribution network, a box (including an instance) and a client based on P2P technology.

[0026] Among them, the core of the content distribution network is to use intelligent strategy technology to push the content and services of the central server to the edge server, so that users can obtain services in places with relatively close geographical location and better service quality. Its key technologies include high-speed Caching, load balancing, content routing, content distribution, content storage and ...

Abstract

The invention discloses a video live broadcast method, device, equipment and system, and the method comprises the steps: determining a data source of target cache data which is a live broadcast sub-stream needing to be cached by a first client; when the data source is a second client, requesting target cache data from the second client, and directly performing data transmission between the secondclient and the first client; when the request for the target cache data from the second client fails, obtaining the target cache data through patch operation; and integrating the target cache data andthe historical cache data to enable the first client to perform video live broadcast, the historical cache data being live broadcast sub-stream cached by the first client. According to the technicalscheme provided by the invention, the bandwidth pressure of the content distribution network can be dispersed.

Description

technical field [0001] The present invention relates to the technical field of the Internet, in particular to a method, device, equipment and system for live video broadcasting. Background technique [0002] With the development of Internet technology, more and more videos are distributed on the Internet, and there is a tendency to replace traditional live TV. In particular, the live video uploaded by the host client, within a relatively small time difference, enables the viewer client to watch the live video, which is more and more favored by users. [0003] The current live video broadcasting system mainly adopts the combination of P2P (Point to point, peer-to-peer) technology and CDN (Content Delivery Network, content distribution network) technology. The framework formed by the combination of P2P technology and CDN technology is as follows: figure 1 shown. Divide the live video stream into figure 2 Multiple live substreams shown. [0004] Ideally, a client only dow...
