Problems solved by technology

In the switching scenario, the requesting node generally has the same data stored locally as the quick start data, which will cause the video images corresponding to the quick start data to be played repeatedly, greatly affecting the playback effect of the live video

Embodiment Construction

[0022] 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.

[0023] An embodiment of the present invention provides a method for transmitting live video data, and the method can be applied to a CDN cluster-based live broadcast acceleration system. Such as figure 1 As shown, the live broadcast acceleration system may include a CDN cluster, an anchor terminal, and a viewer terminal. The CDN cluster may at least include an edge node, a static parent node, and a dynamic parent node, wherein the edge node may be the closest node of the CDN cluster to the user side, and each Each edge node can independently provide CDN services for users in an area, and can directly interact with the user end for data. For example, the streaming edge node can receive the live video stream pushed by the anchor end, and...

Abstract

The invention discloses a method for transmitting live broadcast video data and a live broadcast acceleration system, and belongs to the technical field of data transmission. The method comprises thesteps that a target node is switched to a target superior node for stream pulling, and a target video stream of a target live video sent by the target superior node is received; the target node reserves the frame data of the target video stream according to the new-old relationship between the target video stream and the video stream before switching and the DTS of the frame data in the target video stream; and the target node sends the reserved frame data of the target live video to a subordinate node of the target node. By adopting the method and the device, the problem of repeated playing of the video picture caused by repeated receiving of the data can be solved, so that the playing effect of the live video is improved.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a method for transmitting live video data and a live broadcast acceleration system. Background technique [0002] With the development of Internet technology and the continuous increase of broadband speed, the connection between the Internet and people's lives has become increasingly close, and watching live broadcasts has become a mainstream form of entertainment. In order to improve the quality of live broadcast services, operators of live broadcast platforms mostly provide live broadcast services based on CDN (Content Delivery Network, content distribution network) clusters. [0003] The host can push the live video stream to the nearest CDN edge node (which can be called the push edge node). After the streaming edge node receives the live video stream, it can select multiple dynamic parent nodes in the CDN cluster according to a preset algorithm, and then push the ...
