Embodiment Construction

[0079] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0080] A video transmission method provided by this application can be applied to such as figure 1 In the video transmission system shown, the system includes a client, an edge server, and a source server; in this system, all video resources are stored on the source server, and hot content is stored in the edge server. Among them, when the client is watching the video, it will initiate a video request to the source server. The source server and the edge server cooperate with each other. After receiving the client request, the source server will redirect the request to the ...

Abstract

The present application relates to a video transmission method, system, computer equipment and storage medium, using an edge server to prefetch and cache highly popular videos in advance, so that when a client requests a video, the edge server can efficiently send the corresponding The video is output to the client, which greatly improves the performance and efficiency of video transmission.

Description

technical field [0001] The present application relates to the technical field of computer networks, in particular to a video transmission method, system, computer equipment and storage medium. Background technique [0002] Dynamic Adaptive Streaming over HTTP (DASH) technology (Dynamic Adaptive Streaming over HTTP, DASH) based on HyperText Transfer Protocol (HyperText Transfer Protocol, HTTP) has been widely used because of its flexibility and compressibility. Bandwidth utilization, thereby improving user experience. [0003] Usually in the DASH transmission mode, the client requests the content based on the video block sequence and adopts the bit rate adaptive algorithm locally, adaptively selects the most appropriate bit rate according to the real-time network status, and automatically adjusts the download and playback scheme according to the current network conditions, so as to Avoid playback freeze or re-buffering events, thereby improving the overall transmission effic...
