Problems solved by technology
Conventional on-demand requests request data from edge nodes or edge nodes of CDN manufacturers through http / https get requests. During an http on-demand process, there is only one data source. When a network failure or playback exception occurs, only through It can only be solved by retrying or manually switching to other nodes, which affects the viewing experience and directly affects the user viscosity of the video platform

Embodiment Construction
[0031] Such as figure 1 As shown, the implementation steps of the method for downloading fragments based on the size of the playback cache in this embodiment include: downloading the video data required for playing the video based on the fragments, and regularly detecting the status of the playback cache when downloading the video data required for each current fragment. Playable duration, if the playable duration of the playback cache is less than the first threshold, select an available download source with a higher download rate as the download source for the next segment; if the playable duration of the playback cache is greater than the second threshold, select the bandwidth An available download source with a lower price is used as a download source for the next segment, and the second threshold is greater than the first threshold. Among them, the first threshold is the critical value of freeze. If it is lower than the first threshold, playback may freeze. The first thre...

The invention discloses a method and a system for downloading fragments based on playing cache sizes. According to the method, video data required for playing a video is downloaded on the basis of fragments, the playable duration of a playing cache is detected regularly when the video data required for downloading each current fragment is downloaded, and if the playable duration of the playing cache is smaller than a first threshold value, an available downloading source with a higher downloading rate is selected as a downloading source of a next fragment; And if the playable duration of the playing cache is greater than a second threshold value, selecting an available downloading source with a lower bandwidth price as a downloading source of the next fragment, and the second threshold value is greater than the first threshold value. According to the invention, errors can be effectively reduced, the playing jamming probability is reduced, and the bandwidth cost is reduced, so that thewatching experience of Internet video-on-demand is improved, and the user viscosity of a video platform is improved.
Description
technical field [0001] The invention relates to the Internet video-on-demand technology, in particular to a method and system for segmented downloading based on the playback cache size. Background technique [0002] Currently, Internet video-on-demand is basically an http-on-demand request, and the formats mainly include mp4 and hls. Conventional on-demand requests request data from edge nodes or edge nodes of CDN manufacturers through http / https get requests. During an http on-demand process, there is only one data source. When a network failure or playback exception occurs, only through It can only be solved by retrying or manually switching to other nodes, which affects the viewing experience and directly affects the user viscosity of the video platform. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method and system for segmented downloading based on playback cache size in view of the above problems in t...
