Problems solved by technology

Since the total bandwidth of the CDN server is limited, the CDN server is usually running close to full capacity when a large number of users watch videos. However, because users cannot know the working status of the CDN server on the client side, a large number of newly joined users still choose high-definition If the video is too high, the bandwidth of the CDN server will be insufficient, which will cause frequent video playback on the client side and affect the user's video playback experience.

Description

technical field [0001] The invention relates to the field of video technology, in particular to a method and device for recommending video definition. Background technique [0002] Existing video network playback, for the same video content, the content distribution network (CDN) server can provide the client with multiple definitions of video corresponding to the video content, for example: for TV series A (A is the name of the TV series), CDN The server can provide standard-definition video, high-definition video or ultra-high-definition video, and the videos corresponding to each definition are independent of each other, and each has a different playback source address; users can choose the video with the definition they want to play on the client. There are big differences in the bit rate of different levels of definition. For example, the bit rate of high-definition video is 1 Mbps, and the bit rate of ultra-high-definition video is 1.5 Mbps. Playing a video with higher...
