For example, video data may be distributed in different buffers during playback under a content delivery network (Content Delivery Network, CDN) as shown in fig. 1. In some cases, the end portion of the video is not played, and in addition, in the case where the video is not completely played out in advance, data that has been buffered but not played is wasted, resulting in a large waste of bandwidth.
