Abstract

The embodiment of the invention provides a method and device of downloading and providing video files. The device comprises a client side monitoring a current network speed; sending a notification to a media server, wherein the notification carrying current network speed information; and downloading video fragments provided by the media server, wherein a video fragment comprises a plurality of video fragments; receiving a notification at the media server end; determining the mapping relation between the current network speed determined according to the current network speed information and the definition levels of the video fragments, determining the video fragments of corresponding definition levels for downloading by clients, wherein a video fragment comprises a plurality of the video fragments, and at the media server end, video fragments having same contents at least store two kinds of video fragments of different definition levels; and providing video fragments of corresponding definition levels for the clients. The method and device can realize video file definition automatic switching.

Description

technical field [0001] The embodiment of the present invention relates to the field of video technology, and in particular to a method and device for downloading and providing video files. Background technique [0002] The playback of network video (including on-demand and live broadcast) is a very important and core function of mobile terminals and TVs. Because the speed of the network is not very uniform, some access speeds are fast, while others are slow. Moreover, the speed of the network is not very stable. For some access users who share bandwidth, the network speed drops significantly when there are many access users. In order to provide users with the best experience, video websites usually prepare sources of multiple resolutions for each video content at the same time, and provide a list for users to choose from. SD, HD, UHD, 1080P, 4K, etc. [0003] The existing solution is to select high-definition video files for playback by default, and the default definition...
