Abstract

The embodiment of the invention provides a video-data-on-demand method and device and a video-on-demand node. The method is applied to a video-on-demand node in a video-on-demand system, the video-on-demand system further comprises a video management node, and the video management node is used for receiving a video-on-demand request sent by a client and distributing the video-on-demand request tothe video-on-demand node. The method comprises the following steps: reading hotspot video data from a video source and storing the hotspot video data locally in a video-on-demand node, wherein the hotspot video data is video data of which the on-demand number is greater than a preset hotspot threshold; determining whether the target video data belongs to hotspot video data or not, wherein the target video data is video data to which the video-on-demand request aims; if the target video data belongs to the hotspot video data, reading the target video data from the locally stored hotspot video data; and sending the target video data to a client. The possibility that normal video playback cannot be achieved due to the fact that the load of a video source is too high can be reduced (even eliminated).

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a video data on-demand method, device and video on-demand node. Background technique [0002] In some application scenarios, the user may need to play back a specific video in the video source. In related technologies, the client may send a video-on-demand request for the specific video. After receiving the video-on-demand request, the video-on-demand node queries the stored The video source of the specific video, access the video source to obtain the specific video, and return the obtained specific video to the client. [0003] However, the load capacity of the video source is limited. If it is accessed frequently within a certain period of time, the video may not be played back normally due to the high load of the video source. Contents of the invention [0004] The purpose of the embodiments of the present invention is to provide a video data on-demand method, so a...
