Embodiment Construction

[0028] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0029] In the video-on-demand system, more servers need to be deployed in the network to store video files and provide video file content push services for clients. At present, in order to reduce the storage pressure on the server, when a client requests to order a certain video fragment, the server will store the video fragment in the client that sent the on-demand request, so that when other clients subsequently order the video fragment Serving other clients. However, in practical applications, the storage space of most clients is still in an idle state, which causes a waste of resources and does not effectively reduce the pressure on the server.

[0030]In view of the above problems, the inventors of the present application propose the following embodiments to solve the above problems after rese...

Abstract

The invention provides a video fragment caching method and device and a video-on-demand system, and belongs to the technical field of video-on-demand. The video fragment caching method comprises the following steps: after a client successfully caches a target video fragment of a requested target video, judging whether the residual storage space of the client is greater than a preset value or not,wherein the preset value is a storage space value, configured by the server, of normal operation of the client; and if so, sending an instruction of caching other video fragments except the target video fragment in the target video meeting a preset caching condition to the client. In the embodiment of the invention, compared with the prior art, the video fragment caching method has the advantagesthat idle resources of the client can be fully and reasonably utilized, the pressure of the server is reduced, and the operation cost of the video-on-demand system is reduced.

Description

technical field [0001] The present application relates to the technical field of video-on-demand, and in particular, to a method and device for caching video fragments and a video-on-demand system. Background technique [0002] In the video-on-demand system, more servers need to be deployed in the network to store video files and provide video file content push services for clients. At present, in order to reduce the storage pressure on the server, when a client requests to order a certain video fragment, the server will store the video fragment in the client that sent the on-demand request, so that when other clients subsequently order the video fragment Serving other clients. However, in practical applications, the storage space of most clients is still in an idle state, which causes a waste of resources and does not effectively reduce the pressure on the server. Contents of the invention [0003] The purpose of the embodiments of the present application is to provide ...
