Problems solved by technology

If only a small number of users order the video recording, a small number of VOD nodes can meet the demand of these users, and the method of storing the video recording in multiple VOD nodes in advance wastes a large amount of storage space of the VOD node

Embodiment Construction

[0050] Aiming at the problems existing in the prior art, the embodiment of the present invention proposes a video recording on-demand method, which can be applied in a VOD system, and the VOD system includes a VOD server and a plurality of VOD nodes. The VOD nodes are used to store video recordings and play the video recordings to users, and the VOD server is used to manage and control all VOD nodes, and this method can be applied to the VOD server.

[0051] The video recording referred to in the embodiment of the present invention may be a continuous video recording monitored by a camera, and the user may order the video recording, that is, the user plays back the video recording on his own display device.

[0052] Based on the method proposed in the embodiment of the present invention, part of the sub-videos in the continuous video recording can be stored in multiple VOD nodes in advance, and these multiple VOD nodes jointly undertake the on-demand requirements of the sub-vid...

Abstract

The present invention provides a video on demand method and device. The method comprises: dividing a video into a plurality of sub video segments, and calculating a warm-up value of each sub video segment; calculating an expected copying path number of each sub video segment according to the warm-up value of the sub video segment; when the current actual copying path number of each sub video segment is less than the expected copying path number of the sub video segment, increasing the copying path number of the sub video segment to reach the expected copying path number; when the current actual copying path number of each sub video segment is greater than the expected copying path number of the sub video segment, reducing the copying path number of the sub video segment to reach the expected copying path number, wherein each copying path of the sub video segment corresponds to one video on demand (VOD) node for storing the sub video segment. Through the adoption of the technical solution of the present invention, the occupied storage space of the VOD nodes can be reduced.

Description

technical field [0001] The invention relates to the field of video technology, in particular to a video recording on-demand method and device. Background technique [0002] The VOD (Video On Demand, video on demand) system is also called an interactive TV on demand system. It is an interactive video system that can order video recordings according to user needs, and can provide users with various interactive information services. Among them, the VOD system is the product of the development of computer technology, network technology, and multimedia technology. It gets rid of the constraints of time and space constraints of traditional TV. It can play the video recordings that users want to watch based on user needs. . [0003] The VOD system includes a large number of VOD nodes, and each VOD node can support limited video-on-demand requirements. For example, a VOD node can only play video recordings to 100 users at the same time. When a video recording has a large demand fo...
