Generation method of video abstract fragments for digital video on demand

Abstract

The invention relates to a generation method of video abstract fragments for digital video on demand; a plurality of lenses in different time periods are randomly intercepted according to a set rule based on a complete video and sequentially spliced into the long video fragments about the contents of the whole video; that is to say, based on the lenses, the same camera is used to continuously shoot a section of video contents in the video; the contents of each lens form a whole, so as to respectively select the plurality of the lenses in the video from different time points, and sequentially splice the lenses, realize the organic link of the video abstract fragment contents, embody the overall contents of the video, and prevent the disorder of the contents. A user can preview the basic contents and the picture quality of the video by appreciating the video abstract fragments, determine if the user is interested in the video, so as to decide if to play the video on demand. The generation method of the video abstract fragments for digital video on demand can improve the time effect and the economy for the user to appreciate the video, so that a video content provider can also improve the audience rating, so as to improve the economic benefit and the social benefit and achieve win-win.

Description

technical field [0001] The invention relates to a method for generating video image information in a new format, more precisely, relates to a method for generating video summary fragments for digital video on demand, and belongs to the technical field of digital video image communication. Background technique [0002] Digital video on demand technology VOD (Video On Demand) is also called interactive TV on demand system. It is the product of the integrated development of computer technology, network technology and multimedia technology, and it is also a brand-new information service. This technology breaks away from the constraints of time and space that traditional television is bound to. Among them, cable TV video-on-demand is a typical application of digital video-on-demand technology on cable TV network. The business of broadcasting audio-visual programs selected and set by users themselves, including pay-per-view, carousel, on-demand real-time on-demand and other serv...

Problems solved by technology

However, the static abstract content provided by the existing video summarization technology is too simple, and the dynamic summarization fragments are mostly obtained by extracting highlights of the video or combining professional domain knowledge, and then performing semantic level analysis and other technical means to obtain, process The complexity of the process is high and the efficiency is low
