Video size switching system and video size switching method facing display terminal

Abstract

The invention provides a video size switching system and a video size switching method facing a display terminal. The method includes the steps: firstly, computing the size of interested windows according to interactive choices of users and by designing perception window models; then detecting long shots, fusing various factors of human eyes to view videos into each frame of image in each long shot by adopting a knowledge-based fuzzy reasoning decision-making system, automatically identifying interested areas and cutting the interested areas to serve as display content of the display terminal; and finally, performing time-domain smoothing for central points of all the interested areas identified in the long shots, so that consistency and continuity of time domains of the interested areas are guaranteed. Additionally, the video size switching system facing the display terminal is based on the method. From the perspective of video source format switching technology, the method with the technical scheme can be self-adaptive to switch a common video format into a target video format which can be played by a small-sized terminal.

Description

technical field [0001] The invention relates to the field of multimedia technology, in particular to a display terminal-oriented video size adaptive conversion system and method. Background technique [0002] With the development and maturity of the third-generation mobile wireless communication protocol, the bandwidth of the wireless communication network is increasing day by day, which can meet the bandwidth requirements of users' multimedia services. Therefore more and more users of mobile terminals (such as: handheld portable devices such as mobile phones, PDAs, Pocket PCs) like to watch various videos by mobile phones. This increasingly mature communication technology is more convenient for users to enjoy multimedia services anytime and anywhere, enriching people's entertainment life, and also reflects the characteristics of increasingly diversified multimedia services. People are no longer tied to home TVs or public theaters to enjoy the entertainment brought by vario...

Problems solved by technology

However, the problem with this is that some important information may be lost, affecting the viewing experience of the human eye

Therefore, if the visual perception window cuts part of the original video information, but as long as it can fully display the most concerned area of ​​the human eye in the video image within the limited window, which is more in line with the original intention of the original shooter, it will not give people a sense of the original video. The perception of video information has too much impact. Compared with the poor visual perception of smaller screens, it will increase the visual experience of the audience watching the game
