Study Of Multi-video Multi-window Synthesis Display Technology

Nowadays,with the rapid development of information technology,people need to receive and deal with increasingly more and more complex information. Video information, as one of the most important part, plays a particularly important role. It becomes an important research topic that how to make people access to critical information from video sources rapidly, accurately and conveniently. This paper studied multi-video multi-window synthesis display technology as a solution to solve this problem.This paper described various standards of video signal and related technologies to video processing. Because that the real-time video signal has a tremendous volume of data, so it is necessary to study image scaling algorithm that have a good scaling property with low calculate consumption to use in the multi-window display scalable video windows. Then it proposed the expectation to reach by studying multi-video multi-window display technology. Fatherly it is simulated and demonstrated of the various display modes by programming in MATLAB. Chapter 4, as the focus of this paper, designed multi-video multi-window display system using ADSP-TS101S as the core. It is described that the scheme and key technologies of this system. It designed multi-video multi-window display algorithm and programmed software using Visual DSP++ IDE. The paper also considered video synthesis display technologie on the basis of multi-video multi-window display system in order to improve the video display system in the future. It contains video overlap technology, characters overlap technology and image mosaic technology.In this paper, the multi-video multi-window display system and software made initial success in debugging. It proved the feasibility of the topics, and the progress is satisfied.
