A Methods Of Multimedia Real Time Information Transmission Of Network Based On Mirror Display Driver

With the booming development of computer networks and information technology,it brings the network teaching model into a wide range of applications in the field of teaching. Network teaching depends on the implementation of network technology,multimedia technology and interactive information such as effective use of key technologies.Thus,the solution to multimedia messaging technology becomes a research focus on the network applications.The key to improve the efficiency is access to video information in multimedia information.This article explores the key technologies—high-pergormance,real-time multimedia information transmission algorithm about the modern long-distance teaching system,and further propose a method about accessing to screen information based on mirror display driver.First of all,the article equipps with the system design,carrys out the functional analysis on the five core modules such as screen crawling,nodule,data compressing module,data broadcasting module,terminal controling module,electronic handing module, then constructs a design framework of multimedia teaching systern based on the mirror display driver.Sencond,the article use "the grabgraf technology of mirror display driver" as the core technology,with "the technology of data compressing","the technology of multicast","the technology of data receivering","the technology of end-drawing",etc.,and detailed analyses main major functional modules,put forward a corresponding solutions,so provides a news idea for the specific implementation of multimedia network teaching system.Third,the article analyses and designs these programs of modules,lists some core code and makes a detailed explanation,eventually,it provides a set of high efficiency,low cost, high quality solutions.At the end.the article summarizes the work done by the subjects as well as the vision for the future.This article analyses the application of mirror display driver on multi-display environment environment to the interception and transmission of the screen innovativly. achieves captureing information efficiently on screen.To a certain extent,this study broadens the research ideas in transmission technology of screen information,and have practical value to build a perfect high-performance platform for distance learning, information transmission and other related fields.
