The Development Of The Multimedia Controller

Along with the rapid development of computer application technology, network and multi- media technology, all or different levels school design various teaching activities by providing late-model teaching environments and using advanced methods of teaching. It leads to grow more and more classroom by multi- media teaching equipment, such as computer and projector and so on. When we build multi- media classroom. Multimedia concentrated controller is one of indispensable important equipment. Multimedia concentrated controller is the most up-to-date science and technology connecting with electronic technology, computer technology and net technology. It can control all of the equipments. The typical characteristic-is that operatonal process become of simpleness, and user can esay it.This paper is devoted to exploitation and manufacture of Multimedia concentrated controller. The system has some characteristic such as powerful function, fine performance, good compatibleness , convenient assemblage and easy operation etc. Multimedia concentrated controller can control various equipments, switch audio-vedio signals and VGA signals, and control lights, motor-driven curtain and air conditioner etc. Multimedia concentrated controller can be used in the auditorium, meeting room and multifunctional hall. Particular contents include collecting infrared code > alternating multi-channel sound video signal, turning on or turning off some function and managing electric source.This paper presents tentative idea that acquire communication engineering use DTMF Double sound multi- frequencies signal between computer and Multimedia concentrated controller. This plan is a great success, and whole functions of Multimedia concentrated controller come true. Themain research topics of this paper include module of collecting and saving infrared code, module of controlling apparatus and equipment, module of alternating multi-channel sound video signal and module of managing electric source.
