Development And Realization Of Multimedia Monitor System

With the rapid development of computer network and communication technology and multimedia technology, traditional monitor systems have greatly developed towards a new developing direction these years. Multimedia Video Central Control System (MVCCS) then appears, which a combination of corresponding technologies mentioned above is. Our task is to design such a system with full functions.MVCCS is a new monitor platform based on the multimedia technology, and it also brings more digitalization, network and multimedia technology and intelligent management to the monitor system. It fully incarnates the combination of the new information technology and monitor technology. Compared with the traditional monitor systems, MVMS based on PC and computer network greatly improves the quality of the images and the efficiency of the system, it also can reliably transfer the data through the Internet.This thesis expatiate the relative theories of MVCCS such as motion video capture, data code based on the technology of multimedia. Then the hardware and software models of MVCCS are presented. It analyses the function of each software module, and expressly introduces designing and implement of three important technologies: switch matrices, video transport, and infrared remote control.This article expounds the modularization designed thought about multimedia control system and the principle of the distributed control, and elucidates exactly the control principle of the controlling module, the switch between audio and video module, and the infrared remote control module. The writer also suggest show does achieve the fundamental means of the distributed control that base on the multiple single-chip digital communication technique and the digital communication technique between single-chip and PC. The infrared remote control module in this system has the function of "self study", and it can learn most of the coding of the infrared remote controllers and able to save them in this system. So this system can remote control most of multimedia equipment instead of change them circuitry.As a consequence, there are pictures of hardware design, PCB chat in the appendix of the paper.In the end, the high-speed data acquisition module is very good in function and application. It makes develop project more rapid and makes modify hardware circuit more easy. So combined with use of software, the module is applied for multimedia control device or other front-end equipment in video monitor.
