| 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 Numeric Video Monitor System (MNVMS) then appears, which is a combination of corresponding technology mentioned above. Our task is to design such a system with full functions.MNVMS 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, MNVMS 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 expatiates the relative theories of MNVMS such as motion video capture, data code and real-time transport protocol based on the technology of multimedia and computer network. Then the hardware and software models of MNVMS are presented. It analyses the function of each software module, and expressly introduces designing and implement of three important technology: cycled data storage, alarm recording , network monitor.By debugging the system, the developing team's production - "MS301" MNVMS has good functions and good stability. At present, "MS301" MNVMS has been applied at hundreds of bank and win client's praising. This project has passed detailed appraisal of Science Office Of SiChuan Province, and was estimated that it has reach top level. At present. This project is applying for second award of Science Advancement of SiChuan Province. |
