Multimedia Teaching Playback Control System Research And Design

Along with the fly of the multi-media technique and networks, and more and more attentions our nation puts on education, teach information-based have already become main direction of the modern education development. To meet the demand of the modern teaching, the multimedia teaching system is getting extensive application for its making use of all sorts of resources and its convenient and vivid teaching method.The multi-media teaching system bases on the original one-way television networks foundation, and makes use of the modern multi-media technique and communication technique, as well as the technique of delivering pictures. The system adds two-way communication to the original system, so the two terminals can hand over at the same time with each other. Moreover, it makes various multi-media teaching equipments centralized management, concentration usage, the soft and hard ware share, thus saves resources. In addition, the multi-media teaching system also can connect with campus computer net, the long-range education net and international Internet, enjoying abundant campus net and internet resources.As the education modernization to the multimedia equipment demand increases unceasingly, This topic mainly completes the design of a bidirectional multimedia teaching control system, the system is centralized management and disperser used. A number of program source equipment and terminal equipment are connected together by this control system. Besides, it can be long-distance controlled in order to assistant teaching.In the whole multimedia teaching system, the central control part should receive the signal and finish the command from the general-control computer, complete the two-way communication with numerous terminals and program source controllers. Therefore it can be looked as a transportation vital point with alternant information for the whole system, thus it is a very important part, deciding the performance of the system; The terminal controller is designed to receive command from users at the terminal; The program source controller is designed to receive command from the center controller; besides, one software with friendly graphic user interface on the PC platform is designed to control the whole system. The article mainly launches to soft and hard ware design of the whole multimedia control system made up of the four parts mentioned above.
