The Design of a New Multimedia Voice Synchronization Responder

To resolve the problems of the responder of the day such as unfair responding and inconvenient operation, the project provides a new kind of multimedia voice synchronization responder which designed by applying VC＋ ＋. The main composition of the responder hardware includes the responder, the responding button for competitors, the responding button for hosts PC equipment, projector, screen, multi-media audio, etc. And the software is composed of MCU program and PC program design. The practical results show that the system structure is reasonable and the hardware and software with high flexibility is feasible, which can put the fair responding competition and convenient operation into effect. What＇s more, it applies to various sorts of responding activities.
