The Key Issues to the Switch of the Multi-Channel Video Signal

Abstract:

This paper proposes a multi-channel video signal switch system. The authors introduce a key technology which uses AD8108/AD8109 as switching devices, micro-controller LPC2214ARM as the control unit to form a multi-channel video switch. Firstly, this paper analyzes the working principle of AD8108/AD8109 and LPC2214. Then the authors give the hardware structure of the multi-channel video switch system, and the software design of the system. Finally, this paper puts forward the key issues to the switch of the multi-channel video signal after experiments. Facts have shown that these factors must be taken into account in the design of successful video signal switch systems.
