Abstract
To design and realize a large scale video frequency switching network, which is rearrangeable and nonblocking, taking the video crosspoint switch as the basic switching unit, a three-stage nonblocking Clos network was constructed, and the signal route was selected by a route table. The multi-channel analog video signals can be transmitted simultaneously without blocking by rearranging the signal route. Comparing with the traditional single-stage video switching network, the number of crosspoints and switching units used in the three-stage network is reduced substantially and the whole switching system is simplified greatly; because signal line is not connected each other, the crosstalk between video signals is reduced and the transmitting performance of video switching network is improved distinctly.
