Generally, Multiple video source is used in a television station. In exactly, The same way these video signals require multiple destination equipment for visualization or processing. The video router that is used to route any source video signal equipment to any destination equipment as needed.
Types of the video router depends on the video signal. For example, the video signal may be analog or digital. So, we can understand that the type of video router is determined based on the type of signal of the station.
Generally, the video router does not process or change the video signal, only transmit from any source to any destination. Although the video router does not change the signal, but re-amplify. So that the signal does not lose the gain. 32 x 32, 64 x 64, 128 x 128, 256 x 256 are written for this to reveal the video router’s input and output numbers. The first number indicates input and the last numbers mention of the output capacity. In present, the video router is auto sensible. That is, one or all of the SD-SDI, HD-SDI, 3G-SDI has the opportunity of routing. But router don’t conversion any signal. For example, an input HD-SDI signal will not be able to output SD-SDI format. In addition, some video router has multivariate options.
The router control panel (RCP) is used for routing. The number of control panels shall more than one. In that case, the router admin permits what source-destination under any RCP? The router is usually integrated into the Station Automation application so that automation can do the source selection according to its needs. IP addresses, dip-switches, Q-Links are used to give different RCP addresses to each other’s.
