Abstract
A video switching circuit is capable of switching between a Y/C separated video signal and a composite video signal. The video switching circuit includes a first and a second video input terminals. The Y/C separated video signal is inputted to said first video input terminal and plural composite video signals are inputted to the second video input terminal when these two types of video signal inputs are required. The circuit is equipped with a first and a second selector. One of the plural composite video signals inputted to the second video input is selected by the first selector. The selected composite video signal is separated into luminance and chrominance signals by a Y/C separator. As a result, the output of the Y/C separator and the signal inputted by the first video input are similar. Thus, these two signals can be alternatively switched by the second selector according to the control signal given by an appropriate controller.
