  • Apparatus having improved switching functions for processing video signals
    Patent number: 5041910
    Abstract: An apparatus for processing video signals which is adapted to a function for superimposing a video signal different from a video signal which is separated into a luminance signal and chromatic signal on the video signal is disclosed. The video signal processing circuit includes a first input terminal for inputting the video signal which is separated into the luminance signal and chromatic signal, a second input terminal to which the video signal is inputted as a composite signal, and a third input terminal to which an image signal different from the video signal is inputted, and a control circuit for switching the input signal from the third input terminal so as to superimpose the input signal from the third input terminal on the input signal from the second input terminal.
