Patent ID: 7242844

Claim:
A video signal recording and reproduction device comprising: a first signal input terminal for inputting a luminance signal; a second signal input terminal for inputting a first color difference signal; a third signal input terminal for inputting a second color difference signal; YC separation means for separating and outputting another luminance signal and a carrier color signal from a composite video signal; and color difference decoding means for inputting said carrier color signal output from said YC separation means, and decoding and outputting another first color difference signal and another second color difference signal; input signal switching means provided between one terminal selected from said first signal input terminal, said second signal input terminal and said third signal input terminal, said one terminal used for receiving said composite video signal for said YC separation means; switching means for inputting a component video signal input in said one terminal used for receiving said composite video signal and one of an output signal of said YC separation means and an output signal of said color difference decoding means, and outputting one of the signals input therein; and signal switching control means for outputting a signal for switching said input signal switching means and said switching means.
