ことを特徴とするビデオ信号の再生装置。 A video signal having a band higher than the chroma signal band is demodulated, and a high band luminance signal is extracted from the demodulated video signal and the chroma signal after dropout correction and Y/C separation. The brightness signal of is determined by the dropout detection signal.
A video signal reproducing device characterized in that the video signal reproducing device switches to and outputs a luminance signal created from the dropout-corrected Y/C separated signal.
