Abstract
A mode discriminating device which discriminates whether a normal mode or a high-band mode is used to reproduce a recorded video signal. If the reproduction level is too low and/or the noise level is too high, a mute signal is used in determining the discriminating signal so that an erroneous detection thereof is not carried out.
