Abstract

The present invention relates to a recording apparatus capable of recording an arm-plus (PAL PLUS) signal which is currently under trial broadcast in Europe. The present invention relates to a recording apparatus which is capable of recording a luminance signal and a color signal as well as a luminance signal, which is a signal obtained by equilibrating modulation by a BY phase of a color sub- An apparatus for recording an arm-plus video signal including a signal on a predetermined recording medium, comprising: signal input means for inputting an arm-plus video signal through a video input terminal; Automatic gain control means for correcting and outputting the level of the input video signal; Signal separating means for generating a color signal from which the luminance signal and the helper signal are removed from the video signal output from the automatic gain control means; And mixing amplification means for mixing the luminance signal and the color signal from which the helper signal is removed to generate a signal to be recorded on a recording medium. According to the present invention, the helper signal is removed from the arm-plus signal and recorded, or the helper signal contained in the arm-plus signal is demodulated and recorded in the frequency band of the luminance signal, There is an advantage that the signal can be recorded and reproduced.
