ABSTRACT:
Disclosed is an apparatus in which a picture signal is converted into digital signals and the digital signals are recorded into a recording medium, and which is suitable to perform dubbing of the digital signals reproduced from the recording medium. The apparatus employs the component method in which a luminance signal and chrominance signals constituting a picture signal are recorded separately from each other. According to the component method, the sampling frequency of the chrominance signal is set to be about 1/3-1/4 of that of the luminance signal, and therefore the recording/reproducing of a picture signal is carried out after the bit rate of the digital luminance signal is converted into a value equal to the bit rate of the digital chrominance signal. When digital dubbing is carried out between two apparatus each employing the component method, the taking-in and taking-out of signals to be dubbed are performed with respect to the digital luminance signals and digital chrominance signals having the same bit rate with each other.
