Abstract

Apparatus for processing signals having time base variations comprises: time base variation correction circuitry for correcting time-base variations existing in a signal input thereto and having an input terminal and an output terminal, the output terminal providing signals which are time base variation corrected; a recording and/or reproducing unit having an input terminal for receiving a signal to be recorded on a recording medium and an output terminal for providing a signal reproduced from the recording medium; and switch circuitry operable in a recording mode for connecting the output terminal of the time base variation correction circuitry to the input terminal of the recording and/or reproducing unit and in a reproducing mode for connecting the output terminal of the recording and/or reproducing unit to the input terminal of the time base variation correcting circuitry. The processing apparatus is further adapted for processing for recording a first signal having time base variations therein or a second signal not having time base variations therein, wherein in the processing of the second signal, the time base variation correction circuitry is bypassed and the second signal is furnished directly to a recording unit.

Dependent claims

A composite color video signal processing apparatus for processing a composite color video signal containing a luminance signal and a color information signal, comprising:

(A) recording/reproducing signal processing means arranged to receive said composite color video signal and to transform the received composite color video signal into a component color video signal consisted of both the luminance signal and color information signal and to perform either a recording signal processing or a reproducing signal processing to both the luminance signal and color information signal, and to transform back into the composite color video signal the component color video signal processed by either the recording signal processing or the reproducing signal processing, thereby outputting the composite color video signal;
(B) recording/reproducing means arranged to record on a recording medium the composite color video signal processed by the recording signal processing outputted from said recording/reproducing signal processing means or reproduce the composite color video signal recorded on said recording medium, thereby supplying the reproduced composite color video signal to said recording/reproducing signal processing means;
(C) time-base variation correction means arranged to receive a composite color video signal add to correct a time-base;
variation generated on the received composite color video signal:
and
(D) switching means arranged to switch connection between said time-base variation correcting means and said recording means, in such a manner that in a case where a composite color video signal supplied from other reproducing apparatus is input, said composite color video signal is supplied to said time-base variation correction means and to correct said time variation generated on said composite color video signal in said time-base variation correction means, thereby recording on a recording medium the composite color video signal processed by the recording signal processing of said recording/reproducing signal processing means and then reproducing it and, in another case where a composite color video signal processed by the reproducing signal processing in the recording/reproducing signal processing means is input, said composite color video signal is supplied to said time-base variation correction means and said time-base variation generated on said composite color video signal is corrected by said time-base variation correction means and then to output it.
