The invention concerns a color television camera for providing a color television signal suitable for recording. The camera comprises separate transducer means for deriving the luminance and chrominance information bearing signals, the transducer means being controlled so that the color information scanning takes place during the line frequency flyback of the luminance scanning. The luminance and chrominance signals are subsequently interleaved by time division multiplex and the resulting signal can be recorded by the use of simple magnetic recording devices.

Color television camera with time multiplexing of luminance and

A color TV signal is recorded on an information carrier and includes a luminance component which occupies a predetermined luminance frequency range and a modulated chrominance subcarrier. In a conventional color TV signal, the modulated chrominance subcarrier occupies a first chrominance frequency range having a predetermined location relative to the luminance frequency range. However, the modulated chrominance subcarrier is assigned a different second frequency range which has the advantage that the modulated chrominance subcarrier in such range is easier to record. A color TV picture is to be reproduced from such recorded color TV signal. Firstly, there is introduced into such color TV signal a corrective phase shift bringing the signal into synchronism with a studio synchronizer. Only thereafter is the modulated chrominance subcarrier frequency-translated from the second back to the conventional first chrominance frequency range to thereby form a conventional color TV signal.
