Abstract

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.
