ABSTRACT:
A method and an apparatus for the recordation and reproduction of standard color-television signals, the apparatus including an encoder having circuitry for separating into separate signals the luminance and chrominance portions of a standard color-television signal, for heterodyning the chrominance signal from its normal frequency to a new, lower, odd multiple of the half-horizontal frequency, and for combining the luminance and heterodyne chrominance signals to develop an encoded-color signal, a conventional video recorder for recording and reproducing the encoded-color signal, and a decoder having circuitry for separating the reproduced encoded-color signal into separate reproduced luminance and reproduced chrominance signals, for heterodyning the reproduced chrominance signal back to its normal frequency and for combining the reproduced luminance and normalized chrominance signals to develop a reproduced color-television signal.
