ABSTRACT:
Color T.V. signal information is transmitted from a receiver into a recorder, from a transmitter to a receiver, from a color T.V. camera into a transmitter, or the like. The luminance component and the chrominance component are alternately applied to an analog-to-digital converter, during alternate respective field-periods (half-frame periods) of the T.V. signal. Produced at the output of the converter is a signal in which the digital chrominance information alternates with the digital luminance information during different respective field-periods of the T.V. signal. Although a single analog-to-digital converter can be used, the sampling frequency for the analog-to-digital conversion of the two different components can be of different respective values.
