Abstract
In a color television system the luminance signal is split into high and low frequency components, and the high-frequency luminance components are frequency shifted to above the conventional television bandwidth. A conventional receiver uses the low-frequency luminance components (Y.sub.1) and the chrominance component (C), with no cross effects between them. A high-quality receiver can be constructed to recombine the low-frequency and high-frequency luminance components (Y.sub.1 and Y.sub.2 ') giving improved luminance detail, again without cross effects with the chrominance signal. The sound signal (S) is carried between the chrominance and high-frequency luminance. A transmitter (FIG. 4) and receiver (FIG. 5) are described. The system has particular applicability to satellite and cable television.
