ABSTRACT:
The disclosed system for correcting excessive horizontal blanking of color television signals, separates the luminance and chrominance components of the television signal, separately expands or stretches the luminance and chrominance components, corrects the error in the color subcarrier caused by expansion of the chrominance component, and combines the expanded luminance and chrominance components. The system may be implemented in either the analog domain or the digital domain, the latter being preferred because the circuits are less critical and the quality of performance is substantially constant.
