Title:
COMPOSITE COLOR TELEVISION SIGNAL PROCESSING SYSTEM
Document Type and Number:
Japanese Patent JPS60100892
Kind Code:
A
Abstract:
Filters are coupled to receive an uncorrected composite color television signal, which signal has been subjected to recording and reproducing operations and processed to have incoherent luminance and chrominance components, with the chrominance component color corrected. The filters separate the composite signal into its luminance and chrominance components. The chrominance component is coupled to a decoder to prepare it for subsequent encoding relative to a chrominance subcarrier reference signal that is coherent with the luminance component. The chrominance subcarrier reference signal is provided by a generator that is frequency and phase adjusted relative to the luminance component. A following encoder receives the decoded chrominance component and reference signal. The encoder responsively operates to provide a newly encoded chrominance component stabilized to the reference signal. This causes the newly encoded chrominance component to be coherent with the luminance component. Both components are then combined and coupled to a conventional line-to-line time-base corrector for correcting any time-base errors that are present in the combined components.
