Abstract

A system is provided for color correction of recorded television signals. The chroma signal is decoded to baseband using a reference subcarrier which has the same timing errors as the chroma signal. The stabilized baseband signal is remodulated onto a stable subcarrier and added back to luminance. The phase modulated subcarrier used for decoding is obtained from a phase modulator fed by reference subcarrier and modulated by the recorded signal burst phase error voltage. Provisions are made for processing signals recorded in NTSC or format by converting the PAL alternate line burst switching to an unswitched NTSC format.
