ABSTRACT:
Color encoding format for a color picture information record, and recording apparatus therefor, are disclosed for recording of discs for use with both (1) disc players designed to provide PAL-type outputs for driving PAL-type color television receivers, and (2) disc players designed to provide SECAM-type outputs for driving SECAM-type color television receivers. In players, up-conversion of recovered composite signal precedes comb filtering to separate luminance and chrominance components. Decoding of up-converted chrominance component, to obtain baseband color-difference signal information is followed by remodulation of a carrier pursuant to a desired output format. Comb filter arrangements of U.S. Pat. No. 3,969,757 are used when up-conversion shifts color subcarrier to a frequency in vicinity of PAL subcarrier frequency, but bearing odd integral multiple relationship to half the line frequency. Differing comb filter arrangements are employed when up-conversion shifts color subcarrier to PAL subcarrier frequency. Demodulation/remodulation arrangement involving the separate detection and remodulation use of two color-difference signals, as well as system requiring detection and remodulation use of only one color-difference signal, are disclosed.
