Title: Cross-colour eliminating apparatus for a television receiver
Inventor: SASAKI REIICHI
IPC: H04N9/64
Filed: 1969-06-24
Abstract: 1,268,963. Colour television. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. 24 June, 1969 [26 June, 1968; 29 Nov., 1968], No. 31909/69. Heading H4F. The invention relates to the elimination or at least reduction of cross-colour interference produced in band-sharing colour television systems, e.g. NTSC, PAL and "SECAM" (Trade Mark) systems caused by unwanted components of the luminance signal being present in chrominance channel. This is effected by means of a prediction circuit which produces a control signal when cross-colour interference is likely to occur, this control signal being applied to the chrominance channel to interrupt the chrominance signal for a time interval sufficiently long to reduce or eliminate cross-colour interference. As described, Fig. 3, the prediction circuit includes a narrow bandpass filter 11 which separates frequency components near 2 MHz (for the NTSC system), from the composite video signal, i.e. adjacent the lower frequency end of the chrominance signal band, and the existence of an output therefrom (contains only luminance components) means that there may be luminance components in the frequency range 3.58 MHz  0À5 MHz, i.e. the chrominance signal band, and that therefore crosscolour interference may occur in the reproduced image. The output of filter 11 is supplied to a full-wave rectifier 12 and converted into a unidirectional signal which is transmitted via a non-linear circuit 13 only when it exceeds a threshold level to a waveform shaper 14, the output of which closes a gate circuit 15 and thus prevents transmission of the chrominance signal. Waveform shaper 14 which may comprise a oneshot multivibrator produces a pulse in response to an output from the non-linear circuit which is less than one micro-second, preferably 0À7 micro-second, since to suppress the spurious effects only, the chrominance channel must not be interrupted for more than one micro-second. Although the gate circuit is shown between the chrominance amplifier 6 and demodulator 7 it may be positioned anywhere in the chrominance channel or between the colour subcarrier oscillator and demodulator. In a second embodiment, Fig. 4, gate circuit 15 has two control inputs, the first 15a being the same as in Fig. 3 and the second 15b being supplied with the chrominance signal envelope 16 via a non-linear circuit 17 and is arranged to allow transmission of the chrominance signal regardless of the output of waveform shaper 14 when the amplitude of the chrominance signal envelope exceeds a predetermined level. This prevents spurious colour elimination in a part of a saturated colour picture.
