Abstract

This color recorder, drawing 1, records and eventually displays a first raster line in one color, a second raster line in a second color, and a third raster line in the third color. A conventional black and white recorder can be utilized. The source of NTSC signal is applied to color demodulator 1 and sync stripper 2.

Color Recorder

This color recorder, drawing 1, records and eventually displays a first raster line in one color, a second raster line in a second color, and a third raster line in the third color. A conventional black and white recorder can be utilized. The source of NTSC signal is applied to color demodulator 1 and sync stripper 2.

The output of stripper 2 is applied to counting logic 3 which serially puts a 1 first on And 4 then on And 5 and next on And 6. The red output from demodulator 1 is applied to And 4, the green to And 5 and the blue to And 6. Consequently, the output of Or 7 is first a red line, then a green line and then a blue line. This information, along with the output of stripper 2, is then added and recorded.

Drawing 2 illustrates the playback of the recording done by the drawing 1 device. The recorder output is applied to sync stripper 9. The video output of stripper 9 is applied to amplifier 10 with the sync output being applied to color burst insertion circuitry 11 and counting logic 12. Subcarrier oscillator 13 is applied to circuitry 11 to provide the standard color burst to amplifier 10. In addition, oscillator 13 is connected to phase gating circuitry 14 which is then applied to amplifier 10. The output of amplifier 10 bus represents a NTSC compatible color video signal.
