[comp.multimedia] RGBS -> Y/C

anantha@arches.berkeley.edu (Anantha Chandrakasan) (06/04/91)

Does anyone know of a chip or chips that will take analog RGB and S (sync)
signals and convert it into Y (with sync encoded) and C signals. I want to
record the RGBS video signal on a S-VHS recorder.

Thanks in advance
Anantha

Here's one : Motorola's MC1377. Take Y from pin 9 and  chroma from pin
13 (don't loop chroma back to  pin 10). You  might need some filtering
for chroma. I think this should work.
