I have a customer defining some equipment which outputs analogue video. They have said it would be to NTSC RS-170A standard Y C (on a S-Video, Mini Din connector), however I'm not sure if they really mean RS-343A.
The difference being RS-170 is 1V blank to white, and RS-343A being 0.714V blank to white which I always thought was the common video levels. Sync is -0.3V in both cases.
Has anyone got any idea what the standard video levels would be. I assume they would be the same for Y C / S-Video as for composite.
I have tested a cheap COTS video capture device and this only accepts 0.7V, further making me think my customer really means RS-343A. Before I question it with them I'd like to get a feel for what you guys think. I don't believe they would want to output video levels not commonly commercially supoorted.
