I see Y before delay processing available on pin 46 (IC301 - Y/C combining is performed by IC internally) - Y delay is 1 line long easy to implement in software. http://www.datasheetarchive.com/dl/D...SA00350070.pdf I would advise to use buffered signals (video opamps are cheap and widely available today). Your current problem with S-Video capture can be solved by removing chroma signal in frequency domain from luma plane (defreq?). Last edited by pandy; 14th October 2014 at 12:23. |

How do you use S-Video?
Is it through SCART? As some S-Video (Like SCART in most cases) are not Real S-Video, but simply Composite. And using that will result in much crosstalk (As Luma and Chroma is separated in S-Video, but if it's Composite in it it will be Luma = Luma/Chroma, Chroma = Luma/Chroma. And you can guess the mess. Usually you get like a checkboard pattern with colored dots that falls down, yours is much more extreme, i am guessing it's some grounding issues. Still all just a guess |
