SVideo any better?

Rayman

Has anybody·gotten SVideo to work with the Prop?

If I'm reading it right, you can use the fourth DAC resistor with TV.SPIN to generate an SVideo signal.·

But, I just read a post where Duffer tried it and it didn't work...

Thanks. Rinkscustoms example is exactly what I was looking for.

Don't know yet...· I don't think I even have an SVideo connector.· But, I'm going to find out....· I'll sacrafice an SVideo cable if I have to!

Having used S-Video, I know it delivers a crisper picture and that would be a step up ... but nothing beats VGA or HDMI. I only have one S-Video cable now .... Are there many S-Video compatible displays other than TVs?

I think some projectors have S-Video. Also, some video capture devices...

The main advantage of S-Video is it separates the luma & chroma signals thereby increasing the bandwidth (which translates to maximum resolution).·

However, on the Propeller it does have a negative side effect.· Because the color signal is no longer varying the luma signal, you don't get the wraparound which gives the high saturation $x0 and $xF colors.· $x0 will cause sync problems and $xF will just be a lighter version of $xE and the same hue.
