Most excellent work! I see you also use the trusty old 1881 - great chip. Have you figured out how to get around the no input signal problem? I did this by using a pulsin on the vsync - if there was no sync, software generated a gray or gradient background.

I really think I can do full overlay using only the sx - no sync separator chip at all - almost pulled it off on a 20mhz pic16f628 using picbasic, but it was just too jittery. There should be enough bang in that sx28 to sample the sync signals, and then lock on to the incoming video. As for mixing, I just spit out a 1v signal right back into the output - made a nice crisp white overlay.

When I get set up, I will post my results - good or bad!

Thanks for the reply.

Brad,
Check out my video module using the SX28 at [url=http://www.sxvm.com]http://www.sxvm.com[/url]
It's open source too.

And I'm very close to finishing a video overlay module using the SX48.

Good to have you "on-board", 
Bean.
