Thanks for the info, but I've already done the color correction. It's the timing that I need to fix. My tv rolls when it's given a PAL signal. I was hoping there was a way to introduce blank frames or something into the composite signal. That way I could increase the signal to 60Hz and not disrupt the timing of the game. Maybe 1 blank frame for every 5 frames of video should do it... But I need the spec's on composite video in order to decode the signal Rob Kean rkean@scsn.net -----Original Message----- From: Mike Keitz To: rkean@scsn.net Date: Friday, March 13, 1998 4:48 PM Subject: Re: Composite video standards and specs... > >On Fri, 13 Mar 1998 15:05:36 -0500 Robert Kean writes: >>Does anyone know where the best source for this info is? >>I would prefer to get the info off of the 'net (I'm too lazy to go >>searching >>the ee shops and bookstores) ;-) > >This has been written up on the net.
