RGsB circuit

[Rob 78]

I need a circuit for an RGsB output.for a mitsubishi TV monitor. I can get an RGB Input with separate composite video from my DVD recorder scart but I need to strip the vertical and horizontal sync from the composite video as the scart composite input on the scart is the only source of sync. I then need to put the combined sync back on the green signal. A circuit or a known piece of test equipment to do this would be very much appreciated.

There's some info here, but if it's a TV monitor can't you select separate sync anyway?

DIY - LM1881 Sync Stripper This page will show you how to use an LM1881 chip to "strip" the sync information from composite video, for use in an RGBs video signal. You do not need a sync stripper for SCART equipment, but some monitors and BNC switches might require them. Please only use one if yo
