Y/C (S-video) to Composite conversion

[VEBill]

(This question really is for work.)

We have to interface several Y/C (or "S-video") video signals to a monitor that has Composite inputs. So I'm in the market for off-the-shelf, professional-grade, S-video to Composite video converters. For NTSC (North American) video.

The market appears to be swamped with cheap adapters that use the ol' capacitor trick. There are a few products that use proper active mixers, but those that I've found still do not include a luma trap (for notching out 3.58MHz from the luma signal before mixing, to avoid introducing colour artifacts). I'm looking for something better.

Can anyone point me towards any S-video to Composite video converters that actually do it correctly? With a luma trap to keep the colour stable, and with active circuitry to ensure that the output waveform is as correct as it can be.

I've already burned-up Google for a few hours. Perhaps I'm missing a critical keyword.

Thanks.

Maybe not full products, but may point you to some...

I've never seen this as "stand-alone" module.
However (don't know how many you need), there are a number of VCRs that can do this, which of course bring you into the fleabay market...

UPDATE: A co-worker bravely and ambitiously added "comb filter" to the other obvious Google search terms and found the Kramer FC-10Dxl.

"...converts a composite video or s-Video input through a digital comb filter to a composite and s-Video (Y/C) or component (YUV/RGB) video output."

That's dangerous searching... he should get hazard pay.
