Does anyone have a circuit diagram on converting a cctv bnc signal to rgb.
I used to use the Phillips 7111 device but this has not been availabe for some time.

The intention is to process a colour cctv signal using a FPGA instead of software.

I beleive you are looking for a video decoder with composite video input. BNC is a type of connector.

Analog devices has video decovers for composite video I considered at one time but I have no experience with using them.

if you are looking for a box that you plug and and it does it for you - maybe look inside and see how it works etc.
MCM electronics has a plethora of them: if you are looking to build one - it might be cheaper to buy one than invent it.. unless you are going to build lots of circuits or incorporate it in something else.

Thanks Todd & Kevin
I am looking for a circuit I can intergrate into a FPGA but may have to consider using a device off the shelf.
Im in Europe hence the delay in responding.
Thanks for your input.
