That's a good idea, and I guess that raises another question that I hadn't thought of. Does the composite input need to have a 50 ohm termination? I haven't worked with video inputs very much, so I'm not sure what would work best. The unun transformer is a good idea, it might also be useful for a hot chassis set. Without some form of isolation, I don't think it's a good idea to add such an input to a hot chassis set.

75 ohm termination is good engineering practice for CVBS. That was a very good question to ask. Means that you're understanding things.
