Video interface standards

[jteef]

Reading Jocko Homo's post in the TOSLink optical cable thread and seeing him state that RCA cables could never reach 75 ohms...

There is no such thing as a 75 ohm RCA. Anyone want to prove me wrong?

how does this affect video signals? They are generally higher bandwidth, and dont employ any error correction. My TV has RCA jacks for the component video inputs. Is this bad? Where could I read about the standards on this and other formats(i.e. dvi, svideo, vga, etc)

Thanks

These guys have so much info, it isn't even funny:

If you were to replace all your RCA cables with real 75Ω coax terminated with real 75Ω BNC connectors, you would perhaps realize some tiny visible benefit. Remember video doesn't really have fast edges. It's analog!
