I know more or less zilch about the design details of component video switching, but I can see the need for certain consideration in that design.



How big a copper wire? And is it a wire at all, or a lead on a printed circuit board? How big a lead? How close to other leads? How susceptible to interference from elsewhere in the piece of equipment (power supply, other portions of the component video signal, other component inputs that might have a signal coming in but not be in use, radio tuner, analog audio sources, ...)? How does the unit switch between inputs -- some sort of relay-driven mechanical switch (very doubtful if it's in a receiver or pre/pro) or some electronic switch on the PCB? Those are all questions that come to my mind, but that I have no answers to. I do know that I've been hearing for as long as I can remember now that it's always best to keep the signal path simple (logical, since KISS is a pretty consistently good engineering principle), and that it is particularly true of component video signals since inexpensive component video switching is said to potentially degrade the signal. That may change as component video is becoming more and more common in mass market gear. *shrug* Until I have a TV with component inputs (assuming I don't end up skipping directly to DVI, as I think I'll be sticking with my Mitsu for at least a couple more years), it's nothing I will be messing with first-hand.
