100 MHz component video outputs

[radaray58]

I've recently discovered that my Harman Kardon AVR630 has 50Mhz component video outputs (at least the new AVR635 does...I'll check my manual when I get home). Many of the new receivers (like the Denon's you recommend) have 100Mhz outputs, and I believe that you score that as a minimum requirement on your testing scorecard. What is the effect of having only 50 Mhz of bandwidth? Will I have degraded performance if I use my receiver for switching instead of a direct connection from the source being used for HD or other signals? If there is an article you can direct me to, that would be great.

The maximum bandwidth required to pass HDTV signals is 27 MHz. The specs the receiver manufacturers give for their component video switching is usually -3 dB down (loss of half). So in theory a 50 MHz signal would lose no more than 3 dB and a signal about half that frequency should pass with little to no loss.
