Nealh,
First, COMPONENT video cables (which carry HD video signals) are made up of a triplet of RCA cables/plugs.
Say you have MORE than one source for High Def video (e.g. Dish and DVD) and that EACH has Component video outputs. Your HDTV has Component video inputs (ONE SET). Say you are watching video from your dish and you want to watch a DVD.
If you don't have COMPONENT VIDEO SWITCHING on your receiver, you have to get up, go behind your AV equipment, pull out the wires from the Dish box to the TV, and plug in the wires from the DVD player to the TV. Or you have to buy a separate piece of electronic equipment to "switch" the video from one SOURCE to another SOURCE, and send the signal to your TV.
But, if you have a receiver with COMPONENT VIDEO SWITCHING, you plug the COMPONENT video cables from the Dish Box into the receiver COMPONENT IN 1 jacks and you plug the COMPONENT video cables from the DVD player into the COMPONENT IN 2 jacks. Then connect a cable from COMPONENT VIDEO OUT on the receiver to the back of your HDTV. Now, if you want to change from watching Dish to watch a DVD, you pick up your receiver remote and press the DVD button--that's all you have to do. The receiver now chooses the right video signal (from DVD) and sends it to your TV. Hopefully you also have your DVD audio connected to the receiver and the receiver plays the correct sound through your speakers.
It's really basic, just like switching audio sources through your receiver. Only many AV receivers in this price range do not include COMPONENT VIDEO SWITCHING because it adds cost.
Most AV receivers DO include SVIDEO switching and COMPOSITE video switching, but not COMPONENT VIDEO SWITCHING. That's what makes this one just a little bit more special!
