Which is Better for HDTV? Component Video or HDMI Connections?
Courtesy of Big Picture Big Sound is a home theater basics question looking into what type of connection is better. Connecting your home theater can be a bit of challenge, specifically where to route each set of wires.
From the article:
However, whenever there is switching or distribution of an analog
signal (component video is an analog signal), you can have some image
degradation. The Yamaha receiver's component video inputs are rated for
high definition signals up to 1080i (60 MHz bandwidth), but this does
not mean there will be no signal degradation. It's possible there would
also be some small amount of degradation in the DVD's 480p connection
by switching it through the Yamaha as well, but that would most likely
be more subtle.
