What does "HDTV-Ready component switching" mean/entail?

Thanks

Without going into a long winded dialog about this topic go to www.google.com and type in "component video switching" and perform a search. This will return numerous topics and definitions that you can read through.

Hi Ayien,

HDTV-Ready component-video switching means that the component-video inputs are wideband, which means they will accept a progressive-scan DVD player's output as well as the signals in several formats from an outboard High-Definition TV tuner or HDTV cable decoder. These include 480p, 720p, or 1080i signals. A progressive-scan DVD player outputs a 480p video signal. The "p" stands for progressive-scan, the "i" for interlaced video.

Standard component-video inputs will accept only NTSC video. The wideband outputs are needed so the HDTV and progressive-scan signals can be switched by the receiver without picture degradation.

Unless i'm mistaken the tx-sr600 by onkyo, can handle the hdtv picture. Is this correct?

What is says on onkyo's web site:
The TX-SR600 has 50 MHz component video switching, which allows the high definition video signal to use the receiver's source switching without degrading video quality.

Thanks in advance, and thanks Alan for your useful knowledge (:

Yes you are correct, the 50MHz bandwith is sufficient for HDTV signals.

Does anyone know of an article or thread that may exist for an a/b test of using/not using the receiver for video signals?

Hi,

No, I do not, but you can do those tests yourself if you get an A/V receiver and a compatible TV display that has component video inputs. If you want HDTV, the TV display must be progressive-scan compatible. You could plug the component-video outputs of your DVD player directly into the TV display, bypassing your AV receiver's component-video switching, then use the receiver to switch the component-video output of your DVD, comparing the two to check for any picture degradation.

Regards,

I knew you were gonna say that. It's not that I'm lazy, but it is very hard to do the plugging and unplugging with my receiver in the current entertainment center I have it housed in. You'll see what I mean when I send my pics in for the wall of fame. Has anyone else been able to do the comparison?
