Does anyone know whether or not the JVC RX-9010VBK receiver (or any low to mid-priced A/V receiver) can truly pass HDTV and progressive DVD signals thru its switchable component video inputs?

The product literature says it can pass "high definition" video without specifying the bandwidth - JVC customer service has not returned my request for info.

Any technical clarification would be appreciated, before I buy component interconnects that are useless!

Chris,

I have never seen YET a receiver low, mid, or high end that is switching 1080I or even 480P or 720P. 480I yes. Not to say some day they won't. The extra bandwidth needed to support the diffrent frequency's in the circut design comes without a cheep price so I'm told by a few Audio Manufactures. I would buy a good set of cables like M.I.T. and run them right into the TV and for get about Video switching for now.

Good luck

If it's component, dosen't mean it's High Def!!

The TX-DS989's video switching can transfer component video signals at 40 MHz (-3 dB). Mike

Larry & Mike,

Are you are saying my Denon 3802 can not pass my progressive scan DVD, or the HDTV from my DSS without degrading picture quality?

Thanks
Don

I dunno; without the specs, can't say... and I don't know much about these parameters anyway. But if it says so in the manual.... ... Mike

The 3802 can pass progressive scan DVD (480p), but cannot pass anything higher without degradation. HDTV needs 40Mhz or more to be passed without any significant degradation. (Some say higher..... around 50 Mhz).

Be careful when reading product specs that say "compatible with" and "can pass with -x db".

"Compatible with" merely means it will take the signal and pass it. It doesn't say anything about what comes out the other end.

More important is the spec that tells you that the outgoing signal will lose a certain amount along the way. What an acceptable loss to you is is up to you.

I think this shows an important weakness regarding the high-def medium - even people in the know have few definitive, objective facts regarding the limitations of this signal type! My main beef is that confusion over this issue is made worse by manufacturers who falsely promote specifications that they evidently know little or nothing about!

And they expect the average consumer to just trust them and buy into this technology - AAAARRGH!

Please excuse my ranting .... Chris

Rant away, Chris!

Doesn't the term A/V mean Audio/Video? Is not the A/V receiver purported to be the "control center" for all Audio and Video?

And if the manufacturers say (as Denon does), that the 3802 will pass a 480p, 720p, 1080i signal, then shouldn't we the consumer assume that the "control center" of our HT will do exactly that, with a reasonable amount of distortion (which all electronics has).

Notice the 4802 does state a 50mhz rating. The rest don't. I know my 3300 was supposed to pass DTV but it only has a 34mhz rating.

If companies are going to market their A/V receivers as A/V control centers, which is what they are doing, then they should state the facts properly.

But, who am I kidding? They can't even do that with simple power ratings.

... Greg (continuing Chris's rant!)

Actually, they expect (and they're correct) the average consumer to not care or notice technical details. This is why Best Buy and Circuit City are in business.

There has been a big discussion of this at other forums by folks with lots of technical expertise, but it still isn't resolved. Some say you want 2 or 3 times the bandwidth that the signal requires to have lossless transmission. So if the signal goes at 35MHz (just an example), some say you need a bus capable of 105MHz. Others say you need only 35MHz. Also, these knowledgeable people couldn't seem to agree on what MHz the signal actually is. I forget where I saw this thread, either hometheaterspot.com or (most likely) avsforum.com.

At this point I would say plug it in and see if you think it degrades the picture. If you don't think so, question answered!

And then there are the people who don't understand the difference between mHz and MHz.

LOL. I do. I'm just a lazy typist, which certainly doesn't help in situations like this, does it??!!!

MHz it is!

It used to drive me nuts in the computer world when people would put Kb when they meant KB, etc.

Touché!!!

My Yamaha RX-V1 passes all HDTV signals just fine. It's rated at 100MHz, -3dB. FYI, original models of this receiver were rated much lower (about 30MHz I think) and the receiver was later upgraded.
