Still confused about HDCP/HDMI

So not too long ago we heard that movie studios would most likely *not* start to degrade HD content for non-HDCP-compliant displays and players/video cards until 2010 at the earliest. Considering this, what WILL HDCP really impact over the next four years? Nothing at all?

And also, can someone clue me in as to what the point of HDMI is besides providing HDCP? Would HDCP/HDMI even exist if it wasn't for the movie studios trying to prevent pirating? Are either of these technologies something I should be excited about in the slightest?

Just some questions I've had that are difficult to get answered from reading articles and old threads. Thanks.

Probably not. They are having enough trouble getting HD-DVD\BD accepted. If they were to require HDCP as well, it would all but kill it.

HDMI is an improved version of DVI. You can do HDCP over DVI so you don't need HDMI.

How can this possibly be a good thing unless you're using the integrated TV speakers?

Um... because you've got a good receiver?

You heard wrong. It is analog outputs that will not be degraded, digital outputs need HDCP.

I still don't believe they'll do it right off the bat. Would piss off too many customers.

I still don't understand why you'd want your audio and video in the same cable. Are you going to run your video signal through a receiver??
 
It can run both it doesn't HAVE to run both. Over all is just a nice cable that can carry high quality video + audio in one package. I see no problem with this...

HDCP is required for digital output, be pissed if you like.

Why wouldn't I? Most high-end (and probably low-end, soon) AV receivers do just that. One possible advantage is upscaling _all_ of your component video sources, not just whatever ones the manufacturer decided to spend the money on an upscaler for (ala the Denon AVR-5805). It also simplifies AV pairing.

Also, your TV only has so many inputs. A serious console gamer, for instance, is going to run out of component inputs in a flash, since every console this generation (360, Wii, PS3) and last (Xbox, GC, PS2) has had them. Want an upscaling DVD player, HD-DVD player, and BR player? You'll want at least three digital inputs. Why limit your TV choices just because of something like the number of inputs?

I understand, I didn't think this was something you could do. Does sound convenient. So you would hook up, say, a DVD player with HDMI to your receiver, and then run separate analog/digital outputs from there to your sound system/TV?

TheSnowman, when you say required, do you mean, won't play without it, or, studios will choose to degrade content without it?
 
I mean won't play without it. As for hooking stuff up, if you have HDMI to the TV you can and video and sound from all sources on that as well as be able to output surround sound direct from your receiver.

Well I'm assuming then that all non-HDCP TVs have analog inputs, and those that have digital almost definitely DO support HDCP?
 
As far as new HDTVs go anyway, older ones are a bit hit and miss. Monitors are a whole nother matter, but they are coming around now.

I mean that in respect to digital inputs, analog inputs are almost always an option.

If they have HDMI, it's a pretty good assumption. If it's just DVI, it's a lot less likely. I bought an LCD TV this year, for instance, that had DVI and no HDCP. (My thinking was that by the time HDCP really becomes an issue for us, we'll probably need a new TV. So far, so good.) Safest bet is to always check first for HDCP, not assume anything.

As someone else pointed out, it's quite rare to not get analog inputs with your TV/monitor. If you have an AACS protected media with ICT turned on, analog and unprotected digital outputs will render at 540p. The good/bad news is that by the time ICT gets seriously considered again, HDCP uptake will be considerably higher than it is today.

Could you elucidate on that? Having read several news blurb indicating most major studios will not be using the ICT with their HD movies in the near future, how will the quality be degraded?

not true at all.
 
Well DTCP standards and various levels of WMDRM are also authorized for digital output under the AACS agreement, but you aren't going to find a DVI port supporting either of those.
