HDCP Crap

[scott911]

Just a comment after reading Audioholics review of a flagship reciever, and noting that even with a sea of HDMI ports available, the review opted to hook up several things via component in order to avoid the channel changing lag due to HDCP.

Why can't the CP check be done concurrent to the video display, and not a precurser to it? In other word's - the reciever should IMMEDIATELY show the new signal -and do its check in the back- ground. If it detects a problem and suspects a copyright violation, then cut out the picture.

I can't imagine a studio, of whoever's involved, minding if a half second of unprotected video get shown before the signal if fully validated. After all, the real theves are probabaly completely unaffected, and it's only those of us who fund the studios who have to endure the pause with most channel changes - or "downgrade from HDMI cables."

I still remember the first remote control TV my parents bought for my grandparents. When you pushed the little clicky buttom, the channel actually changed right then and there!

Content control gone amok

DVI INPUTS WERE FINE,digital video interface and add a audio coax/optical cable didnt give copy protections!
In comes the sherrif HDMI, a one cable wonder that does it all !
But with the cpu and all the capatibility issues a computer has!

There is a dvi/hdmi adaptor and allows a oppo dvd player multi region playback and works because they dont use hdmi ,but give you the hdmi adaptor cable free!

Thats the only way too bypass the copy protect coded chip being installed on devices using hdmi!

Some highend amp,pre-amp companys like CLASSE have stayed away from hdmi!

The poster above has a nice say, but has some incorrect information.

HDCP != HDMI

HDCP is a separate entity and while HDMI allows for, and requires HDCP compliance with it's playback devices, the content itself does not require HDCP and the entire drive for this IS coming from studios and content providers, not from the CE manufacturers who have to make the stuff.

DVI can most definitely have and carry HDCP protected content that requires 100% of the same verification and removal.

The new PC wannabe standard, Display Port, is really no better because it maintains that same capability for HDCP.

Really, the original poster is correct that it would be nice if manufacturers simply got on board with the entire concept of making things consumer friendly, but it isn't really up to them. It's the damn content providers who are driving the ship on things.

Now, perhaps something like this may be what someone is after...

Why would anyone want that? Well, because that output video signal, for whatever reason, is missing a specific four letters which it is supposed to have. It has nothing to do with it being DVI, it's just stripped away in the box somewhere and forgotten about.

Well, if it does NOT work, I suppose you could always return it to Amazon.

That's the biggest reason I shop Amazon.com & Buy.com (not 3rd party, of course).

For that matter, when changing FM stations there is a lag that should be addressed. The receiver should be buffering two or three stations above and below the one currently being listened to (of course some people will want the nearby spectrum stations buffered where as some will want the user presets). Then, while switchig stations the receiver can present them without delay when switching.

And what about the track gaps on CDs.

We must be living at a blistering pace if 0.5 seconds (a "flash") of video delay is now becoming intolerable and a debated subject .

another thing too worry about

BMXtrix,was right, im blameing the extra step of authenicating complience from a hdmi componet on the wrong people!
I didnt no why dvi device inputed componet works, when hdmi does not?

Im sure bmx is correct,guess i was shooting birdshot everywhere!
A movement of more dvi componets could be popular considering the Marantz issues and other unfixable complience snafus!

Or the dvi/hdmi converter option may get cheaper and cheaper till the hdmi goes like the charcoal grills did,no time to wait!

We could get lucky,Obamas x-box didnt work with his harman cardon reciever and he has a hissy fit !

If you have a DVI device that works, while HDMI does not, there are any number of reasons for this to be the case. The most obvious is that you are using two different sources and are comparing apples to pygmies instead of apples to apples. A PC, for example, with unprotected content (normal PC video) should work on HDMI or DVI no problem.

But, a Blu-ray, AppleTV, cable TV, upconverted DVD, etc. which uses HDCP, and REQUIRES HDCP can come out over DVI or HDMI and may have the same authentication issues, regardless of connection type.

Keep in mind - DVI supports component video, which is not the same as a DVI digital standard that can be converted to a HDMI cable. Some people get this confused.

DVI isn't the solution nor is HDMI - the fixes have to come within HDCP standards which DVI, HDMI, and Display Port would all have to conform to. All the consumer electronics manufacturers are having issues with the HDCP standard.

You are missing the point of what that converter does. It isn't about HDMI, it's about HDCP.

If Obama wants it installed, he certainly wouldn't be the one to do it. I would certainly bet that the White House theater is properly setup and working with a control system and verified and tested functionality, warranty, and maintenance.

Probably using component video anyway.
