The Great HDCP Fiasco
Toasty16 writes "According to an article on Firingsquad, our shiny new Radeon and Geforce cards won't be able to play HDCP-encrypted content, even though they have been advertising HDCP support as a feature for a few generations. Want to watch that new Blu-ray movie on your custom built PC at full resolution? Sorry, retail graphics cards won't be able to do that; only OEM-built computers from Dell, Sony, HP and the like will have that functionality built in."
tech people need to band together and make a MUTUAL BENEFIT tech company -- one where the goal is not to profit from the world but to provide solutions for members to get around problems like this.
I don't actually know anything about HDCP, but I assume it is an "end to end" system, where every component in the stream must support each other.
Until this point HDCP was just from the video output to the display device.
This new standard is basically the OS saying that in-between the protected drive and the video card, there must now be a protected path to enable the full resolution of the HD source. The video cards will still work with HDCP equipment, it's just that HD-DVD or Blu-Ray playback will not deliver full resolution on that setup.
To be brutally honest, this is horribly depressing for those of us that know better but just acceptable enough for most users (720p being a higher res source than they were used to anyway) that few outside the technical realm will really raise much of a stink. Most will live with reduced resolution output without even knowing it; full path HDCP support will be another checkbox to move people at Best Buy to look at a higher end system (video or PC).
Stuff like the broadcast flag which does affect a wide range of viewers in a very annoying way would raise a lot more ire.

Usually one has a couple other options when breaking encryption. For example, some unscrupulous hardware company employee could release the keys to the Internet anonymously. Or, somebody posing as a manufacturer could release them as well.
Although "bricking" is a possibility with the platform, it's unlikely to occur because potentially millions of people (voters) would be quite upset.
What's more likely is somebody caught with the "stolen" keys gets sentenced prison or worse.
The key that you need is embedded in a chip such that you need a million-dollar laboratory to get at it.
I'm sure there are at least a few people in the world with access to that equipment.
The short version is that it will let the Powers That Be remotely revoke the privilages of any hardware with keys that are known to have been cracked.
Revoke the privileges of licensed, standards-meeting hardware, maybe.
What I see happening is someone building an emulator that essentially runs the player software in a sandbox that makes it think everything is fine and dandy. Of course, it will have to be updated fairly frequently as new releases include hardware disabling codes for the older keys, but that will be a game of catch-up that the media corporations will never win.
That is, assuming the technology succeeds commercially at all. I personally don't think it will take off, because there's no incremental upgrade path, or a particularly compelling reason to upgrade for the vast majority of the population. Sure, you could play a high-definition movie at quarter resolution on a regular TV, but what's the point? The DVD version will be much cheaper, and look just as good on that display. To get any benefit will mean buying a high-end TV, a new player, and media that costs more. Thanks, but no thanks. And I say that as technology-loving geek who owns hundreds of DVDs. My parents - who watch DVDs on TVs that are 10-20 years old - would probably laugh at the suggestion.

SuperAudio (it had some other names too) were a Sony technology for higher quality sound than CDs, basically, a DVD where all the capacity were used for high quality sound.
... which died a quiet death after a couple years.
Never took off - CDs are "good enough", nobody bothered to upgrade. No customers meant that record companies outside of Sony didn't bother releasing content on the format
The same will happen to these high definition video disks. You'll see.
There's no way I can go out and pay for a HD drive, a new monitor and then watch retail purchases HD content.
It's going to be downloading rips for me it would seem.
*shrugs*
I remember stumping up for a DVD decoder card back in the day - seemed a fair wad of cash, but I did like the picture. Basically it would seem the cost of entry to the new HD DRM future is going to be astronomical - nobody is going to bother...
For the average joe who watches movies on say a player in the lounge, a desktop and a laptop when out and about - exactly how much is it going to cost to upgrade from DVD to HD? How much do they possibly think I'm going to pay extra to replace my equipment that currently meets most of the specs with NEW - JUST TO GET ROUND THEIR F'IN DRM *slams head into desk* That's it - I'm sitting the next gen out.
Maybe Stallman is pretty smart to insist that DRM not be a part of GPL III after all. Do we really want to go down this path with Linux? A firm stand now might (I did say might) send the industry a wake up call that not everyone will accept intentionally crippled hardware.
Tired of all the isms, don't exploit people as an employer, or a government, mmmmK?
A highly sensible and valid point. What the hell are you doing on
There is another method to get round the HDCP trap, which is to buy one of the Spatz boxes http://www.engadget.com/2005/07/15/spatz-techs-dv
Now, HDCP also allows a revocation method - but it is not at all clear how the revoked keys would be transported. It could be that a new HD-DVD/BD disk carries them and disallows display for that disk, or burns this data into the player's NVRAM. I cannot believe that the latter would be legal ("I put this disk into my player and it broke it entirely". "Oh, yes, sorry, 20th Century Fox has revoked your television rights for using a non-approved display device". "Mother of pearl - call my lawyers!"), so we have a situation where some DVD makers could choose not to allow display on HDCP-stripping devices.
I think the way around this one would be to ensure that they lose as much money as possible on that. Every time someone discovers a non-stripper compliant disk, they post the name of the disk on a central web site (LiveJournal or some such), and we all go out and buy the disk. The next day, we all go back and return the disk and demand our money back - "Hey! This disk doesn't play on my projector. My other ones do!". Doesn't matter if you have a projector, HDTV or a HD-DVD player - we just all go out and do a consumer return. And clearly tell them why the disk is going back. This causes the studios and shops to lose more money than a simple boycott of the goods.
After a while, they're going to notice that the HDCP-stripper friendly disks sell more than the hostile ones (which they've lost a boatload on). Companies, in the end, are amoral creations designed to make profit. They are, in the round, economically rational. They will shift.
And once the device-discrimination stops, we can start the frame grabbing parties to P2P the contents of their disks. Hell, did I just say that out loud?

"Sorry, to my eyes DVDs look just fine.. and none of my hardware needs replacing for any other reason. If it ain't broke."
Exactly what I think. However, I suspect that the studios will stop producing content for our dvd players and "force" us to move to bluhddvdextraplus++

If you don't have laws like this in the US then you're mugs. Tell you what, I'll sell you a ham sandwich which includes two slices of bread. You got a sandwich, what more do you want?
On another note, if US do have this rule, isn't it interesting that ATI and Nvidia board manufacturers haven't started provided full HDCP compliance? It seems to indicate that HDCP requirements won't be necessary for another year yet...Delayed Vista? Maybe...

<plagiarise victim="self">
The average eye with 20/20 vision is capable of resolving one minute of arc, a sixtieth of a degree. This equates to roughly 300 dpi, when viewed at a distance of one foot. Let's say the average distance from a couch to a TV is 7 to 10 feet. At 7 feet, you can resolve 300/7 = 43 dpi, at 10 feet it's 30 dpi.
So in order to fully resolve a 720p picture (1469 pixels diagonally) at 7 feet, the TV would have to be at least 34 inches diagonally to make out all the detail. At 10 feet you'd need a rather large 50 incher. For true 1080p, even at 7 feet, anything under 50 inches and you're missing out - and at 10 feet you'd have to get a whopping 74 inch TV! At 10 feet, you need a 30" screen even to make out plain old standard-definition DVDs properly.
</plagiarise>
So unless you've got a particularly large TV or a particularly small loungeroom - or a projector - you may find investing in a high-definition TV to be entirely pointless. You simply can't see the extra detail. Of course, watching high-def movies on a computer monitor is different; we sit much closer to them, say around 18 inches away. At that distance, you'd want a 200 dpi screen (at 24", that's an impressive 4183 x 2353). Or you could get one of these - except it doesn't support HDCP...
Why would anyone engrave "Elbereth"?
Currently DVDs are 720 x 576 (PAL), which is good enough for me, at least for the next 5 to 10 years.
... DVD was a natural replacement and solved all of those issues.
VHS degraded over time, was awkward to use, bulky, hard to navigate exactly, low resolution
Unless you have a 60" TV and can see the DVD encoding blocks and resolution. This is a niche market though - most people (especially in the UK and Europe) simply do not have massive TVs.
So unless DVDs suddenly start shipping with poor encoding, thus trying to make HiDef discs look better in comparison, no one is going to care. I'm going to buy £20 BluRays - I only watch most films a couple of times anyway - rental seems a better option even for DVDs, TV series are worth buying, but they're less likely to be in HD anyway, or not as worthy of HD. High BluRay prices will simply mean less sales to consumers of content, and more rentals.
A good film that's worth owning is like a good book. It doesn't need the resolution to be good, it's all about the content, the acting, the story. As long as the DVD is looked after, it's all that 90% of people will need. With clever filters DVD resolution can be upscaled very nicely as well, so it will look good on most HDTVs, as long as the DVD player is decent (+ progressive output). If you can afford a HDTV, then spare a bit more for a decent player, eh?
How long will it be, though, before being "Trusted" is required for other things? Like connecting to the Internet, for example ('cause we gotta stop those damn hackers)? How long will it be before Free Software is banned entirely, since it's fundamentally incompatible with DRM (regardless of what Linus thinks)?
/. is ineffective. I ditched my TV some times ago, now I also avoid cinema because I find it unbearable to give money to someone who use it to take my rights away from me.
As great parent post said, this is only movies. Do you need movies? Do you want DRM everywhere? Then vote with your money and and stop watching those crappy movies. All off them. And tell your friends why you do it, just bitching on
And this of course does not even cover this fun scenario: I crack my unit and do not release the keys so that they do not know which one it is, then I simply keep releasing the actual movies in .avi format. Oops. How are they going to put an end to that?
HDTV sales are drying up because everybody who cares already bought one. Do you honestly expect a market that has basically already reached saturation is suddenly going to have a 100% replacement rate in that hardware? Bear in mind that the average household income in the U.S. is $49,722, which means an HDTV big enough to see any quality improvement over an ordinary DVD costs almost all of the average U.S. household income for an entire month after taxes. That's not something you just throw out because some paranoid Hollywood nutcases decide you should.
Here's my proposal, and I think we could make it stick, at least here in California: make the Hollywood studios pay a steep tax on the sale of every HD-DVD or Blu-Ray that enforces HDCP restrictions to help defray the added disposal costs of landfilling all of the thousands of glass picture tubes (containing mercury and other nasty substances) in the backs of all the HDTVs that they obsolete. Maybe that would make them think twice about this.

And if you actually read the product descriptions, it says those devices have HDCP-compliant in and out. They're just signal boosters for really long cables, they don't remove HDCP from the signal.
