The Dark Side of HDCP - Why is My PS3 Blinking?

FloatsomNJetsom writes "High Definition Content Protection is supposed to make sure you're not playing pirated content, but sometimes your devices screw up the HDCP 'handshake' (over an HDMI cable) and nothing works. This happens with some regularity with the PS3, and Popular Mechanics investigated and found a quick and dirty workaround. From the article: 'We then checked with Leslie Chard, president of HDMI Licensing, which owns the rights to the standard, who told us that HDCP is one component of HDMI that has been plagued with interoperability issues. HDCP (high-bandwidth digital content protection) is designed to prevent the interception of data — specifically copyrighted Hollywood movies — between an output component and a display. As Steve Balough, the president of Digital Content Protection, the licensing company for HDCP explains, the two pieces of hardware must exchange a key, a sort of certificate of authenticity unique to each individual device, to verify a secure connection.' The problem isn't limited to the PS3 — many HDTV cable boxes and have the same problem. The fix there? Unplugging the power cable."

why so onerous, technology?

[yagu]

It's a pity -- the articles roll in every day about yet another speedbump in the DRM saga and how DRM and "protection" in general makes consumers' lives miserable. Of course it's no surprise (to me), just a disappointment. Imagine if the energy spent trying to hogtie the general (and 99%+ totally honest and willing to purchase) consumer were instead applied to making the technology even better?

Making the technology even better rather than harder would only improve the landscape for everyone. TV would look better, content would be easier to deliver and use. Bang for the buck would be better. Access to everyone for things like "high-def" (pick your favorite pseudo-standard) would not be limited to just those with $5-10,000 to toss (with no guarantee your picture will be better, or even viewable).

Instead it's just one more betrayal.

Consider the very first CD player I purchased in 1983. I paid, well, I won't say how much I played for player that could only play one CD at at time. But it was heady stuff even back then. The player had a "pitch" slider to change the pitch of the music (though it also correspondingly sped up and slowed down the track to accommodate). It had the ability to program the songs in any order, and even program the starting time offset into a track, and stopping offset into a track.

And!, on the back, a 9-pin DIN out (I think that was the configuration), with the only mention in the user's manual for that output as "reserved for future use"! I couldn't have been more excited. I brought friends over and showed them the exciting new technology... they just drooled at the sight.

And I always saved the "for future use" output as the hook... I described digital output where liner notes, lyrics, all kinds cool things (of course including the de rigeur track information) would be output in some form that could be put up on a display, TV or otherwise. I 'splained how the digital format worked and how much storage there was available for all kinds of "future use" enhancements.

And, it never happened. The promise of excellent technology, never delivered. And (I've posted on this before), the notion of track info associated with CD technology didn't emerge until we, the people, did it ourselves! with CDDB!

Instead, newer generations of technology included increasingly large percentages of "slice" dedicated to controlling our use of the media, not improving the quality of our experience.

I say fork 'em.

Maybe one good thing will come of all of this -- people may get so fed up and annoyed with trying to get their newfangled entertainment setups to work right (or at all), they give up, buy a bicycle, or some hiking shoes, and get outdoors and see a different world... maybe even one with more return on investment.

Hmm, the article plus your comment makes me realize that the number of features/functionality is actually going down (despite what is advertised)...the quality of the products has fallen dramatically...and the likelihood of them working is next to nothing.

Isn't the logical and absurd conclusion of that going to be a smallish curvy box (with several hundred listed features that aren't yet enabled) with a single button on it, that when pressed will do nothing...and it might actually fail to do that right? The one greatest achievement however, is that it'll be really tough for pirates to duplicate the remarkable ability for the device to do absolutely nothing. As a real twist, once it is cracked by the pirates, it'll perform better than the consumer version by far...even though it still doesn't do anything.

Hmm, add a couple another button, a video screen, and that somebody will put linux on it someday, and it's a Zune!

"and that reason isnt to screw some mythical abberant 1% of the population."

No not at all, and perhaps that's a misconception. People aren't concerned about ridiculous copy protection just as a theoretical exercise, it's more practical than that.

Copy Protection (so called DRM) exists to segment the market artificially. If you buy a CD, the record company would strongly prefer that the only thing you do to it is listen to it in a CD player. In their view, putting the music on an iPod, on a home network, etc is against their use rules and they feel you should pay more for it. After all, you're getting more use without them getting more money. DRM is a way to make sure you only use it where they intend.

Same way with DVD's. While people would buy VHS and DVD to watch movies at home, the use is more complex with computers, iPod video players (zunes!), and home networking. Again, to them, this is a way to segment the market and create scarcity where none exists.

There is a multi-billion dollar industry around ringtones! Imagine if you could just rip your CD and put it on your phone! Why...that would be more money the consumer would have and less the record company would have!

To the record companies, the CD was a big blunder. Not only does it have excellent sound (which they are already charging us extra!) but you can repurpose the music to suit your needs from home stereo, to cars, to personal music players to phones, to what else is new next week. And they don't get any more money.

Yes yes, people will make illegal copies, but this loss is peanuts compared to what they see as new markets made possible by stopping you from copying your own music to another medium.

and, I don't have a problem with them trying to get more money for the same music over and over. I do have a problem when we have the government essentially on the take to support this model. It certainly doesn't benefit me as a consumer, and apparently it doesn't benefit the artist either (http://www.usatoday.com/life/music/news/2004-05-1 6-royalties-main_x.htm).

So your argument is superficially convincing, nonetheless, I think it's not the real reason for copy protection and DRM.

Reminds me of a joke...

It seems that a Frenchman, an Englishman and an American were captured by cannibals. The chief explained that they were going to be killed, skinned, eaten and that a canoe would be made from their tanned hides. BUT they could have one last wish.

So the Frenchman wanted a last cigarette. As soon as he was done with it, they killed him, they skinned him, they cooked him and ate him and they made a canoe from his hide.

The Englishman wanted a last cuppa tea. As soon as he was done with it, they killed him, they skinned him, they cooked him and ate him and they made a canoe from his hide.

Then they camne to the American. "I want a fork," he said.

Incredulous, they asked "A fork? Like you eat with?"

"Yes, a fork," he insisted. So they brought him a fork.

As soon as he received the fork, he started wildly stabbing himself all over his body.

"Canoe?" he shouted, "Here's your fucking canoe!"

It seems to me that the minds who work on DRM probably aren't all that brilliant. Most of the truly gifted people realize that there's no good way to implement it, and shy away from it. Judging from the amount of obvious holes, catastrophic bugs, and general suckiness of most DRM solutions to date, I'd guess that most of the people working on them are not brilliant programmers, but rather people we'd rather not have writing our device drivers in the first place.

Yup

[maynard]

I have a JVC 5U D-VHS deck with HDMI out the back. This is connected to a Sony HD-20 digital projector via HDMI. While these units use an older HDMI spec, they also show serious handshaking problems - often in the middle of displaying content. Not only does it take seconds to handshake, but right in the middle of a movie the screen might go blank and then I'll have to yank the power plug on the VCR to renegotiate. Fortunately, with the PJ I can just switch to other inputs to clear out whatever cruft is confusing its HDMI interface.

The PJ and deck are about three years old. I assumed these handshake issues had long been dealt with. Apparently not. So... the DRM is more than just a PITA. It's plain broken.

I refuse to believe this.

[linkedlinked]

No way. DRM is conflicting with fair use of digital content?
*gasp* Who'd have guessed?

NES, or "blinking toaster"

[tepples]

From the article

annoying little technological tic that caused the sound to cut out and the screen to blink on and off when we would launch certain games. Was it the PS3 or the Westinghouse TV? So Sony has finally caught up to where Nintendo was in 1985, right?

It's a known bug in the Westinghouse TV firmware.

[rikkitikki]

This is a known bug in the Westinghouse TV firmware. If you have one of these TVs, contact Westinghouse they'll send a rep out to upgrade your firmware.

Btw, why is a TV firmware bug in the games section? (or even on Slashdot at all?) The summary even mentions that it happens between the Westinghouse TV and cable boxes and other devices.

Re:news flash: cheap product has problems

[gallondr00nk]

I always wondered who arbitrarily decided that cheap stuff deserves not to work. The way I see it, if I paid my money for something I would expect functionality out of it regardless.

Case in point; I bought a Linksys WRK-54G 8 months ago (VERY cheap), and later discovered that despite paying good money for it the product was totally worthless as a router. Wireless connections dropped every hour or so, the box needed a hard reset every day and it wouldn't cope with any more then about 250 pipes without crashing. Needless to say it got returned a week later.

As consumers why should we accept that cheap automatically means defective? Have our standards dropped so far that we don't even expect our money to go supply functional products without paying a premium?
