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."
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.
FYI, DVI also uses HDCP. HDMI is basically pin identical to DVI, it just includes support for audio as well, so it's really the DVI spec that supports HDCP. I'm running a HDMI-DVI cable from my cable box to my Samsung DLP. Every so often when I turn on the TV after the cable box I'll catch the HDCP warning message for a brief second before it display the picture.

Notably the PACE 551 HD. I had a loaner until the PVR came in, and I'd lose the HDMI connection daily with an error message stating my TV wasn't HDCP compliant (it is). I used to have my doubts about DRM. Not any more. Now I am convinced it is evil, treats consumers like criminals and is defective by design.
The blinking effect from the NES was the copy protection check failing. The copy protection chip would reset the NES after a second if the cartridge didn't respond properly.

Ok, to start off, I have this problem with my cable box, too. If I leave the cable box on, and simply turn the tv on or off (as most people do, i bet), when I turn on the TV, the cable box tells me it couldn't establish an HDCP connection. To actually get them to handshake, both devices have to be turned on at the same time. What a bunch of BS.
The bigger problem than handshaking issues is that there are apparently multiple versions of HDMI, the latest being 1.3. Now as a consumer, how the hell am I supposed to know which version of HDMI each of my devices have? Has anyone actually seen a version number in the specs for any device? The PS3, for instance uses the 1.3 spec. If my TV uses the 1.2 spec, anything that needs to use the 1.3 spec won't display content. How are they going to explain that to the user? "well, see, the HDMI port here is actually different than the HDMI port here. They look the same, and have nothing to distinguish one from the other, but TRUST ME, there is a difference." I expect that excuse won't fly in any court should a class action case be filed. If I ever get a PS3 (after it is... oh... half the price), and it refuses to play at full resolution because my TV is only 1.2, I will be mighty pissed off. The whole HDMI/HDCP thing is totally pointless and will end up being a royal pain in the ass to everyone except the content makers.
today is spelling optional day.
In this case the issue isn't the PS3 but rather however your television handles the HDCP handshake. As I said, mine doesn't have an issue, but I do see a brief burst of noise when a game handshakes.
Its too bad, because HDMI is a really nice connection. But HDCP is just ass. I hope Sony can do something with the firmware to alleviate the issue on these sets that 'blink'.
If Jesus wants me it knows where to find me.
But as for the other 99.999% of the population who will be screwed by it...We're out of luck.

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.
HDMI to DVI adapters are easy to get, but it doesn't make a difference. HDCP is still present on the DVI connections.
Absolutely true. The Westinghouse is a MONITOR, it doesn't include any tuners (not that you actually need them if you have a Cable/Satellite/TiVo serving that purpose already).
:) ).
Westinghouse models are cheap as dirt (comparatively). Their picture quality also seemed more washed out and less crisp than other higher priced models. (i.e. most other models)
I ended up getting the Samsung LN-S3251D (of course its in the 32" range, so it only goes to 720p).
Its not quite as cheap as the Westinghouse (still half the price of the high-end models in the same price range, for comparable quality and lots of inputs)
Its been solid, reliable, and I haven't had any issues connecting a PS3 or HD-DVR to it via HDMI (like I said, lots of inputs, heck, even my VCR tapes look good on it
I'd highly recommend it.
Its like buying CPUs, you don't always need the "top of the line" (since the price jumps so much), but you don't want the bottom of the barrel either.

I have a 42w2 that was a first generation version. It has massive issues with the PS3 in 1080p mode. Basically it was sparkling on edges of any items.
It turns out that the version of it released in the first 2 months had a chipset in it that didn't comply with some specification... so it can't simply be flashed.
HOWEVER, though getting an actual RMA number took a while, the process was very friendly and customer service was helpful. They're even sending me a new box so I can get my new version.
Sadly, some abusers of the system made them change their rules about sending out a new one before they receive your return, so I'll be without 720p version of TigerWoods 07 for a week... but it'll be worth it. It'll be nice to actually see movies in 1080p, instead of the 1080i I'm forced into right now.
I hear that in the meantime I can push component out at 1080p, since none of the movies require HDCP for it yet... and worry about HDMI when the new one comes.
