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."

  1. Yup by maynard · · Score: 5, Informative

    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.

  2. Re:Why not just use DVI instead of HDMI by jeffy210 · · Score: 3, Informative

    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.

  3. That was copy protection too by Myria · · Score: 4, Informative

    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.

  4. It is worse than that... by ruiner13 · · Score: 3, Informative

    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.

  5. Cycle the sources by thatguywhoiam · · Score: 4, Informative
    I haven't had this issue with my PS3 (hooked via HDMI to a Samsung HDTV) but a friend of mine has. However he has been able to resolve it by simply pressing the 'source' button and cycling back around to the PS3 input. You don't need to power down. Re-selecting the video input seems to initiate the handshake again.

    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'.

  6. It's a known bug in the Westinghouse TV firmware. by rikkitikki · · Score: 5, Informative

    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.

    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!
    Have to correct you here. This technology showed up with CD-Text in 1996. I have a disc that supports it (On the floor at the boutique, Lo Fi Allstars if you're wondering) and it will display track info on certain players (my sony car cd deck from circa 2000 supported it) but the format just never really caught on. According to this unofficial CD-text Faq here http://web.ncf.ca/aa571/cdtext.htm/ Nearly every Sony CD released since 1997 supports it, but it's not advertised and few CD decks bother supporting the format.
