CableCARD In-Depth 128

Atvtg writes "Ars Technica has an excellent article on CableCARD, and where it's heading. After discussing the history of the initiative and some of the technical details, they cover how CableCARD may meet its end shortly after the launch of 2.0 (the bi-directional spec) because of DCAS. The real surprise, however, is that CableLabs, which controls the CableCARD spec, has to certify computers to use CableCARDs for DVRs and the like. Ars points out that the upshot of this is that it will not be possible to build your own DVRs using CableCARDs. Will this kill the DIY market?"

    Will this kill the DIY market?

    No, but all the DRM restrictions and nonsense about having a guy come to your house to provision the dam thing will probbably kill cableCard. The DIY crowd will just record off the analog out, it's really at the "good enough" state anyway. I read this article earlier today, and I still can't figure out why anyone would want this thing. It sounds like it was mandated by congress, but the cable companies didn't want to do it so they made a device that's so crippled no one will want it.

A system won't be able to take a CableCARD unless built-in by the OEM; if it isn't fused to the motherboard it'll be married by encryption somehow to the hardware. The systems look like they'll have to be sold with an authorized OS--apparently Vista--and will have to use Trusted Computing to ensure no other OS will be permitted to control them.

      Not an option. My cable box doesn't have an analog out for HDTV. It has an HDCP stream coming over the HDMI cable.

      I was perfectly happy with my analog-based ReplayTV, but it was relegated to the "little" TV once I got an HDTV set. I had to pay to lease the Comcast DVR cable box since it's the only game in town for recording HDTV. However, it sucks -- the software is more buggy than the ReplayTV software ever was, and the interface is much less friendly than the ReplayTVs. Plus, with the cable company firmly in control, they don't let me do things like "hide" unwanted channels. Like I'm ever going to watch QVC, or why I'd want to skip over 60 pay-per-view sports slots that I'll never watch?

      Yes, my TV has a CableCard slot, and yes, it's most likely going to sit there unused forever. I want a DVR more than I want "one less component".

        • It's even more simple than that: all it takes is ONE of our European or Asian friends to capture a stream and post it on a torrent site. If HDCP does lock down home video recording, I'll drop cable and get all my entertainment via bittorrent.

    So, the industry has been working on these cards since 1997 or so. The biggest hurdle seems to be how to encrypt the video stream umpteen times because they're dead paranoid about hackers. As a result, 8 years later, the technology is ready but is already outdated because consumers started demanding more from their cable provider (thank you TiVo) and the 1997 designed cards couldn't handle it.

    Oh, the industry says, lets fix that in the 2.0 release. So they begin work on it. Unfortunatly, that's still vapor and it looks like the 2.0 release might be ready just about the time it's getting killed off by yet another technology.

    Why does it take so long to develop these things? Well, a big reason is that they have to figure out new and exciting places to encrypt the datastream again. Also, there is a requirement to make it as annoying to the end user as possible by denying them the use of their DVRs and making it so you have to buy your computer from an OEM if you want to watch TV on it. At the end of the day, if the technology actually takes off, it will probably be hacked anyway (probably with mod chips/special remote codes for TVs and DVRs that enable the output regardless of state of the no-copy flag).

    Basically, this is a technology that the cable companies didn't want to implement in the first place (Congress forced them to), and they've done everything in their power to make it unappealing to the end user to discourage adoption and let them extend the deadline passed by Congress and the FCC for as long as possible. It's also an example of DRM concerns basically killing what would otherwise be a pretty decent product.

      OCAP defines a set of APIs, but it is not dependent on CableCard or on DCAS. There is some independence from the underlying security implementation.

      CableCard is technically difficult, which has led to delays. However, the main reason DCAS will supplant CableCard is that it's cheaper, and it probably will be more secure. Cheaper is better for everyone.

    Computers are getting faster -- I have a ...to hell with what I have...MY WIFE has a 1.4GHz box I built for her two years ago. I can now build her a 64 bit box with dual cores today.
    This will not remain safe for one very good reason: It is more fun to show these people how STOOPID they are by breaking their multi-level encryption than it is to sit and watch the latest crap spewing out of televisions.
    Entertainment, though not the kind the cable and satellite companies envisioned, has taken a GREAT step forward. :)
    • Umm, it's not layer upon layer. It's the same encryption with different keys at different times. One set of keys for the cable transmission. One set of keys from the cable-card to the host decoder. One set of keys from the decoder to the display device (if the decoder is not in the display device). None of them are weak encryption. The HDCP system used from the decoder to the display device has been in use for about 3 years, no one has cracked it yet.

      Having said all that, I'm not really looking forward to our digital future. :(
      • It's been cracked, by someone in the Netherlands I think, but they refuse to release their findings due to the DCMA. I'd link it, but I don't know the link offhand, and I believe a comment earlier on had a link to the same page.
      • Re-encrypting the same message multiple times with different keys is the WORST kind of security problem. This is one of the clues the allies used to break enigma. By providing the same signal encrypted with different keys you will reduce the cracking time by many orders of magnitude.
        • That's true, but a reasonably well-designed crypto system (well-tested by smart math guys) isn't easily "puzzled-out", and that's what you'd need to do.

          What I mean is, supplying a static message enrypted with a ton of different keys will help you break the entire encryption system, but there's no "easier" way to decode one specific message other than figuring out the whole system. And what are the chances of someone "solving" AES? Once someone figures out P=NP I guess...
        • Not necessarily true. Check out 3DES for an algorithm that rotates different keys through the same algorithm to effectively increase the strength of the encryption. Note that distributed.net has sucessfully brute-forced a single DES encryption, but never 3DES. It's far more important that an encryption algortihm have a sound basis for being secure. No one has ever come up with an attack on DES that's better than brute force. That's pretty much as good as it gets! Well, except for the key length issue.
    • Breaking encryption has almost nothing to do with how much computing resources you have available. Most modern crypto system are designed so that, using the best known attack, it would take every computer on earth working together the current age of the universe worth of time on average to find a key.

      Your wife's dual core amd system is worthless.

      Crypto is broken by circumventing the crypto entirely, by stealing (not cracking) the key, or by finding fundamental design flaws in the cryptosystem itself.

    You can't kill the DIY market, because they will always be there. They create demand, and where there's demand, there's supply. It's what commerce is built on. Yes, the end game that those fat cats want is to control everything from lens to living room, but people outside that system will find a way. It may be illegal at first, it may be bread boards for a while. It might be something you have to import, but in the end, DIY will still be there.

    The real question is, Will DIY really mean DIY, instead of buying a computer, adding a capture card, and installing a ready-to-go program. DIY moves in cycles, it starts as a real nitty gritty DIY where people are building stuff from spare parts, creating solutions that didn't exist. Doing it cause they just want to make it happen. then others get infected with the idea, ideas are shared, innovations fly, people collaborate. Eventually some one else wants to make a profit... blah blah blah ... I'm rambling here. But the point I'm making (somewhere) is that there is a lot of motivation here, and potential profit. So it will find a way.

    The article gets most things right, except the part regarding OCAP--the middleware layer that permits interoperability. OCAP was developed long before DCAS and its purpose was not to enable DCAS but to enable retail interoperability. The CableCard enabled set top boxes or TVs to operate on any network, because SA networks, used primarily by Time Warner Cable, are not compatible with Motorola networks (used primarily by Comcast). The CableCard removes the network dependencies from the receiver. Along with a variety of other features, OCAP enables the network independent receiver to actually be able to tune to programs on specific network, because the electronic program guide data is proprietary to the network. Thus, the cable operator will write a specific application that will run on top of the OCAP middleware on any receiver on its network that will decode the proprietary guide data to enable an interactive program guide for program selection.

  • Why all of the end-to-end encryption? Is having people record TV shows to their computer, and even sharing them with the world, really that bad? I mean, I get cable even though I could realistically download all of the shows I want to watch from P2P networks and I suspect that the vast majority of TV-watchers do likewise. Why cause so many problems for your customers and raise prices so much for a something that really isn't a threat to marketshare?
  • I work as a contractor for a company that is implementing an OCAP stack for some major MSOs. The dates that the article gives for the release of the DCAS technology are a bit off. One of the cable companies plans on doing field trials this summer, followed by a full deployment of the OCAP stack probably early next year. As for the ones who think that all encryption here is evil, some of it does serve a good purpose. Most of the conditional access is to restrict people from getting pay-per-view when they

    My MythTV box does a great job recording / timeshifting / removing commercials / transcoding broadcast HDTV stations. So, I think the DIY PVR boxes have a life left for the immediate future.. I can still record Lost, and The West Wing, along with many sporting events.

    The biggest hurdle I have seen developing is with more sporting events. Events that would have been on broadcast TV in the past are often on ESPN ( e.g. next year Monday Night Football is on ESPN-HD, not ABC). If that trend continues, I have to decide whether to stop watching that program/event, or to go to a commercial PVR. Most shows I can easily live without.. the exception being ESPN-HD... when my MSU Spartans are playing basketball in HD, I am very tempted to go to the cable companies crappy PVR.

    But what about a DVR?" you ask, and with good reason. The cable company did not build all this encryption into the product only to see it thwarted by a digital video recorder that outputs an unencrypted HDTV signal to the television. Therefore, if the host device is not a display device, it is required to encrypt the video stream yet again for transmission to another device. This last type of encryption is "link encryption" such as HDCP, which Vista will also require between the PC and the monitor in order to display protected content in its full high resolution glory. It is likely that other operating systems (e.g., Mac OS X) as well as consumer electronics will use HDCP too.
    Someone is obviously spending a lot of research time and money that won't really improve their product.

    I mean seriously, if your company is spending money (and lots of it) on technology just to restrict what a customer can do by removing features, then you might as well be shoveling money into a gaping fire pit of doom.

    For an anology as think it as if a Microsoft Office project manager showed up at a meeting and said "Hey guys! I'm going to get us a million dollar budget so we can find out how to remove the Save feature for Word and Excel! Our customers will be so pleased they'll buy two copies of Office for every computer they own!"

    They have put a great deal of effort into something that won't earn them a cent of profit. The majority of people who were going to use DVR aren't going to pay twice for things and if you try to force them to then they'll probaly go elsewhere for their movies (DVD, satellite, or iTunes Video).

    On the flip side, I'm sure it keeps techy engineers employed helping them spend all this money on HDCP.

The insanity of all this is that even if HDCP somehow survives despite its obvious flaws, somebody can still rip a master. It's digital, IT ONLY TAKES ONE! How can they not understand this?!

      The beauty of that is they don't care. Not in the slightest.

      The cable companies are not making these calls, its the media companies forcing it on them. If the cable companies lose 1% of people in order to be able to continue to provide content for the 99% who don't care, if you think they spent even a millisecond worrying about you as a customer, you're horribly mistaken.

      If you want to see the mainstream media, you play by their rules. You can try going anywhere you want, but the same restrictions are coming for satellite. Via the broadcast flag, they will eventually come for OTA as well.

      • As the OP said, its digital. It only requires one copy to be ripped then its broken for all time.

        The question I have is, does implementing all this DRM (more specifically, restrictions on what cable boxes and cablecards can do with the output once its decrypted, the DRM on the actual cable signals does serve a valid purpose) achieve the stated goal of making people pay for their content instead of downloading it off BT?
  • The really annoying thing about cablecards is that they were supposed to break the cable company's monopoly on set-top boxes. But as the article says, the existing 1.0 cablecard spec sucks so badly it makes the cable company's STB the only viable option for almost all users. With a cablecard inserted in your TV, you must live with these limitations:

    1) No interactive menu.

    Are any Linux users playing DVDs on their systems? Are you watching MPEG videos and MP3s? Did you pay the required license fees to do so? Then why do you care that a DIY HDTV PVR will now be (borderline) illegal as well? People want freedom, but they aren't willing to make any sacrifice to get it. So here we are.

    If you want to see a change, people need to cancel their monthly subscriptions en masse, and stick to OTA out of spite. Or, just don't pay the additional charge to upgrade the equipment and subscription to HD.

    Finally! A topic on /. that I have some experience with!! As a cable technician, I deal with this particular headache at lease 10 times a week.

    Cablecards are an example of what happens when Congress decrees that a certain service provider must provide the service Congress's way, instead of letting the service provider do it in a way that is guaranteed to work. CableLabs created the cards with a specific set of requirements for the firmware for correct operation. Some companies (LG for example) wrote their TV firmware along the direct specification. Other companies, such as Sony, Sharp and Mitsubshi took the liberty to write their firmware however they damn well pleased. In fact, we have an entire binder full of TV makes and models with known firmware issues.

    I've never seen a problem using a Cablecard in an LG TV; it's pretty much plug it in, wait for the authorization numbers to display on screen and call them into the office for initialization. If I had the cash for a flat panel plasma to hang in my living room, it would be an LG, and I would get a Cablecard for it. Other brands, however, present a wide variety of issues. For example, any channel in our lineup that uses a 64 QAM data stream will no properly display on a Mitsubishi TV.

    Another problem is in the specifications: Cablecards are one-way devices. They do not operate along the return path, which means no Video-on-Demand, no interactive pay-per-view, and so on. You're also stuck with the interactive guide that your TV firmware came with. Troubleshooting these ALWAYS requires a truck roll, because since they are one-way only, we can't hit them from the office to return an error message like we can with our DCTs. (We use the exact same boxes shown in TFA).

    In response to some of the comments made about a MSO-issued settop box, we don't charge the monthly equipment fee for our digital equipment to milk more money out of customers; we do it to attempt to break even. A typical MSO loses anywhere between $75 to $100 per average digital subscriber due to failure to use common sense. Last week, I replaced a $500 DVR for a woman (at no cost to her) who had started putting her old newspapers on top of the box. It eventually overheated and died. I asked her why she had put them there, and she said, "Because my computer monitor got too hot with them on top of it, and I didnt want that to burn up." And just today, I replaced $700 of equipment for a family that had moved. They put their equipment in a box in the kitchen, and proceeded to improperly attach a dishwasher hose and flooded their own house.

    Anyhow, back on topic, cable companies will try to steer you away from the Cablecards to their equipment because they know it will work. If our equipment isnt working, we replace it and make it work. With Cablecards, we are stuck trying to make third-party firmware play nice with someone's TV.
    • If it's true that these other electronics companies' products aren't fully conforming to the spec, then it should be simple to objectively prove their non-conformance and get them to change it. Someone like CableLabs ought to be certifying each company's implementation before allowing them to slap on a "CableCard compatible" logo on their products and literature. The fact that you're seeing compatibility problems means either the spec is broken, or the certification process is broken. The basic idea, freein
      • You agree then that the cable companies should monopolize digital cable, forcing second rate digital boxes on the masses, forcing them to pay more for something that should work better, instead of buying potentially excellent 3rd party options.

        You also agree that I am forced to use some poorly implemented interface to navigate digital cable content instead of allowing 3rd party developers to create more rich and robust interfaces allowing for quicker searching and selecting of digital cable content.
