Will Google Oppose DRM On HTML5 Video? 399

An anonymous reader let us know that "Mozilla has committed to not implement DRM in Firefox for WebM HTML5 video even though it is theoretically possible. Microsoft has asked Google and the WebM community several other questions that still have not been answered, but this one seems more important: will Google commit to keeping WebM in Chrome DRM-free? Does our community think that is important for the open web and free software?"

    Why are we leaving the decision up to Chrome? iOS devices are a giant chunk of the mobile market and play H.264 fine, and so do Android devices and Palm's WebOS. I'm not sure about Blackberry, but it's odd that Windows Mobile doesn't support H.264 given Microsoft's support of it. Also sites like YouTube's Mobile site are using H.264.

        If that were true, that would imply that DRM is nothing to worry about.

        For DRM to be effective, it doesn't have to be unbreakable, it just has to stop some notable amount of copying (or other non-authorized usage it's meant to prevent).

        The intent of DRM is to meet legal minimums of protection to get shutdown notices for people who host tools that simplify the pirating of your content. Even DRM companies count the amount of time that it will slow down complete digital reproductions by days, not weeks. Even then some things (like DVD's) frequently hit before the actual release.

I don't see why the situation would necessarily be any different if there were no DRM at all.

      There is no way to have standardized DRM... The whole idea of DRM relies entirely on security through obscurity, and if you publish a standard then that obscurity is gone.
      Even with an obscured scheme, if it's worth it to anyone (ie there aren't easier ways to get the same content) then someone will reverse engineer the format and work out how to extract the data from it in a usable way. This will _ALWAYS_ be possible, because the player itself has to get the data into a usable format itself in order to display it.

Even if I happen to agree with the particular rule being thus enforced(which is hardly assured, most DRM users go beyond the rights copyright law allows), it is the change in the ultimate controller of the system that is the inevitable and unacceptable consequence...

      The fact that any system sufficiently robust to allow for effective DRM also allows for effective censorship is just icing on the cake...

    I spent a long time opposed to DRM because of the lock in effect. Except that reality has pretty much rendered DRM as obsolete.

    DRM does not and has not protected video game publishers.

    DRM does not and has not prevented every significant song, movie, or other work from being easily, readily, and widely available on torrents.

    DRM does not and has not generally resulted in an improved customer experience.

    In a very real sense, it is frequently easier to use the pirate version of a game than the normal one. I love the GTA series on PC, and every single game I ever purchased I almost immediately installed the No-CD cracks. Yes, that's right. I bought all the games of GTA I ever played, and I cracked all of them just so I didn't have to dicker with the stupid DRM.

    So, other than annoy the end users, what purpose does DRM serve?

    • DRM does not and has not protected video game publishers.

      Yes it does. The digital restrictions management on video game consoles protects established video game publishers from competition from smaller indie developers. Console makers have a history of not granting licenses to micro-ISVs, and "homebrew" software relies on fragile jailbreaks that the console maker can and does fix with an update to the console's firmware.

    • Door locks don't keep burglars or determined attackers out, either. So, what purpose do they serve?

      They make it hard to *casually* invade a room or building. They make it so there's at least a small hassle involved.

      I think it's more or less true that carrots probably work better than sticks -- it's probably better to combat piracy with affordable prices, convenient availability, and a feelgood sense of legitimacy. But I can kindof understand why some content purveyors would also want to do something to stop

    • Well put. As Richard Stahlman says, DRM == Digital Restrictions Management, NOT Digital Rights Management. When you purchase a personal item like a book, game, movie, music, etc, you naturally expect to be able to use it as, when, and where you wish, and to resell it if you want. DRM only RESTRICTS your choice, so in effect you have not purchased the item, but merely rented it. If one were to apply rigorously the Right of First Sale to these items, DRM would itself be illegal, in my non-lawyerly opinion.

    Right now the BBC serves H.264 streams via flash and it has pretty lousy performance (Flash) or pretty awesome performance (via the same stream in XBMC). If they want to shed Flash entirely and still serve a large proportion of the web then a limited amount of content protection is almost inevitable because the content producers (ie, not the BBC but the people who own some of the shows they broadcast) demand it.

    Sure, ideally there would be no content protection at all (it really doesn't affect the free distribution of the content at all) but right now that is just not a reality.

    I would love BBC iPlayer to be able to serve H.264 with HTML5 (it already does to iPhone user agent strings) since it would free me from the flash performance hog that makes HD streams stutter even on a powerful desktop machine. It won't happen if a sizeable portion of the browser market won't support it.

    I'm only talking about iPlayer here, but it applies to many video services across the web - trying to force the DRM hand too early will just perpetuate Flash.

    • The OS plays gatekeeper? Oh - you're talking about Microsoft. It's going to be their job to ensure that I see nothing that I haven't paid for. Cool, I can go for that. Sounds great. Except - Microsoft can't even effectively protect their own software from being pirated routinely. So - good luck with that, let me know how it works out! Meanwhile, people like myself will continue to use out unix-like systems to do whatever we damned well please. Oh - maybe I won't be able to view the latest and greate
  • Once Google states no DRM in WebM, Microsoft will win the battle and get hollywood on their side by offering DRM in whatever they cook up. That's the only reason they're asking this question. Without DRM there is no Netflix in HTLM 5 and for that matter any number of video options that may exist because the xxIA's require it.

  • ... so whether or not it has DRM is unimportant.

  • Which current web standards require a license fee to implement?
    Which of the two video formats would require a license fee to implement?
    Which would be better suited for the web?

    Besides, why would MS have a say in interoperable web video formats when their next browser won't even work on a large portion of their users' systems? They have demonstrated being incapable of making even their own product interoperable with their other products.
    Microsoft's usage share is dropping every month and with far superior c

    A video decoder needs the raw video bytes in order to update a frame buffer for display on the graphics card. Therefore somewhere between receiving an encrypted stream of bytes and processing a raw stream of video bytes, the decryption needs to happen.

    In classical cryptography the objective is to protect a message that Alice sends to Bob from a man in the middle. However, with DRM, there is no man in the middle. To address this conundrum, a secure channel of communication between the provider and the consumer of a stream is setup such that the private key of the consumer is assembled from some unique hardware parameters. If the user knew the private key, then the secure channel would be broken.

    Hence the objective in DRM becomes an absurd exercise in obscuring the client private key. The entire "security" of the DRM process relies centrally on obscurity. The "obscure" part is exactly how the private client key is built and what methods and protocols of encryption are used.

    With open-source however, no protocol will be obscure and no method to assembly a client key will be obscure. Therefore it is impossible to implement DRM in open source, because the whole premise of DRM relies on implementation obscurity, and the whole premise of open-source relies in implementation transparency.

If money can't buy happiness, I guess you'll just have to rent it.
