Norwegian Broadcaster Evaluates BitTorrent Distribution Costs 175

FrostPaw writes "An experiment was conducted recently by Norwegian broadcasting company NRK involving the release of the series 'Nordkalotten 365' (a wildlife program) in a DRM free format using BitTorrent. One of the broadcasters has posted the approximate figures for the overall distribution costs, and discussed his reasons for doing so. Their estimated cost for using Amazon S3 to offer the files through HTTP/FTP/etc. come to approximately 41,000 NOK (about $8,000 US). However, when using the Amazon servers as the originating seed and utilizing BitTorrent, their total cost for distribution of the entire project, thanks to generous seeds, would amount to approximately 1,700 NOK. The post with the original figures is available only in Norwegian.

    Making other people do your work for free makes your own costs cheaper. Film at 11.

    In other words, why is this news? It's something that has been obvious about BitTorrent since day 1: if you can get/make your users use their own upload bandwidth, you won't need as much of your own, and in a cost model that means your costs are lower. Did this really require a study?

        I'm surprised this hasn't already taken off for TV. Here's why:

        1. Right now networks can only own one station per market. With HD they can in theory broadcast multiple streams on it, but only a few. With online distribution they could put out as much content as they would like.

        2. Right now anybody can record and redistribute the off-the-air content. So, DRM is trying to lock up the front door when the back door is already wide open.

        3. Right now due to inefficient distribution schemes shows only run in a local market, creating a huge demand for online content. Typically this content lacks commercials, and is ignored when calculating ratings even if it did.

        4. If a TV station made it EASY to download their shows with full commercials they'd take over the market overnight. The big networks could collaborate to make it easy to watch their shows just like watching TV. Who would mess around with nzb files and all that when you could just fire up your online "Tivo" and it has already downloaded everything you're interested in. The polished experience would give them 99% of the market all the time.

        5. Sure, in theory somebody could find some way to redistribute their content and strip out all the commercials, but the scale of this task except for a few shows would be hard to match with the level of polish that the networks could deliver. They would still own copyright so they would only need to deal with distributed bands of unpaid volunteers redistributing their work - if anybody tried to organize they could be dealt with in court. The court cases would be stronger since the networks could convine local governments that they are actually genuinely trying to get their content to everyone (right now some countries turn a blind eye to copyright violation since it enables their consumers to get access to TV they wouldn't ever see otherwise).

        It seems like the TV execs are missing a huge opportunity that they could just own without issue if they just stepped out and took advantage of it.
        • Of course, you can already watch TV on the internet as provided by the large networks. It's known as Hulu, and you can watch stuff for free (with some commercials) at places like this [fancast.com]. It's not as revolutionary as being able to download via bittorrent, but it's a step in the right direction. Adult Swim does their own thing though. They put new videos of shows on their web site every friday.
          • You don't have to go to Fancast, although they do have a pretty good selection. But most of the current content on television is already put out the day after it "airs" by all of the big four networks (CBS, ABC, NBC, Fox). Not all the shows are online yet, but a good number of the popular ones are. And if they aren't, there's always the Pirate Bay, or TVU Networks,...

            The big problem with Fancast right now is that you can't watch the content there at full screen size, you have to watch it in your browser.

          5. I would predict "adblock for media players" within a week. It wouldn't be that huge of a task to create big lists of where the commercials sit on specific shows, throw them up on a server and automate the process of dowloading them. Then the media player just skips past those two minutes. No quality loss -- no large scale (re)distribution needed.

          It would only take one diehard fan record the time signatures for an entire series.. And only one good hacker to open up fastforward across an entire DRM scheme.

            I don't think that would happen on a grand scale. Set-top boxes won't have that feature, and any that do have it will be sued into oblivion and excluded from distribution channels like the local walmart.

            You could do something like this today with DVRs, and yet it doesn't happen - for precisely these reasons.

            The TV execs don't need to keep EVERYBODY from skipping ads. If they get 95% of the public to watch the ads (or even 50%) they can make a fortune. Most people won't bother setting up all kinds of 3rd

          Bittorrent is indeed efficent as it scales far better than http or ftp. A better example than that in the article would be the following article that was recently posted on torrentfreak.

          http://torrentfreak.com/university-uses-utorrent-080306 [torrentfreak.com]Dutch University Uses BitTorrent to Update Workstations

          The worst case scenario is when every single users deems uploading to be too costly for their own good and therefore caps it to nothing. In that specific case, bittorrent basically have the same efficency as http or ftp, needing the same amount of dedicated servers and bandwidth. There would be a slight efficency loss due to protocol overhead, but that is minor when dealing with large files.

          In most cases however, the upload bandwidth of a peer will be less expensive than that of a dedicated seeder for the simple fact that the peer is idle otherwise, while the dedicated seeder is working at full capacity.

          Also, spreading out the distribution costs on the users lessens/removes the need to actually have to charge the users for that same distribution. Even if the users have to pay some/most of that money to the ISP instead, the simple fact is that removing the need for micro transactions is a huge benefit in itself.

    The BBC iPlayer doesn't use BitTorrent, but it does use a P2P technology for distributing the DRM encumbered download versions of their programmes. The whole thing wouldn't scale without it.

    If you're not putting DRM on, then vanilla BT seems a perfect and ready-made medium. The Beeb, however, sell their programmes around the world, so won't knowingly let unencumbered versions out into the wild.

    • I'm sure that there must be something in the iPlayer to track you so that when the TV licensing people around they know you're a violater. I can't prove it though.
      • Unlikely. If the film studios & record companies can't get hold of a subscriber's details without a court order then what chance does the BBC have.
      • You don't need a TV license to watch things on the iPlayer. The rules for needing a TV license are quite clear with respect to online content - you only need one if you are watching content that is streamed at the same time as it is broadcast. Programs do not appear on iPlayer until an hour or two until after they have been broadcast, and so this is never an issue (you do, however, need one if you watch the live sports streams from the BBC, which caught out a lot of businesses during Wimbledon last year).
      • Oh, I wasn't aware of the need for a tv licence to view iPlayer content.

        Luckily there is one for the house I'm in. Guess I better get a license when I move out. Seems daft to do so, since I haven't owned a tv for years, but there we are.
    • It scales just fine - that's why the flash version is the most popular way of viewing iplayer. Added to that that the P2P is kontiki, which is a horrid piece of crap that eats bandwidth even when you're not using the iplayer (and with many users on 1gb/month caps that has already led to some enormous bandwidth bills)... people with sense don't install the app.

      That's an interface problem - not a technical problem.

      You could probably write a bittorrent client as a flash applet. You press the big, shiny download button that covers half of your screen, and the flash applet connects to peers and starts to download, all with a pretty progress bar. Even my grandfather could figure that out (one of my grandmas can't even use a mouse, the other is paranoid and believes that "They" are spying on her if she use a computer, so she got rid of it).

      Or, you could let people download an exe file, that when clicked will automatically launch a simple bittorrent client that automatically opens the torrent file for Nordkalotten 365 and starts to download.

        And for those who claim that bitlet is bad because the user is less likely to seed back as much as they take. Having someone not seed back is mostly a problem when dealing with torrents where there aren't any dedicated seeders, in which case torrents eventually will go dead.

        For torrents with dedicated seeding like the one mentioned above, that simply isn't a problem. Sure, having peers provide as much as they take is advantageous, but it simply is not vital in that kind of environment. Tit for tat provides enough of an incentive for the peer to atleast provide bandwidth while downloading.
        • You could have the dedicated servers provide 100kB/sec to each user, with the speed raised by people seeding back.

          In the case of watching tv, you could have people seed while they're watching it (after downloading it).

      In the UK, cost of internet data consists of two parts: The cost of getting the data to your ISP, and the cost of getting the data from the ISP to your home, usually using bandwidth bought at wholesale prices from BT (British Telecom). The cost for the ISP to send data to your home is around £0.60 per Gigabyte, But the cost to get data from

        I agree in general with your point, but I think your calculations are being very generous. When you get content from the BBC, the cost of getting the data to your ISP is almost nothing because most ISPs have a caching arrangement with the BBC where they host the large pieces of BBC content for their customers and so incur no external bandwidth charges. I contrast, Bittorrent does not take network topology into account, so you may well be exchanging data with peers in the USA. Since transatlantic bandwidt
        • If bittorrent will be heavily used to distribute mainstream media, the ISP's can cull cost without any caching arrangement. Just whitelist a number of torrent seeders (Mainstream, 'legit' seeders) at the ISP side, and cache/seed whatever your customers are downloading from those places. As you can provide best speed to the customers, they will mostly use your seeder and the traffic stays at home. This would probably be more flexible and powerful than current methods.

    At some level this is redundant, but I'm going to state it in a slightly different way.

    Of course distributing via BitTorrent is cheaper for the originator, nobody could possibly argue this. But I'd like to see a study on the TOTAL cost to society. In other words, yes it's cheaper for the originator, but there is no such thing as a free lunch. SOMEBODY is paying for all that bandwidth/etc. If you have bandwidth limits, perhaps you are paying for them to distribute their file. If you don't (as we in the US do not) then the telecommunications company is paying. Bandwidth does not materialize out of thin air. SOMEBODY pays. Further, BitTorrent is not exactly efficient. It uses a lot more requests/connections/etc to download or distribute via BT than it does via HTTP/FTP/etc.

    The offsetting factor may be the more distributed load over the system, since there's no central point, really. I'm not sure how much this really helps though.

    I guess my point is, the total cost to society of BitTorrent use may very well be higher than that for distributing by older methods.

      It make sense that the viewer should contribute some bandwidth.
    • I imagine most consumer upload capacity is sitting unused. Of course the ISP pays for its external traffic, but a lot of P2P traffic can stay within one ISP and therefore save those external links.

      The overhead is relativly minor when dealing with larger files. It is still the best argument. Minimizing the overhead needs to be a goal of an efficent p2p protocol.

      SOMEBODY is paying for all that bandwidth/etc.

      Yup. However, if any peers deems that paying for the bandwidth isn't worth it, they should turn off their sharing and get everything from the seeders. It will take longer since the distributor is spending less on bandwidth, but eventually he will get it.

      I can only HOPE that telecos have to pay a LOT of money. It's their stubborn refusal to enable multicast over their internet pipes that has made streaming video/audio and other large file distribution so incredibly expensive in the first place. If not for that, cable and satellite would have died off a decade ago, as IPTV would have been cheaper, and much more

    Multicast is so obviously the best solution all round for the, what, at least 50% of a national TV station's audience that watch predictable and consistent shows week after week. It would be pretty trivial for PCs to grab a multicast overnight.

    By the way, the BBC really tried to do this right [bbc.co.uk], but ISPs were too stupid to see that it was in their best interests to cooperate. This is my reading of the evidence - I accept corrections.

    It's certainly cheaper for the central server, but doesn't it just push the workload out to the local machines and network connections? Doesn't it just push the costs to the local user who pays for the bandwidth? I like P2P and think some of the algorithms are pretty clever, but I can't deny that my local pipe is saturated by the kids downloading things. There are times I would like my email and web traffic to move a bit faster.

    My prediction is that some clever Slashdot folks will start claiming that P2P is just an evil trick by the man to stick us with the distribution costs!

      Which is a good thing. Distributing workload to computers that would be idleing otherwise is efficent. Not to mention, that whole thing scales well so that the distributor can deal with a slashdot effect.

      There are times I would like my email and web traffic to move a bit faster.

      Use local traffic shaping software (like cfos) to shape protocols. ISPs however should stay with shaping the bandwidth per user as their agreement with their users shouldn't be concerning specific traffic. They are internet service providers, not world wide web service providers.

      • Which is a good thing. Distributing workload to computers that would be idleing otherwise is efficent. Not to mention, that whole thing scales well so that the distributor can deal with a slashdot effect.

        You are not distributing workload to computers. You are distributing the transport of data, and that is most likely not a good thing.

        Different pipes have different costs. The pipe that goes from your home to the ISP and back is the most expensive one you can find. A national broadcaster has a much bigger and more cost-effective pipe available. When the BBC started transmitting programs through the internet, ISPs were not much interested in caching the content, because the delivery from BBC to the ISP ha

    Rather than the broadcaster paying, because retail ISPs have significantly higher cost for bandwidth, this just shifted the cost from the broadcaster to the ISPs.

    For a one-off experiment like this, it wasn't a problem. But if you are an ISP dealing with a company like Vuse, who's businsess model is shifting terabytes in this way, it will be a problems.

    One of the broadcasters has posted the approximate figures for the overall distribution costs,...

    No, they didn't. P2P pushes some of the distribution cost from the originator into the network, and I don't see that this is accounted for at all. If things like Oprah-Skype [disruptivetelephony.com] at 242 Gbps become common, it will not be possible to ignore the distributed network costs.
