How Much Data Plan Bandwidth Is Wasted By DRM?
T-Mobile may not have great coverage — on our way to the Olympic National Park, my T-Mobile phone stopped working a long time before my friend's Verizon phone did — but I switched two weeks ago because the $80/month plan came with unlimited data, and I thought it would be convenient to watch Netflix streaming content and queued shows on Hulu from anywhere in the city. Since then I've been using data at about 10 times the rate that I did when I was capped at 2GB/month on Verizon.
But there was never any good reason that any of that data had to be downloaded over my data plan at all. I always know in advance what I'm going to be watching on Hulu, and almost always what I'm going to be watching on Netflix, which means if the apps would let me, I would rather download and queue up those movies and shows over my home broadband connection, and then watch the locally saved copies on the go. Hulu and Netflix would make at least the same profit off of me as they do now — I would still be watching Hulu's mandated advertisements before each show, and I would still be paying my monthly Netflix subscription. The difference is that I wouldn't be wasting a limited resource by downloading the content over my data plan. Even if my plan comes with unlimited data, that's not without costs, since one of the reasons I had to upgrade to unlimited data (and give up the broader Verizon coverage in the process) is that I can't download this content in advance at home. Otherwise, Verizon's sub-2GB data cap would have been fine with me.
Unfortunately, Hulu and Netflix apps both make it impossible to save their content locally, presumably due to a misguided attempt at DRM. ("DRM" is often used to refer to static content which has been encrypted in a way to make it difficult to copy; I'm using it more broadly here to include the practice of streaming content in a way which makes it difficult for users to save the content to a local file.)
(It has been pointed out, for example by Timothy Geigner on Techdirt, that data plan bandwidth may not truly be a "scarce resource" at all, and providers impose the data caps just to extract more money from users. The irony, though, is that even if the "scarcity" of cell phone plan data is not real, the streaming of content still constitutes waste of a precious resource, because users waste resources dealing with the data cap — prioritizing which content to download, or figuring out how to download the content illegally at home so they can save it as a local file. Or, they may simply decide to go without having the content on the go because they don't have enough data on their data plan — this counts as a deadweight economic loss caused by the DRM as well.)
You might think that the apps do not allow locally saved copies because the copyright owners prohibit it, but the Google Play app, for example, does allow you to download a saved copy of any content that you have rented or purchased from the Google Play store. (If you "rent" a movie or TV show episode from the Google Play store, you can still save it locally, but some predetermined time after you start watching the content, the content will "expire" and the file will be deleted.) So there is precedent for a non-fly-by-night company allowing you to save a local copy of content that you have paid for the right to access. So why not Hulu and Netflix?
I fear it may be that either the copyright holders, or the lawyers at Hulu and Netflix themselves, have been led to believe that locally saved content is easier to pirate, and neither of them want to be pegged as responsible for enabling piracy. This is fallacious for a couple of reasons: (a) If it's that easy, why hasn't it happened on a large scale with movies from Google Play, which can be saved locally? (b) Streaming content is just as easy to pirate, by, as a last resort, holding up a video camera to a screen playing the movie. (Yes, most users would not bother, but for piracy to occur, only one user in the entire world has to go to the trouble of doing this, and once it's done, an unprotected copy will be freely available on peer-to-peer networks for as long as people have any interest in the movie at all.) Which leads to: (c) Any user technically savvy enough to figure out how to pirate streamed content, is obviously going to be savvy enough to simply download the same content from p2p networks. In other words, forcing users to stream content instead of watching it from locally saved copies, gains the copyright holders and the app makers exactly nothing.
If I had to save content locally in the Hulu app before watching it, of course I'd have to watch ads before the content started playing, just as I do with the streaming version. In that scenario, if I had the time, I could probably try to find a black-market application that would watch the saved content without the ads, but like probably 90% of users, I probably wouldn't bother. And if I did want to make the effort, I'd just BitTorrent a copy of the movie or TV show instead, instead of trying to defeat copy protection on the local saved file.
I have no idea how much data plan bandwidth is used every day on content that users would have preferred downloading at home in advance, but it seems like a non-trivial percentage. Most Hulu and Netflix viewing is of movies or TV shows that you knew in advance you would want to watch, and could have saved. On the other hand, this wouldn't be true of random browsing of YouTube videos in the kind of mindset where you just watch a 60-second clip, feel mildly amused, and watch whatever comes up next in the recommendations bar to the right. Ironically, as you read these words, multiple telecommunications companies are drawing up plans to roll out billions of dollars' worth of communications infrastructure to provide more data services to more users — meanwhile, we could vastly increase the utility of the existing infrastructure with just the flick of a switch. (Well, a couple of switches -- convincing the copyright holders, and the Netflix and Hulu legal departments, that locally saved content is not illegal, as Google Play has shown, and could in fact make them more money. Hulu, after all, is making more money off of me now than the used to, since I'm watching more of their shows on the road, and viewing more of their ads.)
With a static download model, I'm sure the overwhelming majority of Hulu and Netflix users would go on paying (and Hulu would probably actually make more money, from the increased ad views). I would even start the day the same way, before even getting out of bed — by taking the phone on the bedside table, loading up a queued Hulu show, and getting the ad out of the way, then pausing just as the real show begins so that later on I can start watching it immediately. Because it just feels good to start the day with a feeling of accomplishment.
DRM is optional. Always.
I don't see a penny of that money either.
Without DRM, the Internet providers could proxy more popular streams, quite reducing the backbone traffic.
Yes, downloading videos in advance over a wired or local wireless network does save you precious mobile bandwidth when you view the content later.
But, streaming is easy. The consumer does not have to pre-decide what they want to watch if they stream. They're not sure if they want to watch a TED talk or the final Colbert Report while "roaming".
With Google Play, I can "pin" a show on wifi and watch it later, assuming I want to watch it later. It's still DRM protected. The bandwidth savvy consumer would like to download more content and play it back at any time, but do those consumers even exist as the majority anymore?
Processing power for decryption may be up though. But might be assisted by onboard chips. And video processing is not exactly lightweight itself.
The steps involved in setting up a Netflix stream have been fairly well documented somewhere. Unfortunately, this doesn't give you enough information to actually decode the stream on unsupported devices but it will give you an idea of what's actually going on.
The question is who is doing whom? Is it Haselton sucking off Soulskill ? Is Soulskill sucking off Haselton? Or, are they sucking each other off?
He's talking about being able to shift the download to his unlimited transfer plan and download it once rather than streaming it repeatedly on a limited transfer wireless plan. The overhead of the actual DRM is small. The overhead caused in actual practice of forcing an active stream to happen for each viewing on each device can work out to be huge in some situations.
Damn you Bennett, another wall of text bullshit article that is both fucking obvious and tl;dr at the same time. Please stop posting this tripe.

Because instead of downloading it to my device and keeping it there, it insists that every time I use it it calls home to ask permission. Which means, AFAIK, I could not watch an Ultraviolet movie on a plane. It also means they get to collect information from me when I watch the movie ... which I'm sure they love, but I'm not doing. If I play a CD the producer of it doesn't get to know when or how many times, because it's none of their damned business.
I'm also not willing to sign up with every #*%^% studio in order for the privilege of downloading a movie. Which, right now, first you sign up with Ultraviolet, and then you need to personally register your copy with the film studio. Yeah, no, not happening.
Companies make their DRM crap onerous to use, less useful, and more expensive. The alternative is to either not consume the product at all, or to work around their DRM crap. Which, of course, through years of bribing politicians is as serious a crime as if I'd robbed a bank with a gun.
I have a sneaking suspicion that DRM costs consumers billions of dollars every year, all to protect the profits and business model of the content companies.
DRM has always been crap.
Lost at C:>. Found at C.
Oh, he's talking about the ability to pre-download. A reasonable estimate is probably somewhere in the region of 1GB/hour. It's always annoyed me that Netflix doesn't allow you to pre-download or even buffer on a local network. I often know I'm going to want to watch something in advance but sitll I have to put up with that stupid spinning circle. It would take the wind out of Verizon and Comcast's sails too. Heck, with a bittorrent like protocol, I could even be buffering for others locally. I'm no fan of DRM but it seems it's often being implemented in a dumb manner.
BH = Bennett Haselton
Maybe I should write an article about it?
And every time I see a card for Ultraviolet or Apple digital copies, I throw the crap in the garbage. Until the day I can go to 'insert distributor here' and download a clean copy of the original movie, I'd rather just use DVD rippers or torrents to get a digital copy of the movies I 'own'.
Bye!
He is complaining about getting large files (movies) sent to his viewing device (phone).
If only there were some way to pre-download those files.
Such as DVD's. And play them on a hand held DVD player. And DVD's do not count against your 3G data allowance for the month.
Another useless article by Bennett Haselton.
It's not the direct overhead of the DRM, it's the way the drm is structured forcing the user to do things less efficiently. If the drm system only allows streaming then you have to push the data over whatever network you have at the time and place you want to watch and if you want to watch it more than once you have to push the data multiple times.
Without drm you can just download it once on the most economical connection you have available.

Yes! Thank you! The lead-in sentence: "read on for the rest of Bennett's thoughts" is exactly what we need when BH's blog posts go up on /. Keep doing that, so we can ID these.
The DRM doesn't have to encrypt every bit to be effective.
if the audio track + a strip of the green color channel in the middle of the image were all that was encrypted, no one would want to watch it without those portions, but it would use a fraction of the time to decrypt.
Wouldn't it cost Hulu/Netflix more bandwidth to allow this (and therefore more money in infrastructure)? Many users are going to download movies and never watch them, causing them lost bandwidth and possibly lost ad revenue. With a streaming model if you decide you don't like the movie, you just stop streaming. If you had downloaded the movie, the bandwidth required to give you that part of the movie you didn't watch is "wasted".
Alternatively, often you can also download it (still just as quasi-legally, of course) from the original source. For instance, Whedon's new movie, that everyone was complaining about not being able to download. Guess what? I totally downloaded it. I paid 5 bucks to "rent" it, then I immediately went and ripped it from the stream to disk with one of those free browser plugins. Now I can watch it on the plane like I wanted to! And I even got to still give Whedon my 5 bucks (which I honestly wish I could do more often for shows I like, actually give money to the people who made the show. I have no desire to pay ridiculously too much money for the dvd box sets, and know that almost none of that money is actually going to get into the hands of anyone who had a direct part in the making of the thing.)
The servers for streaming video need to have good network connections because the buffers generally aren't very big.
For pre-downloads they could use servers with crappier network links because they're not latency sensitive. Heck, you could do bittorrent-style peer-to-peer sharing of encrypted movies from other subscribers (maybe make it optional and give subscribers a credit for how much they upload to others).
There are at least four variants of chunked video streaming already (strobe, smoothstreaming, mpegdash, hls), where each chunk is available in different bitrates, and you only download a few seconds of the movie you need. If the average viewcount is below 1.0, you actually save bandwidth over downloading the whole movie in the highest quality.
Since digital restrictions management is a way for other people to control our computing, even a small amount of overhead is unacceptable, since DRM itself is unacceptable.
These comments are my own and do not necessarily reflect the views or opinions of my employer or colleagues...
Background downloading seems like the answer to Netflix bandwidth woes. Just background download the users streaming queue to disk at a snail's pace, like 256k or 512k. Within a month most people would have their streaming queue local and could watch anything on it without any streaming needing to take place. Maybe even throw in some downloads based on predictions of what you might add in the future or the kinds of movies you are prone to ad-hoc streaming.
The only streaming that would need to happen would be ad-hoc choices and some of them might already be local (sort of like Tivo Suggestions).
For most people with high speed internet, a 256k background stream would hardly be a noticeable drag on their connection and I'm sure a big part of the whole bandwidth "issue" is peak demand -- everyone trying to stream between 5 PM and Midnight. A low-speed background download would be less of a problem.
Do content providers actually object to this, or is it just not implemented because the DRM isn't good enough? You can download most "rentals" for offline viewing.
I suppose the biggest obstacle is how many devices don't have any local storage, enough local storage or are mobile onto networks where you would likely never want to background download a lot of content.
You can download TV episodes and movies to your computer or Kindle with amazon Unbox and walk away untethered and watch them. It still uses DRM to lock the content to the device, but you only have to download it once.
I would have read this submission, but I'm already half way through a 3000 page Novel at home and I don't need another one.
How Much Data Plan Bandwidth Is Wasted By DRM?
I was at least expecting an answer to this with some details. Maybe 0.1% of total file size = drm?
After all, this is "news for nerds", not "blogs for boredom"
But nope, we get a blog from some guy called Bennett with no actual technical answers to his own questions.
Rabbit on, rabbit on at the expense of this community Bennett.
I'm not sure it has much to do with DRM. If the stream is protected by DRM it will still be protected if it's saved locally. Obviously streaming makes it harder but it's very possible and Netflix shows like House of Cards on thepiratebay show it is being done.
I think one of the reasons for the absence of the feature is simplicity. When people ask me how to get movies for free I always recommend bittorrent, but most think that is too cumbersome, they just want to pick a movie and click play. If Netflix was to add the option they'd have to use a more complicated UI. They'd have people calling up complaining "It's not working" when they run out of storage, a lot of the non technical people I know still think RAM and storage are the same thing. I'd guess that the majority of Netflix users are non technical, stream from home, and not enough would use the feature to justify the development costs and complicating the UI.

Why should we read on for Bennett's "thoughts"? He's a twit. Why do you guys keep posting this garbage? Someone teach him how to use a blog, since what he's got here isn't "news", it isn't "stuff that matters", it's "some guy writing badly about things he doesn't really think through".

in linux any screen grab program can capture streams if you 'trust' the third party repository that hosts the software that convinces netflix it's streaming to a windows machine -- as long as you are using the open source driver to your gpu/apu whatever. in windows the driver enters a secure mode so you get a pink screen instead of the video, at least on ati it does.

Just enough extra bandwidth to transmit the keys.

* BH articles use up bandwidth.

Not sure what shitty 'DRM' you're dealing with, but all the DRM crap I have I download at home and put on my device and then it just plays whenever I want it.
If you're too stupid (yes, Bennett Haselton is fucking stupid) to not know the difference between streaming services and others, its your own fucking fault.
For fucks sake, have you never used iTunes or anything like it? Works FINE without a network connection once the initial authorization is done and that includes pulling copies off the network share where I saved them too the first time I downloaded.
Bennett, you're a fucking moron in every way.

reply. It so elevates the level of discourse. Don't you agree?
but the Internet culture will never abandon piracy.
Not Internet culture as a whole, but "Second and Third world internet culture and their Scandinavian 'pirate party' enablers"
If you guys want good content, either pay for it, or make it yourself. We could have DRM free if it wasn't for .po, .ru, .hu, .ro, .fi, .se, .br, .th etc etc.
Until they get big enough and are sued by everyone suing Aereo, http://www.playlater.tv/ does what you're asking for.
Records Netflix and Hulu, adding information stating that your account was used to do the recording (so that if something shows up on P2P, you'll get implicated fairly quickly). For movies/shows my kids watch repeatedly, I've found it nicer to just save a copy on my NAS and then stream it to the TV via Plex. The kids know exactly how to do this and typically check Plex before going to Netflix.
who the f*** is bennet haselton and why does slashdot keep posting his opinion pieces?
You didn't read it, but that's forgivable considering this poster's windiness.
He's not really asking about how much bandwidth, but which bandwidth. Many people today have two ISPs:
1) a cord of some kind that goes into your house. This ISP's data is effectively unlimited, or if there's a cap, it's relatively high (a few hundred gigabytes per month).
2) a radio mostly used by handheld computers. This ISP's data is limited because everyone is using the same airwaves, and using even a single gigabyte in a month, might be considered extravagant and wasteful. But most importantly: it costs more per byte than the other ISP.
Customers of the second type of ISP use terminology like "data plan." Customers of the first ISP consider "data plan" to be funny talk. And yet many of us have a foot in both worlds.
The idea is that with conventional video files, you can download it whenever you want, using whatever ISP you want. If you want to watch the video on your handheld (e.g. while commuting on subway) then you copy it over wifi or even sneakernet to the handheld. On the other hand, with DRMed streams, you can only use the whatever ISP you're able to connect to at the time you play the media. Considering that the point of handhelds is that they're most useful when you're not at home, that typically means it's going to be your radio ISP, the more expensive one. With DRMed streams, there's no time-shifting (or "network-shifting"). With conventional files, there is. So one tech costs more than the others, independent of how many bytes are involved.

Thank you for expanding on this comment from a few days ago, or either of these from a couple of months back.
Also, congratulations on realising that the content companies aren't really providing a good service to us. Do as the rest of us do and stick to torrents until they do. the music industry has learned its lesson and is now selling DRM-free files, the movie industry will catch up eventually.
Is 1563649 a prime number?
Content makers didn't start trying to distribute content online till AFTER said TLD's above (and others) were already pirating stuff left and right.
Heck back in the Commodore and Atari days, most of the big pirate groups which became "scenester demo groups" were based out of Europe, not the US. Didn't you ever wonder why that was the case?
It's because Anglophones and Japanese are wiling to pay for IP/Content in ways that Germans, Swedes, Finns, Russians, Poles, etc etc are not.
Heck, some of those J2ME/cell phone/Android/Indie devs in Scandinavia were formed by Ex-pirates wanting to actually make money of their skills. Course they found out that their own people didn't want to pay, so they make their money off of Americans and turn a blind eye to the rest of the world stealing their stuff.
Guess where Mojang makes their money? The US, UK, and Canada. It's anglophones paying for the development of software that the rest of the planet steals....stop that.
Haven't you ever wondered why the Linux LUG scene is more active in Europe (seems every little pisscutter EU town has a LUG that meets in a bar). Because the EU is full of people who don't want to pay for software so the free as in beer means more to them than the free as in freedom. As long as people outside the Anglophone countries and Japan have the cheap attitude towards software, software development in those countries will lag behind the US and the good coders from those countries will keep emigrating to the US.
Amazon and iTunes both allow DRM-laden *DOWNLOADED* movies. No, it's not "unlimited watch for a monthly price," but it's not DRM's fault. You're picking a completely different delivery mechanism.
Another non-functioning site was "uncertainty.microsoft.com."
The purpose of that site was not known.
Answer: NONE. A downloaded video from iTunes will be about the same size as the file you get when you rip a dvd or bluray disc. You can pick comparable dimensions, codecs, and bitrates and you'll pretty much get the same picture and sound quality.
Now, if certain providers won't let you download content and make you stream it over and over, that's an issue, but the amount of data used by the DRM itself is not.
Dear Slashdot: next time you want to mess with the site, add a rich-text editor for comments.
Bennett Haselton is the new Roland Piquepaille. As if once wasn't enough.

"I have no idea how much data plan bandwidth is used every day on content that users would have preferred downloading at home in advance, but it seems like a non-trivial percentage."
You have no idea. So why the fuck are you wasting everyone's time?
You know, there's a technology, at least as old as IP networks, that's multicast. If you couple it with a nice lack of DRM, you can reduce the required bandwith.
Even if you could build a workable internet-wide multicast streaming solution it would still not reduce the bandwidth to your phone. The same number of packets come over the air to your device whether they are multicast or unicast. The benefits of unicast are in the network infrastructure not the transmitters or receivers and, so far, these benefits have not been seen to outweigh the disadvantages.
Less than Bennet Haselton's articles, that's for sure.
Confucius say, "Find worm in apple - bad. Find half a worm - worse."
No, the page I was thinking of was more a technical description of how the keys were retrieved and the source for the encrypted stream was found. More of a traffic analysis. Interesting if that's your kind of thing.
Back when I had a smart phone, I'd typically use between 1 and 2 % of my monthly data allocation on my phone. I'd use more on my tablet, because I'd got a keyboard for that.
