Limited-Use DVD Technology 643

ps_inkling writes: "Two companies are creating different techniques to make DVD discs unusable after a set period of time. SpectraDisc has a patent on a limited-play DVD technology; FlexPlay is currently developing limited play DVD technology. The SpectraDisc technique is to coat the DVD with a film, then wrap the DVD in an anaerobic package. The idea is to sell these 'play-once' DVD movies at a substantial discount to regular DVDs as a way to compete with pay-per-view or movie ticket outlets."

    Imagine the uses for it.

    In the every box of cheerios you get a copy of the Powerrangers movie that you can play 3 times before you have to buy another box.

    This would enable cheap short life DvD's to be given away to people. Perhaps a movie mag could put on it all the new previews they had at such a small cost. As much as i dont like the idea there are many uses for this technology.

    Also I could see some of those online places that will let you rent DvD's over the net use such a thing. They send it out and you get to watch it twice or three times and they save money buy not having to worry about postage. I kinda hope this works and kinda don't due to it could become the standard and evuantally you wont be able to buy movies anymore but be forced to rent them.

    So the point of my comment is this. Any technology when used can be either good or bad. This has the future of both. I imagine both uses would get used out of it.

    Watch once = rip once

    In other words, it only takes once to rip the DVD image to your harddrive. The *actual* disk is useless after this point.

    Did I mention that 120GB harddrives are very cheap right now??

    I will purchase these read-once disks if:
    (cost of read-once DVD) < (cost new DVD) - (Resale value of used DVD).
    It's simple mathematics.

    Ahh yes, another piece of junk for us to accumulate. I think I'll shelve the used discs on my bookcase, next to the handbook on "How to reduce clutter".

    Wouldn't it be nice for a change if our culture moved away from selling to people as much junk as they can buy? Disposable diapers, disposable cameras, disposable cellphones, etc. I find that many people lead just as disposable lives, unfortunately -- with the quality of life getting emptier as people get richer.

    Yes, yes, I know that all marketing is about making people want something they didn't know they needed before. Just because we're accustomed to it doesn't mean it's the right thing to do. I look forward to the day when we can overcome our material desires, the need to one-up our neighbors, and express our achievement through spending money.

    Maybe science, freedom of information, and education will get us there someday. I hope.

    Next question: if somebody develops a way to preserve these disks, will that be illegal?

    I suspect this is a non-starter of an idea. Polaroid developed a comparable technology for VHS caisettes in the 1980s, using a mechanical ratchet in the cartridge to limit the number of plays. That went nowhere.

    I'm assuming that this "film coating" is the same tech we heard about a while back that causes the DVD disc to corrode into uselessness shortly after the film is exposed to reader light ...

    Is anyone else worried that this film might "rub off" onto your DVD tray, and get onto one of your other discs afterward? I'd certainly be pissed to discover that the rental DVD I purchased destroyed the discs I already own... I don't think there's a conspiracy here, but I don't think this film is a good thing, either.

    To be honest, if I want to rent a DVD, I go to blockbuster, or Hollywood Video if there's one near by. It's cheap, it's pretty painless, and there's no risk of the disc destroying my setup

    One thing that is VERY nice about DVD rentals is that you can watch the movie one year or eight years after the video store acquired it, and -- provided the disc is readable -- you get the same experience ... digitally identical playback, every time, unlike VHS, which corroded and is useless after a few years.

    If the disk is rendered unreadable by a reaction involving oxegen, all that is needed to keep the DVD's from going bad is to store them in an oxygen free environment. After you open the packaging, watch the DVD, then place it in an airtight package with some yeast and water (the activated yeast will consume the oxygen in the container) and the disk should still be playable at a later time providing the new packaging is airtight, and you consume all the oxygen.

    Of course the other obvious way to get around this is to rip the contents and burn your own.

    I don't see what the big difference is between paying Blockbuster $4.95 for a limited time rental and purchasing a limited life time disc for about the same $$$... Oh, except I have to return the disc to Blockbuster or face late fees. Why exactly is this so bad?

    Also, imagine a day when you can walk into the Blockbuster and instead of seeing miles and miles of movies taking up valueable space, you can pick out the movie you want from a kiosk, with access to more movies than you could squeeze into acres of Blockbusters, and a DVD-R burns it for ya with the time limited coating... That makes sense to me.

    The best comparison to this technology is renting a DVD from your local Blockbuster. While I am not a big fan of Blockbuster, per se, I see absolutely *NO* advantages of this technology over renting at Blockbuster.

    At Blockbuster, I walk in, give my $4, and walk home with any movie on DVD. I can watch this movie any number of times in a certain time period. With these discs, I walk into Blockbuster, put down my $4, and walk out with a movie on DVD that I can watch any number of times in a certain amount of time.

    Why, then, would anyone get one of these?

    Well, I suppose you do not have to return these new movies, but is that a big enough incentive?

    If you charge $3.99 for one of these movies, I assume that Blockbuster is going to walk away with $2 per disk. That is a 100% return. On the other hand, if Blockbuster buys a new DVD for $20 and rents it 15 times at $4/rent, that is Blockbuster walking away with a 300% return on the investment.

    On top of that, Blockbuster still has the movie! They can continue to rent it out, or sell it as a previewed move for $10, making even more.

    No, this makes no sense for consumers or for the rental people.

    Wrong. Late fees, which frequently cost more than the original rental, are a major revenue stream for Blockbuster and other movie rental companies. They don't have any incentive to back this sort of technology.

    Just thinking about potential uses... if the coating can be applied in a fashion that the coating only erodes AFTER being hit by the read laser... corporations or other groups such as Amnesty Int. could issue all offices with a stack of DVD's - on each DVD put large (say 16MB) random data files (ideally generated from a true random source such as background radio noise or leaky diodes) then each time something really confidential needs sending use the correct disk and file - the act of reading the file will cause to be zapped... the only part of the disk that needs to be permanent is the directory structure.

    Is it just me or is this idea of woro (write once read once) abit Mission Impossibleish -- this DVD will self destruct in 1 day...

    There is another point about this, by having to return stuff to the shop I'll bet they get a reasonable number of additional rentals from impulse decisions while returning itemsf.. At least for those who do it during opening hours.

    On the other hand, if returns stop they can reduce staff counts, this may seve them more money than they loose..

    But they still have ways to get additional revenue streams to partially replace these. How about an environmental charge, similar to a deposit on glass bottles (common here in Europe). You pay extra 'up front' for the disk, but if you bring it back this gets refunded (CD's etc have a very small recyclable content/value, but since when have people in the entertainment biz. let the facts get in the way of profit?). This way they get extra money from the lazy and drag you back into the shop too..

    That's it i'm sealing the windows, borrowing my 79 year old grandmothers oxygen tank, and filling the room with helium.

    Would a room filled with helium improve the efficiency of my speakers? The lesser mass per volume would allow the speakers to push the air easier and quicker. I suppose this would lead to my sub being able to produce higher frequencies.

    Only down-sides to this would be that helium doesn't conduct sound as well as the higher density air does, and the frequencies that my speakers can produce would change which would throw off the balance between them.

    So how long before we get a sealed unit DVD player. Sound viable to me. Build in a 100 disk storage carousel, a loading system which doesn't expose the disk to air - it only has to open the wrapping on the disk - and away you go. Would you use an inert gas in the carousel/player or would you evacuate it ? Sounds like the geek water conversation of the future 'I use a 100 capacity argon carousel' disdainful look 'really ? I use an evacuated player for higher laser read performance and self locking, low pressure helium storage cases'. What would be better ? Vacuum ? Or do you need gas to cool the equipment ? Does the laser oxidise the new coating on the DVD ? What happens if you want to replay the part that you just saw ? If you need gas for cooling, which would be best ? Helium ? Argon ? Neon ? Nitrogen ? Xenon ? If you used vacuum could you drop the laser power ? Would it mean better focussing ? Higher data density ?

    There has to be some better use for this technology. Instead of looking at the rental space, maybe they should concentrate their efforts on using them as promotional materials or something else which can be given away for free to the end user.

    At least it's slightly better than DivX in that with DivX, you needed to purchase a special multihundred dollar player. DVD players are of course readily becoming a dime a dozen now.

    Man, far more than the usual number of knee-jerk reactions, this time :-)

    First of all, didn't Divx require you to buy a special Divx player? That's a big difference, investing in a new technology that *only* supports limited use.

    Second, regarding the waste factor: have you ever been to McDonald's? Or any fast food place? The amount of trash one gets is huge as compared to a single disc. (And the disc seems to start biodegrading anyway, the minute you open it :-) Have you ever subscribed to MSDN? You end up throwing out dozens of CD's a month (or a DVD or two a month now). And I've certainly created many times more coasters than the number of movies I've watched in my life.

    I'm not saying more waste is good, just that in perspective, this isn't a huge factor.

    This needs to be compared to rentals, not purchase. I've spent more money on Blockbuster's annoying but smart (for them) return policy; midnight the next day. It lulls you into a sense that if you don't get around to it tonight, you can watch it tomorrow, and return it before midnight; tomorrow night comes, you watch the movie, and are too tired to return it (I always :-). They spent a lot of time coming up with that policy. So I end up paying late fees on top of the not-so-cheap rental. I personally find returns horribly inconvenient. And the rental companies no doubt find them extra labour to process.

    The rental places could also have a better rate at movie availability. I would guess that they could predict the total number of rentals more easily than the daily rates. So they stock up, and you can be assurred the movie will be in. In fact, the day the movie is released, you stand a *greater* chance of being able to get it. That's when people most want it, too. That kind of works out well.

    The main disadvantages I see are 1) storage space required in the store will be greater; 2) there will be less older run movies available, since they don't stick around. If this takes off, six months after release, it may be very hard to get a copy of a movie. And, as mentioned, there will be some waste, although that can be played off a bit against gas, pollution, and labour in handling returns.

    I wonder if they could make them taste like chocoloate or nachos? $2 or $4 for a rental, that would be a nice tasty snack afterwards would be very cool, and avoid the waste problem, too (well, at least modify the waste problem to an organic one :-) There'd also be something symbolic in becoming one with a movie you really liked, and even one that sucked and deserves no better fate than being eaten :-)

    Yes i do feel guilty about throwing away AOL and other CDs. Something feels wrong about taking a perfectly new, unscratched CD that could last for decades if looked after and binning it because of course its contents (AOL) are useless.

    Sadly, I think people will buy into it. Its main attraction is convinience, and we're so used to every convienince imaginable as consumers today. I think its a sad state of affairs if it does take off cos it proves we'd rather throw away brand new DVDs and add further to the huge amounts of waste that such conviences cause.

    It requires polycarbonate to make CDs and DVDs. Polycarbonate that's generally not recyclable or biodegradable. If the disc self-destructs, it's landfill fodder- which means they're going to be choking up the world with nigh worthless plastic discs, using precious resources (the plastic, the materials to make the disc, etc.). All of this to make that precious pay per view they've been seeking all these years realistic and to do away with rentals (Realize that the media companies view rental companies as the enemy (except Viacom- they own one of the largest rental companies out there...) because they don't control the situation themselves. Rather than fostering their own rental company as Viacom did, they'd do this instead...)

    I know for a fact that SpectraDisc is using a sort of a "freshness" limitation.. to where a disc is fully readable once you take it out of a sealed package, but after a specific amount of time it spoils so it is no longer readable. There are no intelligent actions going on, it just fades out. According to their press release, the amount of time can be controlled between minutes or as long as weeks before the disc is unreadable.

    Personally, the first thing I thought of when I read the summary was buying some of them for cheaper than "standard" dvd's, then ripping them.
    It'd be even more amusing if someone figured out the chemical composition of them, then figured out what to do to make them not fade away.

    I can't comment on Flexplay's technology, since they don't even have a webpage up yet.

    If I bought a Divx disc at the store, at least there was some opportunity to permanently purchase the disc. In this situation, I buy a disc, and it becomes useless. If I happen to really like the movie, then I have to go and buy it again.

    With the advent of Ebay I can't fathom why any of these companies are even bothering. I can go to Amazon and order a brand new DVD, or perhaps even pick up an early used edition at Ebay. If I don't like it, then I just put it out on ebay and offload it to somebody else.
