The Future of Digital Video?

An Anonymous Coward, in name only asks: "I've been asked to write about the Future of DVD technology for a newsletter and I've been doing some thinking and research regarding this. It seems pretty clear that DVD is a dead-end technology, due to be replaced by Video On Demand. Already Disney is launching a VOD service, albeit through traditional broadcasting. It's to be a brief piece, and I plan to touch on how VOD will affect viewers as well as professionals. What is a realistic timeframe for beefing up broadband (such as Powerline Broadband?) and smartening compression (On2's VP5 , MPEG7?) to create a workable VOD system that will replace DVDs? Is delivery more likely to be based on an open or proprietary standard? What do you see as the future of Digital Video? Any input is greatly appreciated." While I don't think that Video on Demand will spell the end of DVDs, it would be interesting to know how far the technology has progressed, and how much further it would need to be developed before you could can pick-and-choose your movie-of-the-night from your own living room.

It's much the same reason getting music by buying MP3's (say from apple's new service) will not fly in the end. People want to have the CD, a real cd, not a burnt copy.

      As a corporation, they're pretty greedy and paranoid, but the fact is that people will buy Disney DVDs even if they own the VHS tape of the exactly the same movie.

      Later, when HDTV's start becoming really popular (i.e., when their price dips below about $1000) and we all gripe about crummy 480p output from the back of the old DVD player, a new, higher resolution format will become available, and people will flock to stores, snapping up copies of Snow White for a third time.

      As long as the price of the media isn't too high and as long as most houses don't have bidirectional high bandwidth connections, this business model will keep them and other movie producers in cash for years to come (but not decades).

    It seems pretty clear? I hardly think so (at least not with the traditional definitions of video on demand). People want content they can keep around as long as they want, whether it be a VideoTape/DVD they purchase, or a TiVo recording they keep on their unit for months. Even Netflicks lets you keep the DVD for as long as you want before sending it on to the next person.

    The era of video rental stores demanding a return within 48 hours will eventually end. If given a choice, I don't think anyone will choose another system where they have to hurry-up-and-watch something, even if it's video that they ordered whenever they ordered it.

    Look at Apple's recent music offering. People can purchase music and keep it as long as they want. Whether you like the idea or not (and whether you plan on buying music that way or not), it's a sign that we won't be limited in our purchasing options to such restrictive pay-per-view watch-it-now methods.

    DVD's will be around a while, and when they're gone the replacement will be something more akin to a permanent download into a huge video jukebox appliance than some watch-it-once-and-never-see-it-again model.

    The VOD is in a way very similar to the previous DVD standard called DIVX where you'd "buy" a movie but after you started watching it you had to finish watching it within 24 hours and after that it was locked up. The DIVX players had to be connected to the phone line for that very reason.

    And DIVX disappeared. Although I believe that he is right in saying that VOD will be very important in the years to come I believe DVD (or some HDTV successor) will continue to thrive too.

    Depending on the intelligence and power of the set-top box. Historically, controls such as pause, fast-forward etc. involved the set-top box having to communicate with the server. People get annoyed very quickly when they hit pause and the video stops three seconds later. Latency is a serious pain. Clever programming can alleviate a lot of the problems, but it's just another thing that makes VoD inferior to DVDs. This killed most/all the pilots I saw several years ago.

    If I decide half way through a DVD that I'm too tired, or something comes up, I can power off the player and come back the following night and carry on as though nothing had happened. I don't believe VoD offers this kind of flexibility. If the content providers could truly supply a huge library of video, fix the latency issues, charge a decent (low) price, provide the needed flexibility etc. etc., then maybe VoD has potential.

    VOD is pay per view. Convenient, but...it means paying each time you watch the movie. Purchasing a DVD means it's on your shelf so you can watch it (and all the extras) as much as you want; very convenient if you have kids who want to watch a favorite film twelve times.

    Folks like to collect, they like the extras, and they like the convenience of having it on their own shelves. VOD, like pay-per-view, lets someone else keep tabs on your buying/renting habits.

    Look at why DVD's are popular:

    - No degradation through normal viewing.
    You can watch your DVD as many times as you want and it will look the same every time. They are however less damage resistant in that 1 deep scratch in the right spot will turn the disc into a beer coaster.

    - Near-instant access
    You can fast forward or rewind to almost any point in the feature with the flick of a finger. With on-demand tech, this may never be an option. One of the biggest complaints with VHS were that you had to rewind them, and this took a long time. As did fast forwarding(or slow, I should say). Finding a particular scene took quite a while with VHS. Try doing this over a latency ridden network! It wont work. I don't think my cable company is going to install multiple, seperate gigabit networks for each neighborhood or street. If they did, I'm afraid of what I'd have to pay for it. Bandwidth costs. The cost structure to support it would be unfavorable to most consumers.

    A high percentage of the cost of a DVD is the content, bonus content, profit, and packaging. The DVD disc itself is a small percentage of the cost of a DVD. If an on-demand service let you buy rights to view an on-demand movie whenever you want, however often you wanted, there would be continual costs incurred as well as initial investment. Even if I only pay $5 to buy a movie the first time, I won't pay another dime to watch it again. The recurring costs for the cable company to let you watch a movie again and again for free is unprofitable.

    I'm not saying Video-on-Demand is built to fail. It can work in the same capacity that Pay-per-view does. The infrastructure required to suport VoD will not be put into place until either it comes over the preexisting copper or wide adoptance will make it profitable.

    In short, VoD must provide the same features as a DVD at a lower cost before most consumers will consider it over actually purchasing a DVD. There are also those who, given both options, would choose the DVD every time.

    Video on demand won't replace DVDs for the same reason that proprietary (and possibly all) e-books won't replace regular books.

    In a similar way in which a regular book gives me the security of knowing that I don't have to worry if the company that published it goes belly up, if I buy the DVD, I own it (for my own use, of course). I can watch it when I want. I can watch it on an airplane, I can take it with me on business trips overseas. It's going to be a long, long time before everyone in coach can watch "on demand" flicks on an airplane.

    When you have a DVD, you're not dependent on the whim of a company. Consider shows like The Family Guy or Futurama where Fox never gave them a fair chance, then pulled the plug. They treated these shows like shit the first time; what possible reason do I have to believe that they're be treated any better "on demand?"

    What about British shows like I'm Alan Partridge, Good Neighbors, or Father Ted? At best, I can watch them on BBC America or PBS, but unless I buy the DVD (or VHS, or whatever comes next), what are the chances that I *know* I'll be able to see these shows, when I want, here in the USA?

    Then there's the content itself. What happens when the company that owns the rights to these shows goes out of business? What happens if a bunch of Jeezoids decided to buy the rights to something just to kill it (for the chillllldren, of course)? Or what if they just decide that something is insensitive and cut it. Jesus, what if they alter the original: Colorizing it or adding those fucking "informational" popups like they do when they show Double Indemnity on the Lifetime network?

    What happens when some soulless bean counter decides that since I'm the only one who wants to watch Seriously Dude, Where's My Car?, they should just save the server space and dump it? You already see this sort of thing in video stores, when they decide how many foreign films can fit in that little section. The Internet Movie Database lists 268,836 movies released theatrically, 35,200 made-for-TV movies, 23,625, TV series, 21,420 direct-to-video movies, and 3,081 mini series. How many of these are going to make the cut? Which do you think will come first, some of those films, or "on demand" sports, so folks can have "Classic Games of when the Red Sox blew the World Series" nights?

    Finally, why should I keep paying for the content through a subscription or a download fee each time? Compare the price of DVDs with rentals and pay-per-view -- if I think I might watch it three times in the rest of my life (or I might want to loan it to a friend) why not buy it outright for the extra ten bucks?

    1080i and 480i are measures of the vertical resolution of the signal. VHS is also 480i, though it isn't digital and the horizontal resolution is nowhere near as good as DVD.

    Horizontal resolution is traditionally measured in lines per picture height (not width), so that the horizontal and vertical resolutions have the same scale. (Note that film resolution is normally measured in "line pairs", but video resolution is not.)

    A DVD normally has 720 pixels horizontal by 480 vertical (interlaced). If it is mastered with Academy Ratio (4:3) video, that means it has 720 * 3/4 = 540 lines of horizontal resolution. By comparison, VHS has about 240 lines of horizontal resolution. Note that the horizontal resolution is different for anamorphic widescreen DVDs when played on suitable equipment, because of the different aspect ratio.

    HDTV at 1080i has 1920 pixels horizontally, and 16:9 ratio, so it has 1920 * 9/16 = 1080 lines of horizontal resolution. Since the horizontal and vertical resolution are the same, the pixels are square, unlike most video formats.

    * Access "anonymously" (atleast the store owner does not know your perverted viewing habits, which I must mention I do not have!)

    * Its collectible. I have two 300 DVD players stacked with DVDs I've purchased over the last 4 years for the simple reason that I love movies and want to keep them around for a bit.

    * Progressive SCAN + DTS / Dolby 6.1
    * Amazing data transfer rates
    * Rentals are getting cheaper. In the US you can rent using Netflix (quasi anonymous again)

Sometimes they want liner notes, documentaries on the production process, a poster for their wall, or simply a physical presence so their small pre-literate child can let them know WHICH movie or show they want to watch with a minimum of whining.

Sitting at a computer browsing through a catalog simply doesn't provide the same experience.

    And yes, go ahead and ask Blockbuster how adamant people are about keeping their own discs. Haven't you noticed the new "get a discount when you buy a movie you've rented" program? I'd say they're trying to capitalize on the people like me, who rent a movie solely to find out if they like it enough to buy it, and then buy it somewhere cheaper! However, there's currently no way to tell which people purchase for economic reasons (it's cheaper to buy than to rent over and over) or hard copy reasons (simply liking to own a physical copy). The people who buy for economic reasons would probably love VOD if it was a purchase, rather than a rental scheme.
