    Didn't we hear about interactive TV before? Isn't that garbage over? Granted, TiVo is fairly popular, and it deserves it, but everyone I know wants to sit in front of their TV and be a vegetable. That's what it's good at, and that's what people use it for. This one'll sink because people would rather be lazy.
    • This one'll sink because people would rather be lazy.
      Interactive TV is in its infancy at the moment, and (here in Europe at least) the various stations are still vying for the Most Inane Use of the Red Button on a Sky Remote award (my nomination: vote for the brainiest contender on Discovery Mastermind). And, as you said, people are lazy. However, I suspect this will be a much-used aspect of future TV watching (or 'participating', as our chums in the media will doubtless prefer).

      Imagine for a moment that you're a normal muggle. Someone tells you that one of the cast of Friends has a new celeb boyfriend. You turn on the TV, type in the name of that woman who was on The Misfits of Science, and voila! You need never read a proper news story again.

        Why not the computer then? The TV limits what people can do necessarily. I can't really imagine anyone wanting a keyboard for their TV any more than I can imagine someone buying one for their gamecube. Note that these peripherals don't sell well on systems like video game consoles that are inherently interactive. There's no way someone is going to use one on a machine that is naturally the exact opposite of interactive.

        Producers have spent decades making TV the exact opposite of interactive, and they've done an admirable job of it. I know of no better way to kill your mind than TV, even drugs don't do the job as well or as easily. Then they tried to take this philosophy to the internet with Push technology. Remember when that was the thing? How often do you hear about those guys now? The same way push failed for the internet, interactive TV will fail because it's the antithesis of what people know and love about television. It's not a bad idea, it's just not going to work

          All this assumes the internet as it is now, of course. For always-on users with speedy access, the computer is as easy. But for the drooling masses television is the first port of call, and if it's available on TV it's not needed elsewhere.

          Also: in the above example, a lengthy search wouldn't be necessary. Interactive->Entertainment->Hot Love Story. Three presses.

          • That is an excellent point, that people are too lazy to go to the computer and would just stick to the TV. But I think that no one is going to pay for a service like this because it's more limiting than the computer. AOL makes things pretty easy for most people, and provides things like email and the ability for your kid to run Morphius. TV doesn't do that, although they've tried. WebTV was easy as hell, but it's gone exactly nowhere. People are used to the computer, and it's easy enough for them.
    • A few years ago during the web boom (remember that? It was like the CB craze of '77), Veritas was making the same claim.

      They had Clinton's "Monica" testimony indexed so you can search for words (think "cigar") and get to the portion of the video that mentions the words.

      Since most television is closed-captions these days, it's not hard to get searchable text that corresponds to video, once the video is put on some random-access storage medium.

      I really don't think there are any new breakthroughs here; it's just that storage got dirt cheap, video codecs got faster, making it more practical.

    Since the advent of the Web, I find myself wishing more and more physical media was indexed and searchable.

    Ever read "Fellowship of the Ring" and wish you could search the book you're holding? Or watched a bunch of shows end wish you could grep for something you remembered hearing?

    As the TV/Computer/Film merge and become more dense we need better ways to pick out pertinent information 'nuggets'. Otherwise, it is just information overload.

    • Sure we all say this sounds great, those who are on topic, but are we really going to allow something so powerful and some what useful become real. The net grew from the computer as a need of sorts. Are we going to allow our behaviour to change for a searchable TV instead of develop?

      The internet has put more computers in homes than Microsoft could ever take credit for, but the TV has been there far to long. As they say, you can't teach an old dog new tricks. It would end being a high priced electronic toy used rarely day to day, a nitch market at best. Just like other "web enabled" appliances. Such a shame.

    • Actually, now you can search Fellowship of the Ring. You just have to download an illicit copy via Morpheus or Gnutella or whatever. :)

      Ever read "Fellowship of the Ring" and wish you could search the book you're holding?

      Yea, all the time, and so I eventually came out with a truely ingenious way to do this for non-interactive print media. First we go through all the words in the book and find out what pages they appear on then make a list of these words with their corresponding pages. Of course some words (like "the") appear to often so should be dropped from the list. What your left with is a list of the words most likely to be searched for (names, locations, times, etc.) and where they appear.

      Next - this is really ingenius - we arrange these words in an arbitrary order that is the same for all books. Unfortunately we would have to force everyone to learn this order. I was thinking we should make it really confusing just because we can, like say a vowel followed by three consonants, then another vowel, and so on .... for example: A B C D E F ..... Personally I think this isn't asking too much of people.

      Then we take this index and include it in some convient place in the book. Say, at the back. We could even call it "the index". It's so simple, yet so powerful, I wonder why nobody has ever thought of this before. Hey, I should patent this idea ....

      • Yeah?

        And when is the last time you read a Tolkein book with an index in the back?

        Works great for the Perl Cookbook.... but, non-fiction doesn't tend to use indexing too much.

        [pretty funny post though!]

      hmm. I don't think the resources are 'unimaginable', just ridiculously, ridiculously big. A (really) rough back of the envelope type of calculation on what storage resources might be required:

      - Let's say a DVD holds 8 hours of acceptable quality video.
      - this translates to 15.9 gigs I think? (someone please correct me on the specs if incorrect, I don't even own a DVD player)(what the heck, it'll only be an order of magnitude error or so)
      - TV is what, 75 years old [uwaterloo.ca]?
      - Assume there have been 1000 channels in the history of tv, even though there are doubtless more now, but obviously less in 1950.

      So 3 DVDs or 48gigs = 1 day of storage for 1 channel.

      48gigs* 365 * 75 * 1000
      = (hmm, where's that calculator)

      1,314,000,000 gigs
      =1314000 terabytes
      =1314 petabytes
      =1.3 exabytes

      (I think. Ahem. Please correct any gross errors in translation/calculation. Don't ask me to land the Mars Observer.)

      For comparison, George Gilder notes [lotus.com] that a study showed that the total traffic for the Net was about 1 petabyte a month. (I know, the real figure for comparison would be, 'how many terabytes does the Net contain?' I don't have time for that search! Anyone?)

      Terabyte servers are in use now; it's within the realm of possibility to imagine a million of them. Chuck in the hard drive equivalent of Moore's Law, a breakthrough in holographic techniques, ("Windows 2010 requires a minimum of 1 terabyte of hard disk space...") and hey, you could maybe make some half-assed attempts at this 10 years down the road.

      Of course that's just the storage calculation. I've ignored the gross problems of:
      -digitizing all the historical stuff on tape
      -indexing it all with at least an IMDB-style header of metadata. Full text search would be nice too :-) (hey, a bonus from closed captioning)
      -providing adequate last-mile bandwidth so that 200 million americans can surf different tv programs simultaneously (trust George Gilder!)
      -the IP issues: how hollywood, the courts, and popular sentiment will interact to drive this thing forward.

      Unimaginable? Not necessarily. Permanently storing all TV produced would be difficult right now, but it wouldn't be impossible to store the last year's programming using today's technology. Assume that you capture the video at 5Mbps MPEG-II:

      Some quick calculations, that's 54 GB of data per day per channel. Sounds like a lot, but you have to realize that such an application can be massively distributed. A single machine with 10 (70-100GB) drives could hold a couple of weeks worth of a single channel.

      Multiply that by the actual number of broadcast channels out there generating "new" content (channels that simply rebroadcast movies and older recordings need not be archived in full, and your PPV and Music channels hardly count), a year's worth of programming could be distributed across a thousand machines scattered across the net.

      That's using today's storage technology, which is increasing dramatically in capacity. The advent of HDTV will set things back, but that's a one-time hit. I would imagine that within the next decade and a half we'll be seeing systems designed to do exactly what we're talking about here. The major obstacle is not the technology, it's reticence from the broadcasters who own the content.

      To do that, the box could request a copy of the currently displayed frame from a server, every time you change the channel. This would require two-way communication (possible on a cable network), and might be a privacy concern (the server would know what channels you're watching - although I hear digital cable boxes already send that info), but would probably give you an image within 50 ms. Another way would be to constantly transmit low-quality/low-resolution images (probably 10-15 per second, compressed using a lossy codec). You'd at least have some picture as soon as you change the channel, and you'd have full quality video as soon as the next keyframe is received (within a second). According to an earlier Slashdot article, digital channels aren't using all their assigned bandwidth anyway.

      Second part: I want a device that eliminates the stupid and annoying station logos. Contrary to popular belief, many people actually know what damn channel they are watching

      I recently used a digital cable box at someone's house. When changing channels, it displayed the channel number, channel name, and (on some channels) the name of the current show. This makes the watermark pretty pointless. If a digital TV company was using one of the methods I mentioned above, they could transmit a watermark image as well. The box could provide an option allowing you to show the watermark always, never, or for the first few seconds after tuning in (after which point it would fade out).

    • I want Satelite or digital cable that changes channels as fast as conventional cable (meaning *instantly*).

      I timed my digital cable from COX. It takes over a second to change channels, and it won't let you switch channels for that time. This is even with the lower analog channels. And I have two different types of receivers that act the same way. Somebody should pull Mr. Cox (or whoever is the CEO) out of his car and savagely beat him! I cannot flip channels anymore, so it totally changes my viewing habits. But getting digital cable is the only way of getting HBO, Cinemax, etc.

      Of course, COX is evil anyways. They kept playing commercials saying how stealing cable is stealing from the community (presumably because they give all their profits to the community or something (yeah right!)). And they made a website so you can report your friends who steal cable. Sure, I understand why they want to FUD everybody into buying cable from them, but sheesh!, this tactic sounds too much like the informant system in communist Russia. When I move in a few months, I vow never to buy any kind of service from COX ever again!

      And I have seen the direct tv and other satellite systems. They are much snappier than cox digital cable (which totally sucks ass).

    So what are the long-term results of this service? Will it bring people to their TV looking for a documentary on Mesopotamia? No. It will bring them to look for more useless crap to zone out on. Just like the web gives you the ability to filter out opposing points of view and leave you in an stimulation vacuum of like minded people this tech will make TV a further black hole of non-information.

    As an experiment for all of you who have 100+ channels: unplug the cable/satellite for a week so that you are reduced to just your local stations. Notice that you will watch the same amount of TV, or even more, because you will continue to flip through the channels until you do find "something to watch".

    Save your self now and just unplug it. Life is much better when you do that. I just finished the Autobiography of Ben Franklin, which I would have never seen on TV. And because it takes considerably longer to read than it does to view you get the added benefit of absorbing far more.

    This stuff is being reported as a very novel stuff. But there has significant research being done in academia.

    Stony Brook (SUNY) ECSL [sunysb.edu] has developed a Videoserver prototype. The difference between this technology and that of ECSL's is that, ECSL videoserver uses closed captions available in the news clips. This way the burden of speech recongnition is taken off the archiving and indexing servers.

    You can read all about it at this page [sunysb.edu]

    This was developed in 1999. This is a well documented project and publicly available. During its initial days it was made available at several download sites. This is still available (documentation + sources) from ecsl website. The only problem is that, this was developed on redhat 5.2 version and used many Beta Stage libraries of gtk(--) etc. Which are now obsolete. It will take a little bit of effort to get it working on latest platforms.

    • Dremedia's solution is better and will result in a less costlier solution, compared to what is made by ECSL. The ECSL protoype is more of a "retrievel only" tech, rather than a "indexing + retrieval" type. For one thing, the latter problem is an order of magnitude harder than retrieval alone. For another, you need an already captioned content to start with.

  • There is another [shazamentertainment.com] company that plans to use pattern recognition for recognition of advertisements and music.
    BTW, it is Dremedia's technology which goes into the guts of Autonomy's tools, not the otherway round, as mentioned in the article.

  • This could be a good thing, like being able to find that episode of SNL where Burt Renolds changed his name to Turd Fegurson that you've always wanted to see again. Next thing you know, they'll come out with copy-protected tv's, you'll be SSH'ing into you're t.v., and big brother will be watching what shows you watch just to make sure you're not a terrorist.....jeez I love this country....
  • Page Two of the article is a lot more interesting to me than the first page -- the author describes the technology they're working on RIGHT NOW, and how it might be useful:

    So for now Karas is trying to get his technology embedded in high-end, professional digital video-editing equipment, where it would be used to simplify the tedious process of fast-forwarding, stopping, and scanning for the beginnings and endings of scenes. Instead, video editors would be able to enter specific lines from the script and skip straight to the parts they want.


    This, to me, is real futuristic progress! Forget watching the news at home and clicking on a link to read a related story (who can read an article and listen to TV news at the same time anyway? and if you can, do you want to?). Instead, this sort of technology would let the computer remove tedious, machine-like work for creative professionals -- like searching through 18 hours of footage to find "the bit where he mentions the monkey and laughs" -- and lets the humans focus on the things they still do way better than any computer.

    That's pretty cool.

    This kind of work has been going on at CMU, IBM, MIT, and several startups (including Virage) for a number of years. For broadcast TV, you don't even need speech recognition, you can simply use the closed captioning and programming information.

    I don't see this being a big hit with home users: the whole point about TV is to be able to lean back and enjoy the show without fiddling around. Finding and arranging video clips is a lot of effort. People who want to jump around and interact are better served with a combination of text, images, and links to video clips, like what you find on today's news sites.

    • Guess what -- only US TV is closed-captioned, and for a lot of interesting stuff (say, breaking news on CNN) the closed-captioning BITES. Even when it's good, it's not an "accurate" transcript. Speech Rec can get closer, even with errors. And it's essential if you're not interested in US TV.
      • Guess what--you are completely wrong. European television, of course, has closed captioning (it's transmitted differently, but it's the same effect) for the hearing impaired. I believe several Asian countries do as well. And you can bet that CC gets the keywords right. Furthermore, CC gets every speaker in every scene. Even if CC is somewhat of a a shorthand, that's a lot better than speech recognition, which misses entire scenes.
        • Funny, last time I watched BBC (a few days ago) there was no closed captioning. And AFIAK, very few Chinese (CCTV) or Japanese (NHK) stations have it.

          As far as CC getting keywords right -- have you LOOKED at closed captioning lately? You need to be careful -- something like CNN's captioning will be very good if a story has been repeated in their news cycle for several hours. As the news is repeated, the closed captioning is improved via an editing process, since the news doesn't change much. But on breaking stories, or anything the transcriber hasn't seen before -- it's decidedly worse. Also, watch something like Firing Line or a sportscast for a much better view of realtime closed captioning.

          And, more to the point, generating closed captioning is VASTLY more expensive both in dollar cost and labor. Speech recognition currently attains 90%+ accuracy on a problem like broadcast news, for a completely trivial cost compared to human transcribers (i.e. buy a machine, plug it in, it works forever).
          • Funny, last time I watched BBC (a few days ago) there was no closed captioning.

            If you are watching European television on a US set, you won't get it. CC is some limited, oddball US hack. Europe uses Teletext, which provides not only closed captioning, but also news, weather, subtitles, and program information.

            As far as CC getting keywords right -- have you LOOKED at closed captioning lately?

            Sure. Looks fine to me. Speech recognition systems are actually being trained with it.

            Speech recognition currently attains 90%+ accuracy on a problem like broadcast news,

            I think that's a bit optimistic. In any case, my point was not that people shouldn't use speech recognition, but that it's one of many techniques, and that all of them have been worked on by many groups for years. The real problem with these kinds of systems is that they are less useful than you might think.

            • Yes, I'm watching BBC on a US TV. I'm probably behind the times on that.

              I don't know of a single speech recognition system that is trained on CC. I work in the industry -- the transcripts aren't accurate enough. Every piece of training data is generated by a human annotator specifically generating the data for speech rec training. The words are aligned to millisecond intervals. You can't train a speech rec system on a paraphrase.

              Also, the published results of numbers of companies are in the 90% range. These are ajudicated results -- not marketing material.

              I agree with you that speech rec may be one technique -- but it's the only one that scales. People aren't going to be willing to pay to transcribe everything -- they just aren't. But people want (and should be able to) search everything -- form today's CNN to today's TVLand TV repeat. The only practical way to do that is some automatic approach.
              • Yes, I'm watching BBC on a US TV. I'm probably behind the times on that.

                Quite. The system has been in place in Europe for at least 20 years, probably closer to 30 years. It may actually predate closed captioning in the US, which I believe was deployed in 1980.

                Also, the published results of numbers of companies are in the 90% range. These are ajudicated results -- not marketing material.

                Yes, but they are results on "standard databases". Unfortunately, those do not represent real-world performance of deployed systems, no matter how carefully the databases are designed.

                I agree with you that speech rec may be one technique -- but it's the only one that scales.

                Of course, that presumes that the task (indexing broadcast video) is worth doing in the first place, which I am not convinced it is. In almost other video indexing tasks, the video clips come with plenty of metadata. And the only reason that isn't included in broadcast video is because broadcasters have no incentive for doing it (why make copying any easier than it already is).

                • Re: standard databases. The performance DOES actually represent a real-world system, as long as you have reasonable expectations of the real world system. I.e. do not train your system on a broadcast news corpus and then feed it Jerry Springer :-). But if your test and training is reasonably matched, your performance matches as well. There are real-world systems that do this.

                  As to whether the task is worth doing -- well, that's for neither of us to answer, but the market + Virage, et al -- right? :-)

                    Unfortunately, no matter how carefully you design your database in 2001, you can't predict how people speak or how they are recorded in 2003. And current speech recognition systems do not adapt well enough automatically.

    • Add a TV card with closed caption capture to your Linux box. Then setup a schedule to capture the text from shows that you might be interested in(use cron anyone). Then use that to build the search data base. Search with grep ... Now the tricky part. Use the same schedule to record things on your ReplayTV/TiVo. How? Well to make it easy use a computer controled IR remote, such as a RedRat2 on Linux [orbit2orbit.com]. Then when you get search hit's lookup the database of shows you recorded and have a macro to jump you to the show and the appropriate offset. A ReplayTV can jumpto specific offsets in a show ...

      To find shows to record you can use something like the power search utility that I wrote for my ReplayTV -> ReplayTV Search Tools for Linux [orbit2orbit.com].

      If your really up for some fun you could get a number of PVR's and play them in concert. The new ReplayTV's (4k's) can transfer shows via the netowrk/lan. Some hackers are now pulling shows off to the PC and viewing them there as well! Archiving to CD/DVD!!!! I suppose you could do the jumpto right on the PC as well, if you have the 4k.

  • Since Autonomy's software is based on statistical relevance, the speech-recognition technology doesn't have to understand every single word -- just enough to conceptually grasp what a scene or segment is about. The software begins by comparing phonemes -- slices of sound, like the syllables of a word -- to a huge probability table that predicts the context in which those phonemes may appear, and then doing that again with complete words. This language model takes up a lot of computing space and power, and only recently has it become practical to run the software on anything but a powerful Sun server. "Now we can use a twin-processor Compaq with one gigabyte of memory," Karas says.

    What I find interesting is the underlying technology they are supposed to use. Linguists (people who study language, not government translators) have been trying for years to find a way to automatically transcribe audio data for linguistic research, but they haven't had much success. Now they're telling us that a single company is able to do this with any accuracy?

    But then again, the article says that they just have to have an idea about what the scene is about, so maybe they are leaving out a lot of information. Maybe they are being over-optimistic about just how searchable their ``index'' is going to be. Now what would motivate a company to exaggerate the abilities of their product?
