    rather than duplicating frames as most 100hz does, it says "well if the ball is in the top left in frame one, and in the bottom right in the second, then it must be in the middle at the between point", it then inserts the additional frame accordingly. It works surprisingly well - in fact it can make it look so much more realistic that it looks fake sometimes Well, one of the main reasons that film and traditional interlaced analogue video look different is that film updates 24 or 25 (*) frames a second and video updates 50 (PAL) or 60 (NTSC) fields (half-frames) per second. (**)

    So video really does have 50/60 fields-per-second motion resolution versus film's 24 or 25 frames, and that's one major cause of them looking different.

    Now, if you have a system that invents interpolated frames then you're effectively increasing the motion resolution and this will inevitably give the material a more "video-like" look (presumably the effect is heightened if you go beyond traditional video's 50/60 fps and go up to 100 fps). Since most American dramas are shot on 24 fps film (see (*) again), increasing this to 50 or 100 frames per second will alter the appearance, making it more "video-like". It may be this that you think looks "so realistic it looks fake". Video is used for factual stuff, and by camcorders and so on. Drama is mostly shot on film and has a more "distant" and (ironically) less realistic look due- I'm guessing- to its lower motion resolution. So subconsciously you're probably used to this feel on non-factual material- and when it looks like video instead (as increasing the frame rate by interpolation will do) your brain says "something wrong".

    It's also possible that the interpolation isn't consistent- if some objects get better motion-interpolation than others, the mixture may look slightly "wrong". I don't know- I haven't seen it.

    (*) With PAL systems the pseudo-"whole"-frame rate is 25 fps, so most films are simply speeded up slightly. NTSC is more complex because it has 30 fps, and you can't speed up that much- a more complex process is used. But either way, transferring film to video still results in 24 or 25 complete frames per second- you don't get increased motion resolution because it wasn't there on the original source, and with PAL, the same frame is recorded onto odd and even-numbered video fields.

    (**) Although one might think that 50 half-frames per second = 25 full frames = roughly the same, it doesn't work like that- since pre-digital video systems have no "memory", if an object has moved between the odd-numbered lines being recorded (field #1A) and the even lines being recorded (field #1B), then it will be in a different position.

    Slight tangent, but apparently the "H" in HQV stands for Hollywood.

    I don't want to go too far into the details, but the processing I had in mind would be a combination of several ideas I'd been mulling over, many of which would require tracking a given object over several frames to average out noise, artifacting errors, and so on. And also to use simultaneous-equation-style processing on the multiple frames of the same object to increase the static resolution (or maybe this could be done more simply by aligning, overlaying and resharpening the multiple copies). Also ideas like more intelligently spotting the difference between genuine detail and pseudo-detail which comes from encoding/compression artifacts, and removing or repairing the latter. (Repair- or guessing what the most likely hi-res detail was that caused or was damaged by the artifact- might be one of those "easier said than done" computationally intensive tasks). Again, easier if you are looking at multiple frames.

    I'm not an expert in this area, but I suspect those that are have probably come up with similar ideas. Whether they're doable in reasonable time, and in hardware is more open to question.

    DVD really didn't take off until 3-4 years after it came out, when the players got really cheap. Which was my exact point! Even though the Blu-Ray/HD-DVD battle that everyone was excited about is supposedly all but over, the less interesting, but ultimately much bigger war- to get people to buy hi-def players at all- isn't. As I said, the quickest way to overcome that *is* to reduce the price.

    Although I don't think it'll happen here, it'd be quite possible to end up with one side technically winning, but still doing badly. Who won out of DVD-A and SACD? Who cares, because neither grabbed a notable share of the market, and hi-def audio as a whole flopped commercially.

    Personally, I don't think interest in HD as a whole will flop the way that hi-def audio flopped. That doesn't mean Blu Ray should rest on its laurels, however. The most obvious problem with keeping the price high would be that it slowed adoption (as you imply).

    Even if the Blu Ray camp could live with that (it'd probably make them more profit in the short term), it'd be a bad idea, simply because of the other understated factor- downloadable HD content. The market is moving that way anyway, and at this stage I reckon it's ultimately a much bigger- but less tangible- threat to Blu-Ray than the moribund HD-DVD.

    In short, the battle's not over. Blu Ray faces threats from current-generation DVD and apathy on one side and the should-have-seen-it-coming threat of downloadable content bypassing their petty squabbles on the other.

    The GGP was so wrong- Blu Ray players need to come down in price as much as ever.

    If you buy more discs, you're investing in a dead-end system, and when your original machine breaks down, you'll likely have to buy a secondhand player in a few years time if you want to keep watching your collection. Which might not have the benefits of newly-built (and Blu-Ray only) hi-def players- and what if you want to use them in your computer(s)?

    Now there isn't a reason to lower the cost of bluray players. Yes there is. Though many (but not all) overlooked it in favour of the more interesting Blu-Ray/HD-DVD rivalry, both players were fighting a bigger rival- existing DVD players and public apathy.

    DVD became a runaway success because (a) it was cheap, and (b) it gave noticable picture-quality improvements and other advantages that could be enjoyed with existing setups.

    Blu-Ray is not only relatively expensive, but it requires an HD set to make it worthwhile. Even those with HD sets could stick with upscaling DVD players. (*) And I suspect there are a significant proportion of people who rushed out and bought HD because it was the latest thing and they could boast about it to their friends, and haven't noticed that the picture from their $30 DVD player connected via the composite cable actually sucks :)

    I discourage people who don't know what they're talking about from talking as if they do. In other words, people who don't know about the law shouldn't say "the position is X, Y and Z" when they're just guessing or downright incorrect.

    I'm quite happy for other people to discuss aspects of the law, just as I do. However, if I am in any doubt as to my understanding when I'm not an expert on a subject, I try to make this clear. Something along the lines of "AFAIK, this is what the law says, but I'm not an expert", so that I don't mislead people.

    The whole reason for Slashdot and forums is that if you take enough people focusing on one subject, you usually get what amounts to a thesis (when you find all the important information/thoughts) on that subject. No, the whole reason for Slashdot is to report news that is of interest to nerds, and to give them a place to discuss it.

    The fact that on technical matters, an acceptably high proportion of the Slashdot userbase is knowledgable enough to discuss things insightfully (and in most cases to make clear which comments are misleading) is a happy side effect.

    I don't think it had any such lofty Web-2.0-style ambitions when it started, and I still don't think it would describe itself in such a pompous manner.

    On the other hand, when the proportion of people who have any real knowledge of the subject drops below a certain threshold, this doesn't work. That's what happens with discussions on how the law *actually* works. Geeks think they can work round their ignorance of how the law *actually* works by making unstated assumptions and assuming they can logically deduce these things.

    The only way to actually know how the law actually works is to find out about it. (How it *should* work is a different kettle of fish... but I repeat myself).

You could start formatting a disk, turn the computer off, and the drive would complete the physical format, although it wouldn't write the filesystem.

    Therefore (*IIRC*) the physical disk formatting that you could create with the drives was limited to those that the drive's circuitry- and hardware- was designed to handle. I'm not sure if there were any sneaky ways around this- getting low-level or pseudo-low-level access to the formatting circuitry- without actually modifying the drive itself. I *do* know that there were many circuit boards for the 1050 drive that improved its performance and let it copy more disks.

    And (getting back to the parent's reply), if a standard disk image relies on the "normal" expected disk layout and doesn't include support for nonstandard physical hacks like duplicate sectors *and* the emulator doesn't replicate the pseudo-random timing/read issues of the physical drive rotation, then you can't replicate- let alone run- a copy protected program on one.

    (**) The obvious route around this, of course, is to simply bypass or disable the code that checks for copy protection. Easier said than done maybe, but certainly doable- after all, you have to be able to read the program to load it, and once that's done it's a question of finding the protection and rewriting the hacked version to an ordinary disc.
