  1. Re:I'm more concerned about ESD. on Silent Microchip 'Fan' Has No Moving Parts · · Score: 1

    much of the noise from fans comes from the noise as the air blows over the heatsink etc. and not from the fan itself.

    This is largely a myth. Unless you have super high air-speed fans, the turbulence is a minor noise generator. With the popularity of low speed and 80mm+ fans, this situation has almost entirely disappeared.

    DVDs are in fact based-upon NTSC.

    You are completely and totally wrong.

    While those interlaced fields can be back-converted for progressive display, the information is still stored on the disc as 480i at 60 fps.

    Video on a DVD can be stored interlaced, but most commercial DVDs are progressive 24fps. Most players output that material interlaced, but the data on-disc for movies is still almost always progressive.

    DVD is essentially NTSC-III (digitized NTSC).

    NTSC is not a resolution and frame rate. It is an RF encoding of analog data. Digitized video can never be "NTSC".

    To make the point clear, go put a "PAL DVD" in your DVD player (it has to be region free)... It will still work and playback just fine. With an analog formats, where "NTSC" means something, it won't work at all.

    DVDs are digital NOT NTSC. They use approximate NTSC resolution, and the overwhelming majority use ~24fps (24/1.001) progressive, rather than 30i.

  6. Re:Renewed niche for broadcast TV? on Hobbyists Create GPLed DIY Super TV Antenna · · Score: 1

    What makes broadcast relevant again is having the Internet to compliment it.

    I think the DVD, Netflix, and DVRs have a LOT more to do with it.

    DVDs have changed the way people watch TV. Why wait for the repeats of TV shows with all the commercials and annoyances, when $10 will get you a hard copy? Why wait for some blockbuster or B-movie to show up on TV, when it's on the shelf at the supermarket?

    Netflix fills a very large niche for movies and TV shows you didn't see, but think you might like. Not to mention older or cult movies that probably aren't ever going to be on TV, anywhere. If I had to chose between 3 movies at a time, and 200 channels a month, I'd go with Netflix. And don't bring the internet into it, I'd have subscribed to Netflix if they shipped out hard copies of their movie catalog, and required me to create my queue with pencil and paper.

    DVRs are having a huge impact as well, they may entirely eliminate the need for cable channels that do nothing but syndicate TV shows... If you watched EVERY single episode of Law & Order when it was first aired, you're not likely to watch repeats of it. If you can record the weekly 2:00 am airing of Star Trek on NBC, and watch it anytime, why would you need 5 cable channels that show it around the clock?

    plus Internet for pre-recorded stuff people want on demand.

    DVRs and DVDs both largely fill the need for on demand shows, as well as fringe/small-audience content.

    Unfortunately, NTSC isnt going anywhere. Its just the analog transmissions which are going away.

    NTSC is the analog encoding of RF TV signals, it is going away with the switch to digital (replaced by ATSC), just as PAL did in many places in Europe (replaced by DVB-T).

    The old resolution isn't even being kept, as 1080i is universal. So the only vestige of NTSC is the ~30 fps rate, and there are alternatives to that as well, they just aren't commonly utilized.

    Why you Americans dont use PAL, I'll never know. :)

    You're absolutely right! The $200 PC is infinitely more capable than any Tivo could ever DREAM of!

    That much is true. However, there are innumerable problems with CableCards, and simply using analog pass-through is both more flexible and can give even better results (eg. smaller files with potentially visually better quality through on-the-fly encoding/processing).

    This is simple economics. Opportunity cost.

    You're the one who doesn't grasp economics. You obviously aren't going to be working every (spare) waking hour, so there is no opportunity cost here. If putting together a DVR required you work on nothing else 24/7 for weeks, THAT would be an opportunity cost. But that's not how it works. ie. No opportunity cost.

Yes, MythTV's UI also sucks, but it's a piece of crap I wouldn't dream of using or recomend. It's merely the press' favorite.

    It's all superior to every other DVR I'd seen.

    Obviously your experience is far too limited, but let's just go with it as a hypothetical...

    Does your Tivo3 allow you to watch DVDs without being forced to watch trailers? How much of your time is wasted on every FBI warning and forced trailer? How many such DVDs will it take before it would have been quicker (or CHEAPER for you) to put together a DVR?

    Better yet, does your Tivo3 allow you to STORE all your DVD, VHS, etc. movies on it's hard drive, so you never have to waste your time (or MONEY for you) removing them from the packaging, waiting for your DVD player to power up, cleaning them, etc?

    How's your Tivo doing, replacing your CD player and disc collection?

    How well does your Tivo allow you to edit out commercials, so that you don't have to skip through the commercials every time you want to watch a show that you've saved?

    How good is your Tivo at allowing you to convert any videos to DVDs (or VCD/SVCDs) so you can give hard copies to other family members (eg. kids) to watch in another room and not bother you, or to give out?

    How often do you think you're going to need to replace your Tivo, because it runs out of space or doesn't support some feature like CableCard2 or HDTV/QAM? What's the opportunity cost of losing all your saved shows and the like?

    What's most disturbing about your post isn't how utterly wrong you are on all counts, it's how utterly sure you and your actions are the only right ones, and everyone else MUST be wrong, somehow.

There are huge, huge numbers of glitch-free flights every day (but they all have to pay for uplinking numerous megabytes of data per hour), and only the very tiniest fraction of aircraft ever need that flight data examined.

    They should keep the crash-proof boxes, for events that stop the streaing before the recorder stops.
