  1. Re:1750 lumens on DIY High-Quality XGA Projector for ~$300 · · Score: 1

    In addition, the red/green/blue filters cut out another 2/3's or so of the light (since through any given area, only a fraction of the color spectrum can get through).

    Then there's also the area for the TFT (thin-film transistor), plus any spacers or other non-transparent parts within the pixel grid.

    In short, LCDs cut out a huge fraction of the light passing through them.

    No, actually LEDs with that kind of lumen output from a point source are non-existent. Typical projector design requires the light source to be a point source.

    I think the only way to be more certain about a vote is to have multiple counting systems: one for each major party, plus at least one "independent" system. Each party will be represented to try and keep the other honest.

    Now, figuring out the algorithm for what to do when there's disagreement in the counts - that might take some work.

    It probably had an 8088, not an 8086. The 8088 is basically a cut-down 8086, with the 16-bit data bus multiplexed onto an 8-bit external data bus.

    Try 1.8 Mhz, Mostek 6502 (8-bit CPU). The Intel 8086 is a 16-bit CPU. The Intel 8088 is the version of the 8086 that was used in the IBM PC & PC/XT. It used a multiplexed 8-bit data bus.

  7. Re:Dual Compatability? on Gizmodo Declares Blu-Ray Winner · · Score: 1

    I was going to say the same thing. Having drives be able to read both formats would increase the costs a little, but there's no reason why it couldn't be done.

    If all drives were able to read both formats (just like all DVD drives can read CDs as well), then the consumer wouldn't have to care about the format issue. The consumer would just buy a disc, and it would work. The disc manufacturers could be free to choose the optimal format given the content they wish to market (and the manufacturing tools available to them).

    Technically speaking, the biggest difference between the formats is that Bluray writes to the near surface of the disc (from the lens' point of view), whereas HD-DVD writes to the middle surface of the disc. (DVDs write to the middle surface; CDs write to the far surface.) The result is that the different formats need different lens systems. A Bluray device already needs multiple lenses in order to read DVDs (and CDs) as well, so then it seems that adding HD-DVD capability is mostly just a matter of choosing which lens the blue laser fires through.

    Of course, there are potentially huge software compability issues regarding the higher-level formats. Then there's also licensing issues. This is probably the biggest stumbling block towards dual-format compatibility.

    Actually, the FCC recently approved the "cablecard" modular encryption standard, allowing you to use your own cablecard-compatible TV without having to use the cable-company's box. Cable companies are required to support it.

    It's a shame something similar hasn't been done to require satellite broadcasters to support standardized receiver technology.

  12. Re:Unfortunately on DVB-T STB/MPEG2 Player That Can Access SMB Shares · · Score: 1

    Actually, Dish sort-of uses a standard encryption scheme, Nagravision (and now Nagra2).

    However, they will not allow anyone to subscribe with anything other than their receivers, so it really doesn't matter if you have the standardized equipment; you have to use their proprietary boxes.

    (What this allows Dish to do is to continually change the boxes' firmware for "increased" security and bugginess.)

    In Europe, broadcasters are required to work with standardized hardware. In the US, we promote monopolies.

    Fortunately, the FCC appears to be requiring the cable industry to support the "cablecard" modular encryption scheme, allowing you to use your own cardcard-compatible TV set without a proprietary cable box. Wish they'd do something similar for satellite broadcasters.

    Wow. You know, I used to think the "problem" with the internet was that it was created in an environment of implicit trust, and thus email and usenet news etc. have problems with spam and spoofing and viruses.

    But now you've made me realize that this same problem extends to any gadget that talks to another one over any cable.

    Once paranoia becomes implicit instead of trust, you can imagine that the standard response of any gadget to any command is "why should I listen to you?" You can also imagine all the additional configuration that will be necessary to answer that challenge.

  18. Re:Over The Air vs Cable/Satellite on Current Crop Of HDTV Recorders Compared · · Score: 2, Informative

    Satellite uses QPSK or ("turbo") 8PSK, not QAM.

    The QPSK is pretty standardized, whereas the 8PSK is still being tweaked by various parties for maximum bandwidth. Of course, most HDTV broadcasts use 8PSK.

    Once you get above the encoding layer, there's the encyption. The cable industry appears to have settled on cablecard as a means for standardizing the encryption setup (I think this may have been forced on them by the FCC).

    However, unlike in Europe, where satellite receivers have been standardized, US satellite systems are very proprietary, and even where they use international standards (Dish uses DVB and Nagra encryption), they will not let you subscribe using anything but their own proprietary hardware.

    Until there's AI with "real" emotions, you'll always need "actors" of some sort. They just might not be the sort that you see on the screen, however. Even in animated films you need someone to give life to the characters, and that person has to be every bit as talented (as well as technically skilled) as your regular on-screen actor. They just don't have to look as good.

    If you've read or heard much about Pixar, you'll see that when they hire animators, they prefer people with acting talent rather than technical talent. Any actor can be taught how to use the software, they said, whereas it can be very difficult to make a good actor from an engineer.

    > What's this thing you keep talking about "wings" and two dishes?

    The FCC requires that DBS satellites be spaced ~9 degrees apart (to prevent them from interfering with each other, I believe). Therefore, the FCC designated the various spots, and various companies have acquired the rights to the different spots, or some portion of the frequency space in each spot. (In addition, the spots are also subdivided between USA, Canada, and Mexico.)

    DirecTV got all of the 101 spot, plus small portions of the 110 and 119 spots. Since these spots are contiguous and only 18 degrees apart at most, a single dish can be used to receive signals from all 3 spots.

    Dish got major portions of 110 and 119, plus portions of 61.5 and 148. The 110 and 119 spots can be received with a single dish, but a separate dish must be used to get 61.5 or 148. Those outliers are called the "wing" satellites.

    Some of the other spots are used by ExpressVu in Canada (82 and 91), while the other spots are unused at the moment (assigned to Mexico). I believe both Dish and DirecTV are negotiating with the owners of the other spots (and the FCC) to get at some of that frequency space.

    Dish has acquired some rights to the 157 spot, and in addition they are using some Ku FSS spaces at 105 and 121 (these are not DBS satellites).

    According to my calculations, DirecTV has a total of 46 transponders at 101+110+119, while Dish has 50 transponders at 110+119. In addition, Dish is using 15 at 61.5, plus 22 at 148, plus 24 at 105, plus 28 at 121, plus 3 at 157.

    Perhaps you can see why DirecTV is looking to make some big changes.

    Looking at Dish's 110/119 satellites, I see up to about 12 regular channels or 3 HD channels being crammed onto a single transponder. This is really pushing things, and the result is a lot of compression artifacts. Way back when (before locals), only ~6 regular channels or 1 HD channel would take up a transponder.
