    I'd have thought because of noise and attenuation? Having said that I did used to run an audio cable from one side of my home to the other, never noticed any problems - but then I'm no audiophile.

    Perhaps look at a bifferboard? http://bifferos.bizhat.com/

    £29 for a tiny low-voltage machine that can play a wav that's being streamed over the network. Someone wrote a howto here: http://sites.google.com/site/bifferboard/Home/howto/use-bifferboard-as-network-audio-player

    You'd still need to sort out speakers, and figure out a way to control it, but I'd have thought it would be fairly straight-forward to set up an IR controller or start/stop/next buttons to play a pre-defined playlist.

    Do we have to use virtual glasses and other sensory support systems. I mean is it based on virtual reality. http://veera.bizhat.com/

  6. Re:How can the Chinese become a software superpowe by amightywind · · Score: 1 · on First Hand Look At Chinese Internet Censorship

    I dont see them surpassing India anytime, if this is the trend... Hardware...maybe.. software ... never!

    A common notion has developed that Indian IT consists of software only. China emphasized this a few weeks ago when Wen Jiabao spoke fancifully about dividing up the IT market with software going to India and hardware to China, with his twin pagodas remark. I don't see India going along with this silly stereotype. Thier potential market advantages in hardware are the same as China's. Expect them to compete fiercely.

  7. Re:Satellites are linear not digital by dcm1101 · · Score: 2, Informative · on DirecTV's 1st MPEG4 Satellite Launch Successful
    Well, there are web sites that allow you to enter your latitude and longitude and the orbital slot of a satellite, and then they do the math for you to get the azimuth and elevation. Or if you're a math geek, you can do the math yourself. Then, if you had an extremely accurate compass/inclinometer you could try to aim the antenna that way. In actual practice, I doubt that would work reliably - hitting a target the size of a car from 22,000 miles away is a very touchy business. Most pros use a compass/inclinometer to get to the right portion of the sky, and then hook up a spectrum analyzer to find the nearest satellite, and then 'stair step' across the arc until they find the bird they want. Being able to ID a satellite by its spectrum plot is a little bit of an art, but allows you to at least confirm that you're looking at a satellite. You can always hook up your IRD at that point to check of it's the right satellite. The problem with just tuning using your receiver on a digital signal, is that below a certain threshold the signal will not lock up, so be prepared to spend all day moving your dish 1/4 of a degree at a time, and waiting 30 seconds after each move to see if it locks up.

    Ironically, the smaller dishes are easier to aim, since their gain is so much lower. Remember, a satellite dish is simply a telescope that operates on microwave frequencies rather than visible light, so a more powerful antenna "sees" a much smaller portion of sky, and consequently gets a much better signal. Having aligned 1.6-meter dishes and 12-meter dishes, I can attest that the 12-meter gets a great signal, but is harder to aim.
