It's apples and oranges, but since A-VSB and Dotcast at 4.5 Mb/s were
mentioned together, the difference in C/N margin is 40 dB for Dotcast
vs 1.7 dB, or 4.5 dB, for A-VSB. That's a huge difference. Granted,
that's without TV programming on the A-VSB channel. So cut that down
to 1.5 Mb/s of A-VSB, and you can add a very nice few SD channels and
get extremely robust Moviebeam.
On paper, all of that is true. In practice, I still await the
5th-generation LG STB, first shown publicly more than three-and-a-half
years ago, and successfully tested in my apartment in July of 2004. No
other commercially available box has successfully picked up DTT in my
apartment with a set-top antenna. Meanwhile, my set-top rabbit ears
bring in all NYC analog stations at good quality or better.
I know DTT CAN work. I've personally successfully tested both ATSC and
DVB-T. But, to date, no one has put an STB that will work in my
apartment on the market. So, if MovieBeam is willing to sell me a box
that works in my apartment (though I have no desire for it), they've
taken a step that other CE manufacturers haven't.
By the way, I just entered a bunch of addresses of friends on the
MovieBeam site, and it says they all have service. Maybe I need a more
rural set of friends?
TTFN,
Mark
