My own suggestion is we all argue pointlessly until the end of Feb 2009,
just to pass the time until we have some hard facts. ;-)
Hard facts???? How about this:
8VSB doesn't work as an *equal* NTSC replacement. Period.
It does not work nearly so well at communicating emergency information
in a disaster scenario as does NTSC.
Would you be at all concerned if you were relying solely on an 8VSB
broadcast to "SEE" what the hurricane looks like that is headed your way?
Please answer the following questions:
What differences will occur between now and the end of Feb, 2009, in
terms of how easily or poorly we will all then receive 8VSB broadcasts?
Will the loss of analog broadcast signals in Feb. make a significant
improvement in 8VSB reception as opposed to the poor, uneven, randomly
unpredictable reception we have now?
Is there a spreadsheet that accurately predicts for each metropolitan
area the channel by channel expected improvement in 8VSB reception in
the latter part of next Feb?
Is there a similar spreadsheet with a timetable that accurately predicts
8VSB reception improvement *or degradation* when all the digital
stations now broadcasting with their 'on-loan-from-the-FCC' channels
give them back and resume digital broadcasting on VHF channels or other
UHF channels?
Have all of this two-part transition been thought out, tested, verified,
thoroughly discussed and re-tested and have all possible scenarios been
run with computer models?
A sense of scale for the above question:
I'm thinking here in terms of the interestingly accurate 'spaghetti
track' computer models predicting the expected paths for hurricanes
being shown for the last few weeks on TV.
Is there anything with that kind of accuracy [or better] that can
properly predict what will happen to 8VSB when the final shoe drops?
