Bottom line is that if analog TV goes off the air, ATSC will have to take its place. All the fancy protocols they're considering aren't essential to the basic mission of informing the public. What I think is essential are protocols that allow consistent info to be disseminated simultaneously over all mass media.
Well, let's not get too pompous about this. NTSC is also not the best system for homeland security, right? These are supposed to be low-cost commercial solutions which in a pinch are re-purposed to disseminate emergency information. No one pretends that they are systems built and optimized from the ground up for emergency services. They are clearly not. If they were, they would not be affordable by the masses.
I figure, if I can use my rabbit ears to pick up several stations from several diffent directions (check), and each one can transmit multiple subchannels (check), and the subchannels can present radar pictures with warnings about bad stuff sent in real time (check), that's not a bad "in a pinch" system. Heck, even if all DC stations go off the air, I can still receive Baltimore.
