As I’m writing this, the eye of Hurricane Ike is roughly ten hours from landfall.  The weather here, maybe 60 miles inland, is overcast with mild wind.  Meanwhile, the storm surge has already knocked out power for ten thousand homes along the coast, claims the TV news, humming along in the background as I write this, which brings me to a thought.

Next year, analog TV gets turned off, and it’s digital or nothing.  Well, what happens in bad weather?  Analog TV degrades somewhat, but is still watchable.  Digital TV works great until it starts getting uncorrectable errors.  There’s a brief period where you see block reconstruction errors and, with even a mild additional amount of error, it’s just unwatchable garbage.  According to AntennaWeb, most of the terrestrial broadcast towers are maybe ten miles from my house, but that’s ten miles closer to the coast.  However, I get TV from Comcast, my local cable TV provider.  As I’ve watched the HD feed today, it’s been spotty.  Good for a while, unwatchable for a while.  The analog feed, which we also get on a different channel, has been spot on the whole time.

From this, it would appear that Comcast is getting its feed out of the air, and thus has all the same sorts of weather effects that I would have if I bothered to put my own antenna on the roof.  Next year, when the next hurricane is bearing down on the coast, and digital TV is the only TV around, it’s an interesting question whether I’ll get something useful on my TV during a disaster.  Dear Comcast, Engineering Department: please get a hard line between you and each of the local major TV stations.  Better yet, get two of them, each, and make sure they don’t share any telephone poles.

[Sidebar: In my old house, I used DirecTV plus a terrestrial antenna for HD locals, run through a DirecTV-branded HD TiVo.  Now, I’m getting everything from Comcast, over telephone poles, into a (series 3) TiVo-HD.  In any meaningful disaster, the telephone poles are likely to go down, taking out my TV source material. I get power and telephone from the same poles, so to some extent, they make a single point of failure, and thus no meaningful benefit from putting up my own antenna.

Once the storm gets closer, I’ll be moving the UPS from my computer to our, umm, shelter-in-place location.  I don’t expect I’d want to waste precious UPS battery power running my power-hungry television set.  Instead, I’ve got an AM/FM portable radio that runs on two AA’s.  Hopefully, the amount of useful information on the radio will be better than the man-on-the-street TV newscasters, interviewing fools standing along the ocean, watching the pretty waves breaking.  Hint: you can’t “ride through” a storm when the water is ten feet over your head.]
