Remember: this patent was requested years before Siri.
Therefore the newly granted patents could be a head fake by Apple. Part of a 3-step plan:
1. Get patents on TV-related technology that they will never implement.
2. Sit back and watch would-be competitors scramble to do something similar (yet somehow non-infringing.)
3. Release a vastly better implementation that leapfrogs the old patented technology and competitors' products.
Apple's solution would of course use other patented technology, possibly filed under a more far-reaching category than just "television interface." Apple would thus have patents on the best technology (used in the television product they actually do release) and the second-best technology (the patented technology all the would-be competitors try so hard to mimic without infringing.)
This would leave the competitors years behind, with brand new products based on obsolete technology.
Does that sound like a good plan? I think so.

I find it even more amusing that people get upset about other people using that name. Who cares what people call it? It's like people calling an iPod Touch an 'iTouch'
And anyway, all the iDevices have two-syllable names: iMac, iPod, iPhone, iPad.
If Apple really wants to remake the TV industry in their own image, they'll need a more clever name than "iTV" for their television set. And it will need to be two syllables.
