I'll look into this - you pointed it out to me before...
When you ask the Q how to request the information and bring in the Q of obtrusivness... we'll H.26 and IPTV have encountered this and if you look closely you'll see Microsoft has IPTV a two-way street... full-duplex lol... if/when a person sees an ad or even something on a show they can get instant info on it, and if incorporated with DVR, which btw do not incorporate an SD slot or except blutooth input yet (wink-wink), it doesn't even interupt your show. I havn't looked at IPTV in a while but I imagine it'd direct you inquiries to a subchannel so to not interupt, where you could view at your discression. Actually no reason any sellected phone ads, couldn't be buffered into a place for future inquiry when time allows. who knows
The obtrusivness is a factor avot, the carriers and everyone else is probably working on as we speak... per mobile video.
the bar code aspect is compelling.
