Most TV's can display a QR code (as long as it's not too detailed), but the main issue is the dwell time. I've yet to meet an app that can go from off-in-pocket to scanned QR code in less than 5 seconds. Add in user reaction time and decision time and you've pretty much wasted a 30 second infomercial spot. Might not be such a bad idea for 60+-second infomercials though, as long as they keep reminding the viewer that the code is coming up.

QR codes are too small. The user would have to walk up to the TV.
Also Shazaam is doing it with their music fingerprinting.
