So yes, they must rob something in the total allocated 19.4 stream to add DTV. Now if they had null packets before changing no OTA is harmed. But if they didn't have any null packets (bandwidth not used) then they robbed bandwidth from one of their OTA channels to make room for Mobile TV.

Can't get something for nothing in bandwidth world, well unless you are a news reporter and don't understand anything you report.

Pig, what about a station like my local PBS broadcasting 1HD channel and 3 SD subchannels? I'd imagine they're all tapped out on bandwidth, and won't be able to add a Mobile DTV stream?
