If they can do 'pre and post editing' as stated for ad revenue generation and recognition you would think with ads at HomeDept they'v though of how to get rt-feedback via instant-prompts for cell-phone end-user interaction; imo it would be done within the 'stream controler technology' that the tipMotion uses within the server-side functions.
noting - i think, these broadcasters are on other frequencies than cell; and if they start h.26 push/pull it'll be another sweet-spot because imo free MobileTV is a must have if your phones SW-chip set can do it, but as stated these are DTV centric like IPTV ergo subchannels allowing many venues/content possibilities.
