The DCC function lets broadcasters tell a DTV receiver where to change, based upon the viewer's settings. This is most likely to be a ZIP or other Postcode , which can select Demographic ally-based programming to show, such as TV Commercial s or Weather Bulletin s, possibly taken from an accompanying Datacasting channel.

Implementation of this feature is entirely optional, and depends on development of Receiver and Decoder Technology . For example, a PVR -like Computer Memory Device could record commercials broadcast at other times for later replay, so that many more different commercials could be shown in different parts of a large Metro Area than can actually be transmitted at once.
