PSIP can also send:
PSIP is defined in ATSC standard A/65, the most recent revision of which is A/65C, published in 2006. A/69 is a recommended practice for implementing PSIP in a TV station.
PSIP also supersedes the A/55 and A/56 protocol methods of delivering program guide information (which the ATSC has deleted). TV Guide On Screen is a different, proprietary system provided by datacasting on a single station, while PSIP is required, at least in the United States, to be sent by every digital TV station.
PSIP information may be passed through the airchain using proprietary protocols or through use of the XML-based Programming Metadata Communication Protocol (PMCP, or ATSC A/76) facility metadata scheme.
¹ indicates a US FCC requirement
Implementation of the DCC feature is entirely optional, and depends on development of receiver and decoder technology. For example, a digital video recorder 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.
