PSIP (PROGRAM AND SYSTEM INFORMATION PROTOCOL)

PSIP is a standard set by the ATSC that provides a methodology for transporting DTV system information and electronic program guide data. It allows broadcasters to identify themselves when you tune their channel. It can be information such as call letters and channel number. It can also convey up to 16 days of programming information. Consumer receiver manufacturers can use PSIP data to display interactive program guides to aid navigation of channels in the DTV receiver.
