About PSIP
Program and System Information Protocol (PSIP) is
data that is transmitted along with a station's DTV signal that
tells DTV receivers important information about the station and
what is being broadcast. The most important function of PSIP is
to provide a method for DTV receivers to identify a DTV station
and to determine how a receiver can tune to it. PSIP identifies
both the DTV channel and the associated NTSC (analog) channel. It
helps maintain the current channel branding because DTV receivers
will electronically associate the two channels making it easy for
viewers to tune to the DTV station even if they do not know the
channel number.
In addition to identifying the channel number, PSIP
tells the receiver whether multiple program channels are being broadcast
and, if so, how to find them. It identifies whether the programs
are closed captioned, conveys V-chip information, if data is associated
with the program, and much more. If broadcasters do not include
properly encoded PSIP data in their DTV signals, receivers may not
correctly identify and tune to the station. Therefore, it is vital
that all broadcasters understand PSIP and include the data in their
DTV stations signals. PSIP is a mandatory Advanced Television Systems
Committee (ATSC) Standard.
