PSIP: The PSIP menu gives the Program system information (PSIP). Types of information are PAT, PMT,
MGT, VCT, EIT, and STT. This information comes from the incoming stream and contains the necessary data
for the de-multiplexing of TS and successful regeneration of the programs. The idea of sending multiple
programs within the physical channel (19.39 M bps) is made possible by the digital compression system
used. To compress the image for transmission, MPEG compression is used. It reduces the amount of data by
about 55 to 1. The MPEG allows picking both the screen size and bit rate when encoding, also choosing a
variety of bit rates within any of the resolution modes.
PAT: For displaying information about the PAT (Program Association Table) in the stream. The PAT gives
information about the number of programs located in the stream. There is only one PAT per stream and the
PAT is always present in an MPEG compliant stream. The information displayed in the Alphanumeric
includes the program number, the PMTs PID, the TS Stream ID, and the version number of the PAT table.

PMT: For display information about the PMTs (Program Map Table) in the stream. The PMT gives
information about each program located in the stream. There are as many PMTs per stream as programs in
the transport stream and the PMTs are always present in an MPEG compliant stream. The information
displayed in the Alphanumeric includes the PMT PID Number, the Program number, the version number of
the PMT, location for PCR and elementary PIDs like video and audios.
MGT: For displaying information about the MGT (Master Guide Table) in the stream. There is only one
MGT in an ATSC compliant transport stream. This screen will display the information about the different
tables included in the stream. Those tables include RRT (Rating Region Table), T-VCT (Terrestrial Virtual
Channel Table), C-VCT (Cable Virtual Channel Table), EITs (Event Information Table), ETTs (Extended
Text Table).
