Tables Description
Below is a brief explanation of the main tables that can appear in the detection
of a TS. For more details we recommend to consult guidelines ETSI TR 101 211.
There are two generic groups of tables:
PSI
(Program Specific Information) Tables: These tables are specified by
the MPEG-2 standard worldwide. They are used by all the digital
transmission standards. The TS analyzer detects all the PSI tables.
SI (Service Information) Tables: These tables are specified by the
standard used in the area or country (in this case DVB). These tables are
more detailed and imply a higher level of information relating to the PSI
tables. The TS analyzer detects the most important SI tables. The PID
(Packet Identification) code next to the name of the table is a 13-bit code
that identifies each packet type and therefore to what kind of table
corresponds.

PSI Tables
PSI tables are:
PAT (Program Association Table): It is a master table that lists all services
found in the TS being transmitted. It also points the table where are
specified each one of the services.
PMT (Program Map Table): It is a table that identifies all the components
within a service (video, audio and/or data).
NIT (Network Information Table): Optional table with information about
TS and multiplex of a given network. The content in detail is described in
the tables used by the digital standard (DVB in this case).
CAT (Conditional Access Table): Table that controls the scrambling of a
service.
►
SI Tables
Most important SI tables are:
NIT (Network Information Table): It is a master table used by the
broadcasting network to manage the services. It provides logic network
info by grouping several TS together and adding tuning information for all
network services. In the case of a satellite provides information about its
channels. It also contains the LCN descriptor that provides information to
order the services.
BAT (Bouquet Association Table): It is a table containing information
required to group a set of services or content, which is related for
