The PIDs and the table IDs for the service information have been per-
manently allocated within DVB in Table 3.2.
The PSI/SI tables are linked to one another via the most varied identifi-
ers (Fig. 3.45.). These are both PIDs and special, table-dependent identifi-
ers. In the PAT, the PMT_PIDs are chained together by way of the
prog_no. To each prog_no, a PMT_PID is allocated which refers to a
transport stream packet with the corresponding PMT of this associated
program. The prog_no can then also be found in the header of the respec-
tive PMT. Prog_no = 0 is allocated to the NIT where the PID of the NIT
can be found.
