TDT (Time and Date Table) provides information about date and current
time (UTC).
TOT (Time Offset Table) provides information about the local time offset in
addition to date and time.
ST (Stuffing Table) has no relevant contents. It is generated when invalid
tables are overwritten during transmission (for example, at cable headends).
The PIDs for the tables are predefined. The PMTs whose PIDs are defined in the
PAT are an exception. Each table has a table_id at the beginning of each table.
This table_id is required to transmit different tables with a single PID. The
interrelation of table type, PID and table_id is shown in Table 1–1.
