In summary, if the Activation Flag is set to 0, the DTA will not enter Normal Operations Mode. If the Timeout
Counter has reached 0, the DTA will revert to Pending Initialization mode.
2.4.3 Network PID Monitoring
In Pending Init Mode, the DTA is filtering for Network PIDs carrying the SI data (SCTE-65 tables). Determination
of the Network PID value is discussed in Section 2.3.1.2. The DTA supports all mandatory SCTE-65 tables
associated with Profile 2. The DTA does not support nor require optional tables associated with SCTE-65 Profile 2.
It is highly suggested that all QAMs carrying DTA services carry the Network PID and SI tables. In this way, it
will be assured the DTA will receive channel map updated and code download triggers.
2.4.3.1 VCT ID Assignment
By default, the DTA is looking for SI associated with VCT-ID 0, until a message from the headend indicates
otherwise. The DTA will filter the Network PID and tables associated with its assigned VCT ID. It will load the
channel map once it has been completely downloaded.
Note, in order for the DTA to enter Normal Operations Mode from Pending Init Mode, the DTA must load a channel
map.
2.4.4 Pending Initialization Mode On-Screen Messages
If the DTA is in Pending Init Mode for more than three (3) seconds, the DTA will display one of two messages: the
Activation Support Message or the Service Interruption Message.
The DTA will display the Activation Support Message if any of the following conditions are met.
1. Activation Flag is not set
