Individual addressing functions (packet_type 2116) can be sent at any time.
The T2 timestamp refers to the transmission time of the super frame, although it is sent
at any time.
The figure below shows a single PLP. If using multiple PLPs, the interleaving frame
duration TIF and hence the timing requirements for the type 0016 packets can be different for different PLPs.

At your IP source, set the "transport stream packets per internet protocol packet" (TP
per IP) parameter as follows:
●
If TP packet length= 188 bytes: Set TP per IP to 7 or 6.
●
If TP packet length = 204/208 bytes: Set TP per IP to 6.
We recommend that you use a separate LAN infrastructure to stream the transport
streams via IP to the IP connector of the baseband board. Also, avoid TS packet losses during IP transmission.
