Requirements
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 los-
ses during IP transmission.
