Setting Up the DPI,
4. Set the bandwidth's Reserved Bitrate.
The bandwidth reservation bit rate describes the packet bandwidth of the DPI
stream in bits per second. Possible range is 1504 to 90240 bit/s.
Note: The bandwidth reservation bit rate is typically used in connection with
encryption of the encoded signal so that the splice cannot be detected.
5. Set the Heartbeat Interval (Duration Period).
The heartbeat is used to signal a live DPI PID connection.
Possible range is from 0 to 3600 seconds between heartbeat packets.
Note: Typically you won't need the heartbeat duration setting if you have set
the bandwidth reservation bit rate to a value other than 0.
6. Set the Repeat Count.
This is the number of times the splice message is to be repeated.
7. Set the Interval.
This is the repeat period for the number of repetitions of splice message
generation. The default is 1000 ms.
8. In the Trigger Information section, select the first Enable check box (i.e.,
Message 1) to enable the DPI message(s) embedded within the HD-SDI signal.

message
9. Set the Relative Delay in the range from -10000 to +10000 ms. The default is 0.
This value is used to mathematically manipulate the PTS timestamp to
compensate for known external delays from the DPI source. A negative relative
delay cannot be less than the current PCR base value plus 4 seconds. If this was
the case, it would mean that the splice was defined to occur before the packet is
physically placed in the multiplex.
