Setting Up the DPI,
29. 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.
30. Click Apply.
To Set Up the DPI via the HD-SDI Input (SCTE-104 standard)
Proceed as follows to set up the DPI messages embedded in the HD-SDI input
signal:
1. From the user interface of the D9054 HD Encoder, click the DPI tab.
The GUI displays the global DPI message information. This page is also used to
enable the DPI messages embedded within the HD-SDI signal (see step 8).
2. In the DPI ES section, set the PID of the DPI.
This is the transport packet PID of the DPI stream. You may type a figure in the
range from 16 to 8190.
3. Enable the Reserve Bandwidth.
This enable or disable generation of Bandwidth Reservation packets.
