Splice point insertion can be controlled from SCTE104 messages, either in VANC or
from the control IP input.

The DPI_PID_index value contained within the SCTE-104 message is not a PID. It provides a way of addressing a
particular VCM within a multi-module unit to ensure that the SCTE104 messages are received by the specific
encoder. It is a 2 byte value.
Table 3.27 DPI PID Index Value
Bit Description
15..8 The option card slot number (1 to 6)
7..0 The encoder channel on the option card
Note: All option cards referenced in this manual support only 1 channel of video. If
the channel is set to 0 or 1 the encoder will have splice points inserted.
If the option card slot number or the encoder channel does not exist the Video
Processor will return a splice failure message.
