Table 3.14 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.
It is not possible to insert splice points into the video which are closer than 1 second
apart. Any messages received with a splice time within 1 second of another splice
point and with the same splice_event_id will be treated as a duplicate of the initial
splice request and deleted.
Any messages received with a splice time within 1 second of another splice point
and with a different splice_event_id will be aligned to the initial splice request. This
will result in 2 SCTE35 messages being generated containing the same PTS value
but different splice_event_ids and 1 splice point inserted into the video, unless the
auto return is set to 1 and the duration is populated, in which case the video PID will
be conditioned for two splice points.
3.18.2 SCTE104 Over IP
SCTE 104 messages can also be sent to the unit over the control port. The DPI TCP
Port on the unit is 5167 by default. This parameter can be accessed on the GUI
through Device Configuration > Advanced Setup > Base Unit.
3.18.3 How to Configure Splicing
1. If you have not already done so, create a Transport Stream and a service as
described in Chapter 5, Web GUI Control.
2. Go to the Inputs widget of the Service Configuration page and select the
Video SCTE 35 Stream from the VCM inputs tree and drag it into the required
output service.
3. Select the required source from the Splicing Control drop down box in the
Properties widget (see Section 3.19 for additional requirements for GPI
triggered splicing).
