Getting Started
Table 3.15 Splicing Control Options
Option Description
Off No splice operation
On VANC message only
SCTE104 messages in VANC will be passed through as SCTE35 messages
that can then be added as a component in the output transport stream.
No splice points will be inserted in the video bitstream.
On VANC SCTE104 messages in VANC will trigger the insertion of splice points
On IP SCTE104 messages in IP will trigger the insertion of splice points
On GPI Splice point insertion will be triggered by GPI card inputs (see section 3.19)
3.19 How to Configure GPI Triggered Splicing
The GPI option card can be configured for triggered splicing by sending SCTE-104
messages to the encoders of the VCM cards fitted in the unit.
Note: To enable splicing, splice point insertion license (CE/SWO/DPI) is required.
The triggers are realized by closing and opening the general purpose input pins
(GPI pins 1-16) with a common GND; for the pin connections see Chapter 2,
Installing the Equipment). The configuration process has two parts:
• Setting up the GPI Card
• Setting up the VCMs
The connections between the configured pins of the GPI card and the destination
encoders are represented by virtual SCTE-104 channels. Each GPI card has 16
channels, labeled from ChannelA to ChannelP.
3.19.1 How to Set Up a GPI Card
To configure General Purpose Interface (GPI) input pins for splicing, proceed as
follows.
1. Select the Advanced Setup tab on the Device Configuration page on the GUI.
2. Expand Encoder > Slots > Slot n Data & GPI Card > GPI Input Pin n Setup
folders in the Advanced Video Processor Settings widget.
3. Set up the GPI input pins. For a detailed parameter list, see GPI Triggered
Splicing in Chapter 5, Web GUI Control.
4. Configure splicing options by expanding the appropriate GPI Input Pin n Setup
folder and selecting Splicing Setup. For a detailed parameter list, see GPI
Triggered Splicing in Chapter 5, Web GUI Control.
Note: A Splicing Setup folder is shown only if the GPI input pin mode has already
been set up in the respective GPI Input Pin n Setup folder.
