3.19.2 How to Set Up a VCM to Use GPI Inputs
To set up a Video Compression Module (VCM) for using GPI inputs, proceed as
follows:
1. From the web browser navigate to Device Configuration page and select the
Advanced Setup tab.
2. Expand the Encoder > Slots folders and the folder for the slot containing the
appropriate encoder card.
3. Select Video > Video 1 > Video > Main Video > Video Encoder > Splicing.
4. Set Splicing Control to On GPI. An SCTE-104 Input folder appears in the
settings tree and provides a list displaying all usable SCTE-104 channels. A
channel is usable if there is at least one GPI pin configured on the source end of
the channel (as described above).
5. Choose an input channel for the VCM encoder core. The configuration of the
VCM is now complete and the encoder waits for SCTE-104 messages on the
selected channel.
Combinations and Limitations
With the SCTE-104 channels a many-to-many relationship can be set up between
the GPI pins and the encoder cores of VCMs, as follows.
• More pins of the same GPI card can be configured to send messages to the
same set of encoder cores. This is achieved with selecting the same channel for
them on the GPI Input Pin Setup panel.
• More encoder cores (of the same VCM or different VCMs) can be configured to
get messages from the same set of pins of a GPI card. This is achieved by
selecting the same channel for them on the SCTE-104 Input > Encoder folder.
• Different GPI cards fitted in the same unit can not send messages to the same
encoder core, because one encoder core can only use one channel for
SCTE-104 input.
3.20 How to Use the Simplified View (Option)
3.20.1 Using the Simplified View
An optional ‘Simplified View’ is available for AVP 2000 and AVP 3000 units, aimed
at providing a single page, quick and easy-to-use, user interface for the day-to-day
operation of units. This extends the original simple Voyager Dashboard to include
support for ASI and IP outputs, and is not dependent on a Satellite Modulator card
being fitted.
