Table 5.6 Splicing Set Up Options
Parameter Values Description
SCTE 104 Channel None, ChannelA to ChannelP
Virtual SCTE 104 channel used to route messages to
encoders. Different pins can share same channel. Different
encoders can share same channel.
GPI Pin Triggered
Polarity
Open, Closed (Default)
When the parameter is set to Open a message is sent when
the pin goes from Closed state to open state. When the
parameter is set to closed a message is sent when the pin
goes from open state to closed state. Splice latched mode
defines the trigger for the Out of network message.
Out Pre-roll 0, 4 to 100(s)
0 (default value) indicates immediate and a value less than 4
will be treated as immediate. A splice point is inserted at the
earliest possible opportunity. If a value is set for the pre-roll, a
splice point shall be inserted that many seconds after the GPI
pin contact change has been signalled.
Return Pre-roll 0, 4 to 100(s)
0 (default value) indicates immediate and a value less than 4
will be treated as immediate.
Return to Network Automatic
External Control
If set to Automatic a Return to network splice shall
automatically be inserted after the time set for the Splice
Duration has elapsed from when the Out of Network splice
was signalled.
Splice Duration 1 to 10000 (s)
Fixed Delay 0 to +1000 (ms) Added to both Out and Return pre-roll.
Splice ID Increment
Mode
For each Avail, For each Msg
Avail_Descriptor Off (Default), Present
If set to Present, the value in the Provider Avail Id is inserted
into the output SCTE 35 message
Provider Avail Id 0 to 424967295
Used as a reference to identify a specific Transport Stream
that the splice point is to be associated with.
GPI Input Pin State Read only.
5.4.4.4.5 Setting Up the VCM to Use GPI Inputs
Note: It is not possible to define the EventID , so all SCTE-35 messages will
contain the same EventID.
The example given here shows setting up a CE-x in slot 3.
To set Up the VCM to use GPI inputs, select the Advanced Setup tab on the
Device Configuration page on the GUI. Expand Encoder > Slots > Slot 3 > CE-x
> Video > Video 1 >
Video > Main Video > Video Encoder > Splicing folders in
the Advanced Video Processor Settings widget.
