Configuring the Channel Options
Setting the SCTE-104 access level
The SSP-3801 card supports SCTE-104 splice requests with the following
splice_insert_types:
• spliceStart_normal: determines the pre-roll period in milliseconds, which defines the
delay between receiving the message and putting the event on air.
• splice_cancel: cancels a scheduled Take Next initiated by a spliceStart_normal
command.
• spliceStart_immediate: attempts to take the next event to air as quickly as possible
(non-deterministic).
In all cases, the event that is to be taken to air should already be on hold in a cued or
commit state. Typically, the schedule should contain an SCTE-104 triggerable manual event
that will hold at the on-air threshold until one of the SCTE-104 splice request is received. For
more information on SCTE-104, refer to the “SCTE 104 2014 Automation System to
Compression System Communications Applications Program Interface (API)” available from
http://www.scte.org.
To configure how the SSP-3801 card will treat SCTE-104 messages:
1 Select Channel Configuration > SCTE-104. The SCTE-104 Access page opens.
Fig. 2-5: SCTE-104 page
2 Select the Act upon SCTE-104 splice request triggers checkbox to execute and log
received SCTE-104 splice messages. Clear the checkbox to ignore and not log the splice
messages.
3 Select the Block all SCTE-104 messages from being passed-through checkbox to
prevent all SCTE-104 messages from reaching the card and from being logged. Clear
the checkbox to allow SCTE-104 messages to reach the card.
4 Click Save when done.
IMPORTANT:
When the SSP-3801 card is registered with GV STRATUS Playout, then GV
STRATUS Playout overwrites any Channel Configuration changes made
through the card’s web interface any time it updates the card with its own
changes.
