OPT-SW-PHXEAS-MS (V1.1) EAS OPTION (+EAS) MANUAL SUPPLEMENT
5
+EAS Controls and Examples
Table 1 individually lists and describes the EAS controls available using
DashBoard™ for cards/devices equipped with the
+EAS
option.
Table 1 +EAS Option Control List and Descriptions
Provides master controls that direct the playout of all EAS
insertions, including triggering mode, as well as and crawl speed
and looping. Also provides an event log.
EAS > General Setup
• EAS State (Status)
Displays status of crawl activity. When crawl is not currently being inserted,
shows “Crawl Stopped”.
• EAS Triggering Mode Select Selects how EAS is played out when a trigger is received as follows:
• Disabled – EAS is never played out regardless of received triggering. In the
Event Setup table, no EAS-related events will be generated or triggered
upon.
• Event Triggered – EAS text string will be received and buffered, but will be
played out (inserted into key) only when an accompanying trigger is
received.
This is useful in cases where some time is required to acquire the entire text
string before playout can be executed. For external systems where this is a
concern, a GPI signal is typically provided as a “ready-go” signal to activate
the crawl. (See Event Setup Controls, p. 10 for an example of GPI triggering
setup.)
• Immediate – EAS text string will start playout as soon as the complete
message text is received.
Note: The Crawl Start Delay control described below can be used to buffer
the playout start for systems where the separate GPI trigger
described above is not available, but delay may still be desired.
• Crawl Start Delay and Loop Control
• Crawl Start Delay sets the delay (in seconds) from when text is first
received to when the playout insertion is executed.
• Crawl Loop Count sets the number of times (from 1 to 3) the active crawl
insertion will be repeated for a given message.
Note: For a given EAS message/event, an automated or external stop
control is not necessary to stop the crawl. Crawl key insertion and
scroll will stop and normal video will resume when the Crawl Loop
Count is exhausted.
