Verifying Set-Top Performance
Use the following criteria when you verify set-top performance:
The one-line EAS display starts in the upper left corner of the Society of Motion
Picture and Television Engineering (SMPTE) safe title area of the screen.
The EAS line of text, or ticker, scrolls from right to left at a rapid rate. The text
appears for the amount of time that is set in the configuration data of the motion
delay setting.
The ticker display is 83% opaque over video and 100% opaque over any graphics
such as the IPG, General Settings, and music.
If the Interactive Program Guide (IPG) is active, the captured video in the upper
right corner of the screen freezes while the ticker displays.
If the EAS is not Force Tuned, the ticker display remains while the resident
application (ResApp) operates normally. The ticker appears over the General
Settings menu, music channels, PIN entry screens, and other IPG screens.
The EAS audio file always overrides analog and digital audio and internally
generated sounds.
The text display, or ticker, and audio playback repeat as long as necessary to fill
the duration. If the delay time is greater than 5 seconds, the program audio is
heard during the delay time between repeats.
The EAS suspends operation when one of the following occurs:
-
The time reaches the origination time plus the duration received in the EAS
request pass-through message.
Note: Origination time plus duration does not apply to Force Tuned
Note: Origination time plus duration does not apply to Force Tuned
messages.
-
The set-top receives an EAS Termination (EAT) pass-through message.
-
If the EAS message is active when a new EAS message is received, the entire
new message including the audio file, if applicable, downloads and the old
message suspends operation.
-
If the EAS message causes Force Turning, other message types are ignored,
except for the EAT message.
