play the audio for advertisements.
Symptom: Audio is not played on certain advertisements.
Workaround: It is possible this behavior is caused by the
incorrect configuration of the Audio In/Out Block/Pass timer
settings. Verify the Audio settings in AIM.

In AIM Administration > Edit Device > Channel Name there
are four delay timers:
are four delay timers:
•
IN - Audio Block Timer (mS)
•
IN - Audio Pass Timer (mS)

OUT - Audio Pass Timer (mS)

OUT - Audio Block Timer (mS)
During the switching of the DCM, audio and video become out
of synch. AIM uses these delays to synchronize audio and
video.
of synch. AIM uses these delays to synchronize audio and
video.
A component track rule is defined in the DCM UI
"http://x.x.x.x/TSComponentSettings" for low delay service
with audio stream .
"http://x.x.x.x/TSComponentSettings" for low delay service
with audio stream .
AIM fetches this configured component track rule before
instructing the DCM to switch to the delayed feed. AIM
instructs the DCM to apply it to the output service and hence
blocks the audio stream. AIM also momentarily stops/sleeps
for "IN - Audio Block Timer" milliseconds. This will in effect
allow video to pass through for "IN - Audio Block Timer"
milliseconds but block the audio during this time. After "IN -
Audio Block Timer" milliseconds AIM uses the same
component rule again and allows the audio to pass by
applying the pass rule on output service. The AIM thread
again sleeps this time for "IN - Audio Pass Timer ". After "IN -
Audio Pass Timer " milliseconds . The DCM is instructed to set
the output to delayed feed. This completes the DCM switch to
delayed feed.

Third-Party Touch Panels

With Crestron devices, the channel control function which is used to pull up the
channel guide and act as a remote touch pad does not work. However, Crestron
provides a Guide function on their touch panel that allows users to scroll through
the guide.

The volume control function on the Crestron device only shows four (4) levels of
volume. Therefore, the device does not take advantage of the enhanced volume
granularity configurable through Cisco StadiumVision Director.

The ability to provide channel icons (in the channel lineup) to third-party devices
requires that the device have Ethernet connectivity.
