Configuration
Audio Group Management
The Audio Group Management page (see Figure 12 on page 28 ) allows you
to perform the following functions:
• Pass/Delete Group all audio groups or delete one audio group,
• Insert or replace audio content in one available audio group,
• Turn off the
Insert/Replace Group
function,
• Set audio sample rate (
Bits per Sample
), and
• Set AES audio-to-video input synchronization mode:
• Synchronous – AES audio is in sync with SD video and will pass
status/control bits
• Asynchronous – AES audio is not in sync with input video and
status/control bits will not be passed, or
• Synchronous with matrix control – AES audio channel content is
controlled through a switching matrix on the Audio Matrix page
(see
Audio Matrix on page 29 ).
Note Replace and Delete functions are not available in Synchronous Matrix mode.
AES audio is inserted in available space only.
Click the
Apply
button to activate each selection.
Auto Insert places the AES/EBU input in the first available audio group. If
no group is empty, the Status line will report a warning for all groups.
The status reporting section of the display provides monitoring of:
• Audio groups present in the SD input,
• Status of the group insert/replace function, and
• Audio groups present in the SD output.
CAUTION When monitoring the status of the signal configuration, be aware that this
page is a static display and requires manual refresh. Changing SD input
upstream can cause changes to the 8920MUX output that will not be reported
until status refresh is activated. To refresh the status information, click on the
Audio Group Management link, the Refresh button, or an Apply button.
