3.4.9.2 Status tab
This tab contains text boxes and status icons that indicate
the current status of the IRD-3111’s audio processing. Audio
1 and Audio 2 are shown in separate columns
• Audio presence (status icon)
• Audio PID
• Audio Type
• Sample Rate
• Output Mode
AC3 Audio Status (BSI)
• Service (bsmod)
• Coding Type (acmod)
• Bit Rate
• LFE presence (status icon)
• Dialnorm
3.4.10 The Audio Processing panel
The audio program inputs to the IRD-3111 are placed into
the four AES channels embedded in the IRD-3111 ASI
output.
Decode mode:
If the input audio programs have passed through the
decoder:
 the decoded outputs from Audio 1 (5.1 program which
is decoded to six discrete channels), are grouped into
three pairs of two channels (Left/Right; Center/LFE,
and Ls/Rs) and each pair is assigned to one AES.
 The decoded outputs from Audio 2 (stereo program)
are grouped as a pair (Left/Right) which is assigned to
one AES
Bypass Mode:
If the decoder has been bypassed (Decoder Operation
pulldown set to Pass-Through in the Audio Configuration
panel) for either of the programs:
 The non-decoded audio (AC3) will be inserted into
one of the output AES channels
 Only the AC3 element is available in this case; the
decoded program element pairs shown in the figure
do not exist
The default assignment is as shown in figure 3.18.
 Click the radio buttons to change the assignment
 A program element pair or AC3 program can be assigned to more than one AES if desired.
