Table 5.98 Audio Input Parameters
Parameter Values Description
Input Format
Uncompressed (LPCM), MPEG Layer II, Dolby
Digital, Dolby E, AAC
Sets the input format used by the audio encoder.
Input Source
Off, Mute, Test Tone, Embedded 1 to 8, Input 1 -
4
Sets the source used by the audio encoder. No input is fed
to the encoder if Off is selected. Mute mutes the incoming
audio and encodes silence. Test Tone encodes an 1 kHz
test tone, Embedded 1 to 8 sets the source to an SDI
embedded audio stream. Input 1-4 are for the digital
inputs.
Output On Audio Loss No PID, Silence
Specifies the action to take when input is Lost. No PID is
for dropping the audio PID from the stream, Silence is for
encode silence.
NOTE: When No PID is selected, the reference to the PID
is not removed from the Program Map Table, so a
Transport Stream analyzer will indicate a ghost PID in the
output Transport Stream.
Source Switchout
Off, Mute, Test Tone, Embedded 1 to 8, Input 1 -
4
Specifies which input to output to the reference output on
the 15-way D-type audio connector.
Audio Encoding
The following parameters are available on the Encode tab of the Properties widget on the
Service Configuration page when an audio component is selected in the Outputs widget.
The same parameters can be accessed through the Advanced/CE-HEVC/Audio
Module/Audio <n>/Encode menu on the front panel.
Table 5.99 Audio Encoding Standards
Parameter Options Description
Coding Standard

HE-AAC
HE-AAC or HE-AAC v2encoding, requires CE/SWO/AAC
license.
Pass-thru Pass-thru of the input
Audio Description Service
MPEG-1 Layer II encode of a mono audio track that
describes action in the video plus a control track.

1+1 (L/Ch1, R/Ch2), 2/0, 2/0 (Joint), Phase
Aligned Audio (6 Cannels), Phase Aligned Audio
(8 Cannels)
Specifies what channel configuration to use for encoding.
Embedded PCR On, Off
Controls whether PCR is to be embedded in the audio
PES.
