Parameter Values Description
AFD Sustain
Maintain previously received AFD code
indefinitely
Maintain previously received AFD code for
period specified in Sustain Timeout, then drop to
default, i.e. code 1000
Maintain previously received AFD code for
period specified in Sustain Timeout, then switch
AFD off
Control what AFD code goes out when AFD is lost at input.
Indefinitely: Maintains previously received AFD code
indefinitely.
Default after Timeout: Maintains previously received AFD
code for period specified in Sustain Timeout, then drop to
default, i.e. code 1000.
Off after Timeout: Maintains previously received AFD code
for period specified in Sustain Timeout, then switch AFD
off.
AFD Sustain Timeout 0 to 5,10, 20, 50, 100, 120
Control how long in frames previous AFD code is
maintained. Zero means drop to default immediately on
loss.
Input Detection
The CE-HEVC VCM supports video input detection as described in Chapter 3,
Getting Started: How to Configure and Use Input Detection, with the exception of
"Auto Detect and Restore Saved Config".
5.5.3.2.2 Audio Stream Configuration
Audio Input
The following parameters are available on the Input 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>/Input menu on the front panel.
Table 5.42 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.
