Ericsson AVP 4000, Reference Manual, Page: 234 / 422

Web GUI Control
5-50 1/1553-FGC 101 1790 Uen Y
Parameter Values Description
Maximum Boost 0 to 10 dB This control determines the maximum amount of gain that
the LTLC algorithm can apply. This is to prevent over
adjustment which can lead to unwanted audio artifacts.
This only applies when the operating mode is “M
ALC + LTLC”
Maximum Attenuation 0 to 10 dB This control determines the maximum amount of
attenuation that the ALC and the LTLC algorithm can
apply. This is to prevent over adjustment which can lead to
unwanted audio artifacts
Preset Subtle, Standard, Strong
The available options are
Subtle
,
Standard
and
Strong
.
This setting controls the aggressiveness of the corrections
performed by the Short Term ALC algorithm. It controls
how quickly the correction takes place and the strength of
the correction
Reset Statistics True, false This can be used to reset the statistics that have been
collected in the Audio Algorithm. Due to the slower update
nature of the web interface the apparent change would be
to the measurement of the Integrated Loudness only
The reference target
level
Line out mode RF mode; Portable mode -14dB;
Portable mode -1dB; Portable mode -8dB
Sets the reference target level for downstream decoders.
Override dialnorm
metadata
Off, on
For Dolby encoding, the dialnorm parameter can be
overridden with the Target Level. This is recommended
practise.
Audio Component
The parameters listed in the table below are available on the
Component
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
Output/<output name>/Transport Stream ID: <n>/Service List/<service
name>/Component List/<component name> menu on the front panel.
Table 5.25 Audio Component Parameters
Parameter Values Description
PID 16 to 8190 Sets the packet identifier associated with the component.
Bit Rate Weighting Fixed Specifies the weight associated to the component in the
Bit Rate Tracking algorithm. For audio stream, this is Fixed
and read only.
Exclude from PMT False If set to True, this component will not be referenced in the
PMT, and its bit rate is excluded from bit rate calculations.
Source PID Monitoring None; Monitor; Monitor & Redundancy Priority 1 ETR290 monitoring on this PID can be enabled,
and can be set to cause a redundancy switch to a spare
device if in a system controlled by Ericsson control
software. Only used for IP sources.
