Table 5.27 Audio Component Parameters
Parameter Values Description
PID 32 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 from an IP input
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. Not supported in this release.
Dolby Metadata Presets
Four custom Dolby Metadata Presets can be configured in the Advanced Setup tab of the
Device Configuration page. To set the preset options, in the Advanced Video Processor
Settings drill down to Encoder > Slots > Slot <n> - CE-a >CE-a > Audio Module > Dolby
Metadata Presets, and select the preset you want to modify. Alternatively, the settings can
be reached through the front panel under Advanced/CE-a/Audio Module/Dolby Metadata
Presets. Any of these presets can then be applied to any audio channel encoding audio in
the Dolby Digital format. The table below lists the parameters for each preset.
