eAVDecDDOperationalMode enumeration

Specifies the compression control mode for a Dolby AC-3 or Dolby Enhanced AC-3 audio stream. This enumeration is used with the AVDecDDOperationalMode property.

Syntax

typedef enum eAVDecDDOperationalMode {
  eAVDecDDOperationalMode_NONE,
  eAVDecDDOperationalMode_LINE,
  eAVDecDDOperationalMode_RF,
  eAVDecDDOperationalMode_CUSTOM0,
  eAVDecDDOperationalMode_CUSTOM1,
  eAVDecDDOperationalMode_PORTABLE8,
  eAVDecDDOperationalMode_PORTABLE11,
  eAVDecDDOperationalMode_PORTABLE14
} ;

Constants

eAVDecDDOperationalMode_NONE No dynamic range control or dialogue normalization (dialnorm). This mode should be used only for signal tests.
eAVDecDDOperationalMode_LINE Line mode. Dialnorm is enabled with a reference level of -31 decibels full scale (dBFS). Dynamic range control is applied, and high-level/low-level scaling is enabled. To set the high-level scaling factor, set the AVDecDDDynamicRangeScaleHigh property. To set the low-level scaling factor, set the AVDecDDDynamicRangeScaleLow property.
eAVDecDDOperationalMode_RF RF mode. Dialnorm is enabled with a reference level of -20 dBFS. Dynamic range control is applied. High-level/low-level scaling is disabled; instead, the maximum dynamic range reduction is applied.
eAVDecDDOperationalMode_CUSTOM0 Custom mode 0 (analog dialnorm).
eAVDecDDOperationalMode_CUSTOM1 Custom mode 1 (digital dialnorm).
eAVDecDDOperationalMode_PORTABLE8 Dialnorm enabled, dialogue at -8dBFS. Dynamic range and compression used. High-level/low-level scaling is not allowed (always fully compressed).
eAVDecDDOperationalMode_PORTABLE11 Dialnorm enabled, dialogue at -11dBFS. Dynamic range and compression used. High-level/low-level scaling is not allowed (always fully compressed).
eAVDecDDOperationalMode_PORTABLE14 Dialnorm enabled, dialogue at -14dBFS. Dynamic range and compression used. High-level/low-level scaling is not allowed (always fully compressed).
