IDVBTLocator Interface

  • Article

The IDVBTLocator interface is implemented on the DVBTLocator object. It provides methods to enable a tuner to acquire a terrestrial DVB (DVB-T) transport stream. The data types are defined in Bdatypes.h. Locator data is meant for consumption by the BDA hardware drivers. Applications do not need to interpret any of this data except perhaps for some debugging purposes.

Locators can be created dynamically when the tune request is created, by a loader that has access to the necessary information about the tuning space, or a default locator can be installed when the tuning space is first installed, and the loader can use the default locator when creating tune requests. Applications do not need to use any of the Locator interfaces unless they are creating tune requests. All Locator objects also support IPersistPropertyBag.

Methods

The IDVBTLocator interface inherits from IDigitalLocator.

In addition, IDVBTLocator defines the following methods.

Method Description

get_Bandwidth

Retrieves the bandwidth of the frequency in megahertz, usually 7 or 8.

get_Guard

Retrieves the guard interval.

get_HAlpha

Retrieves the hierarchy alpha.

get_LPInnerFEC

Retrieves the inner FEC type of the low-priority stream.

get_LPInnerFECRate

Retrieves the inner FEC rate of the low-priority stream.

get_Mode

Receives the transmission mode.

get_OtherFrequencyInUse

Indicates whether the frequency is being used by another DVB-T broadcaster.

put_Bandwidth

Sets the bandwidth of the frequency in megahertz, usually 7 or 8.

put_Guard

put_LPInnerFECRate

Sets the inner FEC rate of the low-priority stream.

put_Mode

Sets the transmission mode.

put_OtherFrequencyInUse

Specifies whether the frequency is being used by another DVB-T broadcaster.
