IDVBSLocator2 Interface

[This documentation is preliminary and is subject to change.]

Provides information to enable a tuner to acquire a Digital Video Broadcasting-Satellite (DVB-S) transmission. This interface extends the capabilities in the IDVBSLocator interface to support the DVB-S, Second Generation (DVB-S2) specification, the Digital Satellite Equipment Control (DiSEqC) protocol, and low-noise block converters (LNBs).

Methods

The IDVBSLocator2 interface inherits from IDVBSLocator.

In addition, IDVBSLocator2 defines the following methods.

Method Description

get_DiseqLNBSource

Gets the selected DiSEqC LNB source.

put_DiseqLNBSource

Sets the selected DiSEqC LNB source.

get_LocalOscillatorOverrideLow

Gets the low oscillator frequency of the DVB system.

put_LocalOscillatorOverrideLow

Sets the low oscillator frequency of the DVB System.

get_LocalOscillatorOverrideHigh

Gets the high oscillator frequency of the DVB system.

put_LocalOscillatorOverrideHigh

Sets the high oscillator frequency of the DVB System.

get_LocalLNBSwitchOverride

Gets the LNB switch frequency of the DVB system.

put_LocalLNBSwitchOverride

Sets the LNB switch frequency of the DVB system.

get_LocalSpectralInversionOverride

Gets the state of spectral inversion on the DVB-S2 signal.

put_LocalSpectralInversionOverride

Gets the state of spectral inversion on the DVB-S2 signal.

get_SignalRollOff

Gets the roll-off factor for the DVB-S2 signal.

put_SignalRollOff

Sets the roll-off property for the DVB-S2 signal.

get_SignalPilot

Gets the pilot mode of the DVB-S2 signal.

put_SignalPilot

Sets the pilot mode of the DVB-S2 signal.
