Locator Object

Locator objects contain information about the tuning space. Locator objects are generally used by the Network Provider filter to help a tuner find and acquire the transport stream. Applications do not use Locator objects except possibly for debugging purposes.

Method or Property NameDescription
CarrierFrequencySets or retrieves the carrier frequency(DecaHertz).
CloneCopies the Locator.
InnerFECSets or retrieves the inner FEC type.
InnerFECRateSets or retrieves the inner FEC rate.
ModulationSets or retrieves the modulation type.
OuterFECSets or retrieves the outer FEC type.
OuterFECRateSets or retrieves the outer FEC rate.
SymbolRateSets or retrieves the QPSK symbol rate.

Locator.CarrierFrequency Property

Remarks

This property is read-write.

Locator.InnerFEC Property

Locator Object

Inner FEC Type.

Syntax

Locator.InnerFEC

Remarks

This property is read-write.

Locator.InnerFECRate Property

Locator Object

Inner FEC Rate.

Syntax

Locator.InnerFECRate

Remarks

This property is read-write.

Locator.Modulation Property

Locator Object

Modulation Type.

Syntax

Locator.Modulation

Remarks

This property is read-write.

Locator.OuterFEC Property

Locator Object

Outer FEC Type.

Syntax

Locator.OuterFEC

Remarks

This property is read-write.

See Also

Locator.OuterFECRate Property

Locator Object

Outer FEC Rate.

Syntax

Locator.OuterFECRate

Remarks

This property is read-write.

See Also

Locator.SymbolRate Property

Locator Object

Sets or retrieves the QPSK symbol rate.

Syntax

Locator.SymbolRate

Remarks

This property is read-write. QPSK modulates symbols onto the RF signal. These symbols are detected by the demodulator and used to reconstruct a bit stream. QPSK allows the rate at which symbols are (de)modulated to be changed.
