IDigitalLocator Interface

The IDigitalLocator interface serves as the base interface for Locator objects that contain tuning information about the tuning space for a digital network. The base interface is never used directly. It is used only through derived interfaces such as IATSCLocator.

In addition to the methods inherited from ILocator, the IDigitalLocator interface exposes the following methods.

Method Description
get_InnerFEC Retrieves the type of inner forward error correction (FEC) that is used.
get_InnerFECRate Retrieves the inner FEC rate.
get_OuterFEC Retrieves the type of outer FEC that is used.
get_OuterFECRate Retrieves the outer FEC rate.
get_SymbolRate Retrieves the quadrature phase-shift keying (QPSK) symbol rate.
put_InnerFEC Specifies the type of inner FEC to use.
put_InnerFECRate Specifies the inner FEC rate.
put_OuterFEC Specifies the type of outer FEC to use.
put_OuterFECRate Specifies the outer FEC rate.
put_SymbolRate Specifies the QPSK symbol rate.
