This interface is implemented on the ATSCLocator object.
ILocator Method Name Description Clone Creates a copy of the Locator. get_CarrierFrequency Retrieves the frequency of the RF signal. get_InnerFEC Retrieves the type of inner forward error correction that is used. get_InnerFECRate Retrieves the inner FEC rate. get_Modulation Retrieves the modulation type. get_OuterFEC Retrieves the type of outer forward error correction that is used. get_OuterFECRate Sets the outer FEC rate. get_SymbolRate Gets the QPSK symbol rate. put_CarrierFrequency Sets the frequency of the RF signal. put_InnerFEC Sets the type of inner forward error correction that is used. put_InnerFECRate Sets the inner FEC rate. put_Modulation Sets the modulation type. put_OuterFEC Sets the type of inner forward error correction that is used. put_OuterFECRate Sets the outer FEC rate. put_SymbolRate Sets the QPSK symbol rate. IATSCLocator Method Name Description get_PhysicalChannel Retrieves the physical channel. put_PhysicalChannel Sets the physical channel. get_TSID Retrieves the transport stream ID. put_TSID Sets the transport stream ID.
Retrieves the physical channel.
Syntax
HRESULT get_PhysicalChannel( short* PhysicalChannel );
Parameters
- *PhysicalChannel
- [out, retval] Pointer to a variable of type short that receives the physical channel.
Return Value
Returns S_OK if successful. If the method fails, error information can be retrieved using the standard COM IErrorInfo interface.
Sets the physical channel.
Syntax
HRESULT put_PhysicalChannel( short PhysicalChannel );
Parameters
- PhysicalChannel
- [in] Variable of type short that specifies the physical channel.
Return Value
Returns S_OK if successful. If the method fails, error information can be retrieved using the standard COM IErrorInfo interface.
Retrieves the transport stream ID.
Syntax
HRESULT get_TSID( short* TSID );
Parameters
- *TSID
- [out, retval] Pointer to a variable of type short that receives the transport stream ID.
Return Value
Returns S_OK if successful. If the method fails, error information can be retrieved using the standard COM IErrorInfo interface.
Sets the transport stream ID.
Syntax
HRESULT put_TSID( short TSID );
Parameters
- TSID
- [in] Variable of type short that specifies the transport stream ID.
Return Value
Returns S_OK if successful. If the method fails, error information can be retrieved using the standard COM IErrorInfo interface.
