get_InnerFECRetrieves the type of inner forward error correction that is used.
get_InnerFECRateRetrieves the inner FEC rate.
get_ModulationRetrieves the modulation type.
get_OuterFECRetrieves the type of outer forward error correction that is used.
get_OuterFECRateSets the outer FEC rate.
get_SymbolRateGets the QPSK symbol rate.
put_CarrierFrequencySets the frequency of the RF signal.
put_InnerFECSets the type of inner forward error correction that is used.
put_InnerFECRateSets the inner FEC rate.
put_ModulationSets the modulation type.
put_OuterFECSets the type of inner forward error correction that is used.
put_OuterFECRateSets the outer FEC rate.
put_SymbolRateSets the QPSK symbol rate.
IATSCLocator Method NameDescription
get_PhysicalChannelRetrieves the physical channel.
put_PhysicalChannelSets the physical channel.
get_TSIDRetrieves the transport stream ID.
put_TSIDSets the transport stream ID.

IATSCLocator::get_PhysicalChannel

IATSCLocator Interface

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.

IATSCLocator::put_PhysicalChannel

IATSCLocator 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.

IATSCLocator::get_TSID

IATSCLocator 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.

IATSCLocator::put_TSID

IATSCLocator 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.
