IScanningTunerEx::SetScanSignalTypeFilter

This topic applies to Windows Vista.

Not implemented in this release.

The SetScanSignalTypeFilter method specifies the type of signal to scan for. Applications can optionally call this method before calling PerformExhaustiveScan, to filter the signal types that the tuner will search for.

Syntax

  HRESULT SetScanSignalTypeFilter(
    long 
  ScanModulationTypes
  ,
    long 
  AnalogVideoStandard

  );

Parameters

Specifies the modulation types, as a bitwise OR of flags from the ScanModulationTypes enumeration. If the value is 0xFFFFFFFF, the tuner does not filter out any specific modulation types.

AnalogVideoStandard

Specifies the analog standards, as a bitwise OR of flags from the AnalogVideoStandard enumeration. If the value is 0xFFFFFFFF, the tuner does not filter out any specific analog video standards.
