IAMTuner::get_CountryCode
The get_CountryCode method retrieves the country/region code that establishes the current channel-to-frequency mapping.
Syntax
HRESULT get_CountryCode( long *plCountryCode );
Parameters
plCountryCode
[out] Pointer to a variable that receives the country/region code currently in use by the TV Tuner filter.
Return Values
Returns an HRESULT value that depends on the implementation of the interface.
Remarks
The IAMTuner::put_CountryCode method determines which channel-to-frequency mapping table to use. This establishes the base frequencies for the given country/region. Use the IAMTVTuner::AutoTune method to determine the exact frequencies for specific regions.
Override the country/region code when a country/region wants to receive broadcast video from a different national source. For a list of country/region codes, see International Analog TV Tuning.
