The put_TuningSpace method sets a storage index for regional channel-to-frequency mappings.
HRESULT put_TuningSpace( long lTuningSpace );
[in] Value indicating the current locale.
Returns an HRESULT value that depends on the implementation of the interface.
As TV tuners move into portable systems, you must retain locale-specific mappings of available channels and their actual frequencies. Formulating different lTuningSpace values for each locale provides a way of switching the channel-to-frequency mappings when moving from region to region.
