Comments

A tuning space is a set of information about the available channels and the channel to frequency mapping, which can identify a particular network provider or broadcast source. Multiple tuning spaces can be determined and stored for use in multiple areas.

This function gets the number of the current tuning space being used by the tuner.

To set the index of the current tuning space used by the tuner, call IltmfTVTuner::put_TuningSpace.

To get the most precise frequency for a particular channel, use IltmfTVTuner::AutoTune. Once the frequencies for all channels have been found using AutoTune, this information can be stored by calling IltmfTVTuner::StoreAutoTune.

For more detailed information, refer to the Microsoft documentation for IAMTuner::get_TuningSpace.
