IAMTuner::put_TuningSpace

The put_TuningSpace method sets a storage index for regional channel-to-frequency mappings.

Syntax

  HRESULT put_TuningSpace(
  long lTuningSpace
);

Parameters

lTuningSpace

[in] Value indicating the current locale.

Return Values

Returns an HRESULT value that depends on the implementation of the interface.

Remarks

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.

Requirements

Header: Declared in Strmif.h; include Dshow.h.

Library: Use Strmiids.lib.
