[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

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

Syntax

HRESULT put_TuningSpace(
  [in] long lTuningSpace
);

Parameters

[in] lTuningSpace

Value indicating the current locale.

Return value

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.
