IAMTimecodeDisplay Interface

The IAMTimecodeDisplay interface controls an external SMPTE/MIDI timecode display device.

DirectShow currently does not provide any filters that implement this interface. Third parties should implement this interface on any filter that controls the timecode display of an external timecode reader or generator. Timecode readers or generators can be built into a VCR or can be separate external devices.

This interface is not intended for rendering in a Microsoft® DirectShow® filter graph; it is purely for use on external device displays.

Hardware Requirements

See the IAMExtTransport interface for hardware requirements.

In addition to the methods inherited from IUnknown, the IAMTimecodeDisplay interface exposes the following methods.

Method Description
GetTCDisplayEnable Determines whether an external device's timecode character generator output is enabled or disabled.
SetTCDisplayEnable Enables or disables an external device's timecode character output generator.
GetTCDisplay Retrieves current settings of the timecode character generator output.
SetTCDisplay Sets the timecode character generator output characteristics.
