This interface is a primary control interface of the media renderer for rendering DVD video. It is implemented by the DVD renderer and defines MPEG and DVD specific synchronization and control primitives that will be used by the DVD navigator during playback.

A pointer to an IDVDRenderer interface can be obtained by calling the IUnknown::QueryInterface method of a DVD-Video object and specifying the IID_IDVDRenderer reference identifier.

The IDVDRenderer interface has the following methods.

Method	Description
IDVDRenderer::RegisterSyncEvent	Binds an event handle to specific events in the DVD presentation.
IDVDRenderer::UnregisterSyncEvent	Stops the event notifications flow associated with a handle.
IDVDRenderer::Play	Starts typical decoding and rendering of a DVD stream.
IDVDRenderer::Abort	Aborts any decoding and rendering processes and flushes the internal data buffers.
IDVDRenderer::Pause	Pauses DVD rendering.
IDVDRenderer::Scan	Provides support for forward and reverse scan modes.
IDVDRenderer::Slow	Performs slow-motion forward and slow-motion reverse.
IDVDRenderer::Step	Causes the decoder to temporarily start playback to decode and display picture and then enter into paused state on return.
IDVDRenderer::SetAudioStreamType	Sets the audio decoder for a selected audio stream type.
IDVDRenderer::SetAudioStreamNumber	Sets the decoding stream number for audio.
IDVDRenderer::SetSubpictureStreamNumber	Sets the decoding stream number for a subpicture.
IDVDRenderer::SetPalette	Sets the subpicture palette.
IDVDRenderer::Highlight	Causes the decoder to display a highlight of the specified DVD button.
IDVDRenderer::GetHighlightedButton	Returns the currently highlighted button number.
IDVDRenderer::GetAudioCaps	Returns a bitmask identifying what audio capabilities are supported by the DVD-Video renderer.
IDVDRenderer::GetScanCaps	Returns a bitmask identifying which scan modes are supported by the DVD-Video renderer.
IDVDRenderer::SetAPS	Sets the Analog Protection Schema (APS).
IDVDRenderer::SetContentAspectRatio	Sets the content aspect ratio.
IDVDRenderer::SetDisplayAspectRatio	Sets the output display aspect ratio.
IDVDRenderer::SetAspectRatioMode	Sets the renderer choice of presentation.

The IDVDRenderer interface, like all COM interfaces, inherits the IUnknown interface methods. The IUnknown interface supports the following three methods:

• AddRef
• QueryInterface
• Release
