B11.1.4.1 Interoperability with operating system and Microsoft DirectShow
For any system capable of playing back a DVD-Video title, DVD playback must work with the latest released version of the Microsoft DirectShow Navigator/Splitter filter and other DirectShow test filters to ensure that it conforms to the input and output standards established by the Navigator/Splitter. In particular, it must work with the most recent versions of the following:
-
IDvdGraphBuilder
-
DirectShow DVD Navigator
-
DirectShow Overlay Mixer
The requirement to work with the DirectShow Navigator/Splitter filter is not intended to preclude the use of differentiating product features and enhancements.
If DVD-Video playback is implemented, the system must be capable of displaying subpicture data as well as providing closed-captioning support for all such data stored on the disc. This requires YUV offscreen overlay surface support.
Subpicture streams must be supported as defined in DVD Specification, Version 1.0, from Toshiba Corporation.
Alpha blending, or a driver-implemented emulation, is required for static menus.
All MPEG-2 decoders can accept an MPEG-2 Elementary Stream. The DVD decoder must correctly handle subpicture properties and other functions. The minidriver for the subpicture decoder must be able to:
-
Set the subpicture properties.
-
Turn the subpicture compositing on and off.
-
Set the highlight rect parameters.
