194. DVD-Video playback, if present, meets DVD-Video playback requirements

Servers that provide DVD drives only as storage devices do not have to include the additional capabilities required for DVD-Video playback on a local display device. Only servers that provide the specific feature of DVD-Video playback to the local server display must meet the DVD-Video playback requirements specified in these guidelines.

• 
  DVD decoder driver correctly handles media types, time discontinuity, and decode-rate adjustment. This requirement specifies that the vendor-supplied minidrivers for DVD, MPEG 2, and AC 3 decoders have the following capabilities:
  
• 
  Use correct media types. This includes validating all format block fields on connection and on every IPin::QueryAccept message.
  
• 
  Query for IMediaSample2 on every received media sample to test for a time discontinuity bit. It is also acceptable to query on every video/audio frame to reduce CPU overhead.
  
• 
  Adjust decode rate in response to IPin::NewSegment() calls for video and subpicture.
  
• 
  DVD decoder supports subpicture compositing and closed captioning. 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 surface support, as defined later in this list.
  

• 
  Subpicture decoder correctly handles subpicture properties and other functions. The minidriver for the subpicture decoder must be able to correctly handle the following:
  
• 
  Set the subpicture property
  
• 
  Turn subpicture compositing on and off
  
• 
  Set the highlight rect parameters
  

• 
  System supports seamless DVD Video 1.0 navigation. This requirement includes menu navigation and video selection, and language and subpicture track selection to support the user’s ability to navigate DVD Video discs. Test sources include, but are not limited to, the following:
  
• 
  Matsushita Electronics Incorporated (MEI) test disc
  
• 
  Joe Kane Productions Video Essentials disc
  
• 
  Microsoft test disc
  
• 
  MPEG 2 playback provides high-quality video output. MPEG 2 solutions must provide high-quality video display output, as defined by the following:
  
• 
  Smooth frame delivery, with all video fields and frames from the MPEG source decoded.
  
• 
  Audio and video synchronized to within one and a half video frames, with synchronization not allowed to drift out over time.
  
• 
  No tearing—provide proper video buffering, such as double buffering.
  
• 
  Correct display of multiple-aspect ratio content. The material should be displayed according to the aspect ratio information in the MPEG header.
  

• 
  Graphics adapter supports DVD movie playback features. Any system with a DVD drive that includes the ability to play back MPEG 2 data streams must meet the requirements listed here. However, this requirement does not apply for systems that include DVD drive for storage purposes but do not include DVD Video playback software. The following capabilities are required for solutions that use either hardware or software MPEG 2 decoders:
  
• 
  Up and down scaling with bilinear interpolation
  

• 
  YUV 4:2:2 and 4:2:0 planar offscreen surface support
  
• 
  VGA destination color keying for video rectangle
  
• 
  AGP or PCI bus mastering
