ADVANCES: Broadcast and video components meet reliability and stability requirements
New built-in driver support is being planned for Windows Longhorn. Support planned at this time includes a new class driver for USB video cameras.
Proposed requirements include the following:
 



• For any device that provides end-user capabilities for transfer of digital content, expose the device schema so that Windows can support seamless content transfer.
  
• The device and driver must ensure a minimum level of propagation and persistence of device or content metadata.
  
• The DirectX Video Acceleration (DirectX VA) API must be used if the hardware supports acceleration of MPEG-2 decode with motion compensation, iDCT, or VLD.
  
• Video that is interlaced must be de-interlaced using the DirectX VA and Direct3D 9 APIs for video.
  
• The components must be capable of rendering video with the Microsoft DirectShow Video Mixing Renderer using DirectX 9 Direct3D.
