Understanding the Media Xcelerator™ (Optional)
The Dell Media Xcelerator™ is an internal USB 2.0 bus-powered device that 
increases the speed and performance of MPEG transcoding and transrating 
for various 3rd party applications supporting the Sonic DVD engine.
The Xcelerator™ device enables faster format conversion and facilitates 
resolution changes to MPEG-2 and DVD video streams. The device will allow 
MPEG2 or DVD based format conversions and fit to disk operations to be 
completed in significantly less time. A built-in, dedicated processor ensures 
significantly improved system availability and speed. The Xcelerator also 
supports MPEG-2 and DVD format stream conversion to low bit-rate MPEG-4 
formats for portable video devices.
Features supported include:
• Improved system availability through CPU offloading to Xcelerator.
• Quicker DVD creation with improved fit to disk capability.
• Transcode High Definition MPEG-2 video clips to MPEG-2 or MPEG-4 
standard definition 
• Faster conversions of movies into PC or PMP formats
• Transrate MPEG-2 video clips to a lower bit rate to fit onto a DVD, CD, or 
other media
• Higher transcoded video quality at similar bit rates
