The Process

The Cataloging
DVDs are received from the vendor.
Cataloging info is collected and organized in an
Excel spreadsheet DVDs are sent to CIT for
encoding.

The Ripping
  • DVDs are copied to the hard drive and encoded in
    groups of ten using Handbrake.
  • Free Open Source
  • Archive quality .mp4
  • Archive stored for future revisions to project.

10
The Ripping
This is the most time consuming aspect of the
process mostly due to dead time between DVDs.
MPEG-4 chosen as archive format to facilitate
ease of future encoding.
11
The Encoding
  • Archives are encodedfor delivery usingSorenson
    Squeeze
  • Streaming
  • 300k for off-campus
  • 500k for on-campus
  • Download
  • VBR suitable for viewing full screen in class

12
The Encoding
Watch Folder allows us to automatically process
files after they are ripped.
MPEG-4 Video with AAC Audio 300k - 480x360,
256k,15fps, 32k audio 500k - 512x384, 512k,
30fps, 64k audioVBR - 512x384, 1Mb, 30fps, 128k
audioArchive - 720x480, 2Mb, 30fps, 256k audio
13
The Ripping Encoding Hardware
  • Dual 2.3 Ghz G5 from Apple
  • Wide range of video tools available for OS X.
  • Eventually 3 dedicated machines for this task.
  • Processors and HD space most important criteria
    for any purchase.

The Cataloging Part II
Upload files to the server Updates to catalogs
made from spreadsheet
  • MDID
  • Restricts access to JMU community and manages
    rights to individual files.

LEO JMUs online library catalog. This ties the
physical resources with the online version.
Promotes service.
15
The Streaming Server
  • Apple Xserve with Xraid
  • Dual 1.8 Ghz G5
  • 1.1 TB of storage in RAID 5
  • Expandable to 4.6 TB by just adding modules
  • Chosen for price and ease of administration.
  • 919 Titles (460GB) and 453 Archives (314GB)

16
The Viewer
  • MDID determines access to individual files.
  • Users must use Quicktime player to view streams.
