Introduction of Digital Video Libraries

• Functions of a digital video library
• Why digital video libraries?

4
Functions of a Digital Video Library

• Storage and play back of video resources
• Online access of video resources
• Search of useful information through the vast
  data collections
• Retrieval of the most relevant selections

5
Why Digital Video Libraries?

• Digital signal is easy to handle in computer
  world
• Multimedia content is more interesting
• For education, training, sports and entertainment
• dangerous chemical experiment
• record of surgery process
• An organized way of retrieval media contents

Introduction of Our Project

• Project aims
• How we do it?
• Works done by us

14
Project Aims

• Informedia as an existing model of DVL
• To develop our own version of digital video
  library
• Localization(Chinese video/scripts/queries/indexi
  ng)

15
How We Do It?

• Use Java Programming Language
• Use the Java Media Framework API
• Develop and test on the Windows platform

16
Why Use Java?

• JMF API support multimedia application
• Platform Independence
• Object-oriented language
• Easier to develop the GUI

17
What Can JMF Do?

• Enables multimedia content
• Supports a wide range of file formats(QuickTime,
  MPEG-1, MPEG-2, AVI, H.261, MIDI, AU, WAV, and
  AIFF)
• Support popular streaming media protocols

18
Works Done by Us

• A player which plays video clips and synchronous
  text scripts
• Mpeg videos clips of TV news
• Corresponding text scripts which synchronized
  with the video clips manually
