Vosaic integrates the organization, retrieval and navigation of
continuous media into the World Wide Web. The Vosaic system includes a
Web browser, server, and Video Datagram Protocol (VDP) that adapt to network
load and client CPU conditions. Html extensions embed continuous or stored
real-time video and audio in Web documents. The extensions may specify the
starting and finishing frame of any clip of stored audio or video.
Frame-based video annotations embed dynamic hyperlinks displayed as visible
areas within the video data stream. Meta-information provides search
capabilities for video databases.
The newest B2.96 Release supports SGI and Sun (Solaris) browsers
and SGI, Sun and HP servers. Users may create hypervideo documents using
hyperlink editors and parse file generators included with the release.
Although a variety of compression algorithms work with Vosaic, the current
release supports MPEG-1 video and MPEG layer I or II sound. Software to create
appropriate MPEG sources are available though links on the Vosaic Web site.
Free binaries for Vosaic are available. Source is available at no charge to
researchers and developers who agree to the terms of the Vosaic developer's
licence.
The Vosaic documentation and software is available from the Web site
http://www.uiuc.edu/ph/www/vosaic.
Two papers, one old and one new, describe the architecture. Browsers may view
National Park and India footage as well as other demos at our site. Example
Web course materials with embedded video being developed for a Multimedia and
Operating System classes will also be available from time to time.
Vosaic was developed by the Systems Research Group of the Department of
Computer Science, University of Illinois at Urbana-Champaign. The Vosaic
team includes Professor Roy Campbell, Zhigang Chen and See-Mong Tan of
the University of Illinois, and Dong Xie of the University of Oslo, Norway.
