Abstract
This paper describes applications built on the ViewStation, a
distributed multimedia system based on Unix workstations and a gigabit
per second local area network. A key tenet of the ViewStation project
is the delivery of media data not just to the desktop but all the way
to the application program. We have written applications that
directly process live video to provide more responsive human-computer
interaction. We have also developed applications to explore the
potential of media processing to support content-based retrieval of
pre-recorded television broadcasts. These applications perform
intelligent processing on video, as well as straightforward
presentation. They demonstrate the utility of network-based
multimedia systems that deliver audio and video data all the way to
the application. The network requirements of the applications are a
combination of bursty transfers and periodic packet-trains.
