T
hese tools will continue to be tested
and modified over time. In addition, a
variety of other tools as well as programs
for managing files and surrogates and the
MySQL database and PHP code to link
the Open Video interface to the backend
have been developed. Over the long term,
we hope to create an integrated and open
source toolkit that can be shared by other
research groups.
SUMMARY
I
n this article, we have given a brief
overview of the current achievements in
our NSF-funded Open Video Project.We
have about 2000 individual video segments
in our collection that have been donated
by various contributors.We have tested
and evaluated several different types of
video surrogates individually and tried to
integrate them together to create an `Agile
View' user interface.We have also devel-
oped a set of tools to help with catalogu-
ing and indexing videos, generating video
surrogates and supporting video sharing
and collaboration.We will continue our
work in these areas and hope to communi-
cate and collaborate with other digital
video archive groups.

between accuracy and efficiency is
achieved by adopting a semi-automatic
authorisation approach. Semantic informa-
tion such as video annotation is integrated
with the visual information under an
XML schema. It can act as a semi-auto-
matic tool to generate storyboard and fast-
forward surrogates.
V
IVO
(Video Indexing and
Visualization Organizer) [Yang et al.,
2003a] is a tool we developed to help digi-
tal video librarians to input, edit and man-
age video metadata elements on different
levels. It uses a hierarchical tree to organise
the multiple-level (e.g. video, segment and
frame) video structure (see Figure 3). Each
video level has its own textual metadata
and visual surrogate. Librarians can cata-
logue and index videos at each level with-
out losing context.
T
he ISEE (Interactive Shared
Educational Environment) [Mu et al.,
2003a] is a real-time collaborative multi-
media distance learning tool suitable for
heterogeneous network connections (see
