abstract = {More and more audio-visual information is available in
digital form, in various places around the world. Along with the
information, people appear that want to use it. Before one can use any
information, however, it will have to be located first. At the same
time, the increasing availability of potentially interesting material
makes this search harder. Currently, solutions exist that allow
searching for textual information. Many text-based search engines are
available on the World Wide Web, and they are among the most visited
sites - indicating they foresee a real demand. Identifying information
is, however, not possible for audio-visual content, as no generally
recognised description of this material exists. In general, it is not
possible to efficiently search the web for, say, a picture of ``the
Motorbike from Terminator II'', or to search a sequence where ``King
Lear congratulates his assistants on the night after the battle,'' or
to search for ``twenty minutes of video according to my preferences of
today''. In specific cases, solutions do exist. Multimedia databases on
the market today allow searching for pictures using characteristics
like colour, texture and information about the shape of objects in the
picture. One could envisage a similar example for audio, in which one
can whistle a melody to find a song.
The question of finding content is not restricted to database retrieval
applications; also in other areas similar questions exist. For
instance, there is an increasing amount of (digital) broadcast channels
available, and this makes it harder to select the broadcast channel
(radio or TV) that is potentially interesting.},
