Location: Hersonissos, Greece
Presenter: Georg Güntner

Ingredients of the Demo
• Starting point: Imagine a mass media event with
– 23.000 athletes
– 14.000 officials
– 6.500 events
– 1.100 teams
– 12 parallel video live feeds
– 200 archival clips
• The vision: The production of a– real-time
– non-linear
– interactive
– multi-channel (5 channels)
video show in broadcasting quality
• Implementation– Development of a real-time production
support system
– “Intelligent Media Framework” based on semantic concepts deals with
• aggregation
• storage
• propagation
• filtering
• visualisation
of contextual information
– Annotation, detection and extraction of “knowledge”
– Recommendation and personalisation
• Performance indicators (field trial)– 3 x 2 x 5 x 5h = 150h of material
– 110.000 action messages sent
– 18.000 terms in 65 vocabularies
– 100.000 activities detected and stored
– 18.000 knowledge items created

Scientific and Technological Challenges
• Development of an intelligent content model
– Understanding of the LIVE domain (broadcasting, events, staging,
sports, …)
– Research on knowledge and
information requirements of the
LIVE staging process.
– Foundational grounding for
interactions between content
and knowledge
• Development of an intelligent media framework
– Understand standards of the domains (MPEG-7, NewsML, IPTC, …)
– Information integration for internal and external information sources
– Storage of and access to intelligent content objects
– Support the real-time character of the LIVE staging environment
