Access Grid Nodes

• Videoconferencing over broadband• Large-scale, multiple groups• Interactive collaborative meetings• High quality video/audio• Low latency• Multiple cameras, mikes, projectors, echo

cancellation• Collaborative support software and

middleware• http://www.accessgrid.org/

Access Grid Session

Other Video Annotation Tools

• IBM’s Video Annotation Tool• Ricoh MovieTool• ZGDV’s VIDETO• COALA’s LogCreator• INA/INRIA’s System – ISWC 2003• Microsoft’s Research Annotation System (MRAS), DTVI

(Distributed Tutored Video Instruction)

- all non-collaborative, asynchronous indexing and annotation systems

- MRAS, DTVI only support low frame rates

Project Phases• Collaborative MPEG-2 indexing, search, browse & retrieval• Objective descriptions

Metadata Application Profile – XML/MPEG-7 + Ontologies Incl. automatic shot detection (Mediaware SDK) Map to RDF

• Subjective annotations Annotea Annotation Protocol

• Flexibility – ontologies from different domains• Synchronous Collaborative Discussion, Annotation, Editing

T.120 (e.g. NetMeeting) vs .NET Remoting• Storage (relational DB vs. native XML DB vs. RDF Store)• Rights Clearance/Management – MPEG-21
