In this paper, we present an event-on-demand (EoD)video adaptation system. The proposed system supports users in deciding their events of interest and considers network conditions to adapt video source by event selection and frame dropping.Firstly, events are detected by audio/video analysis and annotated by the description schemes (DSs)provided by MPEG-7 Multimedia Description Schemes (MDSs). And then, to achieve a generic adaptation solution, the adaptation is developed following MPEG-21 Digital Item Adaptation (DIA)framework. We look at early release of the MPEG-21 Reference Software on XML generation and develop our own system for EoD video adaptation in three steps:1) the event information is parsed from MPEG-7 annotation XML file together with bitstream to generate generic Bitstream Syntax Description (gBSD). 2) Users' preference, Network Characteristic and Adaptation QoS (AQoS) are considered for making adaptation decision. 3) adaptation engine automatically parses adaptation decisions and gBSD to achieve adaptation.Unlike most existing adaptation work, the system adapts video of events with interest according to users' preference. Implementation following MPEG-7 and MPEG-21 standards provides a generic video adaptation solution. gBSD based adaptation avoids complex video computation. 30 students from various departments were invited to test the system and their responses has been positive.
