Abstract. Video retrieval continues to be one of the most exciting research areas in the field of multimedia technology. With the advancement of sensing and tracking technologies it is possible to generate multiple personal video streams during events from different perspectives. This paper presents the first prototype of the MyView system that provides on-demand personalized video streams with multiple cameras and additional sensors. This system captures and stores video streams in an indoor office, extracts high-level events from local positioning system (LPS) tracking information, and provides on-demand video segments for high-level queries by mixing the multi-camera video streams for a stream of the best view.
