a location-aware system for monitoring sport events
Nowadays it is widely recognized the need of developing a new generation of professional equipment for broadcasting that allows a considerable reduction of productions costs in different scenarios. We consider mobile multimedia scenarios where the incorporation of last generation hardware and the development of new software should allow: 1) to decrease the needs of human resources to produce (create, edit, and distribute) audiovisual content; and 2) to increase the richness of the broadcasted product. In this paper, we propose a software system that helps technical directors to deal with many motorized videocameras attached to moving or static objects in wireless environments. We use mobile agents to carry out the processing tasks wherever they are needed. Thus, agents are in charge of tracking the location of interesting static or moving objects and the (current and possible) focus range of all the cameras, as well as of refreshing the query answers efficiently and continuously. We present a traditional rowing race in the Basque Country as motivating scenario, where technical directors may indicate interesting objects or geographic areas in run-time and the system is in charge of selecting the best shots from the cameras in the scenario.
