Abstract: The production costs of broadcasting sport events that require
tracking moving objects are continuously increasing. Although those events are
very demanded by the audience, broadcasting organizations have economical
difficulties to afford them. For that reason, they are demanding the
development of new professional (software and hardware) equipments that lead to
a considerable reduction of the production costs. In this paper, we present a software system that takes into account these needs. This system allows a
technical director to indicate his/her interest about certain moving objects or
geographic areas in run-time. The system is in charge of selecting the cameras
that can provide the types of views requested on those interesting objects and
areas. So, it decreases the human effort needed to produce (create, edit and
distribute) audiovisual contents, giving at the same time the opportunity to
increase their quality. For this, the system provides a friendly interface to
specify requirements and obtain which monitoring video cameras attached to
moving or static objects fulfill them, along with a query processor to handle
those requests in a continuous and efficient way. We illustrate the feasibility
of our system in a specific scenario using real data of a traditional rowing
race in the Basque Country.
