Broadcast networks spend a large amount of resources in covering many events and many different types of audiences. However, it is not reasonable for them to cover smaller events or audiences, for which the cost would be greater than the potential benefits. For that rea- son, it is interesting to design systems that could automatically generate summaries, or personalized news shows for these smaller events or audi- ences. GENA was designed in collaboration with Televisio ? de Catalunya (the public Catalan broadcaster) precisely to address this problem. This paper describes GENA, and the techniques that were designed to address the complexities of the problem of generating audio-visual narrative. We also present an experimental evaluation in the domain of sports.}, author = {Santiago Onta{\~n}{\'o}n and Josep Lluis Arcos and Josep Puyol-Gruart and Eusebio Carasusan and Daniel Giribet and David de la Cruz and Ismel Brito and Carlos L{\'o}pez de Toro}, editor = {B.
