Modeling Television Schedules for Television Stream Structuring

www.lsis.org Abstract. TV stream structuring is very important for huge archives holders like the French National Institute, the BBC or the RAI, because it is the first necessary step to describe the various telecasts broadcast on various channels. It is also necessary for television ratings in order to isolate the telecasts that must be rated. One can think this structuring is a simple alignment of the TV guides on the stream itself. But TV guides present in average only 35 % of the telecasts that represent in average less than 18 hours by day. We propose in this article a method to predict TV schedules by modeling the past ones in order to boil down the television stream structuring problem to a simple alignment problem.
