Structuration automatique de flux télévisuels

Abstract : In the setting of the legal deposit of French television, we design an automatic television stream structuring system.
We propose to model the program schedules with a statistical model based on a contextual Markov model and a regression tree. Such a model is justified by the stability of channels' program schedules. Once the model has been trained on past television schedules, the system is able to improve the completeness and the accuracy of program guides (like TV magazines or EPG). The merging of these two sources of information permits to predict all the most probable schedules for a given day and to predict the duration of each telecast.
Rules are then used to characterize the various transitions from a program genre to another by simple detections: logos, monochrome frames, silences. These rules, associated to the predicted program schedules, allow the system to detect the numerous transitions by performing locally detections.
