TV stream structuring consists in detecting precisely the first and the last frames of all the programs and the breaks (commercials, trailers, station identification, bumpers) of a given stream and then in annotating all these segments with metadata. Usually, breaks are broadcasted several times during a stream. Thus, the detection of these repetitions can be considered as a key tool for stream structuring. After the detection stage, a classification method is applied to separate the repetitions in programs and breaks. In their turn, breaks repetitions are then used to classify the segments which appear only once in the stream. Finally, the stream is aligned with an electronic program guide (EPG), in order to annotate the programs. Our experiments have been applied on a 22-day long TV stream, and results show the efficiency of the proposed method in TV stream structuring.
