TV stream structuring consists primarily in breaking down the stream into advertisings, telecasts and time slots. These time slots and telecasts need then to be structured. This paper focuses on the structuring of one of the dayparts: the morning drive. The challenge resides in these morning drives' components heterogeneity under a same theme and branding: music, weather, news, sets, advertisings and reports are mixed. Classical structuring methods concern videos with homogeneous components, like sport games, and need few features. We propose here a solution to time slots structuring by modeling morning drives' structure in order to decrease the number of needed detections and to decrease the number of false alarms. Good results are obtained since 97% of the segments are correctly retrieved and since the accuracy of the retrieved structure is approximately 5 seconds.
