SmarTV - a multi-person user´s behaviour analysis and program recommendation system with iTV

This paper presents a research in progress about a system for multiple person user´s behavior analysis and program recommendation for digital TV. Since it uses the spectator cell phone to identify the person, this research proposes an extension of the interactive TV interface to the user´s cell phone as well. The research explore two new approaches related to how TV is watched, using a Bluetooth cell phone and a Bluetooth set-top box connected to an digital TV network with return channel. The first approach is related to user´s behavior analysis and program recommendation. Supposing that every viewer has Bluetooth cell phone, each cell phone will identify every spectator to the set-top box wirelessly. The set-top box will inform the TV service provider the list of people who are in front of TV in real-time. Based on the history of programs watched by these people, it will be identified their profile and preferences. The second approach is the use of cell phone as a smart remote control and as an extension of the TV. The cell phone connected to the set-top box can be used by the interactive TV programs to show messages to the viewer or execute interactive applications.
