An Adaptive Cartography of DTV Programs

Overview & Synopsis

With the development of information technologies and more precisely, the so-called digital convergence, the number of digital TV (DTV) programs available on any kind of DTV receiver (satellite, cable, terrestrial or IP) has increased dramatically. This has made the task of selecting a DTV program very complicated and time consuming. This paper proposes an intelligent graphical user interface (GUI) tool that gives a new appearance to the on-air and recorded DTV contents in order to enable DTV viewers to, quickly and in a user-friendly manner, select a program. The GUI tool is based on a synthetic cartography of DTV programs in which the shape generated reflects the DTV viewers' preferences over a period of time. These preferences are obtained by using any method for program clustering and recommendation. Results are demonstrated on the task of recommending programs in the context of the French terrestrial DTV by using a content-based approach.
