Abstract :
This paper proposes a restructuring method for data via digital video satellite broadcasting systems. The research is motivated by development of the EPG (electronic television program guide) system for browsing through the content of a few hundred channels. It is not possible for users to check each piece of data all the time. We propose a new approach to reorganize the EPG data for retrieving the desired television program information instead of a system-defined EPG
