Abstract: Disclosed is a program recommendation system and method which receive PSIP/SI and programming information on digital broadcasting and provide a program recommendation service to viewers in an EPG application. The system receives personal information in order to set information of each viewer, confirms the received PSIP/SI information, and generates watching information through a viewer watching TV, in a predetermined format. In addition, the system inputs the generated watching information to a database, converts watching information of each viewer which is stored in the database input unit into divided input patterns using a fuzzy membership function to analyze the input patterns, and extracts information on a program with a high degree of preference from the analyzed result. Furthermore the system outputs preference program information of each viewer on a screen in order to recommend a program.
