PROBLEM TO BE SOLVED: To solve the problem that the optimization of the combination of stored programs is not taken into consideration and a program set for maximizing the predicted satisfaction of a user can not be stored. SOLUTION: This system is provided with a preference learning means 2 for learning program preference from the viewing action of the user, a preference degree prediction means 4 for predicting the preference degree of the user from program information for respective programs and a storage schedule means 5 for obtaining a solution for maximizing a general predicted satisfaction within schedule object time within a limited storage capacity at the time of deciding the program to be stored or the program to be erased. By the constitution, a device for effectively using the storage capacity of a broadcasting storage device, automatically storing the programs suitable for the user and presenting them to the user is realized. By using a random access medium such as a magnetic tape or an HDD and mounting the storage device of the various kinds of data supplied by television, radio or the Internet, etc., the efficient automatic storage of the various kinds of the programs or information is realized.
