A apparatus for processing EPG information that EPG (Electronic Program Guide) information can be read prior to display independently of an operation by an input device. The EPG information processing apparatus controls the amount of EPG information stored in a database prior to display so that the speed of acquiring EPG information and the speed of supplying EPG information indicating the frequency of using an acquired electronic program guide are kept in a predetermined relation. In response to a direction for updating an on-display electronic program guide, the EPG processing apparatus supplies new EPG information, and stores another piece of EPG information associated with the EPG information in the database prior to next display. The amount of information stored in the database in advance is decided so that the acquiring speed and supplying speed can be kept in a predetermined relation. Therefore, the amount of information stored in advance is raised with increase in the frequency of using an electronic program guide in correlation with the acquired supplying speed, and the amount of information stored in advance is decreased with decrease in the using frequency.
