A reservation information table stores reservation information including a channel number, a recording start time, a recording end time, and an attribute related to each recording-reserved program. A group information table stores group information including a total capacity setting value for each group. An MPU selectively deletes a recorded program from recorded programs belonging to the same group when the total data amount of the recorded programs belonging to the group exceeds the corresponding total capacity setting value.
