A television broadcast received by a television broadcast receiving device is recorded as a recording file, and a central control device identifies specific recording portions (for example, commercial portions) within the recording file, and then calculates the remaining playback time (the total remaining time without the specific recording portions) that is the playback time of the recording file after the playback position minus the total time for the specific recording portions after the playback position, and displays information according to the total remaining time without the specific recording portions.
