Abstract

In optical disc apparatus, time data recorded on an optical disc is read out, and a read-out time at this timing is compared with an immediately previous display time. Only when the read-out time is within a time range that is obtained by adding a predetermined time to the immediately previous display time, the display time is updated and the updated display time is output. When the read-out time is outside the time range, the display time is not updated and the immediately previous display time continues to be output. Even in case where the read-out time is outside the predetermined time range, when read-out times are stored a predetermined number of times and time continuity exists in the read-out times, the display time is updated to the latest one of the plural stored read-out times, and the updated display time is output.
