Abstract
A signage player includes: a time function configured to count an internal device time. The signage player also includes a time correction calculator configured to acquire a reference time from the outside, for example, an NTS server, at a timing determined in advance and synchronize the internal device time with the reference time; and a time corrector configured to calculate a time correction coefficient defined using a change rate of a time difference, an error change rate (Δ) between the reference time and the internal device time at a timing different from the timing determined in advance and calculate a corrected time acquired by correcting the internal device time using the time correction coefficient.
