Abstract
A local watch skew compensation device of the present invention is a client device which is synchronized with the other client device to provide a time-aware service including: a local time providing unit which supplies first local time data and second local time data in accordance with a local clock; a media scheduling unit which receives first media data and second media data from the other client device, schedules first playout time of the first media data using the first local time data, and schedules second playout time of the second media data using the second local time data; and a skew monitoring unit which requests global time data to a global time server when a difference between the first playout time and the second playout time exceeds a skew threshold value, and the first media data and the second media data are different types of media data.
