Abstract
The present invention relates to a method of synchronizing playback of a digital content between connected devices, the method including: receiving a playback delay time list or a playback sync timestamp from a master device during a playback duty cycle; calculating a playback delay time correction amount by referring to the playback delay time list in order to synchronize playback between a plurality of connected devices including the master device; correcting a playback sync timestamp used in the playback synchronization according to the playback delay time correction amount; and playing a digital content according to the corrected playback sync timestamp, and the slave device applies a different playback delay time in consideration of the slave device's own state, so that the playback of the digital content may be synchronized between the devices connected through the network.
