Abstract: An apparatus and method for allowing a plurality of playback devices to stream content of a master device simultaneously is provided. When the master device selects one of the playback devices as a reference device and multicasts a synchronization packet to the playback devices, the playback devices determine a synchronization time by comparing their own synchronization packet reception time with a synchronization packet reception time of the reference device. When the master device streams content, into which a time stamp is inserted based on the time of the reference device, the playback devices play the content based on the determined synchronization time. Therefore, even when the playback devices have different network latencies from the master device, the playback devices may accurately perform synchronized content playback.

Abstract: A terminal apparatus and a method for time synchronization are provided. The method includes setting a reference time for a time synchronization with another terminal apparatus, transmitting a sync signal comprising the set reference time to the other terminal apparatus, and if a response signal to the sync signal is received from the other terminal apparatus, performing the time synchronization with the other terminal apparatus based on a transmission time of the sync signal and a reception time of the response signal. Therefore, a terminal apparatus further simply and rapidly performs a time synchronization with another terminal apparatus.

Abstract: A method of receiving a packet by a receiving terminal is provided. The method includes receiving one or more packets including information about an event which belongs to a same kind of event from a transmitting terminal, and selecting at least one packet from among the received one or more packets based on time information of a certain point of time at the certain point of time.
