16. A peer-to-peer (P2P) network system comprising:
-
a streaming server which groups transmission unit packets of a data stream into groups according to a predetermined time unit and provides the groups of the transmission unit packets to at least one of a plurality of peer devices; and the plurality of peer devices which transmit and receive the groups of the transmission unit packets by group, wherein the streaming server groups the transmission unit packets into the groups using time information included in the data stream, and the steaming server determines whether a time interval between a currently detected time information of a current transmission unit packet and a previously detected time information of a previous transmission unit packet is longer than the predetermined time unit, if the streaming server determines that the time interval between the currently detected time information and the previously detected time information is longer than the predetermined time unit, the current transmission unit packet is grouped into a next group, and if the streaming server determines that the time interval between the currently detected time information and the previously detected time information is shorter than or equal to the predetermined time unit, the current transmission unit packet is grouped into a current group. - View Dependent Claims (17, 18, 19, 20)
