Disclosed are a server, a peer terminal, a data play management method and a recording medium of a personal video recorder (PVR) system supporting P2P streaming. The server according to an embodiment of the present invention comprises: a buffering allocation part for allocating the buffering of data in a first play section, which is before live streaming time, to an unused storage space of a first peer viewing live streaming among peers of the PVR system. The server may further comprise: a caching section determining part for determining a first play section to be cached by the first peer among play sections before live streaming time based on data replication degrees among the peers for each play section and the viewing time distribution of the peers. According to the embodiment, buffering efficiency can be improved via cooperative buffering for caching play sections before live streaming time by utilizing the unused storage space of a peer viewing live streaming in the P2P PVR system. Also, average play continuity can be improved greatly by controlling buffering efficiently in consideration of data replication degrees for each section before live streaming time and the viewing time distribution of users simultaneously. |
