METHOD AND APPARATUS OF PROVIDING DATA STREAMING SERVICE

摘要

PURPOSE: A data streaming service providing method and apparatus thereof are provided to adaptively control the size of a file piece in a streaming service method based on a P2P(Peer to Peer) according to network states, kinds of services, and terminal states. CONSTITUTION: A buffer map calculation unit(107) creates a buffer map based on information for file pieces and the bunch of file pieces included in each peer. The buffer map calculation unit deducts necessary file piece numbers by comparing buffer map information of each peer received through a communication unit. A data transmission unit(111) transmits the bunch of the file pieces or the file piece data by referring to the deducted file piece number through the buffer map calculation unit. A transmission speed confirmation unit(113) confirms a transmission speed.
