Abstract
Disclosed is a technology for providing a content on the basis of DASH adaptive to a variable bandwidth. The present invention may comprise: a bandwidth measurement unit for measuring a bandwidth of a network connected to a terminal at predetermined time intervals; a segment generation unit for generating a plurality of segments, wherein the plurality of segments have a predetermined bitrate difference therebetween; and a media information generation unit for generating a media presentation description which includes information on the representation including the plurality of generated segments, wherein the segment generation unit calculates segment lengths using arithmetic operations on the predetermined time interval and the probability that an ith bandwidth itself among bandwidths of the network measured at the predetermined time intervals is increased or decreased by half of the predetermined bitrate difference, and generates a plurality of segments corresponding to the calculated lengths.
