Abstract
An apparatus for adaptive streaming in multiple narrowband wireless communication environment comprises a communication unit configured to perform multi-communication with a server using a TCP and an UDP, a network monitor unit configured to collect state information on each of a plurality of narrowband networks, and a parameter control unit configured to: based on the collected state information on each of the plurality of narrowband networks, select a quality of video segment to be requested and one of the TCP protocol and the UDP protocol to be used in each of the plurality of narrowband networks, or determine a data size of redundant data for data loss restoration for each of the plurality of narrowband networks.
