The present disclosure relates to a pre-5-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4-Generation (4G) communication system. Disclosed is a method of receiving a video segment from at least one streaming server by a client device using hypertext transfer protocol (HTTP) adaptive streaming in a wireless network. The method includes: acquiring media presentation description (MPD) information by receiving an MPD file from the streaming server and parsing the received MPD file; determining a first parameter to minimize a cost function considering both energy consumption required for receiving a video segment and video quality of the segment based on the MPD information; requesting at least one video segment to the at least one streaming server during a first segment request round based on the first parameter; and receiving the at least one video segment from the at least one streaming server.

Method and apparatus for HTTP adaptive streaming in wireless network environment

The present disclosure dynamically selects an optimal parameter so as to stably stream an image without user's setting in a network environment. The present disclosure determines (schedules) a path to which a general packet is to be distributed based on a path cost indicator, and determines a symbol size and the number of source symbols, which minimize or sufficiently reduce a cost function.
