Title: VIDEO STREAMING APPARATUS AND METHOD IN ELECTRONIC DEVICE
Abstract:
Disclosed is a 5G or pre-5G communication system for supporting a data transmission rate higher than that of a 4G communication system such as LTE. To this end, an electronic device transmits a request message to a server through each of a plurality of communication paths at least based on a multi-radio access technology, and receives a video segment from the server through each of the plurality of communication paths according to the request message. The electronic device estimates a transmission quality at each communication path on the basis of video segments received for each of the plurality of communication paths at an arbitrary wireless search point satisfying at least one preset condition. The electronic device can determine, by the transmission quality estimated according to each of the plurality of communication paths and the preset reference transmission quality, one communication mode, among a plurality of communication modes, for designating at least one communication path for supporting the video streaming, among the plurality of communication paths.
