The present disclosure relates to a communication technique for converging IoT technology with a 5G communication system for supporting a higher data transmission rate than a 4G system, and a system therefor. The present disclosure may be applied to intelligent services based on 5G communication technology and IoT-related technology (e.g. smart homes, smart buildings, smart cities, etc.). A method for receiving image data for a virtual-reality streaming service by an electronic device according to an embodiment of the present invention comprises: a step in which the electronic device determines whether to execute an adaptive virtual-reality streaming service on the basis of a bandwidth state; and a step in which, if it is determined to execute the adaptive virtual-reality streaming service, the electronic device requests and receives, from a server, the image data for the adaptive virtual-reality streaming service on the basis of head-tracking information and bandwidth information collected in advance.
