Abstract: A method, apparatus, and system for providing a zoomable stereo 360 virtual reality (VR) video are provided. The method includes receiving media presentation description (MPD) information including information on video bit streams obtained by encoding each piece of video data by different conditions, decoding a video bit stream corresponding to a communication environment of a client device based on the MPD information and outputting a streaming video, receiving a user's resizing input for the streaming video, and decoding a video bit stream corresponding to the resizing input and outputting an adjusted streaming video.
