A user device and a server provide a VR experience service to a user without significant interruption in response to a user's movement. In particular, the server may create a stitched image of a 360-degree video of a predetermined virtual environment according to a user movement state and transmit the stitched image to a user device. The user device may i) receive, from a server through a wireless link, a stitched image of a 360-degree video of a predetermined virtual environment which is dynamically changed according to a user movement state and ii) render a stereoscopic image at a user's view-point which is dynamically changed according to a user's head movement, using the received stitched image of the 360-degree view of the predetermined virtual environment.

Providing virtual reality experience service

Provided are providing a virtual reality (VR) contents streaming service. For providing the VR contents, a server may be configured to receive a request message for requesting a predetermined VR contents from a user device through a communication network, determine a field of view (FOV) area in each image frame of the predetermined VR contents and a plurality of extended areas adjacent to the FOV area, receive a viewing area switching request from the user device, wherein the viewing area switching request includes information on a viewing area switching direction and a viewing area switching speed, calculate a size of each extended area based on at least one of the viewing area switching direction, the viewing area switching speed, and a location of an object to be displayed in each extended area, redecide a FOV area and a plurality of extended areas based on the calculated size of each extended area, and encode image data of the redecided FOV area and image data of the plurality of redecided extended areas and transmitting the encoded image data to the user device.

Providing streaming of virtual reality contents

The disclosure is related to a personalized user interface having at least one moving image produced based on a multimedia stream received in real time from a preferred streaming server. A service server for providing the personalized user interface may perform receiving multimedia streams transmitted in real time from preferred streaming servers selected based on user interface configuration information, obtaining personalized items based on the user interface configuration information, producing a single multimedia stream for the personalized user interface by combining the received multimedia streams and the obtained personalized items, and transmitting the produced single multimedia stream to the user device.

Personalized user interface for managing multimedia streams

An apparatus and method for providing a game service in cloud computing environment. A method may be provided for providing a streaming game service using a plurality of cloud computing servers. The method may include receiving user inputs from at least one user equipments, executing and progressing at least one game program in response to the user inputs, capturing audio and video data as progress results of the executed at least one game program, and streaming the captured audio and video data to a respective user equipment.
