Abstract: A system and method for delivering moving route prediction-based content is provided, in terms of a server, as a user terminal allows producing an image at the future time point, at the user's final position, which is predicted, based on a total delay time of a network, rather than producing images at every time point, it is possible to reduce the data amount required for creating the content, and as the image produced at the user's final position according to the user moving route is stored in the buffer, it is possible to provide smooth content service without delay. In addition, the user may experience virtual reality as a 360° image suitable for the user's moving position from the user's point of view is played through a HMD of the user terminal S1, and the user may also use a lively content by making the 360° image stereoscopic.

Abstract: Provided is a method for creating a virtual reality content, storing the virtual reality content in a transmission buffer, and after that, managing the transmission buffer. A server creates the virtual reality content based on user's motion information, stores the virtual reality content in the transmission buffer and is allowed to modify the virtual reality content stored in the transmission buffer based on subsequently received user's motion information, so that the most recent user's motion information can be appropriately reflected in the virtual reality content. It is possible to provide a more immersive virtual reality service.
