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.
