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.

Abstract: According to a single-stage interleaved software switching converter, power factor is controlled and battery charging and current are integrally controlled on the basis of a PFC circuit of a single-stage interleaving type so that efficiency of a charging device is enhanced and the cost is reduced. Further, it is possible to remove harmful electromagnetic radiation; enhance power density and durability by using a film-type capacitor instead of the conventional electrolytic capacitor; reduce switching loss by soft switching operation and to reduce the volume of a filter unit; design magnetizing current to be small by removing a low-frequency component of a transformer and to reduce the volume; and perform high-power charging according to the number of windings of the transformer.
