Abstract: A method for servicing a 2 dimension image and a 2 dimension-3 dimension mixed image by inserting a 3 dimension image into a specific field of the 2 dimension image is provided to reproduce a 3 dimension image in only some scenes of a specific event in a 2 dimension moving picture of a digital broadcast, thereby reducing fatigues of eyes. A 2 dimension image is converted to a 3 dimension image on a specific field. Information about a position and size of the specific field is stored. A mask is applied to a left image of the 3 dimension image to be displayed on the specific field of the 2 dimension image. The left image is attached to a reference point position of the specific field. The 2 dimension attached to the 3 dimension image is transmitted or stored through a multiplexing method. The transmitted or stored 2 dimension image is copied and expanded by two times in a cross direction.
