Claim:
1. A method for displaying a three-dimensional (3D) image in an image display device, the method comprising: receiving, via a receiving unit, a broadcast signal including a broadcast image and signaling information; parsing the signaling information from the broadcast signal, wherein the signaling information includes intrinsic camera parameters and extrinsic camera parameters, and wherein the intrinsic camera parameters specify optical characteristics of at least one of a real camera and a virtual camera, and the extrinsic camera parameters indicate a geometrical position and direction of the at least one of the real camera and the virtual camera; wherein the extrinsic camera parameters include a first field indicating whether a parameter included in the extrinsic camera parameters is related to the real camera or the virtual camera; generating a virtual view image using the intrinsic camera parameters and the extrinsic camera parameters at a virtual camera position; and formatting, via a formatter, the virtual view image and the broadcast image for displaying the 3D image in the image display device, wherein the extrinsic camera parameters further include a third field specifying an identifier of the real camera or the virtual camera, and wherein the extrinsic camera parameters further include a fourth field specifying intrinsic camera parameters which are applied to a camera having the identifier specified by the third field included in the extrinsic camera parameters.
