1. A method of combining three dimensional (3D) image and auxiliary data in a display area of a stereoscopic screen, the method comprising acts of: obtaining information describing scaling and/or shifting for use with the 3D image; resizing the 3D image in accordance with the information by scaling and/or shifting in at least one of a horizontal direction and a vertical direction of a display area to create a spatial area fitting in a portion of the display area that is not occupied by the 3D image to be occupied by the auxiliary data; combining the scaled and/or shifted 3D image and the auxiliary data such that the auxiliary data is placed within the spatial area; creating a left border region and a right border region that extend into the portion of the display area that is occupied by the 3D image; and adjusting a depth position of the left and right border regions such that each border region is closer to a viewer than any of the portion of the 3D image in the display area that is overlapped by the left and right border regions.
