Claim:
1. A method for processing a digital broadcast signal including a 3 dimensional, 3D, content, the method comprising: encoding 3D video data for the 3D content, the 3D video data including a left picture for a left view and a right picture for a right view for a 3D image; generating signaling data having information for signaling 3D display objects for the 3D content, wherein the signaling data includes region identification information identifying a region for the 3D display objects, and sub-region disparity information indicating values of disparities applied to each of sub-regions included in the region of the 3D image for the 3D display objects when the region is divided into the sub-regions, wherein when there are two or more 3D display objects in a sub-region a value of the values of the disparities is applied simultaneously to all 3D display objects included in the sub-region, wherein the disparity is a difference between horizontal positions of a pixel representing a same point in space in the right and left view of the 3D image, wherein the region is an area for displaying the 3D display objects on a 3D display and the sub-region is a certain area included in the region, wherein the signaling data further includes sub-region location information specifying a location of each of the sub-regions in the region; and transmitting the digital broadcast signal including the encoded 3D video data and generated signaling data.
