Abstract: The present invention relates to providing a method and/or an apparatus for transmitting/receiving a broadcast signal for a 3-dimensional (3D) broadcast service. The method for transmitting a broadcast signal according to one embodiment of the present invention comprises the steps of: downsampling each of a left picture frame, a right picture frame, a depth picture frame for the left picture frame and a depth picture frame for the right picture frame, and encoding a packed frame which packs at least one frame of the downsampled frames into one frame, generating a broadcast signal comprising signaling information for the encoded packed frame and a picture related to the packed frame; and sending the generated broadcast signal.

Abstract: A method for processing a 3-dimensional image including an additional object in a system providing a multi-view image according to one embodiment of the present invention comprises the steps of: receiving video images and depth images from a plurality of views; configuring one additional object of additional objects displayed in the video images from the plurality of views as a reference additional object; calculating disparity between pixels of an area in which the reference additional object is displayed and a video image, which is adjacent to an edge of the reference additional object; applying a disparity value, which is larger the or equal to a value of the calculated disparity, to the reference additional object, so as to combine the reference additional object with a first view video image and a second view video image; and formatting the first view video image and the second view video image, with which the reference additional object has been combined, as 3-dimensional images.
