The digital broadcast signal processing apparatus and method

The present application relates to an apparatus and method for a digital broadcast signal comprises a three-dimensional image processing. According to one embodiment of the present invention, the digital broadcast signal processing method comprising the steps of: a two-dimensional reference image for video stream encoding; generates a video image of the binocular parallax of additional three-dimensional image with two-dimensional reference image for encoding the encoded stream; generating signaling information, such that the encoded video stream only additional image processing three-dimensional image signal receiver; broadcast signal to generate a first video stream comprises encoded reference image; generating the additional image comprises a video encoding second broadcast signal stream and signaling information; transmitting through different channels respectively, and the first broadcast signal and the second broadcast signal.
