DIGITAL BROADCAST SIGNAL PROCESSING METHOD AND DEVICE

摘要

The present invention relates to a device and a method for processing digital broadcast signals comprising three-dimensional images. According to an embodiment of the present invention, the digital broadcast signal processing method comprises the steps of: encoding a video stream of a two dimensional reference image; encoding a video stream of an additional image for generating a binocular-disparity three-dimensional image together with the encoded two dimensional reference image; generating signaling information such that the video stream of the encoded additional image is processed only in a three-dimensional image signal receiver; generating a first broadcast signal comprising the video stream of the encoded reference image; generating a second broadcast signal comprising the video stream of the encoded additional image and the signaling information; and transmitting the first broadcast signal and the second broadcast signal to different channels respectively.
