Abstract: A method for transmitting a three-dimensional (3D) caption signal and caption display method are disclosed to three-dimensionally display caption text such that it fits a 3D image in a 3D display device. 3D caption box configuration information and caption text are generated to display a 3D caption within a 3D image, and the 3D caption box configuration information and the caption text are inserted into a video picture header region to code the image signal, and then, the image signal is transmitted. In the caption display method, a broadcast signal including a 3D image signal is received, and 3D caption box configuration information and caption text included in the broadcast signal are acquired. A caption image including 3D caption text disposed within a 3D caption box is then generated based on the 3D caption box configuration information and the caption text, and displayed.

Abstract: A digital broadcast receiving apparatus for providing an integrated service of a 2D image and a 3D image comprises: a demultiplexing unit configured to demultiplex a received digital broadcast signal; a PSIP or PSI/SI processor configured to extract at least any one of 3D service information related to a 2D image channel or service and 2D service information related to a 3D image channel or service from the demultiplexed digital broadcast signal; a decoder configured to decode an extension view video stream and a base view video stream from the demultiplexed digital broadcast signal; and an output formatting unit configured to format the extension view video stream and the base view video stream based on at least any one of the 3D service information and the 2D service information.

Abstract: A method of processing EPG metadata in a network according to one embodiment of the present invention includes the steps of performing a services discovery procedure utilizing multiple service discovery metadata components supplied by a service provider and processing an EPG metadata.

Abstract: A digital broadcast receiving apparatus for displaying a stereoscopic image comprises: a demultiplexing unit configured to demultiplex a received digital broadcast signal; a PSIP or PSI/SI processor configured to extract extension view video information from the demultiplexed digital broadcast signal; a decoder configured to decode an extension view video stream and a base view video stream from the demultiplexed digital broadcast signal; and an output formatting unit configured to format the extension view video stream and the base view video stream based on the extension view video information. The extension view video information may include at least any one of a relative position relationship between a camera which has generated the extension view video stream and a camera which has generated the base view video stream, the number of the extension view video streams, and information regarding an arrangement structure of the cameras.
