A digital broadcast receiving apparatus for displaying a stereoscopic image includes 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.

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.

3D caption signal transmission method and 3D caption display method

Digital broadcast receiving method comprising receiving base and additional view video streams and stereoscopic characteristics information. The method comprising identifying a virtual channel carrying a 3D broadcast service delivering additional and base view video streams encoded using different codecs using a service type field, wherein the service type field is included in a TVCT of a PSIP in an ATSC-type digital broadcast and identifying a codec type of each of the base and the additional view video streams using a stream type field included in a PMT, wherein the stream type field is related to each of the base and the additional view video streams, and wherein a value of the stream type field indicates the codec type of each of the base and the additional view video streams. The method also comprising processing base and additional view video streams for supporting the 3D broadcast service using the TVCT.

Digital broadcast receiving method providing two-dimensional image and 3D image integration service, and digital broadcast receiving device using the same

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. The relative position relationship may include at least any one of the direction in which the camera, which has generated the extension view video stream, is positioned and the degree of separation in the direction based on the camera which has generated the base view video stream. Accordingly, a signal for a stereoscopic image in a digital broadcast can be checked and processed, so a stereoscopic image can be displayed.
