[Object] To maintain perspective consistency among individual objects in an image in superimposition display of a caption (caption unit) in an ARIB method.;[Solution] A multiplexed data stream including a video data stream and a caption data stream is transmitted from a broadcast station to a set top box. A video data stream supplied from a video encoder 113 includes stereo image data. A caption data stream supplied from a caption encoder 133 includes data of captions (caption units) in the ARIB method serving as superimposition information and disparity information (disparity information set). In the caption data stream, the pieces of data of a certain number of captions that are to be displayed on the same screen are sequentially arranged via a separator. Also, the disparity information (disparity information set) inserted into the caption data stream includes a certain number of pieces of disparity information added with respective pieces of identification information indicating the arrangement order of the pieces of data of the certain number of captions.
