<p>[Solution] A subtitle processing unit 123 converts two-dimensional image subtitle data into stereoscopic image subtitle data conforming to the transmission format of stereoscopic image data. The reception side can readily generate, based on the stereoscopic image subtitle data, the display data of a left eye subtitle to be superimposed on left eye image data that stereoscopic image data has, and the display data of a right eye subtitle to be superimposed on right eye image data that the stereoscopic image data has, which realizes facilitation of processing. Display control information including the area information of sub regions set as the display areas of left eye and right eye subtitles, target frame information, and disparity information is transmitted in addition to the stereoscopic image data, and stereoscopic image subtitle data. Disparity to be provided to left eye and right eye subtitles can dynamically be changed in sync with change in the contents of an image. Shift information is generated with sub pixel precision.</p> |
