3D-IMAGE-DATA TRANSMISSION DEVICE, 3D-IMAGE-DATA TRANSMISSION METHOD, 3D-IMAGE-DATA RECEPTION DEVICE, AND 3D-IMAGE-DATA RECEPTION METHOD

摘要

To facilitate a processing in the receiving side. A subtitle processing unit 123 converts 2D image subtitle data into stereoscopic image subtitle data conforming to a transmission format of the stereoscopic image data. In the receiving side, it is possible to easily generate display data of the left-eye subtitle overlapped with the left-eye image data of the stereoscopic image data and display data of the right-eye subtitle overlapped with the right-eye image data of stereoscopic image data based on the stereoscopic image subtitle data, and it is possible to facilitate the processing. In addition to the stereoscopic image data and stereoscopic image subtitle data, display control information including area information of the region partition set as display areas of the left-eye and right-eye subtitles and shift information is transmitted. It is possible to dynamically change disparity assigned to a part of or the entire subtitle in synchronization with the change of the image content. The shift information is generated at a sub-pixel precision level.
