[Object] To maintain perspective consistency with individual objects in an image when displaying captions (caption units) based on an ARIB method in a superimposed manner. [Solution] Pieces of caption data of individual caption units are inserted as pieces of caption sentence data (caption codes) of a caption sentence data group into a caption data stream. A data unit of extended display control (data unit parameter=0x4F) for transmitting display control information is newly defined. In a PES stream of a caption data group, disparity information is inserted into a data unit for transmitting display control information, thereby associating caption sentence data (caption sentence information) with disparity information. On the receiver side, appropriate disparity can be given to caption units that are to be superimposed on a left-eye image and a right-eye image. |
