Abstract: [object] To maintain consistency of perspective with each object in an image in the display of overlay information. [Solution] A video framing unit 112 manipulates left eye image data and right eye image data into a state according to the transmission mode, thereby obtaining stereoscopic image data for transmission. On the basis of the left eye image data and the right eye image data, at a predetermined position within an image, a view vector detecting unit 114 detects a view vector that is disparity information of one of a left eye image and a right eye image with respect to the other. A view vector encoder 115 generates an elementary stream of view vector. By a multiplexer 122, bit stream data into which the view vector stream is multiplexed in addition to a video stream, an audio stream, a graphics stream, and the like, is generated and transmitted. At the receiving side, as the same overlay information to be overlaid on the left eye image and the right eye image, overlay information to which disparity adjustment has been applied in accordance with the perspective of each object within the image can be used.
