[Object] To provide suitable disparity using a disparity information set adapted to the type of superposition information.;[Solution] A disparity information set creating unit 131 creates predetermined sets of disparity information sets. Examples of the disparity information sets include general-purpose disparity information sets, and disparity information sets for particular service application. Each set of the disparity information sets that is created at the disparity information set creating unit 131 and transmitted along with stereoscopic image data is added with identification information indicating the type of superposition information regarding which disparity information included in this disparity information set should be used. The predetermined sets of disparity information sets are transmitted to the reception side, for example, by being inserted in a user data region of a video data stream. With the reception side, suitable disparity may be provided to the same superposition information (closed caption information, subtitle information, graphics information, text information, etc.) to be superimposed on a left eye image and a right eye image using the disparity information set adapted to the type of this superposition information based on the identification information.

1. A stereoscopic image data transmission device comprising:
a disparity information creating unit configured to create predetermined sets of disparity information sets; and a data transmission unit configured to transmit said predetermined sets of disparity information sets created at said disparity information creating unit along with stereoscopic image data including left eye image data and right eye image data; wherein each set of said disparity information sets includes disparity information belonging to a predetermined number of screen regions of an image for providing disparity to superposition information to be superimposed on the image made up of said left eye image data and said right eye image data; and wherein each set of said disparity information sets is added with identification information indicating a type of said superposition information regarding which disparity information included in this disparity information set should be used, in which the disparity information indicates to shift the superposition position in a direction among a plurality of directions and by an amount among a plurality of amounts.
