To maintain consistency in the sense of perspective between respective objects in an image in the display of superimposition information.
A parallax information set creating unit 134 applies downsizing processing, for example, to the parallax vectors of respective pixels located in a bottom layer, obtains the parallax information of respective regions in respective hierarchies obtained by hierarchically dividing an image region, and creates a parallax information set in which the parallax vectors of the respective regions in a hierarchy selected on the basis of the space density of a parallax vector requested by a receiving side or a transmission band or the like are arranged in the hierarchical order. A multiplexer 122 multiplexes the packets of streams supplied from respective encoders so as to obtain bit stream data BSD as transmission data including the parallax information set. At the receiving side, the parallax information set is used as the same superimposition information that is superimposed upon a left-eye image and a right-eye image, whereby the superimposition information, to which parallax adjustment has been applied in accordance with a sense of perspective between respective objects in the image, can be easily used.
