<p>[Object] To maintain perspective consistency among individual objects in an image in display of superimposition information. [Solution] A disparity information set creating unit 134 performs a downsizing process, on disparity vectors of respective pixels positioned in the bottom layer, obtains pieces of disparity information of respective areas in individual layers obtained by hierarchically dividing an image area, and creates a disparity information set in which disparity vectors of respective areas in a layer selected on the basis of the spatial density of disparity vectors requested by a receiver side or a transmission band are arranged in hierarchical order, for example. A multiplexer 122 multiplexes packets of streams supplied from the respective encoders, and obtains bit stream data BSD serving as transmission data including the disparity information set. On the receiver side, superimposition information in which disparity adjustment has been performed in accordance with the perspective among individual objects in an image can be easily used as the same superimposition information that is to be superimposed on a left-eye image and a right-eye image, by using the disparity information set.</p> |
