"Stereoscopic Image Data Transmitter, Method For Transmiting Stereoscopic Image Data, And Stereoscopic Image Data Receiver"

Abstract: [Object] To maintain consistency of perspective between objects in an image in closed caption display and so forth. [Solution] A video framing unit 112 changes left eye image data and right eye image data to a state corresponding to a transmission method, and obtains transmission stereoscopic image data. A CC encoder 127 outputs closed caption data (CC data) . A Z data unit 128 outputs disparity information correlated with each of data of superimposing information such as closed caption information. This correlation is performed using Region_id. The CC data and disparity information is sent to a stream formatter 113a of a video encoder 113, so as to be embedded in a video stream as user data and transmitted. At the reception side, superimposing information subjected to disparity adjustment according to the perspective of the objects within the image can be used as the same superimposing information (closed caption information, etc.) as that superimposed on the left eye image and right eye image.
