<p>Depth control of graphics to be overlaid and displayed on a three-dimensional image in a receiving side can be sufficiently performed. Disparity information obtained for each of pictures of image data is inserted into a video stream, and then, the video steam is transmitted. Depth control of graphics to be overlaid and displayed on a three-dimensional image in a receiving side can be sufficiently performed with the picture (frame) precision. Identification information for identifying whether or not there is an insertion of disparity information into a video stream is inserted into a layer of a container. Due to this identification information, a receiving side is able to easily identify whether or not there is an insertion of disparity information into a video stream and to appropriately perform depth control of graphics.</p> |
