<p>Disparity information is transmitted such that reception processing of a legacy 2D-compatible receiving apparatus is not interrupted. A multiplexed data stream includes a first private data stream (2D stream) including superimposition information data and a second private data stream (3D extension stream) including disparity information. A first descriptor and a second descriptor including respective pieces of language information corresponding to the first private data stream and the second private data stream are inserted into the multiplexed data stream. The language information included in the second descriptor represents a non-language. Based on the language information, the legacy 2D-compatible receiving apparatus can extract only the 2D stream from the multiplexed data stream and decode the 2D stream easily with a high accuracy. That is, since the 3D extension stream is not decoded, the reception processing can be prevented from being interrupted by the decoding.</p> |
