It is possible to enable a reception side to easily recognize that metadata is inserted into an audio stream. A metafile including meta information for acquiring an audio stream into which metadata is inserted through a reception device is transmitted. The identification information indicating that the metadata is inserted into the audio stream is inserted into the metafile. At the reception side, it is possible to easily recognize that the metadata is inserted into the audio stream based on the identification information inserted into the metafile.
