Abstract
A reception side can easily recognize that metadata is inserted into an audio stream. A container of a predetermined format including an audio stream into which metadata is inserted is transmitted. Identification information indicating that the metadata is inserted into the audio stream is inserted into a layer of the container. At the reception side, it is possible to easily recognize that the metadata is inserted into the audio scream and acquire the metadata reliably without waste by performing the process of extracting the metadata inserted into the audio stream based on the recognition.
