A response time until initial presentation decreases in such cases as reception of a service and reproduction of reception data after accumulation of the reception data. Identification information based on which a packet handled with priority is identifiable is inserted into each of transmission packets at the time of transmission of a transmission stream containing the transmission packets disposed successively in the transmission stream. For example, each of the transmission packets is a multilayered packet containing a multiplexed transport packet in the uppermost layer. For example, the identification information is inserted into packets in a part or all of layers of each of the multilayered packets. |
