Abstract: A specific UTC time corresponding to a specific NPT time is appropriately obtained in a reception side without being influenced by occurrence of a leap second.Transmission media of a program are transmitted, and mapping information between an NTP time represented by a relative time from a beginning of a program and a UTC time represented by an absolute time is intermittently transmitted. Leap second adjustment information is included in the mapping information. In the reception side, the specific UTC time corresponding to the specific NPT time obtained on the basis of the mapping information can be adjusted on the basis of the leap second adjustment information, and the influence of occurrence of the leap second can be avoided.

Abstract: A transmission stream is generated. In the transmission stream, a first transmission packet where transmission media is included in a payload and a second transmission packet where information relating to the transmission media is included in the payload are time division multiplexed. The transmission stream is transmitted to a receiving side through a predetermined transmission path. If the transmission media included in the payload of the first transmission packet is file data configuring the predetermined contents, information relating to the predetermined contents is inserted into a header thereof. At the receiving side, the first transmission packet including the file data configuring the predetermined contents can be acquired easily and accurately based on the information.
