A1

[Problem] To provide a reception device in which MMTP packets can be recovered in an appropriate order even when a leap second is inserted. [Solution] A recovery unit 36 recovers data from a MMTP packet transmitted by a transmission device. At a time of a leap second which is inserted in order to keep Coordinated Universal Time close to universal time, a time monitoring unit 51 inputs, to the recovery unit 36, insertion ongoing information indicating that the time is at the leap second. A count unit 35 inputs, to the recovery unit 36, time information indicating the current time on the basis of Coordinated Universal Time. In addition, in a case where the MMTP packet was generated at a timing corresponding to the leap second, the MMTP packet includes leap second information indicating that the MMTP packet was generated at the leap second. If the MMTP packet includes the leap second information indicating that the MMTP packet was generated at the leap second, the recovery unit 36 recovers the MMTP packet at a timing based on the time information that was inputted from the count unit 35 when the insertion ongoing information was inputted.
