摘要： A transmitting method includes: inputting, per unit time, a plurality of transfer packets less than or equal to a predetermined number; and transmitting, per the unit time, the plurality of transfer packets that have been input, in a state where definitions compliant with a receiving buffer model are satisfied (S2301). Each of the plurality of transfer packets includes a variable-length packet header and a variable-length payload. The definitions compliant with the receiving buffer model are predetermined for guaranteeing a buffering operation of a receiving device, and specify converting a first packet into a second packet and outputting the second packet from a buffer of the receiving device at a predetermined extraction rate. The first packet is included in the transfer packets received and includes a variable-length packet header and a variable-length payload. The second packet has a fixed-length packet header that is extended.
