TRANSMISSION METHOD, RECEIVING METHOD, TRANSMISSION DEVICE AND RECEIVING DEVICE

摘要

A transmission method includes a generation step of generating a transfer frame that stores a plurality of second transfer units that each store one or more first transfer units that each store an IP (Internet Protocol) packet, and a transmission step of transmitting the generated frame. In the generation step, first reference clock information that indicates time for reproduction of the content in data structure different from data structure of an MMT (MPEG Media Transport) packet is contained in an object IP packet stored in a first transfer unit positioned at a head in a second transfer unit positioned at a head within the frame, second reference clock information that indicates time for reproduction of the content is stored in control information within the frame, and the object IP packet does not undergo header compression.
