Abstract: A transmission method in transfer of content using an IP (Internet Protocol) packet performed through broadcast 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 the IP packet, and a transmission step of transmitting the generated frame. In the generation step, 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 within a second transfer unit positioned at a head within the frame, and the object IP packet does not undergo header compression.

Abstract: A transmission method in transfer of content using an IP (Internet Protocol) packet performed through broadcast includes a generation step (S151) 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 the IP packet, and a transmission step (S152) of transmitting the generated frame. In the generation step (S151), reference clock information that indicates time for reproduction of the content on a reception side is contained in the first transfer unit positioned at a head within the frame. This provides a transmission method capable of reducing processes for acquiring the reference clock information on a reception side.

Abstract: According to one aspect of the present disclosure, a transmission method for enabling transmission of content using a broadcast wave and a communication channel includes: transmitting auxiliary information using at least the broadcast wave, the auxiliary information being information for synchronizing content transmission using the broadcast wave and content transmission using the communication channel when the content is transmitted using the broadcast wave and the communication channel, and the auxiliary information causing a reception side to perform the synchronization when the reception side receives the auxiliary information. Therefore, even if timing of starting reception of the content through the communication is delayed, the reception side can play back the content by a combination of the broadcasting and the communication.
