    摘要： 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 syncronization 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.

    摘要： A transmitting method for transmitting encoded data obtained by hierarchically encoding a video image includes: generating an encoded stream that includes time information and the encoded data, the time information indicating a time at which decoding or displaying processing of the encoded data is performed, and transmitting the generated encoded stream, wherein the encoded data includes a plurality of sets each including a plurality of access units and the time information includes first time information which indicates a time at which the processing performed on a first access unit of the first set is performed and which is based on a reference clock, and second time information used to specify a time at which the processing performed on a second access unit of the second set is performed and which is based on the reference clock.

    摘要： A data transmission method according to one aspect of the present disclosure includes: generating a plurality of MPUs, reference clock time information, and leading clock time information indicating a leading PTS that is a clock time at which a leading access unit in the MPU is presented, transmitting the generated plurality of MPUs, reference clock time information, and leading clock time information, wherein the leading clock time information indicates the leading PTS of the plurality of MPUs of which presentation is started after the leading clock time information is transmitted in the generated plurality of MPUs, and each of the generated plurality of MPUs indicates a time point at which each access unit that does not exist in a head of the MPU is presented as a relative value to a time point of another access unit in the MPU.
