1. A transmission method, comprising:
generating frames, each frame including first control data, second control data, and a first transfer unit, the first transfer unit includes one or more second transfer units, the first control data including first information indicating a start position of the one or more second transfer units within the first transfer unit, the second control data including second information indicating whether the first control data includes reference clock information or not, the first control data including the reference clock information when the second information indicates the first control data includes the reference clock information; and
transmitting the frames, wherein
the reference clock information is cyclically transmitted,
(i) a first frame among the frames includes the first control data including the reference clock information and the second control data indicating that the first control information includes the reference clock information, and (ii) a second frame among the frames includes the first control data not including the reference clock information and the second control data indicating that the first control data does not include the reference clock information, and
the reference clock information is based on Precision Time Protocol (PTP) prescribed by Institute of Electrical and Electronics Engineers (IEEE) 1588.
