PROBLEM TO BE SOLVED: To make a reception-side apparatus properly receive a connection frame even in an environment where the connection frame is likely to be affected by noise.;SOLUTION: A data transmitter comprises a modulation section for modulating frames to be transmitted to a data receiver and a transmission section for transmitting the modulated frames to the data receiver. Before transmitting the data frames containing contents information to the data receiver, the data transmitter transmits a connection frame that represents transmission conditions for the data frames to the data receiver, wherein the data transmitter transmits a plurality of connection frames in which at least one out of the modulation scheme or transmission rate differs mutually as the connection frame.;COPYRIGHT: (C)2009,JPO&INPIT
