In order to allow bit-interleaved-parity calculation to be easily performed while maintaining compatibility with an existing system during transmission of data having mixed bit rates, header information of a first bit rate is added to data of the first bit rate and data of a second bit rate, time-division multiplexing is performed on the header-information-added data signals to generate a data string and a frame header is added thereto to generate a frame signal, parities of the frame signal that is sequentially generated are determined, parity bits for parity checking for the data signals of the first bit rate and the data signals of the second bit rate are inserted into the frame signal, based on a result of the parity calculation.
