Abstract: A data processing apparatus includes a scrambling processing unit and a sending unit. The scrambling processing unit is configured to generate a Pseudo-Random Binary Sequence (PRBS), perform a modulo-2 addition on the pseudo-random sequence and data frame data to scramble the data frame data including first load data, use one section of a part of the pseudo-random sequence on which the modulo-2 addition is performed with the data frame data as an identification sequence, and carry status information corresponding to the identification sequence in frame header information. The sending unit is configured to send the frame header information carrying the status information and the scrambled first load data. Through the scrambling process, continuous run-lengths of “1” and “0” in the data frame data are quite short, while basically the same probability of occurrence is maintained, which is favorable to transmission of the data frame data, thereby alleviating error code problems.
