Abstract: The present invention provides a data transmission method including: sending, by a transmitter, a source data frame to a receiver, and saving the source data frame; sending, by the transmitter, other data frames to the receiver, and saving the other data frames; receiving, by the transmitter, a data retransmission notification which is related to the source data frame and sent by the receiver; and retrieving, by the transmitter, the source data frame and other data frames from a storage space, where the other data frames are sent by the transmitter to the receiver in a time period from sending the source data frame by the transmitter to receiving the data retransmission notification by the transmitter, and retransmitting the source data frame and the other data frames to the receiver.

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.

Abstract: A method, system and device for eliminating intra-pair skew are disclosed. The method includes: measuring a phase difference between the received differential signals as a transmission delay difference; and compensating delays of the differential signals using the transmission delay difference, to eliminate intra-pair skew of the differential signals. A phase difference measuring apparatus is used to measure a phase difference between the differential signals as the transmission delay difference, so that the transmission delay difference may be adjusted according to the phase difference. Therefore, the procedure for eliminating intra-pair skew is effectively simplified, and the effect of adjusting the transmission delay difference is improved.
