  • Patent number: 11005599
    Abstract: A data transmission system includes a data transmitter and a data receiver. The data transmitter outputs ‘N’-bit transmission data (where ‘N’ denotes a natural number which is equal to or greater than two). The data receiver receives the ‘N’-bit transmission data through ‘N’-number of data transmission lines. The data receiver transmits a re-transmission request signal to the data transmitter when the ‘N’-bit transmission data inputted to the data receiver are erroneous data. The data transmitter divides the ‘N’-bit transmission data in response to the re-transmission request signal and operates in a first data re-transmission mode so that the divided transmission data are resent, together with first ground data, to the data receiver.
