Abstract:
A data transmission method, comprising the steps of:obtaining 8-bit word string data showing signal information, assigning two 8-bit word synchronous data having preset codes between words of said 8-bit word string data corresponding to a predetermined timing signal and after bit converting said two 8-bit word synchronous data to 10-bit word string data, a composite 10-bit word string data having a part in which two consecutive 10-bit word synchronous data are inserted is obtained and said composite 10-bit word string data is put out for transmission; andwhen bit converting said 8-bit word synchronous data, if the immediately preceding word data is word data having a plus running disparity, said 8-bit word synchronous data is converted to 10-bit word synchronous data having a minus running disparity, and if the immediately preceding word data is word data having a minus running disparity, said 8-bit word synchronous data is converted to 10-bit word synchronous data having a plus nruning disparity.
