Abstract:
A data transmission method comprising:a receiving step of receiving eight-bit word string data indicating signal information; an insertion step of inserting an additional word data group including specific synchronous word data and at least one item of auxiliary word data, each data having eight bits and a predetermined code, between words of the eight-bit word string data in accordance with a predetermined timing signal; a conversion step of converting the eight-bit word string data provided with the additional word data group into ten-bit word string data; a forming step of forming composite ten-bit word string data including the additional word data group containing ten-bit synchronous word data which is converted from the specific synchronous word data; and a transmission step of transmitting the composite ten-bit word string data, wherein in said insertion step, the additional word data group is selected so that a running disparity of the ten-bit synchronous word data contained in the additional word data group of the composite ten-bit synchronous word data is consistently one of positive and negative.
