A data transmission method which maintains the direct current (DC) balancing of each channel and compensates for the skew between channels when digital video data made up of graphic data, control data and clock data is transmitted in series via channels allocated to the data, and a data receiving method, a data transmitter and a data receiver, are provided. In this method, the disparity representing the degree of the direct current (DC) balancing of the graphic data is calculated whenever the graphic data is transmitted. The calculated disparities are accumulated whenever the graphic data is transmitted. Scrambling is performed in which, when the accumulated disparity does not amount to the predetermined critical value, the received graphic data is transmitted without change, and when the accumulated disparity amounts to the predetermined critical value, the received graphic data is inverted.
