PROBLEM TO BE SOLVED: To provide a method for transmitting digital data which can transmit an image signal, a digital data signal via one transmission line, can simply apply reference matter to an existing image transmission system, and can easily obtain image and data of necessary amounts; and to provide a method for displaying the image. SOLUTION: The method for transmitting digital data includes a step of using horizontal or vertical synchronization signal of an image signal instead of a header signal of a digital data signal, and superposing the digital data signal on a vertical blanking interval except a vertical synchronizing signal, equivalent pulse and horizontal blanking interval. Further, the method also includes a step of switching a composite image signal and the digital data signal, alternately transmitting at the same transmission line, displaying the image having the composite image signal on a monitor at this composite image signal transmitting time, and displaying the image having the image data outputted from a storage unit storing the image data immediately before this digital data signal transmission on a monitor at the digital data signal transmission time.
