Abstract:
A data transmission and reception method for carrying out data transmission and reception between a data transmission device and unspecified many data reception devices that make asynchronous connections, comprising:a first step for applying a prescribed signal conversion to a prescribed amount of transmission data to obtain transmission signals, and transmitting the transmission signals, at the data transmission device;a second step for pausing the signal conversion for a prescribed period of time after the first step so as to provide a transmission pause state in the transmission signals which is to be utilized as a reception timing at each data reception device, at the data transmission device;a third step for carrying out a repetitive transmission by repeating the first step and the second step, at the data transmission device;a fourth step for detecting the transmission pause state provided in the transmission signals, at each data reception device; anda fifth step for receiving the transmission data by starting a data conversion of received transmission signals, by using the transmission pause state detected by the fourth step as a reception timing, at each data reception device;wherein the first step transmits the transmission data formed by information contents, by specifying a display time by which each information content is to be displayed at each data reception device, and the fifth step acquires the display time specified for each information content contained in received transmission data and displays each information content when the display time comes while starting a reception of a next information content.
