Abstract
A data transmission and reception scheme capable of reducing required devices in the data transmission and reception system for an economical advantage, realizing the concurrent data delivery to a plurality of data reception devices, and allowing each one of a plurality of data reception devices to start the data reception at arbitrary timing. In a system for transmitting data from a data transmission device to unspecified many data reception devices that make asynchronous connections, the data transmission device carries out the repetitive transmission by repeating the operations of transmitting a prescribed amount of data to be transmitted by applying a prescribed signal conversion and then pausing the signal conversion processing for a prescribed period of time so as to provide a transmission pause state in the transmission signals which is to be utilized as a reception timing at each data repcetion device. At each data reception device, the transmission pause state in the transmission signals are detected at an arbitrary timing, and the reception of the transmission data is started by using the detected transmission pause state as the reception timing.
