Abstract
Disclosed is an information transmitting and receiving apparatus comprising a transmitting means for sequentially transmitting a plurality of information signals each including a synchronizing signal, an address signal and a data. The information transmitting and receiving apparatus further comprises a receiving means which sequentially receives the transmitted information signals and compares a current data signal of a certain address with the previously received data signal of the same address, and, if both the data signals do not coincide with each other, demands the transmitting means to transmit again the current data signal in sequence irrespective of the order of storing the aforesaid information signals thereby achieving the transmission of the data to be again transmitted.
