发明名称 DATA COMMUNICATION SYSTEM
摘要 <p>PURPOSE:To reduce data interruption time attended with switching by sending a data with switching information prior to the switching of a transmitter, allowing a receiver side to cause synchronizing step-out based on the information, thereby starting the reconfirmation of complete coincidence of a synchronizing signal. CONSTITUTION:A synchronization generating section 12 in a receiver confirms the coincidence of all bits of the synchronizing signal at the start of reception at first to take synchronization, decides it to be the synchronizing step-out only when a dicordant signal is consecutive for a prescribed number of times to all or a part of the synchronizing signal after that and checks the synchronization to generate readout timing information. In the case of switching the transmitter, control signal information including switching information from the transmitter A is sent from the transmitter prior to the switching of the transmitter at first. A transmitter switching information detection section 16 of the receiver detects the information and controls a synchronization generating section 12 to cause the synchronizing step-out for a prescribed time based thereupon. After the prescribed time elapses, the transmitter B after the switching is in the transmission state and after the transmission from the transmitter is started, the receiver implements the reception from the start without fail.</p>
