Abstract
Data counters and perform a counting operation which is synchronized with the respective timing of receiving multiplex data from a VICS data broadcasting station and a D-GPS data broadcasting station. While receiving the multiplex data from the VICS data broadcasting station, based on an output C of the data counter and a BIC detection output BP, block synchronization is detected. When the broadcasting station is switched from the VICS data broadcasting station to the D-GPS data broadcasting station, an output C of the data counter is selected in response to a control signal CONT and block synchronization is detected based on an output C and an output BP. Further, an output C is always inputted to the block counter. Thus, even while receiving the multiplex data from the D-GPS data broadcasting station, frame synchronization of the multiplex data of the VICS data broadcasting station is detected without causing miscounting.
