FM MULTIPLEX BROADCAST RECEIVER AND CAR NAVIGATION SYSTEM EMPLOYING IT

摘要

PROBLEM TO BE SOLVED: To receive both VICS(vehicle information and communication system) service broadcast and DGPS(differential global positioning system) service broadcast by a single receiver while time sharing without requiring high speed high accuracy time control by controlling the program receiving timing automatically. ;SOLUTION: An FM multiplex broadcast receiver employs an interval receiving system for receiving at least two asynchronous data broadcasts of different frequency while time sharing using a single receiver and comprises a frequency switching section 4 for automatically switching the program receiving time of data being broadcasted while time sharing in switching the frequency of first and second data broadcasts.;COPYRIGHT: (C)1999,JPO
