Title:
MULTIPLEX BROADCAST RECEIVER
Document Type and Number:
Japanese Patent JP3716881
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To allow one multiplex broadcast receiver to keep the newest data at all times as position-correction data and traffic information data by extracting newest data of the traffic information system and correction data.
SOLUTION: A RAM 33 stores data, denoting a frequency at which DGPS correction data are broadcast and data denoting a frequency at which VICS data are broadcast. Data of frequencies of broadcast stations broadcasting DGPS correction data are read from the RAM 33, and the frequency data are fed to a reception circuit 22 through a port 34 to select broadcast stations broadcasting the DGPS correction data. Similarly the frequency data of the broadcast stations, broadcasting VICS data, are read from the RAM 33 and the broadcast stations are selected. Thus, even when the DGPS correction data and the VICS data are broadcast from different broadcast stations, both the data are received by one receiver 20.
