Abstract

Abstract An FM receiver for use in a Radio Data System (RDS), wherein a PTY (Program Type) code, M/S (Music/Speech Switch) code and DI (Decoder Identification) code are extracted from received RDS data, stored sound reproducing characteristic data, such as of tone quality, acoustic field and sound volume that correspond to the extracted codes are read from a data memory, and predetermined sound reproducing characteristic is then set automatically in accordance with the read-out sound reproducing characteristic data to provide the RDS receiver with the optimal condition in tone quality, acoustic field and sound volume for reproducing a high quality FM sound in view of the contents of a program and/or a mode of broadcasting.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 99 words
An RDS receiver comprising: memory means for storing predetermined sound reproducing characteristic data corresponding to a PTY (Program Type) code, M/S (Music/Speech Switch) code, and DI (Decoder Identification) code contained in RDS data; extractor means for extracting the PTY code, M/S code and DI code from the received and decoded RDS data; reader means for reading the sound reproducing characteristic data that correspond to the extracted PTY code, M/S code and DI code from said memory means; and control means for controlling sound reproducing characteristics of a reproducing FM sound in accordance with the read-out sound reproducing characteristic data.
Claim 2
Dependent Claim 27 words
An RDS receiver as defined in claim 1, further including display means coupled to said control means for displaying information relating to the sound reproducing characteristic data.
Claim 3
Dependent Claim 46 words
An RDS receiver as defined in claim 1, wherein said control means controls sound volume control circuits, tone quality control circuits and an acoustic field control circuit for controlling sound reproducing characteristics of a reproducing FM sound in accordance with the read-out sound reproducing characteristic data.
Claim 4
Dependent Claim 23 words
An RDS receiver as defined in claim 3, wherein said sound volume control circuits consist of a pair of electronic sound volume controllers.
Claim 5
Dependent Claim 21 words
An RDS receiver as defined in claim 3, wherein said tone quality control circuits consist of a pair of graphic equalizers.
Claim 6
Dependent Claim 27 words
An RDS receiver as defined in claim 3, wherein said acoustic field control circuit consists of a surround circuit which can select a plurality of surround modes.
