Abstract

Abstract In an RDS receiver being capable of receiving an RDS broadcast wave on which RDS data, such as a plurality of alternative frequency data and programme identification data of the same network group, are frequency-multiplexed, a method for selecting a broadcasting station is used when the receiving condition has deteriorated in the midst of receiving a radio broadcast wave: the RDS receiver automatically starts to tune to an alternative broadcasting station within the same broadcasting network group in order to receive the same programme, preferably a broadcasting station located comparativily close to the receiver is selected. Since, in accordance with this invention, the tuning is performed by reading back the alternative frequency data from the latest in the stored list of alternative frequencies, thus selecting a new network station within a short period of time.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 208 words
A method of selecting a broadcasting station for an RDS receiver being capable of receiving an RDS broadcast wave of the type, wherein a plurality of alternative frequency data and programme identification data concerning about the same broadcasting network group are frequency-multiplexed on a broadcast wave, comprising the steps of: a first processing step for storing said plurality of alternative frequency data in a prescribed area of a memory, in the order decoded, to provide a list of alternative frequencies for each network; a second processing step for storing said programme identification data, upon receiving a command, by decoding a received broadcast wave from a listening broadcasting station; and a third processing step for selecting an alternative broadcasting station, by reading back the alternative frequency data, in the order from newly stored, of the same broadcasting network group as that of the listening broadcasting station from the list of alternative frequencies provided by the first processing step, upon detecting a presence of such alternative broadcasting station, which corresponds to the read-out alternative frequency data, when whose programme identification data is discriminated identical to the programme identification code stored at the second processing step and whose broadcast wave has a signal level at or above a predetermined signal level.
Claim 2
Dependent Claim 33 words
A method of selecting a broadcasting station for an RDS receiver as defined in claim 1, wherein a network follow-up process is initiated automatically when a receiving condition is changed to the worse.
Claim 3
Dependent Claim 33 words
A method of selecting a broadcasting station for an RDS receiver as defined in claim 1, wherein a network follow-up process is initiated based on a tune-in command given through an operation unit.
Claim 4
Dependent Claim 54 words
A method of selecting a broadcasting station for an RDS receiver as defined in claim 1, wherein an alternative broadcasting station is selected by controlling a division ratio of a programmable divider, which constitutes a part of a front end, based on the alternative frequency data read out from the list of alternative frequencies.
