(54) | A RDS receiver |
(57) The present invention provides an RDS receiver for use with an automobile which receives
data concerning radio broadcasting stations incorporated within a network and is capable
of, in case the electric field strength of a radio station currently being received
has decreased to less than a predetermined level in some way or other, automatically
selecting a radio wave broadcast from another radio station having a higher electric
field strength in the same network, wherein the RDS receiver, in automatically changing
from a radio station currently being received to another radio station broadcasting
the same program, extends or shortens a muting time during which the muting operation
is executed, by controlling a station detector (SD) waiting time, which is a required
period of time until the SD signal becomes high level, in proportion to a difference
between the frequency currently being received and that of another radio station. In order to complete the above object, the RDS receiver according to the present invention comprises a controlling means to calculate a difference between the frequency currently being received and that of another radio station, and controls an SD (station detector) waiting time in proportion to the thus figured-out difference therebetween. |
