Abstract

A radio system includes an audio device, and a control device operatively connected to the audio device to store a first radio frequency of the audio device as a preset frequency, wherein the control device may be configured to determine whether a second broadcast signal received through a second radio frequency is equal to a first broadcast signal received through the first radio frequency stored in a preset list when the second radio frequency of the audio device is added as the preset frequency, generate the preset list including the first and second radio frequencies when the first broadcast signal is different from the second broadcast signal, and generate the preset list including the first or second radio frequency when the first and second broadcast signals are broadcast signals of a same radio broadcast.

First claim

What is claimed is:

1 . A radio system comprising:
an audio device; and a control device operatively connected to the audio device to store a first radio frequency of the audio device as a preset frequency, wherein the control device is configured to:
determine whether a second broadcast signal received through a second radio frequency is equal to a first broadcast signal received through the first radio frequency stored in a preset list in response that the second radio frequency of the audio device is added as the preset frequency,
generate the preset list including the first radio frequency and the second radio frequency in response that the first broadcast signal is different from the second broadcast signal, and
generate the preset list including the first radio frequency or the second radio frequency in response that the first broadcast signal and the second broadcast signal are broadcast signals of a same radio broadcast,
wherein the control device is further configured to:
select the second radio frequency corresponding to the second broadcast signal having a reception sensitivity higher than or equal to a reference sensitivity while changing the first radio frequency at a predetermined interval; and
add the selected second radio frequency as the preset frequency.

2 . The radio system of claim 1 , wherein the control device is further configured to:
output a user interface operatively connected to the control device for radio frequency selection; and change the first radio frequency to the second radio frequency based on an input to the user interface and add the changed second radio frequency as the preset frequency.

3 . The radio system of claim 1 , wherein the control device is further configured to:
upon concluding that the first broadcast signal and the second broadcast signal are broadcast signals of the same radio broadcast, obtain location information related to a vehicle, and generate the preset list by selecting one of the first radio frequency or the second radio frequency based on the location information.

4 . The radio system of claim 1 ,
wherein the control device is further configured to:
check at least one preset frequency related to a broadcast signal having a reception sensitivity less than a reference sensitivity in the preset list in response that movement of a vehicle is detected; and
change the at least one preset frequency to an alternative frequency, and
wherein the alternative frequency includes another radio frequency through which the same radio broadcast as a radio broadcast received through the at least one preset frequency is transmitted.

5 . The radio system of claim 4 , wherein the control device is further configured to:
obtain information on the alternative frequency associated with the at least one preset frequency from inside the radio system or outside the radio system.

6 . The radio system of claim 4 , wherein the control device is further configured to:
check a current location of the vehicle; and check the information on the alternative frequency corresponding to the current location of the vehicle.

7 . The radio system of claim 1 ,
wherein the control device is further configured to:
check an inaudible preset frequency related to a moving path of a vehicle from the preset list; and
change the inaudible preset frequency to a predetermined radio frequency, and
wherein the predetermined radio frequency includes audible radio frequencies of other radio broadcasts on the moving path.

8 . The radio system of claim 7 , further including:
a display operatively connected to the control device and configured to output the preset list, wherein the control device is further configured to output the inaudible preset frequency in a first scheme and output other preset frequencies excluding the inaudible preset frequency in a second scheme in the preset list output to the display.

9 . The radio system of claim 7 , further including:
an input device operatively connected to the control device, wherein the control device is further configured to change the inaudible preset frequency selected through the input device to the predetermined radio frequency.

10 . A method of operation a radio system, the method comprising:
storing, by a control device of the radio system, a first radio frequency of an audio device as a preset frequency; determining, by the control device, whether a second broadcast signal received through a second radio frequency is equal to a first broadcast signal received through the first radio frequency stored in a preset list in response that the second radio frequency of the audio device is added as the preset frequency; generating, by the control device, the preset list including the first radio frequency and the second radio frequency in response that the first broadcast signal is different from the second broadcast signal; generating, by the control device, the preset list including the first radio frequency or the second radio frequency in response that the first broadcast signal and the second broadcast signal are broadcast signals of a same radio broadcast; selecting, by the control device, the second radio frequency corresponding to the second broadcast signal having a reception sensitivity higher than or equal to a reference sensitivity while changing the first radio frequency at a predetermined interval; and adding, by the control device, the selected second radio frequency as the preset frequency.

11 . The method of claim 10 , further including:
outputting, by the control device, a user interface operatively connected to the control device for radio frequency selection; and changing, by the control device, the first radio frequency to the second radio frequency based on an input to the user interface and adding the changed second radio frequency as the preset frequency.

12 . The method of claim 10 , further including:
upon concluding that the first broadcast signal and the second broadcast signal are broadcast signals of the same radio broadcast, obtaining, by the control device, location information related to a vehicle, and generating, by the control device, the preset list by selecting one of the first radio frequency or the second radio frequency based on the location information.

13 . The method of claim 10 , further including:
checking, by the control device, at least one preset frequency related to a broadcast signal having a reception sensitivity less than a reference sensitivity in the preset list in response that movement of a vehicle is detected; and changing, by the control device, the at least one preset frequency to an alternative frequency, wherein the alternative frequency includes another radio frequency through which the same radio broadcast as a radio broadcast received through the at least one preset frequency is transmitted.

14 . The method of claim 13 , further including:
obtaining, by the control device, information on the alternative frequency associated with the at least one preset frequency from inside the radio system or outside the radio system.

15 . The method of claim 13 , further including:
checking, by the control device, a current location of the vehicle; and checking, by the control device, the information on the alternative frequency corresponding to the current location of the vehicle.

16 . The method of claim 10 , further including:
checking, by the control device, an inaudible preset frequency related to a moving path of a vehicle from the preset list; and changing, by the control devic
