1 is a diagram illustrating a broadcast frequency change system according to an exemplary embodiment of the present invention.

Referring to FIG. 1, a broadcast frequency change system includes a broadcast device 100 and a mobile terminal 200 provided in a vehicle.

The broadcast apparatus 100 provided in the vehicle tunes a broadcast channel selected by a listener and outputs a voice corresponding to the tuned broadcast channel. The broadcast device 100 provided in the vehicle is provided with a wireless communication module, and thus performs data communication with the connected mobile terminal 200.

The mobile terminal 200 is connected to the broadcasting device 100 provided in the vehicle to perform data communication.

In particular, the mobile terminal 200 receives the information of the broadcasting channel broadcast by the broadcasting device 100 provided in the vehicle, and when the area where the vehicle is located changes as the vehicle travels, Check the information of the broadcast channel corresponding to the region, and transmits the information of the confirmed broadcast channel to the broadcast device 100 provided in the vehicle.

In this case, the broadcast may include a general TV broadcast and broadcast broadcast, but for the sake of convenience, the broadcast will be described on the assumption that the broadcast is broadcast. However, it will be apparent to those skilled in the art that the broadcasts described below may include not only broadcast broadcasts but also TV broadcasts and Internet broadcasts.

In other words, in general, a broadcast signal transmitted from each broadcasting station propagates to a region of a predetermined range through a transmission station that is set up at a predetermined distance. Signal interference occurs between transmission stations when the same frequency is used for each transmission station. Accordingly, each transmitting station transmits the broadcast signal using different transmission frequencies.

For example, KBS2 FM broadcasting is transmitted at 89.1 MHz in Seoul and Incheon, 91.4 MHz in Gyeonggi, and 85.3 MHz in Gwangju.

Thus, when the listener moves to the Gwangju area while the listener adjusts the tuning frequency of the receiver to 91.4 MHz to listen to the KBS2 FM broadcast in the competition area, the user needs to view the same broadcast in order to watch the same broadcast. You must change the tuning frequency.

Accordingly, the mobile terminal 200 receives information of a broadcast channel (for example, 91.4 MHz of KBS2 FM broadcast) currently broadcasted by the broadcast device 100 provided in the vehicle, and currently receives the information from the vehicle 100. Check the broadcast channel that is being broadcast. Thereafter, the mobile terminal 200 identifies the area where the vehicle is currently located using the received broadcast channel information.

Subsequently, when the vehicle moves, the position of the broadcasting device 100 provided in the vehicle is changed, and when the vehicle moves to the Gwangju region, the mobile terminal 200 previously broadcasts the vehicle 100. Check the broadcast channel information (broadcasting station information and tuning frequency information) necessary for receiving the same broadcast channel as the broadcast channel. In this case, the mobile terminal 200 may confirm that the tuning frequency should be changed to 85.3 MHz in order to listen to the KBS2 FM broadcast in the Gwangju area by using different frequency information for each region previously stored.

Accordingly, the mobile terminal 200 transmits the checked tuning frequency (85.3 MHz) information to the broadcasting apparatus 100 provided in the vehicle, and transmits the information to the tuning frequency transmitted by the broadcasting apparatus 100 provided in the vehicle. Accordingly, the broadcast channel can be changed.

Hereinafter, the broadcast frequency change system will be described in more detail with reference to the accompanying drawings.

2 is a diagram illustrating a broadcast apparatus provided in a vehicle according to an embodiment of the present invention, and FIG. 3 is a diagram illustrating a mobile terminal according to an embodiment of the present invention.

Referring to FIG. 2, the broadcast apparatus 100 provided in the vehicle includes a tuner unit 110, a volume controller 120, a speaker 130, a key input unit 140, a wireless communication unit 150, and a controller 160. It includes.

When the broadcast channel is selected by the listener, the tuner 110 receives a broadcast signal according to a frequency value of the selected broadcast channel according to a control signal of the controller 160, demodulates it, and converts it into an audio signal of a baseband. Output

The volume controller 120 adjusts the audio signal transmitted from the tuner 110 to a volume level set under the control of the controller 160, and then amplifies the audio signal with the adjusted volume level.

The speaker 130 converts the audio signal power amplified by the volume controller 120 into sound waves and outputs the sound waves.

The key input unit 140 is an operation switch for operating the vehicle broadcast apparatus 100 and receives a broadcast channel to be listened to from a listener.

The wireless communication unit 150 performs data communication with the mobile terminal 200 connected by wireless communication. At this time, the wireless communication unit 150 may be implemented as a Bluetooth module.

The wireless communication unit 150 performs a pairing process and connects the Bluetooth communication with the mobile terminal 200 through an authentication and connection process with the mobile terminal 200.

The controller 160 controls the overall operation of the broadcast apparatus 100 provided in the vehicle.

In particular, when the broadcast channel is selected through the key input unit 140, the control unit 160 performs the tuning operation of the tuner unit 110 with a frequency value corresponding to the selected broadcast channel.

Thereafter, the controller 160 outputs the broadcast signal tuned through the tuner 110 through the speaker 130.

In this case, the controller 160 transmits the information corresponding to the selected broadcast channel, that is, the broadcast station information and the broadcast frequency information of the selected broadcast channel through the key input unit 140 to the mobile terminal 200.

In other words, the controller 160 provides the mobile terminal 200 with specific information about which broadcaster the listener is currently listening to in the broadcast apparatus 100 provided in the vehicle.

Thereafter, the controller 160 periodically checks whether broadcast channel information for changing a broadcast frequency is transmitted through the mobile terminal 200.

In this case, the broadcast channel information for changing the broadcast frequency is transmitted when the area where the broadcast apparatus 100 provided in the vehicle is located is changed (when the vehicle moves to another area) due to the driving of the vehicle. .

As described above, since the broadcast channels provided for each region are different, when the currently broadcast channel is changed as the vehicle moves to another region, the controller 160 continues to listen to the broadcast channel originally listened to by the listener. The broadcast channel information to enable the mobile terminal 200 is provided.

To this end, the mobile terminal 200 tracks the position of the broadcast apparatus 100 provided in the vehicle, and accordingly extracts broadcast channel information corresponding to the moved region when the position of the vehicle moves to another region. Accordingly, the broadcast frequency change signal including the extracted broadcast channel information is transmitted to the broadcast apparatus 100 provided in the vehicle.

The controller 160 changes the broadcast channel tuned through the tuner 110 using the transmitted broadcast channel information.

Hereinafter, the operation of the mobile terminal 200 will be described in more detail.

Referring to FIG. 3, the mobile terminal 200 includes a wireless communication unit 210, a location measuring unit 220, a memory unit 230, and a control unit 240. In this case, the mobile terminal 200 may be referred to as a broadcasting frequency changing device, a personal computer capable of wireless communication, a laptop computer, a mobile phone, a smartphone, a digital broadcasting terminal, a personal digital assistant (PDA), a portable multimedia player. And a navigation device.

The wireless communication unit 210 performs data communication with the vehicle 100 to which the Bluetooth communication is connected.

In particular, the wireless communication unit 210 receives information on a broadcast channel currently broadcasted by the broadcast apparatus 100 provided in the vehicle.

In addition, when the vehicle moves to another region, the wireless communication unit 210 transmits a broadcast frequency change signal including broadcast channel information corresponding to the moved region to the vehicle 100.

The position measuring unit 220 receives coordinate data and time data transmitted from a GPS satellite and broadcasts the broadcast device 100, the mobile terminal 200, or the vehicle 100 provided in the vehicle or the vehicle. Measures the current position of the listener listening to the broadcast in real time.

The memory unit 230 stores data necessary for the operation of the mobile terminal 200 or data generated during the operation of the mobile terminal 200.

In particular, the memory unit 230 stores information of broadcast channels different for each region. The broadcast channel information includes broadcast station information and frequency information corresponding to the broadcast station.

area Broadcast stations Broadcast frequency
Seoul
KBS FM1 93.7 MHz KBS AM1 711 MHz MBC AM 900 MHz
Gwangju
KBS FM1 90.5 MHz KBS AM1 747 MHz MBC AM 819 MHz

As shown in Table 1, the memory unit 230 stores broadcast frequency information for listening to a broadcast broadcast corresponding to each broadcast station for each region.

The controller 240 controls the overall operation of the mobile terminal 200.

In particular, when the broadcast channel information is received through the wireless communication unit 210, the controller 240 determines an area where the broadcast apparatus 100 currently provided in the vehicle is located using the received broadcast channel information.

For example, when the received broadcast channel information is 'KBS FM 1', '93 .7MHz, the controller 240 confirms that the vehicle is currently located in the Seoul area.

Subsequently, the controller 240 determines whether the location of the vehicle, more specifically, the area where the broadcasting apparatus 100 provided in the vehicle is located, is changed by using the location information measured by the location measuring unit 220. . In other words, the controller 240 checks whether the current location measured in real time is an area other than the identified Seoul area.

If the area where the broadcast apparatus 100 provided in the vehicle is located is changed, the controller 240 extracts broadcast information corresponding to the changed area from the memory unit 230.

In other words, if the area in which the broadcasting device 100 is located is changed to the Gwangju area, the controller 240 checks frequency information for each broadcaster provided by the Gwangju area.

Thereafter, the controller 240 extracts frequency information corresponding to the previously received broadcaster from the checked frequency information for each broadcaster. For example, since broadcasting station information 'KBS FM1' has been transmitted through the broadcasting apparatus 100 provided in the vehicle, the controller 240 checks frequency information providing 'KBS FM1' in the Gwangju region.

When the frequency information of 'KBS FM1' corresponding to the Gwangju region is confirmed, the controller 240 compares the frequency information of 'KBS FM1' corresponding to the Seoul region previously, and if the two frequency information are the same The current state is maintained.

However, if the frequency information of 'KBS FM1' corresponding to the Gwangju region and the frequency information of 'KBS FM1' corresponding to the Seoul region are different from each other, the control unit 240 of the 'KBS FM1' corresponding to the Gwangju region is different. The frequency information is transmitted to the broadcast apparatus 100 provided in the vehicle.

In other words, since the area in which the vehicle is currently located is changed, the control unit 240 transmits information to the broadcasting apparatus 100 provided in the vehicle to change the tuning frequency of '90 .5 MHz 'in order to continue watching the' KBS FM1 'broadcast. do.

Accordingly, the broadcast apparatus 100 performs a channel tuning operation using the information transmitted through the mobile terminal 200, so that the 'KBS FM1' broadcast is continuously provided to the listener.

Alternatively, the broadcast apparatus 100 may output a guide message indicating that the tuning frequency should be changed to 90.5 MHZ in order to continue watching the 'KBS FM1' broadcast, thereby inducing the listener to change the tuning frequency.

As described above, according to the exemplary embodiment of the present disclosure, the driver may skip the search and selection of the broadcasting frequency due to different broadcasting frequencies for each region moving in the vehicle driving, thereby increasing the ease of use and increasing the stability.

4 is a flowchart for explaining a method of changing a frequency of a broadcasting frequency changing system according to an embodiment of the present invention step by step.

Referring to FIG. 4, first, the broadcast apparatus 100 and the mobile terminal 200 provided in a vehicle perform a pairing operation to connect Bluetooth communication (step 100). The pairing operation may be divided into an authentication process and a connection process.

Thereafter, the broadcast apparatus 100 receives a broadcast signal of a specific broadcast channel selected by the listener and outputs the received broadcast signal (step 110).

In addition, the broadcast apparatus 100 transmits information on the output broadcast signal, that is, information on a broadcast channel selected from the listener, to the mobile terminal 200 through the connected Bluetooth communication (step 120).

Thereafter, the broadcast device 100 continuously moves as the vehicle travels (step 130).

In this case, when the broadcast information is received, the mobile terminal 200 identifies a region where the vehicle is currently located by using broadcast station information and frequency information included in the received broadcast information.

The region may be identified using previously stored broadcasting channel information for each region.

For example, as shown in Table 1, when the broadcasting station information included in the received broadcasting channel information is 'KBS FM1' and the frequency information is '93 .7 MHz, the mobile terminal 200 currently operates the vehicle. You can see that it is located in the Seoul area.

Thereafter, the mobile terminal 200 determines whether the area where the broadcasting device 100 provided in the vehicle is located is changed by using the location data and the time data received from the satellite (step 140).

In other words, the mobile terminal 200 checks whether the location information measured in real time is an area other than the identified Seoul area.

If the area in which the broadcasting device 100 provided in the vehicle is located is changed from the Seoul area to another area, the mobile terminal 200 extracts broadcast information corresponding to the changed area (step 150).

In other words, if the area where the broadcasting device 100 is located is changed to the Gwangju area, the mobile terminal 200 checks the frequency information for each broadcaster provided by the Gwangju area.

Thereafter, the mobile terminal 200 extracts frequency information corresponding to the previously received broadcaster from the checked frequency information for each broadcaster. For example, since broadcasting station information 'KBS FM1' has been transmitted through the broadcasting apparatus 100 provided in the vehicle, the mobile terminal 200 checks frequency information of 'KBS FM1' corresponding to the Gwangju region. .

When the frequency information of 'KBS FM1' corresponding to the Gwangju area is confirmed, the mobile terminal 200 compares the frequency information of 'KBS FM1' corresponding to the Seoul area with each other, and the two frequency information are identical to each other. In this case, it is maintained.

However, if the frequency information of 'KBS FM1' corresponding to the Gwangju area and the frequency information of 'KBS FM1' corresponding to the Seoul area are different from each other, the mobile terminal 200 corresponds to the 'KBS FM1' corresponding to the Gwangju area. The frequency information is transmitted to the broadcasting device 100 provided in the vehicle (step 160).

In other words, since the current location of the vehicle is changed, the mobile terminal 200 transmits information to the broadcasting apparatus 100 provided in the vehicle to change the tuning frequency to 90.5 MHz in order to continue watching the 'KBS FM1' broadcast. do.

Accordingly, the broadcast apparatus 100 performs a channel tuning operation using the information transmitted through the mobile terminal 200, so that the 'KBS FM1' broadcast is continuously provided to the listener (step 170).

Alternatively, the broadcast apparatus 100 may output a guide message indicating that the tuning frequency should be changed to 90.5 MHz in order to continue watching the 'KBS FM1' broadcast, thereby inducing the listener to change the tuning frequency.

Meanwhile, the mobile terminal may be applied to any device equipped with a wireless communication module among a personal computer, a notebook computer, a mobile phone, a smartphone, a digital broadcasting terminal, a personal digital assistant (PDA), a portable multimedia player, and a navigation device. It is possible.

As described above, according to the exemplary embodiment of the present disclosure, the driver may skip the search and selection of the broadcasting frequency due to different broadcasting frequencies for each region moving in the vehicle driving, thereby increasing the ease of use and increasing the stability.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be understood that various modifications and applications other than those described above are possible. For example, each component specifically shown in the embodiments of the present invention can be modified and implemented. It is to be understood that all changes and modifications that come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
