The present invention relates to a vehicle advertising system, and more particularly to a location-based local advertising system.

A vehicle is a vehicle for carrying people or things. Such vehicles include cars, trains, ships, and aircraft. Among the vehicles, buses, trains, ships, and airplanes are public transportation used by many people.

Public transportation has been widely used as a platform for commercial advertising because it is used by many people. For example, buses and subways display advertisements to passengers with printed advertisements on the walls.

Such static advertising has a limitation in that the advertising shown is static and the update of the advertisement is not quick.

Therefore, a dynamic advertising method for public transportation was introduced. For example, a subway car is provided with a liquid crystal display, and shows a broadcast program through the liquid crystal display, and displays a commercial advertisement in the middle of the broadcast program. However, subway advertisements provide general advertisements irrespective of the location of the passenger car, and these advertisements have a low incentive for passengers to directly purchase advertising items compared to the advertising costs.

Therefore, a location-based advertising method is required, and a lot of location-based advertising methods have been studied. For example, Korean Patent Laid-Open Publication No. 2004-99030 discloses a location-based advertising system using a conventional vehicle advertising terminal.

1 illustrates an advertisement system using an advertisement terminal of a commercial vehicle.

The search condition may be differently selected according to the region where the vehicle 101 is located, and the search condition is previously transmitted from the vehicle information center 113 and stored in the memory 201. For example, if the search condition is set to time in the area A, when the vehicle 101 passes the area A, different advertisements are extracted and displayed according to time. The advertisement information extractor 315 extracts advertisement information corresponding to the positional information and the moving direction of the vehicle 101 according to the search condition extracted by the search condition extractor 313. When the advertisement information extracted by the advertisement information extracting unit 315 has a plurality of advertisement information determiner 317, the advertisement ranking determiner 317 determines the advertisement display rank according to the advertisement effect, the advertisement cost, and the response of the advertisement target. The advertisement information display unit 319 displays advertisement information selected by the advertisement information extraction unit 315 and the advertisement ranking determiner 317 through a display device such as an LCD.

The vehicle related information providing module 305 includes a driving distance calculator 321, a cumulative driving distance calculator 323, a vehicle related information extractor 325, a vehicle related information display 327, and the like. When the location information and time of the vehicle 101 are determined from the GPS satellite 105 at a predetermined time (for example, one second) by the location information receiving unit 309, the travel distance calculation unit 321 may determine the location information. And the travel distance of the vehicle 101 using the time.

The cumulative travel distance calculator 323 calculates the cumulative travel distance by summing the travel distances for each predetermined time calculated by the travel distance calculator 321. The vehicle related information extraction unit 325 extracts vehicle related information (consumables, inspection items, etc.) corresponding to the accumulated travel distance calculated by the cumulative travel distance calculation unit 323 from the memory 201. The vehicle related information display unit 327 provides the vehicle related information extracted by the vehicle related information extraction unit 325 as text, voice, video, and the like. For example, if the cumulative travel distance reaches 8000 km, you can provide the message "It's time to change tires." The driving related information providing module 307 may include a driving related information extracting unit 329 and a driving related information display unit 331. When the location information, the time, and the moving direction are determined by the GPS information module 301, the driving related information extracting unit 329 extracts driving related information corresponding to the location information and the moving direction of the vehicle 101. The driving related information display unit 331 displays the driving related information extracted by the driving related information extracting unit 329 as a buzzer, a text, a voice, a video, and the like.

As described above, according to the vehicle advertisement method using the position information, advertisements corresponding to the position information of the vehicle and the direction and time of the vehicle can be provided to the passenger.

However, such a conventional method may make the passenger bored because only the advertisement is displayed on the display device. Passengers can easily become bored for advertisements that are continuously served from a single monitor, and as a result, passengers can turn away the advertisements. In addition, the conventional method updates the advertisement using only mobile communication when updating the advertisement data. In the case of mobile communication, it is difficult to simultaneously update advertisements for a large number of vehicles because of the point connection method. In addition, the data transmission method is very expensive through mobile communication, and according to this conventional method, the cost of updating the advertisement may be much higher than the effect of the advertisement. Therefore, it is difficult to apply the conventional method to the public transportation system.

Therefore, there is a need for incentives for passengers to be interested in advertising, and a low cost is needed for an advertising method that can simultaneously update advertisements for a large number of vehicles.

As an incentive for passengers to be interested in advertisements, there is a method of displaying broadcasting contents such as dramas and movies and inserting advertisements in the middle of the broadcasting contents, as in the conventional television broadcasting. However, in such a case, there is a problem that the time for providing an advertisement is shortened and that it is difficult to provide a location-based advertisement because the advertisement time is determined.

3 is a block diagram showing the configuration of a vehicle advertising system using a dual monitor according to an embodiment of the present invention.

The vehicle advertisement system 300 includes a processor 310, a monitor controller 330, a storage 340, a location information receiver 350, and a digital broadcast receiver 360.

The processor 310 receives the location information of the vehicle from the location information receiver 350 and selects a local advertisement corresponding to the location information from the storage 340. In addition, the processor 310 stores the new local advertisement data received by the digital broadcast receiver 360 in the storage 340.

The storage 340 stores at least one local advertisement data and stores local advertisement condition data indicating a condition under which each local advertisement is selected. In this specification, a local advertisement means an advertisement provided based on a location. In one embodiment, the local advertisement data includes video data coded in an H.264 manner. If the local advertisement data is coded video data, the processor 310 may perform a process of decoding the coded video data for the selected local advertisement. The local advertisement condition data includes a list of stored local advertisements and location information on which a local advertisement is to be selected.

The location information receiver 350 provides location information regarding the current location and the heading of the vehicle advertising system 300, that is, the vehicle. In one embodiment, the location information receiver 350 receives location information from a satellite navigation support system such as Global Positioning System (GPS) in the United States, Glonass in Russia or Galileo in the European Union. However, the location information receiver 350 may receive location information from a location service system based on a ground infrastructure such as a mobile communication network.

The digital broadcast receiver 360 receives the digital broadcast and reconstructs the broadcast content in the received digital broadcast. Reconstructing broadcast content refers to decoding a coded audio signal, a coded video signal, and a coded text signal when receiving a digital broadcast including a coded audio signal, a coded video signal, and a coded text signal. It means to obtain a signal, a video signal and a text signal, and restore the broadcast content (drama, movie, news, advertisement, etc.) in synchronization with the audio signal, the video signal, and the text signal.

The monitor controller 330 allows the selected local advertisement and broadcast content to be displayed on different monitors. For example, the monitor controller 330 may provide broadcast content to the first monitor 370 and provide local advertisements to the second monitor 380.

  In addition, the monitor controller 330 may provide broadcast content to the second monitor 380 and provide local advertisements to the first monitor 370.

At this time, the passenger of the vehicle may watch one of the broadcast content and the local advertisement, and may alternately watch the both. In general, among broadcast content and local advertisements, passengers are more interested in broadcast content. Therefore, incentives are needed to focus the passenger's interest in local advertising, which is handled by the monitor controller 330.

The monitor controller 330 may focus the passenger's attention on the local advertisement by changing data provided to the first monitor 370 and the second monitor 380 at regular time intervals.

For example, the monitor controller 330 provides broadcast content to the first monitor 370 and local advertisements to the second monitor 380, and then provides broadcast content to the second monitor 380 after 10 minutes. And provide a local advertisement to the first monitor 370. After another 10 minutes, the monitor controller 330 again provides broadcast content to the first monitor 370 and provides local advertisements to the second monitor 380. As such, the monitor controller 330 may change the data provided to the first monitor 370 and the second monitor 380 at regular time periods to prevent the passenger from focusing attention on any particular monitor.

In addition, when a specific event occurs, the monitor controller 330 may focus the passenger's attention on the local advertisement by changing data provided to the first monitor 370 and the second monitor 380.

For example, the monitor controller 330 provides broadcast content to the first monitor 370 and local advertisements to the second monitor 380, and the content of the broadcast content is advertised in a program such as drama, movie, or news. The broadcast content is provided to the second monitor 380 and the local advertisement is provided to the first monitor 370 at the moment it changes to. In one embodiment, when the advertisement is over and the broadcast content is changed back to a program such as drama, movie or news, the monitor controller 330 again provides the broadcast content to the first monitor 370 and the second monitor 380. ) Can provide local ads. In another embodiment, the monitor controller 330 provides the broadcast content to the second monitor 380 and localized to the first monitor 370 even after the advertisement is finished and the broadcast content is changed back to a program such as drama, movie or news. Providing Advertisement When the broadcast content is changed into an advertisement again, the broadcast content may be provided to the first monitor 370 and the local advertisement may be provided to the second monitor 380.

As such, when a specific event occurs, the monitor controller 330 may change data provided to the first monitor 370 and the second monitor 380 to prevent a passenger from focusing attention on a specific monitor. .

For example, the monitor switching unit 431 may provide broadcast content to the first monitor 470 and local advertisements to the second monitor 480, or vice versa.

The monitor switching unit 431 changes the monitor on which the broadcast content and the local advertisement are displayed when the monitor change condition is satisfied. For example, if the monitor change condition is satisfied while providing the broadcast content to the first monitor 470 and the local advertisement to the second monitor 480, the monitor switching unit 431 provides the broadcast content to the second monitor ( 480, and the local advertisement is provided to the first monitor 470.

The change condition controller 432 checks whether the monitor change condition is satisfied, and informs the monitor switching unit 431 that the monitor change condition is satisfied when the monitor change condition is satisfied. In one embodiment, the change condition controller 432 informs the monitor switching unit 431 that the monitor change condition is satisfied at a preset time interval. In another embodiment, the change condition controller 432 determines that the monitor change condition is satisfied at the time when the content of the broadcast content is changed into an advertisement, and informs the switching unit 431 that the monitor change condition is satisfied.

In relation to the method of identifying the content of the broadcast content, Korean Patent Laid-Open Publication No. 2004-106500 discloses a technique for identifying content in a digital video recorder, and Korean Patent Laid-Open Publication No. 2004-0091740 discloses a technique for skipping an advertisement part. Korean Patent Laid-Open Publication No. 2003-0029906 discloses a technique of displaying another advertisement instead of the original advertisement. Such various technologies may detect a time point at which broadcast content is changed into an advertisement.

The change condition controller 432 checks a point in time at which the content of the digital broadcast is changed into an advertisement and informs the monitor switching unit 431. The monitor switching unit 431 changes the monitor displaying the broadcast content and the local advertisement so that the user broadcasts. Reduce focus on monitors that display content.

The GPS signal receiver 451 receives a GPS signal provided by a GPS satellite. GPS signals are carried on L1 signals at 1.575.42 MHz and L2 signals at 1.227.60 MHz. The L1 signal carries the navigation message and the C / A code signal, and the L2 signal is used to measure the delay occurring in the ionosphere.

The location information calculator 452 calculates location information such as a current vehicle position and a traveling direction speed by using the received GPS signal.

The storage 440 stores a local advertisement list including local advertisement data and location information on which local advertisements are displayed, and a region code map having region codes for each region and each region. The storage 440 may be implemented as a nonvolatile storage medium such as a hard disk or a flash memory.

The components of the in-vehicle advertising system may be combined into a smaller number of higher components or each component may be divided into lower components.

5 is a flowchart illustrating a local advertisement display process of the vehicle advertisement system according to an embodiment of the present invention.

First, when the power is supplied to the vehicle advertisement system, the vehicle advertisement system is booted (S510).

When the vehicle advertisement system boots, the basic advertisement is selected and displayed on the first monitor or the second monitor (S520). At this time, the broadcast content is displayed on the second monitor or the first monitor.

The vehicle advertisement system receives location information to select a local advertisement (S530).

When the location of the current vehicle is calculated based on the location information, the vehicle advertisement system determines whether there is a local advertisement matching the current location (S540).

If there is no local advertisement matching the current location, the vehicle advertisement system displays the basic advertisement as it is (S520).

If there is a local advertisement matching the current location, the vehicle advertising system stops displaying the basic advertisement (S550), and displays the local advertisement matching the current location (S560). As described above, a process of selecting a local advertisement matching the current location in order to display the local advertisement matching the current location will be described later with reference to FIGS. 6 and 7.

The vehicle advertisement system checks whether the advertisement matching the current position ends (S570), and then displays the stopped basic setting advertisement from the portion where the advertisement stopped when the advertisement matching the current position ends (S580). The steps S530 to S580 are repeated while displaying the basic advertisement.

The in-vehicle advertising system subsequently displays the stopped default advertisement in step S580 but may display the stopped default advertisement from the beginning or the next default advertisement. In the present specification, the default advertisement refers to a basically displayed advertisement that is displayed when there is no local advertisement mapped to the current location. For example, the basic setting advertisement may include weather information of the region where the vehicle is currently located or information provided by the local government where the vehicle is currently located.

6 is a flowchart illustrating a process of selecting a local advertisement based on a location according to an embodiment of the present invention.

The vehicle advertising system recognizes the current position and direction of the vehicle from the location information (S610). Then, the vehicle advertising system checks the position of the nearest local advertisement at a position ahead of the current vehicle in the local advertisement list (S620). The nearest local advertisement refers to a local advertisement that should be displayed first in the direction of travel from the current vehicle position.

The vehicle advertising system determines whether the current location and the location of the nearest local advertisement are the same (S630). The fact that the current location and the nearest local advertisement have the same position means that the current location and the nearest local advertisement are within a preset error range. For example, the in-vehicle advertising system may determine that the two locations are the same when the location of the nearest local advertisement is within 500 meters from the current location.

When the location of the nearest local advertisement becomes the same from the current location, the vehicle advertisement system selects and displays the nearest local advertisement (S640).

7 is a flowchart illustrating a process of selecting a local advertisement based on a location according to another embodiment of the present invention.

In the embodiment of FIG. 6, the area of the area where the local advertisement is selected may not be differentially provided, but according to the embodiment of FIG. In order to differentially give an area of an area where a local advertisement is selected, the embodiment of FIG. 7 introduces the concept of a region code. The area code will be described later with reference to FIG. 8.

The vehicle advertising system finds a region code mapped to the current location (S710). Then, the vehicle advertising system checks whether there is a local advertisement matching the current region code in the local advertisement list (S720).

If there is no local advertisement matching the current area code, the vehicle advertising system repeats steps S710 to S730. Since the vehicle moves, repeating steps S710 to S730 results in a local advertisement matching the current region code.

The vehicle advertisement system selects and displays a matched local advertisement when there is a local advertisement matched with the current region code (S730).

8 is a diagram for describing a hierarchical area code according to an embodiment of the present invention.

For the area code map 800 for any wide area, the area code is assigned to A, B, C, D, E, F, G, H or I for each area.

A region code is assigned to Aa, Ab, Ac, Ad, Ae, Af, Ag, Ah, or Ai for each region of region code map 810 for the region covered by region code A.

The area codes for each area of the area code map 810 all contain "A". That is, when region code A is called a parent region code, each sub region code mapped to sub regions belonging to a region (upper region) that is mapped to a parent region code A is a parent code "A" and each sub region code. It includes the identification code of a, b, c, d, e, f, g, h or i.

Region codes are assigned to Ac1, Ac2, Ac3, Ac4, Ac5, Ac6, Ac7, Ac8 or Ac9 for each region of region code map 820 for the region covered by region code Ac.
