Description

  The present invention relates to an information processing technique for enabling an information terminal to receive a broadcast wave when it exists in a limited area.

  Television broadcasting in Japan ended analog broadcasting in 2011 and completely shifted to digital broadcasting. Along with that, users have responded by replacing TV receivers with devices compatible with digital broadcasting and installing special tuners on receivers compatible with analog broadcasting.

With the development of information technology, not only voice data called telephones but also digitized data such as characters, images and music are sent and received on public telephone lines.
In addition, with the spread and miniaturization of information terminals, transmission / reception of digitized data can be performed with portable information terminals represented by smartphones.

Electronic devices for utilizing GPS (Global Position System) have been miniaturized and used as car navigation systems.
The GPS function has also been installed in portable information terminals, digital cameras, watches, and the like, and is used to provide various services to users of such devices and to collect marketing data.

Now, it has become widespread to install digital broadcast receivers in vehicles. In that case, when a vehicle equipped with a digital broadcast receiving device moves, it may be accompanied by a function of performing a channel seek or channel scan on a one-segment broadcast station where the broadcast area is limited.
Patent Document 1 discloses a technique that can prevent the inconvenience that a broadcast station for area-limited one-segment broadcasting is wasted for such a vehicle-mounted terrestrial digital broadcast receiver.

Patent Document 2 discloses a technology that realizes an inexpensive right protection function with a simple configuration for copyright management of broadcast content in which data does not deteriorate in terrestrial digital broadcasting.
Paying content is difficult except for extremely attractive content, so pay broadcasts remain limited. Therefore, even now that the broadcasting has been converted from analog to digital, the majority of the free broadcasting is in exchange for inviting consumption of sponsor products and services.

JP 2010-226207 A JP 2012-54979 A

Now, with the shift to terrestrial digital broadcasting, the band (VHF band) used for analog broadcasting becomes vacant, and its utilization method is discussed.
However, the current broadcast wave only distributes contents such as TV programs and radio programs all at once.

  On the other hand, broadcasting effective for inducing consumption of products and services is desired to be broadcast to a limited area that is closely related to the target products and services. For example, it is less likely to lead to consumption unless it is broadcast to a viewer who can purchase a target product or receive a target service near a store or base.

For example, in the case of a broadcast receiver installed in a general household, if a reception target device is designated for distribution to a limited area, it is possible to receive an analog broadcast for the limited area.
However, when the in-vehicle device or the portable information terminal is a broadcast receiver, it is assumed that the vehicle is moving, and therefore the current position cannot be specified, and the device to be received cannot be specified.

  The problem to be solved by the present invention is to provide a technology that makes it possible to receive a broadcast wave in a limited area for a portable information terminal or an information terminal mounted on a mobile object.

  In order to solve the above-described problems, the present application grasps the current position of a portable information terminal or an information terminal mounted on a mobile body, determines whether the current position is a limited area for content distribution, In the case of an area, an invention is provided in which content distribution via broadcast waves is executed.

Hereinafter, the present invention will be described based on embodiments. The drawings used here are FIGS. 1 to 11.
In the following embodiments, a smartphone with a GPS function and a car navigation device are employed as the information terminal.

(Figure 1)
FIG. 1 shows an image in which a smartphone and an in-vehicle device receive radio broadcast from a radio tower in a band (VHF band) used for analog broadcast. Smartphones and in-vehicle devices are equipped with a receiving tuner.
Here, the “reception tuner” is a tuner capable of receiving a broadcast wave, and a channel can be selected when it corresponds to a broadcast transmitted from a plurality of broadcast stations.

Radio waves transmitted from the radio tower include content data and distribution area data in broadcast waves.
Here, “content data” refers to video and audio introducing service contents at a store, electronic coupons for obtaining various privileges for services at a store, and the like.
In addition, “distribution area data” is data for specifying a distribution area in which content data included in a broadcast wave is to be output, and a latitude and longitude regarding a predetermined center and a radius distance from the center. including.

  Instead of “latitude and longitude” regarding a predetermined center, spots such as landmark buildings (for example, Tokyo Tower) and historic sites (relaxation of Ryoma Sakamoto) may be used. For such spots, the latitude and longitude are calculated by another software.

(Figure 2)
FIG. 2 shows a control algorithm related to whether or not to output content data using distribution area data and position data from GPS. This control algorithm is executed by “control means” in FIGS. 3 to 9 described later.
First, the reception tuner receives a broadcast wave including content data and distribution area data.
On the other hand, the current position data of the information terminal is acquired by the GPS built in the information terminal connected to the receiving tuner.

Subsequently, a distance between the two points is calculated from the central latitude in the distribution area and the latitude in the current position data, and the central longitude in the distribution area and the longitude in the current position data. Then, it is determined whether or not the linear distance from the center to the current position in the distribution area is within the distribution area.
When the current position is within the distribution area, the output device (liquid crystal screen, speaker, etc.) of the information terminal is controlled and a signal for outputting content data is transmitted. When the current position is not within the distribution area, control is performed so that the content data is not output from the output device of the information terminal.

As described above, when a moving information terminal exists in a limited area, content via broadcast waves can be output. This function provides the following advantages.
For example, a person who provides a service at a certain store or base is a content data provider (sponsor). Then, the content data can be provided only to the information terminal located at a distance that is likely to be visited by going to the store or base.
Since the content data is output only to the person existing at that time in the area specified by the distribution area data, the content data that is unlikely to stop (unnecessary) may be output from the information terminal. This contributes to reducing the annoyance for the information terminal user.

(Figure 3)
FIG. 3 illustrates an embodiment in which broadcast data from a radio tower can be received by connecting a reception tuner to an existing information terminal (for example, a smartphone). The connection between the information terminal and the reception tuner may be either a wired connection or a wireless connection, but in FIG. 3, it is illustrated as a “wireless connector”.
The receiving tuner in the embodiment shown in FIG. 3 includes content receiving means, and the above-described distribution area data is received by the data receiving means in the information terminal.
In order to receive the distribution area data at the information terminal and use it for subsequent processing, a dedicated application is downloaded in advance. For example, when the information terminal is connected to the receiving tuner, the application prompts the user to activate the GPS function (which is turned off).

The distribution area data received by the data receiving means is processed by the control means together with the current position data from the GPS built in the information terminal in advance. The processing algorithm is the same as the procedure described with reference to FIG.
The content data received by the content receiving means of the receiving tuner receives output control data from the control means and is output at the output means. The output means is a liquid crystal screen or a speaker.

  In the case where the information terminal is a car navigation device, control is performed so that content data is not output from the output means when the vehicle is not in a state in which a person is in the car on which the car navigation device is mounted and the engine is started. The control means executes.

(Fig. 4)
In the embodiment shown in FIG. 4, a reception tuner including distribution area data reception means in addition to the content reception means is adopted, and such reception tuner is connected to the information terminal. 4 to 9 and FIG. 11, the connection between the reception tuner and the information terminal may be either wired communication or wireless communication, and is not shown.

  The receiving tuner according to this embodiment receives distribution area data as well as broadcast data from a radio tower. The received distribution area data is processed by the control means together with the current position data from the GPS built in the information terminal in advance. In order to receive the distribution area data at the information terminal and use it for the subsequent processing, a dedicated application is downloaded in advance as in the embodiment of FIG.

(Fig. 5)
In the embodiment shown in FIG. 5, the receiving tuner and the information terminal are the same as the embodiment shown in FIG. The difference is that the distribution area data is transmitted (broadcast) to the information terminal, not the radio tower, but a reception area control server provided separately from the radio tower.

If the operator that stores, manages, and broadcasts the content data is different from the operator that stores, manages, and broadcasts the distribution area data, the operations may be performed as in this embodiment. is there.
Although illustration is omitted, the receiving tuner and the information terminal may have the same configuration as that of the embodiment shown in FIG.

(Fig. 6)
The embodiment shown in FIG. 6 includes a storage unit that can store content data in the reception tuner. Although the reception tuner in other embodiments is also provided with a random access memory, the “storage means” intended by this embodiment is a storage means having a storage capacity capable of storing a large amount of data that cannot be stored in the random access memory. Assumed.
Other configurations are the same as those of the embodiment shown in FIG.

According to this embodiment, it is possible to greatly shift the timing of receiving broadcast data from the radio tower and the timing of outputting content data by the output means.
For example, when the information terminal in this embodiment is a car navigation device, broadcast data is received in a time zone in which an automobile equipped with the car navigation device is parked. The output means can output the content data at the timing when the vehicle is traveling in the area to be output. This is effective when there are many types and volumes of content data to be output or when there are a plurality of areas.

(Fig. 7)
The embodiment shown in FIG. 7 employs a reception tuner that can perform up to the content data output control function.
That is, the receiving tuner includes a control unit in addition to the content receiving unit and the distribution area data receiving unit. Current position data is input from the GPS of the information terminal connected via wireless communication or a connector (not shown), and output control data for the output means of the information terminal is transmitted using the distribution area data.

  In FIG. 7, the control means is indicated by a broken line, but this does not mean that the control means is not provided. When the information terminal is a smartphone, it is possible to reduce the load on main components such as a CPU that performs control means.

(Fig. 8)
The embodiment shown in FIG. 8 employs a reception tuner that can handle the acquisition of current position data by providing a GPS in addition to the output control function of content data.
That is, the reception tuner includes a control unit and a GPS in addition to the content reception unit and the distribution area data reception unit. In FIG. 8, the control means and the GPS are indicated by broken lines, but this does not mean that they are not provided.

If the information terminal is a car navigation device, it is essential to install GPS, and most other portable information terminals are also equipped with a GPS function.
However, in the case of a portable information terminal, there is a user who keeps the GPS function cut off in order to protect personal information and suppress battery consumption. When such a portable information terminal related to the user is connected to the reception tuner, the current position data can be acquired by the GPS on the reception tuner side without prompting the user via the application to activate the GPS function.

(Fig. 9)
The embodiment shown in FIG. 9 employs a reception tuner that can handle the output of content data by providing output means in addition to the content data output control function.
That is, the receiving tuner includes a control unit and an output unit in addition to the content receiving unit and the distribution area data receiving unit. In FIG. 9, although the output means and the control means are indicated by broken lines, this does not mean that they are not provided.

  In the embodiment shown in FIG. 9, the only function that depends on the information terminal by connecting to the information terminal is GPS, and the current position data is acquired from the GPS. Since output means such as a liquid crystal screen and a speaker are provided on the reception tuner side, output of text data, still images, moving images, audio, etc. as content data can be performed in the reception tuner.

  The receiving tuner in the embodiment shown in FIG. 3 to FIG. 9 is more preferably provided with a power source different from the information terminal, although not shown. This is because when the information terminal is a smartphone, battery consumption of the smartphone is minimized in a situation where the smartphone cannot be used while being charged. The embodiment shown in FIGS. 7 to 9 is particularly effective.

(Fig. 10)
FIG. 10 is a conceptual diagram showing the temporal relationship between the reception of broadcast data and the output of content data, and content data is not always output at the timing of receiving broadcast data (in real time). An example is shown.

  It is assumed that the information terminal is a car navigation device and the automobile equipped with the car navigation device is an electric vehicle. In this case, the vehicle is charged when parked in the parking lot. The car's engine is stopped, but the receiving tuner is working. This receiving tuner includes the storage means shown in FIG. 6 and the like, and can store a large amount of content data.

In the embodiment shown in FIG. 10, there are at least two radio towers, one radio tower broadcasts content A for area α, and the other radio tower broadcasts content B for area β. Suppose you are.
For example, it is assumed that the place where the car is parked is a place where the content A for the area α can be received but the content B for the area β cannot be received. At the time of parking, the content A for the area α is received and the content A is stored in the storage means. But no output. This is because the car engine is not running and no people are on board.

  Suppose that time has passed and this car has left the parking lot. It is assumed that the content B for area β can be received. Then, the reception tuner accumulates the content B in the storage means. It is assumed that the driving of the car is continued and the car enters the area β where the content B is to be output soon. Then, control data indicating that the control means should output the content B is transmitted to the output means, and the content B is output.

Further, if the driving is continued and the vehicle comes out from the area β where the content B should be output, the control means transmits control data for stopping the output of the content B, and the output from the output means stops.
Further, it is assumed that the driving is continued and the car enters the area α where the content A is to be output. Then, the control means transmits control data to the effect that the content A should be output to the output means, and the content A stored in advance in the storage means is output from the output means.

(Fig. 11)
FIG. 11 shows what kind of output is made as content data on the liquid crystal screen of a smartphone as an information terminal.
“Daily Seafood Lunch” at “Takae Specialty Store ABC” is recommended as “Recommended Trip Spot”, and if you order “Daily Seafood Lunch” at “Tsubaki Specialty Store ABC” based on this information, 500 points will be awarded Is displayed.

Furthermore, it is asked whether or not to receive the route guidance from the current position to “丼 丼 店 ABC” by the route guidance application.
If the “Yes” button displayed on the screen is touched, the route guidance application is activated, and the route guidance application guides the route to “Kashiwa specialty store ABC” by the smartphone. As the display device, products that can be displayed in the format as shown in FIG.

If the reception tuner described above and the information terminal connected to the reception tuner are used, the content data is output only to the person existing at that time in the area specified by the distribution area data.
Moreover, since only the content data relevant to the whereabouts is output for the user using the information terminal, there is an advantage that information selection can be received automatically.

As a system that effectively uses the band used for analog broadcasting in accordance with the transition to terrestrial digital broadcasting, the embodiment described above is suitable for any of broadcasters, service providers in each region, and users carrying information terminals. Even it works beneficially.
Further, it is useful not only for service providers having stores and facilities in each region, but also for businesses that provide car sharing and rental cars as a system that encourages users to drive and motivate driving.

  The present invention realizes a broadcasting service business in radio broadcasting, a manufacturing industry of information terminals that can receive and utilize radio broadcasting, a rental business of information terminals, a service industry that manages and manages car sharing or rental cars, and car sharing or rental cars. The present invention has applicability in the information and communication service industry that provides support, the software industry that creates computer software for car sharing or rental car operation, the card credit industry, and the like.
