  By the way, broadcasts performed for wide areas such as general-purpose television broadcasts and radio broadcasts such as wide-area broadcasts and prefectural broadcasts (hereinafter referred to as general broadcasts) have a very wide audience. It must be an average and general one that everyone will receive. For this reason, the business model based on general broadcasting is like a mass advertisement distribution business.

  Recently, however, the hobbies, preferences, and necessary information of viewers are diversifying, and there is a limit to improving the audience rating only by providing average / general broadcast content that can be received by everyone. It ’s difficult to fully meet the needs of viewers.

  Here, there are usually regional differences in usefulness and needs for information (content) to be broadcast. For example, the usefulness of information such as tsunami and river flooding differs between people in a specific area such as a coastal area or around a river and people in another area. Also, for example, in places where people with common hobbies and preferences gather, such as Shibuya and Akihabara, needs for specific information such as fashion information, computer information, and animation information are very high.

  The present invention has been made paying attention to the fact that there is a regional difference in the usefulness and needs for such information, and enables the provision of broadcast content specialized for each specific area, and allows viewers in the region to It is an object of the present invention to provide a broadcasting method capable of providing broadcast contents that meet needs and usefulness.

  The main invention of the present invention for achieving the above object is a broadcasting method, in which a broadcasting radio wave transmission facility having a broadcasting area as a broadcasting area is provided in a certain area set by dividing the area. The broadcast content for the specific area is broadcast.

  In this way, the needs and usefulness of viewers existing in a specific area by broadcasting the broadcast content for the specific area targeted for the specific area set by dividing the area, that is, the specific area. Broadcast content suitable for

  Here, the specific area is, for example, an area set by dividing an area into regular hexagons. By making the specific area a regular hexagon, it is possible to minimize the interference of broadcast radio waves between adjacent transmission facilities when a transmission facility is provided in the center of the specific area, and efficiently allocate the frequency of the broadcast radio wave It becomes possible.

  An insensitive area of general broadcasting such as wide-area broadcasting or prefectural broadcasting may be set as the specific area. In the dead area, the broadcast radio wave of the general broadcast does not reach, so the frequency of the broadcast radio wave of the area portal broadcast in the specific area can be set to the same frequency as the general broadcast, and the limited frequency (channel) is used effectively It becomes possible to do.

  The transmission equipment can be mounted on a vehicle or the like to be mobile. Thereby, for example, it becomes possible to provide broadcast content flexibly to a specific area where there is a need for a limited time.

  As broadcast radio waves, broadcast radio waves of one-segment broadcasting or digital radio broadcasting can be used. The broadcast content is generated based on information provided by at least one of a disaster prevention related immediate information collection system, an ITS related immediate information collection system, and a normal service immediate information system, for example.

  Broadcast content is also a content collection / storage function for collecting content, a content processing / verification / storage function for content production processing and receiver verification, and a content transmission / distribution for sending and distributing broadcast content to a transmission facility. The content processing / verification / accumulation function and the content transmission / distribution function that are generated by a function and that function generically regardless of the type of content provided by the content collection / accumulation function are used.

  As a result, it is possible to quickly and easily provide broadcast content that meets the needs of viewers with a short life cycle through portal area broadcasting.

  According to the present invention, broadcast content specialized for each specific area can be provided, and broadcast content that meets the needs of viewers in the area can be provided.

  Hereinafter, one embodiment of the present invention will be described in detail.

= Area portal broadcasting =
The broadcasting method of the present invention (hereinafter referred to as “area portal broadcasting”) differs from broadcasting performed for a wide area such as wide area broadcasting or prefectural area broadcasting (hereinafter referred to as general broadcasting), and a plurality of areas such as a several km area are included. Broadcast radio wave transmission facilities are provided for each specific area that is divided into small areas, and broadcast radio waves with information specific to the specific area where the transmission facilities are installed are transmitted from the transmission facilities. Broadcasting method.

  As the broadcast radio wave of the area portal broadcast of the present invention, for example, the broadcast radio wave of a one-segment broadcast or the broadcast radio wave of a digital radio broadcast can be used. The area portal broadcast receiving terminal is, for example, an information terminal such as a mobile phone, a PDA (Personal Digital Assistance), or a notebook personal computer capable of receiving one-segment broadcasting.

  FIG. 1 shows a setting example of the specific area 10 that is a broadcast area in the area portal broadcast. In this example, the specific area is set in units of areas obtained by dividing Tokyo and Kanagawa prefectures and their surrounding areas into regular hexagonal shapes. At the center of each specific area, there is a broadcasting radio wave transmission facility in which the antenna height and transmission output are set so as to cover the specific area. By setting the specific area to a regular hexagon, it is possible to minimize the interference of broadcast radio waves between adjacent transmission facilities when the transmission facility is provided in the center of the specific area, and the frequency of the broadcast radio waves is efficient. It becomes possible to allocate well.

  As shown in FIG. 1, there is a gap between adjacent specific areas (regular hexagons), but this gap interferes with broadcast waves of area portal broadcasts transmitted from adjacent transmission equipment, This is a broadcast radio insensitive area where any area portal broadcast cannot be received.

  The area portal broadcast transmission facilities include a permanent transmission facility 11 and a mobile transmission facility 12 that can be moved to an arbitrary location by being mounted on the vehicle or the like. For example, a permanent transmission facility 11 is provided in a place where people gather constantly (hereinafter referred to as a residence base) such as a station square in a main station or an office district. On the other hand, a mobile transmission facility 12 is provided at a place where broadcasting is performed for a limited time. For example, the mobile transmission facility 12 is provided in a specific area where there is a high need for such information when providing disaster information or disaster information in a tsunami or river flooding. In addition, the mobile transmission facility 12 is also provided when performing area portal broadcasting for visitors at a limited time event venue or the like. In this way, by using the mobile transmission facility 12, for example, it is possible to provide broadcast content on an ad hoc basis to a specific area where there is a need for a limited time.

  In the example shown in FIG. 1, a permanent transmission facility 11 is provided in each specific area of the Shinjuku area, the Akihabara building, the Yokohama station area, and the Minato Mirai 21 area. In addition, mobile transmission facilities 12 are provided in three specific areas of the Odaiba event venue, the Yokohama Hakkeijima event venue, and the Sagami River upstream area.

<Use of insensitive area>
A broadcast that is performed over a wide area, such as a general broadcast, usually has an insensitive area for broadcast radio waves. For example, as shown in FIG. 2, most of the buildings, concourses, and underground malls around major stations in the city center are insensitive areas 20 for broadcast radio waves. Further, the dead area 20 such as the inside of a high-rise building also exists in a three-dimensional direction. Such a dead area can be used as the specific area 10 in the area portal broadcast. Then, by performing area portal broadcast with the insensitive area 20 as the specific area 10, the area portal broadcast becomes an effective broadcast medium for interpolating the general broadcast.

  Here, in the insensitive area 20, the broadcast radio wave of the general broadcast does not reach. Therefore, when the insensitive area 20 is set to the specific area 10, the frequency of the broadcast radio wave of the area portal broadcast in the specific area 10 is the same as that of the general broadcast. The frequency can be set, and a limited frequency (channel) can be used effectively.

  In addition, when using the same frequency as the frequency of the general broadcast in this way, it is necessary to appropriately set an area where the broadcast wave of the general broadcast and the broadcast wave of the area portal broadcast interfere. This setting takes into account the conditions for receiving either one of the broadcast radio waves, that is, the difference (28 dB) in the electric field strength between the two digital broadcast radio waves, It is necessary to set a coexistence area (underlay, overlay). As shown in FIG. 3, when the area portal broadcast is implemented, the interference area 31 and the coexistence area 32 are, for example, the transmission output of the broadcast wave of the general broadcast and the adjustment of the ground height of the broadcast antenna 33, the broadcast of the area portal broadcast It is set appropriately by adjusting the transmission output of radio waves, the ground height of the broadcast antenna 34, the application of a canceller technology, and the like. By setting the specific area in this way, it is possible to coexist with general broadcasting and area portal broadcasting.

= Collection and distribution of broadcast content =
FIG. 4 shows an example of a mechanism for collecting and distributing broadcast contents in area portal broadcasting. Broadcast content includes disaster prevention-related immediate information collection system 411, which is a system that collects real-time information on disaster prevention, ITS-related immediate information collection system 412, which is a system that collects information collected by ITS (Intelligent Transport Systems), Collected and stored by various content collection / storage functions 410 such as a normal service immediate information collection system 413, which is a system for collecting broadcast content of area portal broadcasting. The content collection / accumulation function 410 is a TVCML (Television Common extensible Markup Language) format that collects information collected by the disaster prevention-related immediate information collection system 411, the ITS-related immediate information collection system 412, the peacetime service immediate information collection system 413, and the like. Is stored in a computer (hereinafter referred to as an immediate information server 421).

  Next, the content production processing system 422 in the content processing / verification / accumulation function 420 uses the metadata (location information, etc.) referred to during distribution to a specific area based on the information stored in the immediate information server 421. ), Map data used for disaster prevention information, disaster information, traffic information distribution, etc., and data required for portal area broadcasts such as stored data (super distribution format) used in peacetime services. These data are verified by the receiver verification system 423 as to whether or not they are broadcast contents that can be received by the receiving terminal, and then transmitted to a computer (hereinafter referred to as a data broadcast content server 424) on a BML (Broadcast Markup Language). Stored in format. The BML format data stored in the data broadcast content server 424 is transmitted / distributed to the transmission facilities 11 and 12 provided in the specific area by the broadcast transmission facility 431.

  4, the content processing / verification / storage function 420 and the content transmission / distribution function 430 are constructed as a general-purpose system. Therefore, even when a new type of information is collected / stored by the content collection / storage function, the specifications of these systems do not change and can be used for general purposes. With such a mechanism, it is possible to provide broadcast content that meets the needs of viewers with a short life cycle by portal area broadcasting quickly and easily.

= Application example =
Next, some application examples of area portal broadcasting will be described. As shown in FIG. 5, according to area portal broadcasting, for example, provision of disaster prevention information / disaster information, provision of traffic information, provision of community-based information, etc. It is possible to provide specialized information. The following introduces various application examples of area portal broadcasting.

Automatically switches to content based on traffic information broadcast. For this reason, the sub screen 72 always displays traffic information corresponding to the current vehicle position that is useful for the vehicle.

  Note that the latest traffic conditions such as roads and bridges, traffic information such as traffic congestion information and traffic information provided by area portal broadcasting are information collected by the ITS-related immediate information collection system 412, for example. Further, this information is information collected by an optical beacon, DSRC (Dedicated Short Range Communication) or the like collected by a distributed signal device 92 provided on a distributed signal pole 91 as shown in FIG. The information is extremely immediate (position information, speed information, etc.).

<Providing community-based information (normal service)>
According to area portal broadcasting, it is possible to provide community-based information with high immediacy as a normal service. Also, for example, in places where people with a certain hobby thought (hereinafter referred to as individuals) gather, such as around Shibuya Station and Akihabara Station, information about fashion, information about computers, information about animation, etc. Can be provided as a normal service by area portal broadcasting. In addition, as information specific to a specific area, information that is useful only in a specific area, such as timed sales information held at stores in the specific area, or information on event venues, may be actively broadcast. it can.

  In other words, in general broadcasting that targets broadcasting in a wide area, viewers have a wide range of hobby thoughts, so it is unavoidable to provide average broadcasting content aimed at everyone. It is possible to broadcast information specialized in the broadcasting, and to actively provide broadcasting content that meets the needs of viewers. The broadcasting side can also expect high advertising effectiveness.

  On the other hand, by combining the area portal broadcasting and the communication service using the Internet or the like, it becomes possible to provide a highly immediate service specialized for the individual. In other words, the fusion of area portal broadcasting and communication services has created a new segment marketing value chain centered on content services for individuals, with the departure from mass business centering on 20th-century popular entertainment content. Will be. In addition, it is expected to create a highly profitable platform business by making it possible to realize an efficient service system through distribution services for the optimal specific areas, with the source of profit being the discovery of good content and individual segments .

  FIG. 10 shows an example of a platform business model using area portal broadcasting. As shown in the figure, as the content 91 of the community type using the area portal broadcasting, for example, international exchange (language, culture, etc.), local activity (town information, art museum, etc.), hobby exchange (Music, games, etc.) can be considered. Then, as a platform business model using area portal broadcasting based on these individual community type contents 91, an advertising business as a B2B type business (contract or success fee) for advertising and advertising these individual community type contents 92 is created. Further, a sales promotion / customer collection support business 93 is created as a B2B, B2C type business (revenue share).

  On the other hand, a business 94 for creating and managing a personal community performed via communication such as the Internet is created. In addition, a system construction business 95 is inevitably created as a B2B type business (contracting or joint business) for constructing a transmission system / reception system for area portal broadcasting, which is a foundation for realizing these business models.

  The advertising business 92 includes, for example, production and distribution of advertisements in one-segment broadcasting and digital radio broadcasting. The advertising business 92 is characterized by the formation of individual communities and measurement of effectiveness through integration with communication services performed via the Internet or the like. The content sales promotion / customer collection support business 93 includes, for example, sales promotion by a one-segment broadcasting program and customer collection support. In addition, large-capacity distribution services such as music, educational contents, electronic books, games, and the like by digital radio broadcasting can be considered. The content sales promotion / customer attraction support business 93 is characterized by mass storage using storage-type DRM technology (super distribution) and use of demand communication.

  Examples of the system construction business 95 include provision of technology for receiving terminals, construction of specific area (large-scale business / commercial / educational facilities, transportation systems, theme parks, event venues, area portal broadcasting services for tourist destinations). After the system related to area portal broadcasting is constructed, it is used as an exit for the advertising business 92, the content sales promotion / customer collection support business 93, etc., and these operation service businesses are established.
