Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data distribution system for distributing desired information (data) to a terminal device used outdoors.

[0002]

2. Description of the Related Art Conventionally, as a method for a user to obtain necessary information, as shown in FIG. 1, an information terminal such as a personal computer or a mobile phone equipped with a reproduction display device 1, a storage device 2 and a control device 3. There is a method in which various websites 6 on the Internet 5 are accessed by using the Internet 4, and information provided by the website 6 is searched and downloaded to the information terminal 4 via the Internet 5.

[0003] In a tourist resort or a museum, guidance voice for explanation is carried on a weak radio wave at a specific place and transmitted at all times, and when a user comes to that place, it is handed to the user in advance when he / she enters. There was also a method in which the weak radio wave was received by a dedicated receiver, and the guidance voice could be heard.

[0004]

However, with the above-mentioned method of downloading information via the Internet, it is difficult to download a large-scale file such as moving image information outdoors at high speed, and it is difficult to search for information. There was a problem that it took time. In addition, in information transmission using weak radio waves, there is a problem that the receivable place is limited.

It is an object of the present invention to provide a data distribution system capable of easily searching a large-scale file such as moving picture information outdoors, and downloading and reproducing at high speed.

Further, the object of the present invention is not only for the user to specify and retrieve information representing some attribute of the desired distribution information, but also for information on a geographical area within a predetermined range from the position of the user. Is to provide a data distribution system capable of automatically and continuously searching.

[0007]

According to the present invention, in order to achieve the above object, a wireless relay device, a transmitting device for transmitting distribution information to the wireless relay device, and receiving distribution information relayed by the wireless relay device. A data distribution system including a receiving device, wherein the transmitting device includes moving images, still images, audio,
Storage means for storing a plurality of distribution information including at least one attribute information indicating some attribute of the information body together with the information body composed of characters and the title thereof, and the plurality of distribution information stored in the storage means are repeatedly used as a wireless relay device. The receiving device includes a transmitting unit for transmitting, the receiving device collates the attribute information of the received distribution information with the search information input by the user, and stores the title of the distribution information for which the collation result matches, and the stored title. Of the above, the distribution information including the title designated by the user is received from the wireless relay device,
And means for storing and reproducing.

According to the above configuration, since the distribution information is distributed by relaying the wireless relay device, it can be downloaded at high speed even outdoors, and the search is performed at high speed by the attribute information added to the information body. Is possible. Further, since only the title is temporarily stored in the search result and then the information body of the desired distribution information is stored, the capacity of the storage device of the receiving device can be reduced.

At this time, the distribution information including the attribute information which is the geographical position information is used, and the receiving device is
Position acquisition means for acquiring its own geographical position information, attribute information of the received distribution information, information indicating a geographical range input by the user, and a geographical area specified by the acquired position information. And a means for storing the title of the distribution information having the attribute information included in the geographical area are provided, the information on the geographical area within a predetermined range from the user's position is automatically obtained. Moreover, it becomes possible to continuously search, and for example, while driving in a car, information on surrounding areas can be received and reproduced one after another.

In the example of the distribution information shown in FIG. 4, the attribute 1 is the information type such as a tourist attraction guide and the attribute 2 is the location, and the search information is also input with the information type and the name of the municipality. All inputs are selected from the pull-down menu. For the search, matching processing is performed with the attributes 1 and 2 of the distribution information using the inputs 1 and 2 shown in FIG.

FIG. 11 shows a reproduction display device 33 of the receiving terminal 30.
Another example of the search information input screen displayed in, here G
The input example of the geographical area in the case of including the PS device 35 is shown. Input 2 specifies to use the position information from the GPS device 35, and input 3 specifies a geographical range centered on the position of the receiving terminal 30. Based on the input 3 and the value of the position memory 342 inside the control device, it is determined whether or not the position information of the attribute 3 of the distribution information falls within the designated geographical area.

FIG. 12 shows an example of a display screen on the reproduction display device of the title of the distribution information that matches the search information shown in FIG. 10 or 11. When a desired title is designated (by clicking or the like) from among the plurality of titles, as described above, when the control device 34 of the receiving terminal 30 receives the distribution information having the corresponding title, this is stored in the storage device 32. The information is stored and reproduced and displayed on the reproduction display device 33.

When the information type, the attribute, etc. are added, it is necessary to change the items displayed on the search input screen or the pull-down menu in the receiving terminal, but this change is also made from the transmitting device via the wireless relay device to the receiving terminal. It can be realized by sending a program or data to.

[0034]

As described above, according to the present invention,
It becomes possible to search and display information about the surrounding area at high speed outdoors. If this kind of information is stored in advance in the information of a personal computer or the like, the amount of memory becomes huge and it is difficult to realize. Compared with the method of searching and reading what is stored in a static memory such as a CD-ROM, the latest information can be obtained.

Also, by combining with GPS, it is possible to receive and reproduce regional information one after another while traveling in a car, for example. It is possible to automatically execute tourist information. Also, it is possible to easily find a nearby restaurant or fast food restaurant while traveling.

It is also possible to include a commercial in the information content and utilize it for a business in which income is obtained from the sponsor. Alternatively, tourist information can be utilized in a business of receiving an information transmission fee from the local government and transmitting it.

A business model is also possible in which the distribution information is subjected to an encryption process such as scrambling, the decryption key is distributed only to paying members, and the decryption key can be decrypted at the receiving terminal.

Further, a mobile phone function such as i-mode is added to the receiving terminal, and information indicating that the distribution information is reproduced by transmitting the i-mode for each reproduction display of the distribution information is sent to the distribution side and used for each information use. A business model of charging users is also possible.
