[0010]

First Embodiment A broadcasting system according to the first preferred embodiment of the present invention will be described.

The optimum broadcasting system according to the present invention is a digital teletext system.

The digital teletext system comprises information providing means, broadcasting means and receiving means.

The information providing means is composed of at least one digital teletext transmission terminal 10 and the first communication means 20, and is operated by the information provider.

The broadcasting means is the digital teletext center 3.
0 and the second communication means 40.

The receiving means comprises a character radio 50 and a library system 60 and is operated by the user.

The digital teletext transmission terminal 10 (hereinafter, simply referred to as a transmission terminal) comprises a personal computer, a modem, and digital teletext providing software. The personal computer has a word processing function and is connected to a modem. The modem is a digital telecast center 30 (hereinafter simply referred to as a broadcast center) via the first communication means 20.
It is connected to the. The digital teletext distribution software is set on the personal computer and has an article flow mode and an article creation mode.

As the first communication means 20, conventional communication means, for example, digital communication such as personal computer communication or data communication can be adopted.

The transmission terminal 10 transmits the transmission data to the broadcasting center 30 via the modem and the first communication means 20.

The transmitted data is composed of selective factors and articles.

The selective factor is composed of, for example, a transmission time code, an information provider code, a genre code, an importance code and a keyword part.

The article is composed of, for example, a headline, an outline, and an article body (details, supplements, explanations), and is classified into any of a plurality of genres depending on its content.

The calling time code is the calling time (year. Month.
Day. It consists of 8 digits that indicate the hour.

The information provider code is composed of 8-digit alphanumeric characters and is preset for the information provider.

The genre code is composed of 8-digit alphanumeric characters and is preset for the genre.

One importance code is selected from five English letters A, B, C, D, and E depending on the importance of the article. For example, when the information provider is the media or government office, the importance code is selected as follows. A is selected when it is expected that most (80% or more) users of digital teletext systems will be interested in the article. When 60-80% of the users are interested, about half of the users, 30-40%, or less than 30%,
B, C, D and E are selected respectively.

The keyword part is composed of three or less keywords. Each keyword is a letter, number,
It consists of Kanji and Hiragana.

The headline, the outline, and the text of the article are made up of kanji, hiragana, alphanumeric characters, etc., and the length (number of characters) is not limited.

Next, the genre will be described. Genres are roughly classified into six fields: news, daily life information, public information, company information, and personal information. These six fields and their genres will be described next in sequence.

[0029] The news is a field in the form of "when, who (group) did what", and the date and time of transmission has an important factor. There are six genres classified as news: politics, economy, society, science, sports / entertainment, and celebrities.

Life information is a field related to knowledge used in life. Genres classified as living information are literary arts, cooking, travel, health, and medical care.

Public information is a field related to guidance from government offices and schools. The genres classified as public information are National Assembly pleadings, local administration, school guidance, and local disasters.

The company information is a field relating to advertisement and guidance from the company. The genres classified as corporate information are
New products, product information, bargains, theater / movie information, and entertainment business.

The personal information is a field related to a letter from an individual. The genres classified as personal information are sales, associates, correspondents, and local events.

Next, a method of creating transmission data will be described.

First, either the article flow mode or the creation mode is selected. When the article pouring mode is selected, while pouring a sentence into a personal computer, the sentence is found, the article is automatically divided into three parts, an outline and an article text, to create an article. If you select the creation mode, create an article using the word processing function of your computer. However,
The outline may be omitted. After the article is created in this manner, the transmission time code, the information provider code, the genre code, the importance code, and the keyword are input, and these are added to the article to create transmission data. However, the genre code may be omitted. After that, the transmission data is checked by the digital teletext providing software to see if it conforms to a predetermined format, and if it conforms, it is transmitted to the broadcasting center as described above.

Next, the information provider will be described.

Each information provider has a contract with the broadcasting center 30 in advance regarding the content of articles and the load of charges. The information providers include the media, government offices, schools, companies and individuals. Each will be described in order.

The media is, for example, a newspaper company, a magazine company, a publishing company, or their related organizations, and receives a fee from the broadcasting center 30 according to the provided articles.

The public offices are respective organizations such as the bulletin department of the public offices, for example, the Cabinet, the Diet, the government offices, the prefectural offices, the cities / towns / villages, and the charges are free or special charges.

The school is a school corporation, for example, a university, a high school, a junior high school, an elementary school, and the charge is free or a special charge.

The company is, for example, a maker, a department store, a trading company, a bank, an insurance company, or the like, and is an information provider who is expected to obtain a profit such as a commercial effect by providing articles. Therefore, the company pays the broadcasting center 30 according to the content (information) of the article.

The individual is an individual who has made a contract with the broadcasting center 30. The price depends on the content of the article.

Next, the broadcasting center 30 will be described.

The broadcasting center 30 is equipped with data receiving means (not shown). The data receiving means is, for example, a computer in which automatic genre determining software is set.

The broadcasting center 30 receives the transmission data transmitted from the transmission terminal 10, determines whether or not the transmission data conforms to a predetermined format, and receives and registers only the conforming transmission data. The time when the transmission data is registered automatically becomes the transmission time, and the transmission time code of the transmission data is changed accordingly. If the outline of the transmission data is omitted, the 400 characters from the beginning of the article body are automatically used as the outline. When the genre code is omitted, the genre code is automatically determined by the automatic genre determining software.

After that, the broadcasting center 30 broadcasts all the registered transmission data via the second communication means 40. The second communication means 40 is one that broadcasts by radio waves or high-speed communication such as ISDN, and a conventional communication means can be adopted.

Each transmitted data is broadcast only once,
One transmission data item is not broadcast many times. For example, transmission data having articles whose contents change with time, such as news, is broadcast only once each time.

The broadcasting center 30 automatically creates a list of registered transmission data for each information provider, and determines the charge burden according to the above-mentioned contract. Then, the information provider dictionary in which the name of the information provider and the information provider code are associated with each other is created.

Next, the character radio 50 will be described.

The character radio 50 is a display panel integrated type, and includes a computer (not shown), a RAM (not shown),
Display switch (not shown), display panel 51, NEXT
A page key 52, a NEXT article key 53, an article storage key 54, a table of contents key 55, an article information key 56 and a cursor key 57 are provided.

The personal teletext selection software, automatic layout software, and automatic table-of-contents display software are set in the computer.

A browse file and a save file are set in the RAM (random access storage device). The RAM has a recording capacity of 1 Mbyte and can store about one day's worth of characters in a newspaper.

The display panel 51 is a reflective LCD.
Hereinafter, displaying on the display panel 51 is simply referred to as displaying.

The character radio 50 receives the transmission data broadcast from the broadcasting center 30 for 24 hours, that is, always receives it. Then, the total score is set for the received transmission data. Then, the transmission data is sorted by the information collection menu. Only the transmission data sorted by the information collection menu is recorded in the browsing file, and the transmission data not sorted is not recorded.

The transmission data recorded in the browsing file is
When 24 hours have passed from the transmission time, the file is automatically deleted from the browsing file. Therefore, the transmission data recorded in the character radio 50 is automatically and steadily updated.

The transmission data having articles displayed even once is automatically deleted.

When the recording capacity of the RAM becomes full and the data cannot be recorded in the browsing file as it is, the transmission data recorded in the browsing file is erased in order of increasing total score and then recorded. However, if the total score of all the transmission data recorded in the RAM is higher than the total score of the transmission data recorded, the transmission data is not recorded and the transmission data recorded in the RAM is not deleted.

As described above, transmission data having old articles (transmission data after 24 hours have passed), transmission data having articles displayed even once, and articles having a low total score (articles of little interest to the user). The transmission data that has
It is automatically deleted. Therefore, the user can read the latest information article by the character radio 50.

The user can put a recording mark on a desired information provider code. Thereby, the transmission data having the information provider code is automatically transferred from the browsing file to the storage file and stored when the transmission data is recorded in the browsing file.

The transmission data saved in the save file is
It will not be erased even after 24 hours have passed since the time of transmission.

The user puts a recording mark on desired transmission data among the transmission data stored in the storage file.
For example, add a record mark to the article you want to scrap.

The character radio 50 is connected to the library system 60. When the character radio 50 is connected to the library system 60, the transmission data with a recording mark is automatically transferred and recorded in the recording device of the library system 60.

The total score is a sum of interest points (1 to 10 points) of the information provider code, genre code, keyword, and importance code of the transmission data, and is calculated by the score calculation table.

The interest points of the main information provider code, genre code, keyword, and importance code are registered in advance by the user.

Regarding other points of interest in the information provider code, genre code, keyword, and importance code,
First, a value obtained by multiplying the interest points of similar main information provider codes, genre codes, keywords, and importance codes by a predetermined rate is registered. After that, when the number of times these articles are read is small, the number of points of interest decreases at a predetermined rate. On the contrary, when the number of times of reading is large, the score is the same as the interest score of the similar items described above.

The point calculation table is created from the points of interest thus registered.

The information collection menu is automatically set as follows by the standard automation mode of the personal information selection software. First, the information collection menu is set so as to select the transmission data having the information provider code of the media such as a newspaper company or a magazine company and the importance code of any one of A, B, and C. After that, every time an article is displayed, read, or marked with a record mark by the user, the information collection menu is changed so that the transmission data having the genre code of the article is selected more by a predetermined ratio. It

The user is the information provider code of interest,
The genre code or keyword can be registered in the personal information selection software. Thereby, the information collection menu is set so that the transmission data having them is also sorted. For example, when the information provider code of the Asahi Shimbun is registered, the transmission data having the information provider code is also selected. Further, when the genre code of interest is registered, the transmission data having the genre code is also selected. As a result, articles of interest to the user are selected and recorded in the browse file.

The character radio 50 organizes the information providers, genres, and keywords of the recorded transmission data, and creates three tables of contents: a genre table of contents, an information provider table of contents, and a keyword table of contents. Then, each time the transmission data is recorded, the information provider, genre, and keyword are added to each table of contents. The table of contents is displayed horizontally by the automatic table-of-contents display software.

In the information provider table of contents, the names of the information providers are arranged in the order of Japanese syllabary, and the numbers of transmission data are made to correspond to each other. The name of the information provider can be looked up by the information provider dictionary from the information provider code of the transmission data. When the information provider code is not registered in the information provider dictionary, the information provider codes are arranged in numerical order and in alphabetical order from the end of the information provider name instead of the information provider name.

The genre table of contents is composed of a large table of contents, a small table of contents, and a heading table of contents, and has the following hierarchical structure.

The table of contents is a list of the above six fields. The small table of contents is created for each field and is an arrangement of genres. The heading table of contents is created for each genre, and the headings of the transmission data having the genre code of the genre are arranged in descending order of the total score, and the respective numbers are associated with each other.

The keyword table of contents is such that the keywords of the recorded transmission data are arranged in the order of Japanese syllabary and the number of transmission data having each keyword is made to correspond.

The display surface of the display panel 51 is 17 characters × 8.
It is preferable that the display surface is 320 × 200 dots capable of displaying 16-dot characters in a row (the number of characters is 136). Further, the size of the display surface is preferably 90 × 56 mm.

In the case of a character radio with a separate display panel, articles such as news can be displayed on a PC or TV screen at home or at work.

[0099] will be described broadcast system according to a second embodiment of the second embodiment the present invention.

This broadcasting system has the same structure as the broadcasting system of the first embodiment described above, and further has the structure described below.

The transmission data has not only characters but also voice information. The broadcasting center uses radio waves for broadcasting, such as FM.
Broadcast.

The receiving means includes a voice output means and a reception warning signal generating means, and receives the transmission data broadcast from the broadcasting center. The voice output means is, for example, a speaker, and outputs voice information of the received transmission data as voice.

The receiver may create an alarm condition by separately or combining the information provider code, genre code, importance code, keyword, etc., and set the alarm condition in the personal character information selection software. it can. In this case, when the receiving means receives the transmission data that meets the alarm condition, the transmission data is recorded in the browsing file by the personal teletext selection software, and the reception alarm signal generating means operates. The reception warning signal generating means is, for example, a lamp or a buzzer, and generates a warning signal such as lighting or a warning sound. further,
Along with that, articles of transmitted data are automatically displayed,
The receiving means may be configured to automatically output the voice information.

Next, a usage example of this broadcasting system will be described. Information providers are groups with multiple members,
Examples include schools, clubs, clubs and companies. These organizations operate the transmission terminals to send the transmission data to the broadcasting center. Then, the transmission data is broadcast by radio waves from the broadcasting center.

Members of each group, such as school students, club members, club members, company employees, etc.,
Each has its own receiving means. Then, for example, the alarm condition is set according to the organization to which the user belongs. Thereby, when the transmission data having the alarm condition, for example, the transmission data of the belonging organization is received, the alarm signal is generated.

Next, with reference to FIG. 7, a case where the information provider is a club will be described in more detail.

The club 71 sends, to the broadcasting center 73, contact information for the member 72, such as event information and meeting time, as transmission data. The transmission data sent to the broadcasting center 73 is broadcast by radio waves, and all members 7
1 is received by the receiving means 74.

The member 72 of the club 71 sets the information provider code of the club 71 as an alarm condition in the personal telecasting selection software of the receiving means 74 each owns. As a result, when the transmission data of the club 71 is broadcast and received by the receiving means 74, an alarm signal is generated. This warning signal can call the attention of the member 72. Therefore, it is possible to prevent the member 72 from missing the transmission data of the club 71, and reliably transmit the contact information from the club 71 to the member 72.

In this way, by the broadcasting system, the club 71 contacts all the members 72 at one time,
Moreover, each member 72 can be surely contacted.

Alternatively, each member may send the transmission data to the broadcasting center and contact all other members. In this case, the members can contact each other.

Other groups of the club can be contacted in the same manner.

As described above, the present invention is suitable for contacting an organization having a large number of members. Especially 200 people
It is ideal for contacting groups with 300 members.

The alarm condition is not limited to the above. For example, the alarm condition can be created by combining the information provider code and the importance code. In this case, for example, it is possible to use the importance level of a contact item that requires urgent attention among the contact items from the club as the importance code of the alarm condition and generate the alarm signal only during the emergency contact.

The present invention is not limited to the first and second embodiments described above.

For example, the present invention can be applied not only to the digital teletext broadcasting system but also to other broadcasting systems, for example, a broadcasting system for broadcasting transmission data composed of not only characters but also voices and images. Also in that case, as in the case of the digital teletext system, a selective factor is provided to select the transmission data.

[0116]

INDUSTRIAL APPLICABILITY The present invention provides a broadcasting means for broadcasting a plurality of transmission data having a selective factor and an article, a broadcast transmission data being received, and a transmission having a desired selective factor from the transmission data. Since the receiving means for selecting and recording the data is provided, the receiving means can receive a large amount of transmission data and automatically select and record desired transmission data from them. Therefore, for example, an editor of a newspaper or a magazine broadcasts the transmission data by the broadcasting means, and the user can receive only the desired transmission data by the receiving means. In this case, the editor can deliver all the articles to the user without selecting the articles to be posted or the layout of the articles,
Moreover, the user can record only articles of interest and not articles of no interest. Furthermore, it is possible to pay only for articles that are recorded and not for articles that are not recorded. Thereby, the above-mentioned problem is solved.
