DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to information distribution used for information distribution between computers of a large number of clients and servers, and between a center such as a radio base station and a mobile radio telephone such as a portable telephone. The present invention relates to a method, an information distribution system, a receiving terminal device, and the like.

[0002]

2. Description of the Related Art In recent years, information transmitted from an information transmitting side to a large number of information receiving sides has been automatically distributed, or information that unilaterally transmits various and large amounts of information has been desired. Various distribution services are provided. For example, there are various information distribution services transmitted from a server to a specific client group that wants to distribute specific information using the Internet or the like. Also, in the mobile phone service field, an information distribution service for unilateral transmission from a base station to all mobile phones in an area is performed (for example, an area-based information distribution service “Station” of J-Phone West Japan Co., Ltd.).

In the information distribution service for distributing the specific information described above, the information receiving side exchanges the identification information (for example, an IP address or a mobile phone) for itself in exchange for receiving the distribution service for the specific information desired by the information receiving side. Personal information (name, gender, age, date of birth, occupation, address, contact information, hobbies, desired information type, etc.) must be registered with the information sending side There is. On the other hand, the information sending side collects and obtains a large number of personal information from the information receiving side, and in exchange for being able to enclose customers, the desired type for each client is selected from a large amount and variously supplied and obtained information. Therefore, it is necessary to perform an operation of associating individual information with a client group to which the information is to be transmitted, and then distributing specific information to the specific client group.

[0004] Further, in the information distribution service for unilaterally distributing the above unspecified and large amount of information, news, leisure information, event information, shop information, weather information, etc. are provided to all subscribed cellular phones or all clients in a certain area. All kinds of information such as forecasts are distributed uniformly and unilaterally, and each mobile phone or each client automatically receives all the information and stores it in a memory.

[0005]

However, when receiving the above-mentioned specific information, the information receiving side wants to receive the specific information, but the personal information of oneself is not protected by privacy protection or leakage of personal information. There is a situation that they do not want to register on the information sending side because they are worried, that is, they do not want to go outside. In addition, when various information is unilaterally received, there is a disadvantage that the memory having a limited storage capacity is occupied by the automatic accumulation of unnecessary information that is not desired to be distributed on the information receiving side.

On the other hand, the information transmitting side targets a client group having a specific attribute (for example, only men, only certain age groups, only certain occupational workers, only housewives, or only sports enthusiasts, etc.) to a specific type of client. There is a request to distribute information. In particular, if the information source has a business of receiving and delivering a distribution request with specification of certain information and an attribute of a target client to which the information is to be distributed, realization of the above request is not a matter of information distribution. Needed for efficiency. In this case, collecting and accumulating personal information of each client is indispensable for extracting a target client having the specific attribute from many clients.

[0007] The present invention has been made in view of such circumstances, and an object of the present invention is to distribute specific information only from an information transmitting side to an information receiving side having a specific attribute. An information distribution method capable of distributing only to the information receiving side having the specific attribute even if performing unilateral distribution at random without performing processing such as collection / acquisition of personal information and extraction of the information receiving side having the specific attribute, and An object of the present invention is to provide an information distribution system. Another object of the present invention is to provide a receiving terminal device capable of receiving only specific information that matches its own attribute without sending personal information such as its own attribute to the outside on the information receiving side.

[0008]

In order to achieve the above object, according to the first aspect of the present invention, in an information distribution apparatus, in an information distribution apparatus, reception information intended to distribute the main content is transmitted in addition to the main content as transmission information. A target group of the terminal device is constructed by including target information specified by attribute information selected and designated from various attribute items, and this transmission information is broadcast to all predetermined receiving terminal devices including the target group. On the other hand, in each of the receiving terminal devices, its own personal attribute information corresponding to the attribute item is input and set in advance and stored, and when the transmission information is received, the target information and the personal attribute are received. The transmission information is compared with the information, and the transmission information is stored and held only when both match.

According to the first aspect of the present invention, even if the information distribution apparatus broadcasts the transmission information to all the predetermined receiving terminal apparatuses, each of the receiving terminal apparatuses transmits the target information (for example, a certain age range) in the transmission information. Only when a man, a certain occupation, a certain sports enthusiast, etc.) and his / her personal attribute information (eg, age, gender, occupation, hobby, etc.) match, the transmission information is accepted and stored. Will be done. For this reason, each receiving terminal device is prevented from storing and holding unnecessary transmission information, so that only the transmission information necessary for itself can be obtained. On the other hand,
In the information distribution apparatus, the target information (group of target receiving terminal devices) intended for distribution is added to the main content for distribution by adding the target information specified by the attribute information to the transmission content. The broadcast can be transmitted to the terminal device. Thereby, processing such as collection of personal information for narrowing down the receiving terminal devices of the target group and extraction / setting (for example, extraction / setting of an IP address) for specifying the target group based on the collected personal information. Can be omitted, and distribution efficiency can be improved.

Here, when the target information and the personal attribute information do not match each other, processing for deleting temporarily stored transmission information or rejecting reception of main content following the target information (rejection of incoming call). Should be performed. Further, the above "predetermined all receiving terminal devices"
For example, all client computers as receiving terminal devices that can be connected to a certain server via a network, or all subscriber telephones as receiving terminal devices in a certain area, are mentioned. The subscriber telephone is preferably applied to a mobile telephone which is a mobile communication device, but is also applicable to a fixed telephone.

A transmission information generating unit 22 for generating transmission information for broadcast transmission, and a transmission unit 23 for broadcasting the generated transmission information. Note that the number of server computers 2 as such an information distribution device is not limited to one,
There may be more.

The transmission information generating means 22 generates transmission information by adding target information to main contents which are contents to be distributed. The main content includes information to be distributed, such as economic information such as stock prices, new technology development information, shopping information, event information, or questionnaire request information. Such main contents may be those that are planned and input by the company that manages the server computer 2 itself,
Alternatively, the data may be transmitted through the network 3 and received by the server computer 2 in response to a request from another company.

The target information is configured by attribute information set according to a target group (client computer group) intended to distribute the main content. For example, in addition to “sex”, “age”, “occupation”, “region”, “hobby”, etc., one or two or more combinations of various attribute items such as “information type and its genre” of the main content can be selected. Select and set the content according to the target group you want to distribute for the selected attribute item. Then, the set attribute information is set as target information. If the main content is, for example, so-called brand sale information such as handbags, “sex”, “age group”, and “information type and genre” are selected as attribute items, and “female” and “18 to 50” are respectively selected. , "Shopping information / clothing" and set the target information.

The transmitting means 23 is a client server 4a which has previously obtained identification information such as an IP address.
The transmission information generated by the transmission information generation means 22 is uniformly broadcast to all of 4b, 4c, 4d,.

First, it is determined whether or not the personal attribute information has been set, and if not set, a display requesting an input setting is output to the display means 45 (NO in step S1, step S2). For example, "Please input and set personal attribute information."

In the input setting of the personal attribute information, various attribute items are displayed on the display means 45, and the user inputs and sets his / her personal attribute using the input means 44 for each attribute item. Become. The attribute items are set so as to be unified with the attribute items when the target information is set in the server computer 2 or to include at least the attribute information when the target information is set. Then, the user displays on the display means 45, for example, “sex”, “birth date”, “occupation”, “region”, “hobbies”, “interesting sports”, “information types and genres desired to be obtained”. When the user sets his / her personal information for various attribute items such as, for example, the personal attribute information is stored and held in the personal attribute storage unit 431 (step S3).
YES, step S4).

Thus, for example, in the client computer 4a, the gender is "male", the date of birth is "1972.05.26", the occupation is "doctor", the area is "Hyogo", the hobby is "movie watching", and the sports are “Skiing” and “Medical,
Personal attribute information such as “new drug / medical accident” and “economy, stock price” is stored and held. Alternatively, for example, in the client computer 4b, obtain “sex” as the gender, “1968.05.28” as the date of birth, “housewife” as the occupation, “Osaka” as the region, “music appreciation” as a hobby, and “none” as a sport. Personal attribute information is stored and held as a desired information type or genre, such as "shopping, clothing / clothing". At this time, priority may be set for the attribute items.

On the other hand, if the personal attribute information has already been set in the judgment in the step S1, or if the step S4
Then, it is determined whether or not there is transmission information from the server computer 2, that is, whether or not there is reception (step S5). If received, first, the target information included in the transmission information is extracted, and it is determined whether the target information matches the personal attribute information in the personal attribute storage unit 431 (YE in step S5).
S, step S6). This match determination is made based on whether or not the content of the attribute item set in the target information matches the content of the corresponding attribute item in the personal attribute information. At this time, even if the keywords do not match completely, they are determined to match if the keywords match. When the priority order is set for the attribute items of the personal attribute information, if the contents of the first-order attribute items match, it is determined that they match even if the contents of the other attribute items do not match. You may do so. Furthermore, the match determination for the “age group” included in the target information is based on the comparison between the data set in the “date of birth” of the personal attribute information and the built-in electronic clock, and the current age determined by the above “age” It may be performed depending on whether or not it is included in the content of the “layer”.

If it is determined in step S5 that they match, all of the transmission information is stored and stored in the storage unit 43 (YES in step S6, step S7). Erase (Step S
No in step 6, step S8).

Thereafter, a corresponding process (for example, a display process) is executed based on the processing command included in the stored reception information or the processing command input by the input means 44. At this time, when it is determined in step S6 that there is a match, only the fact that there is automatic reception information may be displayed on the display means 45 to notify the user. Further, the reception information stored by the automatic reception in the above step S7 may be automatically deleted after a lapse of a time set in the control means 41 in advance, or a time limit included in the transmission information from the server computer 2 may be used.

A plurality of the above-mentioned large genre information is selected and their priorities are set, or a plurality of the above-mentioned small genre information is selected (for example, “soccer” and “baseball” are selected) and the priority in the small genre is set. Settings.

Next, in the channel order switching section 121, a channel group (first-order channel) that matches the first-rank genre information of the above-mentioned priority from the current program information and channel information separated from the transport stream. ) Are extracted and arranged, and then a process of extracting and arranging a channel group (second-order channel group) matching the second-rank genre information is sequentially performed up to the last rank.

When the user operates the forward switching switch of the channel of the operation unit 15 or the remote controller 16, the program corresponding to the first-ranked channel group is switched regardless of the previously viewed channel. The information is displayed on the display unit 13 in order for each operation. If the above-mentioned switch operation is performed even when all of the first-order channel groups are displayed, the second-order channel groups are displayed in the same manner as described above.

When the user is a plurality of co-owners, such as when the television receiver 11 is used by a family, the genre information is input and set for each co-owner, and stored in the memory 122. What is necessary is just to make it memorize | store and hold individually in the storage area allocated for every sharer. Then, first, identification information indicating which sharer is currently viewed is displayed, and then a first-ranked channel group extracted and arranged based on the input genre information of the sharer is displayed. What should I do? Again,
Priority information for each time zone for each sharer's viewing time zone is input and set in advance, and the genre information of the specific sharer having the first priority in this time zone is used for the set time zone. You may. In addition, when a time zone for viewing by each sharer is assumed in advance, the switching may be automatically performed without the input setting of the time-based priority information.

According to the above television receiver 11,
Even if there are multi-channel broadcast programs such as 100 channels, the user can easily and quickly view his / her favorite broadcast programs without scanning all the channels, which is a great convenience. That is, the performance is improved.

The above technical ideas are summarized as follows. That is, in the receiving terminal device (television receiver 11), the genre information of the broadcast program that the user wants to view is input and set in advance, stored and held, and based on the program information and channel information included in the received digital broadcast wave. This is a program selection processing method for extracting a channel group that matches the genre information, and displaying a broadcast program corresponding to the extracted channel group with priority when a forward switching operation of the channel is performed.

Further, a display means (display section 13), an input means (operation section 15 or remote controller 16), and a storage means (memory 122) which stores and holds desired genre information inputted and set by the input means. ), Separating means (demultiplexer) for separating program information and channel information included in the received digital broadcast wave, and channel sequential switching means (channel order) for switching the channel order based on the separated program information and channel information. Switching unit 121), the channel order switching unit extracts a channel group that matches the stored genre information based on the current program information and channel information separated by the separation unit, and outputs the channel group from the input unit. When the channel switching operation is performed, the channel corresponding to the extracted channel group is released. The program is configured to be displayed on the display means is a television receiver.
