Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a receiving apparatus for presenting information transmitted by digital broadcasting, the Internet, or the like in accordance with a viewer's preference attribute.

[0002]

2. Description of the Related Art Recently, digital broadcasting has begun, and a large number of programs are provided using multiple channels. Multi-channel in digital broadcasting is realized by multiplexing a plurality of channels in one band. This multiplexing is performed by MPEG2 (Moving Picture Exp Exposure).
A technology called transport stream in the rts Group 2) standard is used. In particular,
It is described in the ISO / IEC standard 13818-1 (MPEG2 system) standard. With this MPEG2 transport stream, it is easy to distribute not only video and audio but also large-capacity data. For digital broadcasting, data broadcasting using this data distribution is being put to practical use. In data broadcasting, a viewer can select and view desired information by operating a remote controller or the like from a large amount of data transmitted by broadcasting.

[0003] One of the major features of broadcasting is that information is distributed to a large number of receiving terminals in a broadcast manner. Many research activities on information filtering technology for receiving or presenting only information suitable for attributes have been performed. In this information filtering, items such as viewer preferences and attributes and actual values are centrally held as filtering information at a receiving terminal, and transmitted information includes viewer preferences and the like of the viewer who wants to show the information. A filtering pattern describing attribute items and values is provided. Since the number of preference attribute items that the receiving terminal can hold is finite, the content of the preference attribute used for filtering is fixed on the sending side.

[0004] When the receiving terminal receives the information,
By selecting the information by comparing the assigned filtering pattern with the filtering information held by the terminal, information reception and information presentation suitable for the tastes and attributes of the viewer are realized.

[0005]

In the case of a content distribution service, there are various types of preferences and attributes of target audiences who want to show their content for each content provider that provides the content. Further, such information is very important as marketing information of each content provider, and is information that is not desired to be known to other companies.

However, in the case where the preference attribute items used by the receiving terminal and the input values of the viewers are centrally managed as in the conventional information filtering technology, the contents of the preference attribute items provided by the company and the viewer input values are provided. (For example, the contents of the questionnaire and the result of the viewer's response) may be referred to or rewritten from the content of another company.

[0007] Further, there are many contents whose contents are temporary or for a limited time, and the preferences and attributes of the required target audience are often temporary or for a limited time. However, in the conventional technique, since addition, change, and deletion cannot be performed, the preference attribute item must be registered in advance, and there is no use after a period, which is wasteful.

The present invention has been made in view of the above-mentioned conventional problems, and a first object of the present invention is to provide an information presenting apparatus for presenting information sent by digital broadcasting, the Internet, or the like in accordance with a viewer's preference attribute. To provide.

[0009] A second object of the present invention is to provide information which can efficiently utilize a storage area with a small number of receiving terminals and can provide temporary or limited-time content even in accordance with a viewer's preference attribute. It is to provide a presentation device.

[0010]

In order to solve the above-mentioned problems, an information presenting apparatus of the present invention comprises: a received information storing unit for storing received information; a presented information storing unit for storing received information presented information; A filtering information holding unit for holding at least one or more freely referable and editable filtering information and filtering information for limiting a referable and editable business entity; A filtering information control unit that performs editing and a presentation information control unit that controls presentation information according to the content of the filtering information are provided, and the filtering information has at least one or more fields, version values, and items.

On the other hand, according to the information description method of the present invention, the received information acquires only permitted filtering information from the identification information of the filtering information, and controls the presentation information according to the content of the filtering information. Is controlled to update the contents of

With this configuration, a plurality of content providers can manage, refer to, and edit their own filtering information, have filtering information that is more closely related to the content of their content, and have more viewer preference. Content presentation suitable for attributes can be realized. Since the filtering information unique to each content provider can restrict reference and editing from the content of another provider, it is possible to prevent leakage of the filtering information as important marketing information.

[0013] In addition, by storing and reusing a plurality of pieces of temporary or time-limited filtering information, a storage area with a small number of receiving terminals can be efficiently used, and temporary or time-limited contents can be used by viewers. It is possible to make a presentation that matches the taste attribute.

[0014] Further, by providing the expiration date to the filtering information, it becomes possible for the advertisement provider to use the filtering information for a limited time.

[0015]

The reproduction unit 107 reads the interactive data stored in the reception information storage unit 102 according to the input command received by the input unit 106, outputs the presentation information to the presentation information holding unit 103, and outputs the presentation control information to the presentation information control unit. The control unit 105 requests the presentation information control unit 105 to interpret the presentation control information and control the presentation information. Upon receiving the interpretation of the presentation control information and the notification of the completion of the presentation information control from the presentation information control unit 105, the reproduction unit 107 issues a presentation information display request to the display unit 108.

The presentation information holding unit 103 stores the presentation information output from the reproduction unit 107. The display unit 108 displays the presentation information held by the presentation information holding unit 103 in accordance with the display request from the reproduction unit 107. The display unit 108 is generally realized by a TV monitor, a display, or the like.

The presentation information control unit 105 interprets the presentation control information, and requests the filtering information control unit 109 to read the filtering information 400 from the filtering information holding unit 104, A request for creating and rewriting 400 is issued. Further, the presentation information control unit 105 compares the presentation conditions described in the presentation control information with the contents of the presentation control information, and according to the result, the presentation information holding unit 103.
Is also rewritten.

The filtering information holding unit 104 stores the filtering information 4 of the viewer who uses the information presentation apparatus 100.
00 and a filtering information description table 500.

Here, the configuration of the filtering information 400 will be described. FIG. 4 shows an outline of the filtering information 400, which is represented by a file name “filter1.fil”. Note that a plurality of pieces of filtering information can exist.

The filtering information 400 includes one or more common carrier filtering information 410 and one or more common carrier filtering information 420. Each of the common carrier filtering information 410 and the unique carrier filtering information 420 includes one or more filter fields 430. The company-specific filtering information 420 has a company code 421, and the company code 421 is used to specify a company that can use the company-specific filtering information 420. For example, when providing an advertisement service, a service provider that provides the service manages the provider common filtering information as filtering information common to all advertisements, while an advertisement provider (eg, a sponsor or the like) that provides each advertisement is In order to provide specialized filtering information closer to the contents of the advertisement, it is conceivable to acquire a business code and manage the business-specific filtering information for one's own advertisement.

The filter field 430 is classified into a fixed filter field 441 and a variable filter field 442. The fixed filter field 441 includes a field identifier 450 and one or more filter items 460, and the variable filter field 442 includes a field identifier 450.
50, version value 470 and one or more filter items 4
60. The field identification 450 is information for identifying a field. The filter item 460 corresponds to, for example, one item of the preference or attribute of the viewer, and is a minimum unit for performing editing in the filtering information 400. Fixed filter field 441 contains filter item 46
0 means that the meaning indicated by the preference or attribute of the viewer corresponding to the filter item 460 is fixed, and the variable filter field 442 indicates the version value 47.
By changing 0, the meaning indicated by the filter item 460 already used is changed, which means that the filter item 460 can be reused. Note that the fixed filter field 441 may also have a version value.

In FIG. 4, a filter field having a field identification of 1 is a fixed filter field of common carrier filtering information, a filter field of field identification 2 is a variable filter field of common carrier filtering information, The filter fields with identifications 3 and 4 are a fixed filter field and a variable filter field in the company-specific filtering information with the company code of 55, and the field identifications 5, 6, and 7 are the company fields with the company code of 18 These are a fixed filter field and a variable filter field in the original filtering information. Note that a plurality of variable filter fields having the same field identification and different version values may be stored. The filtering information control unit 109, which will be described later, can refer to not only the value of the filter item of the variable filter field of the new version value but also the value of the filter item of the variable filter field of the same field identification of the old version value from the content. It becomes possible.

An optional filter field has an expiration date (e
xpire). FIG. 4 shows that the expiration date of the filter field whose field identification is 3 is September 31, 2000. The expiration date may be given to not only the filter field but also a filter item unit, a common filtering information unit of a business operator, a filtering information unit of a business operator, and the entire filtering information (filter1.fil). In addition,
The expiration date is indicated by the date, but is not limited to this format.

The filter item 460 is filter item identification 4
61 and a bit pattern 462. The filter item identification 461 is information for identifying the filter item 460. The bit pattern 462 is a value in the filter item 460 identified by the filter item identification 461, and the bit pattern value and the value of the filter item correspond to, for example, an actual value corresponding to the meaning indicated by the preference attribute of the viewer. In FIG. 4, the bit pattern value of the filter item whose field identification is 1 and the filter item identification is 5 is 0001, the bit pattern value of the filter item whose field identification is 2, the version value is 1 and the filter item identification is 3 Is 1100. Note that the value of the filter item is not limited to a bit pattern. The bit pattern value of each filter item is NULL when not input
And

Although the value of the filter item is a bit pattern in this embodiment, the present invention is not limited to the bit pattern.

Although the filtering information for one viewer is represented in one file in FIG. 4, the filtering information for a plurality of viewers may be realized in one file. , Each version value, and each filter item may be realized by separate files.

In order for the presentation information control unit 105 to read the bit pattern value of a specific filter item, the file name of filtering information, field identification, company code, version value, and Specify the required filter item identification. For example, in the fixed filter field of the common provider filtering information, the file name, field identification, and filter item identification of the filtering information are specified, but a version value may be specified as necessary.
In the variable filter field of the company-specific filtering information, all of the file name, company code, field identification, version value, and filter item identification of the filtering information are specified.

The filtering information control unit 109 controls reading and writing of the filtering information 400 in accordance with a request from the presentation information control unit 105.
The filtering information setting unit 110 actually writes in the filtering information 400 according to the request of the filtering information control unit 109. Hereinafter, the filtering information 400 by the filtering information control unit 109 will be described.
The read and write control process of the first embodiment will be described.

(Processing of Filtering Information Control Unit 109) The filtering information control unit 109 sends the filtering information 40
0 is read and written. Hereinafter, a processing flow of the filtering information control unit 109 will be described with reference to FIG.

The filtering information control unit 109 determines whether the request from the presentation information control unit 105 is for the common carrier filtering information or for the unique filtering information of the company (step S6001).

First, the processing of the filtering information control unit 109 in the case where the request from the presentation information control unit 105 is to the common filtering information of the enterprise will be described. Filtering information control section 109 determines whether the request from presentation information control section 105 is for a fixed filter field or a variable filter field (step S).
6002). If the request from the presentation information control unit 105 is for the fixed filter field, it is checked whether an expiration date attribute is assigned, and if it is, it is determined whether it is within the expiration date (step S6003). If the expiration date has passed, the request is rejected.
The URL is returned to the presentation information control unit 105 (step S6004). If it is within the validity period, read out the filter item of the requested fixed filter field, and in the case of writing and editing, read and write the bit pattern value of the filter item corresponding to the specified field identification and filter item identification. Perform (Step S60)
05). In the case of writing, the filtering information control unit 1
09 issues a write request to the filtering information setting unit 110, and the filtering information setting unit 110 performs actual writing.

If the request from the presentation information control unit 105 is for a variable filter field, it is checked whether an expiration date attribute has been assigned. . If the expiration date has passed, the request is rejected.
The URL is returned to the presentation information control unit 105 (step S6004). If it is within the expiration date, it is determined whether the request of the presentation information control unit 105 is a read request or a write request (step S6007). In the case of a read request to the filter item of the variable filter field, the specified field identification, the filter item identification and the version value are compared with the version value of the corresponding variable filter field (step S6008). If they are equal, the bit pattern value of the corresponding filter item is read (step S6009). NULL if both are different
Is returned to the presentation information control unit 105 (step S60).
04).

In the case of a request to write a variable filter field into a filter item, the version value specified by the presentation information control unit 105 is compared with the version value of the variable filter field held by the filtering information holding unit (step S6010). ). In step S6010, if the both are equal, a write request is issued to the filtering information setting unit 110, and the bit pattern value of the corresponding filter item is rewritten to the specified value (step S6011). Step S6010
In the case where the two version values are different, a write request is issued to the filtering information setting unit 110,
The bit pattern values of all the filter items of the applicable variable filter field are rewritten to NULL, and the version value of the applicable variable filter field is rewritten to the version value designated by the presentation information control unit 105 (step S601).
2) Rewrite the bit pattern value of the corresponding filter item to the specified value (step S6011).

If the request from the presentation information control unit 105 is for the company-specific filtering information, the filtering information control unit 109 sets the company-specific filtering to which the field corresponding to the specified company code and field identification and filter item identification belongs. A comparison is made with the business code of the information (step S6013). If they are not equal, the request from the presentation information control unit 105 is rejected, and if it is a read request, NULL is returned (step S601).
4). If the carrier codes are the same, the process thereafter is the same as the process for the carrier common filtering information. In addition, in the above-described writing process of the filter item when the version values are different, the bit pattern values of all the filter items of the variable filter field are rewritten to NULL in the above, but the filter item whose question content does not change even if the version value changes. Need not be rewritten. Even if the version values are different, if the version value of the variable filter field is newer, the bit pattern value may be rewritten for the filter item whose question content is changed.
In addition, the filter item reading process in the case where the version values are different from each other returns NULL in the above description, but the filter item whose query content does not change even if the version value read and requested by the presentation information control unit 105 is newer. Is
The same processing as in the case where the two version values are equal may be performed.

Next, the filtering information description table 5
00 will be described. FIG. 5 shows an outline of the filtering information description table 500. The filtering information description table 500 contains the filtering information setting unit 1
10 is described for the purpose of securing a storage area for storing the filtering information 400 in the filtering information holding unit 104. The filtering information description table 500 is a prototype of the filtering information 400. The configuration of the common filtering information of the business, the configuration of the filtering information unique to the business, and the assignment to which advertisement provider, the configuration of each fixed filter field and each of the variable filter fields. Describe the configuration of

In FIG. 5, the filter-related information 501 defines a description method of the common filtering information of the service provider, and the filter-related information 502 is the filtering information of the service provider specific to the advertisement providing service indicated by the service code “55”. The description method is described, and the filter-related information 503 describes the description method of the company-specific filtering information dedicated to the advertisement providing company indicated by the company code “18”. Column 51
0 indicates the configuration of the fixed filter field and the variable filter field to be held as the common carrier filtering information and the unique carrier filtering information. The value "f"
“ixed” indicates a fixed filter field and “varia”
ble "indicates a variable filter field. A column 520 indicates the field identification of each field, a column 530 indicates the number of filter items constituting each field, and a column 540 indicates a bit of a bit pattern value of the filter item constituting each field. A number is shown, and column 550 shows the expiration date for each field.

In the example of FIG. 5, as the common filtering information of the business operator, the field identification is 1, the number of filter items is 13,
A fixed filter field of 4 bits for each filter item, a variable filter field of 4 filter items for field identification 2 and a 4 filter bit for each filter item are defined,
As the carrier-specific filtering information of the carrier code 55, a fixed filter field having 7 filter items with field identification 3 and 4 bits for each filter item, and 3 filter items and 4 bit bits for each filter item with field identification 4 Is defined as a fixed filter field having 5 filter items in field identification 5 and 4 bits in each filter item, and a field filter 6 as the unique filtering information of the company code 18.
And 7 define two variable filter fields in which the number of filter items is 3 and 4, and the number of bits of each filter item is both 4.

The filtering information setting section 110 reads out the filtering information description table 500 from the filtering information holding section 104 when the information presenting apparatus 100 is started up for the first time or when the filtering information description table 500 is updated. A storage area of the filtering information holding unit 104 is secured in a format, and filtering information is set. The filtering information setting unit 110 includes a filtering information description table 50.
The storage area of the filtering information holding unit 104 is released and secured only for the updated part of 0, and the part without change is not affected. The filtering information description table 500 stores the filtering information holding unit 104.
Is assumed to be pre-installed in advance,
It can also be replaced by broadcasting, other communication means, removable media, or the like. The filtering information setting unit 110 also writes the filtering information 400 held by the filtering information holding unit 104 according to the request of the filtering information control unit 109. In the write process, when the value of the specified filter item is written, and when the version value of the variable filter field of the write destination is different from the write version value, all the filter items of the specified variable filter field are temporarily N
There are two types of rewriting to UL, updating the version value of the specified variable filter field, and writing the value of the specified filter item.

In the following, input of viewer information to filtering information and switching of presentation information by comparison with filtering information will be described using interactive data and an example of an output screen based on the data.

(Example of Inputting Viewer Information in Filtering Information) FIG. 2 shows an example of interactive data for reflecting the viewer information in the filtering information, which is represented by a file name "enquire1.bml". . In FIG. 2, the interactive data is composed of presentation information and presentation control information. First, the presentation information will be described. The <p> tag means that the portion surrounded by the tag is one paragraph, and id = 2001 in the <p> tag indicates that the portion surrounded by the <p> tag is 2 paragraphs.

In the filtering information file represented by “fil”, it means that a request is made to acquire the bit pattern value of the filter item having the item identification of 1 in the fixed filter field having the field identification of the common filtering information of the operator being 1. The bit pattern value is stored in the variable “age”. get_common_variable
_Filter (filter1.filter, 2,1,
Similarly, 1) means that a request is made to obtain a bit pattern value of a filter item having an item identification of 1 in a variable filter field having a field identification of 2 and a version value of 1 in the common carrier filtering information. The stored bit pattern value is stored in a variable “seibetsu”.
getElementById (9001) means that the information indicated by the identification information 9001 of the presentation information is acquired. In this case, <a id = 9001 href

Similarly, the display character string of the <a> tag indicated by the identification information 9002 is set to “Introduction of drama program”, and the link destination file when the viewer selects the character string by remote control operation is set to “drama. bml ". After completing the interpretation of the presentation control information, the presentation information control unit 105 issues a control completion notification to the reproduction unit 107. Upon receiving the control completion notification, the reproduction unit 107 issues a display request for the presentation information stored in the presentation information holding unit 103 to the display unit 108, and the display unit 108 displays the presentation information on the screen. FIG. 14 shows ossumetv. 7 shows an example of a screen displayed after switching presentation information of a bml file. In this screen, when the viewer selects the “Introduction to drama program” character string by remote control, the viewer enters the “Introduction to drama program” character string in “jidaigeki.bml”, which is the linked file. Is selected by remote control operation, the link destination file "drama.bml"
Respectively.

Therefore, it is possible to change the presentation content of the presentation information according to the value of one or more filter items and display the information. In addition, it is also possible to change the presentation content of the presentation information and display it according to the values of the filter items in the plurality of fields. For example, in the case of an advertising service, the content of a filter item varies depending on the content of an advertisement target.
It is difficult to provide advertisements closer to the viewer's preference attributes. The content of the filter items prepared by each advertisement provider is very important as marketing information, and reference or writing from interactive data provided by other advertisement providers must not be performed. Information presentation device 10 of the present invention
No. 0 can hold the company-specific filtering information in the filtering information holding unit 104 so that each advertisement provider can use the dedicated filtering information. This vendor-specific filtering information can be accessed only with interactive data provided by the advertising provider with the corresponding vendor code, and the use of new filter items and the reuse of used filter items are independent. This does not affect the common carrier filtering information or other carrier-specific filtering information.

Next, input of the viewer information into the filter items of the fixed filter field and the variable filter field of the filtering information unique to the provider, which can be stored in the filtering information storage unit 104 by the provider of each content, and The switching of the presentation information based on the comparison with the filtering information will be further described using another interactive data and an example of an output screen.

(Example of inputting viewer information to business-specific filtering information) FIG. 15 shows a file name "enquate".

The four types of “wagon” and “RV” are selected using the four-color button 310 of the remote controller. 18 in FIG. In the bml screen example, the viewer's impression of the new car "Carrara" is selected from "I want it immediately", "Look at the catalog", "I am not interested", and "I want another car" using the four-color button 310 on the remote control. Represents

Since these two questionnaires are closely related to automobiles and have little effect on advertisements in other fields, there is little need to store them in the common company filtering information. In addition, the contents of these questionnaires are based on the automobile manufacturer "TOY
It becomes important marketing information for "OTO", and it is desired that it is not referred to or edited by other advertisement providers. Therefore, the answers to these three questionnaires should be stored in the company-specific filtering information. The filtering information control unit 109 controls the access to the filtering information unique to the business operator using the business code so that the filtering information control unit 109 can access only the business providing the questionnaire. The question about the favorite model of "enquate11.bml" is a common and invariant question content for TOYOYO, while "enquire12.bml"
The "ml" new car impression question is a temporary question.
Therefore, by storing the response result of “enquate11.bml” in the fixed filter field of the provider-specific filtering information and the response result of “enquire12.bml” in the variable filter field of the provider-specific filtering information, respectively, Invariant question content remains fixed, temporary question content is TOYOT
It can be updated according to the contents of the advertisement provided by Company O.

In this function, if the version value of this variable filter field is other than 1, the content indicated by the filter item of item identification 1 is different from the case of version value 1, so that the bit pattern value of this filter item is not read and NULL is returned. . Similarly, it is not possible to access the company-specific filtering information of the company code “55”.

The above-described enquate11. bml and enquate12. The reproduction unit 107, the presentation information control unit 105, and the filtering information control unit 109 when the viewer selects the desired car type and the impression of the new car "Carrara" in bml and presses the four-color button 310 of the remote control button, respectively. toyoto.

liter1. In the “file”, the filtering information control is performed on the request for acquiring the bit pattern value of the filter item identification 1 of the fixed filter field having the field identification 5 of the operator-specific filtering information indicated by the operator code “18” of the <body> tag. Put it out in section 109. The filtering information control unit 109 checks whether the requested fixed filter field exists, and if so, reads out the bit pattern value of the specified filter item with the filter item identification 1 and returns it to the presentation information control unit 105. Therefore, “0100” is stored in the variable “cartype”.

The presentation information control unit 105 sets the function “get_p
"filter_variable_filter", the filtering information file "filter"

A request to acquire the bit pattern value of the filter item identification 1 when the variable filter field having the version value of 1 is issued to the filtering information control unit 109. The filtering information control unit 109 checks whether the requested variable filter field exists, and if so, checks whether the version value of the variable filter field is equal to the specified version value “1”. In this case, NULL is returned. If they are equal to each other, the bit pattern value of the specified filter item of the filter item identification 1 is read and returned to the presentation information control unit 105. Therefore, “1000” is stored in the variable “carara”.
In the branching process 2101, the presentation information control unit 105 determines that the variable “cartype” is “0100” (a favorite vehicle is a sports car), and thus the presentation information control unit 105 indicates the identification information 1951 <
a> The display character string of the tag is replaced with “introduction of sports car”, and the link destination file when the viewer selects the character string by remote control operation is replaced with “sports.bml”.

In the branching process 2102, the presentation information control unit 1
05, the variable “carara” is “1000” (“I want it immediately”), so the display character string of the <a> tag indicated by the identification information 1952 is changed to “special information for those planning to purchase a new carrara”. The link destination file when the viewer selects the character string by remote control operation is "spec

The presentation information control unit 105 controls the change_change_
After executing the carinfo function, a control completion notification is issued to the reproduction unit 107. Upon receiving the control completion notification, the reproduction unit 107 issues a display request for the presentation information stored in the presentation information holding unit 103 to the display unit 108, and the display unit 108 displays the presentation information on the screen. FIG. b
13 shows an example of a screen displayed after switching presentation information of an ml file. In this screen, when the viewer selects the “introduction to sports car” character string by remote control operation, the process transits to “sports.bml” which is a link destination file.

In this example, “enquire12.bm
l ”, the viewer pressed the blue button 311.
In FIG. 23, "special information for those who are planning to purchase a new carrara" is displayed. However, if any other button is pressed, or the version value of the variable filter field in the field 6 of the company-specific filtering information is specified. If the version value is different from “1”, the variable “carar
Since "a" contains a value other than "1000" (including NULL), "new" carrara "announcement" originally described in the presentation information is displayed as a default.
FIG. 24 shows an example of this default displayed screen. In this way, it is possible to present a special display and a link for some viewers who have given a specific answer, and to provide a display and a link for everyone else.

In the advertising service, interactive data is successively created as a new questionnaire as time elapses, and the viewer is answered, and a value is input to a new filter item. Can be provided. “Enqu” in FIG.
ate12. bml ", the response result is set for the filter item 1 in the variable filter field. However, if the advertisement provider subsequently carries out a new questionnaire with different interactive data, the filter The item identifications are added one by one, and the filter item identifications 2, 3, 4,. . . Create interactive data to set the answer result for. However, since the number of filter items in each variable filter field of the filtering information is finite, all the filter items are already used, and further filter items may be required. In this case, it is necessary to reuse the filter items.

However, since the content and meaning of the filter item change before and after reuse, there is a possibility that the presentation control information for reading the bit pattern value of the filter item may read the answer result (bit pattern value) for the different content. For this reason, when describing a write request to the bit pattern value of the filter item of the variable filter field in the presentation control information, be sure to specify the version value, and if all the filter items of the variable filter Is used, a version value obtained by adding 1 to the version value of the variable filter field held by the filtering information holding unit 104 is designated.

Upon receiving a request from the presentation information control unit 105 to write to the filter item of the variable filter field, the filtering information control unit 109 stores the requested version value in the variable filter field held by the filtering information holding unit 104. If the value is larger than the version value, it is interpreted as the reuse of the filter item of the designated variable filter field, and a write request is issued to the filtering information setting unit 110. Once NU
LL, the requested version value is set to the version value of the designated variable filter field, and the value is set to the requested filter item. This is shown in FIG.

To read the updated filter item value of this variable filter field from the presentation control information, a new version value is specified. When an old version value is specified, NULL is read. As a result, the content of the filter item read by the presentation control information is inconsistent, that is, the content of the filter item intended by the presentation control information when read is inconsistent with the content of the filter item intended by the actually read value. prevent.

For example, in the case of an advertisement service, a temporary advertisement such as an introduction of an event or an event is provided, an advertisement is provided only during a certain period, or an advertisement is limited to a certain period. It is also assumed that an advertisement is provided for a product only during that period. In this case, the corresponding filtering information may be valid only during that period. Thus, the filtering information can have an expiration date attribute. In FIG. 4, “expire =“ 00/09 ”of the fixed filter field of field identification 3 of the company-specific filtering information of the company code“ 55 ”.
/ 31 "" indicates the expiration date attribute of this field, and means that the fixed filter field of field identification 3 is valid until September 31, 2000. Similarly, the variable filter field of field identification 4 means that it is valid until September 31, 2000. In this example, the expiration date attribute is assigned to each field. However, the expiration date attribute is not limited to the field, may be for each filter item, may be for each company-specific filtering information, may be for each company-common filtering information, The whole filtering information may be used.

Next, the version management and the expiration date management of the variable filter field by the filtering information control unit 109 will be further described using another example of interactive data and an example of an output screen.

From the "hard image", the four-color button 310 on the remote control
Is used to make a selection. The intent of this questionnaire is to display a link to a special gift announcement only to viewers who responded to the questionnaire.

These two questionnaires are also closely related to automobiles, and are important marketing information for the automobile manufacturer “TOYOTO”. It is desired that other advertisement providers do not refer to or edit the information. Therefore, the answer results to these two questionnaires are described in the interactive data so as to be stored in the variable filter field of the company-specific filtering information. Here, the variable filter field of the field 6 of the company-specific filtering information in which the company code of the filtering information held by the filtering information holding unit 104 is “18” has a version value of 1, and the filter item identifications 1 to 3 The filter items have already been set to enquate12. It is assumed that bit pattern values are stored in bml and interactive data of another questionnaire as shown in FIG. In this case, en in FIG.
state21. The purpose of bml is to store the answer result in the filter item identification 4 of the same variable filter field. In addition, in FIG. bm
1 assumes that all filter items (filter item identifications 1 to 4) of this variable filter field have already been used, raises the version value of this variable filter field to 2, and sets filter item 1 to a new questionnaire. The purpose is to change to items (TOYOTO car impression). Further, the expiration date attribute “expire” is set to “00/09/31” in this variable filter field, which means that the filter item of this variable filter field is valid until September 31, 2000.

Thereafter, the viewer follows the display of FIG. 28 and FIG. bml, the blue button 311 on the remote control is

The filtering information control unit 109 compares the company code received from the presentation information control unit 105 with the company code held by the filtering holding unit. If the two are equal, the specified version value is compared with the version value of the requested variable filter field. If the two are equal, a write request is issued to the filtering information setting unit 110 and the specified filter item identification 4 Set the first bit of the filter item. When the other four-color buttons are pressed, the same process is performed, and only the bits of the filter items whose values are finally set are different.

In this case, since the filter item of item identification 4 which has not been used is only newly used, the version value is not updated.
te12. The filter item with filter item identification 1 of the variable filter field with the same field identification 6 already used in bml is not affected.

FIG. 31 shows that the viewer follows the display in FIG. 28 by pressing the blue button 311

The provider code “18” described in the presentation information is output to the filtering information control unit 109. The filtering information control unit 109 compares the company code received from the presentation information control unit 105 with the company code held by the filtering holding unit. If the two are equal, the specified version value is compared with the version value of the variable filter field of the requested field identification 6, and for the specified version value 2, the filtering information holding unit 10
Since the version value of the variable filter field held by No. 4 is 1, the filtering information control unit 109 interprets that the variable filter field is reused, issues a write request to the filtering information setting unit 110, and issues a field identification 6 Is rewritten to NULL (unused state), the version value of the variable filter field is set to 2, and the third bit of the requested filter item 1 is set. When the other four-color buttons are pressed, the same process is performed, and only the bits of the filter items whose values are finally set are different.

FIG. 32 shows how the filtering information file "filter1.fil" changes when the viewer presses the green button 313 on the remote controller (the impression of a TOYOTO car is "cheap") in accordance with the display of FIG. FIG. In this case, since all the filter items of the variable filter field of the field identification 6 are cleared once, for example, the content of the question of the filter item of the filter item identification 1 is “enquire12. The new "TOYO" instead of the "impression of a new car carrara" at bml

er (filter1.fil, 6, 1, 1) has a field identification of 6 in the filtering information file “filter1.fil” of the company-specific filtering information corresponding to the company code “18” of the <body> tag. Variable filter field version value is 1
Means that a request is made to acquire the bit pattern value of the filter item whose item identification is 1, and the acquired bit pattern value is stored in the variable “carara”. In this function, if the version value of this variable filter field is other than 1, the content indicated by the filter item of item identification 1 is different from the case of version value 1, so that the bit pattern value of this filter item is not read and NULL is returned. . Further, since the provider code attribute of the <body> tag of the presentation control information is “18”, it is not possible to access the provider-specific filtering information of the provider code “55”.
get_provider_variable_fil
The same applies to ter (filter1.fil, 6, 1, 4). getElementById (3352) means that the information indicated by the identification information 3352 of the presentation information is obtained. In this case, <a id = 3352
href = “catrv.bml”> Car TV introduction <
/ A> and substitute it for the variable “yohin”. Yohin. style. visibility = ”
"invisible" means that the display character string "car TV introduction" of the information indicated by the identification information 3352 is made invisible. When this processing is performed, the character string “Introducing Car TV” is not displayed on the screen, and it is not possible to transit to the link destination file “cartv.bml” corresponding to the character string.

The above-mentioned enquire21. The reproduction unit 107, the presentation information control unit 105, and the filtering information control unit 10 when the viewer selects the desired car article and presses the four-color button 310 of the remote control button in bml.

The presentation information control unit 105 reads the presentation control information output from the reproduction unit 107. In this example, onload is added to the <body> tag of the presentation information.
Since the attribute is described, the reproduction unit 107 requests the presentation information control unit 105 to execute the attribute value change_carinfo function.

The presentation information control unit 105 sets change_c
Execute the arinfo function. In the process 3321, the presentation information control unit 105 determines the function “get_provider_
According to variable_filter, in the filtering information file “filter1.filter”, filter item identification 1 in the case where the variable filter field of field identification 6 of the company-specific filtering information indicated by the company code “18” has the version value 1 To the filtering information control unit 109. Filtering information control unit 1
In step 09, it is checked whether or not there is a variable filter field in the field 6 of the company-specific filtering information of the received company code "18". If the variable filter field exists, its validity period attribute is read to check whether it is before the validity period. If the validity period has passed, NULL is returned to the presentation information control unit 105 and the variable “ca
“rara” stores NULL. On the other hand, if it is before the expiration date, the filtering information control unit 109
It checks whether the version value of the variable filter field is equal to the specified version value “1”, returns NULL if they are not equal, and returns NULL if they are equal.
The bit pattern value of the designated filter item identification 1 is read and returned to the presentation information control unit 105. Therefore, the variable "c
“arara” stores “1000”.

The presentation information control unit 105 executes the process in the process 3331 in the same manner as the process 3321. The filtering information control unit 109 checks whether or not there is a variable filter field of the field 6 of the company-specific filtering information of the received company code “18”. If the variable filter field exists, its validity period attribute is read to check whether it is before the validity period. If the validity period has passed, NULL is returned to the presentation information control unit 105, and the variable Is NUL
L is stored. On the other hand, if it is before the expiration date, the filtering information control unit 109 sets the version value of the variable filter field to the specified version value “1”.
Checks whether they are equal to each other, and if they are not equal, NULL
If they are equal, the bit pattern value of the designated filter item identification 4 is read and returned to the presentation information control unit 105. Therefore, “1000” is stored in the variable “carryohin”.

In the branching process 3301, the presentation information control unit 1
05, when the variable “carara” is “1000” (“I want it immediately”), the display character string of the <a> tag indicated by the identification information 3351 is changed to “special information for those planning to purchase a new carrara”. And the link destination file when the viewer selects the character string by remote control operation is "spec

Is not “1000”, nothing is performed. In this case, the display character string of the <a> tag and the link destination file indicated by the identification information 3351 are the display character string “new type“ color color ”originally described in the presentation information. "Announcement" and the link destination file "newcarara.bml" remain.

In the branching process 3302, the presentation information control unit 1
05 is “1000” for the variable “carryohin”

The version value of the variable filter field whose field identification of the unique filtering information corresponding to 8 ″ is 6 is 2, and the bit pattern value of the filter item whose item identification is 1 is requested to be obtained. The stored bit pattern value is stored in the variable “insho”. In this function, if the version value of the variable filter field is other than 2, the content indicated by the filter item of item identification 1 is different from the case of version value 2, so that the bit pattern value of this filter item is not read and NULL is returned. . get_provider_variable_f

In the above-described enquot22. bml by the playback unit 107, the presentation information control unit 105, and the filtering information control unit 109 when the viewer selects the impression of a TOYOTO car and presses the four-color button 310 of the remote control button.
The interpretation and presentation processing of bml are shown below. Where t
oyotogentei2. Since the variable filter field of the field identification 6 of the company code “18” referred to by the bml has the expiration date attribute “00/09/31”, the timing of reading the interactive data differs before and after the expiration date. The outline of the processing in both cases is described below.

(Processing when green button 313 is pressed in "enquire22.bml") The bml file is read from the reception information storage unit 102 and the presentation information is output to the presentation information holding unit 103. The playback unit 107 is a
ntei2. The presentation control information is output to the presentation information control unit 105 from the bml file. The presentation information control unit 105 reads the presentation control information output from the reproduction unit 107. In this example, onload is added to the <body> tag of the presentation information.
Since the attribute is described, the reproduction unit 107 requests the presentation information control unit 105 to execute the attribute value change_carinfo function.

The presentation information control unit 105 sets change_c
Execute the arinfo function. The presentation information control unit 105 uses the function “get_provider_variable_

When the variable filter field having the field identification 6 has the version value 2, the request for acquiring the bit pattern value of the filter item identification 1 is sent to the filtering information control unit 109.
Put out The filtering information control unit 109 checks whether or not there is a variable filter field of the field 6 of the company-specific filtering information of the received company code “18”. If the variable filter field exists, read its expiration date attribute to see if it is before the expiration date,
If the expiration date has passed, the presentation information control unit 105
NULL is returned to the variable "insho"
LL is stored. On the other hand, if it is before the expiration date, the filtering information control unit 109 checks whether the version value of the variable filter field is equal to the specified version value “2”.
If the values are equal, the bit pattern value of the designated filter item identification 1 is read and returned to the presentation information control unit 105. Therefore, the variable “insho” contains “0”
010 "(the impression of a TOYOTO car by pressing the green button is" cheap ") is stored.

In the branch processing 3601, the presentation information control unit 1
05 indicates that the variable “insho” is not NULL (enq

The display string of the tag is "Notice of special gift",
Also, the link destination file when the viewer selects the character string by remote control operation is replaced with “present.bml”.

On the other hand, when the variable “insho” is NULL (e

Output to the control unit 109. The filtering information control unit 109 checks whether or not there is a variable filter field of the field 6 of the company-specific filtering information of the received company code “18”.
If the variable filter field is present, the validity period attribute is read to check whether it is before the validity period.
LL is returned, and NULL is stored in the variable “insho”. On the other hand, if it is before the expiration date, the filtering information control unit 109 checks whether the version value of the variable filter field is equal to the specified version value “1”, and returns NULL if they are not equal, If they are equal, the bit pattern value of the designated filter item identification 1 is read and returned to the presentation information control unit 105. Therefore, “1000” (“I want the impression of the new carrara immediately”) is stored in the variable “insho”.

The presentation information control unit 105 further sets the variable “insho” to “1000” by branching processing 3602.
(“I want it immediately”), so the display character string of the <a> tag indicated by the identification information 3651 is “special information for those who are planning to purchase a new carrara”, and the linked file is “special.bml”. To ". If the variable "insho" is any other value, nothing is performed, and the character string displayed on the screen remains the "new" carrara "announcement" originally described in the presentation information. The previous file also remains “newcarara.bml”.

[0112] The presentation information control unit 105 controls the change_
After executing the carinfo function, a control completion notification is issued to the reproduction unit 107. Upon receiving the control completion notification, the reproduction unit 107 issues a display request for the presentation information stored in the presentation information holding unit 103 to the display unit 108, and the display unit 108 displays the presentation information on the screen. 37, 38, and 39 show toytogentei2. Before the expiration date of the variable filter field of the filter identification 6 (FIG. 3)
7), before the expiration date but enquote 22. 39 is an example of a screen displayed after switching of presentation information when the questionnaire of bml is not answered (FIG. 38) and when it is read after the expiration date (FIG. 39). In this example, enqua
te22. bml, the variable filter field of filter identification 6 is upgraded,
The presentation information is switched according to the answer of the new questionnaire "TOYOTO's impression of the car", and the display screen example is as shown in FIG. enquate22. If no response is made to the BML, the variable filter field of the filter identification 6 remains at the version value 1, and the presentation information is switched according to the response to the previous questionnaire "Impression of the new" Carrara "" and displayed as shown in FIG. This is a screen example. Also, after the expiration date of this variable field,
ei2. When the bml file is read, the results of both the old and new questionnaires are not obtained, and the presentation information is not switched and the default display is a display screen example as shown in FIG.

In the present embodiment, the presentation information and the link destination file name are changed depending on the filtering information, but the present invention is not limited to this. Further, in the present embodiment, it is possible to hold an expiration date in each field, but it is also possible to describe an activation time indicating a time when the field becomes available. At this time, if the time is earlier than the activation time, the field having the activation time cannot be accessed. Further, both the expiration date and the activation time may be held.

In this embodiment, only the character string is switched in the switching of the presentation information. Rewriting the display and the like can be realized by the same method. As described above, not only the method of presenting the link information but also the presenting method may be used to change the link destination address. Also, both the presentation method and the link destination address may be changed. In the present embodiment, the interactive data for inputting the viewer information in the filtering information and the interactive data for rewriting the presentation information with reference to the input filter filtering information are divided. Both may be realized.

When the viewer information is input to the filtering information, there is no filter item indicated by the specified filter item identification of the specified version value of the specified field of the specified filtering information file. In such a case, a new filter item may be created.

In this embodiment, the operator code is set to a numerical value and only the access to the filter field having the same operator code is permitted, but the present invention is not limited to this. The business code may be a bit pattern or a character string. Further, when the company code satisfies a certain condition, access to the filter field may be permitted.

The present invention may be realized by installing a program for realizing the same function as the information presenting apparatus in a general-purpose computer.

In the interactive data for inputting the viewer information to the filtering information, the filtering information is written in correspondence with the four-color button 310 of the remote controller. It may be associated with a button operation.

In this embodiment, the number of filter items in each field is fixed, but may be variable. Also, the bit pattern of each filter item may be fixed length or variable length.

The input of the viewer information to the filtering information may be realized by software embedded in the present information presenting apparatus.

[0121]

As described above, according to the present invention,
Multiple content providers can manage, refer to and edit their own filtering information, have filtering information that is more closely related to the content of their content, and realize content presentation that more closely matches the viewer's taste attributes . Since the filtering information unique to each content provider can restrict reference and editing from the content of another provider, it is possible to prevent leakage of the filtering information as important marketing information. In addition, by having multiple temporary or time-limited filtering information and reusing it, the storage area with a small number of receiving terminals can be used efficiently, and temporary or time-limited content can be added to the viewer's preference attribute. A presentation that fits can be made. In addition, by providing the filtering information with an expiration date, the advertisement provider can use the filtering information for a limited time.
