And an optical reading code generating means for generating the optical reading code based on the text data, and a display means for displaying the generated optical reading code.

[0014] When it is determined that a predetermined condition is satisfied based on data acquisition history information by data broadcasting or data communication stored in the terminal device, the terminal device adds the received text data to the received text data. Based on this, an optical reading code is generated. As a result, the optical reading code is generated and displayed only when it is determined that the predetermined condition is satisfied.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a schematic configuration of the entire system according to the first embodiment of the present invention.

[0026] This system receives a broadcast data from a broadcast station 10 and radio waves from the broadcast station 10. A broadcast receiver 20 having a function, a mobile terminal 30, and a Web server 50 connected to the mobile terminal 30 via a network 40 are configured. In this example, the broadcast receiver 20 is assumed to be a television device having a data broadcast reception function. The mobile terminal 30 is assumed to be a terminal device such as a mobile phone with power. As an optical reading code, a two-dimensional code will be described as an example.

[0027] The broadcast receiver 20 includes a broadcast receiver 21 that receives television broadcasts and data broadcasts, and specific data received by the data broadcast (two-dimensional code source data that is the source of the two-dimensional code).

By taking a picture of the two-dimensional code and displaying the two-dimensional code on the display screen of the mobile terminal 30 or accessing a website corresponding to the two-dimensional code, the two-dimensional code is attached. Information and services can be used.

[0030] Thus, in the present invention, since the two-dimensional code is transmitted from the broadcasting station 10 as text data for generating image data rather than being transmitted as image data, the number of two-dimensional codes is large. However, the size of the broadcast data itself can be small. Information provision The processing load for generating a large number of image data on the user side is also reduced. The user of the mobile terminal 30 does not need to manually input information on the terminal, and simply inputs the necessary information (for example, a telephone number or URL) by taking a two-dimensional code image with the camera unit. be able to. In addition, the mobile terminal 30 can only shoot a two-dimensional code for the time being, and the act of using it can be performed regardless of time and place.

[0038] Hereinafter, some operation examples of the present embodiment will be described.

FIG. 4 is a flowchart showing main operations of the broadcast receiver 20. When the broadcast receiving switch (not limited to a hardware switch but also includes a switching operation by menu selection, etc.) by the broadcast receiver 20 is turned on, this processing is started. First, the broadcast tuner in the broadcast receiving unit 205 is activated (Sl l). As a result, reception of broadcast data is started (S12). Broadcast data interpretation · The received broadcast data is displayed by the display program. The data is analyzed and it is monitored whether there is a two-dimensional code generation instruction in the received data (S13). If it exists, a two-dimensional code is generated by the two-dimensional code generation program in the two-dimensional code generation unit 23 (S14).

[0040] In data broadcasting, a two-dimensional code generation program (Fig. 2) is created by including the following tagged description in a document described in a markup language such as BML (Broadcast Markup Language). A two-dimensional code (image data) can be generated using.

, Object type = image / χ-netfront-qrcode>

^ param name = code value = secondary key ¹ ~ data ¹ ~ data valuetype = data />

[0041] In this example, a display target is instructed by a description element called an object, and display processing is started in response to this. In addition, "image / x_netfront-qrcode" is a tag based on the extended specifications of NetFront (registered trademark), a browser made by iACCESS, Inc. Is shown. aramname = "code" indicates that the value (value) following it represents a code, and valuetype = "data" indicates that this value is a data attribute.

[0042] The "two-dimensional code data" of this value is data to be two-dimensionally encoded, and is typically text data such as characters, symbols, numbers, etc., but includes image data. You can also. In the text example, if a telephone number is included as text data, a two-dimensional code corresponding to the telephone number is displayed. If the URL contains alphanumeric characters, the two-dimensional code corresponding to the URL is displayed.

[0043] In addition to the object as in this example, it is also possible to issue a two-dimensional code generation 'display instruction by a script alone. In particular, the dynamic generation instruction of the two-dimensional code in the present invention is performed by using a script (script) created in a language such as JavaScript (registered trademark) or ECMAScript as instruction information included in broadcast data. be able to. Scripts are defined with tags such as script></script> and can be included in broadcast data (for example, BML documents). That is, according to the reference data according to the script, the process of selecting or adding partial data to the two-dimensional code source data is performed on the screen. The two-dimensional code displayed on the screen can be dynamically changed.

In step S13, if there is no two-dimensional code generation instruction, the process proceeds to step S15. In step S15, broadcast data is displayed. If the process has moved from step S14, the two-dimensional code is displayed as an image together with the broadcast data. Also, broadcast data is displayed as usual. Until the process is terminated by turning off the broadcast receiving switch or turning off the power of the terminal device (S16), the process returns to step S12 and the above process is repeated.

[0045] The present invention is characterized by the two-dimensional code generation processing in step S14, and a specific example thereof will be described below.

FIG. 5 shows a conceptual diagram of the two-dimensional code generation processing in the present invention. In the present invention, instead of generating the two-dimensional code by the information provider side device, the original data for that purpose is transmitted to the receiver side device, and the two-dimensional code is generated by the receiver side device. In other words, the two-dimensional code original data 51b is received together with the instruction information 51a that does not simply convert the two-dimensional code original data into a two-dimensional code, and converted into a two-dimensional code in consideration of the receiver side reference data 53. The final two-dimensional code original data to be obtained is obtained, and the final two-dimensional code original data is converted into the two-dimensional code data 54 by the two-dimensional code generation program. The received two-dimensional code source data may correspond to one two-dimensional code or may correspond to a plurality of two-dimensional codes. In some cases, it corresponds to a part of one two-dimensional code.

[0047] When the two-dimensional code source data includes data specifying a plurality of two-dimensional codes, the reference data determines the selection conditions for the plurality of two-dimensional codes, and the reference data includes the two-dimensional code source data. Dimension code source data can be supplemented, 2D code generation conditions can be determined, and 2D code display attributes can be determined. In addition, as data to be supplemented, data obtained by the receiver side device may be used as it is, or randomly generated data may be used.

[0048] Examples of reference data include data stored in the receiver side device (region code, date / time data, etc.), data input by the user on the user side device (ID data, etc.), predetermined data Examples include judgment data for judging conditions. Judgment data is used, for example, Some event data in the person-side apparatus, for example, history information such as viewing and reception may be accumulated. An example is also possible in which the discount rate of coupon data specified by the two-dimensional code source data is randomly generated within a predetermined range. Furthermore, the type, function, and setting information of the terminal device can be used as other reference data. The types of terminal devices are different from fixed televisions, mobile phones, car navigation devices, PDAs, etc. The functions of the terminal device are the size of the display screen and specifications (memory capacity, communication speed, etc.). The setting information is contents that the user can set for the terminal device. For example, wide display setting, mute setting, subtitle presence / absence setting, language setting, power saving mode setting, TV's data broadcast double display Settings, adult prohibition settings, URL two-dimensional code conversion display settings, etc.

[0049] FIG. 6 shows the correspondence to a plurality of two-dimensional codes by using data representing a region (zip code as a region code) and data representing a time (for example, a day of the week) set in a broadcast receiver as reference data. In this example, the target data part is selected from the two-dimensional code source data. This figure describes three specific examples of selecting a data portion based on reference data.

[0050] In the first example, a broadcast receiver receives a data broadcast 51 including two-dimensional code original data corresponding to a plurality of two-dimensional codes and predetermined instruction information 52 by data broadcasting. The instruction information in this example is to select the reference data 53 of the two-dimensional code original data corresponding to a plurality of two-dimensional codes as a selection condition and select data that matches the selection condition.

[0051] The data broadcasting 51 in the first example includes a plurality of pairs of postal code (region code), branch name, and telephone number of the branch location in each area of a specific bank as the two-dimensional code source data. Includes text data 52a. In this case, the local postal code data 53a is stored as reference data in the receiver. In response to the above instruction, the two-dimensional code generator 23 extracts the branch name and telephone number corresponding to the corresponding postal number from the text data 52a using the postal code data 53a as the reference data 53, and this telephone number. Convert the number into a two-dimensional code. Display information 54 including the two-dimensional code and text data is sent to the display unit 25 and displayed as shown in a screen example 54a. The two-dimensional code 55a is displayed as an image. By photographing this two-dimensional code with the camera unit of the portable terminal 30, the telephone number can be accurately taken into the portable terminal 30 where the user needs to memorize it or manually input it. You can also make a call immediately to the phone number you have imported, or register it in the phone book in memory.

[0052] The data broadcasting 51 in the second example is text data including a plurality of combinations of postal codes (region codes) of store locations in various locations of a specific store, store names, and URLs as two-dimensional code source data. 52a. In this case, the two-dimensional code generation unit 23 uses the postal code data 53b as reference data 53, extracts the store name and URL corresponding to the postal code from the text data 52b, and uses this URL as the URL. Convert to 2D code. The display information 54 including this two-dimensional code is sent to the display unit 25 and displayed together with other information like the two-dimensional code 55b on the screen 54b. The viewer can capture the two-dimensional code with the camera unit of the mobile terminal 30 and accurately capture the URL into the mobile terminal 30 where the user needs to memorize or manually input the URL. The two-dimensional code 55b is displayed as an image. You can also access the imported URL immediately or register it in the address book in memory.

[0053] The data broadcasting 51 of the third example includes text data 52c including a plurality of pairs of days of the week and passwords as the two-dimensional code original data. In this case, the two-dimensional code generation unit 23 uses the day-of-week data 53c as reference data 53, extracts a password corresponding to the day of the week from the two-dimensional code original data and the display instruction information 52b, and outputs the password. Is converted into a two-dimensional code. The display information 54 including this two-dimensional code is sent to the display unit 25, and is displayed together with other information like the two-dimensional code 55c on the screen 54c. The viewer can accurately capture the secret word into the portable terminal 30 that the user needs to memorize or manually input by photographing the two-dimensional code with the power unit of the portable terminal 30. The two-dimensional code 55c is displayed as an image. Also, the captured password can be displayed and read by other code readers.

[0054] FIG. 7 shows an example in which the time data at that time obtained from the date / time data obtained in the broadcast receiver is used as the reference data. In this figure, an example of extracting two-dimensional codes based on data portions that differ in time zone based on reference data is extracted. Light up.

[0055] For example, when the data broadcast 71 is once recorded in the recording device 79 and reproduced, the time zone actually broadcast may be different from the reproduced time zone. In addition, the same data can be broadcast at different times. Therefore, the data broadcast 71 includes information that differs depending on the time zone, in this example, contact information and business time information according to the business hours, as the two-dimensional code source data and the instruction information 72. The instruction by this instruction information is to select a contact corresponding to the time zone including the time data 73a at the time of reproduction and use it as the original data of the two-dimensional code. In response to this instruction, the two-dimensional code generation unit 23 uses the playback time data 73a as the reference data 73 to determine whether the time is within business hours or external force from the data 72, and the corresponding contact address. Is extracted and converted into a two-dimensional code. Display information 74 including the two-dimensional code is sent to the display unit 25. The display unit 25 displays the two-dimensional code 75 together with other information as shown on the screen 74 a. The viewer can capture the telephone number in the terminal by photographing the two-dimensional code 75 with the camera unit.

FIG. 8 is a flowchart showing the two-dimensional code generation process (1) in the receiver 20 corresponding to the example using the postal code shown in FIG.

[0057] First, the received broadcast data 51 is interpreted (S21), and it is checked whether there is a selection display instruction based on the zip code (S22). If not, a normal two-dimensional code generation process is executed (S23). If there is a selection display instruction based on the zip code, it is checked whether the zip code data can be acquired in the receiver 20 (S24). If it cannot be obtained, error data is generated and the process is terminated (S26). If the zip code data can be obtained, it is checked whether a two-dimensional code can be generated based on the zip code (S25). If possible, a two-dimensional code is generated based on the two-dimensional code source data obtained corresponding to the postal code (S27). If it is not possible, error data is generated (S26).

[0058] The examples shown in FIGS. 6 (c) and 7 are substantially the same as those shown in FIG. 8 except that the types of reference data are different.

FIG. 9 shows that the reference data generation unit 24 uses the ID holding unit 9 held by the user as reference data.

An example of reading and using user-specific identification information (ID) from 3 is shown below. That is, this The reference data in this case is data input from the outside into the receiving apparatus. The ID holding unit 93 can have various forms, such as a non-contact IC card or a terminal having this function), a contact IC card, a magnetic card, an RF tag, a terminal with an IrDA output function, etc. is there. The reference data generation unit 24 is a data reader (corresponding to the ID reader 209 in FIG. 2) corresponding to such various forms. The two-dimensional code generator 23 generates two-dimensional code data based on the two-dimensional code and instruction information 92 obtained from the data broadcast 91 and the reference data 95 which is HD information obtained by the reference data generator 24. . This is sent to the display unit 25 as display information 96 and displayed. As a method for generating a two-dimensional code, one of a plurality of two-dimensional code source data is selected based on reference data (Π3 information) as in the above example. Alternatively, HD information is added to the two-dimensional code source data as described later.

FIG. 10 is a flowchart showing the two-dimensional code generation process (2) in the receiver 20 corresponding to the example shown in FIG.

[0061] First, the received broadcast data is interpreted (S31), and the force for the selection display instruction based on the ID is checked (S32). If not, normal two-dimensional code generation processing is executed (S33). If there is a selection display instruction based on the ID, it is checked whether the ID data can be acquired in the receiver 20 (S34). If it cannot be obtained, error data is generated and the process ends (S37). If ID data can be acquired, it is checked whether a two-dimensional code can be generated based on the ID data (S35). If possible, a two-dimensional code is generated (S36). If not possible, error data is generated (S37).

[0062] FIG. 11 shows an example in which the reference data is used as determination data for determining a predetermined condition. The judgment data in this example uses, as some event data in the user side device, cumulative storage of history information such as viewing and reception.

[0063] Broadcast data 81 in this example includes instruction information for instructing to record viewing history information together with the broadcast data. Similarly, the broadcast data 82 broadcast after the broadcast data 81 includes instruction information for instructing to record the viewing history information. Furthermore, the broadcast data 83 includes instruction information that “a two-dimensional code generation condition can be determined” in addition to an instruction to record viewing history information together with the broadcast data. Data broadcasting 83 has two Information indicating the conditions for generating the dimension code is included in the two-dimensional code source data 87, and this data is sent to the two-dimensional code generation unit 23. The history information recording instruction does not necessarily depend on the broadcast data. For example, if there is a mechanism for automatic accumulation on the receiver side, it can be used. The history information obtained by such a mechanism is, for example, BML reception history information, electronic program table (EPG) data obtained when watching TV, and other history information.

[0064] In this way, the determination instruction in the instruction information is based on the viewing history of the viewer rather than generating a two-dimensional code by one viewing of the data broadcast in the receiver 20. Generate a two-dimensional code when matches a certain condition. Therefore, when the receiver 20 views a predetermined broadcast (here, the first episode, the second episode, and the third episode such as a drama or CM) through data broadcasting 81, 82, 83 with different reception times, this history is recorded. Information is sequentially stored in the memory 84. In this example, the two-dimensional code generator 23 obtains from the data broadcast 83 on the condition that a plurality of different broadcast contents (three in this example) constituting one group are all viewed by one receiver. A specific two-dimensional code 88 is generated based on the generated two-dimensional code original data and generation condition information 87.

Note that the two-dimensional code original data and the generation condition information 87 are not necessarily included in the data broadcast 83. It may be received at the stage of data broadcast 81 or data broadcast 82. In that case, for example, an instruction is given that the determination can be made when the specified viewing information is recorded. The condition of viewing history information for generating the two-dimensional code can be stored in advance in the force two-dimensional code generation program included in the two-dimensional code source data 87.

[0066] The generated two-dimensional code is sent to the display unit 25 as display information 88, and together with the other information included in the two-dimensional code original data and the generation condition information 87, as shown in screen example 88a. Is displayed. Whether or not to connect to the network 40 when using the 2D code generated in this example. When connecting to the network 40, URL information is included in the two-dimensional code source data and generation condition information 87, and the information is also incorporated into the two-dimensional code.

FIG. 12 shows a two-dimensional code generation process (3) in the receiver 20 corresponding to the example shown in FIG. It is the represented flowchart.

[0068] First, the received broadcast data is interpreted (S41), and it is checked whether there is a viewing history recording instruction (S42). If not, other processing is performed (S50), and the processing in FIG. 12 is terminated. If there is a viewing history recording instruction, a viewing history recording process is performed (S43). Further, it is checked whether there is a two-dimensional code display instruction (S44). If not, normal two-dimensional code generation processing is executed (S49b). If there is a display instruction based on the viewing history (S45), it is checked whether viewing history data can be acquired in the receiver 20 (S46). If it cannot be obtained, error data is generated and the process is terminated (S48). If viewing history data can be acquired, it is checked whether a two-dimensional code can be generated (S47). If possible, a two-dimensional code is generated based on the two-dimensional code source data and the generation condition information 87 (S49a). If not possible, error data is generated (S48). As described above, when viewing history information accumulated by another mechanism is used, a viewing history recording instruction and a viewing history recording process based thereon are not required. Such history information is, for example, broadcast data, EPG data, other program data history information, etc.

FIG. 13 shows an example of complementing the two-dimensional code original data with reference data. In the example shown in the figure, the two-dimensional code source data and instruction information 62 obtained by the data broadcasting 61 include coupon coupon template information that can be used at the store, and reference data for member I. Including an instruction to generate the final two-dimensional code source data by adding a member number, member name, etc.). The member I blueprint may be input manually by the user when generating the two-dimensional code in the receiver, or may be input from the ID holding unit 93 (FIG. 9) described above. The two-dimensional code generation unit 23 adds the member I good news obtained from the reference data generation unit 24 to the coupon data that is the two-dimensional code original data, thereby adding the two-dimensional code original data. And generate a two-dimensional code based on this. In the display unit 25, for example, as shown on a screen 64a, a display including the two-dimensional code 65 as an image is performed together with other information. The user can capture keywords by photographing the two-dimensional code 65 with the camera unit of the mobile terminal 30. The user can use it by holding it over an external code reader.

[0070] In addition, as a method of using member HD information, it is not possible to complement the two-dimensional code source data The two-dimensional code is generated based on the two-dimensional code source data on the condition that it confirms that the member ID is created according to a predetermined algorithm and that it is a regular member ID. Gore.

FIG. 14 is a flowchart showing a two-dimensional code generation process in receiver 20 corresponding to the example shown in FIG.

First, the received broadcast data is interpreted (S51), and it is checked whether there is two-dimensional code generation instruction information based on complementary data (S52). If not, a normal two-dimensional code generation process is executed (S53). If the display instruction exists, it is checked whether such complementary data can be acquired as reference data in the receiver 20 (S54). If not, error data is generated and the process is terminated (S56). If complementary data can be acquired, it is checked whether a two-dimensional code can be generated based on the complementary data (S55). If possible, a two-dimensional code is generated (S57). If not possible, error data is generated (S56).

[0073] Note that the image size of the receiver is various, and the distance between the viewer and the receiver is also considered various. For this reason, there are cases where the 2D code displayed on the display screen of the receiver cannot be captured in a sufficiently large size. Therefore, in the receiver, the display attributes such as the display size and color of the two-dimensional code are used as reference data using the above-mentioned types, functions, setting information, etc. of the terminal device, especially the data such as the size and type of the display screen. Let's decide

[0074] Further, as shown in FIG. 22, the display of the two-dimensional code specified in the content of the broadcast data is enlarged based on an instruction to the viewer on the receiver side (here, the operator presses the blue button). A function may be provided. Further, the display position and color of the two-dimensional code may be customized by the user.

Next, FIG. 15 shows a system configuration example of the second embodiment of the present invention.

[0076] In the previous embodiment, the receiver generated the two-dimensional code based only on the data broadcast. In this embodiment, taking the bidirectional data broadcast receiver 20a as an example, the receiver generates a two-dimensional code using both broadcast and communication. Therefore, in addition to the configuration of the receiver 20, the receiver 20a communicates with the communication unit 26 (communication unit in FIG. 214). For example, the receiver 20a is connected to the Web server 50 via the network 40 by the communication unit 26, triggered by the viewer's operation on the display result of the content of the data broadcast, and the same two-dimensional code source data and Get instruction information. Therefore, the URL of the Web server 50 is included in the content information. If this URL is fixed, it may be set in the receiver in advance instead of obtaining it from the broadcast. The configuration and operation of the portable terminal 30 are the same as in the above embodiment.

An example of using the system shown in FIG. 15 will be described with reference to FIG. Here, an example is the generation of a two-dimensional code that functions as a ticket for a user who has viewed the contents of data broadcasting to input to the event venue.

As shown in FIG. 16 (a), when the data broadcast 101 is received and displayed by the broadcast receiving unit 21, the communication unit 26 accesses the server 103 via the network 40 in response to an operation from the user. 2D code original data and instruction information are obtained. The two-dimensional code generator 23 receives the acquired data (communication result) and receives reference data from the reference data generator 24. The reference data here is, for example, I information of the user. The two-dimensional code generation unit 23 generates a two-dimensional code based on the data acquired from the server 103 and the user ro information acquired from the reference data generation unit 24 and sends it to the display unit 25. For example, as shown in screen example 108a, an image of two-dimensional code 109 is displayed together with a predetermined message. The user of the mobile terminal 30 captures the two-dimensional code 109 with the camera unit of the mobile terminal 30.

[0079] After that, when using the two-dimensional code, the user displays the two-dimensional code 109 on the display screen of the terminal 30, as shown in FIG. 16 (b), and is installed at the gate 110 of the event venue, for example. This two-dimensional code is read by a dedicated terminal. The dedicated terminal accesses the server 103, confirms the reservation information, and if it is determined that the user has the right to enter, the admission is permitted (for example, the gate is opened). Note that the example shown in FIG. 16B can also be used in the first embodiment. Further, in the second embodiment, there may be a use form of the two-dimensional code such that the mobile terminal 30 accesses the Web server based on the recognition result of the two-dimensional code.

FIG. 17 shows a system configuration diagram according to the third embodiment of the present invention. This system The system does not use data broadcasting to generate two-dimensional codes. That is, the receiving terminal 200 is obtained from the communication unit 214 connected to the network 40, the reference data generation unit 224 that generates reference data as described above, and the two-dimensional code source data and reference data generation unit 224 obtained from the communication unit. A two-dimensional code generation unit 223 that generates a two-dimensional code based on the reference data, and a display unit 225 that displays the two-dimensional code. The configurations and functions of the two-dimensional code generation unit 223, the reference data generation unit 224, and the display unit 225 are the same as those of the above-described two-dimensional code generation unit 23, reference data generation unit 24, and display unit 25.

In this embodiment, the receiving terminal 200 acquires content information described in a markup language such as HTML, for example, from a certain web server 50a, and corresponds to reference data based on this content information. Generate a two-dimensional code. Other points are the same as in the above-described embodiment. That is, the user of the mobile terminal 30 captures the two-dimensional code displayed on the display unit 225 of the receiving terminal 200 with the camera unit 35, displays the result, or based on the URL recognized by the two-dimensional code recognition unit 33. The Web server 50b (which may be the same as the Web server 50a) can be accessed via the communication unit 31 and the network 40.

FIG. 18 shows a schematic configuration example of the receiving terminal 200 shown in FIG. The receiving terminal 200 includes a CPU 201, a ROM 202, an input unit 203, a clock unit 207, a RAM 211, a display unit 212, and an audio output unit 213.

The CPU 201 is a control unit that controls the operation of the entire receiving terminal 200 by program control, and is connected to each unit via a bus 208. The ROM 202 is a read-only nonvolatile memory that stores various programs executed by the CPU 201 and fixed data such as font data. In this example, HTML interpretation / display program, 2D code generation program, etc. are stored. On the other hand, the RAM 211 is a readable / writable memory that provides a temporary data holding area, a data work area, and the like used by the CPU 201. In this example, user postal code data, which is personal information as an example of reference data in the present invention, user viewing history data, received HTML document data, and the like are stored. Among these data, at least necessary data is preferably stored in an area backed up by a battery, and is retained even when the receiving terminal 200 is powered off. Instead of RO At least part of the M202 is equipped with rewritable non-volatile memory such as flash memory, where reference data can be stored.

[0084] The input unit 203 includes devices such as a keyboard and a mouse for the user to input instructions and information. A clock unit 207 is a part that outputs information on the current date and day of the week. The display unit 212 is a display device having a display screen that presents visible information to the user, and the type thereof is arbitrary, such as a CRT, a liquid crystal display, a plasma display, and an organic EL display. The audio output unit 213 is a part that outputs an audio signal such as a speaker as audio. In addition, an ID reader 209 as described above may be provided which is used in some aspects of the present invention.

FIGS. 19 (a) and 19 (b) respectively show a conventional display screen example of the receiving terminal 200 and a first example of the present invention.

An example of a display screen according to the third embodiment is shown. Fig. 19 (a) shows an example of the content screen displayed by the browser of the receiving terminal 200. In the figure, links (anchor points) 121, 122, 123 are set in the underlined parts. It is shown that. In this embodiment, as shown in FIG. 19B, two-dimensional codes 131, 132, 133 corresponding to each link are generated and displayed on such a screen as shown in FIG. 19 (b). The Even in this embodiment, if reference data exists, a different two-dimensional code can be generated accordingly. Also, some links may not use reference data. Further, at the link location where the use of the reference data is assumed, if there is no valid reference data as described above, a fixed two-dimensional code not depending on the reference data is displayed.

[0086] When the user of the mobile terminal 30 captures any two-dimensional code, the mobile terminal 30 can access the URL set by the two-dimensional code.

FIGS. 20 (a) and 20 (b) are screen examples showing modifications of FIG. 19 (b). In FIG. 20 (c), the display area of the two-dimensional code is displayed in a dedicated area 135 separated from other normal content information on the browser screen. For example, the size of the display screen is used as the reference data, and when this size is a predetermined size or larger, the two-dimensional code is displayed in such a display mode. Thereby, it becomes easy to photograph the two-dimensional code when photographing the two-dimensional code.

[0088] FIG. 20 (b) is a two-dimensional view corresponding to the link location 136 focused on the browser screen. In this example, only the code (132 in this example) is displayed. Event information indicating that focus has been obtained is used as reference data, and the corresponding link destination information is converted into a two-dimensional code accordingly. The display of the 2D code is deleted at the link location out of focus. As a result, since the two-dimensional code can be displayed only for the link location that the user is interested in, it is not possible to photograph another two-dimensional code by mistake. Moreover, even when the number of two-dimensional codes increases, the force that the display area is filled with two-dimensional codes can be avoided.

It should be noted that the user may be able to set so that when a link location is detected, all the two-dimensional codes are displayed. In this case, such an instruction is set not on the Web data side but on the receiving terminal side.

FIGS. 21 (a) and 21 (b) show various modes of the receiver 20 and the receiving terminal 200, respectively. That is, as shown in FIG. 21 (a), the receiver 20 takes various forms such as a receiver 20a installed at a station or a street, a receiver 20b installed at a store, an in-vehicle receiver 20c, etc. The In addition, as shown in FIG. 21 (b), the receiving terminal 200 similarly has various forms such as a receiving terminal 200a installed at a station or street, a receiving terminal 200b installed at a storefront, and an in-vehicle receiving terminal 200c. Possible.

[0091] As described above, the force described for the preferred embodiment of the present invention Various modifications and changes other than those mentioned above can be made.

[0092] For example, an example in which a two-dimensional code photographed by the mobile terminal 30 is displayed on the display screen has been shown. However, in a case where a Web server is accessed based on the photographed two-dimensional code, the two-dimensional code is not necessarily displayed. Need not be displayed on the display screen of the mobile terminal 30. Although an example is shown in which the broadcast is received by radio waves, it may be received via a wire such as a cable. It can also be in the form of live internet broadcasts.
