FIG. 8 shows a format of a payload (watermark payload) 9 of watermark data included in the watermarked broadcast audio.
The watermark payload 9 includes broadcast content identification information (content identification information such as a content ID) 91 and a broadcast time 92 of the content. The content ID 91 and the broadcast time 92 correspond to the content ID 61 and the broadcast time 62 of the watermark data table 6, respectively.

2. Action

FIG. 9 is a link table acquisition sequence.
First, reference data 82 is set in advance for the content ID 81 and the additional information 84 in the link table 8 of the link server 4 (S101). The link table 8 may be set by a maintenance person or the like, or may be set in advance by default or the like.
When an application is activated in the terminal 3 by an operation by the user or automatically at a predetermined timing / period, etc. (S102), the processing unit 31 requests the link server 4 to acquire an information on the link table 8 Is transmitted (S103). When the link server 4 receives the information acquisition request for the link table 8 from the terminal 3 (S104), the processing unit 42 creates a response including the information of the link table 8 in the link server storage unit 43 and sends it to the terminal 3 (S105). When the terminal 3 receives a response including the information of the link table 8 from the link server 4, the processing unit 31 stores the information in the link table 7 in the storage unit 34 (S107). The link server 4 may automatically transmit the information of the link table 8 to the terminal 3 at a predetermined timing, period, or time without request from the terminal 3.

FIG. 10 is a flowchart of information display processing by the terminal 3.
When the processing is started in the terminal 3, the processing unit 31 receives the broadcast audio with watermark from the receiver / recording / reproducing device 2 by the audio IF unit 33 (S201). The processing unit 31 detects watermark data from the received broadcast audio, and stores the content ID 91 and the broadcast time 92 included in the watermark payload 9 in the content ID 61 and the broadcast time 62 of the watermark data table 6 in the storage unit 34, respectively. To do. Further, the processing unit 31 obtains the detection time (or sound collection time) of the watermarked broadcast audio by the internal clock 32 and stores the obtained time in the detection time 63 of the watermark data table 6 (S203). The processing unit 31 can repeatedly execute the processes in steps S201 and S203 at regular time intervals or when detecting a predetermined timing / period / time and a watermark payload 9 that are set in advance.
The processing unit 31 acquires additional information (position information and / or registration information) from the additional information unit 38 (S213).
The processing unit 31 refers to the watermark data table 6 and determines whether the difference between the detection time 63 and the broadcast time 62 is equal to or less than a predetermined value (for example, T _th ). When the difference is larger than _Tth (S205, No), the processing unit 31 performs the process A (S207). On the other hand, when the difference is equal to or less than _Tth (S205, Yes), the processing unit 31 performs the process B (S209).
If the processing unit 31 performs the processing A or the processing B and then finishes receiving the watermarked broadcast sound (S211, Yes), the processing ends. On the other hand, when the reception of the watermarked broadcast sound is not completed (S211, No), the process returns to step S201.

Hereinafter, processing A and processing B will be described. The viewing mode determined as the process A is assumed to be time-shifted viewing, for example, and the viewing mode determined as the processing B is assumed to be real-time viewing, for example.

As “Processing A”, for example, the processing unit 31 does nothing. In addition, as the “process A”, the processing unit 31 may execute one or more of the following processes, for example.
-Display of pages such as time-shifted viewing URLs that are preset or arbitrarily preset based on the content ID and / or additional information (Note that each URL page is a broadcast station, time zone, date, (It can be set as appropriate depending on one or more places.)
(When the reference data is a URL or the like) Refer to the link table 7 in the terminal 3 and display / guide the page of the URL or the like corresponding to the content ID and / or additional information held therein (the reference data is a command) Or in the case of application identification information, etc.) Referencing the link table 7 in the terminal 3 and starting another application by a command or the like corresponding to the content ID and additional information held therein-based on the content ID and / or additional information Access a predetermined server set in advance or arbitrarily, or start an application on the server (in addition, each command is one of broadcasting station, time zone, date and time, location, etc. It can be set appropriately depending on the number.)
-Change of the point value such as the score held in the terminal 3 that is preset or arbitrarily preset based on the content ID and / or additional information-It is preset based on the content ID and / or additional information Or change the state, parameters, etc. in the processing in the terminal 3 etc., which is arbitrarily set in advance

As the “process B”, for example, the processing unit 31 can execute one or more of the following processes different from the “process A”.
(When the reference data is a URL or the like) Refer to the link table 7 in the terminal 3 and display / guide a page such as a URL corresponding to the content ID and additional information held there. Content ID and / or additional information Display of pages such as URLs for real-time viewing that have been set in advance or arbitrarily set based on the URL (Note that pages such as URLs are appropriately set according to one or more of the broadcasting station, time zone, date and time, place, etc. can do.)
(When the reference data is a command or application identification information or the like) The link table 7 in the terminal 3 is referred to, and another application is activated by a command or the like corresponding to the content ID and additional information held therein. Access to a predetermined server set in advance or arbitrarily set based on additional information, or start an application in the server (in addition, each command is broadcast station, time zone, date and time, It can be set as appropriate depending on the location.)
-Change of the point value such as the score held in the terminal 3 that is preset or arbitrarily preset based on the content ID and / or additional information-It is preset based on the content ID and / or additional information Or change the state, parameters, etc. in the processing in the terminal 3 etc., which is arbitrarily set in advance

Here, the position of step S213 is not provided at the position shown in the figure, and when additional information is used only in process A, it is provided between step S205 and step S207, while when additional information is used only in process B. Alternatively, it may be provided between step S205 and step S209.

The processing unit 31 stores one or a plurality of content IDs and / or reference data as a log in the storage unit 34 when information is displayed by reference data or specific processing is performed. Send the log to a predetermined log collection server at a preset timing, period or time, store the log in the storage unit of the log collection server, and display it on the display unit or output it to the output unit Also good.
The processing unit 31 may display the content ID and / or reference data on the display unit 36 or output the content ID and / or reference data to an appropriate output unit.
Times such as broadcast time and detection time may be dates.

3. Examples of Operation Using Additional Information Each example of “Example 1: Using position information as additional information” and “Example 2: Using registered information as additional information” will be described in detail.

(1) Example 1: Using position information as additional information FIG. 15 is an explanatory diagram of the link tables 7a and 8a using position information.
The link tables 7a and 8a store reference data 72 and 82 for the content IDs 71 and 81 and the position information 74a and 84a. The position information 74a and 84a may indicate an area, for example. When the content ID is “ID1” and the position information is “C”, the processing unit 31 refers to the link table 7a, obtains “URL1” as reference data using “ID1” and “C”, and sets “URL1”. to access. On the other hand, if the position ID is “D” even if the content ID is “ID1”, the processing unit 31 obtains “URL2” as reference data by using “ID1” and “D”, and accesses “URL2”. To do.
Next, the position determination by the processing unit 31 of the terminal 3 will be supplementarily described below.
FIG. 16 is an explanatory diagram (1) for position determination.
This figure shows a case where the position (area) C and the position (area) D do not overlap, for example.
On the other hand, FIG. 17 is explanatory drawing (2) about position determination.
This figure shows a case where the position (area) C includes the position (area) D, for example.
FIG. 18 is an explanatory diagram of a position priority table. In the case of FIG. 17, the priority is determined in advance by the position priority table 101, such as giving priority to the wide area (C> D). When obtaining the position information in step S213, the processing unit 31 refers to the position priority table 101 when the position corresponds to a plurality of positions (areas) such as “position C” and “position D”. A position (here, “position C”) is obtained, and this position information can be used for subsequent processing.
According to the present embodiment, when content suitable for a local area is broadcast by nationwide network broadcasting, information according to the position of the user can be presented.

(2) Example 2: Using Registration Information as Additional Information FIG. 19 is an explanatory diagram of the link tables 7b and 8b using registration information. In the link tables 7b and 8b, reference data 72 and 82 are stored for the content IDs 71 and 81 and the registration information 74b and 84b. Registered information includes, for example, personal information such as the user's gender, age, and age, address, school information such as school / school address / year, work information such as occupation / place of work / work address / position, hobby / preference / access, etc. Appropriate information such as a profile of data can be used. A plurality of registration information can be registered. The processing unit 31 refers to the link table 7b. When the content ID is “ID1” and the registration information is “wine”, the processing unit 31 obtains “URL1” as reference data using “ID1” and “wine”, and accesses “URL1”. To do. Thus, for example, information about a wine store can be acquired. On the other hand, even if the content ID is “ID1”, if the registration information is “Sake”, “URL2” is obtained as reference data by “ID1” and “Sake”, and “URL2” is accessed. Thus, for example, information on a Japanese liquor store can be acquired.
FIG. 20 is an explanatory diagram of a registration priority table. When a plurality of pieces of registration information are registered, the priority is determined in advance by the registration priority table 111. When a plurality of pieces of registration information such as “wine” and “male” are registered at the time of obtaining registration information in step S213, the processing unit 31 refers to the registration priority table 111 to obtain one piece of registration information (here Then, “wine”) can be obtained and this registration information can be used for the subsequent processing.
According to the present embodiment, it is possible to provide information according to user input data (registration data) such as characteristics, hobbies, and preferences.

The registration information can include a plurality of items. In this case, the processing unit 31 selects, for example, reference data of records that match a predetermined number or more items in a preset priority order. Alternatively, the reference data can be obtained as appropriate by selecting the reference data of the record having many matching items among the plurality of items.
Further, both position information and registration information may be used as additional information.

B. Second embodiment

FIG. 11 is an explanatory diagram of the watermark data table.
The watermark data table 6 ′ uses an embedding time 62 ′ in which the watermark data is embedded or embedded by a preset rule / procedure or the like instead of the broadcast time 62 of the watermark data table 6 shown in FIG. It is.
Thus, in the first embodiment, instead of the broadcast time 92, the time (embedding time) 62 ′ at which the watermark data is embedded may be used.

FIG. 12 is a configuration diagram of the regenerator 2a.
In the first embodiment, for example, the broadcasting station 1 broadcasts content that has been created in advance with watermark data. On the other hand, the reproduction of the broadcast audio with watermark data is not the combination of the broadcast station 1 and the receiver / recording / reproducing device 2, but the content with watermark data is carried into the reproducing device 2a as shown in FIG. A recording signal of the playback content may be played back by 2a1. At this time, the watermark data table may use the broadcast time 62 as shown in FIG. 6, or may instead use the embedded time 62 ′ as shown in FIG. 11.

C. Third embodiment

FIG. 13 is a flowchart of information display processing by the terminal 3.
The information display process flowchart of FIG. 10 may be connected in multiple stages as shown in FIG. 13 for the condition determination in step S205, and may be branched to process C, process D,.
As a specific example, for example, the broadcast time 62 is set as the watermark embedding time, and it is determined that the same day is calculated by calculating the difference between the detection time 63 and the broadcast time 62 in the terminal 3 in the broadcast by in-store broadcasting or the like. When, or when it is determined to be the next day or the day after next, the page of reference data such as a URL displayed in each can be changed.
Each process of process C, process D... Is one of the process items described above for “process A” or “process B”, and each process A, B, C, D,. Can be different processing items. It should be noted that the number of stages of multistage processing can be determined as appropriate. Further, the values T _th , T _th −a, T _th −b,... In FIG. It may be possible to rewrite.
The third embodiment can be combined with the first embodiment or the second embodiment.

D. Fourth embodiment

FIG. 14 is an explanatory diagram of the link table.
As shown in the figure, the link tables 7 ′ and 8 ′ include content IDs 71 ′ and 81 ′ and additional information 74 ′.
84 ′ and reference data 72 ′ and 82 ′, further includes identification information (processing identification information such as a processing ID) 73 ′ and 83 ′.
The processing unit 31 refers to the link table 7 ′ in steps 207, 207-1, 207-2, and 209 in FIGS. 10 and 13, and refers to the content ID 71 ′, additional information 74 ′, and each processing 73 ′. Accordingly, reference data 72 ′ is obtained, and display or specific processing using the reference data is executed.
The fourth embodiment can be combined with the first embodiment or the second embodiment. Furthermore, it may be combined with the third embodiment.

E. Effects of the embodiment

According to the present embodiment, since the terminal acquires and accumulates the link table when the application is started or at an appropriate timing, period, time, etc., even if there are a large number of terminals, the link server is different for each terminal. The link data included in the link table can be transmitted at the timing / period. The terminal can execute the information display processing flowchart independently of the link server by using the link table storing the received link data. Thereby, for example, the load of the link server can be reduced or distributed as compared with the case where the terminal accesses the link server at the timing of simultaneous broadcasting such as broadcasting and the link server executes the information display processing. it can.

When the present invention or the present embodiment is used for “in-store broadcasting”, for example, a watermark including a content ID is encoded in an in-store broadcast sound of a hamburger shop or the like that operates a nationwide chain, and the store visitor owns it. The terminal can be used to decode the watermark included in the broadcast audio and be guided to a specific site that issues an electronic coupon.
At this time, it is assumed that access to the server is concentrated immediately after the start of the service, immediately before the end, or at a specific time on a holiday, and a huge load may be applied. Even in such a case, if the present invention or the present embodiment is utilized, it is possible to avoid an increase in load by distributing different servers by selecting different URLs for each store visitor attribute or store area. . The distribution of reference data such as URLs may be performed randomly, or may be performed based on the attributes and regions of the customers.
Further, when the present invention or the present embodiment is used for “outdoor broadcasting”, a special effect is exhibited.
For example, in each shopping street in Shibuya and Shinjuku, audio of watermark-encoded music is played, and visitors to the city are guided to a specific site that introduces the event using their own smartphone. Cases are assumed. Although access to the server may be concentrated from all towns, the load on the server can be reduced in the same manner as “in-store broadcasting”.
In addition, it is possible to encode the “watermarks that differ from city to city” into audio such as music, and be guided to “sites that differ from city to city”. However, when watermarks differ by the number of cities are required, management becomes extremely complicated. Is assumed.
