Description

Embodiments of the present invention relate to an information display program, a TV receiver, and an information display system.

Conventionally, circular boards have been used as a means of sharing local information. Conventional circulation boards require handing over between the people who circulate them, which creates a hassle for the people involved in the circulation. In addition, when handing over a circular board, there is a problem in that the person on the delivery side and the person on the receiving side need to come into physical contact. The problem is that it may pose a security risk.

In recent years, electronic circulation boards using user terminals such as personal computers, tablet PCs, and smartphones have been devised. However, there are problems in that elderly people and the like may not be accustomed to electronic devices such as PCs, tablet PCs, and smartphones as user terminals, and individual differences may occur in the viewing environment. Furthermore, even if conventional circular boards are replaced with electronic circular boards operated by user terminals, information suitable for each person is not selectively provided, and information that is unnecessary for individual viewers may also be displayed on the circular board. There is also the problem that it is provided as information.

It may also be a facility for outputting. In this embodiment, the transmission equipment 18 transmits a broadcast signal containing distribution information supplied from the distribution management server 17 as a broadcast signal of a specific channel.

Next, the configuration of the TV receiver 11 according to the embodiment will be explained.
FIG. 2 is a block diagram showing a configuration example of a control system in the TV receiver 11 according to the embodiment.
In the configuration example shown in FIG. 2, the TV receiver 11 includes a processor (second processor) 31, ROM 32, RAM 33, data memory 34, reception processing section 35, display device 36, speaker 37, communication section 38, remote control interface ( IF) 39, interfaces 41, 42, etc.

The processor 31 executes various processes by executing programs. The processor 31 is, for example, a CPU (Central Processing Unit). The processor 31 is connected to each section within the TV receiver 11 via a system bus, and transmits and receives data to and from each section. The processor 31 cooperates with the ROM 32 and the RAM 33 to execute operations such as data processing and control of various parts in the TV receiver 11. That is, the processor 31 implements the processing functions described below by executing an application program stored in the ROM 32 or the data memory 34. However, some or all of the various functions executed by the processor 31, which will be described later, may be realized by a hardware circuit.

The ROM (Read Only Memory) 32 is a nonvolatile memory that stores programs, control data, etc. for realizing the basic operations of the TV receiver 11. For example, the ROM 32 stores programs that control basic operations such as an operating system (OS). Further, the ROM 32 may store application programs and the like for realizing the functions provided by the TV receiver 11. The ROM 32 may be composed of a rewritable nonvolatile memory. For example, the rewritable ROM 32 is implemented by EEPROM (registered trademark) (Electrically Erasable Programmable ROM), flash ROM, or the like.

The data memory 34 is a storage unit that stores various data. The data memory 34 is composed of a nonvolatile memory in which data can be rewritten. For example, the data memory 34 is a semiconductor device memory such as a flash ROM, an SSD (Solid State Drive), or a storage device such as an HDD (Hard Disc Drive). The data memory 34 stores application programs, operation setting values, and the like for implementing processes to be described later. Further, the data memory 34 may store an OS program.

Furthermore, in this embodiment, the data memory 34 is provided with a storage section (distribution information storage section) that stores distribution information, which will be described later. Further, the data memory 34 may include a storage unit (viewer information storage unit) that stores personal information acquired from the personal identification device 16 as viewer information.

The reception processing unit 35 includes a processing circuit that processes the broadcast signal received by the reception equipment 12. The reception processing unit 35 extracts a video signal, an audio signal, a data signal, etc. from the broadcast signal received by the reception equipment 12. For example, when the reception equipment 12 is an antenna, the reception processing unit 35 includes a tuner, a demodulation circuit, a video decoder, an audio decoder, a data processing circuit, an image processing circuit, an audio processing circuit, and the like. With these configurations, the reception processing unit 35 performs video display and audio output based on the broadcast signal received via the reception equipment 12, and acquires data such as distribution information included in the broadcast signal. The reception processing unit 35 also has a function of displaying information instructed by the processor 31 on the display device 36 and outputting it as sound from the speaker 37.

The reception processing unit 35 receives a broadcast signal for normal television broadcasting and a broadcast signal for data distribution such as distribution information via the reception equipment 12. For example, the reception processing unit 35 demodulates the acquired broadcast wave and separates the video information and audio signal included in the broadcast signal for television broadcasting from the data included in the broadcast signal for data distribution. The reception processing unit 35 causes the display device 36 to display the video obtained by decoding the video signal extracted from the broadcast signal using the video decoder and processing the video using the image processing circuit. Further, the reception processing unit 35 causes the audio processing circuit to process the audio obtained by decoding the audio signal extracted from the broadcast signal using the audio decoder, and then outputs the audio from the speaker 37. The reception processing unit 35 processes distribution information including a distribution information list extracted from the broadcast signal using a data processing circuit, and then supplies the distribution information to the processor 31 and the like.

The display device 36 is a display device such as a liquid crystal panel or an organic EL display. The display device 36 displays a video based on the video signal extracted from the broadcast wave received by the reception processing unit 35. Further, the display device 36 may display images supplied from the processor 31. The speaker 37 outputs audio. The reception processing unit 35 outputs sound based on the audio signal extracted from the received broadcast wave. Further, the speaker 37 may output a sound instructed by the processor 31.

The remote control 40 includes operation keys configured with button switches, a touch sensor that detects the touch of an operator's finger based on a change in capacitance, and the like. For example, with the remote control 40, the user selects a channel to be displayed on the display device 36.

A CAS 14 attached to a predetermined position of the TV receiver 11 is connected to the interface 41 . In the CAS 14 connected to the interface 41 of the processor 31, unique identification information (CAS identification information) such as a management number is recorded. The processor 31 reads the identification information recorded in the CAS 14 via the interface 41. Further, the processor 31 may store personal information acquired from the personal identification device 16 in the CAS 14 as viewer information. In this case, the CAS 14 functions as a storage unit that stores viewer information (viewer information storage unit).

A reader/writer (RW) 15 is connected to the interface 42 . The reader/writer (RW) 15 is a device for communicating with the personal identification device 16. Processor 31 communicates with personal identification device 16 via interface 42 and reader/writer 15 . Note that the reader/writer (RW) 15 may be provided inside the TV receiver 11 or may be an external device.

The reader/writer (RW) 15 only needs to be compatible with the interface included in the personal identification device 16. For example, if the personal identification device 16 is an IC card, the reader/writer 15 is an IC card reader/writer. Further, if the personal identification device 16 is a mobile terminal (for example, a smartphone, a mobile phone, a tablet PC, etc.) equipped with a short-range wireless communication function (for example, Bluetooth (registered trademark), etc.), the reader/writer (RW) 15 This is realized by a communication interface of a communication method such as a short-range wireless communication function provided in a mobile terminal as the personal identification device 16.

Next, the configuration of the personal identification device (personal identification card) 16 carried by a person who is a viewer of the TV receiver 11 according to the embodiment will be described.
FIG. 3 is a block diagram showing a configuration example of a personal identification card (IC card) that is an example of the personal identification device 16 presented to the TV receiver 11 according to the embodiment.
The personal identification device 16 according to the embodiment authenticates the person by comparing authentication information such as biometric information acquired from a person with the authentication information of the registrant (user) registered in advance in the memory within the personal identification device 16. It may be equipped with a function to perform the following.

FIG. 3 shows a configuration example of an IC card as an example of the personal identification device 16. An IC card (hereinafter referred to as a personal identification card) as a personal identification device 16 as shown in FIG. 3 is activated (operated) by electric power supplied from an external device (in the example shown in FIG. It is a portable electronic device.

The personal identification card 16 is an IC card also called a smart card. As shown in FIG. 3, the personal identification card 16 has a main body C. As shown in FIG. The main body C is formed into a card shape from plastic or the like. A control module M is embedded within the main body C of the personal identification card 16. The control module M is integrally formed with a communication interface connected to one or more IC chips.

In the configuration example shown in FIG. 3, the control module M includes a processor 51, a ROM 52, a RAM 53, a data memory 54, and a communication section 55.

Processor 51 includes circuits that perform various processes. The processor 51 is, for example, a CPU (Central Processing Unit). Processor 51 is in charge of overall control of personal identification card 16 . The processor 51 implements various processing functions by executing programs stored in the ROM 52 or data memory 54. However, some or all of the various functions executed by the processor 51 may be realized by a hardware circuit.

The ROM 52 is a nonvolatile memory that functions as a program memory. The ROM 52 stores control programs, control data, and the like in advance. The ROM 52 is incorporated into the personal identification card 16 in a state in which control programs, control data, etc. are stored at the manufacturing stage. The control program and control data stored in the ROM 52 are incorporated in advance according to the specifications of the personal identification card 16. For example, the ROM 52 stores a program for the processor 51 to execute processing in response to commands received from an external device (card reader/writer).

The RAM 53 is a volatile memory that functions as a working memory. The RAM 53 also functions as a buffer that temporarily stores data being processed by the processor 51. For example, the RAM 53 functions as a communication buffer that temporarily stores data transmitted and received with an external device via the communication unit 55.

The data memory 54 is a nonvolatile memory in which data can be written and rewritten. The data memory 54 is configured with, for example, an EEPROM (Electrically Erasable Programmable Read Only Memory). Programs and various data corresponding to the usage of the IC card 16 are written into the data memory 54 . Program files, data files, etc. are defined in the data memory 54, and control programs and various data are written into these files.

Further, a part or all of the area of the data memory 54 has tamper resistance, so that data can be stored securely. For example, the data memory 54 stores biometric information (authentication information) of the user who is the owner of the personal identification card 16. When the personal identification card 16 is a fingerprint sensor card that performs fingerprint authentication using a fingerprint, fingerprint information is written in the data memory 54 as authentication information of the user who is the owner.

The communication unit 55 includes a communication control unit and an interface unit, and constitutes a communication unit. The communication unit 55 is an interface for communicating with the reader/writer (RW) 15 included in the TV receiver 11 or the reader/writer 15 connected to the TV receiver 11 via an interface. The communication unit 55 realizes a communication function using a communication method compatible with the interface of the reader/writer 15. For example, the communication unit 55 may be configured to support multiple communication methods (for example, contact communication and non-contact communication).

When the personal identification card 16 is a contactless IC card, the communication unit 55 constitutes a communication unit that communicates with the reader/writer 15 in a contactless (wireless) manner. In this case, the communication unit 55 includes an antenna that transmits and receives radio waves, and is configured with a modulation circuit for generating radio waves to be transmitted from the antenna, a demodulation circuit for generating a signal from the radio waves received by the antenna, and the like.

Further, when the personal identification card 16 is a contact type IC card, the communication section 55 contacts and communicates with the reader/writer 15. In this case, the communication section 55 includes a contact section that makes physical and electrical contact with the contact section provided on the reader/writer 15, and is constituted by a communication control circuit that controls transmission and reception of signals via the contact section. .

Next, the configuration of the distribution management server 17 according to the embodiment will be described.
FIG. 4 is a block diagram showing a configuration example of a control system in the distribution management server 17 of the information display system 1 according to the embodiment.
In the configuration example shown in FIG. 4, the distribution management server (distribution management system) 17 includes a processor (first processor) 61, a ROM 62, a RAM 63, a data memory 64, an information input section 65, an information output section 66, etc. .

The processor 61 executes various processes by executing programs. The processor 61 is, for example, a CPU (Central Processing Unit). The processor 61 is connected to each section in the distribution management server 17 via a system bus, and transmits and receives data to and from each section. The processor 61 cooperates with the ROM 62 and the RAM 63 to execute operations such as data processing and control of various parts in the distribution management server 17. That is, the processor 61 implements the processing functions described below by executing an application program stored in the ROM 62 or the data memory 64. However, some or all of the various functions executed by the processor 61, which will be described later, may be realized by a hardware circuit.

A ROM (Read Only Memory) 62 is a nonvolatile memory that stores programs and control data for realizing the basic operations of the distribution management server 17. For example, the ROM 62 stores programs that control basic operations such as an operating system (OS). Further, the ROM 62 may store application programs and the like for realizing the functions provided by the distribution management server 17. The ROM 62 may be composed of a rewritable nonvolatile memory. For example, the rewritable ROM 62 is implemented by an EEPROM (Electrically Erasable Programmable ROM), a flash ROM, or the like.

RAM (Random Access Memory) 63 is a volatile memory that temporarily stores data. The RAM 63 functions as a working memory when the processor 61 executes a program.

The data memory 64 is a storage unit that stores various data. The data memory 64 is composed of a nonvolatile memory in which data can be rewritten. For example, as the data memory 64, a semiconductor device memory such as an HDD (Hard Disc Drive) or an SSD (Solid State Drive), or a storage device such as a flash ROM is used. The data memory 34 stores distribution information, which will be described later. Furthermore, the data memory 64 stores application programs, operation setting values, and the like for implementing processes to be described later.

The information input unit 65 inputs information from an information sender. For example, the information input unit 65 may be a communication interface connected to the registrant's user terminal via a network, or the operator may input information presented by the registrant by facsimile, telephone, or letter as distribution information. It may be an interface that The information input unit 65 inputs messages and target person information included in the distribution information from an information sender who wishes to distribute the information (messages). Further, the information input unit 65 inputs information sender information (challenge data for registrant information) for authenticating that the information sender is a registrant.

The information output unit 66 outputs distribution information to be distributed to the TV receiver 11 to the transmission equipment 18. The information output section 66 may be of any type as long as it can supply distribution information to the transmission equipment 18. For example, the information output unit 66 may be a communication interface for connecting to the transmission equipment 18 via a network.
Note that the transmission equipment 18 transmits a broadcast signal containing distribution information from the distribution management server 17 as a broadcast signal of a specific channel. The transmitting equipment 18 may transmit a broadcast signal of a specific channel as a radio wave that can be received by the receiving equipment 12, or transmit a broadcast signal of a specific channel that can be received by the receiving equipment 12 via a cable. It may be something. That is, it is assumed that a specific Chanel broadcast signal including distribution information transmitted by the transmitting equipment 18 is received by the receiving equipment 12 connected to the TV receiver 11.

Next, various types of information held by each device of the information display system 1 including the TV receiver 11 according to the embodiment will be explained.
FIG. 5 is a diagram for explaining various types of information held by each device of the information display system 1 including the TV receiver 11 according to the embodiment.
As shown in FIG. 5, the distribution management server 17 maintains a registrant list in a storage device such as the data memory 64, which stores information (registrant information) of registrants who can register distribution information. The registrant information includes authentication information for authenticating whether or not the person is authorized to register the information (messages) to be distributed.

The distribution management server 17 acquires registrant information from an information sender (registration applicant) who requests registration of distribution information to be distributed to the TV receiver 11. When the distribution management server 17 confirms that the information sender is a registrant by referring to the registrant list, the distribution management server 17 acquires notification items and target person information, which serve as distribution information, from the information sender.

Here, the message is information to be displayed on a specific channel on the TV receiver 11. The message is assumed to be, for example, information written on a conventional circular board. Furthermore, the message may be any information that can be displayed or output on the TV receiver 11. That is, the message may be information including not only text information but also audio, images, videos, and the like.

The target person information is information for limiting (specifying) the person to whom the message is to be displayed. For example, the target person information is information for limiting (specifying) a person (viewer) who can view the message based on personal information that can be obtained from the personal identification device 16. For example, the target person information may limit viewers of the message based on address, or may limit people (viewers) who can view the message based on age or gender.

The distribution management server 17 stores messages from registrants who have been successfully confirmed using the registrant list and target person information in a storage device such as the data memory 64 as distribution information. The distribution management server 17 registers distribution information consisting of notifications from registrants and target person information in a distribution information list. The distribution management server 17 outputs a broadcast signal including the distribution information registered in the distribution information list to the TV receiver 11 through the transmission equipment 18.

On the other hand, the TV receiver 11 acquires personal information from the personal identification device 16 presented by the person who is the viewer. In the example shown in FIG. 5, the TV receiver 11 stores personal information acquired from the personal identification device 16 in the CAS 14 as viewer information. In this case, the CAS 14 functions as a storage unit for viewer information. Furthermore, the TV receiver 11 may store viewer information in the data memory 34. In this case, the data memory 34 functions as a storage section for viewer information. Furthermore, the TV receiver 11 may temporarily store the personal information in the RAM 33, or read it from the personal identification device 16 connected to the reader/writer 16 without storing it in the TV receiver 11. It's okay.

The receiving equipment 12 connected to the TV receiver 11 receives the broadcast signal containing the distribution information list transmitted from the distribution management server 17 through the transmitting equipment 18 . The TV receiver 11 acquires the distribution information list from the broadcast signal received by the reception equipment 12. Upon acquiring the distribution information list, the TV receiver 11 compares the target person information and viewer information of each distribution information included in the acquired distribution information list.

When the target person information and the viewer information match, the TV receiver 11 displays on the display device 36 the message corresponding to the target person information that matches the viewer information. In addition, the TV receiver 11 stores distribution information of target person information that matches the registered viewer information in the data memory 34 as a distribution information storage unit, and when instructed to display a specific channel, The notification items of the distribution information stored in the data memory 34 may be displayed on the display device 36.

Next, a process in which the distribution management server 17 registers distribution information to be distributed to the TV receiver 11 according to the embodiment will be described.
FIG. 6 is a flowchart for explaining an operational example of a process in which the distribution management server 17 registers distribution information to be distributed to the TV receiver 11 according to the embodiment.
First, it is assumed that the distribution management server 17 has registered information (registrant information) of a registrant who is permitted to distribute information that can be displayed on the TV receiver 11. A person who can register registrant information (a person who can distribute information) does not need to be limited to a specific person, and may be any person defined by the operational rules of the information display system 1. For example, in the case of distributing local information to people who constitute a community in a certain area, the executive officer disseminating the local information registers registrant information as a registrant.

The distribution management server 17 stores the registrant information in the registrant list of the data memory 64. The registrant information includes information for confirming that the registrant is a registrant. For example, if the registrant is confirmed (authenticated) using authentication information such as a password, the distribution management server 17 registers registrant information including the registrant's identification information and authentication information in the registrant list. . Furthermore, when the target to be distributed is specified in advance, the distribution management server 17 may register target person information indicating the target person to whom the information is to be distributed as the registrant information.

The processor 61 of the distribution management server 17 uses the information input unit 65 to acquire registrant information from a person (information sender) who desires to register distribution information (ST1). The information input unit 65 may be a communication interface that receives registrant information sent from a user terminal operated by an information sender, or may be a communication interface that allows an operator to input registrant information sent by a registrant by facsimile, telephone, etc. It may also be an input device.

For example, when transmitting information from a user terminal operated by the information transmitter himself, the processor 61 of the distribution management server 17 uses an interface serving as the information input unit 65 to acquire registrant information received from the user terminal. Further, when an information sender sends information by facsimile, telephone, etc., the processor 61 of the distribution management server 17 allows the operator to input the registrant information obtained by facsimile, telephone, etc. using an input device as the information input section 65. and obtain the registrant information entered by the operator.

When the processor 61 of the distribution management server 17 obtains registrant information from the information sender through the information input unit 65, it compares the registrant information obtained from the information sender with the registrant information registered in the registrant list. This confirms (authenticates) whether the information sender is a registrant (ST2).

If the processor 61 of the distribution management server 17 cannot confirm that the information sender is a registered registrant (ST3, NO), the processor 61 of the distribution management server 17 determines that it is not possible to accept the distribution information from the information sender. If the processor 61 disallows the reception of the distribution information, the processor 61 notifies (notifies) the information sender that the reception of the distribution information is prohibited, and ends the process (ST4).

When the processor 61 of the distribution management server 17 confirms that the information sender is a registered registrant (ST3, YES), the processor 61 of the distribution management server 17 permits reception of distribution information from the information sender. When the processor 61 permits the reception of the distribution information, the information input unit 65 acquires the message (information to be distributed) transmitted by the information sender (ST5).

The processor 61 of the distribution management server 17 also obtains target person information corresponding to the message from the information sender using the information input unit 65 (ST6). Here, the target person information may include not only conditions for specifying the person to whom the distribution is to be made, but also distribution conditions such as the distribution period, distribution time zone, or distribution area.

Further, the target person information may be set in the registrant information. That is, a registrant as an information sender may register (set) as registrant information that information (notices) will be distributed to a specific target person. If the target person information is registered in the registrant information, the processor 61 of the distribution management server 17 may acquire the target person information from the registrant information registered in the registrant list.

When the processor 61 of the distribution management server 17 acquires the message and the target person information, it stores the acquired message and the target person information in a storage device such as the data memory 64 as distribution information in association with each other (ST7). Further, the processor 61 may add identification information (ID) or the like to the message acquired from the information sender and the target person information corresponding to the message, and store the message as distribution information.

After storing the distribution information received from the information sender, the processor 61 of the distribution management server 17 registers the distribution information in the distribution information list stored in the data memory 64 (ST8). For example, as shown in FIG. 5, the distribution information list stores distribution information consisting of notification items and target person information. Further, the distribution information list may store distribution information for each distribution condition such as distribution period or distribution area.

When the processor 61 of the distribution management server 17 registers the distribution information from the information sender in the distribution list, it assumes that the distribution settings of the distribution information including the notifications acquired from the information sender and the target person information are completed, and starts the distribution. The information sender is notified of the completion of the settings (ST9).

After the processor 61 of the distribution management server 17 completes the distribution settings, the information output unit 66 supplies the distribution information list to the transmission equipment 18 . The transmission equipment 18 distributes a broadcast signal including the distribution information list acquired from the distribution management server 17 to each TV receiver 11.

Next, a display process in which the TV receiver 11 according to the embodiment displays distribution information distributed from the distribution management server 17 will be described.
FIG. 7 is a flowchart for explaining a first operation example of a display process in which the TV receiver 11 according to the embodiment displays distribution information distributed from the distribution management server 17.
In the first operation example shown in FIG. 7, the TV receiver 11 registers personal information acquired from the personal identification card 16 as viewer information, and distributes information ( notification) is displayed on the display device 36.

First, the processor 31 of the TV receiver 11 determines whether or not to perform viewer registration (ST11). For example, when the personal identification device 16 is connected to the reader/writer 15, the processor 31 determines to execute a process of registering personal information read from the personal identification device 16 as viewer information. Furthermore, it is assumed that the processor 31 executes registration of viewer information when viewer registration is instructed using the remote control 40 or the like.
If the processor 31 does not register the viewer information (ST11, NO), the process proceeds to ST14.

When the processor 31 determines to register the viewer information (ST11, YES), the reader/writer 15 reads the personal information from the personal identification device 16 (ST12). For example, when the personal identification device 16 is an IC card for personal identification (personal identification card), the processor 31 accesses the personal identification device 16 using the reader/writer 15 that is an IC card reader/writer, and Obtain personal information from.

Upon acquiring the personal information from the personal identification device 16, the processor 31 registers the personal information acquired from the personal identification device 16 as viewer information (ST13). For example, the processor 31 registers the personal information acquired from the personal identification device 16 in the CAS 14 as viewer information. After the processor 31 registers the personal information from the personal identification device 16 as viewer information, the process proceeds to ST14.

The processor 31 of the TV receiver 11 determines whether a specific channel for displaying distribution information from the distribution management server 17 has been selected (ST14). For example, processor 31 detects that a user uses remote control 40 to select a particular channel for displaying distribution information. Furthermore, when the personal information on the personal identification card 16 is registered as viewer information, the processor 31 may determine that a specific channel has been selected. Furthermore, the processor 31 may determine that a specific channel has been selected when the personal identification card 16 is connected to the reader/writer 15.

If a specific channel is not selected (ST14, NO), the processor 31 of the TV receiver 11 returns to ST11 and performs the above-described processing while continuing to perform normal operations such as displaying broadcasts other than the specific channel. repeat.

When the specific channel is selected (ST14, YES), the processor 31 of the TV receiver 11 receives the broadcast signal including the distribution information from the distribution management server 17 obtained from the receiving equipment 12 as the broadcast signal of the specific channel ( ST15). When the processor 31 receives the broadcast signal of the specific channel, it determines whether the received broadcast signal includes a distribution information list in which distribution information is registered (ST16).

Note that the processor 31 of the TV receiver 11 may store the broadcast signal of a specific channel for a predetermined period of time. In this case, the processor 31 may determine whether the stored broadcast signal includes the distribution information list.

If the received broadcast signal does not include the distribution information list (ST16, NO), the processor 31 causes the display device 36 to display information indicating that there is no distribution information (message) to be displayed (ST20); Return to ST11.

If the received broadcast signal includes a distribution information list (ST16, YES), processor 31 extracts the distribution information list from the broadcast signal of the specific channel. After extracting the distribution information list from the received broadcast signal, the processor 31 compares the target person information and viewer information registered in the extracted distribution information list (ST17).

The processor 31 determines whether there is target person information that matches the viewer information by comparing the target person information and the viewer information (ST18). For example, when the target person's address is specified in the target person information of the distribution information list, the processor 31 specifies that the viewer's address (which may be a part of the address) in the viewer information is specified in the target person information. Determine whether the specified address is included. Further, if the age of the target person is specified in the target person information of the distribution information list, the processor 31 determines whether the age of the viewer in the viewer information matches the age specified in the target person information. do.

That is, when the processor 31 of the TV receiver 11 determines that there is no target person information that matches the viewer information (ST18, NO), the processor 31 of the TV receiver 11 determines that there is no distribution information to be provided (displayed) to the viewer, and displays the information. The display device 36 displays information indicating that there is no delivery information (message) to be delivered (ST20), and the process returns to ST11.

Further, when the processor 31 determines that there is target person information that matches the viewer information (ST18, YES), it determines that there is distribution information that should be provided (displayed) to the viewer, and that there is information that matches the viewer information. The message corresponding to the target person information is displayed on the display device 36 (ST19). Here, the processor 31 may not only display the message on the display device 36, but also output part or all of the message in the form of audio through the speaker 37.

Further, the processor 31 may display notifications as distribution information supplied from the distribution management server 17 on a part of the display screen of the display device 36. For example, the processor 31 may display normal television broadcasts on the display screen of the display device, and may also display notifications as distribution information on a part of the display screen.

As described above, the TV receiver according to the first operation example registers the personal information acquired from the personal identification device as viewer information, and when the display of a specific channel is instructed, the TV receiver is contacted from the broadcast signal of the specific channel. Distribution information including matters and target person information is extracted, and notification items corresponding to target person information that match viewer information are displayed on a display device.

Thereby, the TV receiver can cause the display device to display the message to be provided to the viewer who has registered the personal information of the personal identification device as viewer information when a specific channel is selected. Thereby, by selecting a specific channel, the user can easily view messages addressed to him/her from the information sender on the TV receiver.

Next, a second operation example of a display process in which the TV receiver 11 according to the embodiment displays distribution information distributed from the distribution management server 17 will be described.
FIG. 8 is a flowchart for explaining a second operation example of display processing in which the TV receiver 11 according to the embodiment displays distribution information distributed from the distribution management server 17.
In the second operation example shown in FIG. 8, the TV receiver 11 does not store the personal information acquired from the personal identification card 16 as viewer information, and the TV receiver 11 does not save the personal information acquired from the personal identification card 16 as viewer information. Distribution information (messages) to be provided to the viewer is displayed on the display device 36, with the person indicated by the information as the viewer.

During operation, the processor 31 of the TV receiver 11 detects whether the personal identification device 16 is connected to the reader/writer 15 (ST31). For example, when the personal identification device 16 is an IC card for personal identification (personal identification card), the processor 31 determines whether or not the reader/writer 15, which is an IC card reader/writer, has detected the personal identification device 16. It is determined whether the personal identification device 16 is connected to the personal identification device 16.

If the personal identification device 16 is not connected to the reader/writer 15 (ST31, NO), the processor 31 of the TV receiver 11 continues to perform normal operations such as displaying broadcasts other than the specific channel.

When the personal identification device 16 is connected to the reader/writer 15 (ST31, YES), the processor 31 of the TV receiver 11 reads personal information stored in the personal identification device 16 using the reader/writer 15 (ST32). The processor 31 stores the personal information read from the personal identification device 16 as viewer information in the RAM 33, which is a volatile memory (ST33). However, if the personal identification device 16 is connected to the reader/writer 15 so that the processor 31 of the TV receiver 11 can always read the personal information, the personal information of the personal identification device 16 may not be held in the RAM 33. .

After holding the personal information of the personal identification device 16 in the RAM 33, the processor 31 switches to a specific channel (ST34). When the processor 31 of the TV receiver 11 switches to a specific channel in response to the connection of the personal identification device 16, it receives a broadcast signal containing distribution information from the distribution management server 17 obtained from the reception equipment 12 as a broadcast signal of the specific channel. (ST35).

When the processor 31 receives the broadcast signal of the specific channel, it determines whether the received broadcast signal includes a distribution information list in which distribution information is registered (ST36).
Note that the processor 31 of the TV receiver 11 may store the broadcast signal of a specific channel for a predetermined period of time. In this case, when the personal identification device 16 is connected, the processor 31 may determine whether or not the distribution information list is included in the stored broadcast signal of a specific channel for a predetermined period.

If the broadcast signal of the specific channel does not include the distribution information list (ST36, NO), the processor 31 causes the display device 36 to display information indicating that there is no distribution information (notices) to be displayed (ST40). , return to ST31.

If the broadcast signal of the specific channel includes the distribution information list (ST36, YES), the processor 31 extracts the distribution information list from the broadcast signal of the specific channel. After extracting the distribution information list from the received broadcast signal, the processor 31 compares the target person information and viewer information registered in the extracted distribution information list (ST37).

The processor 31 determines whether there is target person information that matches the viewer information by comparing the target person information and the viewer information (ST38). For example, when the target person's address is specified in the target person information of the distribution information list, the processor 31 specifies that the viewer's address (which may be a part of the address) in the viewer information is specified in the target person information. Determine whether the specified address is included. Further, if the age of the target person is specified in the target person information of the distribution information list, the processor 31 determines whether the age of the viewer in the viewer information matches the age specified in the target person information. do.

If the processor 31 of the TV receiver 11 determines that there is no target person information that matches the viewer information (ST38, NO), it determines that there is no distribution information to be provided (displayed) to the viewer, and The display device 36 displays information indicating that there is no distribution information (message) to be provided (displayed) (ST40), and the process returns to ST31.

Furthermore, if the processor 31 determines that there is no target person information that matches the viewer information (ST38, YES), it determines that there is distribution information that should be provided (displayed) to the viewer, and that the viewer information matches the The display device 36 displays the message corresponding to the target person information (ST39). Here, the processor 31 may not only display the message on the display device 36, but also output part or all of the message in the form of audio through the speaker 37. Further, the processor 31 may display the message on a part of the display screen of the display device 36.

As described above, when the TV receiver according to the second operation example acquires personal information from the personal identification device connected to the reader/writer, the TV receiver receives distribution information including notification items and target person information from the broadcast signal of a specific channel. and displays on the display device the notification items corresponding to the target person information that matches the viewer information.

Thereby, the TV receiver can cause the display device to display the message to be provided to the viewer who has registered the personal information of the personal identification device connected to the reader/writer as viewer information. In this case, by connecting a personal identification device to the reader/writer (for example, by holding a personal identification card over the reader/writer), the user can receive information from the sender of the information displayed on the display device of the TV receiver. You can easily see the messages you want to receive.

Next, a third operation example of a display process in which the TV receiver 11 according to the embodiment displays distribution information distributed from the distribution management server 17 will be described.
FIG. 9 is a flowchart for explaining a third operation example of display processing in which the TV receiver 11 according to the embodiment displays distribution information distributed from the distribution management server 17.
In the third operation example shown in FIG. 9, if the personal information acquired from the personal identification card 16 is registered as viewer information, the TV receiver 11 can identify the specific channel even if a specific channel is not selected. Distribution information (notifications) to be provided to registered viewers is extracted from the broadcast signal of the channel and stored, and the saved notifications are displayed on a display device 36 when a specific channel is selected.

First, the processor 31 of the TV receiver 11 determines whether or not to perform viewer registration (ST51). For example, when the personal identification device 16 is connected to the reader/writer 15, the processor 31 determines to execute a process of registering personal information read from the personal identification device 16 as viewer information. Furthermore, it is assumed that the processor 31 executes registration of viewer information when viewer registration is instructed using the remote control 40 or the like.
If the processor 31 does not register the viewer information (ST51, NO), the process proceeds to ST54.

When the processor 31 determines to register the viewer information (ST51, YES), the reader/writer 15 reads the personal information from the personal identification device 16 (ST52). For example, when the personal identification device 16 is an IC card for personal identification (personal identification card), the processor 31 accesses the personal identification device 16 using the reader/writer 15 that is an IC card reader/writer, and Obtain personal information from.

Upon acquiring the personal information from the personal identification device 16, the processor 31 registers the personal information acquired from the personal identification device 16 as viewer information (ST53). For example, the processor 31 registers the personal information acquired from the personal identification device 16 in the CAS 14 as viewer information. When the processor 31 registers the personal information from the personal identification device 16 as viewer information, it proceeds to ST54.

The processor 31 of the TV receiver 11 receives the broadcast signal including the distribution information from the distribution management server 17 obtained from the reception equipment 12 as the broadcast signal of the specific channel, regardless of the selection of the specific channel (ST54). The processor 31 determines whether new distribution information is included in the received broadcast signal of the specific channel (ST55).

For example, if the broadcast signal includes a distribution information list, the processor 31 determines whether or not there is any distribution information in the distribution information list for which the comparison between viewer information and target person information has not been performed. Determine whether information exists.
If the received broadcast signal does not include new distribution information (ST55, NO), the processor 31 proceeds to ST59.

When the received broadcast signal includes new distribution information (ST55, YES), the processor 31 compares the target audience information and viewer information of the new distribution information extracted from the broadcast signal of the specific channel ( ST56). By comparing the target audience information of the new distribution information and the viewer information, the processor 31 determines whether there is target audience information that matches the viewer information among the target audience information of the newly distributed distribution information. (ST57).

For example, if the target person's address is specified in the target person information of new distribution information, the processor 31 determines whether the viewer's address in the viewer information includes the address specified in the target person information. do. Further, when the age of the target person is specified in the target person information of the new distribution information, the processor 31 determines whether the age of the viewer in the viewer information matches the age specified in the target person information. to decide.
If the target person information of the new distribution information extracted from the broadcast signal of the specific channel and the viewer information do not match (ST57, NO), the processor 31 of the TV receiver 11 proceeds to ST59, which will be described later.

If there is target person information of new distribution information extracted from the broadcast signal of a specific channel that matches the viewer information (ST57, YES), the processor 31 of the TV receiver 11 extracts the target person information that matches the viewer information. Distribution information including notification items corresponding to the target person information is stored in a storage device such as the data memory 34 (ST58).

Here, the processor 31 may store only the notification items corresponding to the target person information that matches the viewer information in a storage device such as the data memory 34. Further, when the viewer information is deleted, the processor 31 deletes the distribution information of the target person information that matches the viewer information from the data memory. Further, the processor 31 may set the period for storing the distribution information of the target person information that matches the viewer information to a predetermined period.

Furthermore, the processor 31 of the TV receiver 11 determines whether a specific channel has been selected (ST59). For example, processor 31 detects that a user uses remote control 40 to select a particular channel for displaying distribution information. Furthermore, when the personal information on the personal identification card 16 is registered as viewer information, the processor 31 may determine that a specific channel has been selected. Furthermore, the processor 31 may determine that a specific channel has been selected when the personal identification card 16 is connected to the reader/writer 15.

If a specific channel is not selected (ST59, NO), the processor 31 of the TV receiver 11 returns to ST51 and performs the above-described processing while continuing to perform normal operations such as displaying broadcasts other than the specific channel. repeat.

If a specific channel is selected (ST59, YES), the processor 31 determines whether there is distribution information to be displayed on the display device 36 (ST60). In the third operation example, the processor 31 stores the distribution information of the target person information (or the notice corresponding to the target person information) that matches the viewer information among the distribution information extracted from the broadcast signal of the specific channel into the data memory. It is saved on 34. Therefore, the processor 31 determines whether there is distribution information to be displayed based on whether distribution information of target person information that matches the viewer information is stored in the data memory 34.

If there is no distribution information to be displayed (ST60, NO), the processor 31 displays information indicating that there is no distribution information (messages) to be displayed on the display device 36 (ST62), and returns to ST51.

In addition, when the processor 31 determines that there is distribution information to be displayed (ST60, YES), the processor 31 causes the display device 36 to display notifications corresponding to the target audience information that matches the viewer information stored in the data memory 34. (ST61). Here, the processor 31 may not only display the message on the display device 36, but also output part or all of the message in the form of audio through the speaker 37. Further, the processor 31 may display the message on a part of the display screen of the display device 36.
