Summary of the Invention

Problems to be Solved by the Invention

[0005] By the way, in improving the habitability of a vehicle, when outputting content in the vehicle, even when a plurality of persons of different ages or a plurality of persons with different access qualifications to a content viewing service are sharing the vehicle, it is an issue to output content in accordance with the wishes of each individual passenger as much as possible while taking into account the viewing age limit and access limit of the content.

[0006] In order to solve the above problems, the present application aims to output content in accordance with the wishes of individual passengers as much as possible while taking into account restrictions on viewing and access to content in a moving body in which a plurality of persons ride together as passengers. And, by extension, it contributes to the development of a sustainable transportation system.

Means for Solving the Problems

[0007] One aspect of the present invention is a content output device including: an output unit that outputs content specified by a passenger of a moving body to a display device mounted on the moving body as target content; an identification unit that identifies each of the passengers seated on each seat of the moving body and acquires identification information related to viewing of content for each of the passengers; and a determination unit that determines whether to permit output of the target content in the output unit based on the identification information and restriction information related to viewing of the target content, the content output device further including a proposal unit that makes a proposal related to output of content to the passengers, the proposal unit making a proposal to the passengers for alternative content to the target content or a countermeasure for permitting output of the target content when the determination unit determines that output of the target content is not permitted. According to another aspect of the present invention, the identification information generated by the identification unit includes information on the seat position of the corresponding passenger in the interior of the moving body, the output unit designating a display device arranged at a position in the interior visible from the seat position of a target user who is the passenger who specified the target content as the target display device to output the target content, the determination unit determining, based on the identification information, whether a restricted person who should restrict viewing of the target content according to the restriction information is included among the passengers seated on seats where the target display device is visible, and when the restricted person is included, not permitting output of the target content to the target display device. According to another aspect of the present invention, the identification information generated by the identification unit includes information on whether the corresponding passenger is in a viewable state where the content can be viewed. The determination unit excludes passengers who are not in the viewable state from the determination targets for whether they are the restricted persons. According to another aspect of the present invention, when the determination unit determines that the output of the target content is not permitted, the proposal unit proposes to the passenger, as the alternative content, content that has the same content as the target content and that a passenger sitting in a seat where the target display device is visible is not subject to viewing restrictions based on the restriction information of the content. According to another aspect of the present invention, when the determination unit determines that the output of the target content is not permitted, the proposal unit proposes to the passenger, as the alternative content, content that belongs to the same category as the target content and that a passenger sitting in a seat where the target display device is visible is not subject to viewing restrictions based on the restriction information of the content. According to another aspect of the present invention, the identification information generated by the identification unit includes service subscription information that is information on the viewing service to which the corresponding passenger subscribes and kinship information that is information on the kinship with other passengers. When the target content is content provided from one viewing service to which the target user subscribes, the determination unit determines whether to permit the output of the target content in the output unit based on each passenger's service subscription information and kinship information. According to another aspect of the present invention, when the target content is content provided from one viewing service to which the target user subscribes, if among the passengers sitting in seats where the target display device is visible, there is a person who does not have a predetermined kinship with the target user based on each passenger's service subscription information and kinship information, the determination unit determines the person who does not have the kinship as a restricted person whose viewing of the target content should be restricted, and does not permit the output of the target content in the output unit. According to another aspect of the present invention, when the determination unit determines that the target content is content provided from a certain viewing service to which the target user subscribes, and among the passengers sitting in seats where the target display device is visible, even if there are persons who do not have the predetermined kinship with the target user, if all of the passengers sitting in seats where the target display device is visible and who do not have the predetermined kinship with the target user subscribe to the certain viewing service, or are persons who have the predetermined kinship with other passengers who subscribe to the certain viewing service, the output of the target content in the output unit is permitted. According to another aspect of the present invention, when the target content is content provided by a certain viewing service and the determination unit determines not to permit the output of the target content based on the service subscription information and the kinship information included in the identification information, if another viewing service different from the certain viewing service provides the same content as the target content, the same content as the target content provided by the other viewing service is proposed to the passengers as the alternative content, on the condition that all of the passengers sitting in seats where the target display device is visible subscribe to the other viewing service or have the predetermined kinship with passengers who subscribe to the other viewing service. According to another aspect of the present invention, when the determination unit does not permit the output of the target content in the output unit, as a proposal for the countermeasure for permitting the output of the target content, it is proposed that the restricted person or the target user move their seats so that the restricted person cannot view the target content. According to another aspect of the present invention, when the determination unit does not permit the output of the target content, and when the movement of the seats of a plurality of passengers is required to permit the output of the target content, as a proposal for the countermeasure for permitting the output of the target content, a proposal for changing the seat arrangement of the passengers in the interior of the moving body is made. According to another aspect of the present invention, when the determination unit determines to permit the output of the target content, if the restricted person is included among the passengers of the moving body, the output unit reduces the output level of the reproduction sound of the target content to less than a predetermined level determined in advance, or outputs the reproduction sound toward the seating position of the target user by means of a directional speaker. Another aspect of the present invention is a content output method executed by a computer of a content output device that outputs content designated by a passenger of a moving body to a display device mounted on the moving body, the content output method including: an output step of outputting the content designated by the passenger of the moving body as target content to the display device; an identification step of identifying each of the passengers seated in each seat of the moving body and acquiring identification information related to content viewing for each of the passengers; and a determination step of determining whether to permit the output of the target content in the output step based on the identification information and restriction information related to viewing of the target content, and further including a proposal step of making a proposal related to the output of content to the passengers, wherein in the proposal step, when it is determined in the determination step that the output of the target content is not permitted, a proposal for alternative content of the target content or a proposal for a countermeasure for permitting the output of the target content is made to the passengers.

Effects of the Invention

[0008] According to the present invention, in a moving body in which a plurality of persons ride together as passengers, it is possible to execute content output in line with the wishes of each individual passenger as much as possible while taking into consideration restrictions on viewing and access to content.

In the example shown in FIG. 1, as examples of the moving body 2, a passenger car 2a with three rows of seats, a passenger car 2b with two rows of seats, and a bus 2c are shown. However, these are just examples, and the moving body 2 can be any vehicle (for example, a shared car, a taxi, a chartered bus, etc.) in which a plurality of persons can ride.

[0011] Further, the moving body 2 is not limited to a vehicle and can be any moving body in which a plurality of persons can ride. Such a moving body may be a land moving body such as a passenger car, a bus, a taxi, a train, etc., a marine moving body such as a ship, a submarine, an aircraft including an eVTOL (Electric Vertical Take-Off and Landing aircraft), an air moving body such as a dirigible, or a space moving body such as a spaceship, an artificial satellite.

[0012] The content output device 1 outputs, for example, content provided by a server device provided outside the moving body 2 or content stored in a storage device provided in the moving body 2 according to the instruction of the passenger P of the moving body 2, inside the moving body 2. In this embodiment, the content refers to any information that a user can view via an audiovisual device, and for example, movies, animations, dramas, games, etc.

[0013] As an example of a server device that provides content, FIG. 1 shows a first content server 4a, a second content server 4b, and a game server 5. The content output device 1 is communicably connected to the first content server 4a, the second content server 4b, and the game server 5 via a communication network 3.

[0014] The first content server 4a and the second content server 4b are each used for different content viewing services (hereinafter referred to as "viewing services") provided by different content providing companies. For example, the viewing service can be Netflix, Amazon Prime, Hulu, etc. Hereinafter, the first content server 4a and the second content server 4b are also collectively referred to as the content server 4.

[0015] In the present embodiment, for example, the content provided by each of the first content server 4a and the second content server 4b can be viewed by the user by previously obtaining an account for the corresponding viewing service and subscribing to the viewing service.

[0016] The game server 5 is a server device that provides game content (hereinafter also referred to as game content), and is operated by, for example, a company that provides a game content providing service. For example, the user can enjoy an online game by accessing the game server 5. In the present embodiment, the use of the game content provided by the game server 5 (playing the game) becomes possible when the user previously obtains an account for the corresponding game providing service and subscribes to the game providing service. In the present embodiment, viewing of content includes use of game content. In the use of game content, the user views the video and sound of the game content.

[0017] In this embodiment, it is assumed that the content provided by the first content server 4a and the second content server 4b is prohibited from being viewed by persons other than the user who has acquired the account (hereinafter also referred to as the account user) and his / her family in the regulations of the corresponding viewing service. Also, the first content server 4a, the second content server 4b, and the game server 5 provide restriction information which is information about the restrictions related to viewing for the content they provide. The restriction information includes information about viewing restrictions set for each content, such as age restrictions which are restrictions on the age of the users who can view, for example. The restriction information may also include information about viewing restrictions according to the viewing service regulations, such as information prohibiting viewing by persons other than the account user and his / her family.

[0018] Note that the content output device 1 may communicate via the communication network 3 with content servers and game servers (both not shown) that can be used without acquiring an account, and output the content provided by those server devices inside the mobile body 2. The number of content servers and / or game servers connected to the communication network 3 and available for use by the content output device 1 is arbitrary.

[0019] The content output device 1 may also read the content from a storage device and / or a reading device for a storage medium provided in the mobile body 2 and output it inside the mobile body 2.

[0020] [1.2 Configuration of the Mobile Body] Next, the configuration of the mobile body 2 on which the content output device 1 is mounted will be described. FIG. 2 is a diagram showing an example of the configuration of the mobile body 2. In FIG. 2, as an example, the configuration of the mobile body 2a with three rows of seats is shown, but other mobile bodies 2b and 2c may be configured similarly.

[0021] In the cabin 10 where the passenger P of the moving body 2 is seated, there are arranged a driver's seat 12a where the driver who operates the steering wheel 11 is seated, a passenger seat 12b, a left seat 12c in the second row, a right seat 12d in the second row, a left seat 12e in the third row, and a right seat 12f in the third row. Hereinafter, the driver's seat 12a, the passenger seat 12b, the left seat 12c in the second row, the right seat 12d in the second row, the left seat 12e in the third row, and the right seat 12f in the third row are also collectively referred to as the seat 12.

[0022] At a position in front of the driver's seat 12a on the instrument panel (not shown) of the moving body 2, a display device 13a that can be visually recognized by the driver who is the passenger P seated in the driver's seat 12a is arranged.

[0024] Also, at the center of the instrument panel of the moving body 2, a display device 13g which is a central display device that can be visually recognized by all the passengers P seated in any seat 12 is arranged. Hereinafter, the display devices 13a, 13b, 13c, 13d, 13e, 13f, and 13g are also collectively referred to as the display device 13. In the present embodiment, the display device 13 is a touch panel. However, the display device 13 is not limited to a touch panel and can be any type of display device. Further, the display devices 13a, 13b, 13c, 13d, 13e, 13f, and 13g do not all have to be of the same type of display device, and different types of display devices may be mixed. For example, the display device 13a may be a HUD (Head-Up Display) instead of a touch panel.

[0025] In each of the driver's seat 12a, the passenger seat 12b, the left seat in the second row 12c, the right seat in the second row 12d, the left seat in the third row 12e, and the right seat in the third row 12f, speakers 14La and 14Ra, 14Lb and 14Rb, 14Lc and 14Rc, 14Ld and p14Rd, 14Le and 14Re, and 14Lf and 14Rf are arranged inside the headrest at the upper part of the backrest.

[0026] Hereinafter, the speakers 14La, 14Lb, 14Lc, 14Ld, 14Le, and 14Lf are also collectively referred to as the speaker 14L, and the speakers 14Ra, 14Rb, 14Rc, 14Rd, 14Re, and 14Rf are also collectively referred to as the speaker 14R. Further, hereinafter, the speakers 14R and 4L are also collectively referred to as the speaker 14. The speakers 14L and 14R each function as a left speaker and a right speaker that outputs stereo sound to the passenger P sitting in the corresponding seat 12.

[0027] In addition to the speaker 14 which is a headrest speaker, on the ceiling surface of the cabin 10, at positions corresponding to the upper parts of the driver's seat 12a, the passenger seat 12b, the left seat in the second row 12c, the right seat in the second row 12d, the left seat in the third row 12e, and the right seat in the third row 12f respectively, directional speakers 15a, 15b, 15c, 15d, 15e, and 15f that output sound toward the lower seat 12 are provided. Hereinafter, the directional speakers 15a, 15b, 15c, 15d, 15e, and 15f are also collectively referred to as the directional speaker 15.

[0028] In addition, in the cabin 10 of the moving body 2, an in-vehicle camera 16 is provided at a position where it can photograph the passengers P seated in the driver's seat 12a, the front passenger seat 12b, the left seat 12c in the second row, the right seat 12d in the second row, the left seat 12e in the third row, and the right seat 12f in the third row, respectively. The in-vehicle camera 16 is arranged, for example, above the windshield (not shown) of the moving body 2 (i.e., at a position close to the ceiling of the cabin 10).

[0029] The moving body 2 may also be provided with a media reader 17 which is a reading device for storage media such as a USB memory (registered trademark) and an SD memory card (registered trademark), and a CD / DVD drive 18 which is a reading device for storage media such as CDs and DVDs, at a position below the display device 13g which is a central display device on the instrument panel.

[0030] [1.3 Configuration of the Content Output Device] FIG. 3 is a diagram showing the configuration of the content output device 1 mounted on the moving body 2. The content output device 1 includes a processor 20, a memory 21, and a communication device 22. The memory 21 is constituted by, for example, a volatile and / or non-volatile semiconductor memory, and / or a hard disk device, etc.

[0031] The memory 21 stores in advance a user DB 23 (user database) and a content DB 24 (content database). The user DB 23 stores registration information of users who use the moving body 2 as passengers P. The registration information may include a face image of the user, age, a list of accounts of the viewing services to which the user subscribes, and a list of related-party relationships which is a list of user IDs of users having a related-party relationship.

[0032] It can be assumed that the content DB 24 stores in advance contents such as movies and games. The communication device 22 is a transceiver for the content output device 1 to wirelessly communicate with external devices (including the content server 4 and the game server 5) via the communication network 3. Further, the communication device 22 may include a transceiver for performing short-range wireless communication such as Bluetooth (registered trademark) with a terminal device (not shown) possessed by the passenger P when the passenger P boards the moving body 2.

[0033] The processor 20 is, for example, a computer equipped with a CPU (Central Processing Unit) or the like. The processor 20 may have a configuration including a ROM (Read Only Memory) in which a program is written, a RAM (Random Access Memory) for temporarily storing data, and the like. And the processor 20 includes an identification unit 26, an output unit 27, a determination unit 28, and a proposal unit 29 as functional elements or functional units.

[0034] These functional elements included in the processor 20 are realized, for example, by the processor 20, which is a computer, executing a program 25 stored in the memory 21. Note that the program 25 can be stored in any computer-readable storage medium. Alternatively, all or part of the above functional elements included in the processor 20 can also be configured by hardware including one or more electronic circuit components.

[0035] The identification unit 26 identifies each of the passengers P seated in each seat 12 of the moving body 2 and obtains identification information related to content viewing for each of the passengers P. In the present embodiment, the identification information includes the age of the corresponding passenger P, the seat position (i.e., the seating position) in the cabin 10, information on whether it is in a viewable state, service subscription information that is information on the viewing service to which the passenger P subscribes, and kinship information that is information on the kinship with other passengers P.

[0036] In the above, the "information on whether or not it is in a viewable state" may be, for example, information on whether or not the passenger P is sleeping. Further, the "information on kinship" may be, for example, information on the presence or absence of a parent-child relationship or a family relationship.

[0037] For example, the identification unit 26 acquires an image inside the cabin 10 by the in-cabin camera 16, and acquires each face image of the passenger P seated in the cabin 10 from the acquired image. The identification unit 26 refers to the user DB 23 stored in the memory 21, collates the acquired face image with the face images of each user stored in the user DB 23, and acquires the user ID of each passenger P, thereby identifying each passenger P.

[0038] The identification unit 26 acquires registration information for each identified passenger P from the user DB 23. As described above, the registration information may include the age of the passenger P, a list of accounts of the viewing services to which the passenger P subscribes, a list of user IDs of users having a kinship with the passenger P, and a kinship list indicating the type of kinship. The identification unit 26 determines the presence or absence of a kinship with other passengers P based on the user ID and kinship list of each passenger P.

[0039] In addition, the identification unit 26 identifies the seat 12 of each passenger P in the cabin 10 from the image inside the cabin 10 acquired from the in-cabin camera 16. Further, the identification unit 26 determines whether or not each passenger P is in a sleeping state from the face image of each passenger P acquired from the image.

[0040] Then, the identification unit 26 acquires, as identification information, for each passenger P, information on the seat 12 as the seating position of the passenger P, the age of the passenger P, a list of accounts of the viewing services to which the passenger P subscribes, a list of user IDs of other passengers P having a predetermined kinship with the passenger P, and information on whether or not the passenger P is in a viewable state in which the passenger P can view the content.

[0041] Here, the above "list of accounts of the subscribed viewing services" corresponds to the service subscription information in the present disclosure. Also, the "list of user IDs of other passengers P having a pre-determined kinship with the passenger P" corresponds to the "information on the kinship with other passengers P" of the passenger P in the present disclosure. Further, the parent-child relationship or family relationship corresponds to the "pre-determined kinship" in the present disclosure. Also, in the present embodiment, the above "information on whether or not the passenger P is in a viewable state where the passenger P can view the content" is, for example, information on whether or not the passenger P is in a sleeping state.

[0042] The output unit 27 outputs the content specified by the passenger P of the moving body 2 to the display device 13 mounted on the moving body 2 as the target content. For example, according to the prior art, the output unit 27 displays a list of accessible contents (hereinafter also referred to as a content list) on the display device 13 in front of the seat 12 in response to an instruction from the passenger P seated on the seat 12. The input of the display instruction of the content list to the output unit 27 can be performed, for example, by operating a button displayed on the display device 13 which is a touch panel.

[0043] The above content list may include, for example, a list of contents provided by the first content server 4a, the second content server 4b, and the game server 5 that the content output device 1 can communicate with through the communication device 22, a list of contents stored in the content DB 24 stored in the memory 21, and a list of names of contents stored in the storage media inserted into the media reader 17 and the CD / DVD drive 18.

[0044] Also, the above content list can be made to include information on the category of each content. The above category can be one representing the type of content, such as "movie", "drama", "game", etc. Alternatively, the above category may include the content classification of the content, such as "horror movie", "action movie", "romance drama", "role-playing game", etc.

[0045] According to the prior art, the output unit 27 can access the content server 4 related to the viewing service to which the passenger P who gave the instruction to display the content list subscribes, and obtain the names and categories of the content provided by the viewing service. Also according to the prior art, the output unit 27 can access the game server 5, the content DB 24, and the storage media inserted into the media reader 17 and the CD / DVD drive 18, and obtain the information on the names of the content that each can provide and the categories of the content.

[0046] Based on the service subscription information included in the identification information of the passenger P obtained by the identification unit 26, among the identification information of the passenger P who gave the instruction to display the content list (for example, using various accounts of the passenger P included in the service subscription information), the output unit 27 can access the content server 4 related to the viewing service to which the passenger P subscribes, and the game server 5.

[0047] The passenger P who gave the instruction to display the content list designates the desired content from the content list displayed on the display device 13 which is a touch panel, and instructs the output unit 27 to output the designated content. The output unit 27 outputs the designated content to the display device 13 as the target content. Hereinafter, the passenger P who designates the target content is referred to as the "target user".

[0048] Specifically, when the target content designated by the target user is the content provided by the viewing service, the output unit 27, based on the service subscription information of the target user, uses the account of the target user to obtain the restriction information related to the viewing of the target content and the data necessary for the output of the content (including video data, audio data, etc.) from the corresponding content server 4 of the viewing service.

[0049] The above "restriction information" regarding the viewing of the target content includes at least information on the viewing age restriction or the recommended target age (so-called R rating). The restriction information may also include information regarding the content of the content, such as "violent scenes" and "sexual content".

[0050] In the present embodiment, in particular, the output unit 27 outputs the target content to the display device 13 when the output of the target content is permitted according to the determination result of whether to permit the output of the target content in the determination unit 28 described later. Specifically, the output unit 27 determines the display device 13 arranged at a position within the cabin 10 visible from the seating position of the target user as the target display device to which the target content is to be output.

[0051] The output unit 27 determines, for example, the display device 13 in front of the target user seated on the seat 12 as the target display device. More specifically, when the target user is seated in the left seat 12c in the second row, for example, the output unit 27 may determine the display device 13c arranged on the back surface of the backrest of the driver's seat 12a in front of the target user as the target display device. The output unit 27 outputs the target content to the determined target display device.

[0052] On the other hand, when the output of the target content is not permitted in the determination unit 28, the output unit 27 does not output the target content to the display device 13. In this case, the output unit 27 may display a message indicating that the specified target content cannot be output on the target display device.

[0053] When the determination unit 28 determines to permit the output of the target content, if the restricted person is included among the passengers P, the output unit 27 reduces the output level of the reproduction sound of the target content output from the speaker 14 to less than a predetermined level. Alternatively, the output unit 27 may output the reproduction sound of the target content toward the seating position of the target user by the directional speaker 15. Specifically, for example, the output unit 27 outputs the reproduction sound by the directional speaker 15 arranged above the seat 12 where the target user is seated so that the reproduction sound cannot be heard by passengers P other than the target user.

[0054] Thereby, not only the video output of the target content but also the output of the reproduction sound is controlled, so that the target content can be output so as to more appropriately comply with the viewing restriction and / or access restriction regarding the target content.

[0055] The determination unit 28 acquires the identification information about each passenger P from the identification unit 26, and acquires the restriction information regarding the viewing of the target content via the output unit 27, and determines whether to permit the output of the target content in the output unit 27 based on the acquired restriction information and identification information.

[0056] For example, based on the identification information of each passenger P, the determination unit 28 determines whether a restricted person who should be restricted from viewing the target content according to the restriction information of the target content is included among the passengers P seated in the seat 12 where the display device 13, which is the target display device, is visible. When the determination unit 28 determines that a restricted person is included among the passengers P seated in the seat where the target display device is visible, the determination unit 28 does not permit the output of the target content to the target display device.

[0057] Thereby, the content output device 1 can appropriately comply with the viewing restriction regarding the content.

[0058] Hereinafter, the seat 12 where the display device 13, which is the target display device, is visible is also referred to as a visible seat. For each display device 13, it can be determined in advance which seat 12 is a visible seat. For example, for a display device 13 arranged in front of any one seat 12, the visible seats can be the above-mentioned one seat 12, other seats 12 on the right or left side of the above-mentioned one seat 12, and other seats 12 in the row one row behind the row of the above-mentioned one seat 12. That is, for example, the visible seats of the display device 13d arranged in front of the right seat 12d in the second row can be the right seat 12d in the second row, the left seat 12c in the second row on the left side of the right seat 12d in the second row, and the third row, that is, the left seat 12e and the right seat 12f in the third row, which is one row behind the right seat 12d in the second row.

[0059] However, the above-described method of determining visible seats is just an example, and the visible seats for each display device 13 can be arbitrarily determined in advance according to the configuration and arrangement of seats 12 in the cabin 10 and the arrangement of the display device 13.

[0060] When the determination unit 28 determines whether a restricted person is included among the passengers P sitting in the visible seats, the passengers P who are not in a viewable state among the passengers P may be excluded from the object of the above determination. Thereby, without unnecessarily restricting the output of the content, the viewing restriction on the content can be appropriately observed.

[0061] Specifically, the determination unit 28 can determine whether the passenger P is in a viewable state based on the information included in the identification information of each passenger P as to whether the passenger P is in a viewable state where the content can be viewed. As described above, in the present embodiment, the "information as to whether the passenger P is in a viewable state where the content can be viewed" is the information as to whether the passenger P is in a sleeping state. The determination unit 28 determines the passenger P in the sleeping state as a passenger not in a viewable state and excludes it from the object of determination as to whether it is the above-mentioned restricted person.

[0062] When the target content is content provided from one viewing service to which the target user subscribes, the determination unit 28 determines whether to permit the output of the target content in the output unit 27 based on the service subscription information and the kinship information included in the identification information of each of the passengers P. Thereby, it is possible to appropriately comply with the access restriction for the content.

[0063] For example, when the target content is content provided from one viewing service to which the target user subscribes, the determination unit 28 determines, based on the service subscription information and the kinship information of each of the passengers P, whether among the passengers P seated in the visible seats of the display device 13 which is the target display device, there is a person who does not have a predetermined kinship with the target user. And when among the passengers P seated in the visible seats, there is a person who does not have a predetermined kinship with the target user, the person without the kinship is determined as a person to be restricted whose viewing of the target content should be restricted, and the output of the target content in the output unit 27 is not permitted. As described above, in the present embodiment, the predetermined kinship is, for example, a parent-child relationship or a family relationship.

[0064] However, even when the target content is content provided from one viewing service to which the target user subscribes and among the passengers P seated in the visible seats of the target display device, there is a person who does not have the above-mentioned predetermined kinship with the target user, if all of the passengers P who do not have a predetermined kinship with the target user among the passengers P seated in the visible seats subscribe to the above-mentioned one viewing service, or have the above-mentioned predetermined kinship with another passenger P who subscribes to the above-mentioned one viewing service, the output of the target content in the output unit 27 is permitted. Thereby, while appropriately complying with the access restriction for the content, it is possible to execute the content output in accordance with the wishes of the passenger P.

[0065] When the determination unit 28 determines to permit the output of the target content in the output unit 27, the determination unit 28 determines whether there is a passenger P who can be a restricted person among the passengers P sitting in the seat 12 that is not a visible seat for the target display device. Then, the determination unit 28 notifies the output unit 27 that there is a passenger P who can be a restricted person among the passengers P sitting in the seat 12 that is not a visible seat.

[0066] The proposal unit 29 makes a proposal regarding the output of the content to the passenger P. Specifically, when the determination unit 28 determines not to permit the output of the target content, the proposal unit 29 proposes alternative content that can be permitted to be output instead of the target content to the passenger P who is the target user, or proposes a countermeasure for permitting the output of the target content. This proposal can be made, for example, by displaying a message indicating the content of the proposal on the display device 13 which is the target display device. Thereby, while taking into account the viewing restriction and access restriction of the content, the content output along with the wishes of each passenger can be executed as much as possible.

[0067] For example, when the determination unit 28 determines not to permit the output of the target content, the proposal unit 29 proposes to the target user, as the above-mentioned alternative content, content that has the same content as the target content and for which none of the passengers P sitting in the visible seats for the target display device are subject to viewing restriction based on the restriction information of the content.

[0068] Specifically, for example, when the target content is game content and different recommended target ages are shown in the restriction information of the game content according to the settings of the game, the proposal unit 29 proposes to the target user, as the alternative content, content that is the same game content as the target content but with the game settings changed to settings different from those of the target content.

[0069] Further, when the determination unit 28 determines not to permit the output of the target content, for example, the proposal unit 29 proposes, as alternative content, content that belongs to the same category as the target content and for which none of the passengers P sitting in the visible seats for the target display device are subject to viewing restrictions based on the restriction information of the content to the target user.

[0070] Specifically, for example, when the category of the target content is "horror movie" and the determination unit 28 determines not to permit the output of the target content due to the viewing age restriction included in the restriction information of the target content, the proposal unit 29 proposes, as alternative content, content that belongs to the same "horror movie" category as the target content and for which none of the passengers P sitting in the visible seats for the target display device are subject to viewing restrictions based on the restriction information of the content to the target user. This proposal can be made, for example, by displaying a message indicating the content of the proposal on the display device 13, which is the target display device. Note that the proposal unit 29 can search for the above alternative content from, for example, the above content list generated by the output unit 27.

[0071] In addition, when the target content is content provided by one viewing service and the determination unit 28 determines not to permit the output of the target content based on the service subscription information and the relationship information included in the identification information of the passenger P, if another viewing service different from the one viewing service provides the same content as the target content, the proposal unit 29 may propose the content to the target user as alternative content. For example, the proposal unit 29 can propose, as alternative content, the same content as the target content provided by the other viewing service on the condition that all of the passengers P sitting in the seats where the target display device is visible are subscribed to the other viewing service or have the above-mentioned predetermined relationship with the passengers P who are subscribed to the other viewing service. The proposal unit 29 can search for the above alternative content from, for example, the above content list generated by the output unit 27.

[0072] As a result, while appropriately complying with the access restrictions on the content, it is possible to execute content output that conforms to the wishes of individual passengers as much as possible.

[0073] When the determination unit 28 prohibits the output of the target content in the output unit 27, the proposal unit 29 may also propose that the restricted person or target user move to another seat 12 so that the restricted person cannot visually recognize the target content, as a countermeasure proposal for allowing the output of the target content. This proposal can be made, for example, by displaying a message indicating the content of the proposal on the display device 13g which is the central display device and / or the display device 13 which is the target display device. The above message may include, for example, words indicating the position of the current seat 12 of the restricted person or target user and the position of the recommended destination seat 12. Specifically, the above message may be, for example, "Passenger in the left seat of the second row, please move to the passenger seat." In addition to the above message, the proposal unit 29 may also display an image showing the movement of the restricted person or target user from the current seat 12 to the recommended destination seat 12 on the display device 13g.

[0074] When the determination unit 28 prohibits the output of the target content in the output unit 27 and seat movement of a plurality of passengers P is required for the output of the target content to be permitted, the proposal unit 29 may also propose a change in the seat arrangement of the passengers P within the cabin 10 of the moving body 2 as a countermeasure proposal for allowing the output of the target content. This proposal can be made, for example, by displaying a seat arrangement diagram showing the recommended seat positions for each of the passengers P on the display device 13g which is the central display device. For example, the above seat arrangement diagram may be composed of a schematic diagram showing the positions of each seat 12 within the cabin 10 and the name or user ID of each passenger P superimposed on the respective positions of each seat 12 in the schematic diagram.

[0075] [1.4 Operation of Content Output Device] Next, the operation of the content output device 1 will be described. FIG. 4 is a flowchart showing the procedure of a content output method executed by a processor 20 which is a computer of the content output device 1. The processing shown in FIG. 4 starts when the power of the mobile body 2 is turned on and the power of each device including the content output device 1 mounted on the mobile body 2 is turned on, and thereafter, it is repeatedly executed until the power of the mobile body 2 is turned off.

[0076] Referring to FIG. 4, when the processing starts, an identification unit 26 of the content output device 1 determines whether a display instruction for a content list has been input to any of the display devices 13 which are touch panels (S100). When the display instruction for the content list is not input (S100, NO), the identification unit 26 repeats the processing of step S100 and waits until the display instruction for the content list is input.

[0077] On the other hand, when a display instruction for the content list is input to any of the display devices 13 (S100, YES), the identification unit 26 identifies each of the passengers P seated on each seat 12 of the mobile body 2 and acquires identification information related to content viewing for each of the passengers P (S102). Next, in response to the input of the display instruction for the content list, an output unit 27 accesses the content server 4, the game server 5, the content DB 24, the media reader 17 and / or the storage media inserted into the CD / DVD drive 18, and acquires a list of the names of accessible contents and the category information of each content (S104). The output unit 27 displays a content list including the list of the names of the acquired contents on the display device 13 where the display instruction was input (S106).

[0078] Next, the output unit 27 determines whether a designation of the content to be output has been input from the display device 13 on which the content list is displayed (S108). When the designation of the content is not input (S108, NO), the output unit 27 repeats the processing of step S108 and waits until the designation of the content is input.

[0079] On the other hand, when the content is specified and input (S108, YES), the output unit 27 designates the specified content as the target content, accesses the content server 4, the game server 5, or the storage medium inserted into the media reader 17 or the CD / DVD drive 18, and acquires the restriction information of the target content and the data for output (S110). As described above, in the present embodiment, the passenger P who inputs the content specification is referred to as the target user.

[0080] Next, the determination unit 28 determines whether to permit the output of the target content in the output unit 27 based on the restriction information of the target content acquired via the output unit 27 and the identification information acquired in step S102 (S112).

[0081] When the determination unit 28 determines to permit the output of the target content (S112, YES), the display device 13 arranged in front of the seat 12 of the target user is set as the target display device, and the target content is output to the target display device (S114). When the output of the target content is completed, the output unit 27 ends this process.

[0082] On the other hand, when the determination unit 28 determines not to permit the output of the target content in step S112 (S112, NO), the proposal unit 29 makes a proposal regarding the output of the content to the passenger P (S116). The above proposal can be made, for example, by displaying a message and / or an image on the display device 13 which is the target display device or the display device 13g which is the central display device. As described above, the above proposal can be a proposal for alternative content in place of the target content or a proposal for countermeasures for permitting the output of the target content.

[0083] Subsequently, the proposal unit 29 acquires a response input from the target user with respect to the above proposal (S118). The above response can be input, for example, via the display device 13 which is the target display device. The proposal unit 29 determines whether the input response from the target user is affirmative (S120). An affirmative response is, for example, when the above proposal is a proposal of alternative content, a response indicating acceptance of using the alternative content as the target content. Also, for example, when the above proposal is a countermeasure for permitting the output of the target content, it can be a response indicating completion of the execution of the countermeasure.

[0084] When the response input from the target user is affirmative (S120, YES), the proposal unit 29 instructs the output unit 27 to output the content according to the above proposal, and transfers the process to step S110. Here, "the output of the content according to the above proposal" means, when the proposal of alternative content is accepted, outputting the alternative content as the target content, and when the proposal of the countermeasure is accepted, it means the output of the content regarded as the target content in step S110.

[0085] When the process is transferred to step S110, the identification unit 26 may newly detect the seat position of each passenger P, and update the identification information of each passenger P based on the detected seat position information.

[0086] On the other hand, when the response input from the target user in step S120 is negative (S120, NO), the proposal unit 29 ends this process. At that time, the proposal unit 29 may display a message indicating that the target content cannot be output on the display device 13 which is the target display device.

[0087] Here, steps S104, S112, and S114 shown in FIG. 4 respectively correspond to the identification step, determination step, and output step in the present disclosure.
