The video reproduction device 100 and the cooperation device 300 may communicate via an access point (not shown) installed in the user's home 10, or may communicate without using an access point (not shown).

Next, the video reproduction device 100 will be described in detail.

FIG. 2 is a block diagram showing an example of the functional configuration of the video reproduction device 100. The video reproduction device 100 includes, for example, a storage unit 101, a communication unit 102, and a control unit 103.

The storage unit 101 stores information for operating the video reproduction device 100. The storage unit 101 is realized by, for example, a ROM (Read Only Memory), a RAM (Random Access Memory), or the like.

Further, the storage unit 101 stores device information related to the cooperation device 300. Further, the storage unit 101 may store the video information in which the environmental information is set.

The device information includes, for example, information for identifying the cooperation device 300, information indicating the type of the cooperation device 300, information indicating the type of the function mounted on the cooperation device 300, and information indicating a settable value related to the function. It is configured in association with. In the following description, the information indicating the type of the cooperation device 300 is referred to as a device type. Further, in the following description, the information indicating the type of the function mounted on the cooperation device 300 is referred to as a function type. The function type is at least one of temperature, humidity, air volume, wind direction or illuminance, and voice.

For example, the device identification information may be a device number, a serial number, an IP (Internet Protocol) address, a MAC (Media Access Control) address, or the like assigned to the cooperation device 300.

The communication unit 102 communicates with the cooperation device 300. The communication unit 102 is realized by, for example, a NIC (Network Interface Card) or the like.

For example, the communication unit 102 transmits a device information request to the cooperation device 300 (air conditioner 301, lighting device 302, etc.) in the user's house 10. For example, the communication unit 102 transmits a device information request to the cooperation device 300 (air conditioner 301, lighting device 302, etc.) connected to the LAN in the user's house 10.

Here, it is assumed that the cooperation device 300 (air conditioning device 301, lighting device 302, etc.) that can cooperate with the video reproduction device 100 can determine whether or not the device information request has been received. Upon receiving the device information request, the cooperation device 300 responds to the video playback device 100 with the device type, one or more function types, and information indicating a value that can be set for each function type. Alternatively, when one function is mounted on the cooperation device 300, when the cooperation device 300 receives the device information request, the cooperation device 300 responds to the video playback device 100 with the device type and information indicating a settable value. May be good. The video reproduction device 100 associates the device identification information of the cooperation device 300 with the received device type, the function type, and information indicating a settable value related to the function, and stores the device information as device information in the storage unit 101. The above configuration is an example of the configuration of the video playback device 100 and the cooperation device 300, and is not intended to limit the configuration of the video playback device 100 and the cooperation device 300.

FIG. 3 is a diagram showing an example of device information. Specifically, FIG. 3 shows a table in which the device type, the device identification information, the function type, and the settable range are associated with each other. Note that FIG. 3 is an example of device information, and does not mean that the device information is limited to the configuration and information shown in FIG. For example, FIG. 3 shows a "settable range (min, max)", which is limited to the device information being configured to include a configurable minimum value and a configurable maximum value. Not the purpose. For example, the device information may be configured by specifying a settable value. Further, when the device information is configured to include a settable minimum value and a settable maximum value as the settable range, a predetermined discrete value within the settable range can be set in the cooperation device 300. Even if there is, it may be possible to set a continuous value within the settable range.

For example, when the storage unit 101 stores the device information shown in FIG. 3, the storage unit 101 stores information on the "air conditioner", "air purifier", "lighting", and "fan" as the device information of the cooperation device 300. Remember. Further, for example, the device identification information of the "air conditioner" is "aaa.aaa.bbbb.x". Further, the "air conditioner" can set a value of level 0 or more and level 3 or less with respect to the "air volume". Further, the "air conditioner" can be set to face downward or upward with respect to the "wind direction".

The control unit 103 controls the entire video reproduction device 100. The control unit 103 is realized by a processor such as a CPU (Central Processing Unit). For example, when the processor reads and executes the program stored in the storage unit 101, the processor operates as the control unit 103.

The control unit 103 includes, for example, a video reproduction unit 104, an environment information acquisition unit 105, and an environment control unit 106.

The video reproduction unit 104 reproduces the video information. For example, when the video reproduction unit 104 receives a reproduction instruction of the video information via an operation means (not shown, a remote controller, etc.), the video reproduction unit 104 reproduces the video information. For example, the video reproduction unit 104 may read the video information stored in a storage medium (DVD (Digital Versatile Disk), BD (Blu-ray Disk), etc.) and reproduce the video information. Alternatively, when the storage unit 101 stores the video information, the video reproduction unit 104 may read the video information stored in the storage unit 101 and reproduce the video information.

The environmental information acquisition unit 105 acquires environmental information preset in the video information.

The environmental control unit 106 controls the air conditioner 301 based on the environmental information. Further, the environment control unit 106 controls the illuminance of the lighting device 302 based on the environment information.

Further, when the cooperation device 300 includes a speaker, the environment control unit 106 may control the cooperation device 300 so as to output sound from the speaker of the cooperation device 300 based on the environmental information. When the environmental information includes information related to voice, it is assumed that the voice data is stored in at least one of the storage unit 101 and the cooperation device 300.

Next, the environmental information will be described in detail with reference to FIG.

The environment information is configured by associating, for example, information indicating the reproduction order in the video information, the device type, and information indicating the control content. For example, the video provider sets environmental information in the video information and creates the video information in which the environmental information is set. In the following description, information indicating the reproduction order in the video information is referred to as reproduction order identification information. The reproduction order identification information may be, for example, a time code, a frame number, or the like attached to the video information, and the details thereof are not limited as long as the information indicates the reproduction order. In the following description, information indicating the control content is referred to as a control instruction.

FIG. 4 is a diagram showing an example of environmental information. Specifically, FIG. 4 shows a table in which the reproduction order identification information, the device type, and the control instruction related to the video information of the video ID “mov0001” are associated with each other. Note that FIG. 4 is an example of environmental information, and is not intended to limit the environmental information to the configuration and information shown in FIG.

The control instruction is composed of, for example, a set of a function type and a target value related to the function type. In the following description, the target value related to the function type is referred to as a control value.

The control value may be a value set in the cooperation device 300. Alternatively, the control value may be the amount of change in the value set in the cooperation device 300.

When the function type is voice, the control value may be information related to voice (for example, a file path of voice data).

For example, when the video reproduction unit 104 reproduces a video (video information) of a night scene, an environment in which the playback order identification information of the scene, the device type “lighting”, and the control instruction “decrease illuminance” are associated with each other. The information may be set to video information.

Further, for example, when the image reproduction unit 104 reproduces an image (image information) of a sunny outdoor scene, the reproduction order identification information of the scene, the device type "lighting", and the control instruction "setting of the illuminance level" are performed. Of the possible range, the environmental information associated with "Set the illuminance level to the maximum level" may be set in the video information.

Further, for example, when the video reproduction unit 104 reproduces a video (video information) of a storm scene, the playback order identification information of the scene, the device type "air conditioner", and the control instruction "air volume level settable range" Of these, the environmental information associated with "setting the air volume level to the maximum level" may be set in the video information.

Further, for example, when the video reproduction unit 104 reproduces a video (video information) of a scene in which the season changes from autumn to winter, the playback order identification information of the scene, the device type "air conditioner", and the control instruction "unit time" are used. Environmental information associated with "lowering the temperature for each" may be set in the video information.

For example, the video playback device 100 sets the "air conditioner" to "wind direction" when playing back the video associated with the playback order identification information "00.01.10.00" based on the environmental information shown in FIG. Instruct to "set downward".

Further, when the image reproduction device 100 reproduces the image associated with the reproduction order identification information "00.05.20.00" based on the environmental information shown in FIG. 4, the "air purifier" is set to "air volume". Is instructed to "set to level 3". Further, the video playback device 100 sets the "temperature" in the "air conditioner" when playing back the video associated with the playback order identification information "00.05.20.00" based on the environmental information shown in FIG. Instruct to "raise 1 ° C".

Further, when the video playback device 100 reproduces the video associated with the playback order identification information "00.20.40.00" based on the environmental information shown in FIG. 4, the "illuminance" is set to the "lighting device". Is instructed to "set to level 2".

Further, the video playback device 100 sets the "temperature" in the "air conditioner" when playing back the video associated with the playback order identification information "00.50.00.00" based on the environmental information shown in FIG. Instruct to "lower by 0.5 ° C per minute until it drops by 2 ° C".

Next, the operation of the video reproduction device 100 will be described.

FIG. 5 is a flowchart showing an example of the operation of the video reproduction device 100. In the following description, it is assumed that the storage unit 101 stores the device information shown in FIG. Further, it is assumed that the environmental information shown in FIG. 4 is set in the video information. Further, in the following description, an IP address will be used as the device identification information, but this does not mean that the device identification information is limited to the IP address.

In step S11, the video reproduction unit 103 starts reproducing the video information. Specifically, when the video reproduction unit 103 receives the reproduction instruction of the video information, the video reproduction unit 103 starts the reproduction of the video information. For example, the user may instruct the video reproduction device 100 to reproduce the video information by using a remote controller or the like.

In step S12, the environmental information acquisition unit 105 determines whether or not the environmental information is associated with the reproduction order identification information of the video information to be reproduced. When the environment information is not associated with the reproduction order identification information of the image information to be reproduced (step S12: No), the image reproduction unit 104 reproduces the image of the next reproduction order. Then, the control returns to step S12 and continues the process.

On the other hand, when the environment information is associated with the reproduction order identification information of the reproduction target of the video information (step S12: Yes), the environment information acquisition unit 105 reproduces the reproduction target of the video information based on the environment information. The device type and the control instruction associated with the order identification information are specified (step S13). Then, the control transitions to step S14.

For example, it is assumed that the environmental information shown in FIG. 4 is set as the video information. Then, it is assumed that the reproduction order identification information of the image information to be reproduced, which is reproduced by the image reproduction unit 104, is "00.20.40.00". In that case, the environmental information acquisition unit 105 determines that the environmental information is associated with the reproduction order identification information of the video information to be reproduced. Then, the environment information acquisition unit 105 specifies the device type “lighting” and the control instruction (function type, control value) “(illuminance, set to level 2)”.

When the video reproduction unit 103 receives the reproduction instruction of the video information, the environment information acquisition unit 105 may acquire the environment information set in the video information to be reproduced. Further, the environment information acquisition unit 105 may store the acquired environment information in the storage unit 101. In that case, when the video reproduction unit 103 starts reproducing the video information, the environment information acquisition unit determines whether or not the reproduction order identification information of the reproduction target of the video information becomes the reproduction order identification information included in the acquired environment information. 105 may be determined.

In step S14, the environment control unit 106 determines whether or not the specified device type is included in the device information registered in advance. Specifically, the environment control unit 106 determines whether or not the device type associated with the reproduction order identification information of the video information to be reproduced is registered in the device information stored in the storage unit 101.

When the specified device type is not included in the device information (step S14): No, the video reproduction unit 104 reproduces the video in the next playback order. Then, the control returns to step S12 and continues the process.

On the other hand, when the specified device type is included in the device information (step S14: Yes), the environment control unit 106 determines the function type and the settable range associated with the specified device type based on the device information. And the IP address are specified (step S15). Then, the control transitions to step S16. In the following description, the set of the function type and the settable range is referred to as device function information.

For example, when the device type specified by the environment control unit 106 is "lighting", the environment control unit 106 determines whether or not the device type "lighting" is included in the device information. For example, when the storage unit 101 stores the device information shown in FIG. 3, the environment control unit 106 determines that the device type “lighting” is included in the device information. Then, the environment control unit 106 specifies the function type “illuminance” and the settable range “(level 0, level 4)” as the device function information. Here, when the device function information is the function type "illuminance" and the settable range "(level 0, level 4)", the linked device 300 associated with the device function information has an illuminance of level 0 or more and level 4 or less. Supposes that can be set. Further, the environment control unit 106 specifies the device identification information (for example, IP address) “aaa.aaa.bbb.c” of the device type “lighting”.

In step S16, the environment control unit 106 determines whether or not the function type included in the specified control instruction is associated with the specified device type based on the device information. Specifically, the environment control unit 106 determines whether or not the function type included in the specified control instruction is included in the specified device function information.

When the function type included in the specified control instruction is not associated with the specified device type in the device information (step S16: No), the video reproduction unit 104 reproduces the video in the next reproduction order. Then, the control returns to step S12 and continues the process. As a result, it is possible to prevent the video reproduction device 100 from instructing the cooperation device 300 to perform an unexecutable process.

On the other hand, when the function type included in the specified control instruction is associated with the specified device type in the device information (step S16: Yes), the control transitions to step S17.

In step S17, the environment control unit 106 determines whether or not the control value included in the specified control instruction is within the settable range associated with the specified function type in the device information. Specifically, the environment control unit 106 determines whether or not the control value included in the specified control instruction is within the settable range associated with the specified function type in the specified device function information.

For example, it is assumed that the control value included in the control instruction specified by the environment control unit 106 is "set to level 2". Further, it is assumed that the settable range specified by the environment control unit 106 is "(level 0, level 4)". And, that the settable range is "(level 0, level 4)", it is assumed that the value of level 0 or more and level 4 or less can be set in the cooperation device 300 associated with the settable range. In that case, the environment control unit 106 determines that the control value "set to level 2" is within the settable range.

When the control value included in the specified control instruction is not within the settable range associated with the specified function type in the device information (step S17: No), the environment control unit 106 sets the specified function type. A value that can be set is determined as a control value (step S18). Then, the control transitions to step S19.

For example, when the control value included in the control instruction is smaller than the settable range registered as the device information, the environment control unit 106 may determine the minimum value in the settable range as the control value. Similarly, when the control value included in the control instruction is larger than the settable range registered as the device information, the environment control unit 106 determines the control value and the maximum value in the settable range as the control value. May be good.

On the other hand, when the control value included in the specified control instruction is within the settable range associated with the specified function type in the device information (step S17: Yes), the control transitions to step S19.

In step S19, the environment control unit 106 transmits a control instruction to the linked device 300 of the specified device identification information (step S19). Specifically, the environment control unit 106 instructs the cooperation device 300 associated with the reproduction order identification information of the reproduction target to perform processing based on the control instruction regarding the function type associated with the reproduction order identification information of the reproduction target. ..

For example, it is assumed that the environmental information shown in FIG. 4 is set as the video information. Then, it is assumed that the reproduction order identification information of the image information to be reproduced, which is reproduced by the image reproduction unit 104, is "00.20.40.00". In that case, the environment control unit 106 sends a control instruction (function type, control value) "(illuminance, level 2) to the cooperation device 300 of the device identification information" aaa.aaa.bbb.c "corresponding to the device type" lighting ". Set to) ”is sent. For example, when the device identification information "aaa.aaa.bbbb.c" is the IP address of the cooperation device 300, the environment control unit 106 illuminates the IP address "aaa.aaa.bbbb.c" with a level 2 illuminance. Instruct to set to. Further, for example, the environment control unit 106 may wirelessly transmit a radio wave including device identification information and a control instruction (Bluetooth (registered trademark) or the like). Then, when the cooperation device 300 receives the device identification information for identifying its own cooperation device 300, the cooperation device 300 may execute the process based on the received control instruction.

When one function type is associated with the device identification information in the device information, the environment control unit 106 can set the device identification information associated with the specified device type based on the device information instead of the process of step S15. The pair with the range and the IP address may be specified. Then, the control may transition to step S17.

Further, when the control value included in the specified control instruction is not within the settable range associated with the specified function type in the device information (step S17: No), the video reproduction unit 104 performs the next reproduction. The video in sequence may be played. Then, the control may return to step S12 and continue the process. The above flow is an example, and the present embodiment is not limited to this. According to this embodiment, the environment such as temperature and lighting can be changed according to the scene in which the video information is reproduced.

Set (input) the position (device position) of. For example, it is assumed that an air conditioner, an air purifier, lighting, and a fan are arranged as a cooperation device 300 in the user's house 10. In that case, the user uses the input unit 404 (touch panel, keyboard, button, etc.) to enter the viewer 1001, the air conditioner 1011, the air purifier 1012, and the lighting 1013 in the setting area 1000 of the setting screen displayed in FIG. , The fan 1014 is arranged.

Then, when the user performs an operation of completing the setting of the viewing position information and the device position information (for example, pressing the "OK" button shown in FIG. 10), the control unit 403 is arranged in the setting area 1000 of the setting screen. The viewing position information and the device position information are determined based on the viewer and the cooperation device 300. For example, the control unit 403 determines the viewing position information and the device position information as the coordinate values on the coordinate axes set for the setting area 1000 on the setting screen. Then, the control unit 403 transmits the viewing position information and the device position information to the video reproduction device 100 via the communication unit 401.

FIG. 11 shows an example of viewing position information stored in the storage unit 101. Further, FIG. 12 shows an example of device position information stored in the storage unit 101. 11 and 12 show viewing position information and device position information as coordinate values with respect to the two-dimensional coordinate axes set for the setting area 1000 of the setting screen. Here, the coordinate axes set for the setting area 1000 shown in FIG. 10 are orthogonal to the origin (0,0) at the upper left vertex of the setting area 1000 (rectangular area), the X axis in the horizontal direction, and the X axis on the plane. The direction to do is set as the Y axis. Note that FIG. 11 is an example of viewing position information, and is not intended to limit the viewing position information to the format shown in FIG. Similarly, FIG. 12 is an example of device position information, and is not intended to limit the device position information to the format shown in FIG. For example, the viewing position information and the device position information may be expressed as three-dimensional coordinates.

Next, the operation of the video reproduction device 100 according to the present embodiment will be described.

FIG. 13 is a flowchart showing an example of the operation of the video reproduction device 100.

When the environment control unit 106 determines that the specified device type is included in the device information (step S15 shown in FIG. 5), the device position information management unit 107 between the cooperation device 300 of the specified device type and the viewing position. The distance is calculated (step S101).

In step S102, the environment control unit 106 updates the control value based on the distance between the device position and the viewing position. Then, the control transitions to step S15 shown in FIG.

For example, it is assumed that the environment information shown in FIG. 4 is set in the video information reproduced by the video reproduction unit 104. Then, it is assumed that the reproduction order identification information of the reproduction target of the video information is "00.05.20.00". In that case, the environmental information acquisition unit 105 is associated with the device type "air purifier" associated with the reproduction order identification information of the video information to be reproduced and the device type "air purifier" based on the environmental information.

In that case, the device position information management unit 107 has the viewing position (X, Y) = (3,3) and the device position (X, Y) = (4,4) of the cooperation device 300 of the device type "air purifier". ) Calculate the distance between.

Further, for example, it is assumed that the device type specified by the environment control unit 106 is "lighting". In that case, the environment control unit 106 sets the illuminance increased (or decreased) from the control value included in the control instruction based on the distance between the cooperation device 300 of the device type “lighting” and the viewing position. In addition, you may instruct the cooperation device 300 of the device type "lighting".

For example, assume that the control instruction specified by the environment control unit 106 is "set the illuminance to level 2." Further, the distance between the cooperation device 300 of the device type "lighting" and the viewing position is longer than the recommended distance of the device type "lighting". In that case, the environment control unit 106 may change the control value so that the environment control unit 106 sets the illuminance higher than the level 2 illuminance. As a result, even if the distance between the viewing position and the cooperation device 300 of the device type "lighting" is farther than the distance assumed by the creator of the environmental information, the video playback device 100 according to the present embodiment can be used. It contributes to making the viewer feel the brightness assumed by the creator of the environmental information.

The communication unit 502 communicates with the video reproduction device 100 and the cooperation device 300. The communication unit 502 is realized by, for example, a NIC or the like.

The control unit 503 controls the entire server device 500. The control unit 503 is realized by a processor such as a CPU. For example, when the processor reads and executes the program stored in the storage unit 501, the processor operates as the control unit 503.

When the storage unit 501 stores the video information, the control unit 503 may transmit the video information to the video playback device 100 in response to a request from the video playback device 100.

The environmental information management unit 504 manages the environmental information set in the video information.

For example, when the communication unit 501 receives a signal requesting environmental information (hereinafter referred to as an environmental information request), the environmental information management unit 504 extracts the environmental information from the storage unit 501 in response to the environmental information request. .. Then, the environmental information management unit 504 transmits the extracted environmental information to the transmission source of the environmental information request.

Further, for example, when the video reproduction unit 104 starts reproducing the video information, the environment control unit 106 transmits an environment information request including the video ID. When the environmental information management unit 504 receives the environmental information request including the video ID, the environmental information management unit 504 extracts the video information from the storage unit 501 based on the received video ID. Here, it is assumed that the environmental information is set in the video information extracted by the environmental information management unit 504. Then, the environmental information management unit 504 transmits the extracted video information to the video playback device 100.

Then, the user environment information 505 may store the video information in which the user environment information is set in the storage unit 501.

For example, when the video reproduction unit 104 starts reproducing the video information, the environment control unit 106 transmits a user environment information request including the video ID and the user ID. When the user environment information management unit 505 receives the user environment information request including the video ID and the user ID, the user environment information management unit 505 extracts the user environment information from the storage unit 501 based on the received video ID and the user ID. The user environment information management unit 505 transmits the extracted user environment information to the source of the user environment information request. Then, the environment control unit 106 controls the cooperation device 300 based on the received user environment information instead of the environment information set in the video information to be reproduced.

Alternatively, the user environment information management unit 505 may store the video information in which the user environment information is set in the storage unit 501. In that case, when the user environment information management unit 505 receives the user environment information request including the video ID and the user ID, the user environment information is set from the storage unit 501 based on the received video ID and the user ID. Extract video information. Then, the user environment information management unit 505 transmits the video information in which the user environment information is set to the transmission source of the user environment information request. Then, the video reproduction unit 104 reproduces the received video information. Further, the environment control unit 106 controls the cooperation device 300 based on the user environment information set in the video information.

Then, the user environment information management unit 505 may store the generated standard user environment information in the storage unit 501. Then, the environment control unit 106 may control the cooperation device 300 based on the standard user environment information.

For example, the user environment information management unit 505 may learn a plurality of user environment information associated with the same video ID by machine learning (reinforcement learning or the like) to generate standard user environment information. For example, the user environment information management unit 505 performs reinforcement learning so that the more similar the control instructions in the plurality of user environment information are, the higher the score is set for the control instructions for each scene of the video in a predetermined range. , Standard user environment information may be generated.

The user environment information management 505 may update the video information by setting the standard user environment information as the video information. Then, the user environment information 505 may store the video information in which the standard user environment information is set in the storage unit 501.

When the user environment information management unit 505 receives the standard user environment information request including the video ID, the user environment information management unit 505 extracts the standard user environment information from the storage unit 501 based on the received video ID. The user environment information management unit 505 transmits the extracted standard user environment information to the source of the standard user environment information request. Then, the environment control unit 106 controls the cooperation device 300 based on the received standard user environment information in place of the environment information preset for the video information to be reproduced.
