'Usage state information' is, for example, information of interest including the degree of interest of the user, and the state of the corresponding device including changes in activity in the corresponding device (eg, power on/off, display on/off, power saving mode entry) It may correspond to various information related to.

The power control module 210 selects a second electronic device whose activity changes within a service area among at least one second electronic device 230 , 231 , and 233 as an 'effective device' (eg, the mobile terminal 1004 of FIG. 10A or FIG. 11 ). It can be determined as the mobile terminal 1104 of Fig. 12, the mobile terminal 1204, the mobile terminal 1206, and / or the mobile terminals 1304, 1306, and 1308 of Fig. 13. Here, 'activity change' is a corresponding This may include, but is not limited to, driving of a processor in a device, execution of a specific app in the device, and occurrence of power consumption exceeding a certain standard in the device.

The power control module 210 may determine the device of interest 230 corresponding to the user based on the number of available devices. The 'device of interest' 230 may correspond to a device on which the user's interest is currently focused. The power control module 210 may transmit, to the device of interest 230 , device-of-interest information notifying that the corresponding device is determined as a device of interest or a device of highest interest.

For example, if there is one valid device within the service area, the power control module 210 may determine the valid device as the device of interest 230 corresponding to the user. Alternatively, when there are a plurality of valid devices in the service area, the power control module 210 may determine the device of interest 230 corresponding to the user based on interest level information 240 corresponding to each of the valid devices. At this time, the interest level information 240 corresponding to each of the valid devices includes, for example, identification information (ID) corresponding to each valid device, location of each valid device, type of each valid device (eg, TV, laptop, tablet, mobile), user interest in each valid device (eg, 1 to 5), and power consumption of each valid device, but is not necessarily limited thereto.

At this time, the user's level of interest may be, for example, what the power control module 210 receives determined by the second electronic device (or valid device), and the power control module ( 210) may have been determined directly. The user's level of interest is, for example, a touch input, a remote control input, a typing input generated in each second electronic device such as the device of interest 230, and at least one input interaction of the user's gaze detected by the second electronic device. It may be determined based on the duration of the second electronic device, the amount of power consumption of the task performed in the second electronic device, and the type of content reproduced in the second electronic device, but is not necessarily limited thereto.

The interest information 240 may be stored, for example, in a memory of the power control module 210 or a storage of a cloud server, but is not necessarily limited thereto.

The power control module 210 may activate a low power setting for the first electronic device 220 based on the level of interest information. The power control module 210 may, for example, set to lower the backlight of the first display 225, set to lower the reproduction quality of content output from the first display 225, and set the first electronic device 220 Low power setting by any one or a combination of a setting to lower the sound of ), a setting to activate the power saving mode of the first electronic device 220, and a setting to turn off the power of the first electronic device 220 can be activated, but is not necessarily limited thereto. In addition, the power control module 210 may activate various low power settings capable of reducing power consumption of the first electronic device 220 .

According to embodiments, the device of interest 230 may activate the low power setting for the first electronic device 220 by transmitting a low power setting activation signal instead of the power control module 210 .

The power control module 210 may adjust at least one of strength and application range of the low power setting for the first electronic device 220 based on the level of interest information.

In addition, the power control module 210 establishes an association between the second content displayed on the second display 235 of the device of interest 230 and the first content displayed on the first display 225 of the first electronic device 220. Based on the degree, whether to activate the low power setting for the first electronic device 220 may be determined. For example, when the degree of association between the second content and the first content is higher than a preset criterion, the power control module 210 may deactivate the low power setting for the first electronic device 220 . In contrast, when the degree of association between the second content and the first content is lower than or equal to a preset criterion, the power control module 210 may activate a low power setting for the first electronic device 220 .

At this time, the degree of association is, for example, whether the meta information of the first content matches the keyword input to the device of interest 230, the similarity between the meta information of the first content and the meta information of the second content, and the first content It may be determined based on at least one of whether the device of interest 230 reproduces the same through screen mirroring, but is not necessarily limited thereto.

For example, when the low power setting is activated in the first electronic device 220, the power control module 210 generates a pre-scheduled user input from either the first electronic device 220 or the device of interest 230. The activated low power setting for the first electronic device 220 may be deactivated depending on whether or not the electronic device 220 is configured.

The 'prearranged user input' may be a user input capable of inferring that the user's interest has moved from the device of interest 230 back to the first electronic device 220 or another electronic device. The prearranged user input includes, for example, a remote control input instructing at least one of a channel change, a volume change, and a power save mode release button of the first electronic device 220, and an activated low power setting generated by the device of interest 230. It may include at least one of an input requesting to switch to an inactive state, and a departure of the user's gaze for a predetermined time or more detected by the device of interest 230 , but is not necessarily limited thereto.

The power control module 210 may cancel the activated low power setting when a corresponding user input occurs in the first electronic device 220 or the device of interest 230 .

The power control module 210 may be included in, for example, a hub, a service server, a cloud server, or a second electronic device that integrates and manages a smart home. Alternatively, the power control module 210 may be a hub, a service server, a cloud server, or the second electronic device itself.

Hereinafter, the operation of the power control module 210 will be described with reference to FIGS. 3 to 21 , and the operation of the second electronic device (device of interest 230 ) will be described with reference to FIG. 22 .

The power control module 210 may detect the number of valid devices whose activities have changed within the service area among at least one second electronic device. The power control module 210 may determine a device of interest corresponding to the user based on the number of available devices. For example, when the number of valid devices is singular, the power control module 210 may determine the valid device as a device of interest corresponding to the user. In contrast, when the number of valid devices is plural, the power control module 210 may determine one of the plurality of valid devices as a device of interest based on a user's level of interest corresponding to each of the plurality of valid devices. In this case, the degree of interest of the user corresponding to each of the plurality of valid devices may be determined, for example, by the method shown in FIG. 6 .

Referring to FIG. 4 , a device of interest of a user according to an embodiment is a first electronic device (eg, TV) (P ₁ ) (eg, the electronic devices 101 and 102 of FIG. 1 and the first electronic device of FIG. 2 ). 220, the first electronic device 705 of FIG. 7, the first electronic device 805 of FIG. 8, the first electronic device 901 of FIG. 9, the first electronic device 1003 of FIG. 10A, FIG. 11 1103 of FIG. 12 , 1203 of FIG. 13 , 1303 of FIG. 13 , 1901 of FIG. 19 , and/or 1 of FIG. 20 . In the electronic device 2001), the second electronic device (eg, mobile terminal) (P ₂ ) (eg, the electronic device 101 and 102 of FIG. 1, the device of interest 230 of FIG. 2, and the second electronic device of FIG. 7 Device 701, second electronic device 801 of FIG. 8, second electronic device 1004 of FIG. 10A, second electronic device 1104 of FIG. 11, second electronic device 1204, 1206 of FIG. , the second electronic device 1304, 1306, 1308 of FIG. 13, the second electronic device 1903 of FIG. 19, and/or the second electronic device 2003 of FIG. 10), the power control module ( Example: The power control module 210 of FIG. 2 , the power control module 703 of FIG. 7 , the power control module 803 of FIG. 8 , and/or the power control module 2300 of FIG. 23 ) are the first electronic device Figures 410 , 420 , 430 , 440 , 450 , and 460 illustrating a process of activating the low power setting of (P ₁ ) are shown.

For example, as shown in drawing 410 , when a user watches a TV (P ₁ ) in a home, the power control module 210 may determine the TV (P ₁ ) as a device of interest. As shown in drawing 420, the user activates the mobile terminal (P ₂ ) in an on state while watching TV, and continuously uses the mobile terminal (P ₂ ) for, for example, 5 minutes or more, as shown in drawing 430. A separate input such as At this time, the degree of interest of the user corresponding to the corresponding device may be determined by a separate input. The separate input is, for example, a touch input generated by the mobile terminal (P ₂ ), a remote control input, a typing input, and at least one input interaction (interaction) of the user's gaze detected by the mobile terminal (P ₂ ). It may include at least one of a duration, a power consumption of a task performed in the mobile terminal P ₂ , and a type of content reproduced in the mobile terminal P 2 , but is not necessarily limited thereto.

In this case, the power control module 210 may activate a low power setting for the first electronic device regardless of whether a predetermined screen time-out period for the first display of the TV P ₁ has elapsed.

After the low power setting of the TV (P ₁ ) is activated, the user may end use of the mobile terminal as shown in drawing 450 . For example, when a prearranged user input such as end of use of the mobile terminal occurs, the power control module 210 considers that the user's interest in the TV (P ₁ ) has increased, and low power for the TV (P ₁ ) settings can be turned off. At this time, the user input promised in advance to release the low power setting may be, for example, a remote control input of the TV (P ₁ ), such as a channel change, volume change, and a TV sleep mode release button, or turn off the screen of the mobile terminal, The user's gaze deviation from the mobile terminal may be included, but is not necessarily limited thereto.

As the low power setting for the TV (P ₁ ) is canceled, the power control module 210 may restore the backlight of the TV (P ₁ ) to a previous value as shown in the drawing 460 .

When a previously promised user input does not occur in operation 570, the power control module 210 may maintain a low power setting for the TV (P ₁ ). In contrast, when a prearranged user input occurs in operation 570 , the power control module 210 releases and deactivates the low power setting for the TV P ₁ in operation 580 . The power control module 210 may cancel activation of the low power setting through, for example, a process as shown in FIG. 8 below.

In operation 735, the power control module 703 may determine whether the number of detected valid devices is two or more. The power control module 703 may determine a device of interest corresponding to the user based on the number of available devices.

For example, if it is determined in operation 735 that the number of valid devices is less than two, that is, one, the power control module 703 detects a change in the activity of the valid device (eg, the terminal P ₂ ). can do. Here, the change in activity is, for example, as shown in FIG. 6 , in addition to whether or not a certain level of power is quickly consumed, whether video content is reproduced, and whether the duration of an input interaction elapses for N minutes, the corresponding effective device (e.g., : It may further include whether the first electronic device 705 is located within the viewing angle of the terminal P ₂ .

For example, if a change in activity is detected in a corresponding valid device (eg, terminal P ₂ ), the corresponding valid device (eg, terminal P ₂ ) may inform the power control module 703 that a change in activity has been detected. can Accordingly, in operation 765, the power control module 703 may cancel the device of interest setting for the first electronic device 705 and activate a low power setting for the first electronic device 705 in operation 770. In this case, the power control module 703 may set an effective device (eg, terminal P ₂ ) as a device of interest instead of the first electronic device 705 .

Alternatively, for example, if it is determined in operation 735 that the number of valid devices is greater than or equal to two, in operation 750 the power control module 703 detects a change in activity of the plurality of valid devices, Among them, one valid device showing the highest user interest may be selected as the device of interest.

In operation 755, the power control module 703 may inform the effective device selected in operation 750 whether low power setting for the first electronic device 705 is executed or not through, for example, a pop-up menu.

In operation 760, the power control module 703 may determine whether the user approves the valid device for the pop-up menu notified in operation 755. When it is determined in operation 760 that the user's approval is not obtained, the power control module 703 may end the operation.

On the other hand, if it is determined in operation 760 that the user's approval has been obtained, the power control module 703 releases the device of interest for the first electronic device 705 in operation 765, and in operation 770 the first electronic device 705 ) to enable low-power settings.

8 is a diagram for describing operations between a first electronic device, a second electronic device, and a power control module for deactivation of a low power setting according to an embodiment. Referring to FIG. 8 , at least one second electronic device (P ₁ , P ₂ , .. , P _N ) 801 (eg, the electronic devices 101 and 102 of FIG. 1 , FIG. 2 ) according to an embodiment. The device of interest 230 of FIG. 7 , the second electronic device 701 of FIG. 7 , the second electronic device 1004 of FIG. 10A , the second electronic device 1104 of FIG. 11 , the second electronic device 1204 of FIG. 12 , 1206), the second electronic device 1304, 1306, and 1308 of FIG. 13, the second electronic device 1903 of FIG. 19, and/or the second electronic device 2003 of FIG. 10), the power control module 803 (eg, the power control module 210 of FIG. 2, the power control module 703 of FIG. 7, and/or the power control module 2300 of FIG. 23), and the first electronic device (P ₁ ) 805 ( Examples: electronic devices 101 and 102 in FIG. 1 , first electronic device 220 in FIG. 2 , first electronic device 705 in FIG. 7 , first electronic device 901 in FIG. 9 , first electronic device 901 in FIG. 10A 1 electronic device 1003, the first electronic device 1103 of FIG. 11, the first electronic device 1203 of FIG. 12, the first electronic device 1303 of FIG. 13, the first electronic device 1901 of FIG. , and/or operations 810 to 845 between the first electronic device 2001 of FIG. 20 , the low power setting for the first electronic device P ₁ 705 may be released.

For example, when a signal indicating that the user's interest in the second electronic device 801 has decreased is received, the power control module 803 selects the second electronic device 801 determined as a device of interest as a device of interest. The low power setting for the first electronic device 805 may be deactivated by canceling in and canceling activation of the low power setting for the first electronic device 805 .

Here, a signal that can be regarded as a decrease in the user's interest in the second electronic device 801 is, for example, the second electronic device 801 is in an inactive state (eg, a screen off state of the second electronic device 801). , processing stop state of the second electronic device 801), or an input device (eg, a sensor module and/or a camera module) of the second electronic device 801 capable of tracking the user's gaze for a specified time The deviation of the user's line of sight may be confirmed or may be a remote control input to the first electronic device 805, but is not necessarily limited thereto.

For example, in operation 810, any one second electronic device ('device of interest') (eg, P ₂ ) 801 among a plurality of second electronic devices is determined, and the first electronic device 805 Low power settings can be activated.

At this time, in operation 815, the second electronic device 801 may determine whether a transition to an inactive state, such as turning off the screen, has occurred. When transition to the deactivated state occurs in operation 815, the second electronic device 801 may be deactivated in operation 825. As the second electronic device 801 is deactivated, in operation 830, the power control module 703 releases the second electronic device 801 from the device of interest, and in operation 845 sets low power for the first electronic device 805. can be disabled.

If the transition to the inactive state does not occur in operation 815, in operation 820, the second electronic device 801 may determine whether or not the user's gaze has deviated for more than N minutes. When it is determined in operation 820 that the user's gaze has not departed for more than N minutes, the second electronic device 801 may perform operation 815 .

In contrast, when it is determined in operation 820 that the user's gaze has departed for more than N minutes, in operation 825 the second electronic device 801 may be deactivated. As the second electronic device 801 is deactivated, in operation 830, the power control module 703 releases the second electronic device 801 from the device of interest, and in operation 845 sets low power for the first electronic device 805. can be disabled.

In addition, when a remote control input to the first electronic device 805 occurs in operation 840, the power control module 803 deactivates the low-power setting for the first electronic device 805 in operation 845 so that the first electronic device ( The low power setting for power consumption reduction in 805) may be converted to a previous inactive state.

(Example: mobile terminal 1104 in FIG. 11, mobile terminal 1204, mobile terminal 1206 in FIG. 12, and/or mobile terminal 1304, 1306, 1308 in FIG. 13) A diagram 1001 representing the situation is shown.

As shown in the drawing 1001 , the electronic devices 1003 and 1004 within the service area may be in a standby state as shown in the drawing 1011 . The power control module 210 may determine whether the electronic devices 1003 and 1004 corresponding to the users are within a service area by using, for example, a home network and GPS of the electronic devices 1003 and 1004. .

Thereafter, while content is reproduced on the TV 1003 within the service area as shown in drawing 1012, the processor of the mobile terminal 1004 may be activated as shown in drawing 1013. The power control module 210 may set the TV 1003 to which the operation signal according to content reproduction is transmitted first among the electronic devices 1003 and 1004 within the service area as a device of interest corresponding to the user 1002 .

The time for the user 1002 to perform a task such as SNS or online shopping on the mobile terminal 1004 while watching the TV 1003 may last, for example, 5 minutes or more, as shown in a drawing 1014 . When the duration of use of the mobile terminal 1004 exceeds a preset time (eg, 3 minutes), the power control module 210 sets the mobile terminal 1004 as the user's device of interest, while the TV 1003 You can release the setting of the device of interest for .

After canceling the setting of the device of interest for the TV 1003, the power control module 210 transmits a signal for activating the low power setting to the TV 1003 as shown in a drawing 1015, and as shown in a drawing 1016, the TV ( 1003) can activate the low power setting.

Referring to FIG. 10B, electronic devices 1003 and 1004 within a service area as shown in a drawing 1001 are in a standby state as shown in a drawing 1021, and then as shown in a drawing 1022, the TV ( While content is being reproduced in 1003 , a processor of the mobile terminal 1004 may be activated as shown in a drawing 1023 . The power control module 210 may set the TV 1003 activated first among the electronic devices 1003 and 1004 within the service area as a device of interest corresponding to the user 1002 .

While watching the TV 1003, the user 1002 may perform a task that requires a large battery consumption, such as playing a game, on the mobile terminal 1004 as shown in a drawing 1024. At this time, when the power consumption by the game play performed in the mobile terminal 1004 is greatly increased compared to the preset standard or the power consumption of the TV 1003, the power control module 210 controls the mobile terminal 1004 as a user's While setting as a device of interest, the setting of the device of interest for the TV 1003 may be canceled.

After canceling the setting of the device of interest for the TV 1003, the power control module 210 transmits a signal for activating the low power setting to the TV 1003 as shown in a drawing 1025, and as shown in a drawing 1026, the power control module 210 ( 1003) can activate the low power setting.

Also, referring to FIG. 10C , the electronic devices 1003 and 1004 in the service area as shown in the drawing 1001 are in a standby state as shown in the drawing 1031 and are in the service area as shown in the drawing 1032. While content is reproduced on the TV 1003, a processor of the mobile terminal 1004 may be activated as shown in a drawing 1033. The power control module 210 may set the TV 1003 activated first among the electronic devices 1003 and 1004 within the service area as a device of interest corresponding to the user 1002 .

The same modality as the content provided by the TV 1003, such as when the user 1002 plays video content (eg, YouTube®) on the mobile terminal 1004 as shown in a drawing 1034 while watching the TV 1003. A task of outputting content using visual modality and auditory modality) may be performed. When the TV 1003 and the mobile terminal 1004 provide the same type of content (eg, video content), the user 1002 mainly focuses on one content, so the power control module 210 controls the TV 1003 ), the mobile terminal 1004 that outputs the content played later may be set as the user's device of interest, while the setting of the device of interest for the TV 1003 may be released.

After canceling the setting of the device of interest for the TV 1003, the power control module 210 transmits a signal for activating the low power setting to the TV 1003 as shown in a drawing 1035, and as shown in a drawing 1036, the TV ( 1003) can activate the low power setting.

11 is a diagram for explaining a low power control method when there is only one effective device located in a service area according to an exemplary embodiment. Referring to FIG. 11 , a power control module according to an embodiment (eg, power control module 210 of FIG. 2 , power control module 703 of FIG. 7 , power control module 803 of FIG. 8 , and/or The first electronic device (eg, the electronic devices 101 and 102 of FIG. 1 , the first electronic device 220 of FIG. 2 , The first electronic device 705 of FIG. 7, the first electronic device 805 of FIG. 8, the first electronic device 901 of FIG. 9, the first electronic device 1003 of FIG. 10A, and the first electronic device of FIG. 12 device 1203, first electronic device 1303 in FIG. 13, first electronic device 1901 in FIG. 19, and/or first electronic device 2001 in FIG. Mobile terminal 1104, which is a device (e.g., mobile terminal 1004 in FIG. 10A, mobile terminal 1204, mobile terminal 1206 in FIG. 12, and/or mobile terminal 1304, 1306, 1308 in FIG. 13) A diagram 1101 showing a situation in the same space and a diagram 1005 showing a situation where a TV 1103 as a first electronic device and a mobile terminal 1104 as an effective device are in different spaces are shown.

As shown in drawings 1101 and 1105, when there is only one mobile terminal 1104 within the service area, the power control module 210 controls the low power setting of the TV 1103 only with the activation state of the mobile terminal 1104. can do.

As shown in drawing 1110, when the user's interest increases due to the duration of the interaction time with the mobile terminal or an increase in power consumption in a situation where the TV is playing content, the power control module 210 As shown in 1120, ultra wide band (UWB) communication may be activated between the TV 1103 and the mobile terminal 1104.

UWB communication may be performed using impulse waves rather than sine wave communication. In UWB communication, electromagnetic waves are exchanged between transmitters and receivers, and the distance can be obtained by dividing the departure time/arrival time by the speed of light. More specifically, in UWB communication, distance can be obtained using time difference of arrival (TDoA) and/or two way ranging (TWR), which is the time required for radio waves to reach from a transmitter to a receiver and from a receiver to a transmitter. At this time, the clocks of the transmitter and the receiver should be the same as possible.

Measuring distance with UWB communication does not indicate directionality. Therefore, the direction can be determined by borrowing two antennas included in each device. When two antennas are used, since a time difference occurs between an antenna closer to the receiving end and an antenna farther from the receiving end, the direction between the two devices can be determined by measuring the distance and forming a triangle.

When the distance and direction between the TV 1103 and the mobile terminal 1104 are confirmed through UWB communication, the power control module 210 controls the TV 1103 and the mobile terminal 1104 based on this as shown in the drawing 1130. The distance between them can be estimated.

The power control module 210 estimates the angle between the TV 1103 and the mobile terminal 1104 as shown in a drawing 1140 through the distance, direction, and estimated distance between the TV 1103 and the mobile terminal 1104, thereby estimating the mobile terminal 1104. An angle of view of the user 1102 based on the terminal 1104 may be calculated. The power control module 210 may estimate an angle using, for example, an angle of arrival (AOA) technique.

For example, there is a difference in the time at which signals reach each electronic device, and accordingly, a phase difference may occur between signals input to each electronic device. The mobile terminal 1104 may calculate the direction (angle) in which the TV 1103 is located using the phase difference. The mobile terminal 1104 is equipped with, for example, three antennas, and can detect high-precision positions including directions and angles between UWB devices by a 3D AOA technique.

For example, as shown in drawing 1150, when the viewing angle of the user 1102 matches that of the TV 1103, the power control module 210 determines that the user 1102 focuses on the mobile terminal 1104 while watching TV. It is determined that the mobile terminal 1104 is a device of interest, and a low power setting for the TV 1103 may be activated. Here, 'the viewing angle of the user 1102 matches that of the TV 1103' means that the display of the TV 1103 is located within the viewing angle of the user 1102, and/or content reproduced by the display of the TV 1103. It can be understood as meaning that is at an angle that the user 1102 can see.

Alternatively, as shown in drawing 1160, when the viewing angle of the user 1102 does not match that of the TV 1103, the power control module 210 determines that the user is not watching the TV 1103, and the TV 1103 You can enable low power settings for

As shown in diagrams 1101 and 1105, when the number of valid devices in the service area is singular, the power control module 210 performs UWB communication between the mobile terminal 1104 and the TV 1103 so that the mobile terminal 1104 The low power setting for the TV 1103 may be activated regardless of whether the viewing angle of the user 1102 calculated in ) matches the first electronic device of the TV 1103 .

12 is a diagram for explaining a low power control method when a plurality of valid devices are located in a service area and the plurality of valid devices are located in different spaces according to an embodiment.

Referring to FIG. 12 , a power control module according to an embodiment (eg, power control module 210 of FIG. 2 , power control module 703 of FIG. 7 , power control module 803 of FIG. 8 , and/or The first electronic device (eg, the electronic devices 101 and 102 of FIG. 1 , the first electronic device 220 of FIG. 2 , The first electronic device 705 of FIG. 7, the first electronic device 805 of FIG. 8, the first electronic device 901 of FIG. 9, the first electronic device 1003 of FIG. 10A, and the first electronic device of FIG. 11 device 1103, the first electronic device 1303 in FIG. 13, the first electronic device 1901 in FIG. 19, and/or the first electronic device 2001 in FIG. A diagram 1201 is shown showing a situation in which a device, mobile terminal 1204, is in the same space, and a second effective device, mobile terminal 1206, is in another space. In this case, the mobile terminal 1204 may belong to the user 1202 , and the mobile terminal 1206 may belong to the user 1205 .

For example, it is assumed that a plurality of valid devices 1204 and 1206 are located in a service area as shown in FIG. 12 and the low power setting of the TV 1204 is controlled only by the activation state of the mobile terminal 1206 among them. In this case, although the other user 1202 is watching the TV 1204, the low power setting of the TV 1204 is activated, which may cause inconvenience to the other user 1202.

In this case, the power control module 210 may determine whether to reflect the activation state of the mobile terminal 1206 to the low power setting of the TV 1203 through UWB communication between the mobile terminal 1206 and the TV 1203 .

For example, as shown in drawing 1210, in a situation where the TV 1203 and the mobile terminal 1206 are located in different spaces, the degree of interest of the user 1205 in the mobile terminal 1206 is in the mobile terminal 1204. The interest of the user 1202 may increase more significantly. In this case, the power control module 210 may determine the mobile terminal 1206 among the mobile terminal 1204 and the mobile terminal 1206 as the device of interest (or the highest priority device of interest).

The power control module 210 may transmit a signal activating UWB communication between the mobile terminal 1206 determined as a device of interest and the TV 1203 as shown in a drawing 1220 . The power control module 210 may obtain information about the distance and direction between the mobile terminal 1206 and the TV 1203 calculated through UWB communication.

The power control module 210 determines the distance between the mobile terminal 1206 and the TV 1203 as shown in a drawing 1230 based on the distance and direction information between the mobile terminal 1206 and the TV 1203. can be estimated

The power control module 210 determines the viewing angle of the user 1205 based on the mobile terminal 1206 as shown in a diagram 1240 based on the distance, direction, and distance between the mobile terminal 1206 and the TV 1203. can confirm.

When it is determined that the viewing angle of the user 1205 does not match that of the TV 1203, the power control module 210 determines the state of the user 1205 of the mobile terminal 1206 (eg, the user 1205 as shown in a drawing 1250). ) is not watching the TV 1203), and the activation state of the mobile terminal 1206, which is a device of interest, may not be reflected in the low power setting for the TV 1203.

For example, the TV 1203 may be located outside the viewing angle of the user 1205 of the mobile terminal 1206 as a device of interest, and the mobile terminal 1204 adjacent to the TV 1203 may be determined as a next-priority device of interest. In this case, the power control module 210 may activate a low power setting for the TV 1203 according to whether the TV 1203 matches the viewing angle of the user 1202 of the mobile terminal 1204 .

13 is a diagram for explaining a process of obtaining user approval for activation of a low power setting by using a device of interest among a plurality of valid devices when there are a plurality of valid devices located in a service area according to an exemplary embodiment; .

The mobile terminal 1304 is in the same space, and the mobile terminal 1306, which is the second effective device, and the mobile terminal 1308, which is the third effective device, are located in different spaces from the mobile terminal 1304, which is the first effective device, respectively. A diagram 1301-3 showing the situation is shown.

In diagrams 1301-1, 1301-2, and 1301-3, mobile terminal 1304 belongs to user 1302, mobile terminal 1306 belongs to user 1305, and , the mobile terminal 1308 may belong to the user 1307 . The power control module 210 may determine whether a mobile terminal corresponding to users is within a service area by using, for example, a home network and GPS of each electronic device.

For example, as shown in drawings 1310-1 to 1310-3, users 1302, 1305, and/or users 1302, 1305, 1307), the TV 1303 can reproduce content as shown in a drawing 1320 by any one user.

As the user 1302 searches the Internet through the mobile terminal 1304 while content is being reproduced on the TV 1303, the processor of the mobile terminal 1304 may be activated as shown in a drawing 1330.

As shown in a drawing 1340, the power control module 210, when the duration of the input interaction in the mobile terminal 1304 exceeds a preset time (eg, 5 minutes), the mobile terminal 1304 is a device of interest (or a top-level device). device of interest). The power control module 210 obtains the distance, direction, and angle between the mobile terminal 1304 and the TV 1303 by activating UWB communication between the mobile terminal 1304 determined as the device of interest and the TV 1303 to obtain the user 1302. It is possible to determine whether the viewing angle of matches the TV 1303.

If the viewing angle of the user 1302 matches that of the TV 1303, the power control module 210 may use the mobile terminal 1304 to obtain the user's approval for activation of the low power setting for the TV 1303. . At this time, the user's approval may be performed, for example, by the user selecting an 'execute' button included in a pop-up menu (eg, "Do you want to activate low power setting for TV?") on the screen of the mobile terminal 1304. can

As such, when there are a plurality of valid devices 1304, 1306, and/or 1308 within the service area, the power control module 210 prior to activating the low power setting for the TV 1303, the device of interest, By obtaining approval for the activation of the low power setting from the user 1302 of the mobile terminal 1304, the user 1302 can execute the low power setting by reflecting the needs of other users in the same space.

14 is a diagram for explaining a method of adjusting at least one of strength and application range of a low power setting for a first electronic device based on interest level information according to an embodiment. Referring to FIG. 14 , a power control module according to an embodiment (eg, power control module 210 of FIG. 2 , power control module 703 of FIG. 7 , power control module 803 of FIG. 8 , and/or A diagram 1400 for explaining how the power control module 2300 of FIG. 23 adjusts the application range of the low power setting according to the level of interest of the user is shown.

The power control module 210 according to an embodiment, based on interest level information including a level of interest of a user corresponding to a mobile terminal as a device of interest, first electronic device (eg, the electronic devices 101 and 102 of FIG. 1 , The first electronic device 220 of FIG. 2 , the first electronic device 705 of FIG. 7 , the first electronic device 805 of FIG. 8 , the first electronic device 901 of FIG. 9 , the first electronic device of FIG. 10A device 1003, the first electronic device 1103 in FIG. 11, the first electronic device 1203 in FIG. 12, the first electronic device 1303 in FIG. 13, the first electronic device 1901 in FIG. 19, and And/or at least one of strength and application range of the low power setting for the TV, which is the first electronic device 2001 of FIG. 20 , may be adjusted.

For example, the power control module 210 may control the strength of the low power setting for the TV by differentially determining the level of interest of the user according to the task being performed in the mobile terminal and the duration of use of the mobile terminal.

For example, when the task being performed in the mobile terminal is online shopping or SNS usage, the power control module 210 may control the low power setting of the TV to 'light power saving' or '1'. When the task being performed in the mobile terminal is video content reproduction, the power control module 210 may control the low power setting of the TV to 'medium power saving' intensity or '3' intensity. Alternatively, when the task being performed in the mobile terminal is game app execution, the power control module 210 may control the low power setting of the TV to 'strong power saving' or '5'.

Alternatively, the power control module 210 may, for example, control the low power setting of the TV to 'light power saving' intensity when the duration of use of the mobile terminal elapses 5 minutes, and the duration of use of the mobile terminal is 15 minutes. If it elapses, the low power setting of the TV can be controlled to 'medium power saving' intensity. In addition, the power control module 210 may control the low power setting of the TV to 'strong power saving' intensity when the duration of use of the mobile terminal elapses 30 minutes.

For example, when the low power setting is controlled to 'light power saving' intensity, the TV's backlight setting value is adjusted from 20 to 12, or the image quality (resolution) of the content played on the TV is adjusted one level lower than the preset value. It can be. When the low power setting is controlled to 'mid-power saving' intensity, the TV's backlight setting is adjusted from 12 to 5, the image quality (resolution) of the content played on the TV is adjusted two levels lower than the preset value, or the TV's A power saving mode may be activated. Alternatively, when the low power setting is controlled to the intensity of 'strong power saving', the display of the TV may be switched to an off state, only sound may be reproduced, or power of the TV may be turned off.

15 is a flowchart illustrating a method of activating a low power setting according to a user's level of interest according to another embodiment. In the following embodiments, each process may be performed sequentially, but not necessarily sequentially. For example, the order of each process may be changed, or at least two processes may be performed in parallel.

Referring to FIG. 15 , a power control module according to an embodiment (eg, the power control module 210 of FIG. 2 , the power control module 703 of FIG. 7 , the power control module 803 of FIG. 8 , and/or The power control module 2300 of FIG. 23 may activate the low power setting according to the user's interest through operations 1510 to 1560. The processes of operations 1510 to 1560 shown in FIG. 15 may be directly performed by the power control module 210 or a second electronic device (eg, the electronic device 101 or 102 of FIG. 1 or the device of interest in FIG. 2 ). 230, second electronic device 701 of FIG. 7, second electronic device 801 of FIG. 8, second electronic device 1004 of FIG. 10A, second electronic device 1104 of FIG. 11, FIG. 12 The second electronic device 1204, 1206 of FIG. 13, the second electronic device 1304, 1306, 1308 of FIG. 13, the second electronic device 1903 of FIG. 19, and/or the second electronic device 2003 of FIG. ) may be performed.

In operation 1510, the power control module 210 may determine whether or not the power consumption of the second electronic device is consumed faster than a predetermined level or higher than before. The power control module 210 queries power consumption information of the second electronic device through, for example, a power management program, and compares the searched information with the power consumption of the second electronic device to determine the power consumption of the second electronic device. It can be determined whether or not it is consumed faster than a certain level compared to the previous one.

For example, if it is determined in operation 1510 that the power consumption of the second electronic device is consumed faster than a predetermined level or more, in operation 1540 the power control module 210 controls the second content displayed on the second electronic device and the first electronic device. It is possible to determine whether there is a relationship with the first content displayed on the device. Here, 'association' may be determined by, for example, the degree of association between the second content and the first content described through FIGS. 16 and 17 below.

When it is determined in operation 1540 that the second content and the first content are related, the power control module 210 may again determine in operation 1510 whether the power consumption of the second electronic device is consumed faster than a predetermined level or higher. In contrast, if it is determined in operation 1540 that the second content and the first content are not related, in operation 1550, the power control module 210 determines whether the first electronic device (eg, TV(P ₁ )) is located within the UWB azimuth. can decide

For example, when it is determined that the first electronic device (eg, TV(P ₁ )) is located within the UWB azimuth, in operation 1560, the power control module 210 may activate a low power setting for the first electronic device. . In contrast, when it is determined that the first electronic device (eg, TV(P ₁ )) is not located within the UWB azimuth, the power control module 210, in operation 1510, consumes power of the second electronic device faster than a predetermined level or more than before. You can decide whether to consume it or not.

When it is determined in operation 1510 that the power consumption of the second electronic device is consumed faster than a predetermined level, in operation 1520, the power control module 210 may determine whether video content is reproduced in the second electronic device. In this case, whether the video content is reproduced can be determined by whether a codec service is performed in the second electronic device.

When it is determined in operation 1520 that video content is reproduced, the power control module 210 may perform operation 1510 again. In contrast, when it is determined in operation 1520 that video content is not reproduced, in operation 1530, the power control module 210 may determine whether the duration of the input interaction occurring in the second electronic device passes N minutes. The input interaction may include, for example, a touch input, a remote control input, a typing input, and a user's gaze detected by the second electronic device. The duration of the input interaction may be defined differently for each type of second electronic device and/or for each task (eg, online shopping, SNS, game) performed in the second electronic device.

In operation 1530, when the duration of the input interaction has passed N minutes, in operation 1540, the power control module 210 establishes a correlation between the second content displayed on the second electronic device and the first content displayed on the first electronic device. As described above, operation 1510 may be determined, or operation 1550 and operation 1560 may be performed to activate low power setting for the first electronic device.

Referring to FIG. 16 , a power control module according to an embodiment (eg, power control module 210 of FIG. 2 , power control module 703 of FIG. 7 , power control module 803 of FIG. 8 , and/or The power control module 2300 of FIG. 23 is a first electronic device (eg, the electronic devices 101 and 102 of FIG. 1 , the first electronic device 220 of FIG. 2 , and the first electronic device 705 of FIG. 7 ) , the first electronic device 805 of FIG. 8, the first electronic device 901 of FIG. 9, the first electronic device 1003 of FIG. 10A, the first electronic device 1103 of FIG. 11, the first electronic device of FIG. 12 First content and interests displayed on the electronic device 1203, the first electronic device 1303 of FIG. 13, the first electronic device 1901 of FIG. 19, and/or the first electronic device 2001 of FIG. The second electronic device determined as the device (eg, the electronic devices 101 and 102 of FIG. 1 , the device of interest 230 of FIG. 2 , the second electronic device 701 of FIG. 7 , and the second electronic device 801 of FIG. 8 ) ), the second electronic device 1004 of FIG. 10A, the second electronic device 1104 of FIG. 11, the second electronic devices 1204 and 1206 of FIG. 12, and the second electronic devices 1304, 1306, and 1308 of FIG. ), the second electronic device 1903 of FIG. 19, and/or the second content displayed on the second electronic device 2003 of FIG. A diagram 1600 is shown for

For example, some of the meta information 1610 of the first content displayed on the first electronic device and the meta information 1630 of the second content displayed on the second electronic device ("Van Dijk", "Liverpool", " EPL") may be identical or similar.

In this case, the power control module 210 determines the degree of association between the second content and the first content by, for example, the number and/or matching ratio of the meta information 1610 and the meta information 1630. And, according to the degree of association, it is possible to determine whether to activate the low power setting for the first electronic device.

For example, the power control module 210 determines the degree of association as 1 when the number of matches between the meta information 1610 and the meta information 1630 is 1, and determines the degree of association when the number of matches is 3. It can be determined as '3'. Alternatively, when the number of matches between the meta information 1610 and the meta information 1630 is 5, the degree of association may be determined as '5'.

For example, when the degree of association is 3 or more, the power control module 210 may deactivate the low power setting for the first electronic device as shown in 1650, considering that there is a correlation between the second content and the first content. Alternatively, when the correlation degree is less than 3, the power control module 210 may activate the low power setting for the first electronic device considering that there is no correlation between the second content and the first content.

According to an embodiment, the power control module 210 determines the degree of association according to whether the meta information 1610 of the first content and a keyword input to the second electronic device match, and activates the low power setting for the first electronic device. You can decide whether or not

A drawing 1700 for explaining a method of determining whether to activate a low power setting according to the degree of association between a second content displayed on a mobile terminal or a tablet determined as a device of interest is shown.

For example, after the first content is played on the TV as shown in drawing 1710, the second content can be played on the tablet as shown in drawing 1720. In this case, when screen mirroring is executed on the tablet as shown in drawing 1730, the second content displayed in drawing 1740 may be mirrored to the TV as shown in drawing 1750.

In this way, when the second content displayed on the tablet is identically reproduced on the TV by screen mirroring, the power control module 210 determines that the degree of association between the first content and the second content is high (eg, degree of association 5). By determining, as shown in a drawing 1760, the low power setting for the TV may be deactivated.
