Hereinafter, a method for detecting a distance for watching TV according to the present invention will be described in detail with reference to FIGS. 1 to 6.

3 is a flowchart illustrating a TV viewing distance detection method according to an embodiment of the present invention.

First, the sensor unit 200 detects (or measures / confirms) whether an object (or viewer) exists within a preset distance or whether an object exists within a preset area. Here, the distance or the area is within the corresponding EPG information by using the Electronic Program Guide (EPG) information provided from the TV 20 or the set-top box 30 interworking with the TV viewing distance sensing device 10. Based on the viewing age information for each broadcast content and preset viewing distance information for each age (or viewing area information for each age), the distance or area is dynamically set in real time according to the viewing age information of the broadcasting content currently being output on the TV 20 ( Or change).

At this time, the sensor unit 200 may detect whether an object exists in a corresponding distance or area for a predetermined time (for example, 3 seconds) or more in order to reduce the possibility of errors.

In addition, the control unit 700, in the state of grasping the fixture (for example, including a sofa, furniture, etc.) existing within a predetermined distance (or area) by a pre-processing operation, in addition to the fixture through the sensor unit 200 Additionally, an object entering within a corresponding distance (or area) may be detected.

In addition, the control unit 700 performs an image analysis function on an object existing within the distance or an object existing within the area to determine whether the object is a person, and if the person is a person, whether the person is a youth or an adult, You can also check whether or not you are an infant or toddler.

As an example, the viewing age of the children's bus tayo animation currently being broadcast on the TV's infant programming channel is all ages, and the preset first distance (or first reference distance) is 2 meters according to the viewing age, and the preset first An area (or a first reference area) is included in the sensor unit 200 in a state where a radius of 2 meters is set from the TV viewing distance sensing device 10 (or the TV 20 / set-top box 30). The ultrasonic sensor detects whether an object (or person) approaching within the first distance is present (or located) within the first distance for a predetermined time (for example, 3 seconds).

As another example, Cang-gu, currently broadcasting on a TV channel, cannot be dried, so the viewing age of the animation is 12 years or older, and the preset second distance (or second reference distance) is 2.5 meters according to the viewing age. In a state in which a 2 area (or a 2nd reference area) is set to a radius of 2.5 meters from the TV viewing distance sensing device 10 (or the TV 20 / set-top box 30), the sensor unit 200 The included motion recognition sensor checks whether an object (or a person) movement is detected in the second area for a predetermined time (for example, 3 seconds) (S310).

Thereafter, when the sensing state of the object is maintained within a preset distance for a predetermined time or more, or when the motion sensing state of the object is maintained in a preset area for a predetermined time or longer, the control unit 700 displays the broadcast content. Is controlling the TV 20 being output, or the set-top box 30 connected to the TV 20, temporarily pausing the output of broadcast content being output from the TV 20, and preset in the TV 20 Control to output a guide image (or guide content).

In addition, the control unit 700 outputs preset warning content (or warning information) through the display unit 500 and / or the audio output unit 600.

In addition, the control unit 700 interlocks with the TV 20 and / or the set-top box 20 to temporarily store (or buffer) the broadcast content in the storage unit 400 from the time when the broadcast content is temporarily suspended. do. At this time, the control unit 700, for the convenience of viewers to watch continuously in the future, the broadcast content from a specific time point that is before the preset time (for example, 5 seconds) from the time of the temporary pause to the storage unit 400 It can also be stored temporarily.

For example, when an object (for example, a person) is detected within the first distance of 3 seconds or more, which is the preset time (or when the sensing state of the object is maintained within the first distance of 3 seconds or more), The control unit 700 controls the set-top box 30 connected to the TV 20, stops the output of the little bus Tayo animation 410 being output through the TV 20 shown in FIG. 4, and As illustrated in FIG. 5, the first guide image 510 is preset through the TV 20, and the first preset image is controlled through the display unit 500 and / or the audio output unit 600. Print out warning information (e.g., 2 meters away from the TV).

In addition, the control unit 700 is received through the set-top box 30 from the first time point (for example, October 01, 2018 at 6:05:10 pm) when the output of the little bus Tayo animation is stopped. Temporarily store the broadcast content of the little bus Tayo animation in the storage unit 400.

As another example, when the motion of an object is detected in the second area for 3 seconds or more, which is the preset time (or when the motion detection state of the object is maintained in the second area for 3 seconds or more), the controller The 700 controls the set-top box 30 connected to the TV 20, stops outputting the animation through the TV 20 and stops outputting the animation, and the second preset through the TV 20. It controls to output a guide image, and outputs predetermined second warning information (for example, 2.5 meters or more away from the TV) through the display unit 500 and / or the audio output unit 600.

In addition, the control unit 700 is a predetermined time (for example, 5 seconds) from the second time point (for example, October 01, 2018, 5:10:25 pm) when the output of the animation is stopped due to not being able to dry the duckbill. From the previous third time point (for example, October 1, 2018 at 5:10 and 20 seconds), the corresponding Cang-gu received through the set-top box 30 cannot be dried, and the broadcast content of the animation is transmitted to the storage unit 400. Temporarily store (S320).

Subsequently, when an object is no longer detected within a corresponding distance with respect to an object located within a corresponding distance detected by the sensor unit 200, or an object located within a corresponding area detected by the sensor unit 200 With respect to, when the movement of the object is no longer detected in the corresponding area, the control unit 700 controls the TV 20 on which the guide image is being output or the set-top box 30 connected to the corresponding TV 20 Then, the paused state is released and the broadcast content received through the set-top box 30 is controlled to be output to the TV 20.

At this time, the control unit 700 is temporarily stored (or buffered) in the storage unit 400 (or buffered) broadcast content from the point in time of the pause (or from a specific point in time before the preset time from the point in time of the pause) Broadcasting content) may be controlled to be output through the TV 20.

That is, the control unit 700 controls to output the broadcast content temporarily stored in the storage unit 400 through the TV 20 so that the viewer can continue watching from the image after the paused time. At this time, the control unit 700 temporarily stores real-time broadcast content from the paused time until the channel change is performed on the channel related to the currently displayed broadcast content, and outputs the temporarily stored broadcast content. In addition, when a channel change is performed on a channel related to the currently displayed broadcast content, the controller 700 ends the real-time temporary storage process of the storage 400 for the output broadcast content before changing the channel, and the The broadcast content temporarily stored in the storage 400 may be initialized (or deleted).

For example, when an object located within the first distance sensed by the sensor unit 200 is out of the first distance and the object is no longer detected within the first distance by the sensor unit 200, The control unit 700 controls the set-top box 30 connected to the TV 20, stops output of the first guide image 510 being output through the TV 20 shown in FIG. 5, and As shown in Fig. 6, the small bus Tayo animation 610 received through the set-top box 30 in real time is controlled to be output from the TV 20.

As another example, an object located within the corresponding second area sensed by the sensor unit 200 is out of the corresponding second area, and the motion of the object is no longer detected by the sensor unit 200 within the second area. When not, the control unit 700 controls the set-top box 30 connected to the TV 20 to stop the output of the second guide image being output through the TV 20, and the storage unit 400 The TV 20 controls to output the broadcast content (for example, the animation that has been temporarily stored since the third time cannot be stopped) before the stop point of the corresponding broadcast content temporarily stored in the TV 20 (S330).

As described above, according to an embodiment of the present invention, when a viewer entering a preset distance or area is detected, the output of broadcast content being output from the TV is paused and warning content is output, and the viewer is viewed at the corresponding distance or area When is not detected, the broadcast content temporarily stored during the paused period is output from the broadcast content after the paused time or the real-time broadcast content is output. You don't have to pay attention to it, and you can protect your TV viewing habits and your eyesight.

The above-described contents may be modified and modified without departing from the essential characteristics of the present invention to those skilled in the art to which the present invention pertains.
