[0055] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0056] like Figure 1 As shown, a method for managing a TV startup page includes:

[0057] Monitor the power-on signal of the remote control device;

[0058] In response to the power-on signal, obtain the number of people currently watching the TV, and determine whether the number of people watching is greater than one person;

[0059] If not, the identity information of the holder of the remote control device is obtained, and according to the identity information of the holder, a license holder page pre-bound with the identity information of the holder is displayed;

[0060] If so, the identity information of the main person among all the viewers is obtained; according to the identity information of the main person, the license holder page pre-bound with the identity information of the main person is displayed.

[0061] The specific implementation process of this embodiment includes:

[0062] The remote control device includes a smart TV remote control, a TV set-top box remote control or a smart phone; the remote control device is triggered to send a power-on signal to the smart TV or set-top box by long pressing or tapping a button or a screen;

[0063] In this embodiment, multiple licensors are integrated in the smart TV; in some other embodiments, multiple licensors are integrated in the set-top box; the film sources, prices, and UI styles of each licensor are different; individuals have different preferences for different licensors, so it is necessary to directly enter the preferred licensor page after turning on the TV.

[0064] When a power-on signal is received, the number of viewers in front of the TV is obtained. When the number of viewers in front of the TV is 1, the identity information of the holder of the remote control device is directly obtained, and the license holder page pre-bound with the identity information is called up for display when the TV is turned on;

[0065] When the number of viewers is greater than one, the identity information of the viewer in the main seat is obtained from all viewers, and when the TV is turned on, the license owner's page pre-bound with the identity information of the viewer in the main seat is retrieved for display.

[0066] In this embodiment, the smart TV or set-top box is also provided with a built-in system application page; the system application page is provided with a wizard application; the wizard application is used to guide the user to enter identity information and bind the preferred licensee with the identity information.

[0067] It should be noted that if the identity information is not entered or the identity information of the license holder is not bound, the system application page will be displayed when the TV is turned on.

[0068] This embodiment divides the TV viewing situation into two situations: single-person viewing and multi-person viewing by obtaining the number of people in front of the TV when the TV is turned on. When watching by one person, the identity information of the viewing person is directly obtained, and the license owner page bound to the identity information is directly entered when the TV is turned on. When watching by multiple people, the identity information of the main seat person is obtained, and the license owner page is displayed according to the identity information of the main seat person. Regardless of whether the holder of the remote control device is in the main seat, it is convenient to directly display the license owner page preferred by the main seat person after turning on the TV when multiple people are watching, which solves the technical problem in the prior art that the user's preferred license owner page cannot be quickly entered when the smart TV is turned on, and the TV viewing effect is better.

[0069] Another embodiment of the present invention obtains the number of people currently watching the TV, including:

[0070] Get the infrared image in front of the current TV;

[0071] identifying all persons in the infrared image;

[0072] The persons within the viewing range of the TV are marked with viewing person tags, and the viewing person tags are counted to obtain the number of viewers.

[0073] The specific implementation process of this embodiment includes:

[0074] Because when using the TV at home, the indoor lighting is often turned off for a better viewing effect, so in this embodiment, the infrared image in front of the TV is collected, and the number of people watching can still be identified based on the infrared image even when the indoor lighting is insufficient. In this embodiment, the infrared image in front of the TV is collected by an infrared camera set on the TV; in some other embodiments, an infrared camera is set in the set-top box, and the infrared camera is facing the viewing person.

[0075] On the other hand, televisions are mostly placed in living rooms. With the changes and development of residential layout, the scope of living rooms is getting larger and larger. Therefore, if all people in front of the TV are identified to obtain the number of viewers, it will lead to technical inaccuracy. Therefore, in this embodiment, the viewing range of the TV is set; only the people within the viewing range are counted.

[0076] like Figure 5 As shown, one embodiment of the present invention discloses a method for obtaining a viewing range of a television set, comprising:

[0077] The viewing range of the television set includes:

[0078] Obtain the horizontal viewing angle, vertical viewing angle, maximum viewing distance and minimum viewing distance of the display screen according to the parameters of the TV;

[0079] A spatial rectangular coordinate system is established with the center of the display screen of the TV as the origin, the line connecting the midpoints of the upper and lower edges of the display screen as the Y axis, and the normal of the display screen as the Z axis;

[0080] In the spatial rectangular coordinates, the three-dimensional area constructed according to the horizontal viewing angle, the vertical viewing angle, the maximum viewing distance and the minimum viewing distance is the viewing range of the television.

[0081] The parameters of a TV display screen include horizontal viewing angle, vertical viewing angle, maximum viewing distance and minimum viewing distance; the horizontal viewing angle, vertical viewing angle, maximum viewing distance and minimum viewing distance of display screens of different materials, different manufacturers and different models are all different;

[0082] The horizontal viewing angle is the maximum viewing angle on both sides of the horizontal direction. Figure 5 The vertical viewing angle shown in is the maximum viewing angle on both sides in the vertical direction, and the maximum viewing distance includes the farthest distance at which a human eye can clearly see a TV program when watching a TV set;

[0083] When the viewer is outside the maximum viewing distance, the viewing effect is affected; and when the user wants to watch TV, he is within the maximum viewing distance.

[0084] When the display screen is a curved surface, the line connecting the midpoints of its two side edges does not pass through the center of the display screen. In order to increase the applicability of this embodiment, in this embodiment, the center of the display screen of the TV is determined as the origin, the line connecting the midpoints of the upper and lower edges of the display screen is determined as the Y-axis, the normal of the display screen is determined as the Z-axis, and the straight line that is perpendicular to both the Y-axis and the Z-axis and passes through the origin is determined as the X-axis.

[0085] It also includes the minimum viewing distance. When the viewer is too close to the TV, he can only see part of the display screen.

[0086] like Figure 5 As shown in the figure, the fan-shaped area Q1 is obtained according to the horizontal viewing angle and the farthest viewing distance, and the fan-shaped area Q2 is obtained according to the vertical viewing angle and the farthest viewing distance; the part of the fan-shaped area Q1 and the fan-shaped area Q2 within the minimum viewing distance is deleted according to the minimum viewing distance, and the three-dimensional area formed by the combination of the fan-shaped area Q1 and the fan-shaped area Q2 within the minimum viewing distance is the viewing range of the TV. The part within the minimum viewing distance includes the part whose vertical distance to the TV screen is less than the minimum viewing distance.

[0087] like Figure 2 and Figure 4 As shown, in another embodiment of the present invention, obtaining the identity information of the main person includes:

[0088] According to the infrared image marked with the viewing person tag, the viewing person tag located in the projection area of ​​the TV is obtained;

[0089] According to the viewing person tags in the projection area of ​​the TV, the vertical viewing angle and the horizontal viewing angle corresponding to each viewing person tag are obtained;

[0090] Obtain corresponding position scores according to the vertical viewing angle and horizontal viewing angle between the eye and the center of the TV display screen corresponding to each viewer label, and sort them in order of high and low position scores;

[0091] Obtaining the viewing person label with the highest position score as the main label, wherein the main label corresponds to the main person;

[0092] Identify the main person and obtain his / her identity information.

[0093] The specific implementation process of this embodiment includes:

[0094] When watching TV, the viewing effect is best when facing the display screen of the TV. Therefore, the projection area in this embodiment includes: taking the center of the display screen of the TV as the origin, taking the line connecting the midpoints of the upper and lower edges of the display screen as the Y axis, and taking the line connecting the midpoints of the two side edges of the display screen as the X axis, to establish a plane rectangular coordinate system;

[0095] The rectangular area with the origin as the center, the display screen width as the width, and the display screen length as the length is the projection area of ​​the TV.

[0096] The viewing person tag in the projection area obtains the eye projection coordinates of the eyes of the person corresponding to the viewing person tag in the viewing range on the plane rectangular coordinate system;

[0097] Get the label of the person who is viewing the image within the projection area;

[0098] Then, the vertical viewing angle and horizontal viewing angle of all viewers within the projection area are obtained; the vertical viewing angle includes the angle between the eyes of the viewers and the horizontal plane where the center of the display screen is located; the horizontal viewing angle includes the angle between the eyes of the viewers and the normal line of the center of the display screen in the horizontal direction;

[0099] The corresponding position score is obtained according to the vertical viewing angle and the horizontal viewing angle, and the corresponding viewer with the highest position score is taken as the main seat; then, according to the identity information of the viewer in the main seat, the corresponding bound license holder page is displayed.

[0100] It is based on the preferences of the person in the main seat, which is in line with the arrangement of people when multiple people are watching TV; the person with the strongest desire to watch TV will be placed in the main seat.

[0101] In another embodiment of the present invention, the identification of the main person is performed to obtain identity information, including:

[0102] According to the main position label, the human image of the main position person is intercepted in the infrared image;

[0103] Acquire feature data of the human image, wherein the feature data includes a maximum distance between two ears, a head length, a shoulder width, and a neck length;

[0104] Compare the maximum distance between the two ears, the head length, the shoulder width and the neck length in the feature data in the corresponding database; obtain the identity information sets corresponding to the maximum distance between the two ears, the head length, the shoulder width and the neck length respectively;

[0105] Find the intersection of multiple identity information sets corresponding to the maximum distance between the two ears, the length of the head, the width of the shoulders, and the length of the neck;

[0106] The identity information in the intersection is the identity information of the principal.

[0107] The specific implementation process of this embodiment includes:

[0108] In order to protect the privacy of personnel, this embodiment does not collect facial information of personnel; the identity information entered into the database can be identified through multiple sets of data such as the maximum distance between the two ears, the length of the head, the width of the shoulders, and the length of the neck.

[0109] like Figure 4 As shown, in another embodiment of the present invention, obtaining the location score includes:

[0110] Obtaining a difference between a horizontal viewing angle of a viewer and a target horizontal viewing angle as a first deviation;

[0111] acquiring a difference between a vertical viewing angle and a target vertical viewing angle as a second deviation;

[0112] obtaining a difference between a viewing distance of the viewing person and a target distance as a third deviation;

[0113] Substitute the first deviation, the second deviation, and the third deviation into the scoring formula to obtain the position score.

[0114] The specific implementation process of this embodiment includes:

[0115] The scoring formula includes:

[0116] PF=1 / (α 1 *JDC 1 +α 2 *JDC 2 +α 3 *JDC 3 );

[0117] PF is the position score; JDC is 1 is the absolute value of the first deviation; JDC 2 is the absolute value of the second deviation; JDC 3 is the absolute value of the third deviation; α 1 , α 2 and α 2 All are proportional coefficients.

[0118] The target vertical viewing angle and the target vertical viewing angle are both zero degrees. The optimal viewing distance is determined according to the size of the TV. In this embodiment, the optimal viewing distance includes three times the diagonal distance of the LCD TV.

[0119] The higher the location score, the better the location; ideally, JDC 1 is the absolute value of the first deviation; JDC 2 is the absolute value of the second deviation; JDC 3 If the absolute value of the third deviation is 0, the position score is infinite, and the corresponding viewing person label is directly judged as the primary label.

[0120] When there are multiple persons with the highest position scores, the one with the smallest first deviation will be selected as the main person.

[0121] like Figure 3 As shown, another embodiment of the present invention obtains eye projection coordinates, including:

[0122] Obtain the left eye projection coordinates and the right eye projection coordinates of the viewer respectively;

[0123] The coordinates of the midpoint between the left eye and the right eye are used as the eye projection coordinates of the observer.

[0124] In another embodiment of the present invention, obtaining the identity information of the remote control device holder includes:

[0125] The holder triggers the remote control device to send a power-on signal through finger movements, and at the same time, the fingerprint of the finger is collected;

[0126] The fingerprint is compared with the fingerprint database to obtain the identity information of the holder.

[0127] Another embodiment of the present invention, after identifying the identity information of the remote control device holder or the main seat person, further determines whether the identity information of the remote control device holder or the main seat person is pre-bound to the license holder page;

[0128] If not, the system application page is displayed.

[0129] The specific implementation process of this embodiment includes:

[0130] When the identity information of the main person or the remote control device holder is not entered, or the identity information is not pre-bound to the license holder page; the TV is controlled to display the system application page when it is turned on, and the system application page includes the system application page that comes with the smart TV and the system application page in the set-top box.

[0131] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
