Description

Technical Field

[0001] The present invention relates to the technical field of television remote control communication, and in particular to a pointing remote control method, a pointing remote control system and a computer-readable medium for a smart television. Background Art

[0002] In the technology related to smart TVs, the Bluetooth connection between the remote control device and the smart TV is generally a one-to-one relationship, and a remote control device cannot maintain a Bluetooth connection with two or more smart TVs at the same time. In some scenarios, if you want to use the same remote control device to switch to control different smart TVs, you need to re-pair the Bluetooth with the smart TV. Repeated pairing is not only cumbersome but also time-consuming. For example, in a smart TV sales mall, shopping guides need to demonstrate smart TV products of different models or sizes to customers in a short period of time. There are differences between TV models and sizes. During the demonstration, the remote control device needs to be re-paired frequently before switching to the target control device.

[0003] Pointing remote control technology uses a combination of gyroscopes and ultra-wideband radio electromagnetic wave technology to accurately locate, realize finger pressing, sliding, long pressing and other operations on large-screen devices, and obtain a precise touch experience. The combination of these technologies allows users to accurately and without delay control of smart TVs. For example, the patent document with patent number 202010365011.5 discloses a pointing remote control system, which can identify the pointing position of the remote control device on the smart TV through the infrared signal sent by the remote control device to control the smart TV; in an environment where multiple devices coexist, the pointing remote control technology can distinguish which device the input remote control signal is for, thereby improving the accuracy and convenience of the operation; however, due to the convenient switching of pointing remote control and the fast switching speed, the connection rate between the remote control and the target control device is required to be higher. When switching to control different smart TV products, the current remote control device needs to frequently re-pair Bluetooth and constantly manually switch the target control device, which has the problem of cumbersome operation and inability to quickly determine the target control device. Summary of the invention

[0004] The purpose of the present invention is to provide a pointing remote control method, a pointing remote control system and a computer-readable medium for a smart TV, with the Bluetooth remote control device in the prior art requiring frequent Bluetooth re-pairing when switching to control different smart TV products, resulting in cumbersome operations and an inability to quickly determine the target control device.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is:

[0006] The pointing remote control method of a smart TV comprises the following steps:

[0007] S1, after the remote control device and the smart TV complete the initial Bluetooth pairing and the first communication connection, determine whether the pointing switch of the smart TV is turned on;

[0008] S2. If the pointing switch is on, setting a target communication address for the second communication, and initiating a connection for the second communication to the smart TV according to the target communication address;

[0009] S3. When the second communication connection is successful, obtaining the direction information of the smart TV;

[0010] S4, judging whether the smart TV exists in a device list of the remote control device according to the pointing information;

[0011] S5. If the smart TV exists in the device list, determine whether the remote control device is pointing to the smart TV through the second communication;

[0012] S6. If the remote control device is pointing to the smart TV, determine the corresponding smart TV in the device list as the target control device.

[0013] The pointing remote control method of the smart TV described in the present invention can connect to the smart TV through the second communication and obtain the pointing information of the smart TV after the remote control device and the smart TV complete the initial Bluetooth pairing and the first communication connection. When the user switches the control of multiple smart TVs, there is no need to re-perform Bluetooth pairing. As long as the pointing switch of the smart TV is turned on, the smart TV and the remote control device can establish a connection through the second communication. If the pointed smart TV is included in the device list, the smart TV in the device list can be quickly determined as the target control device and automatically connected to Bluetooth, effectively avoiding the problem of Bluetooth re-pairing and cumbersome operation between the remote control device and the target control device, ensuring the efficiency of the remote control device pointing to switch the target control device, and also ensuring the accuracy of the remote control device pointing to switch the target smart TV, thereby improving the user experience. When the user does not need to use the pointing remote control function, it only needs to set the pointing switch state of the smart TV to off, which will not affect the remote control function of the ordinary remote control device, thereby improving the convenience of the pointing remote control function control, and also being compatible with the scenario of the remote control device as an ordinary remote control device, thereby broadening the universality of the remote control device.

[0014] Preferably, the pointing remote control method for a smart TV of the present invention, the determining in S5 whether the remote control device is pointing to the smart TV specifically comprises the following steps:

[0015] S51, continuously acquiring relative position data of the smart TV through the second communication; the relative position data includes: a distance between the remote control device and the second communication module of the smart TV, a first horizontal angle, a first pitch angle, a second horizontal angle, and a second pitch angle;

[0016] S52, calculating, based on the relative position data, the intersection of the pointing straight line of the remote control device on the screen of the smart TV, and the horizontal component x and the vertical component y of the distance between the intersection and the second communication module on the screen;

[0017] S53, obtaining the length and width of the screen of the smart TV;

[0018] S54: If the horizontal component x is less than half of the length, and the vertical component y is less than the width, it is determined that the remote control device is pointing to the smart TV.

[0019] As a preferred solution of the present invention, through the above steps S51 to S54, it is possible to more accurately identify and judge whether the remote control device is pointing to the smart TV in the device list, avoid pointing control errors caused by inaccurate pointing judgment, reduce the error rate of the remote control device pointing to control the smart TV, improve the accuracy of the remote control device pointing to remote control, and enhance the user experience.

[0020] Preferably, the pointing remote control method of the smart TV of the present invention further includes the following steps:

[0021] S7, when the user's operation data on the remote control device is obtained, determining whether the first communication between the remote control device and the target control device is in a connected state;

[0022] S8. If the first communication is in a connected state, sending the user operation data in the remote control device to the target control device;

[0023] S9. If the first communication is in an unconnected state, initiating a first communication connection with the target control device;

[0024] S10: If the remote control device is outside the pointing range of the target control device and is not pointing to the smart TV in the device list, the user operation data is not sent to the target control device.

[0025] As a preferred solution of the present invention, on the basis of determining that the smart TV pointed by the remote control device is the target control device, if it is determined that the first communication is in a connected state, operation data can be sent to the target control device through the first communication, and thus there is no need to manually pair the first communication, which facilitates the transmission of operation data and the connection of the first communication, speeds up the response rate of the remote control, and improves the user experience; and, in order to avoid the situation where the user's operation on the remote control device still takes effect on the target control device when the pointing of the remote control device moves out of the effective pointing range of the target control device, through step S10, the user operation data will not be sent to the target control device when the remote control device points to the target control device outside the pointing range, thereby avoiding other controls not intended by the user and improving the safety performance of the pointing remote control.

[0026] Preferably, in the method for pointing remote control of a smart TV of the present invention, the step of determining the target control device in S6 specifically further comprises the following steps:

[0027] S61: If the remote control device simultaneously points to at least two smart TVs arranged along a pointing line, determine a smart TV that is closer to the remote control device as a target control device.

[0028] As a preferred solution of the present invention, when the screen areas of two or more smart TVs are blocked or overlapped, the remote control device may point to two or more smart TVs at the same time. When this happens, the smart TV closest to the remote control device can be determined as the target control device, so that the remote control operation is effective for the smart TV closest to the user, further avoiding control confusion, improving the stability of the use of the pointing remote control function, and enhancing the refined control experience of the pointing remote control.

[0029] Preferably, in the pointing remote control method for a smart TV of the present invention, if the pointed smart TV does not exist in the device list, the step S4 further includes the following steps:

[0030] S41, determining whether the number of smart TVs in the device list exceeds a preset value;

[0031] S42: if the number of smart TVs pointed to does not exceed the preset value, adding the smart TV to the device list;

[0032] S43. If the number exceeds the preset value, the smart TV that is first or most recently added to the device list and whose first communication connection is disconnected is removed from the device list; and the smart TV pointed to is added to the device list.

[0033] As a preferred solution of the present invention, through the above steps S41 to S43, the smart TV can be added to the device list of the remote control device more accurately and orderly, avoiding repeated addition or failure to add smart devices, and further enhancing the stability of the pointing remote control function.

[0034] Preferably, the directional remote control method for a smart TV of the present invention, wherein the target communication address of the second communication is set in S2, specifically comprising the following steps:

[0035] S21, presetting a custom communication address for a second communication match on the remote control device;

[0036] S22, obtaining a peer communication address of the smart TV through the first communication connection;

[0037] S23: Setting the peer communication address as the target communication address of the remote control device.

[0038] As a preferred solution of the present invention, through the communication address setting method of S21 to S23 above, the process of setting the target communication address is simpler and more effective, avoiding the need for both the remote control device and the smart TV to preset custom communication addresses, thereby being able to quickly and conveniently initiate a second communication connection and improve the efficiency of directed remote control.

[0039] Preferably, the directional remote control method for a smart TV of the present invention, the determining in S1 whether the directional switch of the smart TV is turned on or not, specifically comprises the following steps:

[0040] S11, obtaining a first Bluetooth attribute value corresponding to the smart TV; parsing the first Bluetooth attribute value;

[0041] S12: Setting a first Bluetooth attribute value of the smart TV, thereby turning on / off the pointing switch.

[0042] As a preferred solution of the present invention, by obtaining the first Bluetooth attribute value of the smart TV and then obtaining the status value of whether the pointing switch of the smart TV is turned on, the status of the pointing switch can be accurately determined, and then the pointing switch can be turned on or off by setting the first Bluetooth attribute value of the smart TV. When the user wants to add or exit the pointing of the remote control device, the user only needs to turn the pointing switch on or off by setting the interface of the smart TV, thereby improving the convenience of controlling the pointing remote control function.

[0043] Preferably, in the directional remote control method for a smart TV of the present invention, turning on / off the directional switch in S12 specifically comprises the following steps:

[0044] S121. Set the first Bluetooth attribute value by setting system attributes.

[0045] As a preferred solution of the present invention, setting the first Bluetooth attribute value by means of system attributes can ensure that the state value of the pointing switch does not change after the smart TV is restarted, thereby preventing the state of the pointing switch from being turned on or off by mistake and improving the stability of the use of the pointing remote control function.

[0046] To achieve the purpose of the present invention, the present invention also provides a pointing remote control system for a smart TV, comprising: a switch state determination module, a second communication module, a pointing information determination module, a first management module, a remote control pointing determination module, a second management module, a data transmission module and a connection management module;

[0047] The switch state determination module is used to determine the on or off state of the pointing switch; the second communication module is used to perform a second communication with the remote control device; the pointing information determination module is used to obtain the pointing information of the smart TV; the first management module is used to manage the smart TVs in the device list; the remote control pointing determination module is used to determine whether the remote control device is pointing to the smart TV; the second management module is used to determine the target control device; the data transmission module is used to obtain operation data and send the operation data to the smart TV through the first communication; the connection management module is used to manage the first communication connection.

[0048] The pointing remote control system for a smart TV described in the present invention enables the remote control device to determine the pointing switch state of the smart TV and to establish a second communication connection with the smart TV through a plurality of modules respectively arranged in the remote control device and the smart TV. When a user operates the remote control to switch to a smart TV, the pointing information of the pointed smart TV can be obtained, and it can be determined whether the pointed smart TV exists in a device list, so that the smart TV can be determined as a target control device, and the smart TV in the device list can be quickly determined as a target control device. When the user switches control of multiple smart TVs, the user does not need to input information such as the device number of the Bluetooth pairing, and can determine the target control device or automatically connect to the Bluetooth again through the pointing operation, thereby effectively avoiding the problem of re-pairing the remote control device and the target control device with Bluetooth, and improving the user experience.

[0049] To achieve the purpose of the present invention, the present invention also provides a non-temporary computer-readable storage medium on which a computer program is stored. When the computer program is executed by a processor, the pointing remote control method of the smart TV is implemented.

[0050] By configuring or installing the non-temporary computer-readable storage medium described in the present invention, when the computer program is executed, the pointing remote control method of the smart TV described in the present invention can be implemented, thereby achieving the following effects: when the user uses the same remote control device to switch to control different smart TVs, after the initial or preliminary Bluetooth pairing, there is no need to re-pair or manually switch the target control device during the pointing operation, which not only ensures the efficiency of the remote control device pointing to the switching target control device, but also ensures the accuracy of the remote control device pointing to the switching target smart TV, which can help users effectively avoid the problem of repeatedly performing the remote control device re-pairing operation when switching control of multiple smart TVs, thereby improving the user experience.

[0051] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0052] 1. When users switch control of multiple smart TVs, they do not need to manually or re-pair the Bluetooth. They can determine the target control device or automatically connect to the Bluetooth again by pointing, effectively avoiding the cumbersome operation of re-pairing the remote control device and the target control device with Bluetooth;

[0053] 2. During the remote control pointing operation, there is no need to re-pair or manually switch the target control device, which not only ensures the efficiency of the remote control device pointing to switch the target control device, but also ensures the accuracy of the remote control device pointing to switch the target smart TV, thereby improving the user experience.

[0059] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0060] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0061] Embodiment 1:

[0062] like Figures 1 to 3 As shown, the pointing remote control method of the smart TV provided by the present invention comprises the following steps:

[0063] S1, after the remote control device and the smart TV complete the initial Bluetooth pairing and the first communication connection, determine whether the pointing switch of the smart TV is turned on;

[0064] S2. If the pointing switch is on, setting a target communication address for the second communication, and initiating a connection for the second communication to the smart TV according to the target communication address;

[0065] S3. When the second communication connection is successful, obtaining the direction information of the smart TV;

[0066] S4. judging whether the smart TV exists in the device list of the remote control device according to the pointing information;

[0067] S5. If the smart TV exists in the device list, determine whether the remote control device is pointing to the smart TV through the second communication;

[0068] S6. If the remote control device is pointing to the smart TV, the corresponding smart TV in the device list is determined as the target control device.

[0069] It should be noted that the first communication connection described in the present invention is understood to be a Bluetooth connection, and the second communication connection is understood to be an ultra-wideband communication or a star flash communication; the remote control device described in the present invention is a remote control device with a Bluetooth connection function and a second communication connection function, for example, a Bluetooth remote control; the target control device is understood to be a smart TV device to which the remote control device switches to or points.

[0070] Specifically, judging whether the pointing switch of the smart TV is turned on in S1 specifically includes the following steps: S11, obtaining the first Bluetooth attribute value of the corresponding smart TV; parsing the first Bluetooth attribute value; S12, setting the first Bluetooth attribute value of the smart TV, and then turning on / off the pointing switch; More specifically, turning on / off the pointing switch in S12 specifically includes the following steps: S121, setting the first Bluetooth attribute value by setting the system attribute. It should be noted that the first Bluetooth attribute value is understood as the attribute value of the Bluetooth setting containing the value of turning on or off the pointing switch.

[0071] In order to make the process of setting the communication address of the second communication simpler and more effective, and avoid the need for both devices to preset a customized communication address of the second communication, specifically, the method for setting the target communication address of the second communication in S2 specifically includes the following steps: S21, presetting a customized communication address matching the second communication in the remote control device; S22, obtaining the peer communication address of the smart TV through the first communication connection; S23, setting the peer communication address as the target communication address of the remote control device; more specifically, when the pointing switch state of the smart TV is on, the specific method for setting the target communication address is: obtaining the Bluetooth MAC address of the smart TV; setting the Bluetooth MAC address of the smart TV as the target communication address of the second communication.

[0072] It is understandable that after the Bluetooth remote control and the smart TV complete the Bluetooth connection, in order for both parties to communicate using the second communication method, they first need to obtain the communication address of the other party; in the optional scheme, the Bluetooth MAC address is unique. After the Bluetooth remote control and the smart TV complete the Bluetooth connection, both parties can obtain the MAC address of the Bluetooth module connected to it in a universal manner, and directly set the Bluetooth MAC address of the other device as the target communication address of the second communication method. There is no need to obtain the other party's customized second communication method communication address, which simplifies the interaction process.

[0073] It should be noted that the directional information is understood to include but is not limited to the mapping value of the position of the second communication module and the screen size of the smart TV; specifically, refer to Figure 2 As shown, the acquisition of the orientation information of the smart TV in S3 specifically includes the following steps: S31, acquiring the second Bluetooth attribute value of the smart TV; parsing the second Bluetooth attribute value to obtain the second communication module position and screen size of the smart TV. It should be noted that the second Bluetooth attribute value is understood to be a Bluetooth attribute value containing the orientation information of the smart TV, such as the position of the second communication module of the smart TV and the identification value of the screen size.

[0074] Obtain a second Bluetooth attribute value of a preset device; parse the second Bluetooth attribute value to obtain the position of the second communication module of the smart TV and the screen size; it should be noted that the position of the second communication module includes but is not limited to the top center position of the smart TV and the bottom center position of the smart TV, and the screen size of the smart TV includes but is not limited to 55 inches, 65 inches, 75 inches, 85 inches, and 100 inches.

[0075] Specifically, refer to Figure 1 and Figure 3As shown, if the pointed smart TV does not exist in the device list, the S4 also includes the following steps: S41, determine whether the number of smart TVs in the device list exceeds the preset value; S42, if it does not exceed the preset value, add the smart TV to the device list; S43, if it exceeds the preset value, remove the smart TV that was first or most recently added to the device list and whose first communication connection was disconnected from the device list, and then add the pointed smart TV to the device list.

[0076] It is understandable that due to factors such as bandwidth limitations and electromagnetic interference, in order to ensure that the second communication between the Bluetooth remote control and all smart TVs in the device list is connected normally as much as possible, the number of smart TVs already in the device list needs to be limited. When the number of smart TVs already in the device list exceeds the maximum preset value, the first or most recently added smart TV can be removed from the pointing device list.

[0077] It should be noted that the reference Figure 3 As shown, when the state of the pointing switch set by the user changes, for example, if the state of the pointing switch becomes off, it is determined whether the smart TV and the remote control device remain connected. If the second communication remains connected, the second communication connection is actively disconnected first, and then the second communication module of the smart TV is turned off. If the second communication is disconnected, the second communication module is directly turned off; if the state of the pointing switch becomes on, the second communication module of the smart TV is turned on; it can be understood that when the user sets the state of the pointing switch of the smart TV to off, the second communication module can be directly turned off to save power; if the smart TV actively disconnects the second communication connection, the smart TV is removed from the device list, or the smart TV that was first or most recently added to the device list is removed, and then the Bluetooth connection and the second communication connection of the removed smart TV are disconnected.

[0078] Specifically, refer to Figure 2 As shown, the determination in S5 whether the remote control device is pointing to the smart TV specifically includes the following steps:

[0079] S51, continuously acquiring relative position data of the smart TV through the second communication; the relative position data includes: the distance between the remote control device and the second communication module of the smart TV, the first horizontal angle, the first pitch angle, the second horizontal angle, and the second pitch angle;

[0080] S52, extracting information from the relative position data according to a preset rule; calculating, according to the relative position data, the intersection of the pointing straight line of the remote control device on the screen of the smart TV, and the horizontal component x and the vertical component y of the distance between the intersection and the second communication module on the screen;

[0081] S53, obtaining the length and width of the screen of the smart TV;

[0082] S54: If the horizontal component x is less than half of the length, and the vertical component y is less than the width, it is determined that the remote control device is pointing to the smart TV.

[0083] It should be noted that the preset rules are understood as common mathematical algorithms, which can extract relative position data; the first horizontal angle and the first pitch angle are understood as the angles formed by the pointing straight line of the remote control device and the second communication module in the horizontal plane and the vertical plane respectively; the second horizontal angle and the second pitch angle are the angles formed by the pointing straight line of the second communication module and the Bluetooth remote control device in the horizontal plane and the vertical plane respectively.

[0084] When the relative position data of a smart TV in the device list is obtained, illustratively, the distance between the remote control device and the second module is recorded as L according to the preset rule, and the first horizontal angle and the first pitch angle formed by the pointing straight line of the Bluetooth remote control and the second communication module on the horizontal and vertical planes are recorded as ∠a and ∠b, respectively; at the same time, the second horizontal angle and the second pitch angle formed by the pointing straight line of the second communication module and the Bluetooth remote control on the horizontal and vertical planes are recorded as ∠c and ∠d, respectively; then, based on the information in the relative position data, the distance M between the intersection of the pointing straight line of the Bluetooth remote control on the screen of the smart TV and the second communication module is obtained.

[0085] Specifically, the method for obtaining the distance between the intersection of the pointing straight line of the Bluetooth remote control on the smart TV screen and the second communication module of the smart TV is: according to the relative position data, the intersection of the pointing straight line of the Bluetooth remote control on the screen of the smart TV is obtained, and then the horizontal component x and the vertical component y of the distance M between the intersection and the second communication module on the screen of the smart TV are obtained; illustratively, x and y can be obtained by the following formulas 1 and 2, respectively:

[0086] Formula 1: x = (L × sina) / (cos (a + c))

[0087] Formula 2: y = (L × sinb) / (cos (π + db));

[0088] Whether the Bluetooth remote control points to the smart TV is determined based on the distance between the intersection of the pointing straight line of the Bluetooth remote control and the second communication module, the position of the second communication module, and the screen size.

[0089] In this embodiment, as described in steps S53-S54, taking the position of the second communication module as the top center position of the smart TV as an example, a method for determining whether the Bluetooth remote control is pointing to the smart TV is as follows: if the distance x between the intersection on the smart TV screen where the Bluetooth remote control points and the second communication module in the horizontal direction is less than half of the actual length of the smart TV screen; at the same time, if the distance y between the intersection on the smart TV screen where the Bluetooth remote control points and the second communication module in the vertical direction is less than the width of the smart TV screen, it is determined that the Bluetooth remote control is pointing to the smart TV; otherwise, it is determined that the Bluetooth remote control is not pointing to the smart TV.

[0090] Specifically, determining the target control device in S6 further includes the following steps: S61. If the remote control device simultaneously points to at least two smart TVs arranged along a pointing line, determine a smart TV that is closer to the remote control device as the target control device.

[0091] It is understandable that when the screen areas of two or more smart TVs are blocked or overlapped, the Bluetooth remote control may point to two or more smart TVs at the same time. When this happens, the smart TV closest to the Bluetooth remote control can be identified as the target control device, so that the remote control operation of the smart TV closest to the user can take effect, avoiding control confusion and improving the refined control experience of pointed remote control.

[0092] Specifically, refer to Figure 1 As shown, the pointing remote control method of the smart TV also includes the following steps: S7, when the user's operation data on the remote control device is obtained, determine whether the first communication between the remote control device and the target control device is in a connected state; S8, if the first communication is in a connected state, send the user operation data in the remote control device to the target control device; S9, if the first communication is in an unconnected state, initiate a first communication connection with the target control device; S10, if the remote control device is outside the pointing range of the target control device and is not pointing to the smart TV in the device list, do not send the user operation data to the target control device.

[0093] It is understandable that in order to prevent the user's operations on the Bluetooth remote control from still being effective on the target control device when the pointing of the Bluetooth remote control moves out of the effective pointing range of the target control device, the user operations will not be sent to the target control device when the Bluetooth remote control points outside the effective pointing range of the target control device, thereby avoiding control that is not intended by the user and improving the pointing remote control experience.

[0094] Embodiment 2:

[0095] refer to Figure 4As shown, this embodiment provides a pointing remote control system for a smart TV, which is used to implement the pointing remote control method for a smart TV described in Example 1, including: a switch state determination module, a second communication module, a pointing information determination module, a first management module, a remote control pointing determination module, a second management module, a data transmission module and a connection management module;

[0096] The switch state determination module is used to determine whether the pointing switch is on or off; the second communication module is used to perform a second communication with the remote control device; the pointing information determination module is used to obtain the pointing information of the smart TV; the first management module is used to manage the smart TVs in the device list; the remote control pointing determination module is used to determine whether the remote control device is pointing to the smart TV; the second management module is used to determine the target control device; the data transmission module is used to obtain operation data and send the operation data to the smart TV through the first communication; the connection management module is used to manage the first communication connection.

[0097] It should be noted that the data transmission module is not limited to sending operation data to the smart TV, but is also used to obtain the user's operation data on the Bluetooth remote control; the connection management module is used to determine whether the Bluetooth remote control maintains a Bluetooth communication connection with the target control device. When the user's operation data on the Bluetooth remote control is obtained, but the Bluetooth remote control and the target control device do not maintain a Bluetooth communication connection, a Bluetooth connection with the target control device is initiated; the data transmission module includes a sending management submodule, which sends the user's operation data to the target control device when the user's operation data on the Bluetooth remote control is obtained and the Bluetooth remote control and the target control device maintain a Bluetooth communication connection; when the Bluetooth remote control points out of the effective pointing range of the target control device and the Bluetooth remote control does not point to any smart TV in the device list, the user operation data is not sent to the target control device.

[0098] For example, reference Figure 5 As shown, the method for using the pointing remote control system of the smart TV of the present invention specifically includes the following steps: T1. During the use of the smart TV, the state value of the pointing switch set by the user is saved; T2. According to the change of the state value of the pointing switch, the working state of the second communication module of the smart TV is determined; T3. When the remote control device reads the Bluetooth attribute of the pointing switch, the Bluetooth attribute value of the pointing switch is set; T4. After the second communication connection is successful, the Bluetooth attribute value of the smart TV regarding the pointing information is set.

[0099] The state value of the pointing switch of the present invention can be set by the user through the control setting menu switch, or can be set by the user through voice, such as "turn on / off the pointing remote control". When the user or the shopping guide wants to join or exit the pointing remote control system, they only need to control the switch through the setting menu of the smart TV or directly through voice, which improves the convenience of controlling the pointing remote control function;

[0100] Specifically, when the state of the pointing switch set by the user changes and the state of the pointing switch becomes off, it is determined whether the smart TV and the remote control device connected to the Bluetooth maintain a second communication connection. If the second communication connection is maintained, the second communication connection is actively disconnected first, and then the second communication module of the smart TV is turned off; if the second communication connection is not maintained, the second communication module of the smart TV is directly turned off; conversely, when the state of the pointing switch set by the user changes and the state of the pointing switch becomes on, the second communication module of the smart TV is turned on; it can be understood that when the user sets the state of the pointing switch of the smart TV to off, the second communication module can be directly turned off to achieve the purpose of saving power.

[0101] In the present embodiment, a method for controlling a smart TV by pointing a Bluetooth remote control is provided. When it is determined that the Bluetooth remote control is pointing to the smart TV, the Bluetooth is automatically connected. This can help users effectively avoid the problem of repeatedly re-pairing the Bluetooth remote controls when switching control of multiple smart TVs, thereby improving the user experience. At the same time, by providing pointing switch state control for the smart TV, the convenience of controlling the pointing remote control function of the smart TV is improved, and the Bluetooth remote control is also compatible with the scenario where the Bluetooth remote control is used as a common remote control device. When the user does not need to use the pointing remote control function, the user only needs to set the pointing switch state of the smart TV to off, which will not affect the remote control function of the common Bluetooth remote control.

[0103] Based on Example 1 or 2, this embodiment discloses a non-temporary computer-readable storage medium on which a computer program is stored. When the computer program is executed by a processor, the pointing remote control method of the smart TV of Example 1 is implemented.

[0104] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
