Description

Technical Field

[0001] This disclosure generally relates to the field of display control, and more particularly to a method, apparatus, television set, and program product for intelligent display control of a television set. Background Technology

[0002] Currently, with the popularization of smart homes, smart TVs have become the entertainment center of the home. Traditional TV power-on and power-off operations mainly rely on infrared remote controls or physical buttons on the TV itself, which are cumbersome and lack a smart experience. In recent years, although voice control and gesture control solutions have emerged, they still fall short in terms of "seamless interaction." Users expect TVs to be like smartphones, automatically turning on the screen when the user arrives and automatically turning it off when the user leaves, thus achieving true intelligence and energy efficiency. Summary of the Invention

[0003] To overcome the problems existing in related technologies, this disclosure provides a method, device, television set, and program product for intelligent display control of a television set.

[0007] In some embodiments, the first preset condition includes: setting a first time period, continuously acquiring new average signal strength values ​​within the first time period; and determining that the television meets the screen-on condition in response to the new average signal strength values ​​all exceeding the first threshold.

[0008] In some embodiments, the second preset condition includes: setting a second time period, continuously acquiring new average signal strength values ​​during the second time period; and determining that the television meets the screen-off condition in response to the new average signal strength values ​​all being lower than the second threshold.

[0009] In some embodiments, in response to the presence of multiple mobile terminals, signal strength values ​​of Bluetooth broadcast packets corresponding to each of the mobile terminals are obtained, and the largest signal strength value among the signal strength values ​​is taken as the target signal strength value.

[0022] Some embodiments of this disclosure will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. Various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will become readily apparent upon understanding this disclosure. For example, the order of operations described herein is merely illustrative and is not limited to those orders set forth herein, but can be changed as will become readily apparent upon understanding this disclosure, except for operations that must be performed in a particular order. Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted.

[0023] The embodiments described in the following examples of this disclosure are not representative of all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0024] This disclosure provides a method for intelligent display control of a television set, which is used for automatic display control of the television set. By analyzing Bluetooth broadcast packets sent by a user's mobile terminal, it determines whether a user is approaching the television set in the surrounding environment, and then controls the television set to turn on or off.

[0025] In related technologies, television displays are generally controlled through two main methods. One method utilizes infrared human body sensing technology, which is currently the most common automatic screen-on solution. A pyroelectric infrared sensor (PIR, also known as a passive infrared sensor) is installed on the front of the television. When the sensor detects movement of infrared radiation emitted by a human body, it outputs a high-level signal to wake the television. If no movement signal is detected within a certain period, the television automatically goes into sleep mode. The other method utilizes camera visual recognition technology. High-end smart TVs use built-in high-definition cameras and computer vision algorithms to capture images in real time. When a face or human silhouette is detected in the image, the television is turned on; when no face or human silhouette is detected, the television is turned off.

[0026] Of the technologies mentioned above, pyroelectric infrared sensors cannot perform identity recognition. When pets (cats, dogs, etc.) run by, or even a robot vacuum cleaner passes by, it can mistakenly trigger the TV screen to turn on, resulting in energy waste and light pollution at night. Furthermore, PIR sensors require the user to be facing the sensor directly; if the user is sitting still on the sofa, it can easily be misinterpreted as leaving, causing the TV screen to turn off. Using camera-based visual recognition technology is expensive, requires a high-performance processor to support real-time image analysis, and due to concerns about privacy risks, user acceptance is generally low.

[0027] In view of this, some embodiments of this disclosure provide a method for intelligent display control of a television set, which analyzes Bluetooth broadcast packets sent by a mobile terminal to determine whether a user is approaching in the environment surrounding the television set, and then intelligently controls the television set to turn on or off.

[0028] The intelligent display control method for a television set in this embodiment is implemented through an intelligent display control system for a television set, which includes a television set and a mobile terminal. The mobile terminal is carried by the user and can be a smartphone or wearable device. The mobile terminal has a built-in Bluetooth Low Energy module and, after installing a corresponding application (APP) or registering at the system layer, can continuously send Bluetooth broadcast packets. Each Bluetooth broadcast packet contains a corresponding specific identifier, which includes, but is not limited to, a Bluetooth Media Access Control Address (MAC) address, a fixed token generated by the application, or an encrypted device signature, preferably a Bluetooth MAC address, used to uniquely identify the mobile terminal device. The mobile terminal continuously broadcasts signals to the surrounding environment at fixed intervals using Bluetooth Low Energy technology, ensuring that the television set can continuously receive location information from the user.

[0029] The television, as the core control device of the system, has a built-in Bluetooth communication module that runs scanning and control algorithms. The television is used to acquire Bluetooth broadcast packets sent by mobile terminals. In standby mode, its Bluetooth communication module continuously scans for nearby Bluetooth broadcast packets in Bluetooth Low Energy (BLE) scan mode. When the television captures a Bluetooth broadcast packet, it first parses the specific identifier contained within it, and then matches this identifier with a pre-stored trusted whitelist. The trusted whitelist contains the Bluetooth MAC addresses of user-authorized mobile terminal devices; only devices on the trusted whitelist can trigger the television's display control functions.

[0030] Once the television detects a matching identifier, it acquires the average signal strength of a preset number of matching Bluetooth broadcast packets. This average signal strength represents the distance between the user and the television; a stronger signal (higher average signal strength) indicates a closer user to the television, while a weaker signal (lower average signal strength) indicates a farther user. The television controls its display state based on preset conditions met by the average signal strength. The display state includes either a screen-on or screen-off state. When the television is in a screen-off state, the average signal strength determines whether the television remains on or turns on; conversely, when the television is in a screen-on state, the average signal strength determines whether the television remains on or turns off.

[0031] The intelligent display control system for televisions in this embodiment achieves precise "screen on when someone approaches, screen off when someone leaves" functionality through changes in Bluetooth signal strength. Utilizing the existing Bluetooth hardware of the television and mobile terminal, intelligent display control of the television can be achieved through a pure software upgrade without the need for additional sensor devices. Furthermore, the system determines distance solely based on wireless signal strength, completely avoiding image acquisition and voice monitoring, thus protecting user privacy.

[0032] Figure 1 This is a flowchart illustrating a smart display control method 100 for a television set according to some embodiments of this disclosure, such as... Figure 1 As shown, the method 100 includes S102, S104 and S106.

[0033] In S102, multiple Bluetooth broadcast packets sent by the mobile terminal are obtained, wherein each Bluetooth broadcast packet contains a specific identifier corresponding to the mobile terminal.

[0034] In this embodiment, the mobile terminal can be a smartphone or wearable device, etc. The mobile terminal has a built-in Bluetooth Low Energy module. After the Bluetooth module has a companion app installed or is registered at the system level, it can continuously send Bluetooth broadcast packets. Each Bluetooth broadcast packet contains a corresponding unique identifier, which is used to uniquely identify the mobile terminal device. That is, each Bluetooth broadcast packet sent by the same mobile terminal contains a unique unique identifier, and different mobile terminals have different unique identifiers. This unique identifier includes, but is not limited to, a Bluetooth MAC address, a fixed token generated by an application, or an encrypted device signature, preferably a Bluetooth MAC address, used to uniquely identify the mobile terminal device. The mobile terminal continuously broadcasts signals to the surrounding environment at fixed intervals using Bluetooth Low Energy technology, ensuring that the television can continuously receive location information from the user. The mobile terminal can also be referred to as the broadcasting end.

[0035] As the core control device of the system, the television has a built-in Bluetooth communication module. In standby mode, it runs scanning and control algorithms by enabling BLE scanning mode, continuously scanning for surrounding Bluetooth broadcast packets, and periodically acquiring Bluetooth broadcast packets sent by mobile terminals.

[0036] In S104, in response to the specific identifier contained in a preset number of Bluetooth broadcast packets in a plurality of Bluetooth broadcast packets being matched with the trust whitelist of the TV, the average signal strength of the preset number of Bluetooth broadcast packets is obtained, wherein the average signal strength is used to characterize the distance between the user and the TV.

[0037] In S106, in response to the average signal strength meeting a preset condition, the display state of the television is controlled, wherein the display state is either a screen-on state or a screen-off state.

[0038] In this embodiment, when the television captures a Bluetooth broadcast packet, it matches the captured packet with a pre-stored trusted whitelist. If the match is successful, it indicates that the mobile terminal sending the Bluetooth broadcast packet is a device in the television's trusted whitelist. The trusted whitelist contains the Bluetooth MAC addresses of user-authorized mobile terminal devices; only devices in the trusted whitelist can trigger the television's display control functions.

[0039] Once the television detects a matching identifier, it acquires the average signal strength of a preset number of matching Bluetooth broadcast packets. Since the mobile terminal is carried by the user, the average signal strength can be used to characterize the distance between the user and the television; a stronger signal strength indicates that the user is closer to the television, and a weaker signal strength indicates that the user is farther away from the television.

[0040] This disclosure achieves a precise "screen on when someone approaches, screen off when someone leaves" function without increasing additional hardware costs and fully protecting user privacy. It determines the distance between the user and the TV solely based on the average signal strength of Bluetooth broadcast packets, i.e., the wireless signal strength, without involving image acquisition or voice monitoring. It possesses identification capabilities, only turning on the screen when a whitelisted home device approaches, avoiding false triggering caused by pet movement or other interference.

[0041] Figure 2 This is a flowchart of a method 200 for obtaining the average signal strength according to some embodiments of the present disclosure, such as... Figure 2 As shown, the method includes steps S202, S204, S206, and S208.

[0042] In S202, the acquired Bluetooth broadcast packet is parsed to obtain the specific identifier contained in the Bluetooth broadcast packet.

[0043] In S204, a specific identifier is matched against a pre-entered identifier in the television’s trusted whitelist.

[0044] Figure 3 This is a schematic diagram illustrating the execution process of intelligent display control of a television set according to some embodiments of this disclosure, in conjunction with... Figure 3 As shown in this embodiment, in S302, the television is in standby mode, which can be either screen-on or screen-off. In S304, the television's Bluetooth communication module activates BLE scanning mode to continuously acquire multiple Bluetooth broadcast packets sent by the mobile terminal. Each Bluetooth broadcast packet contains a specific identifier for the corresponding mobile terminal, which can be the Bluetooth MAC address of the mobile device. When a Bluetooth broadcast packet is captured, it is processed immediately. The television parses the Bluetooth broadcast packet according to the Bluetooth protocol specification. For example, if the specific identifier Bluetooth MAC address contained in the Bluetooth broadcast packet is parsed as "AA:BB:CC", then "AA:BB:CC" can uniquely identify the mobile terminal that sent the Bluetooth broadcast packet. Users can pre-enter the unique device identification information of their mobile terminal, i.e., the specific identifier, into the television's trusted whitelist through manual pairing, television boot process, companion application, or near-field wireless communication. For example, the trusted whitelist could be ["AA:BB:CC", "11:22:33", "DD:EE:FF", "44:55:66"]. In step S306, it is determined whether the packet matches the trusted whitelist. The parsed specific identifier is matched against pre-entered identifiers in the TV's trusted whitelist, and the matching result is recorded. If the Bluetooth MAC address "AA:BB:CC" of the parsed Bluetooth broadcast packet exists in the TV's trusted whitelist, the match is successful. The mobile terminal uniquely identified by the Bluetooth MAC address "AA:BB:CC" is a user-authorized mobile terminal entered into the trusted whitelist. If the Bluetooth MAC address of the parsed Bluetooth broadcast packet is not included in the trusted whitelist, the match fails. In this case, the mobile terminal that sent the Bluetooth broadcast packet is not a user-authorized mobile terminal, and step S308 is executed. The Bluetooth broadcast packet is invalid and discarded without further processing.

[0045] In S206, the above process is executed sequentially. In response to the number of successfully matched specific identifiers reaching a preset number, the target signal strength values ​​of the Bluetooth broadcast packets corresponding to the matched specific identifiers are obtained.

[0046] In S208, the signal strength values ​​of each target are smoothed using a Kalman filter algorithm or a weighted moving average algorithm to obtain the average signal strength.

[0047] In this embodiment of the disclosure, a preset number of successfully matched specific identifiers are obtained, such as 10. When 10 successfully matched specific identifiers are obtained, the Received Signal Strength Indicator (RSSI) of each Bluetooth broadcast packet corresponding to the matched specific identifier is obtained through the Bluetooth communication module of the television. This RSSI can be referred to as the target signal strength value. Specifically, the signal strength of the Bluetooth broadcast packet is automatically measured by the radio frequency front-end of the Bluetooth chip built into the Bluetooth communication module. This strength value is an analog quantity, which is converted into a digital value, i.e., RSSI, in dBm. (See also...) Figure 3 As shown, in S310, the raw RSSI value is extracted.

[0048] Because Bluetooth signals fluctuate significantly due to multipath effects, the television uses Kalman filtering or a weighted moving average algorithm to process the continuously acquired target signal strength values, smoothing the most recent N sampling points. For example, the RSSI of the 10 Bluetooth broadcast packets corresponding to the specific identifier is smoothed to generate a stable mean signal strength value, RSSI_AVG. Figure 3 In step S312, smoothing is performed to obtain RSSI_AVG. Smoothing effectively eliminates interference from signal fluctuations in distance determination. In this embodiment, the RSSI value is used to indirectly and trend-wise determine the "distance" between the user and the television.

[0049] In this embodiment of the disclosure, the display state of the television is controlled based on whether the average signal strength obtained above meets the preset conditions.

[0050] In this embodiment of the disclosure, the television is equipped with two different thresholds: a first threshold and a second threshold. The first threshold is also called the wake-up threshold, and the second threshold is also called the leave threshold, wherein the first threshold is greater than the second threshold. The interval between the first threshold and the second threshold is a hysteresis interval.

[0051] The specific control logic is as follows: for example, setting the wake-up threshold to -60dBm and the departure threshold to -80dBm. (Refer to [reference] again.) Figure 3As shown, in S314, the screen state detection logic is entered, and S316 is executed to determine whether the average signal strength exceeds the wake-up threshold. If the average signal strength is greater than the wake-up threshold - 60dBm, the TV is controlled to display a bright screen state when the first preset condition is met. The first preset condition is specifically: in S318, the wake-up anti-shake timer is started, a first time period is set, and new average signal strength values ​​are continuously acquired within the first time period. For example, if the first time period is set to 10 seconds, 5 new average signal strength values ​​are acquired again within the 10-second countdown. The new average signal strength values ​​in this embodiment can be understood as being acquired in a rolling manner. For example, in the process of matching the trusted whitelist, for the RSSI values ​​of the Bluetooth broadcast packets corresponding to the first 10 matching specific identifiers, their RSSI_AVG values ​​are acquired. As the matching in the trusted whitelist continues, new RSSI_AVG values ​​of the RSSI values ​​of the 2nd to 11th matching Bluetooth broadcast packets are acquired, and new RSSI_AVG values ​​of the RSSI values ​​of the 3rd to 12th matching Bluetooth broadcast packets are acquired again. Similarly, new RSSI_AVG values ​​are acquired in a rolling manner during the countdown of the first time period. In S320, it is determined whether the new RSSI_AVG values ​​exceed the wake-up threshold within the first time period. If the new RSSI_AVG values ​​continuously exceed the wake-up threshold -60dBm within the first 10 seconds of the first time period, it is determined that the user has approached the TV, and S322 is executed to send and execute a screen-on command, causing the TV to enter the screen-on state. If not all new RSSI_AVG values ​​exceed the wake-up threshold within the first 10 seconds of the first time period, S314 is executed again, and the screen state detection logic is entered again.

[0052] If the average signal strength in S316 does not exceed the wake-up threshold, then S324 is executed to determine whether the average signal strength is lower than the departure threshold. In S324, if the average signal strength is lower than the departure threshold -80dBm, the TV is controlled to enter a screen-off state when the second preset condition is met. The second preset condition is as follows: In S326, a departure timer is started, a second time period is set, and new average signal strength values ​​are continuously acquired within the second time period. For example, if the second time period is set to 30 seconds, 15 new average signal strength values ​​are acquired within the 30-second countdown. In S328, it is determined whether the new RSSI_AVG value is lower than the departure threshold within the second time period. If the new RSSI_AVG value remains lower than the departure threshold -80dBm within the 30-second second time period, it is determined that the user has left, and S330 is executed to send and execute a screen-off command, causing the TV to enter a screen-off state. If the new RSSI_AVG values ​​are not all below the exit threshold within the second 30-second time period, then S314 is executed again, and the screen state detection logic is entered again.

[0053] In step S324, if the average signal strength is not lower than the off-field threshold, it can be determined that the average signal strength is between the off-field threshold and the wake-up threshold, i.e., within the hysteresis range, for example, an average signal strength of -70dBm. At this point, step S332 is executed, and the television maintains its current display state.

[0054] This embodiment effectively solves the problem of repeated screen flickering caused by signal fluctuations at critical distances by combining a hysteresis comparison algorithm and a smoothing filtering algorithm. For example, it avoids accidental triggering caused by users shaking their mobile terminals while leaning forward or backward on a sofa, thus improving system stability and user experience. In this embodiment, after the TV screen is on or off, Bluetooth broadcast packets sent by the mobile terminal are continuously captured, and the TV display status is continuously and intelligently controlled.

[0055] In this embodiment of the disclosure, when multiple users are simultaneously in the vicinity of the television, the television periodically captures Bluetooth broadcast packets sent by multiple mobile terminals through BLE scanning mode, i.e., multiple Bluetooth broadcast packets are acquired each time. By parsing the multiple Bluetooth broadcast packets and matching them with a trusted whitelist, Bluetooth broadcast packets that fail to match are discarded. The signal strength values ​​of the Bluetooth broadcast packets corresponding to each successfully matched mobile terminal are obtained, and the largest signal strength value among these is taken as the target signal strength value. For example, if the multiple Bluetooth broadcast packets corresponding to the multiple mobile terminals are M1, M2, N1, M3, and M4, after matching with the trusted whitelist, N1 is discarded, and the Bluetooth broadcast packets corresponding to the matched specific identifiers are M1, M2, M3, and M4, their respective signal strength values ​​RSSI1, RSSI2, RSSI3, and RSSI4 are obtained. If RSSI1 is the largest, then RSSI1 is taken as the RSSI value of the multiple Bluetooth broadcast packets acquired this time, i.e., the target signal strength value, as the basis for system determination. In the same manner, the target signal strength values ​​of multiple Bluetooth broadcast packets acquired each time are obtained sequentially, and the average signal strength RSSI_AVG is obtained using the aforementioned method.

[0056] This multi-user weighted logic ensures that when multiple whitelisted devices are detected online simultaneously, the maximum RSSI value among all devices is used as the system's decision criterion. This ensures that the TV remains on even if only one person's location meets the screen-on condition.

[0057] Compared to related technologies, this disclosure utilizes existing Bluetooth hardware in televisions and mobile terminals, eliminating the need to purchase and install expensive PIR sensors or cameras. It can be implemented through a pure software upgrade, significantly reducing hardware costs compared to camera-based visual recognition technology. Relying solely on wireless signal strength to determine distance, it completely eliminates image acquisition and voice monitoring, thus completely removing user privacy concerns and resolving the privacy leakage issues of camera-based visual recognition technology. This disclosure effectively solves the screen flickering problem caused by signal fluctuations at critical distances through hysteresis threshold design, avoiding the problem of infrared human body sensing technology mistakenly interpreting a stationary user as having left and turning off the screen. Furthermore, the screen only lights up when a whitelisted family member approaches, avoiding false triggers caused by pets moving or robot vacuums passing by. It is more intelligent than PIR sensors and solves the problem of infrared human body sensing technology's inability to perform identity recognition.

[0058] Based on the same concept, this disclosure also provides a smart display control device 400 for a television. It is understood that the smart display control device 400 provided in this disclosure includes hardware structures and / or software modules corresponding to each function in order to achieve the above-mentioned functions.
