Description

Low-power consumption standby method and display device

Technical Field

The application relates to the technical field of display equipment, in particular to a low-power consumption standby method and display equipment.

Background

Currently, more and more display devices (such as televisions) can support far-field voice wakeup functions in standby mode. For example, when the television is in a standby state, the television may detect a voice wake word of a user through a Microphone (MIC) built therein, and when the MIC detects the voice wake word, the television may perform an action corresponding to the voice wake word, so that the television may be switched from the standby state to the on state.

When the display device is in a standby state, the display device can extinguish the screen of the display device, but a system of the display device still operates, so that the far-field voice awakening function can be supported by the display device in the standby state.

However, the display device extinguishes the screen of the display device, but the system of the display device is still running, although the far-field voice wake-up function is supported by enabling the display device in a standby state. However, in the standby state, since the system of the display device is still running, the power consumption of the display device is high.

Currently, more and more display devices (such as televisions) can support far-field voice wakeup functions in standby mode. For example, when the television is in a standby state, the television can detect a voice wake-up word of a user through a Microphone (MIC) built in the television. When the MIC detects a voice wake word, the television may perform an action corresponding to the voice wake word, so that the television may be switched from a standby state to a power-on state.

When the display device is in a standby state, the display device can extinguish the screen of the display device, but the system of the display device is still running (namely, the display device is in a false standby state of a screen-extinguishing mode), so that the far-field voice awakening function can be supported by the display device in the standby state.

That is, in a pseudo standby state (which may also be referred to as a speaker mode) in which the display device is in a screen-off mode, the system on the SOC of the display device is still running, and only the screen of the display device is turned off, so that the far-field voice wake-up function can be supported while the display device is in the standby state, but the power consumption of the display device may reach about 8 watts (watt, W), and the power consumption of the display device is high.

Therefore, the display device extinguishes the screen of the display device, but the system of the display device is still running, although the far-field voice wake-up function can be supported by the display device in a standby state. However, in the standby state, since the system of the display device is still running, the power consumption of the display device is high.

The principles of the related art in the prior art and the above three modes will be schematically described with reference to fig. 1, taking a display device as an example of a television.

As shown in fig. 1, the states of the television include a power-on state, a speaker mode, and an ultra-low power consumption standby state.

The starting state is that the SOC of the television is in a full-speed running state, that is, the frequency of a central processing unit (central processing unit, CPU) in the SOC of the television is in the highest frequency, all cores of the CPU are in a running state, and the memory of the television is in a full-use state. When the television is in a starting state, the display screen of the television is in a non-extinguishing state (namely, the display screen is in a display state and can display corresponding contents), and the system of the television is in an operating state. When the television is in a starting state, because the SOC of the television is in a full-speed running state, the power consumption of the television is full-speed power consumption, and the power consumption of the television is highest at the moment.

The sound box mode (namely the false standby state of the screen-off mode) is that the SOC of the television is in a full-speed running state, namely the frequency of the CPU in the SOC of the television is at the highest frequency, all the cores of the CPU are in a running state, and the memory of the television is in a full-use state. When the television is in the sound box mode, the display screen of the television is in an off state (namely, the display screen is in a non-display state and cannot display corresponding contents), and the system of the television is in an operation state. When the television is in the sound box mode, since the SOC of the television is in a full-speed running state and the display screen is in a turned-off state, the power consumption of the television is the power consumption of the turned-on state minus the power consumption required by the screen (i.e., the display screen), and the power consumption of the television is the next highest (i.e., less than the power consumption in the turned-on state), which is usually 8W.

The ultra-low power consumption standby state, i.e. the SOC of the television is in a completely frozen state (i.e. a freeze state), i.e. the CPU and the memory in the SOC of the television may be in a sleep or low power consumption state. When the television is in the ultra-low power consumption standby state, the display screen of the television is in an off state, and the system of the television is in a non-running state. When the television is in the ultra-low power consumption standby state, the power consumption of the television is lowest because the system of the television is in a non-running state and the display screen is in an off state.

As shown in fig. 1, when the state of the television is in a power-on state and the speaker mode switch of the television is in a power-on state, a user can power off the television through remote control or voice corresponding to the television, so that the television can enter the speaker mode. After the television enters the sound box mode, a user can start up through a remote control or voice instruction corresponding to the television, so that the television can enter a starting-up state.

When the state of the television is in a starting state and the standby wakeup switch of the television is in a closing state, a user can shut down the television through remote control or voice corresponding to the television, so that the television can enter an ultralow-power-consumption standby state. After the television enters the ultra-low power consumption standby state, a user can start up through a remote control corresponding to the television, so that the television can enter the starting-up state.

As can be seen from the principle of the prior art shown in fig. 1, the power consumption of the television in the idle mode (i.e. the speaker mode) is smaller than the power consumption of the television in the above-mentioned power-on state, i.e. the power consumption of the television in the idle mode is the power consumption of the display device in the power-on state minus the power consumption required by the screen. However, the power consumption of the television in the pseudo standby state of the off screen mode is usually 8W, and still higher.

In the related art, in order to avoid higher power consumption of the display device in the standby state, the power consumption of the display device in the standby state can be reduced by the following three ways. Since the power consumption of the display device in the standby state can be reduced in the following three modes, the standby state of the television in the following three modes may also be referred to as an ultra-low power consumption standby state.

The first approach is based on standby of the digital signal processor (digital signal processing, DSP). I.e. a powerful DSP that is externally attached to the system on a chip (SOC) of the display device itself, i.e. the ability to process information. The DSP is specially used for realizing a far-field voice wake-up function in a standby state of the display equipment. After the standby wakeup of the display device is successful, namely, the DSP detects a voice wakeup word of a user through a microphone of the display device, and the DSP can pull up the SOC of the display device to start.

According to the first mode, the DSP is specially used for realizing the far-field voice awakening function of the display equipment in the standby state, so that the far-field voice awakening function of the display equipment in the standby state can be ensured. In the standby state, the system of the display device is not required to be in an operation state, and the power consumption of the display device is about 2W, namely in the first mode, the power consumption of the display device can be reduced in the standby state.

However, in this first mode, a powerful DSP is externally hung outside the SOC of the display device itself, resulting in higher cost of the display device.

The second approach is based on standby of a low cost microprocessor (microcontroller unit, MCU). Namely, a MCU with lower calculation force is hung outside the SOC of the display device. The MCU is specially used for realizing a far-field voice wake-up function in a standby state of the display equipment. After the standby wakeup of the display device is successful, namely, the MCU detects a voice wakeup word of a user through a microphone of the display device, and the MCU can pull up the SOC of the display device to start.

In the second mode, the MCU with low cost is specially used for realizing the far-field voice awakening function of the display equipment in the standby state, so that the far-field voice awakening function of the display equipment in the standby state can be ensured. In the standby state, the system of the display device does not need to be in an operation state, and because the power of the MCU is low, the power consumption of the display device is about 0.5W, namely in the second mode, the power consumption of the display device can be reduced in the standby state.

However, in this second method, a low-cost MCU is hung outside the SOC of the display device itself, but the cost of the display device is high. In addition, in the second mode, the power of the MCU is low, so the corresponding performance is relatively poor, and the false wake-up rate of the display device in the standby state is high.

The third way is based on the way of the secondary check. Namely, a MCU with lower calculation force is hung outside the SOC of the display device. The MCU is specially used for realizing a far-field voice wake-up function of the display equipment in a standby state, and the screen of the display equipment is extinguished when the display equipment is in the standby state. After the standby wakeup of the display device is successful, that is, the MCU detects the voice wakeup word of the user through the microphone of the display device, the MCU informs the system of the display device. The system of the display device performs secondary verification on the voice wake-up word of the user, so that when the verification is successful, the system of the display device enables the display device to be started.

In the third mode, the low-cost MCU is specially used for realizing the far-field voice wake-up function in the standby state of the display equipment, so that the cost of the display equipment can be reduced. In addition, the system of the display device is not required to be in an operation state in the standby state, so that the power consumption of the display device can be reduced in the standby state in the third mode.

In addition, in the third mode, because secondary verification is needed, real-time response cannot be achieved, and about 3-5S time is needed, the display device can be started, and therefore the use experience of a user is poor.

It can be seen that the above three related techniques do not solve the above problem well, i.e. how to avoid that the power consumption of the display device is high in the standby state.

In view of the above problems, embodiments of the present application provide a low power consumption standby method, which is applied to a display device. When the standby wake-up switch of the display device is in an on state and a power-off operation (such as a standby instruction input by a user) of the user is received, the display device can be adjusted to a wakeable standby state (in the embodiment of the application, the wakeable standby state may also be referred to as a low-power consumption standby wake-up state), and in the wakeable standby state, the power resource of the SOC of the display device is adjusted to a power resource capable of supporting only the far-field voice wake-up function, so that the far-field voice wake-up function is supported in the standby state of the display device.

According to the scheme, when the display equipment is in the awakenable standby state, the computing power resource of the SOC of the display equipment is adjusted, and additional DSP or MCU is not required to be added, so that the cost of the display equipment can be reduced by the scheme. In addition, according to the scheme, the power calculation resource of the SOC of the display equipment is adjusted to the power calculation resource which can only support the far-field voice awakening function, so that when the display equipment is in a standby state, a system of the display equipment cannot be in an operation state, and power consumption of the display equipment in the standby state can be reduced.

The low power consumption standby method provided by the embodiment of the application is described below.

The principle of the low power standby method provided in the embodiment of the present application will be schematically described with reference to fig. 2, taking a display device as an example of a television.

As shown in fig. 2, the states of the television set include a power on state, a speaker mode, an ultra-low power standby state, and a wakeable standby state (i.e., a low power standby wake state).

The starting state is that the SOC of the television is in a full-speed running state, that is, the frequency of a CPU in the SOC of the television is in the highest frequency, all cores of the CPU are in a running state, and the memory of the television is in a full-use state. When the television is in a starting state, the display screen of the television is in a non-extinguishing state, and the system of the television is in an operating state. When the television is in a starting state, because the SOC of the television is in a full-speed running state, the power consumption of the television is full-speed power consumption, and the power consumption of the television is highest at the moment.

The sound box mode, namely the SOC of the television is in a full-speed running state, namely the frequency of the CPU in the SOC of the television is at the highest frequency, and the memory of the television is in a full-use state. When the television is in the sound box mode, the display screen of the television is in an off state, and the system of the television is in an operating state. When the television is in the sound box mode, because the SOC of the television is in a full-speed running state and the display screen is in a blanking state, the power consumption of the television is the power consumption of the starting state minus the power consumption required by the screen, and the power consumption of the television is the next highest.

The awaking standby state (may also be referred to as a low power consumption standby awaking state in the embodiment of the present application) that is, the SOC of the television is configured as a SOC single-core small-memory configuration, a freeze mode, and a wake-up voice activation detection (voice active detection, VAD) function is in an operation state. That is, in the wakeable standby state, only one core of the plurality of cores included in the SOC of the television is in an operating state, and the frequency of the core and the memory in the SOC of the television are configured to be able to satisfy the frequency of the VAD function and the corresponding memory. In the wakeable standby state, other cores included in the television CPU are in a non-running state, such as the frequency of the other cores is zero. In the state of awaking standby, the memory in the SOC of the television is in a non-use state (in the embodiment of the present application, the non-use state may also be referred to as a sleep state) except that the memory corresponding to the VAD function is in a use state.

In the wake-up standby state, since only one core of the CPU of the SOC of the television is in an operating state, the frequency of the core is not the highest frequency, but can meet the frequency of the VAD function, and the memory in the SOC of the television is in a non-use state except the memory corresponding to the VAD function. Therefore, in the awakenable standby state, the power consumption of the television is single-core low-speed power consumption, and the power consumption is low. That is, in the wakeable standby state, the power consumption of the television is smaller than the power consumption of the television in the on state, smaller than the power consumption of the television in the speaker mode, and larger than the power consumption of the television in the ultra-low power consumption standby state.

As shown in fig. 2, when the state of the television is in a power-on state and the speaker mode switch of the television is in a power-on state, a user can power off the television through a remote control or voice corresponding to the television, so that the television can enter the speaker mode. After the television enters the sound box mode, a user can start up through a remote control or voice instruction corresponding to the television, so that the television can enter a starting-up state. After the television enters the sound box mode, the user starts up through voice, so that the television enters a starting-up state, namely the television supports a far-field voice awakening function.

When the state of the television is in a starting state and the standby awakening switch of the television is in an on state, a user can shut down the television through a remote control or voice corresponding to the television, so that the television can enter the awakenable standby state. After the television enters the awakenable standby state, a user can start up through a remote control or voice corresponding to the television, so that the television can enter the starting-up state. After the television enters the awakenable standby state, the user starts up through voice, so that the television enters the starting-up state, namely the television supports the far-field voice awakening function.

That is, when the state of the television is in a power-on state and the standby wake-up switch of the television is in an on state, and the user turns off the television through the remote control or voice corresponding to the television, the television can enter the wake-up standby state. That is, the television may adjust the computing power resource of the SOC of the television itself to be a computing power resource capable of supporting only the far-field voice wake-up function, that is, only one core of the cores included in the CPU in the SOC of the television is in an operating state, and the frequency of the core and the memory in the SOC of the television are configured to be capable of satisfying the frequency of the VAD function and the corresponding memory (that is, the computing power resource capable of supporting only the far-field voice wake-up function). Therefore, the far-field voice wake-up function can be supported under the condition that the display equipment is in a standby state.

When the television is in a wakeable standby state, the computing power resource of the SOC of the television is adjusted, and no additional DSP or MCU is needed, so that the cost of the display equipment can be reduced. And in the state that the television is in the awakenable standby state, the computing power resource of the SOC of the television is adjusted to be the computing power resource which can only support the far-field voice awakening function, namely when the television is in the awakenable standby state, the CPU of the SOC of the television is in an operating state, the frequency of the core is not the highest frequency, but can meet the frequency of the VAD function, and the memory in the SOC of the television is in a non-use state except the memory corresponding to the VAD function. Therefore, in the awakenable standby state, the system of the television is not in a complete running state, namely the power consumption of the television is single-core low-speed power consumption, and the power consumption is low. That is, in the wakeable standby state, the power consumption of the television is smaller than the power consumption of the television in the on state, smaller than the power consumption of the television in the speaker mode, and larger than the power consumption of the television in the ultra-low power consumption standby state.

The display device provided by the embodiment of the application can have various implementation forms, for example, can be a display device with far-field voice wake-up function such as a television, an intelligent television, a laser projection device, a display (monitor), an electronic whiteboard (electronic bulletin board), an electronic desktop (electronic table) and the like.

As shown in fig. 4, the control device 200 includes a controller 210, a communication interface 230, a user input/output interface 240, a memory, and a power supply. The control apparatus 200 may receive an input operation instruction of a user and convert the operation instruction into an instruction recognizable and responsive to the display device 300, and may function as an interaction between the user and the display device 300.

By way of example, taking a display device as a television, fig. 5 shows a schematic structural diagram of a display device according to an embodiment of the present application.

As shown in fig. 5, the display apparatus 300 includes at least one of a modem 310, a communicator 320, a detector 330, an external device interface 340, a controller 350, a display 360, an audio output interface 370, a touch assembly 380, a memory, a power supply, and a user interface.

In some embodiments the controller includes a processor, a video processor, an audio processor, a graphics processor, RAM, ROM, a first interface for input/output to an nth interface.

The display 360 includes a display screen component for presenting a picture, and a driving component for driving image display, a component for receiving an image signal from the controller output, displaying video content, image content, and a menu manipulation Interface, and a user manipulation User Interface (UI).

The display 360 may be a liquid crystal display, an OLED display, a projection device, and a projection screen.

The communicator 320 is a component for communicating with external devices or servers according to various communication protocol types. For example: the communicator may include at least one of a Wifi module, a bluetooth module, a wired ethernet module, or other network communication protocol chip or a near field communication protocol chip, and an infrared receiver. The display device 300 may establish transmission and reception of control signals and data signals with the external control device 200 or the server 400 through the communicator 320.

The detector 330 is used to collect signals of the external environment or interaction with the outside. For example, the detector 330 includes a light receiver, a sensor for collecting the intensity of ambient light; alternatively, the detector 330 includes an image collector such as a camera, which may be used to collect external environmental scenes, attributes of a user, or user interaction gestures, or alternatively, the detector 330 includes a sound collector such as a microphone, etc. for receiving external sounds.

The external device interface 340 may include, but is not limited to, the following: high Definition Multimedia Interface (HDMI), analog or data high definition component input interface (component), composite video input interface (CVBS), USB input interface (USB), RGB port, or the like. The input/output interface may be a composite input/output interface formed by a plurality of interfaces.

The modem 310 receives broadcast television signals through a wired or wireless reception manner and demodulates audio and video signals, such as EPG data signals, from a plurality of wireless or wired broadcast television signals.

In some embodiments, the controller 350 and the modem 310 may be located in separate devices, i.e., the modem 310 may also be located in an external device to the host device in which the controller 350 is located, such as an external set-top box or the like.

The controller 350 controls the operation of the display device and responds to the user's operations through various software control programs stored on the memory. The controller 350 controls the overall operation of the display apparatus 300. For example: in response to receiving a user command to select a UI object to be displayed on the display 360, the controller 350 may perform an operation related to the object selected by the user command.

In some embodiments the controller includes at least one of a central processing unit (Central Processing Unit, CPU), video processor, audio processor, graphics processor (Graphics Processing Unit, GPU), RAM Random Access Memory, RAM), ROM (Read-Only Memory, ROM), first to nth interfaces for input/output, a communication Bus (Bus), and the like.

The user may input a user command through a Graphical User Interface (GUI) displayed on the display 360, and the user input interface receives the user input command through the Graphical User Interface (GUI). Alternatively, the user may input the user command by inputting a specific sound or gesture, and the user input interface recognizes the sound or gesture through the sensor to receive the user input command.

A "user interface" is a media interface for interaction and exchange of information between an application or operating system and a user, which enables conversion between an internal form of information and a user-acceptable form. A commonly used presentation form of the user interface is a graphical user interface (Graphic User Interface, GUI), which refers to a user interface related to computer operations that is displayed in a graphical manner. It may be an interface element such as an icon, a window, a control, etc. displayed in a display screen of the display device, where the control may include a visual interface element such as an icon, a button, a menu, a tab, a text box, a dialog box, a status bar, a navigation bar, a Widget, etc.

In some embodiments, the display 360 in the display device 300 is configured to display a user interface, an image, text, video, etc., and the controller 350 in the display device 300 is configured to provide the user interface, the image, the text, the video, etc. to the display 360, the controller 350 or the control apparatus 200 may control the fixed component, and thereby enable rotation of the display device 200 by the fixed component, to transition the display device 300 between the landscape state and the portrait state.

In some embodiments, the display device 300 may enable the display device 300 to support touch interactive functionality through the touch component 380. In general, touch assembly 380 may together form a touch screen with display 360. On the touch screen, the user can input different control instructions through touch operation. For example, a user may input touch instructions such as clicking, sliding, long pressing, double clicking, etc., and different touch instructions may represent different control functions.

To implement the different touch actions described above, the touch assembly 380 may generate different electrical signals when the user inputs the different touch actions, and transmit the generated electrical signals to the controller 350. The controller 350 may perform feature extraction on the received electrical signal to determine a control function to be performed by the user based on the extracted features.

For example, when a user enters a click touch action at any program icon location in the application program interface, the touch component 380 will sense the touch action to generate an electrical signal. After receiving the electrical signal, the controller 350 may first determine the duration of the level corresponding to the touch action in the electrical signal, and recognize that the user inputs the click command when the duration is less than the preset time threshold. The controller 350 then extracts the location features generated by the electrical signals to determine the touch location. When the touch position is within the application icon display range, it is determined that a click touch instruction is input by the user at the application icon position. Accordingly, the click touch instruction is used to perform a function of running a corresponding application in the current scenario, and thus the controller 350 may start running the corresponding application.

For another example, when the user inputs a sliding motion in the media presentation page, the touch assembly 380 also sends the sensed electrical signal to the controller 350. The controller 350 first determines the duration of the touch action corresponding signal in the electrical signal. When the duration time is determined to be longer than the preset time threshold value, the position change condition generated by the signals is judged, and obviously, the generation position of the signals changes for the interactive touch action, so that the user is determined to input a sliding touch instruction. The controller 350 then determines the sliding direction of the sliding touch command according to the change condition of the signal generating position, and controls the page turning of the display screen in the media display page to display more media options. Further, the controller 350 may further extract characteristics such as a sliding speed and a sliding distance of the sliding touch instruction, and perform a picture control of turning pages according to the extracted characteristics, so as to achieve a following effect.

Similarly, for the touch instructions such as double-click and long-press, the controller 350 may extract different features, determine the type of the touch instruction through feature judgment, and execute corresponding control functions according to a preset interaction rule. In some embodiments, the touch assembly 380 also supports multi-touch so that a user can enter touch actions on the touch screen via multiple fingers, e.g., multi-finger clicks, multi-finger long presses, multi-finger swipes, etc.

The touch control action can be matched with a specific application program to realize a specific function. For example, after the user opens the "whiteboard" application, the display 360 may present a drawing area, the user may draw a specific touch action track in the drawing area through the sliding touch command, and the controller 350 determines a touch action pattern through the touch action detected by the touch component 380, and controls the display 360 to display in real time, so as to satisfy the demonstration effect. It will be appreciated that in general, implementation of display device functions requires software in addition to the hardware support described above.

Fig. 6 is a software structure block diagram of a display device provided in an embodiment of the present application.

In some embodiments, as shown in fig. 6, the system of the display device is divided into four layers, namely, an application (Applications) layer (abbreviated as "application layer"), an application framework (Application Framework) layer (abbreviated as "framework layer"), a An Zhuoyun-line (Android run time) and a system library layer (abbreviated as "system runtime layer"), and a kernel layer from top to bottom.

In some embodiments, at least one application program is running in the application program layer, and these application programs may be a Window (Window) program of an operating system, a system setting program, a clock program, or the like; or may be an application developed by a third party developer. In particular implementations, the application packages in the application layer are not limited to the above examples.

The framework layer provides an application programming interface (application programming interface, API) and programming framework for the application. The application framework layer includes a number of predefined functions. The application framework layer corresponds to a processing center that decides to let the applications in the application layer act. Through the API interface, the application program can access the resources in the system and acquire the services of the system in the execution. In some examples, the dialog system included with the display device may be located in a framework layer of the system of the display device.

As shown in fig. 6, the application framework layer in the embodiment of the present application includes a manager (manager), a Content Provider (Content Provider), and the like, where the manager includes at least one of the following modules: an Activity Manager (Activity Manager) is used to interact with all activities that are running in the system; a Location Manager (Location Manager) is used to provide system services or applications with access to system Location services; a Package Manager (Package Manager) for retrieving various information about an application Package currently installed on the device; a notification manager (Notification Manager) for controlling the display and clearing of notification messages; a Window Manager (Window Manager) is used to manage bracketing icons, windows, toolbars, wallpaper, and desktop components on the user interface.

In some embodiments, the activity manager is used to manage the lifecycle of the individual applications as well as the usual navigation rollback functions, such as controlling the exit, opening, fallback, etc. of the applications. The window manager is used for managing all window programs, such as obtaining the size of the display screen, judging whether a status bar exists or not, locking the screen, intercepting the screen, controlling the change of the display window (for example, reducing the display window to display, dithering display, distorting display, etc.), etc.

In the embodiment of the application program framework layer, the application program framework layer can further comprise a low-power consumption standby module. The low-power consumption standby module can be used for executing the low-power consumption standby method provided by the embodiment of the application. I.e. a low power consumption standby module, which can be used to adjust the power resource of the SOC of the display device itself to a power resource capable of supporting only far-field voice wake-up function when the display device is in a wake-up standby state.

In some embodiments, the system runtime layer provides support for the upper layer, the framework layer, and when the framework layer is in use, the android operating system runs the C/C++ libraries contained in the system runtime layer to implement the functions to be implemented by the framework layer.

In some embodiments, the kernel layer is a layer between hardware and software. As shown in fig. 6, the kernel layer contains at least one of the following drivers: audio drive, display drive, bluetooth drive, camera drive, WIFI drive, USB drive, HDMI drive, sensor drive (e.g., fingerprint sensor, temperature sensor, pressure sensor, etc.), and power supply drive, etc.

The methods in the following embodiments may be implemented in a display device having the above-described hardware structure or software structure.

The following describes the low power consumption standby method according to the embodiment of the present application in detail with reference to fig. 7. As shown in fig. 7, taking a display device as an example of a television set for illustration, the low power consumption standby method provided in the embodiment of the present application may include the following S701-S720.

S701, powering on the television.

The television is powered on and may also be referred to as a cold start (i.e., cold_reboot) of the television. The television is powered on, namely, a user inserts the power supply of the television, so that the television can be started in an alternating current mode.

The cold start of the television refers to restarting the television after the television is completely turned off. In the cold start process, the television set performs comprehensive self-checking and initializing operations, including loading an operating system, initializing hardware equipment and the like. Unlike power up, a cold start clears all data and buffers in the television without retaining any information.

It should be noted that, after the television is turned on in an alternating manner, the television can also determine whether the television is a factory condition. Under the condition that the television is determined to be a factory, the television can be directly started, namely, the television can be directly started. In the case where the television is determined to be non-factory, the television may determine whether to power up and power on.

The factory condition of a television refers to the production process and manufacturing environment of the television, including production process, production line, production equipment, working environment, etc. The non-factory condition of a television refers to the condition of the television in terms of use, maintenance, repair, etc. after leaving the factory.

S702, determining whether power-on and power-on are performed.

After the television is powered on, the television can firstly determine whether the television is powered on or not, namely, the television can determine whether the television is automatically powered on or not after the television is powered on, so that whether the television is in a power-on state or not.

In some examples, the television may be powered on automatically after the television is powered on, i.e., automatically enter a powered on state after the television is powered on. After the television is powered on, the television can not be automatically started, namely the television can not automatically enter a starting state after the television is powered on, the television can continuously determine whether the state of the standby wake-up switch of the television is an on state, namely the television can continuously determine whether the television needs to enter the low-power consumption standby wake-up state or the ultralow-power consumption standby state.

In other examples, after the television is powered on, the user may operate the television to perform automatic power-on, that is, after the television receives a power-on operation of the user (such as a power-on operation performed by the user using a remote controller corresponding to the television), the television may enter a power-on state. After the television is powered on, when the television does not receive the starting operation of a user, the television cannot automatically enter the starting state after the television is powered on, the television can continuously determine whether the state of the standby wake-up switch of the television is an on state, namely the television can continuously determine whether the television needs to enter the low-power consumption standby wake-up state or the ultralow-power consumption standby state.

The starting state is that the SOC of the television is in a full-speed running state, that is, the frequency of a CPU in the SOC of the television is in the highest frequency, all cores of the CPU are in a running state, and the memory of the television is in a full-use state. When the television is in a starting state, the display screen of the television is in a non-extinguishing state (namely, the display screen is in a display state and can display corresponding contents), and the system of the television is in an operating state. When the television is in a starting state, because the SOC of the television is in a full-speed running state, the power consumption of the television is full-speed power consumption, and the power consumption of the television is highest at the moment. In the power-on state in this embodiment of the present application, the power consumption of the television may also be referred to as second power consumption.

The ultra-low power consumption standby state, i.e. the SOC of the television is in a completely frozen state (i.e. a freeze state), i.e. the CPU and the memory in the SOC of the television may be in a sleep or low power consumption state. When the television is in the ultra-low power consumption standby state, the display screen of the television is in an off state, and the system of the television is in a non-running state. When the television is in the ultra-low power consumption standby state, the power consumption of the television is lowest because the system of the television is in a non-running state and the display screen is in an off state. In the embodiment of the present application, in the standby state with ultra-low power consumption, the power consumption of the television may also be referred to as third power consumption.

For example, taking a CPU of the SOC of the television set as an example, the CPU includes 4 cores, each of which corresponds to one memory, the operation configuration of the SOC of the television set in the on state (i.e., the computing power resource) and the operation configuration of the SOC of the television set in the ultra-low power consumption standby state (i.e., the computing power resource) are schematically illustrated.

The corresponding memory of each core may be double data rate synchronous dynamic random access memory (DDR). DDR is used as a transit warehouse of the SOC chip for reading and writing data. That is, when the system in the SOC of the television is running, the system is running through the memory corresponding to each core.

As shown in connection with fig. 8, the CPU of the SOC of the television set includes 4 cores, i.e., core 1, core 2, core 3, and core 4. The maximum value of the frequencies corresponding to core 1, core 2, core 3, and core 4 may be 1.5 gigahertz (GHz). The memory corresponding to the core 1 may be the memory 1 (i.e., DDR 1), the memory corresponding to the core 2 may be the memory 2 (i.e., DDR 2), the memory corresponding to the core 3 may be the memory 3 (i.e., DDR 3), and the memory corresponding to the core 4 may be the memory 4 (i.e., DDR 4).

It should be noted that, as shown in fig. 8, an arbiter (i.e. arbiter) may be further included between the core and the memory of the CPU. An arbiter is a mechanism for coordinating and managing interactions and operations between the different hardware components to ensure smooth operation and stable performance of the television system. The arbiter is typically integrated in the chip or system of the television and is responsible for handling and coordinating requests and conflicts between the different hardware to ensure the overall performance and stability of the television.

When the television is in a starting state, as the SOC of the television is in a full-speed running state, the frequency of the CPU in the SOC of the television is at the highest frequency, all the cores of the CPU are in a running state, and the memory of the television is in a full-use state. When the television is in a starting state, the kernel 1, the kernel 2, the kernel 3 and the kernel 4 of the CPU of the television are all in an operation state, and the frequencies are all the maximum, namely all 1.5GHz. When the television is in a starting state, the memory 1, the memory 2, the memory 3 and the memory 4 of the CPU of the television are all in a use state, so that the system of the television can be in an operation state. Because the kernel 1, the kernel 2, the kernel 3 and the kernel 4 of the CPU of the television are all in an operation state, and the memory 1, the memory 2, the memory 3 and the memory 4 of the CPU are all in a use state, the power consumption of the television is full-speed power consumption, and at the moment, the power consumption of the television is the highest.

When the television is in the ultra-low power consumption standby state, the CPU and the memory in the SOC of the television can be in a dormant or low power consumption state because the SOC of the television is in a completely frozen state (i.e. a freeze state). That is, when the television is in the ultra-low power consumption standby state, the core 1, the core 2, the core 3 and the core 4 of the CPU of the television are all in the non-use state (the non-use state in the embodiment of the present application may also be referred to as the sleep state), and the memory 1, the memory 2, the memory 3 and the memory 4 of the CPU are all in the non-use state, so that the power consumption of the television is the lowest.

In the case where the television determines that the power-on is not turned on, the television may continue to determine whether the state of the standby wake-up switch of the television is an on state, i.e., may continue to execute S703 described below. In the case that the television determines that power-on is turned on, the television may perform a power-on operation, i.e., S714 described below may be continuously performed.

S703, determining whether the state of the standby wakeup switch is on.

After the television is powered on, and when the television determines that the power on is not turned on, the television can determine whether the state of the standby wake-up switch of the television is in an on state.

The standby wake-up switch can be used for realizing the far-field voice wake-up function of the television. Namely, when the switch state of the standby wake-up switch is an on state, the television can realize the far-field voice wake-up function. When the switch state of the standby wake-up switch is in the off state, the television cannot realize the far-field voice wake-up function.

In the case where the television determines that the state of the standby wakeup switch is the on state, the television may perform a boot loading operation, so that the television may be adjusted to a low power consumption standby wakeup state, that is, S704 described below may be continuously performed. In the case that the television determines that the state of the standby wake-up switch is the off state, the television may enter the ultra-low power standby state, i.e., the following S720 may be continuously executed.

S704, performing a boot loading operation.

When the television determines that the state of the standby wake-up switch of the television is an on state, the television can perform a boot loading operation (namely a uboot operation), so that the television can configure the power resource of the SOC of the television as the power resource corresponding to the low-power standby wake-up state, and the television can enter the low-power standby wake-up state.

A bootload operation (i.e., uboot operation) can support a variety of processor architectures and embedded systems, and can independently boot an operating system and load a kernel. In a television, the uboot operation is responsible for starting and loading an operating system, and controlling and managing the operation of the entire system. Through uboot operation, the U-Boot of the television can be upgraded or the Boot program can be repaired, so that the new operating system version or the problem of repairing and guiding can be better supported.

That is, after the television performs the uboot operation, the television may configure the power resources of the SOC of the television to the power resources corresponding to the low power standby awake state, so that the television may enter the low power standby awake state.

S705, storing the configuration file corresponding to the low power consumption standby awakening state in the CPU and memory configuration file.

Before the television performs a boot loading operation (i.e., uboot operation), so that the television configures the power resources of the SOC of the television as the power resources corresponding to the low-power standby awake state, the television may store the configuration file corresponding to the low-power standby awake state in the CPU and memory configuration file.

The CPU and memory configuration files may include configuration files corresponding to the low-power consumption standby awake state (i.e., computing power resources corresponding to the low-power consumption standby awake state), that is, the CPU and memory configuration files may include a core that needs to be operated by the CPU corresponding to the low-power consumption standby awake state, a frequency of operation of the core, a memory that needs to be used, and a size of the memory.

In the low-power consumption standby wake-up state, a core to be operated by a CPU of the display device may also be referred to as a first core, a frequency of the first core may also be referred to as a first frequency, a memory corresponding to the first core may also be referred to as a first memory, and a memory capacity corresponding to the first memory may also be referred to as a first memory capacity. The first core is any core of the at least one core, the first frequency is smaller than the second frequency, the second frequency is the maximum value of the frequency of the first core (i.e. the frequency of the first core in the on state), the first memory capacity is smaller than the second memory capacity, and the second memory capacity is the maximum memory capacity of the first memory (i.e. the memory capacity of the first memory in the on state).

It should be noted that, when the state of the display device is the power-on state, the second core of the CPU is in the power-on state, the frequency of the second core is the second frequency, and the memory capacity of the memory corresponding to the second core is the second memory capacity. The second kernel is all the kernels included in the CPU.

For example, the CPU of the SOC of the television set further includes 4 cores, and each core corresponds to one memory, and the operation configuration (i.e., the computational power resource) of the SOC of the television set in the power consumption standby awake state is schematically described. The memory corresponding to each core may be DDR.

The CPU of the SOC of the television set includes 4 cores, i.e., core 1, core 2, core 3, and core 4. The maximum value of the frequencies corresponding to the core 1, the core 2, the core 3 and the core 4 can be 1.5GHz. The memory corresponding to the core 1 may be the memory 1 (i.e., DDR 1), the memory corresponding to the core 2 may be the memory 2 (i.e., DDR 2), the memory corresponding to the core 3 may be the memory 3 (i.e., DDR 3), and the memory corresponding to the core 4 may be the memory 4 (i.e., DDR 4).

As shown in fig. 9, when the television is in the power consumption standby wake-up state, only one core of the 4 cores included in the CPU of the SOC of the television is in the running state, that is, the core 1 may be in the running state, and other cores (that is, the core 2, the core 3 and the core 4) included in the CPU of the television are in the non-running state, for example, the frequency of the other cores is zero, in this embodiment, the core 2, the core 3 and the core 4 may also be referred to as a third core, that is, the third core is a core other than the first core in the second core, and the third memory is a memory corresponding to the third core. And the frequency of the core 1 is a frequency capable of satisfying the VAD function, and is not the maximum frequency, for example, when the television is in the power consumption standby awake state, the frequency of the core 1 may be 400 megaHertz (MHz). In addition, when the television is in the power consumption standby wake-up state, the memory in the SOC of the television is configured to be a memory capable of satisfying the VAD function, that is, the memory 1 of the CPU of the television may be in a use state, the size of the memory 1 may be 20 Megabits (MB), and the memories 2, 3 and 4 are all in a non-use state.

When the television is in the power consumption standby awakening state, only one core of the CPU in the SOC of the television is in the running state, and only one memory of the CPU is in the use state. Therefore, when the television is in the power consumption standby awakening state, the power consumption of the television is higher than that of the television in the ultralow power consumption standby state, but is smaller than that of the television in the starting state and smaller than that of the television in the sound box mode. For example, when a television is in a low power standby awake state, the power consumption may be typically 3W. In this embodiment of the present application, in the low power consumption standby awake state, the power consumption of the television may also be referred to as the first power consumption.

In some examples, when the CPU of the SOC of the television includes only one core, the CPU and the memory configuration file may include a configuration file corresponding to the low power consumption standby awake state, that is, the CPU and the memory configuration file may include the frequency of operation of the CPU corresponding to the low power consumption standby awake state and the size of the memory to be used.

It should be noted that, the configuration files corresponding to the low-power consumption standby wake-up state included in the CPU and the memory configuration files, that is, the kernel that needs to be operated by the CPU corresponding to the low-power consumption standby wake-up state included in the CPU and the memory configuration files, the operating frequency of the kernel, the memory that needs to be used, and the size of the memory, may be obtained through testing. The configuration files corresponding to the low-power standby awakening state can be set to different configurations, so that the optimal configuration file is determined under the different configuration files.

The method comprises the steps that a kernel required to be operated by a CPU, the operating frequency of the kernel, a memory required to be used and the size of the memory are set to be different kernels, different frequencies, different memories and memories with different sizes, and standby wakeup is carried out under different environments (such as a quiet environment, a double-point noise environment, different wakeup distances, different wakeup angles, different wakeup decibels, different wakeup times and the like), so that the standby wakeup rate or the standby false wakeup rate of a television is determined under different configuration files. And determining the configuration file with the standby wake-up rate larger than the preset threshold value or the configuration file with the standby false wake-up rate smaller than the preset threshold value as the optimal configuration file, namely the configuration file corresponding to the low-power consumption standby wake-up state.

For example, as shown in table 1, when the television is in the power consumption standby wake-up state, the CPU of the television is only in the running state, the frequency of the core 1 is 400MHz, the memory 1 of the CPU is in the use state, the size of the memory 1 is 20MB, and when the memory 2, the memory 3 and the memory 4 are all in the non-use state, the standby wake-up rate or the standby false wake-up rate of the television can reach the use requirement under different environments.

TABLE 1

The step S705 may be performed before step S706, before step S701, before step S702, before step S703, or before step S704. In the embodiment of the present application, the configuration file corresponding to the low-power standby wake-up state may be stored in the CPU and memory configuration file by the television before S706.

In some examples, the CPU and the memory configuration file may store a configuration file corresponding to the power-on state. The configuration file corresponding to the power-on state may include a core that the CPU needs to run (i.e., all cores of the CPU), a frequency that the CPU needs to run (i.e., a maximum value of the frequency of the core), a memory that needs to be used (i.e., all memories of the CPU), and a size of the memory that needs to be used (i.e., a maximum value of the memory).

In other examples, the CPU and the memory configuration file may store a configuration file corresponding to the standby state with ultra-low power consumption.

The computing power resources corresponding to the ultra-low power consumption standby may include a kernel (i.e., no kernel is required to be run) that needs to be run by a CPU corresponding to the ultra-low power consumption standby, a frequency (e.g., a minimum value of the frequency) that needs to be run by the kernel to be run, a memory that needs to be used (i.e., no memory is required to be in a use state), and a size of the memory that needs to be used (e.g., a minimum value of the memory).

S706, starting one kernel of the CPU, initializing standby wakeup, and not starting other kernels of the CPU.

After the television performs the boot loading operation (i.e., uboot operation), the television may obtain a configuration file corresponding to the low-power consumption standby awake state (i.e., a configuration file of the computing power resource corresponding to the low-power consumption standby awake state) from the CPU and the memory configuration file. After the configuration file corresponding to the low-power consumption standby awakening state is obtained, the television can configure the computing power resource of the SOC of the television according to the configuration file corresponding to the low-power consumption standby awakening state.

When the configuration file corresponding to the low-power consumption standby wakeup state includes a kernel that needs to be operated by the CPU, a frequency of operation of the kernel, a memory that needs to be used, and a size of the memory, the configuration of the computing power resource of the SOC of the television according to the configuration file corresponding to the low-power consumption standby wakeup state may include: one core of the CPU is started, standby wakeup is initialized, and other cores of the CPU are not started.

That is, the television may start the core of the CPU according to the core to be operated by the CPU included in the configuration file corresponding to the low power standby awake state, and the other cores of the CPU are not started, that is, the other cores of the CPU are in the sleep mode. Other cores of the CPU are in sleep mode, i.e., the other cores of the CPU will stop executing instructions, but other peripherals and clocks will continue to run to quickly resume normal operation when needed. The sleep mode can reduce the power consumption of the CPU, prolong the service life of the battery and save energy when in idle.

After the kernel of the CPU is started, the television may perform initialization standby wakeup according to the frequency of the kernel operation, the memory to be used, and the size of the memory included in the configuration file corresponding to the low power consumption standby wakeup state, that is, the television may adjust the frequency of the kernel started in the CPU to the frequency of the kernel operation included in the configuration file corresponding to the low power consumption standby wakeup state, and adjust the memory and the size of the memory corresponding to the kernel started in the CPU to the memory to be used and the size of the memory included in the configuration file corresponding to the low power consumption standby wakeup state.

S707, entering a low-power consumption standby awakening state.

After one kernel of the CPU is started and standby wakeup is initialized by the television, and other kernels of the CPU are not started, namely, the power resources of the SOC of the television are configured to be the power resources corresponding to the low-power standby wakeup state, the television can enter the low-power standby wakeup state.

That is, when the television enters the low power consumption standby wake-up state, the television can adjust the television from the low power consumption standby wake-up state to the power-on state according to the voice wake-up instruction of the user. I.e. the television is able to support far-field voice wake-up functions.

S708, voice input of the user is monitored through the VAD function.

After the television enters a low power standby awake state, the television may monitor the user's voice input by waking up the voice activation detection VAD function.

That is, after the television enters the low power consumption standby awake state, if the user needs to adjust the state of the television from the low power consumption standby awake state to the on state, the user can perform voice input. For example, a user may input a voice such as "power on" to a television.

S709, performing wake-up word recognition on the voice input.

After the television monitors the voice input of the user through the VAD function, the television can recognize wake-up words for the voice input of the user.

Wake-up word recognition, i.e. a specific word or phrase used in the voice interaction system of a television, is used to wake up the system and activate the voice recognition function. Therefore, the television can actively listen to the voice of the user, and more convenient and intelligent interaction experience is provided for the user. I.e. the television set may recognize the user's voice input to determine if a wake up notification is included in the user's voice input.

S710, determining whether the voice input comprises a wake-up notification.

After the television performs wake word recognition on the voice input, the television pair may determine whether a wake notification is included in the voice input.

Wake-up notification, i.e. a preset word in the user's speech input. The preset word can be used for indicating the television to be adjusted from the low-power standby awakening state to the starting state. For example, the wake-up notification may include words such as power on, please power on, etc.

Under the condition that the television determines that the voice input comprises the wake-up notice, the television can determine whether the state of the quick switch of the television is an on state, so that the television can quickly enter the on state when the state of the quick switch is the on state. That is, in the case where the television determines that the wake-up notification is included in the voice input, S716 described below may be continued to be performed.

Under the condition that the television determines that the voice input does not comprise the wake-up notice, the television can continuously enter the low-power standby wake-up state, so that the television can continuously monitor the voice input of the user through the VAD. That is, in the case where the television determines that the wake-up notice is not included in the voice input, the following S711 may be continuously performed.

S711, entering a low-power consumption standby wake-up state.

In the case where the television determines that the wake-up notification is not included in the voice input, the television may continue to enter a low power standby wake-up state. The television may then continue to monitor the user's voice input through the VAD. That is, in the case where the television determines that the wake-up notification is not included in the voice input, the television continues to enter the low power standby wake-up state, and then the television may continue with S708 described above.

S712, determining whether the state of the quick switch is an open state.

In the case where the television determines that the wake-up notification is included in the voice input, the television may determine whether the state of the fast switch is an on state.

The fast switch is a Suspend To RAM (STR) switch. When the state of the fast switch is in an on state, the television can store all system behavior data before the television is in standby in the storage memory, namely, when the television is in standby in an STR state, the power supply only supplies power to the memory and the chip set, and other components are in an off state, so that the power consumption can be greatly saved. When the television is started again, the television can restore the data stored in the memory to the state before starting up usually only by about 2 seconds. That is, the television can be turned on quickly when the state of the quick-turn on switch is an on state.

In the case that the television determines that the state of the fast switch is the on state, the television may perform the fast switch process (i.e., the fast switch mode), that is, the following S716 may be continuously performed. In the case where the television determines that the state of the fast switch is the off state, the television may perform a normal power-on process, i.e., may continue to execute S713 described below.

S713, starting a normal start-up flow.

Under the condition that the television determines that the state of the fast switch is the off state, the television can start a normal starting process, so that the television can be adjusted from the low-power consumption standby awakening state to the starting state.

S714, performing a boot loading operation.

After the television starts the normal starting-up flow, the television can perform a boot loading operation. Therefore, the television can adjust the power computing resources of the SOC of the television from the power computing resources corresponding to the low-power consumption standby awakening state to the power computing resources corresponding to the starting state, and the television can be adjusted from the low-power consumption standby awakening state to the starting state.

S715, initializing all cores of the CPU at full speed, and normally starting all memories.

After the television performs the boot loading operation, the television can adjust the computing power resource of the SOC of the television from the computing power resource corresponding to the low-power standby awake state to the computing power resource corresponding to the power-on state (i.e., the normal power-on mode).

The computing power resources corresponding to the starting state can comprise a kernel which needs to be operated by a CPU corresponding to the starting state, the frequency of the kernel which needs to be operated, a memory which needs to be used and the size of the memory which needs to be used.

Since the system in the SOC of the television needs to run at full speed in the power-on state, the cores that the CPU needs to run in the power-on state may be all cores of the CPU, the frequency at which the cores that the CPU needs to run in the power-on state runs may be the maximum value of the frequency of the cores, the memory that the CPU needs to use in the power-on state may be the memory corresponding to all cores of the CPU, and the size of the memory that needs to use in the power-on state may be the maximum value of the size of the memory that needs to use.

That is, after the tv performs the boot loading operation, the tv may adjust all cores of the CPU to a start state according to the CPU that the configuration file corresponding to the start state includes (i.e., all cores of the CPU) needs to operate the cores, adjust the frequency of the CPU that the configuration file corresponding to the start state includes to a maximum value of the frequency of the cores, adjust the memory that the CPU needs to use to a use state according to the memory that the start state needs to use and the size of the memory that the CPU needs to use, and adjust the size of the memory that the CPU needs to use to a maximum value. After the television performs the boot loading operation, the television can initialize all cores of the CPU at full speed according to the configuration file corresponding to the starting state, and all memories are started normally.

S716, loading the system and starting the display interface.

After the television initializes all cores of the CPU at full speed and all memories are started normally, the television can load the system and start the display interface, namely, the television is adjusted from a low-power consumption standby awakening state to a starting state. After the television has loaded the system and started the display interface, the user can perform various operations, such as playing television programs, browsing the internet, running applications, etc.

S717, entering into a normal use state.

After the television loads the system and starts the display interface, the television enters a normal use state, namely the television enters a starting state. That is, after the television enters a normal use state, the user can perform various operations on the television, such as playing a television program, browsing the internet, running an application program, and the like.

S718, receiving a standby instruction of a user.

After the television enters a normal use state, namely the television enters a starting state, the television can receive a standby instruction of a user. The standby instruction may be used to instruct the television to adjust from a power-on state to a standby state.

The standby state of the television refers to a state in which the television is in an on state when not in use, but without any substantial work (i.e., without various operations on files and programs). In a standby state, the television may maintain a certain level of power consumption, which is referred to as "standby power consumption". The user can control the television to enter a standby state by setting an automatic shutdown time, power protection and the like.

In some examples, the user may input a standby instruction through a remote control corresponding to the television (e.g., the user inputs a shutdown operation through a remote control corresponding to the television), or input a shutdown instruction through voice. That is, when the television receives a shutdown operation input by a user through a remote controller corresponding to the television or a shutdown instruction input by the user through voice, the television receives a standby instruction of the user.

S719, it is determined whether the state of the standby wakeup switch is an on state.

After the television receives the standby instruction of the user, the television may continue to determine whether the state of the standby wake-up switch of the television is an on state in response.

After the television is adjusted to be in the on state, when the user does not need far-field voice wake-up function, namely the television does not need to enter low-power standby wake-up, the user can adjust the state of the standby wake-up switch of the television to be in the off state. Therefore, after the television receives the standby instruction of the user, the television can determine whether the state of the standby wakeup switch of the television is an on state.

Under the condition that the television determines that the state of the standby wakeup switch of the television is an on state, the television can perform guide loading operation, so that the television is adjusted from the on state to the low-power consumption standby wakeup state, namely, the power resource of the SOC of the television is adjusted from the power resource corresponding to the on state to the power resource corresponding to the low-power consumption standby wakeup state. That is, in a case where the television determines that the state of the standby wakeup switch of the television is the on state, the above S704 may be continuously performed.

When the television determines that the state of the standby wake-up switch of the television is the off state, the television can be adjusted to be in the ultralow power consumption standby state in the on state, namely, the computing power resource of the SOC of the television is adjusted from the computing power resource corresponding to the on state to the computing power resource corresponding to the ultralow power consumption standby state. That is, in a case where the television determines that the state of the standby wakeup switch of the television is the off state, the following S720 may be continuously performed.

S720, entering an ultralow power consumption standby state.

And under the condition that the television determines that the state of the standby wakeup switch of the television is the off state, the television can enter the ultralow power consumption standby state. The television can be adjusted to an ultralow power consumption standby state in a starting state, and the computing power resource of the SOC of the television is adjusted from the computing power resource corresponding to the starting state to the computing power resource corresponding to the ultralow power consumption standby state.

The computing power resources corresponding to the ultra-low power consumption standby can comprise cores which need to be operated by the CPU corresponding to the ultra-low power consumption standby, the frequency of the cores which need to be operated, the memory which needs to be used and the size of the memory which needs to be used.

Because the system in the SOC of the television does not need to operate in the ultra-low power consumption standby state, the CPU does not need to operate the kernel in the ultra-low power consumption standby state, the frequency of the kernel which needs to operate in the ultra-low power consumption standby state can be the minimum value or zero of the frequency of the kernel, the memory which needs to be used by the CPU in the ultra-low power consumption standby state can be the memory which does not need to be used, and the size of the memory which needs to be used in the ultra-low power consumption standby state can be the minimum value or zero of the size of the memory which needs to be used.

That is, when the television determines that the state of the standby wake-up switch of the television is the off state, the television may adjust all cores of the CPU to a sleep mode according to the CPU need to run the cores (without running the cores) included in the configuration file corresponding to the ultralow power consumption standby state, adjust the frequency of the cores to a minimum value or adjust the frequency of the cores to zero according to the frequency of the CPU need to run the cores included in the configuration file corresponding to the on state, adjust the memories corresponding to all cores of the CPU to a non-use state (i.e., adjust the memories corresponding to all cores of the CPU to the sleep mode) according to the memory size of the memory that needs to be used and the memory size of the memory that needs to be used.

According to the scheme, when the standby wake-up switch of the television is in the on state and the shutdown operation (namely the standby instruction input by the user) of the user is received, the television can be adjusted to be in the low-power standby wake-up state, and in the wake-up standby state, the computing power resource of the SOC of the television is adjusted to be the computing power resource capable of supporting the far-field voice wake-up function only, so that the far-field voice wake-up function can be supported under the standby state of the display equipment.

When the television is in a low-power consumption standby awakening state, the computing power resource of the SOC of the television is adjusted, and no additional DSP or MCU is needed, so that the cost of the television can be reduced by the scheme of the application. In addition, according to the scheme, the computing power resource of the SOC of the television is adjusted to be the computing power resource capable of supporting the far-field voice awakening function only, so that when the television is in the low-power-consumption standby awakening state, a system of the television cannot be in an operation state, and power consumption of the display equipment can be reduced in the low-power-consumption standby awakening state.

For easy understanding, the low power standby method provided in the embodiment of the present application is described below with reference to fig. 10. The microphone detection method can be applied to a display device. The display device may include: a display, a communicator, and a controller. The communicator may be configured to receive a standby operation of the user. The controller may be configured to perform the following low power consumption standby method.

As shown in fig. 10, the low power consumption standby method may include the following S1001 to S1004.

S1001, receiving a standby operation of the user.

After the display device enters a normal use state, that is, the display device enters a power-on state, the display device may receive a standby operation of a user. The standby operation may be used to instruct the display device to adjust from an on state to a standby state. The standby state may include a low power consumption standby awake state, a dummy standby state, and an ultra low power consumption standby state.

In the starting-up state, the system of the display device is in an operating state, namely the frequency of a CPU in the SOC of the display device is at the highest frequency, all the cores of the CPU are in the operating state, all the memories of the display device are in a full-use state, the display of the display device is in a display state, and a user can watch corresponding contents through the display of the display device. In the power-on state, the power consumption of the display device is the second power consumption.

In the low-power consumption standby wake-up state, the system of the display device is in a non-running state, that is, only one core (i.e., a first core) in the SOC of the display device is in a running state (i.e., in the embodiment of the present application, the frequency of the first core is a first frequency, the first frequency is smaller than a second frequency (the second frequency is the highest frequency of the core), other cores of the CPU are all in a sleep state, and a first memory corresponding to the first core is in a use state, a memory capacity corresponding to the first memory is a first memory capacity, the first memory capacity is smaller than a second memory capacity (the second memory capacity is the maximum memory capacity of the first memory), other memories except the first memory are in a sleep state, and the display device is in a power-off state, so that the display device can receive voice input by a user, and can be adjusted from the low-power consumption standby wake-up state to the power consumption wake-up state, that is, the display device supports a far-field voice function. In the low-power consumption standby awake state, the power consumption of the display device is the second power consumption. In the ultra-low power consumption standby state, the system of the display device is in a non-running state, the display of the display device is in a blanking state, the display device cannot receive voice input by a user, namely the display device does not support far-field voice awakening function. In the ultra-low power consumption standby state, a user can control the display device to adjust from the low power consumption standby awakening state to the starting state through a remote controller corresponding to the display device. In the low-power consumption standby awake state, the power consumption of the display device is the third power consumption.

In the pseudo standby state, the system of the display device is in an operating state, namely the frequency of a CPU in the SOC of the display device is at the highest frequency, all cores of the CPU are in the operating state, all memories of the display device are in a full use state, and a display of the display device is in an off state. In the ultra-low power consumption standby state, a user can control the display device to adjust from the low power consumption standby awakening state to the starting state through a remote controller corresponding to the display device. In the pseudo standby state, the power consumption of the display device is the fourth power consumption. When the state of the display device is a pseudo standby state, the user may trigger the display device to start up through the external infrared remote control corresponding to the display device.

The first power consumption is smaller than the second power consumption, the first power consumption is larger than the third power consumption, and the first power consumption is smaller than the fourth power consumption.

In some examples, the user may input a standby instruction through a remote controller corresponding to the display device (e.g., the user inputs a shutdown operation through the remote controller corresponding to the display device), or input a shutdown instruction through voice, so as to adjust the display device from the on state to the standby state. That is, when the display device receives the shutdown operation input by the user through the remote controller corresponding to the television, or receives the shutdown instruction input by the user through voice, the display device receives the standby operation of the user.

In this embodiment of the present application, the display device may refer to the embodiment in S718 described above for a specific embodiment in which the display device receives the standby operation of the user. The embodiments of the present application are not described herein.

S1002, in response to a standby operation, determining a state of a standby wakeup switch of the display device.

When the display device receives a standby operation of the user, the display device may determine a state of a standby wakeup switch of the display device in response.

The state of the standby wake-up switch may include an off state and an on state. When the display device receives the standby operation of the user in the off state of the standby wake-up switch, the display device can be adjusted from the on state to the ultra-low power consumption standby state. When the display device receives the standby operation of the user in the state that the standby wake-up switch is in the on state, the display device can be adjusted from the on state to the low-power consumption standby wake-up state.

In this embodiment, the specific implementation of determining the state of the standby wakeup switch of the display device in response to the standby operation may refer to the implementation in S719. The embodiments of the present application are not described herein.

S1003, when the state of the standby awakening switch is an on state, acquiring the computing power resource configuration corresponding to the low-power consumption standby awakening state.

And under the condition that the state of the standby awakening switch is an on state, the display equipment can acquire the computing power resource configuration corresponding to the low standby awakening state. And the computing power resource allocation corresponding to the low standby awakening state is used for indicating the allocation of the computing power resource of the SOC of the display equipment in the standby awakening state.

In some examples, the CPU of the display device includes at least one core, and the computing power resource configuration corresponding to the low power consumption standby awake state may include at least one of a first core, a first frequency of the first core, a first memory corresponding to the first core, and a first memory capacity corresponding to the first memory that the CPU of the display device needs to operate when the state of the display device is the low power consumption standby awake state.

The first core is any one core of at least one core, the first frequency is smaller than the second frequency, the second frequency is the maximum value of the frequency of the first core, the first memory capacity is smaller than the second memory capacity, and the second memory capacity is the maximum memory capacity of the first memory. For example, the second frequency may be 1.5GHz, the first frequency may be 400MHz, and the first memory capacity may be 20MB.

In this embodiment, the CPU of the display device includes a plurality of cores, and the computing power resource configuration corresponding to the low-power consumption standby awake state may include, for example, a first core, a first frequency of the first core, a first memory corresponding to the first core, and a first memory capacity corresponding to the first memory that need to be operated by the CPU of the display device when the state of the display device is the low-power consumption standby awake state.

In some examples, when the state of the display device is a power-on state, a second core of a CPU of the display device is a power-on state, a frequency of the second core is a second frequency, and a memory capacity of a memory corresponding to the second core is a second memory capacity. The second kernel is all the kernels included in the CPU.

Before the display device obtains the computing power resource configuration corresponding to the low-power consumption standby wakeup state, the display device may store the computing power resource configuration corresponding to the low-power consumption standby wakeup state, so that the display device may adjust from the power-on state to the low-power consumption standby wakeup state according to the stored computing power resource configuration corresponding to the low-power consumption standby wakeup state.

In some examples, in the case where the state of the standby wakeup switch is an off state, the display device may control the state of the display device to be adjusted from an on state to an ultra-low power consumption standby state. And when the state of the display equipment is the ultralow power consumption standby state, all cores and all memories of a CPU of the display equipment are in a sleep state.
