[0038] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0039] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0040] The display device provided in this application can have various implementation forms, such as a television, a smart television, a laser projection device, a monitor, an electronic bulletin board, an electronic table, etc. Figure 1 and Figure 2 This is one specific embodiment of the display device of this application.

[0041] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0042] In the Android system, ReportID and HIDraw nodes are typically associated with input devices (such as keyboards, mice, touchscreens, etc.), especially when dealing with Human Interface Device (HID) protocols.

[0043] In this embodiment of the disclosure, Report ID is a field in the HID device report descriptor used to identify different types of reports. HID devices can send various types of data reports (such as input reports, output reports, and feature reports), and each report has a unique ReportID.

[0044] In this embodiment of the disclosure, HIDraw is a subsystem in the Linux kernel that provides a low-level access interface to HID devices. Through the HIDraw interface, applications can directly communicate with HID devices, reading and writing raw data without needing to go through a higher-level input subsystem.

[0045] The GATT (Generic Attribute Profile) service in this disclosure is a core concept in the Bluetooth Low Energy (BLE) protocol, used to define how BLE devices organize and transmit data.

[0046] In this disclosure, ADC, or analog-to-digital converter, generally refers to an electronic component that converts analog signals into digital signals.

[0047] Figure 1 This is a schematic diagram illustrating an operational scenario between a home appliance and a control device according to one or more embodiments of this application, such as... Figure 1 As shown, a user can operate the display device 200 through the terminal device 300 and / or the control device 100. The control device 100 can be a remote control, and communication between the remote control and the display device includes infrared protocol communication, Bluetooth protocol communication, wireless or other wired methods to control the display device 200. The user can input user commands through buttons on the remote control, voice input, control panel input, etc., to control the display device 200. In some embodiments, mobile terminals, tablet computers, computers, laptops, and other smart devices can also be used to control the display device 200.

[0048] In some embodiments, the electronic device provided in this disclosure can be the display device 200 described above, and the control device can be the control device 100 described above. When the display device 200 and the control device 100 establish a pairing relationship, the control device 100 can control the display device 200, and the display device 200 displays a control that can turn the far-field voice acquisition function on or off. Thus, the user can control the far-field voice acquisition function of the control device 100 on the display device 200. Afterwards, while using the display device 200, the user can install a singing application on the display device 200 to sing on the display device 200. When the user wants to sing, they can first enable the far-field voice acquisition function of the control device 100 on the display device 200, and then open the application to sing. At this time, in response to the opening operation of the application for singing, if the control device with an established communication connection has enabled the far-field voice acquisition function, the display device 200 sends a first control message to the control device; the first control message instructs the control device to start acquiring singing voice data at a first sampling rate; when the control device 100 receives the first control message sent by the display device 200, it acquires singing voice data at the first sampling rate; the control device 100 sends the singing voice data to the display device 200. The display device 200 receives the singing voice data sent by the control device 100 and plays the singing voice data.

[0049] As can be seen, since the control device can control the display device and also has far-field voice acquisition capabilities, when a user wants to sing, they can activate the far-field voice acquisition function of the control device on the display device. Simultaneously, when a singing application is opened on the display device, the display device, in response to the opening of the singing application, sends first control information to the control device if the control device, with an established communication connection, has activated its far-field voice acquisition function. Thus, the display device can instruct the control device to acquire singing voice data. Afterward, the display device receives the singing voice data sent by the control device and plays it. In this way, users do not need to purchase additional equipment to sing; instead, they can sing through the control device on the display device. Because the control device and display device are better matched, the number of mismatches between the singing device and the display device can be reduced, thereby lowering the mismatch rate and improving the user experience.

[0050] Figure 2 A hardware configuration block diagram of a display device 200 according to an exemplary embodiment is shown. For example... Figure 2The display device 200 shown includes at least one of the following: a tuner / demodulator 210, a communicator 220, a detector 230, an external device interface 240, a controller 250, a display 260, an audio output interface 270, a memory, a power supply, and a user interface 280. The controller includes a central processing unit, a video processor, an audio processor, a graphics processor, RAM, ROM, and a first to nth interface for input / output. The display 260 may be a touch-enabled display, such as a touch screen display. The detector 230 is used to acquire signals from the external environment or for interaction with the external environment.

[0051] In some examples, the external device interface 240 may include, but is not limited to, one or more of the following interfaces: 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, etc. It may also be a composite input / output interface formed by multiple interfaces mentioned above.

[0052] In some embodiments, the controller 250 controls the operation of the display device and responds to user operations through various software control programs stored in memory. The controller 250 controls the overall operation of the display device 200.

[0053] In some examples, the display device 200 of one or more embodiments is a television set 1, and the operating system of the television set 1 is the Android system, for example... Figure 3 As shown, TV 1 can be logically divided into an application layer (referred to as "application layer") 21, an application framework layer (referred to as "framework layer") 22, an Android runtime and system library layer (referred to as "system runtime library layer") 23, and a kernel layer 29.

[0054] The application layer 21 includes one or more applications. These applications can be system applications or third-party applications. The framework layer 22 provides application programming interfaces (APIs) and programming frameworks for the applications in the application layer 21. The system runtime library layer 23 provides support for the upper layer, namely the framework layer 22. When the framework layer 22 is used, the Android operating system runs the C / C++ libraries contained in the system runtime library layer 23 to implement the functions required by the framework layer 22. The kernel layer 29 acts as software middleware between the hardware layer and the application layer 21, and is used to manage and control hardware and software resources.

[0055] In some examples, the electronic device provided in this application embodiment can be the aforementioned television set 1. When the control device 100 is a remote control, after the television set 1 and the remote control establish a pairing relationship, the remote control can control the television set 1, and the television set 1 displays controllable controls to enable or disable the far-field voice acquisition function. Thus, the user can control the activation or deactivation of the remote control's far-field voice acquisition function on the television set 1. Subsequently, while using the television set 1, the user can install a singing application (such as referred to as the first application) on the television set 1, thereby enabling singing on the television set 1. When the user wants to sing, they can first enable the far-field voice acquisition function of the remote control on the television set 1, and then open the application to sing. At this time, in response to the opening operation of the application for singing, if the remote control with established communication connection has enabled the far-field voice acquisition function, the processing unit 201 of the television set 1 controls the transceiver unit 202 to send first control information to the remote control; when the transceiver unit 302 receives the first control information sent by the television set 1, the processing unit 301 of the remote control collects singing voice data according to the first sampling rate; the processing unit 301 of the remote control controls the transceiver unit 302 to send the singing voice data to the display device 200. When the transceiver unit 202 receives the singing voice data sent by the remote control, the processing unit 201 of the television set 1 plays the singing voice data received by the transceiver unit 202.

[0056] Specifically, when the executing entity of the voice playback method provided in this embodiment is a television set 1, the storage unit 203 of the television set 1 is used to store data such as the program code of the voice playback method provided in this embodiment.

[0057] In the following embodiments, the television set 1 described above is used as the execution subject for the voice playback method provided in the embodiments of this disclosure to illustrate the method of the present application.

[0058] This application provides a voice playback method, applied to a television set 1, such as... Figure 4 As shown, the voice playback method may include S11 and S12.

[0059] S11. In response to the opening operation of the application used for singing, if the control device with an established communication connection has enabled the far-field voice acquisition function, a first control message is sent to the control device; wherein the control device has the functions of controlling electronic devices and far-field voice acquisition, and the first control message is used to instruct the control device to start acquiring singing voice data according to a first sampling rate.

[0060] In some examples, the television 1 can determine whether the remote control has far-field voice acquisition capabilities by using the target identifier reported by the control device (such as a remote control).

[0061] For example, the process by which TV 1 determines whether the remote control supports far-field voice acquisition (such as karaoke function) is as follows:

[0062] The TV set 1 and the remote control agree on a target identifier, such as a Report ID, to determine whether the remote control supports far-field voice acquisition. The Report ID used to identify far-field voice acquisition is different from the Report ID used to identify near-field voice acquisition.

[0063] TV 1 can be read through the HIDraw node. If the Report ID used to identify the far-field voice acquisition function is read, it means that the remote control supports the karaoke function. If the Report ID used to identify the far-field voice acquisition function is not read, it means that the remote control does not support the karaoke function.

[0064] The definitions related to Report ID are as follows:

[0065] The remote control requires three report characteristics for the transmission of control data and voice data. The specific definitions are shown in the table below:

[0066] Table 1

[0067]

[0068] For example, a Report ID of 0x5E indicates that the TV sends control information to the remote control; or a Report ID of 0x5A indicates that the remote control sends control information to the TV; or a Report ID of 0xF7 indicates that the remote control supports karaoke functionality.

[0069] After the TV receives the Report ID used to identify the far-field voice acquisition function, it displays the remote control's controls to turn the far-field voice acquisition function on or off in the menu interface. The process by which TV 1 reads the Report ID is as follows:

[0070] When the remote control and TV 1 pair via Bluetooth, TV 1 reads the ReportID value and Report type supported by the remote control and stores them in the HIDraw node representing the remote control in the application framework layer. The application in TV 1's application layer reads the data from the HIDraw node representing the remote control in the application framework layer to determine if the Report ID 0xF7 exists and if the Report type is input. If the Report ID 0xF7 is present and the Report type is input, it means the current remote control supports far-field voice capture. In this case, controls to enable or disable far-field voice capture can be displayed in the menu interface. Conversely, if the remote control does not support far-field voice capture, the controls to enable or disable far-field voice capture will not be displayed in the menu interface.

[0071] As can be seen, the TV can determine whether the remote control supports far-field voice capture by using the Report ID in the HIDraw field used to represent the remote control. Furthermore, to differentiate between far-field and near-field voice capture functions, the Report ID can be set separately, allowing for flexible differentiation between these functions. For example, when there is a conflict between the use cases of far-field and near-field voice capture functions, their on / off states can be precisely controlled separately.

[0072] In some examples, TV 1 can also determine whether the remote control supports far-field voice capture by creating a GATT service. For example, TV 1 uses a custom GATT service Universally Unique Identifier (UUID) to identify whether the remote control supports far-field voice capture.

[0073] In some examples, the far-field voice acquisition function means that after the remote control receives the first control information, it turns on the microphone and starts to collect environmental voice data according to the first sampling rate, and uses the collected environmental voice data as singing voice data.

[0074] In some examples, the near-field voice acquisition function activates the microphone to collect ambient voice data when the voice button on the remote control is pressed, and uses the collected ambient voice data as near-field voice data.

[0075] S12. Receive the singing voice data sent by the control device and play the singing voice data.

[0076] In some examples, TV 1 and the remote control establish a communication connection via Bluetooth. TV 1 can then receive the singing voice data sent by the remote control via the Bluetooth module, perform decompression and other processing, and finally play the singing voice data and music together from the speakers.

[0077] As described above, the voice playback method provided in this disclosure, since the control device can control the electronic device and has a far-field voice acquisition function, allows the user to sing by activating the far-field voice acquisition function of the control device on the electronic device. Simultaneously, when a singing application is opened on the electronic device, the electronic device responds to the opening operation of the singing application. If the control device, with an established communication connection, has activated its far-field voice acquisition function, it sends first control information to the control device. Thus, the display electronic device can instruct the control device to acquire singing voice data. Afterward, the electronic device receives the singing voice data sent by the control device and plays it. Therefore, users do not need to purchase additional equipment for singing; instead, they can sing through the control device of the electronic device. Because the matching between the control device and the electronic device is better, the number of mismatches between the singing device and the electronic device can be reduced, thereby reducing the mismatch rate between the singing device and the display device and improving the user experience.

[0078] In some feasible examples, combining Figure 4 ,like Figure 5 As shown, the voice playback method provided in this embodiment of the present disclosure further includes: S13 and S14.

[0079] S13. In response to the control device's selection operation of the volume control in the display page corresponding to the application, determine the adjusted input volume value.

[0080] In some examples, to facilitate user adjustment of the voice input level of the remote control, the voice playback method provided in this disclosure embodiment controls the voice input level of the remote control through the TV interface. For example, if the far-field voice acquisition function of the remote control is enabled on the TV interface, the user can use the remote control to select a volume bar control displayed on the TV interface (e.g., the volume bar control's volume value includes any one of 1-10, and the volume value is an integer). The TV 1 then sends the adjusted volume value to the remote control. The remote control adjusts its volume gain value based on the received volume value. For example, if the adjusted volume value is 5, the remote control determines the volume gain value based on the received adjusted volume value. For instance, the remote control determines the gain range corresponding to the adjusted volume value. The remote control uses the theoretical gain value corresponding to this gain range as the volume gain value.

[0081] Alternatively, the remote control can use the adjusted volume value and input it into the volume gain formula to obtain the volume gain value.

[0082] The gain formula includes:

[0083] d = a(ba) - c; where d represents the volume gain value, a represents the adjusted volume value, b represents the total number of volume values ​​of the volume bar control, and c represents the adjustment coefficient, c∈[0,1].

[0084] For example, if the volume value is an integer and the volume bar control's volume value includes any value from 1 to 10, then the total volume value of the volume bar control is 10.

[0085] In some examples, changing the volume gain via a remote control better preserves the quality of the original speech. However, if the volume gain is changed via TV 1, the quality of the singing speech data will deteriorate, resulting in problems such as audio distortion. The reasons are as follows:

[0086] The processing logic and results of adjusting the volume gain via TV 1 are as follows:

[0087] Assume the original singing voice data collected by the remote control is converted into a digital signal 'a' (e.g., 'a' is 16-bit data) by an ADC. After being processed by the remote control's amplifier, the voice signal corresponding to the singing voice data is amplified by x times, generating a signal of a×x. Since the remote control needs to maintain a preset data format, such as 16-bit data format, it is necessary to discard some decimal places (rounding). The transmitted signal becomes a×xc, where c represents the value of the discarded data.

[0088] If only one decimal place needs to be retained, then: |c| < 0.1;

[0089] After the TV receives the data, it amplifies the gain, and the adjusted data is: (a×xc)×y=a×x×yc×y;

[0090] Since the magnification factor y > 1, c × y may be greater than 0.1.

[0091] The processing logic and results for adjusting the volume gain using the remote control are as follows:

[0092] Assume the raw singing voice data acquired by the remote control is converted into a digital signal 'a' (where 'a' is 16-bit data) by an ADC. After processing by the remote control's default amplifier, the voice signal is amplified by a factor of x, resulting in a × x signal. Then, the remote control adjusts the volume, and the required amplification factor is assumed to be 'y' (i.e., the volume gain). Therefore, the final output signal should be a × x × y.

[0093] The processing logic and results of adjusting the volume gain via remote control are as follows:

[0094] Since the remote control itself needs to perform data amplification processing, this volume gain adjustment can be combined with the original amplification factor and amplified simultaneously. The processed signal is then: a×x×y. Because the voice data becomes larger after amplification, 16 bits cannot record all the data, and the transmission still needs to use the 16-bit format. Therefore, some decimal places need to be discarded (rounded) to ensure data transmission. The discarded data becomes: a×x×yb (b is the value of the discarded supplementary data). Assuming that only one decimal place needs to be retained, then: |b|<0.1.

[0095] The results above show that after adjusting the gain via remote control, the final output signal error does not exceed 0.1; however, after adjusting the gain via the TV, the final output signal error may exceed 0.1 or even greater. Therefore, if the input volume adjustment of the singing voice data is achieved through TV 1, problems such as reduced voice quality or distortion are more likely to occur. Therefore, this disclosure uses a remote control to adjust the volume gain of the collected singing voice data, thereby ensuring a better user experience.

[0096] In some examples, the control command data format carrying the adjusted volume value sent by TV 1 to the remote control is shown in Table 2.

[0097] Table 2

[0098]

[0099] In some examples, the remote control collects the singing voice data from the analog signal, converts the analog signal into a digital signal through an ADC, amplifies the signal through an amplifier, and finally sends the amplified singing voice data to the television 1.

[0100] S14. Send a second control message carrying a volume value to the control device; wherein the second control message is used to instruct the control device to adjust the volume gain of the collected singing voice data according to the volume value.

[0101] In some examples, after sending the first control information to the remote control, TV 1 periodically (e.g., every 3 seconds) sends a microphone status data packet command to the remote control: Karaoke_mic_start, with the data format shown in Table 3.

[0102] Table 3

[0103]

[0104] In some examples, TV 1 instructs the remote control to turn off the karaoke function: Karaoke_mic_stop, with the data format shown in Table 4.

[0105] Table 4

[0106]

[0107] In some examples, the remote control outputs the command "karaoke_voice_start" indicating that the far-field voice acquisition function is enabled, with the data format shown in Table 5.

[0108] Table 5

[0109]

[0110] In some examples, the remote control's feedback field voice capture function is disabled via the command: karaoke_voice_stop, with the data format shown in Table 6.

[0111] Table 6

[0112]

[0113] In some feasible examples, combining Figure 4 ,like Figure 6 As shown, the voice playback method provided in this embodiment of the present disclosure further includes: S15 and S16.

[0114] S15. During the playback of singing voice data, if an operation message for enabling the near-field voice function is received, obtain the first priority of the application and the second priority of the near-field voice function.

[0115] S16. If the first priority is greater than the second priority, the near-field voice function is not activated, and the control device is instructed to continue acquiring singing voice data.

[0116] For example, when the first priority is greater than the second priority, the interaction process between TV 1 and the remote control includes:

[0117] 1. TV 1 sends Karaoke_mic_start to remote control, and remote control receives the Karaoke_mic_start command sent by TV 1.

[0118] 2. Use the remote control to start the hardware, turn on the microphone (MIC), and power it on.

[0119] 3. The remote control begins collecting singing voice data. After the remote control powers the microphone, the microphone will begin collecting singing voice data. At this time, the microphone may pick up noise from button presses and sounds of microphone instability. Therefore, after the remote control powers the microphone, a preset delay can be set before starting the collection of singing voice data. For example, the preset delay could be 100ms.

[0120] 4. The remote control sends the Karaoke_voice_start command to TV 1.

[0121] 5. The remote control transmits the collected singing voice data to TV 1. For example, the data packet format of the singing voice data can be 42 bytes in length, with singing voice data in large packets every 10ms, compressed and transmitted.

[0122] 6. During the transmission of singing voice data, the remote control needs to determine whether there are any operations or commands that conflict with the karaoke function. For example, the remote control will detect whether the voice key or other buttons are pressed. If a button is pressed, the karaoke function will not be exited. The remote control will only send the corresponding button (including the voice key) key value to TV 1 and will not activate the near-field voice function. After receiving the button key value sent by the remote control, TV 1 will prompt that the near-field voice function (such as voice recognition function) cannot be activated during the karaoke process.

[0123] Alternatively, the remote control can detect whether it has received a Near_mic_start or Near_mic_stop command. If it has received a Near_mic_start or Near_mic_stop command, it will not process it and will continue to collect singing voice data.

[0124] 7. During the transmission of singing voice data, the remote control checks whether it receives the second control information sent by the TV, such as a volume adjustment command. If the remote control receives the volume adjustment command, it adjusts the volume gain according to the volume value of the volume adjustment command.

[0125] 8. To prevent the remote control from continuously collecting singing voice data, which would increase its power consumption, the voice playback method provided in this disclosure requires the TV 1 to periodically send a collection command to the remote control. If the remote control does not receive the collection command within the current period, it will stop collecting singing voice data; if it receives the collection command within the current period, it will continue collecting singing voice data. For example, the remote control checks whether it has received a collection command within 20 seconds. If the collection command is "Karaoke_mic_start", and the remote control receives the "Karaoke_mic_start" command within 20 seconds, it updates the timeout and maintains the karaoke function.

[0126] 9. When the remote control receives the Karaoke_mic_stop signal from TV 1, it stops collecting singing voice data, that is, the remote control turns off the power supply to the microphone.

[0127] 10. The remote control clears the buffer of singing voice data. To ensure the underlying buffer data of the chip is completely cleared, the remote control performs other operations only after a target time has elapsed, such as 20ms.

[0128] 11. The remote control sends Karaoke_voice_stop to TV 1 to indicate that the remote control has exited the karaoke function (i.e., stopped collecting singing voice data).

[0129] In some feasible examples, combining Figure 6 ,like Figure 7 As shown, the voice playback method provided in this embodiment of the disclosure further includes: S17-S19.

[0130] S17. If the first priority is lower than the second priority, send a third control message to the control device to instruct the collection of singing voice data to stop and to enable the near-field voice function.

[0131] S18. Receive near-field voice data sent by the control device; wherein the sampling rate of the near-field voice data is a second sampling rate, which is less than the first sampling rate.

[0132] In some examples, when users use singing applications to sing, they have high requirements for the quality and transmission latency of the singing voice data. The existing voice formats are no longer sufficient for singing. Therefore, the sampling rate, transmission interval, and data packet size in the voice format can be adjusted to ensure that the transmission latency of the singing voice data meets the requirements for singing. For example:

[0133] 1. Sampling rate: Increase the sampling rate from the second sampling rate (e.g., 16kHz) to the first sampling rate (e.g., 32kHz). Increasing the sampling rate increases the amount of speech data in the same time period, and the data quality is improved accordingly.

[0134] 2. Transmission interval: The transmission interval has been reduced from the first preset duration (e.g., 20ms) to one packet (divided into two smaller packets and sent twice), to the second preset duration (e.g., 10ms). The voice transmission interval has also been changed from the default third preset duration (e.g., 20ms) to the fourth preset duration (e.g., 10ms). This reduces the voice transmission delay. Combined with optimizations on the TV, the transmission delay for singing using the remote control can now be kept below 100ms.

[0135] 3. Data packet size: Large packet transmission is adopted. Each target duration (e.g., 10ms) of voice data is composed of a large packet and transmitted after compression. The overall length of the data packet is a preset length (e.g., 42 bytes), and the data transmission adopts a compression algorithm with a preset multiple (e.g., 16 times).

[0136] The data packet consists of: Report ID, Frame NO., and voice data.

[0137] HID report ID: 0xF7

[0138] FrameNO.: The sequence number of the loop from 0x00 to 0xFF.

[0139] For example, the format of singing voice data is shown in Table 7.

[0140] Table 7

[0141]

[0142] S19. Generate prompt information for the text data corresponding to the near-field speech data.

[0143] For example, when the first priority is lower than the second priority, the interaction process between the TV 1 and the remote control includes:

[0144] 1. TV 1 sends Karaoke_mic_start to remote control, and remote control receives the Karaoke_mic_start command sent by TV 1.

[0145] 2. Use the remote control to start the hardware, turn on the microphone (MIC), and power it on.

[0146] 3. The remote control begins collecting singing voice data. After the remote control powers the microphone, the microphone will begin collecting singing voice data. At this time, the microphone may pick up noise from button presses and sounds of microphone instability. Therefore, after the remote control powers the microphone, a preset delay can be set before starting the collection of singing voice data. For example, the preset delay could be 100ms.

[0147] 4. The remote control sends the Karaoke_voice_start command to TV 1.

[0148] 5. The remote control transmits the collected singing voice data to TV 1. For example, the data packet format of the singing voice data can be 42 bytes in length, with singing voice data in large packets every 10ms, compressed and transmitted.

[0149] 6. During the transmission of singing voice data, the remote control needs to determine whether there are any operations or commands that conflict with the karaoke function. For example, the remote control checks if a voice button is pressed. If so, the remote control exits the karaoke function and sends "Karaoke_voice_stop" to TV 1. Simultaneously, the remote control sends the key value corresponding to the voice button to TV 1, switches the sampling rate from the first sampling rate to the second sampling rate (e.g., 16kHz), and activates the near-field voice function. When the pressed voice button is released, the remote control disables the near-field voice function. Afterward, if the remote control receives the first control information from TV 1 again, such as "Karaoke_mic_start," the remote control will resume collecting singing voice data at the first sampling rate.

[0150] Alternatively, the remote control can detect if any buttons other than the voice button are pressed. If other buttons are pressed, the remote control sends the key value corresponding to those other buttons to TV 1, while the remote control continues to collect singing voice data.

[0151] Alternatively, the remote control detects whether it has received the Near_mic_start command. If it does, the remote control sends a Near_voice_start response and switches the sampling rate from the first sampling rate to the second sampling rate. For example, if the second sampling rate is 16kHz, the near-field voice function is activated. After receiving the Near_mic_stop command from TV 1, the remote control exits the near-field voice function and turns off the microphone (i.e., stops powering the microphone). Afterward, if the remote control receives the first control information from TV 1 again, such as Karaoke_mic_start, the remote control will start collecting singing voice data again according to the first sampling rate.

[0152] Alternatively, the remote control can detect whether it has received a Near_mic_stop command. If the remote control receives a Near_mic_stop command sent by TV 1, it will not perform any processing and will continue to collect singing voice data.

[0153] 7. During the transmission of singing voice data, the remote control checks whether it receives the second control information sent by the TV, such as a volume adjustment command. If the remote control receives the volume adjustment command, it adjusts the volume gain according to the volume value of the volume adjustment command.

[0154] 8. To prevent the remote control from continuously collecting singing voice data, which would increase its power consumption, the voice playback method provided in this disclosure requires the TV 1 to periodically send a collection command to the remote control. If the remote control does not receive the collection command within the current period, it will stop collecting singing voice data; if it receives the collection command within the current period, it will continue collecting singing voice data. For example, the remote control checks whether it has received a collection command within 20 seconds. If the collection command is "Karaoke_mic_start", and the remote control receives the "Karaoke_mic_start" command within 20 seconds, it updates the timeout and maintains the karaoke function.

[0155] 9. When the remote control receives the Karaoke_mic_stop signal from TV 1, it stops collecting singing voice data, that is, the remote control turns off the power supply to the microphone.

[0156] 10. The remote control clears the buffer of singing voice data. To ensure the underlying buffer data of the chip is completely cleared, the remote control performs other operations only after a target time has elapsed, such as 20ms.

[0157] 11. The remote control sends Karaoke_voice_stop to TV 1 to indicate that the remote control has exited the karaoke function (i.e., stopped collecting singing voice data).

[0158] In some feasible examples, combining Figure 4 ,like Figure 8 As shown, before executing S11, the voice playback method provided in this embodiment of the disclosure further includes: S20-S22.

[0159] S20. Upon receiving upgrade information for upgrading the control device, send fourth control information containing the upgrade information to the control device and disconnect the pairing relationship with the control device; wherein, the fourth control information is used to instruct the control device to upgrade according to the upgrade information so that the control device has far-field voice acquisition function, and at the same time disconnect the pairing relationship.

[0160] S21. Receive pairing broadcast information sent by the control device;

[0161] S22. Based on the pairing broadcast information, re-establish the pairing relationship with the control device and send the fifth control information indicating that the pairing relationship has been re-established to the control device.

[0162] In some cases, to enable existing remote controls to support new features (such as karaoke functionality), an Over-the-Air (OTA) upgrade is required. The upgraded remote control then reconnects to the TV without needing to be re-paired. However, this reconnection process cannot support the synchronization of new features (such as Report ID), so even if the upgrade is successful, the karaoke function will not be usable. Therefore, the audio playback method provided in this embodiment automatically clears the pairing information after the remote control completes its OTA upgrade and sends a pairing broadcast packet within a preset time (e.g., 30 seconds) (the packet is sent until the 30-second timeout ends or the remote control is successfully paired with TV 1 again, to avoid the remote control remaining in a high-power state for a long time due to unsuccessful pairing); after receiving the broadcast packet sent by the remote control indicating that the OTA upgrade has been completed, the driver layer of TV 1 unpairs the device and sends a depairing broadcast to the upper application layer after depairing is completed; upon receiving the depairing broadcast, the application layer of TV 1 starts a pairing scan and continues for a specified time (e.g., 1 minute) to avoid the service being kept on for a long time if no pairing broadcast packet is detected and pairing is not completed, which would affect the TV's WiFi throughput and memory usage; after the application layer of TV 1 detects the pairing broadcast from the remote control, it initiates a pairing process, completes the pairing, and sends a fifth control message indicating that the pairing relationship has been re-established to the control device.

[0165] S32. Collect singing voice data according to the first sampling rate;
