Abstract
Description
Technical Field
[0001] This application relates to the field of live streaming technology, and in particular to a multifunctional handheld device and a live streaming system. Background Technology
[0002] A live streaming system is an all-in-one device used to transmit audio and video content to an online platform in real time. It integrates multiple functions such as camera, audio and video capture, image processing, network transmission, streaming, and operation control. Its core components include a high-quality video recording unit for capturing clear and stable images; a professional audio capture unit to ensure clear and nuanced sound during live streaming; and a powerful hardware or software streaming system for encoding, compressing, and transmitting the real-time captured audio and video signals to the network platform.
[0003] Traditional monocular live streaming cameras can only provide a single two-dimensional image, resulting in relatively simple visual effects. When displaying three-dimensional scenes or objects, they lack a realistic sense of depth and three-dimensionality. Even with post-processing techniques that can enhance the image's layering to some extent, it still falls short compared to the effect of a binocular camera. Binocular live streaming cameras can simulate the human binocular visual system, making captured photos or videos more realistic and three-dimensional, giving viewers a stronger sense of immersion. Especially when live streaming scenes that require a sense of space, such as outdoor landscapes or large-scale events, binocular cameras can better present the overall view and spatial layout of the scene.
[0004] During live streaming, the operation and control of the live streaming device is crucial. Traditional control methods mostly rely on the physical buttons on the device itself, the user interface (UI), or an external keyboard and mouse, resulting in poor operational flexibility and limited applicability. This control method is insufficient when the broadcaster needs to move around a large area or is in a position where it's inconvenient to approach the device. Therefore, remote control handles have gradually been adopted in the field of live streaming device control; however, existing remote control handles have relatively limited functionality and cannot meet the diverse operational needs during live streaming.

[0024] Example 1 This application provides a multi-functional handle device that enables remote control, power supply, and data transmission of the live streaming device, thereby improving the convenience and practicality of live streaming operations.
[0025] See Figure 1 The multi-functional handle device 100 includes: a main control module 110, a button control module 140, a wireless communication module 120, a data transmission module 150, a power supply module 130, and a Type-C interface (…). Figure 1 (Not shown). The main control module 110 is connected to the button control module 140, the wireless communication module 120, the data transmission module 150, the power supply module 130, and the Type-C interface.
[0026] In this embodiment, the main control module 110 is used to receive the operation instructions from the button control module 140, parse and process the operation instructions, and obtain control signals. The wireless communication module 120 is used to send the control signal to the live streaming device to control the live streaming device to perform corresponding operations; The power module 130 is connected to the Type-C interface, and the power module 130 is used to supply power to the live streaming device through the Type-C interface; The data transmission module 150 is connected to the Type-C interface, and the data transmission module 150 is used to perform bidirectional data transmission with the live streaming device through the Type-C interface.
[0027] The multi-functional handle device 100 provided in this embodiment combines a remote control handle with a power supply function. It can not only expand the function of the remote control handle, but also effectively solve the problem of battery life of the live broadcast device. During the live broadcast, it can realize the two-way data transmission of shooting data, device status and other information in real time, and meet the data interaction needs during the live broadcast.
[0028] In this embodiment, the multi-functional handle device 100 enables remote multi-functional control of the live streaming device 200, including but not limited to adjusting shooting parameters, switching images, and monitoring device status; it also provides a stable power supply to the live streaming device, extending its battery life; and establishes a stable and fast data transmission channel to enable data interaction between the handle device and the live streaming device, thereby improving the overall performance of the live streaming device and the convenience of live streaming operation.
[0029] See Figure 2 The multi-functional handle device 100 and the live streaming device 200 establish a wireless communication connection. See [link / reference] Figure 3 The live streaming device 200 includes a binocular heterogeneous camera module 210, a circuit motherboard 220, a display screen 230, an audio module 240, a wireless communication module 250, a control board 260, and a three-axis gimbal 270. The binocular heterogeneous camera module 210 includes a main camera 211 and a secondary camera 212. It should be noted that the live streaming device 200 can be a miniaturized binocular camera live streaming device, and the multi-functional handle device 100 and the live streaming device 200 can constitute a live streaming system.
[0030] During indoor live streaming, the multi-functional handle device 100 is easy to operate, enabling quick and accurate control of the live streaming equipment. Data transmission is stable and fast, meeting the needs for material transmission during live streaming. The power supply function of the multi-functional handle device 100 effectively ensures the long-term operation of the live streaming equipment, preventing interruptions due to insufficient power, thus improving the quality and efficiency of indoor live streaming.
[0031] In this embodiment, the wireless communication module 120 includes a Bluetooth module and a WIFI module. After connecting to the live broadcast machine via the Bluetooth module and the WIFI module, a control channel between devices is established through the wireless network, and the received digital signals are converted into control signals that can be recognized by the controlled device.
[0032] During outdoor live streaming, the multi-functional handle 100 performed well in complex outdoor environments. Flexible switching between Wi-Fi and Bluetooth dual-mode wireless communication ensured stable transmission of control signals. The multi-functional handle 100's power supply and long battery life enabled the live streaming device to operate stably outdoors for extended periods. Various operations performed using the multi-functional handle 100 were accurate and efficient, effectively improving the quality and stability of outdoor live streaming and meeting diverse outdoor live streaming needs.
[0033] In this embodiment, the button control module 140 includes multiple function buttons, each function button corresponding to a general purpose input / output interface (GPIO). The main control module 110 is connected to each of the general-purpose input / output interfaces and is used to detect the high and low level changes of each of the general-purpose input / output interfaces and use the detected high and low level change signals as the operation commands.
[0034] It should be noted that the button control module uses an independent button connection method, with different buttons corresponding to different GPIOs. By detecting changes in the high and low levels of the GPIOs and transmitting the data to the ARM main controller, the corresponding control is achieved.
[0035] In this embodiment, the button control module 140 includes a multi-functional composite button; the multi-functional composite button is used to generate a power-on command based on a single short press operation in the power-off state, generate a shooting command based on a single short press operation in shooting mode, generate a power-off and restart selection interface based on a first long press operation, and generate a forced power-off command based on a second long press operation, wherein the duration of the second long press operation is longer than that of the first long press operation. The main control module 110 is used to start the multi-functional handle device according to the power-on command and to turn off the multi-functional handle device according to the forced power-off command. The wireless communication module 120 is used to send the shooting command to the live streaming device 200.
[0036] In one embodiment, the button control module further includes a screen switching button and a zoom adjustment button; The screen switching key is used to generate a screen switching command based on the first pressing operation; The zoom adjustment key is used to generate a zoom adjustment command based on the second pressing operation; The wireless communication module is used to send the screen switching command and the zoom adjustment command to the respective live streaming device.
[0037] Additionally, the power / shoot button serves as both the power on / off and shooting button, the screen switching button is used for screen switching, and the zoom adjustment button is used for adjusting the focus. As an example, the power / shoot button is a multi-function button: a short press in the off state powers on, a short press in shooting mode shoots, a 5-second press brings up the power off / restart selection interface, and an 8-second press forces a shutdown. When a button is pressed / released, the main control detects level changes via GPIO interrupts or polling, and confirms a valid action based on the anti-shake delay (usually 10-20ms), directly mapping it to the "button pressed" or "button released" command. The buttons on the multi-function handle are waterproof and dustproof, offering good tactile feedback and durability. Furthermore, the multi-function handle also includes a joystick for controlling the direction and angle of the live streaming camera's three-axis gimbal.
[0038] In another embodiment, the button control module further includes: The joystick is used to control the motion parameters of the three-axis gimbal of the live streaming device.
[0039] In one embodiment, the Type-C interface includes a Type-C male connector and a Type-C female connector, the Type-C male connector being disposed on the top surface of the multi-functional handle, and the Type-C female connector being disposed on the bottom surface of the multi-functional handle; The Type-C male connector is connected to the live streaming device and is used to supply power to the live streaming device and transmit data. The Type-C female connector is connected to an external device for charging the power module and transmitting data with the external device.
[0040] It should be noted that the multi-function button can also function as a power / shooting button; see [link / reference]. Figure 4 A power / shooting button 410 is located on one side of the multi-functional handle. The multi-functional handle is ergonomically designed for easy grip and portability. The handle shell is made of high-strength, lightweight engineering plastic, providing good wear resistance and slip resistance. The internal components of the multi-functional handle mainly include a main control module 110, a button control module 140, a wireless communication module 120, a data transmission module 150, and a power module 130, among other functional modules. These modules are electrically connected via a circuit board.
[0041] See Figure 5 The multi-functional handle includes a Type-C female connector 450, a Type-C male connector 410, a screen switching button 430, a zoom adjustment button 440, and a joystick 420. The Type-C male connector 410 is located on the top surface of the multi-functional handle, the Type-C female connector 450 is located on the bottom surface, and the screen switching button 430, zoom adjustment button 440, and joystick 420 are located on the other side. The Type-C male connector 410 is used to connect to the live streaming device, enabling the multi-functional handle to power the live streaming device and transmit data. The Type-C female connector 450 is used to connect to external devices for charging and data transmission.
[0042] In one embodiment, the wireless communication module includes a Bluetooth module; The Bluetooth module is used to filter target devices, initiate pairing requests to the target devices, receive pairing responses from the target devices, establish temporary LMP links based on the pairing responses, determine pairing parameters, and determine whether the authentication of the target devices is successful based on the pairing parameters; if the authentication is successful, a long-term key is generated; the device address of the target devices, the long-term key, and the configuration information of the target devices are stored; and encrypted communication is established between the multi-function controller and the target devices.
[0043] Additionally, the Bluetooth module enables rapid and stable pairing between the multi-functional handle and the live streaming device, suitable for control scenarios within a short distance of 10 meters. The WiFi module supports 2.4GHz and 5GHz bands, enabling high-speed data transmission over longer distances and distances exceeding 10 meters, meeting the needs for control and data interaction of the live streaming device over a wider area. Bluetooth pairing allows for rapid pairing; after storing the target device's device address, long-term key, and configuration information, subsequent reconnections automatically match the stored information for a fast and encrypted connection.
[0044] The wireless communication module enhances signal strength and transmission capability through a compatible antenna, ensuring stable transmission of control signals and data. It can also acquire status information such as the controller's battery level and temperature, sending this information to the main unit of the live streaming device.
[0045] In this embodiment, the following hardware-level improvements were made to ensure stable Bluetooth module connectivity: Antenna design was upgraded with a diversity antenna (2.4GHz dual-antenna switching) and PCB impedance matching optimization (50Ω standard) to improve signal reception sensitivity and reduce connection fluctuations caused by distance attenuation; RF performance was enhanced by using a low-noise amplifier (LNA) and a high-efficiency power amplifier (PA) to increase transmit power and receive signal-to-noise ratio, extending the stable connection distance; Power supply and grounding were optimized with a low-ripple LDO power supply and an independent ground plane to avoid power supply noise interference with the RF circuit and reduce disconnections caused by unstable power supply. At the software level, the following improvements were made: 2.4GHz band conflicts were avoided by prioritizing clean channel transmission to reduce conflicts between devices on the same frequency and supporting device priority mechanisms; the reconnection mechanism was optimized by adding a fast reconnection cache (storing the LTK key and channel information of the most recently connected device), automatically initiating reconnection within 100ms after a disconnection to reduce perceived disconnection time; and scenario adaptation was implemented by customizing optimizations for specific usage scenarios, optimizing connection strategies in low-power mode to reduce power consumption while ensuring stable connectivity.
[0046] In one embodiment, the main control module is configured to send read commands to the coulomb counter and the temperature sensor respectively via the I2C protocol, read battery power information from the coulomb counter, and read battery temperature information from the temperature sensor; The wireless communication module is used to send the battery level and battery temperature to the live streaming device.
[0047] In this embodiment, the power module uses a high-energy-density rechargeable lithium battery, a 7.4V battery system, and a battery capacity of 1500mAh. The power module manages the charging and discharging of the controller battery through a charging management circuit, supports Type-C fast charging, and is compatible with various charging devices. The power module also has a power output interface, which connects to the Type-C female connector of the live streaming device via a standard Type-C male connector, providing a continuous and stable power supply to the live streaming device. Simultaneously, the power module has overcharge, over-discharge, and short-circuit protection functions to ensure the safety of the battery-powered controller.
[0048] In this embodiment, the Type-C high-speed data transmission protocol is used to achieve bidirectional data transmission and USB-PD fast charging between the multi-functional handle and the live streaming device. The data transmission module not only provides USB-PD fast charging but also transmits video data captured by the live streaming device in real time. For example, the live streamer can use the handle to quickly transfer captured footage to an external storage device for convenient post-editing and processing. When the battery is low, it can be quickly charged via the Type-C interface to replenish power.
[0049] In one embodiment, the power module includes a charging management circuit, which includes a power management chip, a battery, and a battery temperature sensor. The power management chip has a charging input pin for connecting to an external charging terminal, a voltage output pin for connecting to a load, and a battery pin for connecting to the positive terminal of the battery. The temperature detection input pin of the power management chip is used to connect to the temperature sensor.
[0050] Additionally, the battery power of the multi-functional handle device is obtained through charge integration measurement using a coulomb counter. By accurately measuring the charging and discharging current and accumulating the charge, combined with the battery's initial capacity and loss parameters, the remaining power is calculated. The battery's NTC (Negative Temperature Coefficient Thermistor) enables temperature monitoring and protection. Utilizing the characteristic that its resistance decreases with increasing temperature, it achieves safe temperature control during battery charging, discharging, and storage.
[0051] After obtaining the battery's power and temperature information, a read command is sent via the I2C protocol and the returned data is parsed. The parsed data is then sent to the live streaming device itself. This allows for real-time monitoring of the power and temperature information of the multi-functional handheld device, ensuring battery safety, optimizing device operation, extending battery life, and improving user experience.
[0052] In this embodiment, the charging management circuit uses a high-efficiency QFN4*4 packaged buck-boost battery and a power path management chip. It supports 1 to 4 lithium-ion / polymer batteries with a wide input voltage range. Its low-impedance power path optimizes efficiency, shortens battery charging time, and extends battery life. It supports USB-PD and OTG protocols and allows for flexible configuration via I2C communication.
