In complex and ever-changing outdoor environments, the limited interface resources of live streaming equipment struggle to simultaneously meet the dual demands of continuous power supply and high-speed data streaming.
[0003] Live streaming equipment consumes a lot of power during broadcasts, and ordinary docking stations cannot provide sufficient output power to maintain normal operation. Existing solutions for data streaming between live streaming equipment and computers rely on multiple chips working together, resulting in a complex system architecture, cumbersome connection methods, and significantly increased hardware costs. Furthermore, the streaming stability and transmission efficiency of current solutions still need optimization. Therefore, ensuring stable power supply and efficient data streaming for live streaming equipment simultaneously is a pressing issue that needs to be addressed. Summary of the Invention
[0004] In view of the above-mentioned shortcomings of the prior art, this application provides a power supply and streaming synchronization system for live streaming equipment and live streaming equipment, which effectively solves the problem that live streaming equipment cannot simultaneously provide stable power supply and efficient data streaming.

Detailed Implementation
[0019] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be further described clearly and completely below with reference to the accompanying drawings of the embodiments. It should be noted that the described embodiments are merely some embodiments of this application, and not all embodiments.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.
[0022] In outdoor live streaming applications, live streaming equipment often needs to be connected to an external power source simultaneously to ensure continuous power supply and establish a stable connection with the streaming device. However, the current single-interface design architecture of live streaming equipment is insufficient to meet this complex functional requirement, resulting in the inability to achieve synchronous operation of power supply and data transmission in complex application scenarios. Existing Type-C docking station solutions have the following technical limitations: First, their multi-functional integration capabilities are insufficient, making it difficult to simultaneously achieve core functions such as high-power power supply and high-speed data transmission, which is significantly different from the increasingly diversified usage needs of users. Second, limited by power output specifications, ordinary docking stations cannot provide a continuous and stable power supply for high-power-consuming live streaming equipment. Third, existing solutions rely on the collaborative work of multiple chips to realize the data streaming function between the live streaming machine and the computer, which not only leads to complex connection topologies and increased PCB layout area, but also significantly increases system cost and design complexity. In addition, traditional docking stations adopt a single-mode architecture, with all interfaces sharing the same data bus. When a single peripheral experiences compatibility issues, it will cause system-level stability risks. This design flaw seriously restricts the reliability and transmission efficiency of live streaming.
[0023] Example 1 This application provides a power supply and streaming synchronization system for live streaming equipment, which effectively solves the problem that live streaming equipment cannot simultaneously achieve stable power supply and efficient data streaming. Figure 1 This is a first schematic diagram of the power supply and streaming synchronization system structure of the live streaming equipment provided in this application embodiment, as shown below. Figure 1As shown, the power supply and streaming synchronization system 100 of the live streaming equipment is applied to the live streaming equipment, which includes a multi-functional integrated interface connector 210. The power supply and streaming synchronization system 100 of the live streaming equipment includes a first interface connector 110, a second interface connector 120, a third interface connector 130, a data interface expansion module 140, and a power management chip 150.
[0024] In this embodiment, the first interface connector 110 is connected to the multi-function integrated interface connector 210. Optionally, the multi-function integrated interface connector 210 is the female connector of the live streaming device 200, which can be a full-function Type-C female connector for connecting external devices and adapters, etc., and the first interface connector 110 can be a Type-C male connector for connecting the live streaming device 200.
[0025] The high-speed data signal line of the first interface connector 110 is directly connected to the second interface connector 120, forming a high-speed signal pass-through path. The second interface connector 120 can be a Type-C female connector, and the high-speed data signal line can be, for example, a USB 3.0 or higher ultra-high-speed data line.
[0026] In this embodiment, all non-USB 2.0 signals of the first interface connector 110, such as USB 3.0, USB 3.1 high-speed data lines, and CC lines, are directly connected to the corresponding signal lines of the second interface connector 120. When a high-speed streaming device is connected to the second interface connector 120, the data stream does not need to pass through any conversion chip and communicates directly with the live streaming device, achieving minimal latency.
[0027] This application embodiment ensures the purity of the core video streaming data path through high-speed signal pass-through design and lossless signal transmission, minimizing signal attenuation and latency, which is crucial for live streaming quality and smoothness.
[0028] As an optional implementation of this application, since the first interface connector 110 and the second interface connector 120 are directly connected, impedance matching needs to be considered. To achieve lossless transmission of USB 3.0 and higher high-speed data signals within the system and ensure low latency, high bandwidth, and high stability during video streaming, strict physical layer design specifications and electromagnetic compatibility optimization strategies are adopted for the high-speed signal pass-through path.
[0029] First, regarding signal integrity, all traces used for transmitting ultra-high-speed differential signals strictly adhere to the differential impedance matching principle, setting the target differential impedance to 90Ω±10%. This impedance value is consistent with the characteristic impedance of the Type-C interface and related high-speed devices, effectively avoiding signal reflection, ringing, and overshoot caused by impedance mismatch, thereby significantly reducing the bit error rate and ensuring reliable data link establishment and continuous communication.
[0030] Secondly, to maintain the timing consistency of differential signals and suppress the generation of common-mode noise, the internal trace lengths of key high-speed differential pairs must be strictly controlled to be equal, with a deviation not exceeding ±5mm. This equal-length design reduces the propagation delay differences between differential signals, prevents eye diagram closure caused by phase shift, and thus improves the signal sampling accuracy of live streaming equipment.
[0031] Furthermore, all high-speed signal traces should have their total path length minimized, prioritizing the shortest direct-connection topology to reduce high-frequency attenuation and group delay during transmission. Especially for USB 3.0 and higher signals operating in the GHz band, excessively long traces introduce significant insertion loss and dispersion effects, impacting signal integrity. Therefore, in this embodiment, the high-speed signal path between the first interface connector 110-C male and the second interface connector 120 is designed as a point-to-point direct connection, without any active or passive conversion chips in between, preserving the original signal quality to the maximum extent.
[0032] At the PCB layout level, a complete and continuous reference ground plane should be maintained beneath high-speed data signal lines, and it must not be interrupted by other signal lines or power traces. A complete ground plane not only provides a stable return path for differential signals, but also effectively suppresses crosstalk and electromagnetic radiation, improving anti-interference capabilities. At the same time, high-speed data signal traces should be kept away from high-noise sources, including but not limited to switching power supply modules, clock oscillators, high-current power lines, and PCB edges, to prevent electromagnetic coupling interference.
[0033] Furthermore, to enhance the system's electromagnetic shielding performance and electrostatic discharge protection capabilities, the metal housings of the first interface connector 110 and the second interface connector 120 are connected to the main grounding layer of the PCB through multiple evenly spaced grounding vias with low impedance, forming a three-dimensional Faraday cage shielding structure. This multi-point grounding method can effectively dissipate high-frequency interference energy, suppress the intrusion of external electromagnetic interference, and also improve the equipment's tolerance to external electrostatic events.
[0034] Finally, in this embodiment, transient voltage suppression diodes can be configured on the data lines and power lines of the first interface connector 110, the second interface connector 120, and the third interface connector 130. These transient voltage suppression diodes have fast response and high surge absorption capabilities, and can quickly clamp the voltage and protect sensitive downstream integrated circuits from damage when electrostatic discharge from a human body, live cable insertion or removal, or other transient overvoltage events occur. The selection of transient voltage suppression diodes can comprehensively consider parameters such as operating voltage, breakdown voltage, clamping voltage, and junction capacitance to ensure that they provide sufficient ESD protection without affecting high-speed signal transmission.
[0035] The embodiments of this application, from impedance control and wiring specifications to shielding and protection design measures, together constitute a highly reliable signal transmission architecture for high-performance live streaming application scenarios.
[0036] The low-speed data signal line of the first interface connector 110 is connected to the data interface expansion device, which is connected to the second interface connector 120 and the third interface connector 130 respectively.
[0037] Optionally, the low-speed data signal line can be a USB 2.0 data signal line, the data interface expansion device can be a HUB chip, and the third interface connector 130 can be a Type-C female connector. The USB 2.0 data signal line of the first interface connector 110 is connected to a HUB chip, which expands one USB 2.0 signal into two. The first output is connected to the USB 2.0 signal pin of the third interface connector 130, and the second output is connected back to the USB 2.0 signal pin of the second interface connector 120.
[0038] The second interface connector 120 connects to the live streaming device and is used to transmit both high-speed and low-speed data signals. As a versatile port, the second interface connector 120 supports both high-speed pass-through data and low-speed split-through data. The third interface connector 130 can transmit USB 2.0 signals and can also connect to USB 2.0 devices with low bandwidth requirements, such as keyboards, mice, and audio devices.
[0039] The third interface connector 130 is connected to the power management chip 150, which is used to negotiate a power transmission protocol with the live streaming equipment so that the third interface connector 130 can receive external power input and supply power to the live streaming equipment.
[0040] The embodiments of this application physically and logically isolate high-speed data transmission, low-speed data transmission, and power management, avoiding resource contention and mutual interference when sharing a single channel, resulting in higher overall system efficiency.
[0041] As an optional implementation of this application, the power management chip 150 can be a CH224K chip. This CH224K chip configures its pin states according to a preset voltage to request a fast-charging voltage from the live streaming device. The CC configuration channel pin of the third interface connector 130 is connected to the CC pin of the power management chip 150, and the port of the third interface connector 130 is the preferred power input port. When the charger is connected to the third interface connector 130, the CH224K chip negotiates a power transfer protocol with the live streaming device through its CC pin, automatically requesting and establishing a suitable fast-charging voltage and current to efficiently power the live streaming device.
[0042] For example, Figure 2 This is a schematic diagram of the pin configuration of the CH224K chip in an embodiment of this application, as shown below. Figure 2 As shown, the CH224K chip has three power level configuration input pins CFG1, CFG2, and CFG3. Different voltage level combinations are configured through these pins to set the output voltage level under the power transfer protocol, including but not limited to at least one of 5V, 9V, 12V, 15V, and 20V. Connecting the input pin to VDD is 1, and ground is 0. When CFG1 is 1, the requested voltage is 5V; when CFG1, CFG2, and CFG3 are 0, the requested voltage is 9V; when CFG1 and CFG2 are 0 and CFG3 is 1, the requested voltage is 12V; when CFG1 is 0 and CFG2 and CFG3 are 1, the requested voltage is 15V; and when CFG1 and CFG3 are 0 and CFG2 is 1, the requested voltage is 20V.
[0043] This application provides intelligent and fast charging protection. The independent power negotiation channel third interface connector 130 and CH224K chip ensure that the live broadcast equipment can obtain the best charging power under any data load, solving the power problem of live broadcasting and charging at the same time.
[0044] As a further implementation of the embodiments of this application, Figure 3 This is a second schematic diagram of the power supply and streaming synchronization system structure of the live streaming equipment provided in this application embodiment, as shown below. Figure 3 As shown, the power supply and streaming synchronization system 100 of the live streaming equipment also includes a DC-DC power chip 160. This DC-DC power chip 160 is connected to both the power management chip 150 and the data interface expansion module 140. The DC-DC power chip 160 converts the input voltage of the external power supply into the operating voltage required by the data interface expansion module 140. This power management path is independent of the data signal path, ensuring the focus and stability of the charging process and preventing the HUB chip from failing to function due to a lack of power supply branches.
[0045] As an optional implementation of this application, the power supply and streaming synchronization system 100 of the live streaming device further includes an analog switch chip 170, which is disposed in the live streaming device and connected to a multi-functional integrated interface connector. The analog switch chip 170 is used to switch the high-speed data signal path according to control commands.
[0046] In this embodiment, when a live streaming device is connected to an external streaming device, data transmission relies on the multiple differential signal channels supported by the Type-C interface. Because the Type-C interface is reversible and its pins are symmetrically distributed physically, differential signals of different rate levels must be processed differently to ensure correct signal connection and functional compatibility regardless of how the device is plugged in. The USB 2.0 differential signals on both sides of the Type-C interface are connected, meaning they are the same signal. However, USB 3.0 signals are high-speed signals and cannot be transmitted in the same way as USB 2.0 signals. The high-speed USB 3.0 signal output by the live streaming device is split into two paths when it reaches the Type-C interface, affecting signal quality. The analog switch chip 170 can connect the physical pins on the multi-function integrated interface connector to different internal differential pairs according to the control instructions of the control module, selecting among multiple signal paths and accurately transmitting the signal to the high-speed data signal path.
[0047] As an optional implementation of this application, the power supply and streaming synchronization system 100 of the live streaming device further includes a power transmission controller 180. The power transmission controller 180 is disposed in the live streaming device and is connected to a multi-functional integrated interface connector. The power transmission controller 180 is used to detect the connection status of the live streaming device and negotiate the power transmission protocol with the external power supply to coordinate the high-speed data signal path and power supply mode.
[0048] In this embodiment, the power transmission controller 180 can accurately determine whether an external device is inserted, its insertion direction, and the type of the connected device by monitoring the voltage changes of the CC pins in the second interface connector 120 and the third interface connector 130. Since high-speed signals of USB 3.0 and above cannot achieve reversible communication through simple parallel connection like USB 2.0, path selection must rely on the analog switch chip 170. The operation logic of the analog switch chip 170 is triggered by the connection status information provided by the power transmission controller 180. For example, the power transmission controller 180 transmits the detected insertion direction and device type information to the control module. Based on this, the control module controls the analog switch chip 170 to conduct the corresponding differential channel, ensuring that the high-speed signal flows only to the currently effective physical interface side, avoiding impedance mismatch and transmission degradation caused by signal splitting.
[0049] The power transmission controller 180 can also digitally communicate with an external power adapter or power supply terminal to negotiate the optimal power supply voltage and current level to meet the high-power charging needs of live streaming equipment under high load conditions.
[0050] In this embodiment, based on the real-time monitoring of the connection status of the second interface connector 120 and the third interface connector 130 by the power transmission controller 180, the system can automatically identify and enter different operating modes without manual configuration by the user. Specifically, the system's operating states include the following: The second interface connector 120 is not connected, and the third interface connector 130 is connected to the power adapter to power the live streaming equipment; the third interface connector 130 is not connected, and the second interface connector 120 is connected to the power adapter to power the live streaming equipment.
[0051] The second interface connector 120 is not connected, the third interface connector 130 is connected to the streaming device, and the live streaming device and the streaming device perform USB 2.0 signal data streaming; the third interface connector 130 is not connected, the second interface connector 120 is connected to the streaming device, and the live streaming device and the streaming device perform USB 2.0 signal and USB 3.0 signal data streaming.
[0052] The third interface connector 130 connects to the power adapter, the second interface connector 120 connects to the streaming device, the third interface connector 130 supplies power to the live streaming device, and the live streaming device and the streaming device stream data via USB 2.0 and USB 3.0 through the second interface connector 120.
[0053] The second interface connector 120 connects to the power adapter, and the third interface connector 130 connects to the streaming device. The second interface connector 120 supplies power to the live streaming device, and the live streaming device and the streaming device stream USB 2.0 signal data through the third interface connector 130.
[0054] The embodiments of this application greatly improve the ease of use and scenario adaptability of the system through automated and intelligent mode switching capabilities, ensuring stable power supply even during high-intensity data streaming, thereby improving the user experience.
[0055] The power supply and streaming synchronization system for live streaming equipment provided in this application combines a physical connection topology with a dedicated chip to decouple and optimize signals and power from the live streaming equipment. High-speed data signal paths are isolated and directly connected to the live streaming equipment and the streaming device, ensuring transmission efficiency and stability. Low-speed signals such as USB 2.0 are properly distributed through a HUB chip, enabling reliable connection and management of multiple low-speed devices and preventing interference with the high-speed channel. A dedicated power management chip independently manages power negotiation at the charging port, ensuring the live streaming equipment receives a fast and stable power supply.

Figure 4This is a schematic diagram of the live streaming device connection provided in an embodiment of this application, such as... Figure 4 As shown, the live streaming equipment adopts the power supply and streaming synchronization system 100 of the live streaming equipment in Embodiment 1. The live streaming equipment 200 is connected to the power supply and streaming synchronization system 100 of the live streaming equipment, and the power supply and streaming synchronization system 100 of the live streaming equipment is connected to the streaming equipment 300 and the external power supply 400 respectively.
[0057] The live streaming device provided in this application embodiment can achieve stable and reliable uninterrupted live streaming. The integrated design reduces size and power consumption, and provides a high level of connection reliability, power supply flexibility and ease of operation in complex and ever-changing outdoor scenarios, effectively improving live streaming quality and user experience.
[0058] It is understood that the implementation method in the power supply and streaming synchronization system of the live streaming equipment in Embodiment 1 above is also applicable to this embodiment and can achieve the same technical effect, so it will not be described again here.
[0059] In summary, the power supply and streaming synchronization system and live streaming equipment provided in this application significantly improve the power supply reliability and data streaming stability of live streaming equipment in multiple scenarios through a collaborative architecture of high-speed signal direct connection, low-speed signal splitting, and independent power negotiation. High-speed signals directly connect the live streaming equipment and the streaming device, avoiding delays and losses caused by protocol conversion and ensuring the real-time performance and integrity of high-definition video transmission. Low-speed signals are properly split through the data interface expansion module, supporting multiple peripheral accesses without interfering with the high-speed channel. The power management chip independently negotiates power transmission protocols through a dedicated control channel, ensuring stable and efficient power supply during simultaneous broadcasting and charging.
