Description

Technical Field

[0001] This invention relates to the field of wireless communication and human-computer interaction technology, and in particular to a peripheral relay method and system for wireless display devices based on StarFlash communication. Background Technology

[0002] In current office and entertainment scenarios, users often face the problem of tangled cables. Monitors require video cables (HDMI / DP), keyboards and mice require USB cables, and USB flash drives need to be plugged into the back of the computer, resulting in a cluttered desktop. Although there are wireless keyboards and mice or Bluetooth audio devices, high-speed peripherals (such as webcams and external hard drives) still rely on wired connections.

[0003] Existing wireless display solutions (such as Miracast and Wi-Fi Direct) only transmit audio and video signals and do not support peripheral data relay; although some high-end monitors integrate USB hubs, they still need to be connected to the host via USB-B uplink cables, retaining a physical cable and failing to completely get rid of the constraints of cables.

[0004] NearLink's SLE mode boasts advantages such as ultra-low latency (<20μs), high reliability, and domestic production, providing a new path for wireless relay of peripherals. However, there is currently no technical solution to directly connect standard peripherals to a display and transparently relay them to a remote computing device via the NearLink link, allowing the operating system to seamlessly recognize them as locally connected devices. Summary of the Invention

[0005] The purpose of this invention is to provide a peripheral relay method and system for wireless display devices based on StarFlash Communication. The display completes the wireless relay transmission of peripheral data, enabling computing devices to achieve full-function interaction without physical connection to peripherals, thereby achieving the technical effect of zero desktop cables and a simple layout.

[0006] The technical solution adopted in this invention is:

[0007] A peripheral relay method for wireless display devices based on StarFlash communication includes the following steps:

[0008] Connect standard peripherals to wireless display devices;

[0009] The wireless display device performs local enumeration of standard peripherals and assigns local device addresses;

[0010] The wireless display device uses its integrated First Star Flash SLE communication module to encapsulate the data stream generated by the standard peripheral into a Star Flash adaptation protocol frame; the Star Flash adaptation protocol frame carries the USB transaction type and the local device address of the corresponding standard peripheral;

[0011] The StarSpark adaptation protocol frame is sent to the computing device via the StarSpark SLE wireless link;

[0012] The computing device uses its integrated second StarSignal SLE communication module to receive and parse StarSignal adapter protocol frames and restore them to standard USB transactions, so that the operating system of the computing device can recognize the standard peripheral as a local direct-connect device.

[0013] Furthermore, standard peripherals are directly connected to the physical peripheral interface of the wireless display device.

[0014] Furthermore, standard peripherals include keyboards, USB flash drives, 4K webcams, and NVMe external hard drives. Standard peripherals comply with USB, Bluetooth HID, UVC, or audio interface specifications and do not require support for StarFlash communication.

[0015] Furthermore, computing devices include, but are not limited to, desktop computers, laptops, servers, or tablets.

[0016] Furthermore, video signals between wireless display devices and computing devices are transmitted via independent wireless or wired links to separate them from standard peripheral data paths.

[0017] Furthermore, it also includes a wired backup mode: the wireless display device and the computing device are connected via a USB cable; when the StarFlash wireless link is interrupted or the signal quality deteriorates (such as packet loss rate > 5% or RSSI < -80dBm), the system automatically or manually switches to the wired connection via the USB cable, and transmits standard peripheral data to the computing device via the USB cable, and the USB cable does not carry video signals.

[0018] Specifically, the wired backup mode is an optional enhancement that depends on both devices having the corresponding interface and is not necessary to implement the basic functions of this invention.

[0019] The peripheral relay system for wireless display devices based on StarFlash Communication includes:

[0020] The wireless display device is equipped with a peripheral management unit and a first StarSignal SLE communication module. The peripheral management unit performs local USB enumeration on standard peripherals connected to the wireless display device, assigns local device addresses and endpoint numbers, and encapsulates the peripheral data stream into StarSignal adaptation protocol frames. The StarSignal adaptation protocol frames carry the USB transaction type and the local device address of the corresponding standard peripheral. The first StarSignal SLE communication module sends the StarSignal adaptation protocol frames to the target device (computing device) through the StarSignal wireless link.

[0021] The computing device has a built-in second StarShan SLE communication module and a virtual USB Host driver. The second StarShan SLE communication module is used to receive StarShan adaptation protocol frames through the StarShan wireless link; the virtual USB Host driver is used to parse the StarShan adaptation protocol and restore it to a standard USB transaction, so that the operating system can recognize the standard peripheral as a locally connected device.

[0022] Furthermore, the computing device also has a built-in NFC chip, and the wireless display device is equipped with an NFC pairing module; upon first use, the NFC-enabled computing device is touched to a designated area of ​​the display to exchange security credentials and establish a StarFlash SLE encrypted link to complete pairing.

[0023] Furthermore, the wireless display device is equipped with a USB-C interface, and the computing device is equipped with a corresponding USB-C or USB-A interface; the wireless display device is wired connected via a USB cable to form a wired path for relaying peripheral data in wired backup mode; the USB cable is used to transmit relay data of standard peripherals and does not carry video signals.

[0024] Furthermore, the wireless display device is a combination of a StarSpark docking station without a display panel and a standard monitor, with the standard monitor connected to the StarSpark docking station via an HDMI / DP interface.

[0025] The present invention, employing the above technical solution, has the following beneficial effects: 1) By directly connecting peripherals to the display device and utilizing the StarFlash link for data relay, all physical cables used for peripheral connections between the host and the display device are completely eliminated, fundamentally solving the desktop clutter problem and achieving an extremely simple layout. 2) Based on StarFlash SLE communication, the end-to-end latency between the display device and the computing device can be less than 100 microseconds, far superior to technologies such as Bluetooth and USB over IP. It can seamlessly support all types of USB peripherals, from low-speed keyboards and mice to high-speed cameras and external hard drives, meeting the needs of high-performance scenarios such as e-sports and professional drawing. Simultaneously, the operating system recognizes it as a local device, achieving true plug-and-play functionality without requiring any modification to existing software. 3) This invention combines the strong anti-interference characteristics of StarFlash technology itself with the introduction of a USB-C wired backup path, which can automatically switch when the wireless signal is weak, ensuring industrial-grade availability. Furthermore, the NFC touch pairing mechanism simplifies the initial setup process, greatly improving the user experience.

[0026] This invention connects standard peripherals directly to a wireless display device, which then wirelessly relays the data from these peripherals. This allows computing devices to achieve full-function interaction without the need for physical connections to peripherals, resulting in a streamlined desktop setup with no cables. It also provides an optional wired backup mechanism to ensure availability in extreme environments. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0032] like Figures 1 to 3 As shown in the figure, the present invention discloses a peripheral relay method for a wireless display device based on StarFlash communication, comprising the following steps:

[0033] Connect standard peripherals to wireless display devices;

[0034] The wireless display device performs local enumeration of standard peripherals and assigns local device addresses;

[0035] The wireless display device uses its integrated First StarSpeed ​​SLE communication module to encapsulate the data stream generated by the standard peripheral into a StarSpeed ​​adaptation protocol frame; the StarSpeed ​​adaptation protocol frame includes the transaction type, device address, endpoint number, and payload.

[0036] The StarSpark adaptation protocol frame is sent to the computing device via the StarSpark SLE wireless link;

[0037] The computing device uses its integrated second StarSignal SLE communication module to receive and parse StarSignal adapter protocol frames and restore them to standard USB transactions, so that the operating system of the computing device can recognize the standard peripheral as a local direct-connect device.

[0038] Furthermore, standard peripherals connect directly to the physical peripheral interface of the wireless display device. Peripherals are no longer connected to the host computer, but rather to the display device, thus achieving a cable-free desktop. The physical peripheral interface includes multiple USB Type-A ports, one USB Type-C port, a 3.5mm audio jack, or a touch-sensitive area for connecting standard peripherals compliant with USB, HID, or audio specifications.

[0039] Furthermore, standard peripherals include keyboards, USB flash drives, 4K webcams, and NVMe external hard drives. Standard peripherals comply with USB, Bluetooth HID, UVC, or audio interface specifications and do not require support for StarFlash communication.

[0040] Furthermore, computing devices include, but are not limited to, desktop computers, laptops, servers, or tablets.

[0041] Specifically, such as Figure 2 As shown, the StarShine Adaptation Protocol frame is the core data unit for transmitting peripheral data on the StarShine SLE link, and its core fields include:

[0042] USB Transaction Type Identifier: Located in the frame header, this identifier indicates the type of the current transaction, such as SETUP (control transfer), IN (host reads data from device), or OUT (host writes data to device). This identifier ensures that the basic semantics of USB communication are correctly maintained over the wireless link.

[0043] Local device address: A unique logical address assigned to each connected peripheral by the peripheral management unit of the wireless display device (such as a wireless monitor) during the local enumeration phase. This address is used to accurately address multiple peripherals on the wireless link. The peripheral management unit maintains a local USB address pool (address range 1–127); when a peripheral insertion event is detected, an enumeration process is initiated according to the USB 2.0 specification, including reset, obtaining descriptors, and assigning unique addresses; if multiple peripherals are connected simultaneously, a polling or interrupt priority mechanism is used to complete the enumeration sequentially to ensure address uniqueness.

[0044] The StarSpark Adaptation Protocol Frame Data Structure enables seamless mapping of standard USB transactions to the StarSpark wireless link, providing a protocol foundation for transparent relay of core peripheral data.

[0045] Endpoint number: Identifies a specific communication endpoint within a peripheral device (such as a control endpoint, interrupt endpoint, or bulk transfer endpoint), and together with the local device address, enables precise end-to-end data routing.

[0046] Payload: The main body of the protocol frame, carrying the actual data from the peripheral device (such as keyboard key press information, camera video data stream, or file data from a USB flash drive).

[0047] CRC checksum field (optional): Located at the end of the frame, it is used to perform cyclic redundancy check on the entire protocol frame to ensure the integrity of the data during StarScan wireless transmission. The receiver can use this checksum to verify the correctness of the data, thus providing a high level of reliability.

[0048] Furthermore, video signals between wireless display devices and computing devices are transmitted via independent wireless or wired links to separate them from standard peripheral data paths.

[0049] Furthermore, it also includes a wired backup mode: the wireless display device and the computing device are connected via a USB cable; when the StarFlash wireless link is interrupted or the signal quality deteriorates (such as packet loss rate > 5% or RSSI < -80dBm), the system automatically or manually switches to the wired connection via the USB cable, and transmits standard peripheral data to the computing device via the USB cable, and the USB cable does not carry video signals.

[0050] Specifically, the wired backup mode is an optional enhancement that depends on both devices having the corresponding interface and is not necessary to implement the basic functions of this invention.

[0051] The peripheral relay system for wireless display devices based on StarFlash Communication includes:

[0052] The wireless display device is equipped with a peripheral management unit and a first StarSpark SLE communication module. The peripheral management unit performs local USB enumeration on standard peripherals connected to the wireless display device, assigns local device addresses and endpoint numbers, and encapsulates the peripheral data stream into StarSpark adaptation protocol frames. The StarSpark adaptation protocol frames carry the USB transaction type and the local device address of the corresponding standard peripheral. The first StarSpark SLE communication module sends the StarSpark adaptation protocol frames to the target device (computing device) through the StarSpark wireless link.

[0053] The computing device has a built-in second StarShan SLE communication module and a virtual USB Host driver. The second StarShan SLE communication module is used to receive StarShan adaptation protocol frames through the StarShan wireless link; the virtual USB Host driver is used to parse the StarShan adaptation protocol and restore it to a standard USB transaction, so that the operating system can recognize the standard peripheral as a locally connected device.

[0054] The virtual USB Host driver can be implemented as follows: in Linux systems, it is registered as a kernel module as a USBgadget driver; in Windows systems, it is implemented as a virtual USB Host controller through WDF (Windows Driver Framework); in macOS, it is created using the IOKit framework to create a virtual USB device node. Its core function is to convert the received StarSpark adapter protocol frames into URB (USB Request Block) requests that can be recognized by the operating system's USB stack. The driver can be automatically loaded when the operating system starts.

[0055] Specifically, wireless display devices may include:

[0056] The display panel is used to receive and present video image signals from computing devices. The display panel can use LCD, OLED or Mini-LED technology, and its video input can be completed through independent wireless video transmission protocols (such as WiGig or StarFlash Video Channel) or wired interfaces (such as HDMI, DisplayPort).

[0057] Physical peripheral interfaces, including multiple USB Type-A ports, one USB Type-C port, a 3.5mm audio jack, or a touch-sensitive area, for connecting standard peripherals that conform to USB, HID, or audio specifications;

[0058] The peripheral management unit is used to perform local enumeration, protocol conversion, and data encapsulation of connected standard peripherals. The peripheral management unit maintains a local USB address pool (address range 1–127). When a peripheral insertion event is detected, an enumeration process of resetting, obtaining descriptors, and allocating unique addresses is initiated according to the USB 2.0 specification. If multiple peripherals are connected at the same time, the enumeration is completed sequentially using a polling or interrupt priority mechanism to ensure address uniqueness.

[0059] The first StarSignal SLE module is used to send the encapsulated peripheral data to the computing device via the StarSignal wireless link.

[0060] USB-C wired backup cable, used to establish a wired peripheral data path when the Starlink link is interrupted;

[0061] The NFC module enables secure and fast Starlink link establishment via a tap during initial pairing.

[0062] Specifically, the peripheral management unit encapsulates peripheral data into a StarSpark adapter protocol frame, which is then wirelessly transmitted to the computing device via the first StarSpark SLE module. The computing device receives the frame through its second StarSpark SLE module and restores it to a standard USB signal by the virtual USB driver, enabling the operating system to recognize the peripheral as a local device.

[0063] Furthermore, the computing device also has a built-in NFC chip, and the wireless display device is equipped with an NFC pairing module; upon first use, the NFC-enabled computing device will tap a designated area of ​​the display device to exchange security credentials and establish a StarFlash SLE encrypted link to complete the pairing.

[0064] In another embodiment, pairing can be completed by scanning a dynamic QR code displayed on the screen, or by entering a 6-digit pairing code to establish a StarFlash encrypted link.

[0065] Furthermore, the wireless display device is equipped with a USB-C interface, and the computing device is equipped with a corresponding USB-C or USB-A interface; the wireless display device is wired connected via a USB cable to form a wired path for relaying peripheral data in wired backup mode; the USB cable is used to transmit relay data of standard peripherals and does not carry video signals.

[0066] Specifically, when the signal quality of the StarSpark wireless link falls below a threshold (e.g., packet loss rate > 5% or RSSI < -80dBm), the system automatically switches the peripheral data stream from the first StarSpark SLE module to the USB-C wired backup cable. Connecting to the computing device via the USB-C wired backup cable is solely for peripheral data relay and does not carry video signals. This mode is an optional enhancement and depends on both devices having USB-C data interfaces.

[0067] Furthermore, the wireless display device is a combination of a StarSpark docking station without a display panel and a standard monitor, with the standard monitor connected to the StarSpark docking station via an HDMI / DP interface.

[0068] The present invention, employing the above technical solution, has the following beneficial effects: 1) By directly connecting peripherals to the display device and utilizing the StarFlash link for data relay, all physical cables used for peripheral connections between the host and the display device are completely eliminated, fundamentally solving the desktop clutter problem and achieving an extremely simple layout. 2) Based on StarFlash SLE communication, the end-to-end latency between the display device and the computing device can be less than 100 microseconds, far superior to technologies such as Bluetooth and USB over IP. It can seamlessly support all types of USB peripherals, from low-speed keyboards and mice to high-speed cameras and external hard drives, meeting the needs of high-performance scenarios such as e-sports and professional drawing.

Furthermore, the NFC touch pairing mechanism simplifies the initial setup process, greatly improving the user experience.

[0069] This invention connects standard peripherals directly to a wireless display device, which then wirelessly relays the data from these peripherals. This allows computing devices to achieve full-function interaction without the need for physical connections to peripherals, resulting in a streamlined desktop setup with no cables. It also provides an optional wired backup mechanism to ensure availability in extreme environments.
