[0002] In a conference room setting, a wireless display adapter connects to the meeting control system via a wireless network and proprietary protocols, transmitting the user's screen content to the meeting control system in real time. The meeting control system then connects the content to the display screen, enabling the sharing of the user's screen content.

[0003] Although wireless screen sharing devices can share screen content between user terminals via a wireless connection with the conference host, peripheral devices are connected by the conference host and wired to the conference table where the user terminal is located. Since the conference host is close to the display screen and far from the user terminal, the conference room setting still requires a lot of cable connections for audio acquisition, video input, and sound output of peripheral devices.

[0020] The wireless screen projection method of this application is applied to a wireless screen projection device, which is configured with a first communication interface, a second communication interface, and a first wireless network interface, and is also pre-installed with a network stream encapsulation tool and a protocol conversion tool.

Furthermore, this application installs a protocol conversion tool in the wireless projection device that matches the communication interface for connecting peripheral devices. This tool converts the second transmission object obtained by the communication interface of the peripheral device into a fourth transmission object conforming to the protocol of the wireless network interface. This allows the same wireless network interface to transmit the transmission objects of the user terminal and peripheral devices to the conference host. The conference host can then display the transmission object from the user terminal while simultaneously responding to the transmission object from the peripheral device. This enables the wireless projection device to not only support wireless projection but also act as an access node for peripheral devices, carrying their signal transmissions, thereby improving the functional expandability of the wireless projection device.

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] While wireless screen sharing devices can share content from user terminals via a wireless connection with the conference host, peripheral devices still require extensive cabling. This necessitates the conference host connecting the peripherals and then wiring them to the conference table where the user terminals are located. Since the conference host is close to the display screen and far from the user terminals, the conference room setup still requires numerous cables for audio acquisition, video input, and sound output from the peripherals. This results in complex cabling between the conference table and the display screen, making installation difficult and aesthetically unappealing. To address this, this application provides a wireless screen sharing method that allows the wireless screen sharing device connected to the user terminal to directly connect to the peripheral device, avoiding the need for the conference host to connect to the peripheral device and then wiring it to the conference table where the user terminals are located. This solves the problems of complex cabling, difficult installation, and aesthetic impact.

[0026] See Figure 1 As shown in the figure, this application discloses a wireless screen projection method applied to a wireless screen projection device. The wireless screen projection device is configured with a first communication interface, a second communication interface, and a first wireless network interface, and the wireless screen projection device is also pre-installed with a network stream encapsulation tool and a protocol conversion tool; the method includes: Step S11: Obtain the first transmission object of the user terminal through the first communication interface.

[0027] In this embodiment, the wireless screen mirroring device connects to the user terminal via a first communication interface to obtain the user terminal's first transmission object. The first communication interface can be a USB (Universal Serial Bus) interface, such as a Type-A interface or a Type-C interface. Furthermore, the user terminal includes, but is not limited to, smartphones, tablets, and computers; the user terminal's first transmission object is a transmission object determined based on the screen mirroring content of the user terminal.

[0028] According to one example, the wireless screen projector can obtain a first transmission object sent by the user terminal through the Type-C interface via the first communication interface, and the first transmission object conforms to the DisplayPort (DP, a digital display interface standard) standard.

[0029] Step S12: Obtain the second transmission object of the peripheral device through the second communication interface.

[0030] In this embodiment, the wireless screen projector connects to a peripheral device via a second communication interface to obtain a second transmission target from the peripheral device. The number of second communication interfaces can be one or more, and these interfaces include, but are not limited to, USB interfaces, audio interfaces, Thunderbolt interfaces, etc. USB interfaces include, but are not limited to, Type-A interfaces, Type-B interfaces, Type-C interfaces, etc.

[0031] Peripheral devices include, but are not limited to, microphones, speakers, cameras, and HID (Human Interface Device) devices, including but not limited to mice, keyboards, touchpads, and touchscreens. Correspondingly, the second transmission target of the peripheral devices is the transmission target determined based on the signals collected by the peripheral devices.

[0032] It should be noted that the wireless screen projector also includes a multi-device extender for connecting the second communication interface and at least one peripheral device. That is, the multi-device extender allows one second communication interface to connect to multiple peripheral devices simultaneously. Correspondingly, the wireless screen projector can obtain the second transmission object of at least one peripheral device sent by the multi-device extender through the second communication interface. In this way, the wireless screen projector of this application, through the multi-device extender, allows one second communication interface to connect to multiple peripheral devices simultaneously, thereby alleviating the problems of high cost and complex wiring associated with deploying multiple second communication interfaces in the wireless screen projector to connect multiple peripheral devices.

[0033] Step S13: The first transmission object is encapsulated into a network stream using the network stream encapsulation tool to obtain a third transmission object, and the third transmission object is transmitted to the conference host for display via the first wireless network interface.

[0034] In this embodiment, the wireless screen projector obtains the first transmission object transmitted through the first communication interface using a network stream encapsulation tool, encapsulates the first transmission object into a network stream to obtain a third transmission object, and then transmits the third transmission object to the first wireless network interface so that the third transmission object can be transmitted to the conference host through the first wireless network interface so that the conference host can perform display operations on the received third transmission object.

[0035] For network stream encapsulation tools, wireless screen projectors specifically use network stream encapsulation tools to first encode the first transmission object, and then encapsulate the encoded transmission object into a network stream to obtain the third transmission object.

[0036] According to one example, when the network stream encapsulation tool includes an encoder and an encapsulation component, the wireless projector encodes the first transmission object using the encoder to obtain an encoded transmission object, and then transmits the encoded transmission object to the encapsulation component. The encapsulation component then encapsulates the encoded transmission object into a network stream to obtain a third transmission object. It should be noted that the encoder includes, but is not limited to, 4K resolution encoders, 8K resolution encoders, etc.

[0037] Correspondingly, the wireless screen projector transmits the third transmission object to the conference host through the first wireless network interface, so that the conference host can decapsulate the third transmission object and decode the decapsulated transmission object in order to display the decoded transmission object.

[0038] The first wireless network interface can be a wireless bridge, specifically a 5GHz Wi-Fi bridge, a 2.4GHz Wi-Fi bridge, a 5.8GHz Wi-Fi bridge, etc.

[0039] Furthermore, the conference host includes a second wireless network interface and a controller. Correspondingly, the wireless projection device transmits the third transmission object to the conference host through the first wireless network interface, so that after receiving the third transmission object through the second wireless network interface, the conference host transmits the third transmission object to the controller and performs display operations on the third transmission object through the controller.

[0040] More specifically, after receiving the third transmission object through the second wireless network interface, the conference host transmits the third transmission object to the controller, and then the controller decapsulates the third transmission object, decodes the decapsulated transmission object, and displays the decoded transmission object.

[0041] The second wireless network interface in the conference host matches the first wireless network interface in the wireless screen projector. Furthermore, the controller in the conference host can use highly integrated chips such as SoC (System on Chip) and MCU (Microcontroller Unit), which can integrate multiple functional modules such as processor core, memory, and IO (Input / Output) interface onto a single chip.

[0042] In this embodiment, the display operation is the operation of the conference host transmitting the image to be displayed to the display medium for display; the image to be displayed is the image determined by the conference host based on the received transmission object. The display medium includes, but is not limited to, projectors, displays, etc., and the conference host is connected to the display medium via a multimedia interface, which includes, but is not limited to, HDMI (High Definition Multimedia Interface), USB interface, DP (DisplayPort) interface, etc.

[0043] Step S14: The second transmission object is converted using the protocol conversion tool, and the converted fourth transmission object is transmitted to the conference host through the first wireless network interface, so that the conference host can execute the target response operation corresponding to the fourth transmission object; wherein, the target response operation is a response operation determined based on the information type of the fourth transmission object.

[0044] In this embodiment, the wireless screen projector obtains the second transmission object transmitted through the second communication interface through a protocol conversion tool, performs protocol conversion on the second transmission object to obtain the fourth transmission object, and then transmits the fourth transmission object to the first wireless network interface. The fourth transmission object is then transmitted to the conference host through the first wireless network interface, so that the conference host can determine the target response operation based on the information type of the fourth transmission object and execute the target response operation corresponding to the fourth transmission object.

[0045] It should be noted that the protocol conversion tool is used to convert the transmission object between the interface protocol and the network protocol; the interface protocol is the protocol corresponding to the second communication interface, and the network protocol is the protocol corresponding to the first wireless network interface. That is, the protocol conversion tool can convert a transmission object of the interface protocol to a transmission object of the network protocol, and vice versa. Furthermore, when the second communication interface is a USB interface, the protocol conversion tool can use a hub.

[0046] Specifically, the conference host includes a second wireless network interface, a virtualization engine, and a controller. Correspondingly, the wireless projection device transmits the fourth transmission object to the conference host via the first wireless network interface. After receiving the fourth transmission object through the second wireless network interface, the conference host transmits it to the virtualization engine. The virtualization engine then maps the peripheral device's virtualization device locally based on the fourth transmission object. The controller then calls the virtualization device to retrieve the fourth transmission object and executes the corresponding target response operation. In this way, by mapping the peripheral device's virtualization device locally through the virtualization engine, the conference host can invoke the peripheral device as if it were connected locally.

[0047] For example, when the peripheral device is an omnidirectional microphone, not only can the wireless screen projector have the ability to directly connect to the omnidirectional microphone, avoiding reliance on the conference host in the voice acquisition stage, thereby expanding the audio acquisition function of the wireless screen projector, but also through the virtualization engine in the conference host, the microphone's acquisition function can be mapped to the conference host, so that the conference host can call up audio data as if the microphone were connected locally.

[0048] For example, when the peripheral device is a video input device such as a camera, it not only enables the wireless screen projector to directly connect to the video input device such as a camera, avoiding reliance on the conference host in the video acquisition stage, thereby expanding the video acquisition function of the wireless screen projector, but also allows the acquisition function of the video input device such as a camera to be mapped to the conference host through the virtualization engine in the conference host, so that the conference host can call up video data as if the video input device such as a camera is connected locally.

[0049] For example, when the peripheral device is an HID device, not only can the wireless projector have the ability to directly connect to the HID device, thereby expanding the human-computer interaction capabilities of the wireless projector, but the transmission object of the HID device is also wirelessly transmitted to the conference host so that the conference host can respond to the transmission object of the HID device. Users can remotely input and interactively control the conference host during the meeting by connecting the wireless projector to the HID device.

[0050] It should be noted that the wireless screen projector transmits the transmission object of at least one peripheral device to the conference host, so that the conference host can use the virtualization engine to map the virtual device of the peripheral device locally based on the transmission object of the peripheral device, thereby enabling the conference host to achieve centralized management and scheduling of the peripheral devices.

[0051] Furthermore, since the target response operation is determined based on the information type of the fourth transmitted object, different information types of transmitted objects correspond to different response operations. For example, when the peripheral device is an audio input device such as a microphone, and the information type of the fourth transmitted object is audio information, the target response operation can be an operation to play audio on the fourth transmitted object; when the peripheral device is a video input device such as a camera, and the information type of the fourth transmitted object is video / image information, the target response operation can be an operation to display the fourth transmitted object.

[0052] When the target response operation includes a display operation, after receiving the fourth transmission object transmitted by the wireless screen projector, the conference host performs the display operation corresponding to the fourth transmission object, that is, displays the fourth transmission object. It should be noted that when the conference host simultaneously displays the third transmission object of the user terminal, the conference host will composite the third transmission object of the user terminal and the fourth transmission object of the peripheral device to obtain the image to be displayed, and then transmit the image to be displayed to the display media for display.

[0053] In order to achieve two-way interaction between the user equipment and the conference host, the wireless screen projector of this application can obtain the fifth transmission object sent by the conference host through the first wireless network interface and transmit the fifth transmission object to the protocol conversion tool; wherein, the fifth transmission object is the media object currently displayed on the display media; the protocol conversion tool performs protocol conversion on the fifth transmission object and transmits the converted sixth transmission object to the user equipment for response; wherein, the user equipment includes a user terminal and / or peripheral devices.

[0054] In other words, the conference host determines the currently displayed media object through the controller to obtain the fifth transmission object, and sends the fifth transmission object to the second wireless network interface via the virtualization engine. Then, the fifth transmission object is transmitted to the wireless screen projector through the second wireless network interface. Correspondingly, the wireless screen projector obtains the fifth transmission object through the first wireless network interface, transmits the fifth transmission object to the protocol conversion tool, performs protocol conversion on the fifth transmission object through the protocol conversion tool, and transmits the converted sixth transmission object to the user equipment for response.

[0055] According to one example, when the user equipment is a user terminal, the user terminal responds to the sixth transmitted object through locally running conferencing software; for example, when the sixth transmitted object is video information, the user terminal plays the sixth transmitted object through locally running conferencing software.

[0056] According to one example, when the user device is a peripheral device, the peripheral device directly responds to the sixth transmitted object. For example, when the sixth transmitted object is audio information and the peripheral device is a speaker, the speaker directly plays the sixth transmitted object.

[0057] Therefore, this application, by configuring a communication interface for connecting peripheral devices in the wireless projection device, allows the wireless projection device connected to the user terminal to directly connect to peripheral devices. Since the wireless projection device is close to the user terminal and is generally located on the conference table where the user terminal is located, connecting the wireless projection device to the peripheral device and then wiring it to the conference table where the user terminal is located can greatly reduce cable connections. It can even simultaneously connect the user terminal and peripheral devices to the conference table where the user terminal is located, avoiding the need for the conference host to connect the peripheral devices and then wiring them to the conference table where the user terminal is located, thus solving the problems of complex wiring, difficult construction, and aesthetic impact. Furthermore, this application installs a protocol conversion tool in the wireless projection device that matches the communication interface for connecting peripheral devices. This tool converts the second transmission object obtained by the communication interface of the peripheral device into a fourth transmission object conforming to the protocol of the wireless network interface. This allows the same wireless network interface to transmit the transmission objects of the user terminal and peripheral devices to the conference host. The conference host can then display the transmission object from the user terminal while simultaneously responding to the transmission object from the peripheral device. This enables the wireless projection device to not only support wireless projection but also act as an access node for peripheral devices, carrying their signal transmissions, thereby improving the functional expandability of the wireless projection device.

[0058] See Figure 2 As shown in the figure, this application discloses a wireless screen projection method applied to a conference host, including: Step S21: Obtain the third transmission object transmitted by the wireless screen projector through the first wireless network interface, and perform a display operation on the third transmission object; the third transmission object is the transmission object obtained by the wireless screen projector by encapsulating the first transmission object into a network stream using a network stream encapsulation tool, and the first transmission object is the transmission object obtained by the wireless screen projector from the user terminal through the first communication interface.

[0059] In the embodiments of this application, such as Figure 3As shown, the wireless screen projector connects to the user terminal via a first communication interface to obtain a first transmission object from the user terminal. This first transmission object is then transmitted to a network stream encapsulation tool, which encapsulates it into a network stream to obtain a third transmission object. This third transmission object is then transmitted to a first wireless network interface, which in turn transmits it to the conference host. Correspondingly, the conference host obtains the third transmission object transmitted by the wireless screen projector via the first wireless network interface through a second wireless network interface. This third transmission object is then transmitted to the controller. The controller determines the screen to be displayed based on the third transmission object and transmits the screen to the display media via a multimedia interface for display.

[0060] Step S22: Obtain the fourth transmission object transmitted by the wireless screen projector through the first wireless network interface, and execute the target response operation corresponding to the fourth transmission object; the fourth transmission object is the transmission object obtained by the wireless screen projector after performing protocol conversion on the second transmission object through a protocol conversion tool, and the second transmission object is the transmission object obtained by the wireless screen projector from the peripheral device through the second communication interface; the target response operation is a response operation determined based on the information type of the fourth transmission object.

[0061] In the embodiments of this application, such as Figure 3 As shown, the wireless screen projector connects to peripheral devices via a second communication interface and a multi-device extender to obtain the second transmission object from the peripheral devices. This second transmission object is then transmitted to a protocol conversion tool, which performs protocol conversion on it to obtain a fourth transmission object. This fourth transmission object is then transmitted to a first wireless network interface, which in turn transmits it to the conference host. Correspondingly, the conference host obtains the fourth transmission object transmitted by the wireless screen projector via the first wireless network interface through the second wireless network interface. This fourth transmission object is then transmitted to the virtualization engine. The virtualization engine maps the peripheral devices locally based on the fourth transmission object and uses the controller to call the virtualization device to obtain the fourth transmission object. Finally, based on the information type of the fourth transmission object, the target response operation is determined and executed.

[0062] When the target response operation includes a display operation, after receiving the fourth transmission object transmitted by the wireless screen projector, the conference host executes the display operation corresponding to the fourth transmission object through the controller, that is, performs a display operation on the fourth transmission object. It should be noted that when the controller performs a display operation on the third transmission object of the user terminal at the same time, the controller will combine the third transmission object of the user terminal and the fourth transmission object of the peripheral device to obtain the image to be displayed, and then transmit the image to be displayed to the display media through the multimedia interface for display.

[0063] To enable bidirectional interaction between the user device and the conference host, the conference host determines the currently displayed media object through the controller to obtain the fifth transmission object. This fifth transmission object is then sent to the second wireless network interface via the virtualization engine, and subsequently transmitted to the wireless projection device through the second wireless network interface. Correspondingly, the wireless projection device obtains the fifth transmission object through the first wireless network interface and transmits it to a protocol conversion tool. The protocol conversion tool then performs protocol conversion on the fifth transmission object and transmits the resulting sixth transmission object to the user device for response.

[0064] Therefore, this application, by configuring a communication interface for connecting peripheral devices in the wireless projection device, allows the wireless projection device connected to the user terminal to directly connect to peripheral devices. Since the wireless projection device is close to the user terminal and is generally located on the conference table where the user terminal is located, connecting the wireless projection device to the peripheral device and then wiring it to the conference table where the user terminal is located can greatly reduce cable connections. It can even simultaneously connect the user terminal and peripheral devices to the conference table where the user terminal is located, avoiding the need for the conference host to connect the peripheral devices and then wiring them to the conference table where the user terminal is located, thus solving the problems of complex wiring, difficult construction, and aesthetic impact. Furthermore, this application installs a protocol conversion tool in the wireless projection device that matches the communication interface for connecting peripheral devices. This tool converts the second transmission object obtained by the communication interface of the peripheral device into a fourth transmission object conforming to the protocol of the wireless network interface. This allows the same wireless network interface to transmit the transmission objects of the user terminal and peripheral devices to the conference host. The conference host can then display the transmission object from the user terminal while simultaneously responding to the transmission object from the peripheral device. This enables the wireless projection device to not only support wireless projection but also act as an access node for peripheral devices, carrying their signal transmissions, thereby improving the functional expandability of the wireless projection device.
