[0023] The content of the present invention will be described below with multiple embodiments. Please also note that the "first", "second" and similar descriptions in the following descriptions are only used to define different elements, parameters, data, signals or steps, and are not used to limit their order. For example, the first device and the second device may be devices with the same structure but different.
[0024] Figure 1 is a schematic diagram showing a wireless connection method according to an embodiment of the present invention. As Figure 1As shown, a wireless communication system including a first host device HO_1 and a first adapter (dongle) DO_11 is provided. The first adapter DO_11 is a device that can store at least one program (such as an application program) and can automatically execute the program. For example, the first adapter DO_11 detects whether it is inserted (i.e., connected to) the first device DE_11, and if the first adapter DO_11 is inserted into the first device DE_11, the first adapter DO_11 broadcasts reconnection information to connect the first adapter DO_11 and the first host device HO_1 (where the first adapter DO_11 and the first host device HO_1 are pre-paired). Conversely, if the first adapter DO_11 is not inserted into the first device DE_11, the first adapter DO_11 does not broadcast reconnection information.
[0025] Also note that the action of "inserting the first adapter DO_11 into the first device DE_11" here refers to inserting the first adapter DO_11 into any electronic device, without restricting the electronic device to be a specific first device DE_11. In an embodiment, if the physical connection port of the first adapter DO_11 is inserted into a device that follows a predetermined standard or has a specific structure, the first adapter DO_11 broadcasts reconnection information. For example, if the first adapter DO_11 includes a USB port, when the USB port of the first adapter DO_11 is inserted into another USB port, the first adapter DO_11 broadcasts reconnection information. In an embodiment, the first device DE_11 is a notebook computer, but is not limited thereto. The first device DE_11 can be any other electronic device, such as a tablet computer or a mobile phone.
[0026] Then, the first device DE_11 connects to the first host device HO_1 according to the reconnection information to establish a first wireless connection between the first device DE_11 and the first host device HO_1. In an embodiment, the first host device HO_1 also includes an authentication mechanism to confirm whether the first device DE_11 is a permitted device that should provide connection information. For example, the user of the first device DE_11 needs to provide a password after connecting to the first host device HO_1, otherwise, even if the first device DE_11 has been connected to the first host device HO_1, it cannot obtain connection information. This connection information is used for a second wireless connection, and its details will be described in subsequent embodiments. In this way, malicious connections to the first host device HO_1 or the second wireless connection can be blocked.
[0027] In addition, in one embodiment, the first host device HO_1 records the identification information of the adapter, such as the Bluetooth ID, and deletes the identification information of the adapter that is not suitable for receiving connection information or connecting to the first host device HO_1. For example, the first host device HO_1 records the Bluetooth ID of the first adapter DO_11 and sets this Bluetooth ID in the allow list. If the Bluetooth ID of the first adapter DO_11 is in the allow list, the first adapter DO_11 is allowed to connect to the first host device HO_1 and / or receive connection information. If the first adapter DO_11 is lost, the user can delete the Bluetooth ID of the first adapter DO_11 from the allow list, so that the first adapter DO_11 cannot connect to the first host device HO_1 and / or receive connection information. In this way, even if the lost first adapter DO_11 is found by someone who has no right to use the first host device HO_1 or the second wireless connection, he cannot use the first host device HO_1 through the first adapter DO_11. Therefore, the security of the wireless communication system can be ensured.
[0028] The first wireless connection can be any wireless connection, such as a proprietary radiofrequency connection or a Bluetooth connection. In one embodiment, the first wireless connection is established by the first adapter DO_11 and the first wireless communication device 103 located in the first host device HO_1. For example, if the first wireless connection is a Bluetooth connection, the first wireless communication device 103 is a Bluetooth device, and the first adapter DO_11 also provides Bluetooth functionality. In another embodiment, the wireless communication system further includes a second adapter DO_2 inserted into the first host device HO_1. In this case, the first adapter DO_11 serves as the slave communication device of the first wireless connection, and the second adapter DO_2 connected to the first host device HO_1 serves as the master device of the first wireless connection. For example, the first wireless connection can use a proprietary radiofrequency protocol. Or, if the first wireless connection is a Bluetooth connection, the second adapter DO_2 serves as a BLE central device, and the first adapter DO_11 serves as a BLE peripheral device. In one embodiment, the type of the wireless connection can be automatically selected according to the type of the first device DE_11. For example, if the first device DE_11 is a mobile phone, a Bluetooth connection is used; if the first device DE_11 is a laptop computer, a proprietary radiofrequency connection is used.
[0029] In one embodiment, the first adapter DO_11 has been pre-paired with the second adapter DO_2. For example, the first adapter DO_11 has been paired with the second adapter DO_2 at the manufacturing factory or by the customer who purchased it. In this case, if the first adapter DO_11 is inserted into the first device DE_11, the first adapter DO_11 broadcasts reconnection information to connect the first adapter DO_11 and the second adapter DO_2.
[0030] After the first wireless connection is established, the first adapter DO_11 automatically receives the connection information of the above-mentioned second wireless connection from the first host device HO_1 through the first wireless connection, and automatically provides the connection information to the first device DE_11. The second wireless connection can be a wireless connection provided by the first host device HO_1. For example, the wireless connection provided by the first host device HO_1 is Wi-Fi. In such a scenario, the first host device HO_1 can be a simulated router of Wi-Fi. In addition, the second wireless connection can be a wireless connection independent of the first host device HO_1. For example, the first host device HO_1 is a computer in a meeting room, and the second wireless connection is Wi-Fi 101 provided by an AP (wireless access point) in the meeting room.
[0031] After the first device DE_11 receives the connection information, the first device DE_11 connects to the second wireless connection through the connection information. The connection information can be the information required to use the second wireless connection, such as an account number, password, IP address, communication protocol type, etc. Taking the second wireless connection as Wi-Fi as an example, the connection information can be a Wi-Fi profile. After the first device DE_11 connects to the second wireless connection, the screen of the first device DE_11 can be mirrored to the second device by the first host device HO_1 through the second wireless connection. Note that the "mirror screen" step can mean mirroring the live content being played on the first device or the content selected by the user. For example, if the first device is playing a video and the "mirror screen" step is triggered, the second device that receives the mirrored screen will also play the video. Another example is that if the "mirror screen" step is triggered, the user of the first device can select a file stored in the first device and mirror the file to the second device.
[0032] The second device can be various electronic devices and the number thereof is not limited to 1. For example, in Figure 1In an embodiment, the second devices DE_21, DE_22, and DE_23 are a display, a laptop computer, and a mobile phone, respectively. The second devices DE_21, DE_22, and DE_23 can be located at the same location. For example, they are in the same meeting room as the first device DE_11 and the first host device HO_1. In this case, the second devices DE_21, DE_22, and DE_23 can be connected to the first host device HO_1 through a wired connection or a wireless connection. However, the second devices DE_21, DE_22, and DE_23 can be located in at least two different buildings, cities, or countries. For example, the second devices DE_21 and DE_22 are in the United States, and the second device DE_23 is in Europe. In this case, the second devices DE_21, DE_22, and DE_23 can be connected to the first host device HO_1 through a wireless connection (such as the World Wide Web).
[0033] Also understand that the number of the first devices can be more than one. For example, Figure 1 Another first device DE_12 is also provided. In this case, each of the first devices DE_11 and DE_12 can mirror its screen to at least one second device according to the above steps. However, one of the first devices can also mirror its screen to another one of the first devices. For example, in Figure 1 the embodiment, the screen of the first device DE_11 can be mirrored to the first device DE_12. This step can also be regarded as mirroring the screen of the first device to a third electronic device different from the first device and the second electronic device.
[0034] The above steps can be executed by executing the application program in the first adapter DO_11 or by executing the application program installed in the first device DE_11. In an embodiment, when the first adapter DO_11 is inserted into the first device DE_11, the first adapter DO_11 can automatically execute the application program stored therein or install the application program into the first device DE_11, so that the first device DE_11 can execute Figure 1 the steps related to the first device DE_11 in Figure 1 . In another embodiment, the user of the first device DE_11 can manually execute the application program stored in the first adapter DO_1 or manually install the application program into the first device DE_11, so that the first device DE_11 can execute
[0035] In addition to Figure 1 the mechanisms shown, the present invention also discloses other mechanisms. Figure 2A FIG. is a schematic diagram showing a wireless connection method according to another embodiment of the present invention. Also note that for the convenience of description, Figure 1Some of the components shown are not shown in Figure 2A . As shown in Figure 2A , in addition to the first devices DE_11, DE_12, the first adapters DO_11, DO_12, and the second adapter DO_2 shown in Figure 1 , the wireless communication system further includes a first device DE_13, a first adapter DO_13, an adapter DO_a, and a first device DE_1a. In one embodiment, the adapter DO_a and the second adapter DO_2 can be combined into a single adapter.
[0036] In the embodiment of Figure 2A , the adapter DO_a detects whether it is inserted into the first host device HO_1. For example, the adapter DO_a detects whether it is inserted into any electronic device. If the adapter DO_a is inserted into the first host device HO_1, the adapter DO_a automatically broadcasts the connection information of the second wireless connection. The first device DE_1a automatically receives the connection information without establishing a first wireless connection between the first host device HO_1 and the first device DE_1a, and without establishing a first wireless connection between the adapter DO_a and the first device DE_1a. In the embodiment of Figure 2A , the first device DE_1a is a mobile phone, but it can also be other electronic devices, such as a tablet computer or a notebook computer. If the first device DE_1a is a mobile phone or a tablet computer, the first device DE_1a can scan a QR code to install an application program so that the first device DE_1a can execute the steps related to the first device DE_1a in Figure 2A .
[0037] The second wireless connection can be a wireless connection provided by the first host device HO_1, such as Wi-Fi provided by the first host device HO_1. In addition, the second wireless connection can be a wireless connection independent of the first host device HO_1. For example, the first host device HO_1 is a computer in a meeting room, and the second wireless connection is the Wi-Fi 101 in Figure 1 , which is provided by an AP (Wireless Access Point) in the meeting room. Then, the first host device HO_1 mirrors the screen of the first device DE_11 to the second device through the second wireless connection. In the example where the second wireless connection is Wi-Fi, the connection information can be a Wi-Fi profile.
[0038] After the first device DE_1a receives the connection information, the first device DE_1a can mirror its screen to the second device through the second wireless connection. The details of the second device have been described in the above Figure 1 and will not be elaborated here.
[0039] In Figure 1In an embodiment, the operation of the first device can be controlled by the first host device HO_1 or the first device itself. For example, after the first device DE_11 is connected to the first host device HO_1 through a second wireless connection, the "screen mirroring" of the first device DE_11 can be controlled by the first host device HO_1. For example, the user can use a mouse that has been connected to the first host device HO_1 through a wired connection or a wireless connection to control the first device DE_11 through the first host device HO_1. Also for example, after the first device DE_11 is connected to the first host device HO_1 through a second wireless connection, the user can use a mouse that has been connected to the first device DE_11 through a wired connection or a wireless connection to control the first device DE_11. However, the operation of one first device can be controlled by another first device, such as Figure 2A the embodiment shown. In the following embodiments, the first device DE_12 or the first device DE_13 can be controlled by the first device DE_11.
[0040] In Figure 2A an embodiment, the first adapter DO_11 includes a management application. The management application can be an application independent of the above mirroring step or can be incorporated into the above application. In this case, the above connection information is provided to a third device (e.g., Figure 2A the first device DE_12 or the first device DE_13 in
[0041] ), so that the third device is connected to the first host device HO_1 through the second wireless connection and the foregoing steps. In addition, the first device DE_11 is set as a management device through the management application. Then, the operation of the third device can be controlled by the first device DE_11. In this case, the first device DE_11 can also control the first host device HO_1.
[0042] This mechanism can be regarded as two-way control. More specifically, data can be classified into information and HID stream. The HID stream is a data stream that complies with the (Human Interface Device) specification and may include commands. The host device can provide the HID stream to the client device, but the client device only provides information to the control device. Existing devices usually only use single-direction control. For example, an existing mouse can output commands to a corresponding adapter, but the corresponding adapter cannot output commands to the mouse. Another example is that an existing mouse can output commands to multiple corresponding adapters, but the corresponding multiple adapters cannot output commands to the mouse. Another example is that multiple keyboards and mice share the same adapter. The keyboards and mice can send commands to the adapter, but the adapter cannot send commands to the keyboards and mice. However, in the present invention, each of the first host device HO_1 and the first devices DE_11, DE_12, and DE_13 can act as a control device to control other devices. Therefore, the transmission of information and HID stream can be two-way, as Figure 2A shown.
[0043] Such a mechanism can be used in different applications. For example, if two-way control is applied to a KVM (keyboard, video, mouse) switching system, the first host device HO_1 can send information and HID stream to the first device to be controlled. In this case, the first host device HO_1 only transmits information to the first devices not controlled by the first host device HO_1. For example, the first host device HO_1 is used to control the first device DE_12, so it transmits information and HID stream to the first device DE_12, but only transmits information to the first devices DE_11 and DE_13. Similarly, if the first host device HO_1 switches to control the first device DE_13, the first host device HO_1 will transmit information and HID stream to the first device DE_13, but only transmit information to the first devices DE_11 and DE_12. In addition, in Figure 2A the embodiment, the first devices DE_12 and DE_13 not controlled by the first host device HO_1 only transmit information but do not transmit HID stream to the first host device HO_1.
[0044] Another example is that if two-way control is applied to a meeting room, the first device DE_12 can act as a control device to control the first host device HO_1. In this case, the first device DE_12 transmits information and HID stream to the first host device HO_1, but the first devices DE_11 and DE_13 only transmit information to the first host device HO_1.
[0045] To prevent data loss in two-way control, a data flow control mechanism is also disclosed in an embodiment. Figure 2B and Figure 2C To illustrate Figure 2A a schematic diagram of the data flow control mechanism for two-way control in Figure 2B and Figure 2C Although the embodiments in Figure 2B and Figure 2C are described with the first host device HO_1 and the first devices DE_11, DE_12, and DE_13, if the first devices DE_11, DE_12, and DE_13 are connected to the first host device HO_1 through an adapter,
[0046] In Figure 2B the embodiment of
[0047] In Figure 2C the embodiment of
[0048] In addition to mirroring the selected or displayed screen on the first device to the second electronic device, the first device can also serve as a virtual camera of the first control device. Figure 3 To illustrate a schematic diagram of a wireless connection method according to another embodiment of the present invention. As Figure 3 shown, in addition to Figure 1 the first device DE_11, the first adapter DO_11, and the first host device HO_1 shown in
[0049] In Figure 3In an embodiment, the first device DE_11 can execute a conferencing program, such that the first device DE_11, DE_1a, and DE_1b can join a conference generated by the conferencing program. In this case, if the first device DE_11 has the authority to control the conference, the virtual camera function of the conference can be triggered by the first device DE_11. In this case, the first device DE_11 can select at least one of the first devices DE_1a and DE_1b as the virtual camera content source, and the first device acting as the virtual camera can mirror its screen or the image sensed by its camera to the second device. For example, if the first device DE_1a is selected as the virtual camera and is displaying a document (Case 1), then the document is mirrored to the second device DE_21. This step is the same as the above mirroring step. Also, for example, if the first device DE_1b is selected as the virtual camera and is using the camera (Case 2), then the first device DE_1b will respond to the trigger and instantaneously mirror the image captured by its camera to the second device DE_22.
[0050] Please also note that the first device that selects the virtual camera and the first device acting as the virtual camera can be the same. For example, the first device DE_11 can select itself as the virtual camera. Additionally, the virtual camera function is not limited to being provided by the conferencing program. The virtual camera function can be provided by an application program executed by the first device or an application program installed on the first device. Additionally, the virtual camera function can be provided by the above management application program.
[0051] According to the above Figure 1 embodiment, a wireless connection method can be obtained, which includes steps as Figure 4 shown:
[0052] Step 401
[0053] Use a first adapter (e.g., the first adapter DO_11 in Figure 1 ) to detect whether the first adapter is inserted into the first device (e.g., the first device DE_11 in Figure 1 ).
[0054] In one embodiment, if the first adapter is inserted into the first device, the first adapter broadcasts pairing information.
[0055] Step 403
[0056] Connect the first adapter to the first host device to establish a first wireless connection (e.g., Bluetooth or RF) between the first device and the first host device.
[0057] Step 405
[0058] The first adapter automatically receives connection information of a second wireless connection (e.g., WiFi) from the first host device via the first wireless connection, and provides the connection information to the first device using the first adapter.
[0059] According to the above Figure 2A embodiment, a wireless connection method can be obtained, which includes the steps as Figure 5 shown:
[0060] Step 501
[0061] Use an adapter (e.g., the adapter DO_a in Figure 2A ) to detect whether the adapter is inserted into the first host device (e.g., the first host device HO_1 in Figure 2A ).
[0062] Step 503
[0063] If the adapter is inserted into the first host device, use the adapter to automatically broadcast the connection information of the second wireless connection.
[0064] Step 505
[0065] In the case where a first wireless connection between the first device (e.g., the first device DE_1a in Figure 2A ) and the first host device is not established, cause the first device to automatically receive the connection information.
[0066] Figure 4 And Figure 5 Other detailed steps of the wireless connection method shown in and have been disclosed in the above embodiments, so they will not be elaborated here. In addition, in the above embodiments, the wireless communication system and the wireless connection method are used for mirroring the screen. However, the wireless communication system and the wireless connection method disclosed in the present invention can also be used for other applications.
[0067] According to the above embodiments, the screen mirroring steps can be simplified, and only an adapter with a simple architecture is required, which can reduce the hardware cost.
[0068] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
