Transmission device used in video conferencing systems

Abstract

This invention discloses a transmitting end device for a video conferencing system. The video conferencing system also includes a receiving end device. The receiving end device wirelessly receives image signals transmitted from the transmitting end device and displays the image signals on a display coupled to the receiving end device. The transmitting end device includes memory storing identity information, which corresponds to the permissions of the transmitting end device. When the transmitting end device is coupled to an information processing device, the transmitting end device transmits the identity information to the information processing device. The application driver of the information processing device determines the permissions of the transmitting end device based on the identity information.

Description

Technical Field

[0001] This invention relates to video conferencing systems, and more particularly to a transmitting device used in video conferencing systems. Background Technology

[0002] In recent years, thanks to the rapid development of the Internet and video processing, multiple users in different locations can simultaneously connect via video using electronic devices such as computers, smartphones, and tablets. This allows users to see the dynamic images of other users on their screens while making voice calls, enhancing the realism and immersive experience of the communication. Therefore, video conferencing, which transmits both video and audio, has gradually replaced conference calls, which only transmit audio, as a common and efficient communication method.

[0003] Generally speaking, in a video conferencing context, users with different roles usually have different permissions and operating interfaces. For example, teachers or speakers usually have higher permissions and more functional operating interfaces, while students or listeners only need lower permissions and less functional operating interfaces.

[0004] However, current video conferencing systems still require users to go through complex pre-setup procedures according to their different identities before they can start a video conference smoothly. This makes it difficult for users of different ages and industries to get used to the operation and start using the system easily.

[0005] For example, since a school floor typically has multiple classrooms or meeting rooms, when a teacher enters a classroom to use a laptop application for screen sharing, in addition to undergoing complex pre-configuration procedures based on their teacher status, the application displays a long list of connectable receiver devices (RX). Even the teacher in charge of instruction may struggle to immediately select the correct receiver from the list, and might even mistakenly connect to a receiver in another classroom or meeting room, let alone students lacking operational experience. Furthermore, because traditional video conferencing systems are not compatible with all operating system platforms, different participants using different operating systems or hardware platforms still require support from the IT department to conduct video conferences smoothly, which is quite inconvenient.

[0006] As can be seen from the above, the problems encountered in the prior art still need to be further resolved. Summary of the Invention

[0007] One aspect of this invention is to disclose a transmitting device for a video conferencing system. This device can automatically identify the unique identity of each user's transmitting device (TX) and automatically provide the corresponding application interface, as well as automatically connect the transmitting device to the correct receiving device (RX). This significantly simplifies the previously complex pre-configuration process, enabling "plug and play" functionality when different users' transmitting devices are coupled to the information processing device. Furthermore, the receiving device (RX) with control command and position vector functions is compatible with different operating system platforms used by different participants (e.g., Android, iOS, Windows, Mac, etc.), thus effectively solving the aforementioned problems encountered in previous technologies.

[0008] According to a preferred embodiment of the present invention, a first transmitting end device is applied to a video conferencing system. In this embodiment, the video conferencing system further includes a receiving end device. The receiving end device wirelessly receives a first image signal transmitted from the first transmitting end device and displays the first image signal on a display coupled to the receiving end device. The first transmitting end device includes a first memory that stores first identity information, and the first identity information corresponds to a first permission of the first transmitting end device. When the first transmitting end device is coupled to a first information processing device, the first transmitting end device transmits the first identity information to the first information processing device. The first application driver of the first information processing device determines the first permission of the first transmitting end device based on the first identity information.

[0009] In one embodiment, the first application driver may further provide a first application interface to the first transmitting device according to the first permission, or the first application driver may launch the first application interface originally stored in the first information processing device according to the first permission, or the first application driver may download the first application interface to the first information processing device and launch the first application interface according to the first permission.

[0010] In one embodiment, the first application interface of the first information processing device sends control signals to control the functions of the second transmission device.

[0011] In one embodiment, the second transmitting device has a physical button, which is used to notify the receiving device to output the second image signal from the second information processing device to the display, and the control signal is used to disable the physical button.

[0012] In one embodiment, the second transmitting device includes a second memory for storing second identity information, and the second identity information corresponds to a second permission of the second transmitting device.

[0013] In one embodiment, the control signal is transmitted from the first information processing device to the second transmission device via the first transmission end device or directly from the first information processing device to the second transmission end device to disable at least one function of the second transmission end device.

[0014] In one embodiment, both the first transmitting end device and the second transmitting end device are connected to the receiving end device. The control signal is transmitted from the first information processing device to the receiving end device via the first transmitting end device or directly from the first information processing device to the receiving end device, causing the receiving end device to receive the second image signal provided by the second transmitting end device but not to provide it to the display for display. Alternatively, the control signal is transmitted from the first information processing device to the second transmitting end device in sequence via the first transmitting end device and the receiving end device to disable at least one function of the second transmitting end device.

[0015] In one embodiment, the first information processing device and the second transmission device are both located in the same network domain. The first information processing device transmits control signals to the second transmission device through the network domain to disable at least one function of the second transmission device.

[0016] In one embodiment, when the second transmitting device is coupled to the second information processing device, the second transmitting device transmits second identity information to the second information processing device, and the second application driver of the second information processing device determines the second permission of the second transmitting device based on the second identity information.

[0017] In one embodiment, the second application driver of the second information processing device may also provide a second application interface to the second transmission device according to the second permission, or the second application driver may launch the second application interface originally stored in the second information processing device according to the second permission, or the second application driver may download the second application interface to the second information processing device and launch the second application interface according to the second permission.

[0018] In one embodiment, a first application interface of a first information processing device sends a control signal to disable at least one function of a second application interface of a second information processing device.

[0019] In one embodiment, the first application driver of the first information processing device compares the first transmission device corresponding to the first identity information and its first permissions from a list of transmission devices stored therein.

[0020] In one embodiment, the first application driver of the first information processing device determines the first permission corresponding to the first transmission device based on the role information provided by the first transmission device.

[0021] In one embodiment, the first authority level of the first transmitting device is higher than the second authority level of the second transmitting device.

[0022] In one embodiment, the first application interface has more functions than the second application interface.

[0023] In one embodiment, the operation request issued by the second application interface can only be performed after the first application interface has agreed to it.

[0024] In one embodiment, the first application interface controls the screen projection mode of the display via the receiving device and specifies that the display shows one or more screen projection windows in the screen projection mode.

[0025] In one embodiment, when the second application interface sends a screen mirroring request to the receiving device, the receiving device needs to obtain the consent of the first application interface before transmitting the screen mirroring screen of the second application interface to the display for display according to the screen mirroring request.

[0026] In one embodiment, the receiving device has control command and location vector functions, so that different operating system platforms can directly control related operations through a website or application within the same network domain.

[0027] Compared with existing technologies, this invention can not only automatically identify the unique identity of different users' transmitting devices (TX) and automatically provide a dedicated application interface with corresponding permissions in video conferencing scenarios, but also enable the transmitting device to automatically connect to the correct receiving device (RX). This greatly simplifies the originally complicated video conferencing pre-setup process, allowing different users' transmitting devices to achieve a "plug and play" effect when coupled to the information processing device. In addition, the receiving device (RX) with control command and position vector functions can be compatible with different operating system platforms (such as Android, iOS, Windows, Mac, etc.) used by different participants, thus effectively improving the convenience and satisfaction of users when operating in video conferencing scenarios.

[0047] To provide a better understanding of the purpose, structure, features and functions of the present invention, detailed descriptions are provided below with reference to specific embodiments.

[0048] According to a preferred embodiment of the present invention, a transmitting end device is used in a video conferencing system. In practical applications, this transmitting end device can be applied to various types of video conferencing scenarios, but is not limited thereto.

[0049] Please refer to Figure 1 , Figure 1 A schematic diagram illustrating the application of the transmitting end device in this embodiment to a video conferencing system is shown. Figure 1 As shown, the video conferencing system 1 includes a transmitting device TX and a receiving device RX. The transmitting device TX includes memory M, which stores identity information CF, and the identity information CF corresponds to the permissions AU of the transmitting device TX. When the transmitting device TX is coupled to the information processing device NB, the transmitting device TX transmits the identity information CF to the information processing device NB. When the information processing device NB receives the identity information CF from the transmitting device TX, the application driver AD of the information processing device NB automatically determines the permissions AU of the transmitting device TX based on the identity information CF.

[0050] In this embodiment, the transmitting device TX automatically connects to the corresponding receiving device RX (e.g., via WiFi in a classroom or office, but not limited to this) and wirelessly transmits the image signal IM to the receiving device RX. The receiving device RX is coupled to the display DIS. When the receiving device RX wirelessly receives the image signal IM from the transmitting device TX, the receiving device RX transmits the image signal IM to the display DIS for display.

[0051] In practical applications, the information processing device (NB) can be a notebook computer, desktop computer, tablet computer, or other device with information processing capabilities, but is not limited thereto. The display (DIS) can be a projector, television, touch screen, or other device with display capabilities, but is not limited thereto.

[0052] It should be noted that the application driver AD installed on the information processing device NB can compare the corresponding transmission device TX and its permissions AU from the list of transmission devices (TX) stored in the information processing device NB, or the application driver AD installed on the information processing device NB can determine the level of the permissions AU of the user corresponding to the transmission device TX based on the role information (such as teacher or student, supervisor or subordinate, speaker or listener, etc.) in the identity information CF provided by the transmission device TX, and perform subsequent actions according to its permissions AU, but it is not limited to this.

[0053] In another embodiment, the video conferencing system may also include multiple transmitting devices, each corresponding to a different user identity and permissions. In practical applications, these multiple transmitting devices can be used in various types of video conferencing scenarios, but are not limited thereto.

[0054] like Figure 2As shown, the video conferencing system 2 includes a first transmitting device TX1, a second transmitting device TX2, and a first receiving device RX1. The first receiving device RX1 can be coupled to a display DIS. The first receiving device RX1 can also be wirelessly connected to the first transmitting device TX1, the second transmitting device TX2, and the second receiving device RX2. The first transmitting device TX1 can be coupled to a first information processing device NB1. The first transmitting device TX1 can also be wirelessly connected to the first receiving device RX1 and the second transmitting device TX2. The second transmitting device TX2 can be coupled to a second information processing device NB2. The second transmitting device TX2 can also be wirelessly connected to the first receiving device RX1, the first transmitting device TX1, and the first information processing device NB1.

[0055] like Figure 3A As shown, the first transmitting device TX1 includes a first memory M1, which stores first identity information CF1, and the first identity information CF1 corresponds to the first permission AU1 of the first transmitting device TX1. When the first transmitting device TX1 is coupled to the first information processing device NB1, the first transmitting device TX1 transmits the first identity information CF1 to the first information processing device NB1. When the first information processing device NB1 receives the first identity information CF1 from the first transmitting device TX1, the first application driver AD1 of the first information processing device NB1 automatically determines the first permission AU1 of the first transmitting device TX1 based on the first identity information CF1, and provides the first application interface APP1 to the first transmitting device TX1 accordingly based on the first permission AU1.

[0056] In practical applications, the first application driver AD1 may launch the first application interface APP1 that was originally stored in the first information processing device NB1 according to the first permission AU1, or the first application driver AD1 may download the first application interface APP1 to the first information processing device NB1 according to the first permission AU1 and launch the first application interface APP1 after the download is completed, but it is not limited to this.

[0057] Similarly, such as Figure 3BAs shown, the second transmitting device TX2 includes a second memory M2, which stores second identity information CF2, and the second identity information CF2 corresponds to the second permission AU2 of the second transmitting device TX2. When the second transmitting device TX2 is coupled to the second information processing device NB2, the second transmitting device TX2 transmits the second identity information CF2 to the second information processing device NB2. When the second information processing device NB2 receives the second identity information CF2 from the second transmitting device TX2, the second application driver AD2 of the second information processing device NB2 automatically determines the second permission AU2 of the second transmitting device TX2 based on the second identity information CF2, and provides the second application interface APP2 to the second transmitting device TX2 accordingly based on the second permission AU2.

[0058] In practical applications, the second application driver AD2 can launch the second application interface APP2 that was originally stored in the second information processing device NB2 according to the second permission AU2, or the second application driver AD2 can download the second application interface APP2 to the second information processing device NB2 according to the second permission AU2 and launch the second application interface APP2 after the download is completed, but it is not limited to this.

[0059] It should be noted that the first application interface APP1 corresponding to the first permission AU1 and the second application interface APP2 corresponding to the second permission AU2 can actually be two different applications or two different operation interfaces within the same application, without any specific restrictions.

[0060] In one embodiment, assuming that the level of the first permission AU1 (e.g., teacher permission) of the first transmitting device TX1 is higher than the level of the second permission AU2 (e.g., student permission) of the second transmitting device TX2, the first application interface APP1 of the first information processing device NB1 can send a control signal CTL to control the function of the second transmitting device TX2, but is not limited thereto.

[0061] For example, such as Figure 4A As shown, the control signal CTL issued by the first application interface APP1 of the first information processing device NB1 can be transmitted to the second transmission device TX2 via the first transmission device TX1 to disable at least one function of the second transmission device TX2, but is not limited thereto.

[0062] like Figure 4BAs shown, if the first information processing device NB1 and the second transmission terminal device TX2 are both in the same network domain, the control signal CTL issued by the first application interface APP1 of the first information processing device NB1 can be directly transmitted to the second transmission terminal device TX2 through the network domain to disable at least one function of the second transmission terminal device TX2, but not limited thereto.

[0063] like Figure 4C As shown, the control signal CTL issued by the first application interface APP1 of the first information processing device NB1 can be transmitted sequentially to the second transmission device TX2 via the first transmission device TX1 and the first receiving device RX1 to disable at least one function of the second transmission device TX2, but is not limited thereto.

[0064] like Figure 4D As shown, the control signal CTL issued by the first application interface APP1 of the first information processing device NB1 can be transmitted to the first receiving device RX1 via the first transmitting device TX1, so that although the first receiving device RX1 receives the second image signal IM2 provided by the second transmitting device TX2, it will not provide it to the display DIS for display, but this is not the limitation.

[0065] like Figure 4E As shown, the control signal CTL sent by the first application interface APP1 of the first information processing device NB1 can be directly transmitted to the first receiving device RX1, so that although the first receiving device RX1 receives the second image signal IM2 provided by the second transmitting device TX2, the first receiving device RX1 will not provide it to the display DIS for display, but this is not the limitation.

[0066] Please refer to Figure 4F and Figure 4G , Figure 4F A schematic diagram illustrating the appearance of a second transmission end device with a connection line supporting Universal Sequence Bus and high-resolution multimedia interface; Figure 4G A schematic diagram illustrating the appearance of a second transmitter device with a connection line supporting Universal Sequence Bus Type-C Alternate mode. (See attached diagram.) Figure 4F and Figure 4G As shown, the second transmitting device TX may have a physical button BUT, and the button BUT can be used to notify the receiving device RX to output the second image signal IM2 transmitted by the second information processing device NB2 to the display DIS. The control signal CTL issued by the first application interface APP1 of the first information processing device NB1 can be used to disable the button BUT of the second transmitting device TX, but is not limited thereto.

[0067] It should be noted that, in the preceding embodiments, "disabling at least one function of the second transmitting device TX2" can be, for example, preventing the second transmitting device TX2 from projecting, preventing the second transmitting device TX2 from wirelessly outputting audio and video packets, or preventing the button BUT of the second transmitting device TX2 from being triggered by user pressing (e.g. Figure 4F and Figure 4G (as shown), but not limited to this.

[0068] In another embodiment, assuming that the level of the first permission AU1 (e.g., teacher permission) of the first transmitting end device TX1 is higher than the level of the second permission AU2 (e.g., student permission) of the second transmitting end device TX2, the first application interface APP1 of the first information processing device NB1 can also send a control signal CTL to disable at least one function of the second application interface APP2 of the second information processing device NB2, but is not limited thereto.

[0069] For example, such as Figure 5A As shown, the control signal CTL issued by the first application interface APP1 of the first information processing device NB1 can be directly transmitted to the second information processing device NB2 to disable at least one function of the second application interface APP2 of the second information processing device NB2, but is not limited thereto.

[0070] like Figure 5B As shown, the control signal CTL issued by the first application interface APP1 of the first information processing device NB1 can be transmitted sequentially to the second information processing device NB2 via the first transmission end device TX1 and the second transmission end device TX2 to disable at least one function of the second application interface APP2 of the second information processing device NB2, but is not limited thereto.

[0071] like Figure 5C As shown, the control signal CTL issued by the first application interface APP1 of the first information processing device NB1 can be transmitted to the second information processing device NB2 in sequence via the first transmitting end device TX1, the first receiving end device RX1 and the second transmitting end device TX2 to disable at least one function of the second application interface APP2 of the second information processing device NB2, but is not limited thereto.

[0072] Please refer to Figure 6A and Figure 6B , Figure 6A An embodiment of a first application driver AD1 of a first information processing device NB1 is illustrated, which provides a first application interface APP1 based on a first permission AU1. Figure 6B An embodiment of a second application driver AD2 of a second information processing device NB2 is illustrated, which provides a second application interface APP2 based on a second permission AU2.

[0073] like Figure 6A and Figure 6B As shown, assuming that the level of the first permission AU1 (e.g., teacher permission) of the first transmitting device TX1 is higher than the level of the second permission AU2 (e.g., student permission) of the second transmitting device TX2, then the number of functions of the first application interface APP1 provided by the first application driver AD1 of the first information processing device NB1 based on the first permission AU1 (e.g., teacher permission) will be greater than the number of functions of the second application interface APP2 provided by the second application driver AD2 of the second information processing device NB2 based on the second permission AU2 (e.g., student permission) (e.g., sending a screen projection request, displaying groups, etc.). Furthermore, the operation request (e.g., screen projection request) sent by the student through the second application interface APP2 must be approved by the teacher through the first application interface APP1 before subsequent actions can be performed, but this is not a limitation.

[0074] Furthermore, the first application interface APP1 of the first information processing device NB1, which has a higher access level, can control the screen projection display mode of the display DIS via the first receiving device RX1. For example, a teacher can operate the first application interface APP1 to specify that the display DIS displays a single projection window WD (such as...) in the screen projection display mode. Figure 7A (as shown) or multiple projection windows WD1~WD4 (such as) Figure 7B (as shown), but not limited to this.

[0075] When the second application interface APP2 of the second information processing device NB2 with a lower permission level sends a screen projection request to the first receiving device RX1, the first receiving device RX1 will first notify the first application interface APP1 of the first information processing device NB1 with a higher permission level, and only after the first application interface APP1 agrees will the first receiving device RX1 transmit the screen projection screen provided by the second application interface APP2 to the display DIS for display according to the screen projection request, but this is not the only limitation.

[0076] Next, we will use a real classroom scenario as an example to explain in detail.

[0077] Assuming there is one teacher (Host) and multiple students (Guest) in the same classroom, when the teacher (Host) couples a first transmitting device TX1 with first permission AU1 (a higher permission level) to a first information processing device NB1, the first application driver AD1 of the first information processing device NB1 will provide, according to the first permission AU1, the following... Figure 6AThe first application interface APP1 shown is used by the teacher (Host), and the first transmitting device TX1 will automatically connect to the first receiving device RX1 in the classroom to simplify the originally cumbersome pre-setup process; when the student (Guest) couples the second transmitting device TX2 with the second permission AU2 (lower permission level) to the second information processing device NB2, the second application driver AD2 of the second information processing device NB2 will provide, according to the second permission AU2, such as Figure 6B The second application interface APP2 shown is for use by students (Guests), and the second transmitting device TX2 will automatically connect to the first receiving device RX1 in the classroom to simplify the originally cumbersome pre-setup process.

[0078] In the aforementioned classroom setting, the present invention can achieve at least the following three functions:

[0079] Feature 1: Both teachers (Host) and students (Guest) can use the screen mirroring function, but the screen mirroring function of students (Guest) will be restricted by teachers (Host).

[0080] For example, in Figure 7A In the single-window projection mode shown, the screens of all participants are presented similarly to those in Google Meet, but only the teacher (Host) can specify a single screen to be projected onto the monitor DIS via the first application interface APP1. Figure 7B In the split-window projection mode shown, the presentation of all participants' screens is similar to that of Google Meet, but only the teacher (Host) can specify the split screen to be projected onto the monitor DIS through the first application interface APP1.

[0081] Function 2: The teacher (Host) can approve / reject the operation request made by the student (Guest).

[0082] For example, regardless of Figure 7A The single-window projection mode shown or Figure 7B In the split-window projection mode shown, the teacher (Host) can project their own or any student's (Guest) screen onto the monitor DIS via the first application interface APP1. Students (Guests) can share their screens onto the monitor DIS via methods such as... Figure 6B The second application interface shown, APP2, sends a screen mirroring request. When the teacher (Host) uses the interface as shown... Figure 6A When the first application interface APP1 receives a student's screen mirroring request message, the teacher (Host) can choose to agree or reject the student's screen mirroring request in order to proceed with subsequent actions.

[0083] Feature 3: The teacher (Host) can use the functions of grouping and initiating polls, while students only have the function of voting.

[0084] For example, when classroom activities require group work, the teacher (Host) can do so through methods such as... Figure 6A The first application interface, APP1, shown below, groups online students (Guests), and students (Guests) can instantly... Figure 6B The second application interface, APP2, shows the user's assigned group information. Furthermore, teachers (Hosts) can also use it during classroom instruction. Figure 6A The first application interface, APP1, shows the process of asking questions and providing options, which students (Guests) can then immediately access. Figure 6B The second application interface APP2 shows the questions and options and allows users to vote. Finally, the teacher (Host) can see the students' (Guest) voting results through the first application interface APP1.

[0085] It should be noted that although the above embodiments are illustrated using a classroom setting with teachers and students conducting video conferences as an example, the present invention can also be applied to other video conference settings, such as a lecture setting with speakers and listeners, a company setting with managers and subordinates conducting video conferences, or any other video conference setting, without any specific limitations.

[0086] In practical applications, such as Figure 8 As shown, different operating system platforms (such as Android, iOS, Windows, Mac, etc.) can directly execute different functions (such as start mirroring F1, whiteboard F2, screen projection F3, broadcast F4, etc.) within the same network domain through the website WEB / APP of the receiving terminal device RX with control command and location vector functions, thereby improving the compatibility and convenience of the video conferencing system in actual operation, but not limited to this.

[0087] Another embodiment of the present invention provides an automatic identity recognition method for use in video conferencing systems. In practical applications, this automatic identity recognition method can be applied to various types of video conferencing scenarios, but is not limited thereto.

[0088] Please refer to Figure 9 , Figure 9 A flowchart illustrating the automatic identification method in this embodiment is shown. For example... Figure 9 As shown, the automatic identification method may include the following steps:

[0089] Step S10: The user couples the transmitting device to the information processing device;

[0090] Step S12: The transmitting device transmits the identity information to the information processing device;

[0091] Step S14: The application driver of the information processing device determines whether the user of the transmitting device has first or second permissions based on the identity information;

[0092] Step S16: If the determination result of step S14 is that the user has first permission, then open the first application interface corresponding to the first permission and automatically connect the transmitting end device and the corresponding receiving end device; and

[0093] Step S18: If the judgment result of step S14 is that the user has the second permission, then open the second application interface corresponding to the second permission and automatically connect the transmitting end device with the corresponding receiving end device.

[0094] For example, suppose there is a wireless projector (RX) in a classroom, and the laptops of a teacher (Host) and several students (Guests) have applications pre-installed. When the teacher (Host) plugs the teacher's transmitter (Host TX) into the laptop, the teacher's transmitter (Host TX) transmits the teacher's (Host's) identity information to the laptop. The laptop's application driver determines the teacher's (Host's) permissions based on the identity information and opens the teacher's (Host's) application interface accordingly. At the same time, the teacher's transmitter (Host TX) automatically connects to the wireless projector (RX) via the classroom's wireless network, simplifying the originally cumbersome pre-setup process and enabling the teacher's transmitter (Host TX) to achieve a true "plug and play" effect when coupled to the laptop.

[0095] Similarly, when a student plugs the Guest TX into a laptop, the Guest TX transmits the student's identity information to the laptop. The laptop's application driver determines the student's permissions based on the identity information and opens the corresponding application interface for the student to use. At the same time, the Guest TX automatically connects to the wireless projector (RX) via the classroom's wireless network, simplifying the originally cumbersome setup process and enabling the Guest TX to achieve a true "plug and play" effect when coupled to the laptop.

[0096] It should be noted that since the teacher version transmitter (Host TX), student version transmitter (Guest TX), and wireless projection device (RX) each have their own defined identity data (Config), when the teacher version transmitter (Host TX) or student version transmitter (Guest TX) is plugged into a laptop, the laptop's application driver can automatically recognize the teacher (Host) or student (Guest) identity and automatically open their dedicated application interface. At the same time, it will automatically establish a connection between the teacher version transmitter (Host TX) or student version transmitter (Guest TX) and the wireless projection device (RX).

[0097] In one embodiment, the identity data (RX Config) of the wireless projection device can be stored in the application driver of the laptop computer. When the teacher version transmitter (Host TX) or student version transmitter (Guest TX) is plugged into the laptop computer, the application driver of the laptop computer can compare the identity data (RX Config) of the wireless projection device with the identity data (Host TX Config) of the teacher version transmitter (Host TX Config) or student version transmitter (Guest TX Config). If the match is successful, its dedicated application interface will be automatically opened and a connection between the teacher version transmitter (Host TX) or student version transmitter (Guest TX) and the wireless projection device (RX) will be automatically established at the same time.

[0098] In another embodiment, when the teacher version transmitter device (Host TX) or the student version transmitter device (Guest TX) is plugged into the laptop, the laptop's application driver can first obtain the wireless projection device's identity information (RX Config) from the wireless projection device (RX), and compare it with the identity information of the teacher version transmitter device (Host TX Config) or the student version transmitter device (Guest TX Config) according to the transmitter device matching list in the wireless projection device's identity information (RX Config). If the match is successful, its dedicated application interface will be automatically opened and a connection between the teacher version transmitter device (Host TX) or the student version transmitter device (Guest TX) and the wireless projection device (RX) will be automatically established at the same time.

[0099] It should be noted that although the above embodiments are illustrated using a classroom setting with teachers and students conducting video conferences as an example, the present invention can also be applied to other video conference settings, such as a lecture setting with speakers and listeners, a company setting with managers and subordinates conducting video conferences, or any other video conference setting, without any specific limitations.

[0100] Compared to previous technologies, this invention can not only automatically identify the unique identity of different users' transmitting devices (TX) and automatically provide a dedicated application interface with corresponding permissions in video conferencing scenarios, but also enable the transmitting device to automatically connect to the correct receiving device (RX). This greatly simplifies the originally complicated video conferencing pre-setup process, allowing different users' transmitting devices to achieve a "plug and play" effect when coupled to the information processing device. In addition, the receiving device (RX) with control command and position vector functions can be compatible with different operating system platforms (such as Android, iOS, Windows, Mac, etc.) used by different participants, thus effectively improving the convenience and satisfaction of users when operating in video conferencing scenarios.

[0101] The present invention has been described in the above-described embodiments; however, these embodiments are merely examples for implementing the present invention. It must be noted that the disclosed embodiments do not limit the scope of the present invention. Conversely, any modifications and refinements made without departing from the spirit and scope of the present invention are within the scope of patent protection of the present invention.
