Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to a video conferencing system. Background Technology

[0002] In recent years, with the rapid development of the Internet and audio-visual processing, multiple users in different locations can simultaneously connect via video using electronic devices such as computers, smartphones, and tablets. When users are making voice calls, they can also see the dynamic images of other users on their screens, 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, in a video conferencing system, the transmitter (TX) and receiver (RX) are wirelessly connected. The transmitter can connect to an information processing device, and the receiver can connect to a video conferencing screen management device. In a traditional video conferencing scenario, when the transmitter ends its screen sharing, the receiver enters a standby state and continues to output a standby image to the video conferencing screen management device. The video conferencing screen management device continues to transmit the standby image to the monitor, causing the portion of the video conferencing system screen displayed on the monitor to be occupied by the standby image. For example... Figure 1 The standby screen SB occupies part of the video conferencing system screen 1, which needs further improvement.

[0004] Therefore, it is necessary to design a new type of video conferencing system to overcome the above-mentioned shortcomings. Summary of the Invention

[0005] The purpose of this invention is to provide a video conferencing system that can effectively solve the problem of standby screens occupying the video conferencing system screen.

[0006] To achieve the above objectives, the present invention provides a video conferencing system, comprising: a transmitting end device for connecting to an information processing device; and a receiving end device for wirelessly connecting to the transmitting end device, wherein the receiving end device wirelessly receives audio and video data about the information processing device transmitted by the transmitting end device, and when the receiving end device triggers a standby screen and is connected to a video conferencing screen management device, the receiving end device does not output the standby screen to the video conferencing screen management device.

[0007] Preferably, the transmitting device has a physical button, which triggers the wireless transmission of the real-time image of the information processing device to the receiving device, and the receiving device then transmits the real-time image to the video conferencing screen management device; when the transmitting device triggers the end of screen sharing through the physical button, the receiving device generates the standby screen.

[0008] Preferably, when the transmitting device is not connected to the receiving device, the receiving device outputs the standby screen as an online operation scenario. If the receiving device is connected to the video conferencing screen management device, the receiving device does not output the standby screen to the video conferencing screen management device.

[0009] Preferably, the receiving device has a first port, which is connected to the video conferencing screen management device through a first channel. The receiving device sets the first port so that the first channel does not output or is turned off, thus preventing the output of the standby screen to the video conferencing screen management device.

[0010] Preferably, the receiving device includes an image processing unit coupled to the first port, and the image processing unit does not output the standby screen to the first port.

[0011] Preferably, the receiving device and the video conferencing screen management device determine that the receiving device is connected to the video conferencing screen management device through extended display capability identification exchange.

[0012] Preferably, the receiving device and the video conferencing management device determine the connection of the receiving device to the video conferencing management device by sending back Universal Serial Bus control signals or High Definition Multimedia Interface Consumer Electronics Control signals.

[0013] Preferably, when the transmitting device does not trigger the screen sharing function or interrupts the connection between the transmitting device and the receiving device and does not wirelessly transmit the screen of the connected information processing device to the receiving device, the receiving device triggers the standby screen.

[0014] Preferably, when the receiving device triggers the standby screen and the receiving device is connected to the first display, the receiving device outputs the standby screen to the first display.

[0015] Preferably, the receiving device has a second port, which is connected to the first display via a second channel. The first display receives the standby screen, while the video conferencing screen management device does not receive the standby screen.

[0016] Preferably, the video conferencing screen management device is also connected to a second display. When the video conferencing screen management device receives multiple video conferencing screens, the video conferencing screen management device allocates these video conferencing screens to be displayed in different display areas of the second display, and these video conferencing screens do not include the standby screen from the receiving device.

[0017] Preferably, the video conferencing screen management device is connected to the second display via a third channel, and the third channel is a high-definition multimedia interface channel.

[0018] Preferably, the video conferencing screen management device is also connected to a camera, which acquires the video conferencing screen and provides the video conferencing screen to the video conferencing screen management device.

[0019] Compared with the prior art, the video conferencing system provided by the present invention, when operating in a video conferencing scenario, once the transmitting device ends screen sharing and the receiving device is in standby mode, the receiving device does not output the standby screen to the video conferencing screen management device, so that the video conferencing screen management device cannot display the standby screen on the video conferencing system screen of the display. Therefore, it can effectively solve the problem of the standby screen occupying part of the video conferencing system screen in the prior art. Attached Figure Description

Detailed Implementation

[0021] 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.

[0022] Certain terms are used in the specification and claims to refer to specific elements. It will be understood by those skilled in the art that manufacturers may use different names to refer to the same element. This specification and claims do not distinguish elements by differences in name, but rather by differences in function. The term "comprising" throughout the specification and claims is an open-ended term and should be interpreted as "comprising but not limited to".

[0023] Please refer to Figure 2 , Figure 2 This is a schematic diagram of a video conferencing system provided in an embodiment of the present invention. Figure 2 As shown, the video conferencing system 2 includes a transmitting device TX and a receiving device RX. The transmitting device TX is connected to the information processing device NB. The receiving device RX is wirelessly connected to the transmitting device TX. The receiving device RX wirelessly receives audio and video data DAT transmitted by the transmitting device TX regarding the information processing device NB.

[0024] In practical applications, the video conferencing system provided by this invention is applicable to various types of video conferencing scenarios, enabling multiple users in different locations to conduct video conferences with image and sound transmission simultaneously through electronic devices such as computers, smartphones, and tablets. Furthermore, the standby screen triggered by the receiving device will not appear in the video conferencing system screen seen by all users, but this is not a limitation.

[0025] When the receiving device RX triggers the standby screen SB and is connected to the video conferencing screen management device VM, the receiving device RX does not output the standby screen SB to the video conferencing screen management device VM. However, when the receiving device RX triggers the standby screen SB and is connected to the display DIS, the receiving device RX will output the standby screen SB to the display DIS.

[0026] It should be noted that when the transmitting device TX does not trigger the video sharing function or interrupts the connection between the transmitting device TX and the receiving device RX and fails to wirelessly transmit the audio and video data (DAT) of the connected information processing device NB to the receiving device RX, the receiving device RX will trigger the standby screen SB. When the transmitting device TX is not connected to the receiving device RX, the receiving device RX outputs the standby screen SB in the context of an online operation. If the receiving device RX is connected to the video conferencing screen management device VM, the receiving device RX will not output the standby screen SB to the video conferencing screen management device VM.

[0027] In practical applications, the video conferencing system 2 may also include multiple transmitting end devices, and the video conferencing screen management device VM may also be coupled to devices such as one or more monitors and cameras. The video conferencing screen management device VM can manage the multiple video conferences it receives to allocate the video conference screens to be displayed in different display areas of the monitor, and the video conference screens do not include the standby screen SB from the receiving end device RX, but are not limited thereto.

[0028] The connection between the transmitting device TX and the information processing device NB can be, for example, an HDMI interface, a Universal Serial Bus (USB) Type-C Alternate mode interface, or an interface that allows the transmitting device TX to become a virtual display through Extended Display Identification Data (EDID) exchange, but is not limited thereto. In addition, the connection between the transmitting device TX and the information processing device NB can be a Universal Serial Bus (USB) interface, with software loaded in the information processing device NB to capture the real-time image of the information processing device NB and output it to the transmitting device TX, but is not limited thereto.

[0029] As for the communication between the receiving device RX and the video conferencing management device VM, it can be determined whether the receiving device RX is connected to the video conferencing management device VM by exchanging Extended Display Capability Identifier (EDID), or by sending back Universal Serial Bus (USB) control signals or High Definition Multimedia Interface (HDMI) Consumer Electronics Control (CEC) signals, but this is not the only method.

[0030] Please refer to Figure 3 , Figure 3 This is a schematic diagram of a video conferencing system provided according to another embodiment of the present invention. Figure 3 As shown, the video conferencing system 3 includes multiple transmitting devices TX1~TX3 and receiving devices RX. Transmitting devices TX1~TX3 are respectively connected to information processing devices NB1~NB3. Transmitting devices TX1~TX3 are wirelessly connected to receiving devices RX. Receiving devices RX wirelessly receive audio and video data DAT1~DAT3 transmitted from transmitting devices TX1~TX3 regarding information processing devices NB1~NB3.

[0031] When the transmitting end devices TX1~TX3 do not trigger the screen sharing function or interrupt the connection between the transmitting end devices TX1~TX3 and the receiving end device RX and do not wirelessly transmit the audio and video data DAT1~DAT3 of the connected information processing devices NB1~NB3 to the receiving end device RX, the receiving end device RX will trigger the standby screen SB.

[0032] It should be noted that the standby screen SB at this time can be information about how the transmitting devices TX1~TX3 are connected to the receiving device RX, but is not limited to this. In practical applications, the receiving device RX and the video conferencing management device VM can determine the connection between the receiving device RX and the video conferencing management device VM through Extended Display Capability Identification (EDID) exchange, Universal Serial Bus (USB) control signals, or High Definition Multimedia Interface (HDMI) Consumer Electronics Control (CEC) signal feedback, but are not limited to this.

[0033] When the receiving device RX triggers the standby screen SB and is connected to the video conferencing management device VM, the receiving device RX does not output the standby screen SB to the video conferencing management device VM. When the transmitting devices TX1~TX3 are not connected to the receiving device RX, the receiving device RX outputs the standby screen SB in an online operation scenario. If the receiving device RX is connected to the video conferencing management device VM, the receiving device RX does not output the standby screen SB to the video conferencing management device VM.

[0034] In practical applications, the receiving device RX may have a first port P1, and the first port P1 can be connected to the video conferencing management device VM via a first channel HDMI1 (e.g., a high-definition multimedia interface channel). The receiving device RX can configure the first port P1 to prevent the first channel HDMI1 from outputting or to disable the output of the standby screen SB to the video conferencing management device VM, but this is not a limitation. The receiving device RX may include a graphics processing unit (GPU), which is coupled to the first port P1 and does not output the standby screen SB to the first port P1. The GPU may be located within a central processing unit (CPU) (e.g.,...). Figure 3 (as shown) or outside the central processing unit (CPU), there are no specific restrictions.

[0035] In addition, the receiving device RX may have a second port P2, and the second port P2 can be connected to the display DIS1 via a second channel HDMI2 (e.g., a high-definition multimedia interface channel). When the receiving device RX triggers the standby screen SB and the receiving device RX is connected to the display DIS1, the receiving device RX will output the standby screen SB to the display DIS1 via the second port P2, but this is not a limitation.

[0036] In other words, when the receiving device RX triggers the standby screen SB and the receiving device RX is connected to the video conferencing screen management device VM and the display DIS1 through the first channel HDMI1 and the second channel HDMI2 respectively, the display DIS1 will receive the standby screen SB from the receiving device RX, but the video conferencing screen management device VM will not receive the standby screen SB from the receiving device RX, but this is not a limitation.

[0037] In this embodiment, the video conferencing management device VM can be connected to the display DIS2 via a third HDMI channel (e.g., a high-definition multimedia interface channel). When the video conferencing management device VM receives multiple video conferencing feeds from different participants (e.g., ...), Figure 4 When video conference frames V1-V2 are displayed, the video conference frame management device VM will allocate these video conference frames to different areas of the video conference system frame 4 displayed on the monitor DIS2, and these video conference frames do not include the standby frame SB from the receiving device RX. In practical applications, the video conference frame management device VM can also be connected to a camera CAM. The camera CAM is used to acquire video conference frames and provide them to the video conference frame management device VM, but is not limited to this.

[0038] Please refer to the following: Figure 5 .like Figure 5 As shown, taking the transmitting device TX1 as an example, the transmitting device TX1 can be connected to the port PT of the information processing device NB1 via a TYC cable (e.g., a cable supporting Universal Serial Bus (USB), High Resolution Multimedia Interface (HDMI), or Universal Serial Bus (USB) Type-C alternative mode). The transmitting device TX1 is equipped with a physical button BUT, which can be triggered (e.g., a user pressing the physical button BUT) to activate the screen sharing function, wirelessly transmitting the audio-visual data DAT1 (e.g., the real-time video conferencing screen V1 of the information processing device NB1) to the receiving device RX. Then, the receiving device RX transmits the audio-visual data DAT1 to the video conferencing screen management device VM, and the video conferencing screen management device VM displays the video conferencing screen V1 of the information processing device NB1 on the video conferencing system screen 5 of the display DIS2.

[0039] When the transmitting device TX1 terminates the screen sharing function via a physical button BUT (e.g., a user presses the physical button BUT), the receiving device RX generates a standby screen SB. At this time, if the receiving device RX is connected to the video conferencing screen management device VM, the receiving device RX will not output the standby screen SB to the video conferencing screen management device VM. Therefore, the video conferencing screen management device VM cannot display the standby screen SB in the video conferencing system screen 5 of the display DIS2. That is, the video conferencing system screen 5 displayed on the display DIS2 does not include the standby screen SB from the receiving device RX, thus effectively preventing the standby screen SB from occupying part of the video conferencing system screen. The situation for the other transmitting devices TX2~TX3 can be deduced similarly, and will not be elaborated further here.

[0040] In summary, when the video conferencing system of the present invention operates in a video conferencing context, once the transmitting device ends screen sharing and the receiving device enters a standby state, the receiving device does not output a standby screen to the video conferencing screen management device. This prevents the video conferencing screen management device from displaying the standby screen on the video conferencing system screen of the monitor. Therefore, it effectively solves the problem in the prior art where the standby screen occupies part of the video conferencing system screen. 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.
