Description

Technical Field

[0001] The present invention discloses a method and system for image sharing and conference participant identification, and more particularly, a method and system for image sharing and conference participant identification with two-way communication, split screen, and voice prompt functions. Background Art

[0002] With the rapid advancement of technology, various projector systems and conference presentation systems have rapidly developed and are now being used in daily life. Conference presentation systems can be integrated with projector systems to increase the convenience of presenters when presenting information. Currently, most conference presentation systems utilize wireless communication for data transmission. Wireless communication data transmission can be categorized into two modes. In the first mode, the computers used by meeting participants must have specific software installed, which allows the computer to identify devices such as hard drives, Universal Serial Bus (USB), or CD-ROMs. Data from these physical or virtual storage devices is then transmitted to a screen or display via a wireless network. In the second mode, the computers used by meeting participants connect to a transmitting device. Once the transmitting device establishes a connection with the screen or display via a receiving device, the data stored on the computer can be projected onto the screen or display. In recent years, the use of wireless communication for data transmission in conference presentations has increased operational efficiency and convenience.

[0003] Furthermore, the ability to share conference video has become increasingly important in recent years, particularly for multi-party conferences where discussions are held on a single screen. When multiple users are connected remotely, their private registration information may be false or incorrect. For example, a user may register a conference server account using Google or Facebook information. However, Google or Facebook information can be altered or forged and cannot be identified by others. In other words, if at least one user in a multi-user remote conference cannot be identified, the efficiency of the discussion will be significantly reduced due to the unknown identity of the speaker, and the information security risks will also be a concern.

[0034] In order to provide a further understanding of the purpose, structure, features, and functions of the present invention, the present invention is described in detail below with reference to the embodiments.

[0035] Figure 1The block diagram of an embodiment of the image sharing and conference participant identification system 100 of the present invention is shown. The image sharing and conference participant identification system 100 includes a first multimedia adapter 10, a second multimedia adapter 11, a first display D1, and a second display D2. The first multimedia adapter 10 can be connected to the second multimedia adapter 11 wirelessly (such as Wireless Fidelity, Wi-Fi). The first display D1 is coupled to the first multimedia adapter 10. The second display D2 is coupled to the second multimedia adapter 11. In the image sharing and conference participant identification system 100, after the first multimedia adapter 10 is triggered, the system can generate a connection control signal. The first multimedia adapter 10 can transmit the connection control signal to the second multimedia adapter 11 directly or through the server SER based on the connection list. Subsequently, a connection can be established between the first multimedia adapter 10 and the second multimedia adapter 11. After a connection is established between the first multimedia adapter 10 and the second multimedia adapter 11, the first multimedia adapter 10 can transmit the first image data to the second multimedia adapter 11 via the connection. Therefore, the second multimedia adapter 11 can integrate the first image data and its own second image data to generate shared image data and display it on the second display D2. In addition, after a connection is established between the first multimedia adapter 10 and the second multimedia adapter 11, the second multimedia adapter 11 can also transmit the second image data to the first multimedia adapter 10 via the connection. Therefore, the first multimedia adapter 10 can also integrate its own first image data and second image data to generate shared image data and display it on the first display D1. In other words, the image sharing and conference participant identification system 100 has a two-way communication function, as well as a split screen, conference participant identification, and voice prompt functions. Details will be described later.

[0036] In the image sharing and conference participant identification system 100, as Figure 1As shown, the first multimedia adapter device 10 includes a first receiving device R1 and a first multimedia adapter box M1. The first receiving device R1 and the first multimedia adapter box M1 can communicate with each other through a Universal Serial Bus Port (USB) and a High Definition Multimedia Interface (HDMI). The USB port supports the transmission of control signal packets. The High Definition Multimedia Interface supports the transmission of multimedia signal packets. The first receiving device R1 and the first multimedia adapter box M1 can also communicate with each other through a USB Type-C port. The USB Type-C port supports the transmission of control signal packets and multimedia signal packets. Alternatively, the first receiving device R1 and the first multimedia adapter box M1 can communicate with each other through an audio and video channel. The audio and video channel can support the transmission of multimedia signal packets and control signal packets encoded and embedded in the multimedia signal packets. Any reasonable communication mode and communication technology between the first receiving device R1 and the first multimedia adapter box M1 fall within the scope of the present invention. The first receiving device R1 can be connected to at least one first transmitting device. For example, the first receiving device R1 can establish a connection with the first transmitting device TX11 and the first transmitting device TX12. The first transmitting device TX11 can establish a connection with the first computer device NB11. The first transmitting device TX12 can establish a connection with the first computer device NB12. Similarly, the second multimedia adapter device 11 includes a second receiving device R2 and a second multimedia adapter box M2. The communication mode and communication technology between the second receiving device R2 and the second multimedia adapter box M2 are similar to the communication mode between the first receiving device R1 and the first multimedia adapter box M1 and will not be further described here. The second multimedia adapter box M2 can be connected to at least one second transmitting device. For example, the second receiving device R2 can establish a connection with the second transmitting device TX21 and the second transmitting device TX22. The second transmitting device TX21 can establish a connection with the second computer device NB21. The second transmission device TX22 can establish a connection with the second computer device NB22. The server SER can be connected to the first multimedia adapter box M1 and the second multimedia adapter box M2. The server SER can be any third-party server, such as a mail server, an authentication server, or a query server.

[0037] Figure 2 FIG. 1 is a schematic diagram of signal transmission in the image sharing and conference participant identification system 100 . Figure 3This diagram illustrates details of data transmission between a first computer device NB11, a first transmitter TX11, a first receiver R1, and a first multimedia adapter box M1 in an image sharing and conference participant identification system 100. Upon triggering the first receiver R1 or at least one of the first transmitters (TX11 and / or TX12) coupled to the first receiver R1, the first receiver R1 may generate a first control signal. For example, the first transmitter TX11 includes a trigger button TB1. The first receiver R1 also includes a trigger button RB1. The first transmitter TX11 or the first receiver R1 can press the trigger button TB1 or the trigger button RB1 to activate the one-touch-active connection function. After the first receiver R1 generates the first control signal, it can transmit the first control signal to the first multimedia adapter box M1 via path F3 (e.g., a first USB link). Next, the first multimedia adapter box M1 can obtain a connection list from the internal storage unit MEM1 or from the server SER to generate a connection control signal. The connection list can include the network address or network name of the second multimedia adapter device. After obtaining the network address of the second multimedia adapter device 11, the first multimedia adapter box M1 can request a connection from the second multimedia adapter device 11 via a connection control signal via path F4. Alternatively, the first multimedia adapter box M1 can establish a connection between the first multimedia adapter device 10 and the second multimedia adapter device 11 using the server SER. Subsequently, the first multimedia adapter device 10 and the second multimedia adapter device 11 can be controlled synchronously.

[0038] After the first multimedia adapter 10 and the second multimedia adapter 11 establish a connection, the first computer device NB11 can use the first transmission device TX11 to transmit the first image data to the first receiving device R1 via paths F1 and F2. The first receiving device R1 can transmit the first image data to the first multimedia adapter box M1 via a second connection (e.g., an HDMI channel, path F3). The first multimedia adapter box M1 can transmit the first image data to the second multimedia adapter box M2 within the second multimedia adapter 11 via path F4. Therefore, the second receiving device R2 can also receive the first image data via path F5. Similarly, after the first multimedia adapter 10 and the second multimedia adapter 11 establish a connection, the second computer device NB21 can use the second transmission device TX21 to transmit the second image data to the second receiving device R2 via paths F6 and F7. The second receiving device R2 can transmit the second image data to the second multimedia adapter box M2 via path F8. The second multimedia adapter box M2 can transmit the second video data via path F9 to the first multimedia adapter box M1 within the first multimedia adapter device 10. Therefore, the first receiving device R1 can also receive the second video data via path F10. As can be seen from the above, the image sharing and conference participant identification system 100 can support two-way communication, and both the first multimedia adapter box M1 and the second multimedia adapter box M2 can receive the first and second video data. Therefore, the first multimedia adapter box M1 can display the shared video data containing the first and second video data on the first display D1 via path F11. The second multimedia adapter box M2 can display the shared video data containing the first and second video data on the second display D2 via path F12.

[0039] In addition, the image sharing and conference participant identification system 100 can also support two-way communication of control signals. For example, after a connection is established between the first multimedia adapter device 10 and the second multimedia adapter device 11, the first transmitting device TX11 can transmit a first control signal to the second multimedia adapter device 11 through the first multimedia adapter device 10 (such as through a USB channel). After the second multimedia adapter device 11 receives the first control signal, it can operate according to the first control signal. Similarly, after a connection is established between the first multimedia adapter device 10 and the second multimedia adapter device 11, the second transmitting device TX21 can transmit a second control signal to the first multimedia adapter device 10 through the second multimedia adapter device 11 (such as through a USB channel). After the first multimedia adapter device 10 receives the second control signal, it can operate according to the second control signal.

[0040] As described above, the image sharing and conference participant identification system 100 can conduct bidirectional multimedia signal communication and control signal communication. Therefore, the image sharing and conference participant identification system 100 can use control signals to select the desired multimedia signal to be displayed. For example, after a connection is established between the first multimedia adapter 10 and the second multimedia adapter 11, the first display D1 coupled to the first multimedia adapter 10 can display the connection status of at least one first transmitting device (e.g., first transmitting devices TX11 and TX12) and at least one second transmitting device (e.g., second transmitting devices TX21 and TX22). After receiving the first control signal, the second multimedia adapter 11 can select the audio and video data of the second transmitting device TX21 from the at least one second transmitting device. Therefore, the audio and video data of the second transmitting device TX21 can be transmitted to the first multimedia adapter 10 via the second multimedia adapter 11. Similarly, the first multimedia adapter 10 can also select the audio and video data of the first transmitting device TX11 based on the second control signal transmitted by the second multimedia adapter 11. Since the image sharing and conference participant identification system 100 can perform two-way multimedia signal communication and control signal communication, it has very flexible operation flexibility.

[0041] Figure 4The following is a schematic diagram of a system 100 for image sharing and conference participant identification, in which the first multimedia adapter 10 uses an application program (APP) and a server (SER) to obtain the identity information of conference participants. The first transmitting device TX11 may also include an identification device ID1. The identification device ID1 can be any identity-recognizing device, such as a card reader, a near-field communication (NFC) sensor, or a fingerprint reader. The first transmitting device TX11 can use the identification device ID1 to generate a first identification signal (e.g., an employee ID card number). The first transmitting device TX11 transmits the first identification signal to the first receiving device R1 and the first multimedia adapter box M1. After obtaining permission, the application program (APP) accesses the first identification signal. The application program (APP) then controls the first multimedia adapter box M1 to transmit the first identification signal (e.g., an employee ID card number) to the server (SER) to verify the legitimacy of the first identification signal. The server (SER) can be an authentication server (Active Directory Server) used to identify the first identity information of at least one first conference participant. The server SER can respond to the first identification signal (e.g., employee ID card number) with the corresponding employee organization and details, such as company name, name, and email address, to the first multimedia switching device 10. Thus, the first multimedia switching device 10 can incorporate the identified identity information of the first conference participant into the shared image. Similarly, at least one second transmitting device (e.g., TX21) can transmit a second identification signal to the server SER via the second multimedia switching device 11 to identify the second identity information of at least one second conference participant. Furthermore, because the image sharing and conference participant identification system 100 has bidirectional communication capabilities, the first multimedia switching device 10 can also receive the second identity information of at least one second conference participant via the server SER, thereby integrating the first identity information of the at least one first conference participant and the second identity of the at least one second conference participant into the shared image data. The second multimedia switching device 11 can also receive the first identity information of at least one first conference participant via the server SER, thereby integrating the second identity information of the at least one second conference participant and the first identity of the at least one first conference participant into the shared image data.

[0042] Moreover, in the image sharing and conference participant identification system 100, identifying the identities of conference participants is not limited to using the server SER to assist in identification. For example, at least one first transmitting device (such as TX11) may send a first request signal to at least one first computer device (such as NB11). Then, at least one first computer device sends the first identity information of at least one first conference participant to at least one first transmitting device, so that at least one first transmitting device identifies the first identity information of at least one first conference participant. Similarly, at least one second transmitting device (such as TX21) may send a second request signal to at least one second computer device (such as NB21). Then, at least one second computer device sends the second identity information of at least one second conference participant to at least one second transmitting device, so that at least one second transmitting device identifies the second identity information of at least one second conference participant.

[0043] As mentioned above, the image sharing and conference participant identification system 100 can perform two-way data communication. Therefore, after data is synchronized between the first multimedia adapter 10 and the second multimedia adapter 11, the first display D1 coupled to the first multimedia adapter 10 can display the first identity information of at least one first conference participant corresponding to at least one first transmitting device, and the second identity information of at least one second conference participant corresponding to at least one second transmitting device. Similarly, the second display D2 coupled to the second multimedia adapter 11 can also display the first identity information of at least one first conference participant corresponding to at least one first transmitting device, and the second identity information of at least one second conference participant corresponding to at least one second transmitting device. Furthermore, the "conference participant identity information" can also be generated using software. For example, the first identity information of at least one first conference participant can be generated by executing software on at least one first computer device. The second identity information of at least one second conference participant can be generated by executing software on at least one second computer device. The first and second identity information can also include user login information.

[0044] Figure 5In the image sharing and conference participant identification system 100, the screen Scr1 of the first display D1 displays the images and identities UID1 to UID4 of all conference participants, the voice request V1, and a schematic diagram of the sub-image Sub1. In the image sharing and conference participant identification system 100, a voice prompt function is provided, which is described as follows. After the first transmission device TX11 in at least one first transmission device is triggered, a voice request signal can be generated. Then, the voice request signal can be transmitted by the first transmission device TX11 to the first multimedia switching device 10. After the first multimedia switching device 10 is synchronized with the second multimedia switching device 11, the visual location image of at least one conference participant can be added to the corresponding voice prompt message according to the voice request signal. For example, if Figure 5 As shown, the screen Scr1 of the first display D1 can display the identities UID1 to UID4 of the four conference participants, which can be displayed in the form of text. When the conference participant corresponding to the identity UID1 triggers the first transmission device TX11 and requests to speak, the window of the conference participant with the identity UID1 in the screen Scr1 will also display a voice request V1, which can be displayed in the form of text or a graphic. Therefore, the image displayed in the screen Scr1 can be used to clearly distinguish the identities of the conference participants and the participants who are currently speaking, thereby improving the efficiency of conference discussions. In addition, since the image sharing and conference participant identification system 100 supports two-way control signal communication, when the first transmission device TX11 is triggered to generate a voice prompt message on the screen Scr1, the second multimedia switching device 11 can send a second control signal to transmit to the first transmission device TX11 through the first multimedia switching device 10. Then, the first transmission device TX11 can activate the multimedia transceiver according to the second control signal, such as activating the microphone. And, as Figure 4 As shown, the image capture device DC1 can establish a connection with the first multimedia switching device 10. The image capture device DC1 can capture the real-time image of the conference space. The image capture device DC1 can transmit the real-time image of the conference space to the first multimedia switching device 10, so that the first multimedia switching device 10 controls the first display D1 to display the sub-image Sub1 of the real-time image of the conference space. The sub-image Sub1 can also be transmitted to the second multimedia switching device 11, so that the second display D2 synchronously displays the sub-image Sub1. Figure 5 As shown, the screen Scr1 of the first display D1 not only displays the identities of the conference participants UID1 to UID4 and the voice request V1, but also displays a real-time image of the conference space, displayed in a window called sub-image Sub1. Furthermore, after the image capture device DC1 establishes a connection with the first multimedia adapter 10 and captures the real-time image of the conference space, if the request signal from the second transmitting device (such as TX21) is approved, the real-time image of the conference space can be transmitted to the second display D2.

[0045] Figure 6 This is a schematic diagram of the visual location images displayed on the first display D1 and the second display D2 based on the first location information of the first transmitting devices TX11 to TX14 in the first conference space CR1 and the second location information of the second transmitting devices TX21 and TX22 in the second conference space CR2 in the image sharing and conference participant identification system 100. Figure 6 As shown, in the first conference space CR1, at least one first transmitting device coupled to the first multimedia switching device 10 broadcasts a first location signal. For example, the first transmitting devices TX11 to TX14 can broadcast four first location signals through ultra-wideband (UWB) technology. The first multimedia switching device 10 can detect the first location of at least one first transmitting device based on one or more first location signals. For example, the first receiving device R1 in the multimedia switching device 10 can locate the first location of the first transmitting devices TX11 to TX14 based on the four first location signals. Similarly, in the second conference space CR2, at least one second transmitting device coupled to the second multimedia switching device 11 broadcasts a second location signal. For example, the second transmitting devices TX21 to TX22 can broadcast two second location signals through ultra-wideband technology. The second multimedia switching device 11 can detect the second location of at least one second transmitting device based on one or more second location signals. For example, the second receiving device R2 within the second multimedia adapter 11 can locate the second positions of the second transmitting devices TX21 and TX22 based on the two second position signals. Furthermore, the shared image data can be embedded with the first and second position data to generate a visual location image of at least one conference participant. For example, on the screen Scr1 of the first display D1 in the first conference space CR1, representative identifiers of the first transmitting devices TX11 to TX14 corresponding to their current first positions can be displayed, such as TX11: UID1, TX12: UID2, TX13: UID3, and TX14: UID4. On the screen Scr2 of the second display D2 in the second conference space CR2, representative identifiers of the second transmitting devices TX21 to TX22 corresponding to their current second positions can be displayed, such as TX21: UID5 and TX22: UID6. Furthermore, screens Scr1 and Scr2 can simultaneously display the relative positions of all transmitting devices in the first and second conference spaces CR1 and CR2, as well as the corresponding participant identities. Therefore, members in the first conference space CR1 can understand the position distribution of the first and second conference participants by viewing the shared image SIMG1. Members in the second conference space CR2 can understand the position distribution of the first and second conference participants by viewing the shared image SIMG2.

[0046] As mentioned above, the image sharing and conference participant recognition system 100 can detect the location of each conference participant and generate voice prompts on the screen. Therefore, the image sharing and conference participant recognition system 100 can be further optimized to reduce disruptions during voice discussions. For example, after a first transmitter TX11 among at least one first transmitter is triggered and a voice request signal is granted, the image sharing and conference participant recognition system 100 can block voice input from other first transmitters among the at least one first transmitter. In other words, only one speaker can speak at a time, thereby reducing disruptions during voice discussions. Alternatively, after a first transmitter TX11 among at least one first transmitter is triggered and a voice request signal is granted, the image sharing and conference participant recognition system 100 can block voice input from other first transmitters located adjacent to the first transmitter. In other words, when a speaker is speaking, nearby speakers are silenced, thereby reducing disruptions during voice discussions.

[0047] Furthermore, in the image sharing and conference participant identification system 100, it is also possible to identify whether there is a "human voice" by analyzing the signal, thereby automatically generating a voice prompt message. For example, the first multimedia switching device 10 can receive a multimedia signal transmitted by at least one first transmitting device. Thereafter, the first multimedia switching device 10 can analyze the multimedia signal to determine whether the multimedia signal contains human voice information. Furthermore, if the multimedia signal contains human voice information, it means that the user operating the first transmitting device is speaking, and therefore, the image sharing and conference participant identification system 100 can generate a voice prompt message to be added to the visual location image of at least one conference participant. Therefore, the image sharing and conference participant identification system 100 can also automatically generate a voice prompt message to further increase the efficiency of conference discussions.

[0048] Furthermore, the image sharing and conference participant identification system 100 can also use a notification signal to inform the user whether the connection is confirmed. For example, the first multimedia adapter 10 can generate a notification signal by transmitting a connection control signal directly or via the server SER to the second multimedia adapter 11 based on the connection list. The first multimedia adapter 10 then transmits the notification signal to at least one second transmitting device coupled to the second multimedia adapter 10 via the second multimedia adapter 11. After the at least one second transmitting device receives the notification signal, if the at least one second transmitting device is triggered, a connection is established between the first multimedia adapter 10 and the second multimedia adapter 11. The notification signal can include an audio prompt signal and / or a light prompt signal to inform the user. In other words, to increase operability and security, the image sharing and conference participant identification system 100 can use a notification signal to notify the user of confirmation before establishing a connection between the first multimedia adapter 10 and the second multimedia adapter 11. Any reasonable changes in technology or hardware fall within the scope of the present invention.

[0049] Figure 7 The flowchart of the image sharing and conference participant identification system 100 is shown. The image sharing and conference participant identification method includes steps S701 to S705. Steps S701 to S705 are described as follows.

[0050] Step S701: providing a first multimedia switching device 10 and a second multimedia switching device 11;

[0051] Step S702: After the first multimedia adapter device 10 is triggered, a connection control signal is generated;

[0052] Step S703: The first multimedia switching device 10 is connected according to the list of connections, the connection control signal is transmitted directly or via the server SER to the second multimedia switching device 11;

[0053] Step S704: establishing a link between the first multimedia switching device 10 and the second multimedia switching device 11;

[0054] Step S705: The first multimedia switching device 10 transmits the first image data to the second multimedia switching device 11 via a link, so that the second multimedia switching device 11 integrates the first image data and the second image data to generate shared image data;

[0055] The details of steps S701 to S705 have been previously described and will not be repeated here. Because the image sharing and conference participant identification system 100 has a two-way communication function, the generated shared data can be shared with viewers (conference participants) in two or more conference rooms. Participants in two or more conference rooms can also control each other's multimedia signals through the two-way communication function. Furthermore, the image sharing and conference participant identification system 100 also has voice prompts and location detection functions, thereby increasing the efficiency of conference discussions through visual means.

[0056] In summary, the present invention discloses a system and method for image sharing and conference participant identification. The image sharing and conference participant identification system has a two-way multimedia signal communication function and a two-way control signal communication function. Because the image sharing and conference participant identification system has a two-way multimedia signal communication function and a two-way control signal communication function, the generated shared data and the identity identification data of each conference participant can be shared with all viewers. Furthermore, because the image sharing and conference participant identification system of the present invention also has voice prompts and location detection functions, it can increase the efficiency of conference discussions in a visual manner.
