The first transmission device TX1 is coupled to the first image signal source NB1. The second transmission device TX2 is coupled to the second image signal source NB2. The third transmission device TX3 is coupled to the third image signal source NB3. The fourth transmission device TX4 is coupled to the fourth image signal source NB4. The first transmission device TX1 , the second transmission device TX2 , the third transmission device TX3 and the fourth transmission device TX4 may be communication devices coupled to the corresponding image signal sources through hot-plug (Hot-Plugin) ports. The receiving device RX is wirelessly connected to the first transmitting device TX1, the second transmitting device TX2, the third transmitting device TX3 and the fourth transmitting device TX4 for receiving the first transmitting device TX1, the second transmitting device TX2 and the third transmitting device TX3 and the image signal from the fourth transmission device TX4. In addition, the receiving device RX may also select one transmitting device from among these transmitting devices. For example, the conference host can operate the central control operating device 10 connected to the receiving device RX to select the first transmitting device TX1. At least one display is connected to the receiving device RX for providing two display areas. lift For example, the dual display area control system 100 may include a first display D1 and a second display D2. The first display D1 is used to display the first display area R1. The second display D2 is used to display the second display area D2. The first display area R1 can display the report content of the meeting, such as text content or picture content. The second display area R2 can display the member list of the conference, such as the list of users operating the first transmission device TX1, the second transmission device TX2, the third transmission device TX3 and the fourth transmission device TX4 (represented by USER A to USER D). ). In the dual display area control system 100 , any reasonable technical changes or hardware replacements fall within the scope of the disclosure. For example, the control system 100 with dual display areas can introduce Q transmission devices and Q image signal sources, where Q can be any positive integer greater than two. The control system 100 with dual display areas may also introduce a single display to present the first display area R1 and the second display area R2 in a split-screen or picture-in-picture manner. However, in order to simplify the description, the first transmission device TX1 and the second transmission device TX2 will be used for description hereinafter.

In the dual display area control system 100, the first video signal source NB1 and the second video signal source NB2 are respectively connected to the first transmission device TX1 and the second transmission device TX2. Then, the receiving device RX can be paired with the first transmitting device TX1 and the second transmitting device TX2 to establish the connection between the receiving device RX and the first transmitting device TX1 and the second transmitting device TX2. After the first transmission device TX1 is triggered (eg, triggered by a hot key or a timer), the first video signal source NB1 transmits the first video signal to the first transmission device TX1. The first transmitting device TX1 processes the first video signal and transmits the first video signal to the receiving device RX. Similarly, after the second transmission device TX2 is triggered (eg, triggered by a hot key or a timer), the second video signal source NB2 transmits the second video signal to the second transmission device TX2. The second transmitting device TX2 processes the second video signal and transmits the second video signal to the receiving device RX. The receiving device RX can identify the first transmitting device TX1 and the second transmitting device TX2, and select a transmitting device between the first transmitting device TX1 and the second transmitting device TX2, for example, selecting the first transmitting device TX1. Then, after the first transmitting device TX1 is selected, the receiving device RX can display the first image signal corresponding to the first transmitting device TX1 in the first display area. The first image signal may include the projection generated by the first image signal source NB1. Therefore, the first display area can present the content generated by the first video signal source NB1. The receiving device RX can also display the identification information of the first transmitting device TX1 and the second transmitting device TX2 in the second display area R2.

In the dual display area control system 100, the receiving device RX needs to identify the first transmitting device TX1 and the second transmitting device TX1, so as to accurately identify the source of the received image signal and control a specific transmitting device. The receiving device RX may use different patterns to identify the first transmitting device TX1 and the second transmitting device TX2, as described below. In the first mode, after the first transmission device TX1 and the second transmission device TX2 are respectively connected to the first video data source NB1 and the second video data source NB2, the first transmission device TX1 and the second transmission device TX2 can directly The identification information is generated, so that the receiving device RX identifies the first transmitting device TX1 and the second transmitting device TX2 according to the identification information. The identification information can be any information used to distinguish the first transmission device TX1 and the second transmission device TX2. For example, the identification information may include specific image information, user's mugshot information, hardware username, communication software account and/or email username information, and the like. If the first image data source NB1 and the second image data source NB2 are two notebook computers, the screen images of the first image data source NB1 and the second image data source NB2 can also display two sub-subs corresponding to the identification information respectively. image. In the second mode, the receiving device RX can send a request signal to the first transmitting device TX1 and the second transmitting device TX2. After the first transmission device TX1 and the second transmission device TX2 receive the request signal, they can transmit the identification information of the first video signal source NB1 and the second video signal source NB2 to the first transmission device TX1 and the second transmission device TX2 through the first transmission device TX1 and the second transmission device TX2. Receiver RX. In the third mode, the receiving device RX can set the first transmitting device TX1 and the second transmitting device TX2, so that the first transmitting device TX1 and the second transmitting device TX2 display different identification features. For example, the first transmission device TX1 and the second transmission device TX2 have light-emitting diodes (LEDs). For example, the receiving device RX may set the LED of the first transmitting device TX1 to display red, and the LED of the second transmitting device TX2 to display blue. In addition, the identification features (such as colors) displayed by the first transmission device TX1 and the second transmission device TX2 correspond to those displayed in the second display area R2 Identification information of the first transmission device TX1 and the second transmission device TX2. For example, in Figure 1, the second display area R2 displayed on the second display D2 includes a member list. If the LED of the first transmission device TX1 is set to red, the text corresponding to "USER A" in the member list can be displayed in a red tone. If the LED of the second transmission device TX2 is set to blue, the text corresponding to "USER B" in the member list can be displayed in a blue tone. In the fourth mode, the receiving device RX can control the two identification images displayed by the first image signal source NB1 and the second image signal source NB2 through the first transmitting device TX1 and the second transmitting device TX2. For example, if the first video signal source NB1 and the second video signal source NB2 are two notebook computers, the receiving device RX can make the first video signal source NB1 and The screen of the second image signal source NB2 displays the designated image (or text) respectively. In addition, the two identification images displayed by the first image signal source NB1 and the second image signal source NB2 correspond to the identification information of the first transmission device TX1 and the second transmission device TX2 displayed in the second display area R2. For example, the receiving device RX can display the trademark of the manufacturer A on the screen of the first video signal source NB1 through the first transmitting device TX1. The receiving device RX can display the trademark of the manufacturer B on the screen of the second video signal source NB2 through the second transmitting device TX2. Then, the second display area R2 displayed on the second display D2 can display the information of the member list. The member list can also directly identify all members with images of different trademarks. Any reasonable technical changes belong to the scope disclosed by the present invention.

FIG. 2A is a schematic diagram of the first display area R1 and the second display area R2 displayed on the dual displays in the first mode in the control system 100 with dual display areas. FIG. 2B is a schematic diagram illustrating that the first display area R1 and the second display area R2 are displayed on the dual displays in the second mode in the control system 100 with dual display areas. FIG. 2C is a schematic diagram of the first display area R1 and the second display area R2 displayed on the dual displays in the third mode in the control system 100 with dual display areas. As mentioned above, the dual display area control system 100 has a first display area R1 and a second display area R2. The sizes of the first display area R1 and the second display area R2 can be customized. The display mode of the first display area R1 and the second display area R2 can also be the display mode of dual monitors of dual monitors, or the display mode of dual monitors. The multi-screen display mode, or the single-monitor with split screen or picture-in-picture display mode, are explained as follows. In FIG. 2A, the first display area R1 can be presented by the first display D1. The second display area R2 can be presented with the second display D2. Therefore, the width W1 of the first display region R1 can be the image width supported by the first display D1. In addition, the first display area R1 can display dynamic conference content images (eg, video files). The second display area R2 can display static member list data (eg, a text file). Therefore, the image quality of the first display area R1 can be set higher than that of the second display area R2, so as to improve the user's visual experience. In FIG. 2B, the first display area R1 includes the display area of the first display D1 and a part of the display area of the second display D2. When the interval between the first display D1 and the second display D2 is G1, the width of the first display area R1 is equal to W2-G1. The display mode of FIG. 2B can be regarded as a multi-screen display mode of dual monitors. In FIG. 2C, the first display area R1 includes the display area of the first display D1 and most of the display area of the second display D2. When the interval between the first display D1 and the second display D2 is G2, the width of the first display area R1 is equal to W3-G2. The display mode of FIG. 2C can also be regarded as a multi-screen display mode of dual monitors. However, in FIG. 2C, in order to maximize the range of the first display area R1, the dual display area control system 100 may compress the range of the second display area R2. In this way, the range of the first display area R1 can be improved when the conference content is presented in the multi-screen display mode of dual monitors. The width W3 of the second display area R2 can even approach the full screen width of the two displays ( D1 and D2 ).

In addition, in the dual display area control system 100, the receiving device RX also has the function of instantly selecting another transmitting device to deliver images, and dynamically adjusting the personnel list. For example, after the receiving device RX first selects the first transmitting device TX1, the first image signal sent by the first transmitting device TX1 can be placed on the first display area R1 through the receiving device RX. In addition, the identification features of the first transmitting device TX1 currently selected by the receiving device RX can also be marked on the second display area R2, such as text or images displayed in high brightness, text displayed in bold, or different text or image displayed in color. Next, the receiving device RX may select the second transmitting device TX2 among the first transmitting device TX1 and the second transmitting device TX2. After the second transmitting device TX2 is selected, the receiving device RX may The second image data corresponding to the two transmission devices TX2 are displayed in the first display area R1 to update the first display area R1. Similarly, the identification features of the second transmitting device TX2 currently selected by the receiving device RX can also be marked on the second display area R2. In other words, the receiving device RX can dynamically change the posted content in the first display area R1, and can also dynamically change the member list and the selection mark content in the second display area R2. Furthermore, as shown in FIG. 1 , the reception device RX can also be operated and set by the central control operation device 10 . For example, the conference host can use the central control operation device 10 to control the receiving device RX to select at least one transmitting device, so that the image signal of the at least one transmitting device can be displayed in the first display area R1 through the receiving device RX. In addition, the identification information of the first transmission device TX1 and the second transmission device TX2 may include the posting list information and/or identification feature information of the first transmission device TX1 and the second transmission device TX2. As mentioned above, the content of the identification information displayed in the second display area R2 may include information on the placement list (eg, information on the member list), which may be presented in text. The content of the identification information displayed in the second display area R2 may also include identification feature information (such as different trademarks, patterns of different colors, or headshot information), which can be presented by images. Any reasonable technical changes belong to the scope disclosed by the present invention.

In addition, the control system 100 with dual display areas may also introduce a touch operation mode to control the display contents of the first display area R1 and the second display area R2, as described below. When the first image data source NB1 and the second image data source NB2 are two notebook computers, the identification information may include a first identification display feature and a second identification display feature. The first identification display feature and the second identification display feature may be two different patterns or two touch areas displayed at different specific positions. In other words, the first identification display feature may be displayed in the first position of the second display area R2. The second identification display feature may be displayed in a second position of the second display area R2. The first position is different from the second position. If the first position is triggered by the first trigger event (eg, the user touches the first position of the second display area R2 ), the receiving device RX can generate a first notification signal to the first transmitting device TX1 . Then, the first transmitting device TX1 can display the first image signal in the first display area R1 through the receiving device RX. Similarly, if the second position is triggered by a second trigger event (for example, the user touches the second position of the second display area R2), the receiving device RX can generate a second notification signal to the second transmitting device TX2. Then, the second transmitting device TX2 can display the second image signal in the first display area R1 through the receiving device RX.

In the dual display area control system 100 , when the receiving device RX has not selected the transmitting device, the receiving device RX can by default deliver the image signal of the default transmitting device to the first display area R1 . After the central operating device 10 controls the receiving device RX to designate a certain transmitting device, the receiving device RX can immediately switch the default image of the first display area R1 to the image corresponding to the designated transmitting device. The receiving device RX can also generate a signal that the image switching is completed to the central control operating device 10 . The central control operation device 10 can display an indication message of the delivery completion status. In addition, the receiving device in the dual display area control system 100 can be regarded as a virtual display device, and the description is as follows. For example, when the first transmission device TX1 is coupled to the first image signal source NB1, the first transmission device TX1 can transmit the first Extended Display Identification Data (EDID) into the first image signal source the first data processing device. After the first data processing device receives the first extended display capability identification data, the first data processing device can identify the first transmission device TX1 as the first virtual display device according to the first extended display capability identification data to provide the first image The signal is sent to the first transmitting device TX1 for wireless communication. Similarly, when the second transmission device TX2 is coupled to the second image signal source NB2, the second transmission device TX2 transmits the second extended display capability identification data to the second data processing device in the second image signal source NB2. After the second data processing device NB2 receives the second extended display capability identification data, the second data processing device NB2 identifies the second transmission device TX2 as a second virtual display device according to the second extended display capability identification data, so as to provide a second virtual display device. The video signal is sent to the second transmission device TX2 for wireless communication.

FIG. 3B is a schematic diagram of the second appearance of the transmission device TX200 in the control system 100 with dual display areas. In order to avoid confusion, the transmission device in Fig. 3A is hereinafter referred to as the transmission device TX100. The transmission device in Fig. 3B is hereinafter referred to as the transmission device TX200. As shown in FIGS. 3A and 3B , the transmission device TX100 and the transmission device TX200 have a button BUT. The button BUT can be regarded as a trigger Start button for wireless pairing procedure. The button BUT can also be regarded as a control button that triggers the transmission of the image signal to the receiving device RX. For example, after the transmitting device TX100 has been paired and established with the receiving device RX, when the user presses the button BUT, the transmitting device TX100 can transmit the image signal to the receiving device RX. The receiving device RX can selectively control the first display D1 and the second display D2 to cast images according to the image signal and the operation mode of the central control operation device 10 . And, as mentioned above, the transmission device can be connected to a corresponding image data source (eg, a notebook computer). Therefore, the transmission device may have at least one data transmission port. For example, the transmission device TX100 can use the USB Type-A transmission port USB and/or the High Definition Multimedia Interface (HDMI) transmission port HDMI and corresponding images Data source link. The transmission device TX200 can be connected with the corresponding image data source through the transmission port TYC of a type C universal serial bus (USB Type-C). However, the embodiments of the present invention are not limited thereto, and any reasonable changes in the cable length, transmission port specifications, and device appearance of the transmission device fall within the scope of the present invention.

FIG. 4 is a flow chart of the control method of the dual display area executed by the dual display area control system 100 . The flowchart of the control method of the dual display area includes steps S401 to S410. Any reasonable technical changes belong to the scope disclosed by the present invention. Steps S401 to S410 are described as follows: Step S401: Connect the first video signal source NB1 and the second video signal source NB2 to the first transmitting device TX1 and the second transmitting device TX2 correspondingly; Step S402: Pair the receiving device RX with the first transmitting device TX1 and the second transmitting device TX2. A transmitting device TX1 and a second transmitting device TX2 to establish the connection between the receiving device RX and the first transmitting device TX1 and the second transmitting device TX2; Step S403: After the first transmitting device TX1 is triggered, the first image signal source NB1 Send the first image signal to the first transmission device TX1; Step S404: the first transmission device TX1 processes the first image signal, and transmits the first image signal to the receiving device RX; Step S405: After the second transmission device TX2 is triggered, the second video signal source NB2 transmits the second video signal to the second transmission device TX2; Step S406: The second transmission device TX2 processes the second video signal and transmits the second video signal to the second video signal. The signal is transmitted to the receiving device RX; Step S407: Identify the first transmitting device TX1 and the second transmitting device TX2; Step S408: Select the first transmitting device TX1 from the first transmitting device TX1 and the second transmitting device TX2; Step S409: In After the first transmitting device TX1 is selected, the first image signal corresponding to the first transmitting device TX1 is displayed in the first display area R1 through the receiving device RX; Step S410: Identify the first transmitting device TX1 and the second transmitting device TX2 The information is displayed in the second display area R2 through the receiving device RX.

The details of steps S401 to S410 have been described above, so they will not be repeated here. In the control system 100 with dual display areas, since the receiving device RX can selectively perform the delivery procedure of the image signal of at least one transmitting device, the operability for the conference host is increased. In addition, the dual display area control system 100 utilizes two display areas ( R1 and R2 ) to clearly and synchronously display the conference content sent by the transmitting device and the list of members currently connected to the receiving device. Therefore, the moderator can control or switch the posting data of the meeting (such as posting or switching to the report content of a meeting member) very intuitively and efficiently.

To sum up, the present invention describes a dual display area control system and a dual display area control method. The dual display area control system can control two display areas at the same time. One display area is used to display the delivery data corresponding to the currently designated transmitting device, and the other display area is used to display the member list currently connected to the receiving device. Therefore, the moderator of the meeting and the members of the meeting will be able to clearly understand the progress of the current meeting and the content of the present reporter.
