[0018] [Hardware architecture of a multi-computer switching device supporting image segmentation]

[0019] Please refer to Figure 1 , Figure 1 A schematic diagram of a multi-computer switching device supporting image segmentation according to an embodiment of the present invention is provided. Figure 2 A schematic diagram of a segmentation screen template of a multi-computer switching device supporting image segmentation is provided for an embodiment of the present invention. The multi-computer switching device 1 supporting image segmentation (hereinafter referred to as the multi-computer switching device for convenience of description) includes, for example, but is not limited to, a processing circuit 101, a switching circuit 103, a host connection port 105, a screen allocation circuit 107, an on-screen display (OSD) circuit 109, an operation interface 111, a setting circuit 113, and a network interface 115. The processing circuit 101 is electrically connected to the switching circuit 103, the operation interface 111, the setting circuit 113, the network interface 115, and the screen allocation circuit 107. The host connection port 105 includes, for example, a first port 1051 and a second port 1052, and the first port 1051 and the second port 1052 can be connected to the first computer host 21 and the second computer host 22, respectively.

[0020] The switching circuit 103 determines whether the first computer host 21 or the second computer host 22 can receive the input signal of the input device 40, and whether the first computer host 21 or the second computer host 22 can output the image signal to the display device 30 for display according to the input operation of the user on the operation interface 111. Here, the switching circuit 103 can control the input device 40 to be electrically connected to the first computer host 21 or the second computer host 22 according to the operation. Here, the input device 40 is, for example, a mouse or a keyboard.

[0021] For example, when the switching circuit 103 switches to select the first computer host 21 to receive an input signal, the processing circuit 101 receives the input signal of the input device 40 and outputs it to the first computer host 21 via the switching circuit 103 and the first port 1051. At this time, the processing circuit 101 can be electrically connected to the first computer host 21 through the first port 1051, and receives a first image signal sent by the first computer host 21, and outputs it to the display device 30 for display.

[0022] When the switching circuit 103 switches to select the second computer host 22 to receive the input signal, the processing circuit 101 receives the input signal of the input device 40 and outputs it to the second computer host 22 via the switching circuit 103 and the second port 1052. At this time, the processing circuit 101 can be electrically connected to the second computer host 22 through the second port 1052, and receive a second image signal sent by the second computer host 22, and output it to the display device 30 for display.

[0023] Here, the first port 1051 and the second port 1052 are two examples, but the present invention is not limited thereto, and the number of ports can be set correspondingly according to the number of computer hosts connected for use. The first image signal and the second image signal are, for example, compatible with a high-definition multimedia interface (HDMI), a display graphics array interface (VGA), a digital video interface (DVI), a D-terminal, a serial digital interface or a digital display port (DisplayPort).

[0024] In this multi-computer switching device 1, there can be multiple display devices 30 connected to the outside, and multiple display devices 30 are stacked and arranged to form a video wall. The number of display devices 30 can be set according to the display area of ​​the video wall. The display images of these display devices 30 constituting the video wall can be provided by the first image signal of the first computer host 21 and the second image signal of the second computer host 22 separately or simultaneously.

[0025] It is worth noting that the processing circuit 101 described herein can select one of the plurality of split screen templates according to a screen setting signal, and control the screen allocation circuit 107 to output at least one of the first image signal and the second image signal to these display devices 30 according to the selected split screen template, so that an integrated screen displayed by these display devices 30 in combination can conform to the corresponding display setting of the selected split screen template.

[0026] Furthermore, the operation interface 111 is electrically connected to the screen display circuit 109, and the operation interface 111 can be used to control the screen display circuit 109 to output a display such as Figure 2A template selection menu screen 5 is shown, and this template selection menu screen 5 may include, for example, a plurality of split screen templates for selection, and the template selection menu screen 5 may be displayed on at least one of the plurality of display devices 30. For example, the first split screen template 51 is composed of 4 display devices 30 arranged in a 2*2 regular pattern to form a TV wall, the second split screen template 52 is composed of 9 display devices 30 arranged in a 3*3 regular pattern to form a TV wall, the third split screen template 53 is composed of 16 display devices 30 arranged in a 4*4 regular pattern to form a TV wall, the fourth split screen template 54 is composed of 5 display devices 30 of different display sizes arranged in a TV wall, and the fifth split screen template 55 is composed of 7 display devices 30 arranged in an irregular pattern to form a TV wall, and each split screen template is only used for illustration and is not intended to limit the present invention.

[0027] Figure 2 The split screen template shown is used to standardize how multiple display devices 30 are arranged to form TV walls of different shapes. For example, when multiple display devices 30 are actually arranged into a TV wall, the operation interface 111 can select a split screen template that matches the current arrangement shape of the TV wall, and can further set the display position and display area size of the display screen of the first image signal or the second image signal in this split screen template. Display configuration settings, and after these operations and settings, a corresponding screen setting signal can be generated for execution by the processing circuit 101.

[0028] In one embodiment, Figure 2 Each split screen template in the template selection menu screen 5 can be preset, and if the TV wall formed by the actual arrangement of multiple display devices 30 is not Figure 2 When the split screen templates in the image processing circuit 101 are selected, other split screen templates with different arrangement shapes can be expanded through the setting circuit 113. For example, the setting circuit 113 is electrically connected to the processing circuit 101 and the screen display circuit 109. The setting circuit 113 can set the screen display circuit 109 to display a template setting selection menu, and the operation interface 111 can edit the arrangement positions of these display devices 30 through the template setting selection menu to form a new split screen template, so that it can be selected and used in the template selection menu screen 5 later.

[0029] It is worth noting that when the processing circuit 101 obtains this screen setting signal through the relevant operations and settings of the operation interface 111, the processing circuit 101 can control the screen allocation circuit 107 to output the first image signal or the second image signal to these display devices 30 for corresponding screen allocation according to the split screen template and display configuration settings selected in the screen setting signal, and make the integrated screen displayed by these display devices 30 in combination conform to the display configuration settings of the selected split screen template.

[0030] It should be noted that the source of the integrated screen displayed by the above-mentioned multiple display devices 30 can be the first image signal or the second image signal. For example, when the switching circuit 103 switches the input device 40 to the first computer host 21 to receive the input signal, the image source of the integrated screen is the first image signal, or when the switching circuit 103 switches the input device 40 to the second computer host 22 to receive the input signal, the image source of the integrated screen is the second image signal. In addition, assuming that the image source of the integrated screen is the first image signal, the integrated screen can display the complete or partial display screen of the first image signal according to the screen setting signal.

[0031] In addition, the processing circuit 101 can receive not only the screen setting signal but also the picture-in-picture setting signal. For example, when the operation interface 111 controls the screen display circuit 109 to output and display a template selection menu screen 5, it is possible to further set which of the first image signal and the second image signal is used as the mother screen and the child screen. For example, when the switching circuit 103 switches to select the first computer host 21 to output and display the first image signal, the first image signal can be used as the mother screen and the second image signal can be used as the child screen. Alternatively, when the switching circuit 103 switches to select the second computer host 21 to output and display the second image signal, the second image signal can be used as the mother screen and the first image signal can be used as the child screen. Then, the display configuration settings of the display position and display area size of the mother screen and the child screen displayed on this split screen template can be set respectively. After these operations and settings, the picture-in-picture setting signal can be generated accordingly for the processing circuit 101 to execute.

[0032] It should be noted that the size of the main screen is larger than the sub-screen, and the sub-screen is only displayable by part of the display devices 30 , that is, the display size of the sub-screen is smaller than the integrated screen displayed by multiple display devices 30 .

[0033] In one embodiment, the above-mentioned picture setting signal and picture-in-picture setting signal may be generated by input operation setting of the operation interface 111, and the processing circuit 101 may also receive the picture setting signal and picture-in-picture setting signal provided by other external remote devices through the network interface 115. The network interface 115 is, for example, a wired communication circuit or a wireless communication circuit.

[0034] In one embodiment, the operation interface 111 may be, for example, any combination of buttons and a touch panel, and the processing circuit 101, the setting circuit 113, the screen allocation circuit 107, and the screen display circuit 109 may be, for example, one or any combination of an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), or a system on a chip (SOC), respectively, but the present invention is not limited thereto.

[0035] Next, various display modes of the multi-computer switching device 1 are described by way of example, and it is assumed that the switching circuit 103 switches and selects the first computer host 21 to receive an input signal and output a first image signal to the display device 30 for display.

[0036] Please refer to Figure 3A , Figure 3A A schematic diagram of a multi-computer switching device supporting image segmentation showing a complete image on a regularly arranged TV wall is provided for an embodiment of the present invention. Here, the number of display devices 30 is 4, and the multiple display devices 30 are arranged in a regular 2*2 pattern to form a TV wall T1. Therefore, the personnel can first select the arrangement mode corresponding to the current multiple display devices 30 from the template selection menu screen 5 through the input operation of the operation interface 111 in the multi-computer switching device 1, that is, select the first split screen template 51. Then, the display configuration setting of the display position and display area size of the display screen P1 of the first image signal displayed on this first split screen template 51 is set. Here, the display screen P1 of the first image signal is set to be completely displayed on the integrated screen displayed by the combination of multiple display devices 30.

[0037] After the image setting signal is generated through these settings, the processing circuit 101 in the multi-computer switching device 1 controls the image distribution circuit 107 according to the image setting signal. The image distribution circuit 107 can divide the display image P1 of the first image signal into each display device 30, so that each display device 30 only displays a part of the image in the first image signal. Finally, multiple display devices 30 are arranged into a TV wall T1, which can be combined to display as follows: Figure 3A In addition, Figure 3A The integrated picture shown is a display picture P1 that completely displays the first image signal in full screen.

[0038] Please refer to Figure 3B , Figure 3B A schematic diagram of a multi-computer switching device supporting image segmentation showing a picture-by-picture screen on a regularly arranged TV wall is provided in accordance with an embodiment of the present invention. Here, the number of display devices 30 is 4, and the multiple display devices 30 are arranged in a regular 2*2 pattern to form a TV wall T1. Therefore, the personnel can first select the arrangement mode corresponding to the current multiple display devices 30 from the template selection menu screen 5 through the input operation of the operation interface 111 of the multi-computer switching device 1, that is, select the first split screen template 51. Then, the display position and display area size of the display screen P1 of the first image signal (here as the master screen) and the display screen P2 of the second image signal (here as the sub-screen) displayed on this first split screen template 51 are set. Here, the master screen is set to be fully displayed on the integrated screen displayed by the combination of multiple display devices 30, and the sub-screen is set to be displayed on the partial integrated screen displayed by the combination of multiple display devices 30.

[0039] Finally, after these settings are completed and a picture-in-picture setting signal is generated, the processing circuit 101 in the multi-computer switching device 1 controls the picture allocation circuit 107 according to the picture-in-picture setting signal. The picture allocation circuit 107 can divide the display picture P1 of the first image signal into each display device 30 and divide the display picture P2 of the second image signal into some display devices 30, so that each display device 30 only displays a part of the picture in the first image signal, and some display devices 30 display a part of the picture in the second image signal or a complete picture. Finally, a plurality of display devices 30 are arranged into a TV wall T1, which can be combined to display as follows: Figure 3B In addition, Figure 3B The integrated screen shown is a display screen P1 that completely displays the first image signal in full screen mode, and a display screen P2 that displays the second image signal via a portion of the display device 30 .

[0040] Please refer to Figure 3C , Figure 3C A schematic diagram of a multi-computer switching device supporting image segmentation displaying partial images on a regularly arranged TV wall is provided in accordance with an embodiment of the present invention. Figure 3C Compared to Figure 3A The biggest difference is whether the display screen P1 of the first display signal is completely displayed by multiple display devices 30, and the other related operation settings are the same. Figure 3A I will not go into details here. Figure 3C For example, after the multi-computer switching device 1 receives the screen setting signal, the processing circuit 101 in the multi-computer switching device 1 controls the screen allocation circuit 107 according to the screen setting signal. The screen allocation circuit 107 can divide the display screen P1 of the first image signal into each display device 30, so that each display device 30 only displays a part of the screen in the first image signal, that is, a plurality of display devices 30 are arranged into a TV wall T1, and can be combined to display as follows: Figure 3C In addition, Figure 3C The integrated picture shown is a partial display picture P1 of the first image signal displayed in a full-screen manner, that is, a part of the display picture P1 of the first image signal is not displayed by the plurality of display devices 30 .

[0041] Please refer to Figure 4A , Figure 4AA schematic diagram of a multi-computer switching device supporting image segmentation showing a complete image on an irregularly arranged TV wall is provided for an embodiment of the present invention. Here, the number of display devices 30 is 7, and the multiple display devices 30 are arranged irregularly to form a TV wall T2. Therefore, the personnel can first select the arrangement corresponding to the current multiple display devices 30 from the template selection menu screen 5 through the input operation of the operation interface 111 in the multi-computer switching device 1, that is, select the fifth split screen template 55. Then, the display configuration setting of the display position and display area size of the display screen P1 of the first image signal displayed on this fifth split screen template 55 is set. Here, the display screen P1 of the first image signal is set to be completely displayed in a partial display area in the integrated screen displayed by the combination of multiple display devices 30.

[0042] After the screen setting signal is generated through these settings, the processing circuit 101 in the multi-computer switching device 1 controls the screen allocation circuit 107 according to the screen setting signal. The screen allocation circuit 107 can divide the display screen P1 of the first image signal to display it on the corresponding display device 30. The multiple display devices 30 are arranged into a TV wall T2 and can be combined to display as follows: Figure 4A The integrated screen, Figure 4A Only a part of the display area in the integrated picture has a display picture, that is, the display picture P1 of the first image signal is displayed in a part of the display area in the integrated picture.

[0043] Please refer to Figure 4B , Figure 4B A schematic diagram of a multi-computer switching device supporting image segmentation displaying partial images on an irregularly arranged TV wall is provided in an embodiment of the present invention. Figure 4B Compared to Figure 4A The biggest difference is whether the first display signal is completely displayed by the multiple display devices 30, and the other related operation settings are the same as Figure 4A I will not go into details here. Figure 4B For example, after the multi-computer switching device 1 receives the screen setting signal, the processing circuit 101 in the multi-computer switching device 1 controls the screen allocation circuit 107 according to the screen setting signal. The screen allocation circuit 107 can divide the display screen P1 of the first image signal into each display device 30, so that each display device 30 only displays a part of the screen in the first image signal. When multiple display devices 30 are arranged into a TV wall T2, the display can be combined to form a display as follows: Figure 4B The integrated screen, Figure 4B The integrated picture shown is a full-screen display of a portion of the display picture P1 of the first image signal, that is, a portion of the display picture P1 of the first image signal is not displayed by the plurality of display devices 30 .

[0044] Please refer to Figure 4C , Figure 4C A schematic diagram of a multi-computer switching device supporting image segmentation showing a picture-by-picture screen on an irregularly arranged TV wall is provided in accordance with an embodiment of the present invention. In this case, the number of display devices 30 is 7, and the plurality of display devices 30 are arranged irregularly to form a TV wall T2. Therefore, a person may first select an arrangement corresponding to the plurality of display devices 30 at present from the template selection menu screen 5 through an input operation of the operation interface 111 of the multi-computer switching device 1, that is, select the fifth split screen template 55. Then, the display position and display area size of the display screen P1 of the first image signal (here as the master screen) and the display screen P2 of the second image signal (here as the sub-screen) displayed on this fifth split screen template 55 are set. In this case, a part of the master screen is set to be displayed in a part of the display area of ​​the integrated screen displayed by the plurality of display devices 30 in combination, and a sub-screen is set to be displayed in a part of the integrated screen displayed by the plurality of display devices 30 in combination.

[0045] Finally, after these settings are completed and a picture-in-picture setting signal is generated, the processing circuit 101 in the multi-computer switching device 1 controls the picture allocation circuit 107 according to the picture-in-picture setting signal. The picture allocation circuit 107 can divide the display picture P1 of the first image signal into images corresponding to the display device 30 for display and divide the display picture P2 of the second image signal into images to some of the display devices 30, that is, each display device 30 only displays a part of the picture in the first image signal, and some of the display devices 30 display a part of the picture in the second image signal or a complete picture. Finally, multiple display devices 30 are arranged into a TV wall T2, which can be combined to display as follows: Figure 4C The integrated screen, Figure 4C The partial display area in the integrated picture shown is a partial picture in the display picture P1 displaying the first image signal, and a display picture P2 completely displaying the second image signal via a partial display device 30 .

[0046] Above FIG. 3A to FIG. 4C From the various display modes described above, it can be seen that the arrangement direction of the display device 30 and the display direction of the first image signal or the second image signal can be parallel or non-parallel to each other. FIG. 3A to FIG. 3C In the embodiment, the horizontal axis and the vertical axis of the P1 display screen of the first image signal are parallel to the horizontal axis and the vertical axis corresponding to the display device 30, respectively, and FIG. 4A to FIG. 4C In the embodiment, the horizontal axis and the vertical axis of the display screen P1 of the first image signal are not parallel to the horizontal axis and the vertical axis corresponding to the display device 30 .
