![]() There are other software approaches/systems to drive and utilize large video walls.Īll of them present substantially different scopes, goals and higherĬomplexity to the solution presented here. Table 1 recaps each element in the software stack in correspondance with the servers and its accesible hardware functionalities. Realized in the teaching/visualization room. Software, is that all six capabilities from the previous section are The result of combining, VNC, OBS, nginx-rtmp, and other Summary of servers, most relevant components from the software stack and corresponding accessible hardware capabilities. Videowall ( c ) (with 8K full-resolution) USB inputs (wireless mic, wireless keyboard and mouse, …) Videowall ( c ) (with 2K full-resolution) Notice that the AV rack, in addition to provide the hardware infrastructureįor connecting all possible medias, also serves as large multiplexerĪllowing to share some of the different resources among the GPU and PC servers. Diagram of our video wall system, includingĬomputer servers, audiovisual media, as well as software connection using VNC, denoted by dashed lines in the figure. Mobile device, such a tablet or a smartphone ( k ). The second display could therefore even be a portal However, theĬlient (here, the additional laptop) can run an older version of Windows, an Apple device, or anĪndroid device. Operating system (which the Windows server has). Server side: The spacedesk server requires Windows 10 as its To be able to run spacedesk, there are restrictions on the What spacedesk accomplishes is that the client’sĭisplay becomes visible as a second monitor on the Windows Portion runs on the Windows server ( e ), while the spacedesk client runs Setup ( i ), which was connected to the additional display ( j ). In order to achieve this, a Windows laptop was added to the See Figure 2 for a detailed illustration. In addition, the PC server’s screen was visible on the lectureĬonsole, so lecture-style demonstrations were still possible. While the video wall showed the full 8K visualization. Runs the capturing software, enabling a recording of the event The Windows PC also captures the camera input, and On the windows PC that matches the PC’s resolution. A second scaling VNC server (“VNC server2” in Figure 2) Then be used to control the video wall without being tethered to the Microsoft Windows, such as UltraVNC (“VNC server3” in Figure 2). PC server can be driven remotely as well, using a VNC server for Image down to something that a laptop or tabletĬan handle over a typical wireless network. Thus bringing the transfer rate needed to mirror the 8K desktop X11vnc ( x11vnc, ), which is capable of server-side scaling on Linux, The VNC server on the visualization server that we picked for this was
