3.8 Controller
The projection units of an O
VER
V
IEW
D Display Wall are provided with display information by the controller. The
controller is available as a standard X-Terminal with exceptional additional properties or as a Windows
NT/2000/XP Workstation.
3.8.1 Controller as X.11 Terminal
The X Window System (also abbreviated to X.11) was originally developed by MIT as a graphic system for UNIX
workstations. In the meantime, it is available on a large number of computer platforms. These also include oper-
ating systems such as VAX/VMS or OS/2 in addition to various UNIX versions.
The X Window System is divided into two parts: The X client and X server are connected to one another by a
communication system (usually TCP/IP). This division permits execution of the X server and X client either on the
same system or also on different systems connected by a network.
The X server is executed on the controller. It implements the graphic display and handles the inputs from the
keyboard and mouse. The X clients can be executed also on the controller or on other systems in the network.
The controller satisfies the X.11 protocol (Rel. 6.), and can thus be used by any X clients, toolkits and window
managers. All X clients (including window managers) use the multi-screen facility without actually 'knowing' this.
Video and RGB Input
The controller has inputs to which video cameras or recorders as well as monitor signals can be connected.
Simple Integration
The controller possesses the generally established interfaces (Ethernet, TCP/IP, X.11 protocol), thus guaranteeing
simple integration into existing computer networks.
Blinking
The controller provides blinking colors (frequencies to DIN).
3.8.2 Controller as Windows NT/ Windows 2000 / Windows XP workstation
If applications based on Microsoft Windows NT or Windows 2000 / Windows XP should be operated via O
VER-
V
IEW
D, the controller as Windows NT/2000/XP Workstation is used. The operating system in this case is Windows
NT 4.0, Windows2000, or Windows XP, so O
VER
V
IEW
D is like a PC with Windows NT/Windows2000/Windows XP
connected to a large monitor. No software modifications are necessary to run applications on O
VER
V
IEW
D.
The Windows applications are operated by keyboard and mouse of the controller.
Video and RGB Input
The controller has inputs to which video cameras or recorders as well as monitor signals can be connected.
