6.1 Concept
Viewers are applications running on the display wall with their windows showing different contents such as vid-
eos, video text, Internet pages, or applications on different screens or display walls.
A bitmap may cover the entire content of the viewer window (blanking) or information (text and/or logo) can
overlay the content at specific positions. Up to 4 so-calledIn Display Captions (IDC) can be defined for each
viewer.
While text can be entered freely and as desired, the available bitmaps for the blanking mode and the IDCs are
managed for all viewers in the ServerData\Globals.ini file. Text colors, background colors, and character size
are defined in this file as well.
Every viewer can be launched with individual parameters and in several instances. The mandatory Ident pa-
rameter is used to access and control the respective viewer. The viewer application cannot be launched at all
without a specified Ident parameter! The Ident parameter has to be unique!
Start parameters are either defined in the shortcut or passed via the command line when launching the com-
mand line interface.
The optional Source parameter defines the actual content of the respective viewer window and can be, e.g., a
Web address (Web Viewer), a video source (FRG Viewer), or the name of a client workstation (Cottus Viewer).
The viewer application is started with a gray window if the Source parameter has not been defined.
The parameters applicable to each viewer are listed with the respective viewer descriptions.
As mentioned above, the respective viewer is controlled with the Ident parameter. The properties of an already
launched viewer can be modified using the properties dialog box or the command line interface.
The following functions are supported from within all viewer applications:
Hide/show of viewer window title bar
Hide/show of viewer window status bar
Hide/show of actual viewer window content
Window content overlay with up to 4 informative contents (text and/or logo)
Additional parameters can be controlled depending on the type of viewer.
Settings selected for a viewer are saved in an *.ini file and are applied to the viewer when launched again. Since
these configuration settings are not only viewer-specific but also user-specific, these files are saved in the re-
spective user folder (Windows NT: ….\WinNT\Profile\User Name or. Windows 2000:… \Documents and
Settings\User Name), using the subfolder \Local Settings\Application Data\Apollo).
