For sources of type Streaming Video the option Last Frame on SignalLos can be selected. In case both options
are checked (Activate on SignalLoss, Last Frame on SignalLos) the blanking image is overlaid the last frame
and – depending on the blanking image – probably nothing of the last frame can be seen…
Select the IdcEnable option to overlay the selected information over the actual viewer window content accord-
ing to settings.
Information can consist of any text, system parameters such as date and time (cf. Placeholders for In Display Caption
Texts), and an image (logo). The available images are defined in the ServerData\Globals.ini file and identical for
all viewers. Colors and font sizes are defined in this file as well.
You can select text color, text background color, size, and position for In Display Caption. Click on the Opaque
option and the text is displayed on the selected color; otherwise, the background is transparent. In case the
Overlap checkbox is ticked, the IDC is displayed within the insertion. Remove the tick to have it displayed out-
side the insertion! Please note that Overlap has no effect in case the IDC is centered!
The logo is always positioned in the corners of the windows followed by the text unless Center is selected. Se-
lecting the Center position always places the logo to the left of the text.
Changes in the text field are not effective unless the Apply button is clicked. All
remaining settings are applied without additional confirmation.
The available IDC positions are as follows:
• Northwest (upper left)
• Northeast (upper right)
• Southwest (lower left)
• Southeast (lower right)
• Center (centered)
• Center North (centered at the top)
• Center South (centered at the bottom)
The Center North and Center South positions overlay a banner, i.e., the IDC covers the entire
width of the viewer window. If a logo is part of this IDC it is displayed in the upper or left or
bottom left corner.
An In Display Caption does not overlay the content of the viewer window until the IDC enable option has been
activated. This option always refers to the currently clicked IDC button.
If several IDCs are activated simultaneously, they are aligned across the content of the viewer window in the
order IDC1, IDC2, IDC3, IDC4. For example, if the position Northwest is selected for all IDCs, then IDC1 is depicted
at the upper left, IDC2 below that, etc.
Title bar (EnabelCaption)and status bar (EnableStatusbar) of the window can be hidden or shown. The title bar
shows the Ident parameter of the viewer. The status bar lists the name or URL of the linked source as well as
information about the downloading progress of the page.
In addition the border of the window can be enabled or disabled. If disabled, the caption is automatically dis-
abled, too.
Without border, no caption can be displayed.
