1.1  About Video Display 
1.1.1  What is Video Display? 
The Video Display module is one of the software 
modules designed to be used in conferences and 
discussions using the contribution equipment. 
 
Its function is to interface the software with 
conference video displays. The Video Display 
module provides a means of displaying conference-
related information on video displays located in the 
conference venue. The information can consist of 
text, numbers and graphical elements like bar charts. 
All the information displayed is generated by other 
modules, and it is not possible to alter this 
information in Video Display. 
 
 i 
  Note 
If information is to be displayed on video 
displays, data must be converted within the 
DCN Next Generation control PC or 
transferred to a separate PC via an ethernet 
link. 
 
To use Video Display, it is necessary to have a Video 
Display (VD) Client application. The VD Client 
application receives the information which is passed 
to it from the Video Display (server) module. The 
user can change settings related to how information is 
displayed on the video screens, such as text or 
background colours. This can be carried out either 
during or after installation of the VD Client software. 
 
 i 
  Note 
Video Display information is available via the 
windows Dynamic Data Exchange (DDE) 
protocol. 
A VD Client software is available at the Bosch 
Security Systems Extranet or at your dealer. 
 
 
 
 
 
 
 
 
 
 i 
  Note 
Since Microsoft launched Windows XP service 
pack 2 it is not possible to use DDE in a 
network. To workaround you have to convert 
the DDE locally to another protocol and 
transport this over the network to the PC where 
the VD Client is running. 
The VD Client at Bosch Security Systems 
Extranet does run on a Windows XP service 
pack 2 network. 
 
Video Display is unlike all other modules in that 
there is no user action required to operate it. It 
carries out its function - interfacing the software with 
video displays - automatically. This document is 
therefore not a user manual but a reference manual. 
It gives information on the DDE information which 
is the protocol used to transport the information from 
the Video Display module to the Video Client.
