Configuring video
With the switcher definition file user defined names can be assigned to the input, a video switcher can be inte-
grated into the system and be controlled, distributed video can be configured and a video switcher can be used
by multiple computers simultaneously.
Therefore information about the video hardware configuration (i.e. input cards, cabling, switchers, computers,
etc. ) needs to be specified in the switcher definition file and compiled into the registry with the switcher lan-
guage compiler.
If the switcher language compiler is already installed the needed files can be found in the folder:
C:\Program
Files\BARCO\SLC\
or if not installed to the default folder in the folder indicated during the installation process.
Else the switcher language compiler has to be installed, please refer to section
3.5.1 Installing the display driver and
A simple switcher definition file
example.vsw
is included. It can be adapted to your specific configuration and
the name of the file can be changed. The file
slc.exe
is the compiler that reads the indicated switcher definition
file and inserts the entries into the registry. The other files contain static hardware information and may not be
changed.
The switcher definition file
The switcher definition file contains all individual parameters of the related hardware configuration: computers,

. To refer to the different hardware components the hardware identifiers that are listed in the table below are
used. The numbering in square brackets

appended to the hardware identifier distinguishes between multi-
ple hardware instances of the same type. Numbering always starts for all assets except of video switcher sub-
devices with

channel available on the card is numbered, this means for each D

The switcher definition file contains multiple sections with the configuration information:
•
Switcher
Definition of the video switcher hardware, connection settings, number of input and output channels of the
switcher and data format
•
Computer
Definition of the computer by IP address or name. This is required in case of multiple T
