Example for the setup of the switcher definition file
The switcher definition file consists of multiple sections. Depending on the described system some sections can
be left out or must be used. Parts that are not used can as well be commented by means of the
/*
and
*/
char-
acters at the beginning, respectively end of the commented part. Twice a slash
//
comments all characters to its
right in the same line.
Here a simple example is given to explain the switcher definition file. It consists of an E
OS
system with two

. They are located in two PCI segments. Two channels of a card are grouped with the
respective channels of the other card to show distributed video. One card displays with the third channel an addi-
tional video window. For this configuration the following sections are used:
•
Grabber

an individual name is assigned.
•
DFRG
One or multiple Grabber get a name as video channel.
•
Sourcelist
All analog sources get a name and their video- / RGB-type gets defined. The sources get combined to
groups, the
Sourcelists .
•
Route
Here it is determined which Sourcelist must be available at which input channels ( Grabber or DFRG ).
•
Cables
This section describes the cabling of each source to the individual inputs of each input card.

we assign the names QAVC-1, QAVC-2, … , QAVC-5 in the five
Grabber sections. The grabber name (here QAVC-x) can be chosen freely unless it does not start with a digit or is
a default name of the system (
frg0
,
frg1

the respective card is written. A
list with the identifiers can be found in Table 6-29. The number of the input is indicated in square brackets.
