8.8 Video path setup
By selecting
<VIDEO SETUP>
from the System Configuration page, the video setup
screens provide the ability to define which DSKs are present in the system, their operating
mode, adding DVEs into the system and also setting the order/ position in which the DSKs,
DVE and FTB functions appear in the programme path. This feature only works if the rotary
switch on the 3428 card is set to dynamic control, see Section 5.2.6. However, the position
of the Fade To Black may always be changed.
8.8.1 Configuring the DSKs
A downstream keyer (DSK) enables images such as captions and logos to be displayed on
top of the programme output. The TX 500 can be fitted with up to four DSK cards in the
vision mixer frame. These cards are type 3423 and are interchangeable, providing the
correct line and fraction settings are made. The settings for these cards are detailed in
chapter 5.2.
The operating mode of the downstream keyers is set via the video setup screen. This page
is accessed from the system configuration page by pressing the
<VIDEO SETUP>
button.

important to set the number of keyers available to the system before going on to set the
operating mode for each keyer. This operation depends on the state of the rotary switch on
the 3428 module in the mixer frame, see section 5.2.6.
