9.8 Video path setup
By selecting
<VIDEO SETUP>
from the System Configuration page, the video path setup
screens provide the ability to define which DSKs are present in the system, their operating
mode, adding DVEs into the system. In addition the order/ position in which the DSKs, DVE
and FTB functions appear in the programme path can be set, providing the 3428 card is
configured for ‘dynamic’ mode.
9.8.1 Configuring the DSKs
A downstream keyer (DSK) enables images such as captions and logos to be displayed on
top of the programme. The TX 510 can be configured to control up to two DSK cards in the
vision mixer frame. These cards, type 3423, are interchangeable providing the correct line
and fraction settings are made.
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.
9.8.2 DSK operating mode
Selecting
<VIDEO SETUP>
returns the screen to the Video Setup page, where the
<MODE>
key for each keyer toggles its operational mode between caption
<CAPTN>
and
effects
<FX>
. The current status is shown on the screen under the heading ‘Mode’,
alongside the keyer. If the keyer has been removed, the mode is set to N/A, indicating that it
is not available.
