5.3 SIMULTANEOUS EDITOR- AND LIVE-USE
5.3.1 OPERATIONAL GOAL
A large Electronics-Box (DD 20/30) should be used for two tasks at the same time.
E. g. on one hand it is wished to control a specific module of the E-Box by an Editor,
performing a post production while on the other hand it is wished to run a live show
via one shared E-Box.
5.3.2 NETWORK EXAMPLE
5.3.3 STANDARD SITUATION
In quite a number of installations a DD30 E-Box is used as a server with two panels
connected to it. For instance in an OB-Van (Scanner) a DD20 Panel is used for the
live production, occupying ME2 and PPonly, while simultaneously ME1 is control-
led either via a connected Edit System and an additional DD5 or DD10 panel (see
figure of 5.3.1.2.).
Of course the Editor can currently only be connected to an appropriate E-Box serial
port. The setup for this port has to be done according to the procedures described
in the Operations und Installation Manuals.
In most applications the ”GVG200o” port protocol emulation is the choice.
To get a processed signal at DD’s PGM output and also to be able to use a DSK
and the Fade-To-Black transition the Editor controlled ME1 is automatically selec-
ted as crosspoint on DD’s Preset-Program Bus when no other precautions have
been taken (ME2 by choice).
5.3.4 TECHNICAL BACKGROUND
When emulating a GVG200 on a regular basis, it is evident that editor control for
quite a number of DD-specific operations is omitted since the original GVG switcher
hardware is different.
As a standard application it is assumed that the DD-E-Box is running in a ONE-
OPERATOR-ENVIRONMENT. When applying a GVG command for DSK or FTB
