Using Newton
The Newton modular control system lets you quickly access all of the
Gecko and Kameleon modules in a signal processing path to make audio,
video, and timing adjustments from a single or multiple control points.
As an example of utilizing the Newton control system, an ideal real-time
application would be quality analysis and control of satellite and micro-
wave incoming feeds. As shown in
Figure 5 on page 21 , the incoming sat-
ellite feed to a television station requires video analog-to-digital conversion
with processing and timing adjustments, along with multi-channel audio
processing and delay.
Using the NetConfig application and the Newton Panel Configurator, an
identifying name can be created for the processing channel that includes all
the modules in the path, such as SAT_4. The module icons can then be
dragged and dropped into the Newton Panel Configurator and the desired
parameters assigned to control knobs for the operator to adjust.
The SAT_4 channel in the example may have a number of adjustment
parameters that need to be controlled, such as video gain, black level, hue,
horizontal and vertical timing, audio levels and audio processing functions
such as sum, swap, and phase invert. These controls can be configured then
stored as nested setups which can be accessed when needed by navigating
through them using the Newton control panels.
The Newton control system recalls the current module parameters and dis-
plays them over each of the four control knobs. Each knob takes on the
functionality required for the parameter recalled. Parameters can be contin-
uously variable (such as gain), or enumerated steps (such as an on/off con-
trol.)
Once the configuration of a control panel is complete, it can be saved to
offline storage, edited if required, and loaded to other control panels on the
network. This allows different operators to recall the setups they need for
the required broadcast or edit session.
For increased security, the Newton Panel Configurator allows the engineer
to specify the control available to each panel on the network. Access to a
frame, module, or set of parameters can be controlled.
In addition, with the Router Interface option enabled, simple X-Y control of
a configured router is possible from a panel. A panel can also be used to
follow the source selection from a router for parameter adjustment when
the source is taken to the Monitored Destination defined in Newton config-
uration.
