“Inputs” Button
Pressing the “Inputs” button will result in two things happening:
1. The display will show more detailed information for all the input signals.
2. The signal buttons (e.g. SDI 1, SDI 2, Fiber, HDMI, etc.) now will be illuminated with colors
according to the input signals. The “Inputs” button itself will be illuminated white to indicate
that it is selected. This button status indication will remain unless the “Outputs” button is
pressed.
Detailed Signal Information
To get detailed information for a specific input signal simply press the signal button (e.g. SDI 1)
when in “Inputs” mode. The chosen signal button will be illuminated more brightly than the other
ones to indicate that it is selected.

The detected input standard of the selected input will be shown at the top of the display. The
bottom of the display will list which internal video processor the signal is assigned to (none, Video
Proc 1 and/or Video Proc 2).
Pressing the same signal button repeatedly will toggle between different pages with more
information. The following example will show the information pages for the SDI inputs.
1. Signal Status Overview
Depending on the type of input (i.e. electrical SDI or Fiber) this page will show details
about the input format, available audio, optical input budget or similar.
2. Preview
The display will show a preview image of the selected input that is assigned to one of
the video processors. This feature is only available for the input signal(s) assigned to
one of the processors.
3. Audio Level Meters
The display will show audio level meters of the selected input that is assigned to one
of the video processors. This feature is only available for the input signal(s) assigned
to one of the processors.
(This feature will be available in one of the next version)
4. Meta Data Information
The display will show the detected meta data information of the selected input that is
assigned to one of the video processors. This feature is only available for the input
signal(s) assigned to one of the processors.
“Outputs” Button
The “Outputs” button works exactly the same way as the “Inputs” button with the difference being
that the monitoring is based on the output signals instead of the input signals.
- The display will show an overview of all the output signals after pressing the
“Outputs” button.
- The signal buttons (e.g. SDI 1, SDI 2, Fiber, HDMI, etc.) will be illuminated with colors
according to the output signals.
- Pressing a signal button when in output mode will show the Detailed Signal
Information in the same way as in input mode (i.e. pressing the signal button
repeatedly will toggle between different information pages – preview and audio level
meters will be available in one of the next versions).

Processing Configuration
The three buttons to the left of the display as well as the top button on the right of the display
access the four processing configuration menus in the display.
Together with the rotary push encoder and the back button these four configuration menus are all
that is required to configure the processing of the callisto greenMachine.
Processing Configuration Menus
The processing configuration menus are generally grouped as shown in the functional diagram
below (Image 11). Settings that logically can’t be associated to any of these three categories can
be found in the “Misc” menu (e.g. storing/loading presets)
Image 10: Configuration Controls
Image 11: Processing Overview

greenMachine callisto Reference Manual - Rev 1.5
Page 12 of 26
The structure and usage of the configuration menus works as follows.
The areas on the left and right side of the display show the active menu items. Turning the rotary
push encoder will navigate between these different menu items. The inverted menu item (i.e. dark
gray with white text) is the currently selected one. It’s possible that there are more than six menu
items. In this case there will be more pages available. These are indicated by the circles at the
bottom of the center part of the menu. The pale gray circle indicates which page is currently
selected. To change pages, simply continue turning the rotary encoder beyond the last icon (next
page) or the first icon (previous page).
There are two different shapes for the menu items. The square boxes are menus containing at
least one additional menu level. When selected the middle part of the display will show a preview
of what settings and/or menus are available within this menu (Image 13). Pressing the encoder
will enter the selected menu. Pressing the “Back” button below the encoder will return to the lower
menu level.

Feature Description
The greenMachine callisto is a high performance 3G/HD/SD dual channel frame synchronizer
with full embedded and external audio support. For each frame synchronizer channel an optional
high quality Up/Down/Cross converter extension is available. Each converter extension can
convert between the different supported input and output standards in addition to freely cropping
and sizing the video images.
Two electrical 3G/HD/SD SDI inputs and outputs are available on the greenMachine callisto. In
addition to this it has an HDMI input and output as well as an optional fiber in and output.
A Sub-D 25 connector provides 4 audio input and output connections that can be configured for
either analog or digital audio.
Supported SDI I/O Formats
The module has two multi-format serial digital inputs with automatic input detection. The module
will detect the following input standards and configure the input stage automatically for operation
in the connected format. The supported SDI output standards are identical to the input standards.
SDTV Formats
HDTV Formats

As the synchronizer uses a single studio reference input both input signals should be the same
input frequency range (odd or even frame rate) as the reference for normal operation.
The output format frequency (or frame rate) is determined by the connected reference signal and
the output will remain fixed to this reference regardless of the connected input signals.

input frequency range (odd or even frame rate) as the reference for normal operation.
The output format frequency (or frame rate) is determined by the connected reference signal and
the output will remain fixed to this reference regardless of the connected input signals.
Supported Reference Input Formats
The module has a very flexible input reference stage which facilitates the use of either SDTV
analog bi-phase sync (i.e. black burst) or HDTV analog tri-level sync. The reference input is
“cross lock” compatible so an SDTV reference can be used to frequency lock HDTV signals (and
vice versa). The connected reference is auto detected and the synchronizer automatically
configures the outputs to the frame rate of the connected reference signal.

Frame Synchronization
The algorithms used for frame synchronization are extremely robust and very tolerant of poor
input signals. The Synchronizer uses “Flywheel” functionality. This allows the module to recover
from any missing sync pulses on the input signal(s) by predicting where they should be and then
re-inserting them.
If no converters are active, the frame synchronizer passes the video in the connected input
format.
Reference Source
The frame synchronizers can be referenced by the external reference input or either one of the
video processing paths. The reference source is a global setting i.e. both frame synchronizers
use the same reference source and can’t be set individually.
If the reference source is set to external reference and no external reference is connected, the
frame synchronizer is in free run mode.
TRS Error Behavior
In addition to synchronizing the video signal(s) to the reference source the frame synchronizers
can also detect TRS errors of the video signal. The frame synchronizers can individually be
configured to either ignore the TRS error or to freeze on TRS error. The freeze behavior is
determined by the freeze mode setting.
Freeze Mode
The Freeze Mode determines the behavior of the individual frame synchronizers when
set to “Freeze on TRS” and detecting a TRS error on the processed video signal.
Possible selections are:
- Freeze Field 1
Only Field 1 will be frozen and output. This only applies for interlaced standards. For
progressive standards the frame synchronizer will automatically freeze frame.
- Freeze Field 2
Only Field 2 will be frozen and output. This only applies for interlaced standards. For
progressive standards the frame synchronizer will automatically freeze frame.
- Freeze Frame
The frame synchronizer will freeze the frame on TRS error.
- Test Pattern
When detecting a TRS error the frame synchronizer will output a test pattern. The
test pattern is identical to the one selected for the test pattern generator.
This setting is ideal to identify TRS errors on the video signal.
Output if no Input
This setting determines the behavior of the frame synchronizer if the processed video input signal
is lost. Three possible selections are available.
- Freeze (outputs the last frame)
- Black (outputs a black signal)
- Test Pattern (outputs the selected test pattern)
