1 Introduction to Synapse
An Introduction to
Synapse Synapse is a modular system designed for the broadcast industry.
High density, intuitive operation and high quality processing are
key features of this system. Synapse offers a full range of
converters and processing modules. Please visit the AXON Digital
Design Website at www.axon.tv to obtain the latest information on
our new products and updates.
Local Control Panel The local control panel gives access to all adjustable parameters
and provides status information for any of the cards in the Synapse
frame, including the Synapse rack controller. The local control
panel is also used to back-up and restore card settings. Please refer
to the RRC18, RRC10 and RRC04 manuals for a detailed
description of the local control panel, the way to set-up remote
control over IP and for frame related settings and status
information.
Remote Control
Capabilities The remote control options are explained in the rack controller
(RRC18/RRC10/RRC04) manual. The method of connection to a
computer using Ethernet is described in the RRC manual.
! CHECK-OUT: “SYNAPSE SET-UP” SOFTWARE
WILL INCREASE SYSTEM FLEXIBILITY OF ONE OR
MORE SYNAPSE FRAMES
Although not required to Setup a Synapse frame, you are strongly
advised to use a remote personal computer or laptop PC with the
Synapse Setup software as this increases the ease of use and
understanding of the modules.

2Unpacking and Placement
Unpacking The Axon Synapse card must be unpacked in an anti-static
environment. Care must be taken NOT to touch components on the
card – always handle the card carefully by the edges. The card
must be stored and shipped in anti-static packaging. Ensuring that
these precautions are followed will prevent premature failure from
components mounted on the board.
Locating the card The Synapse card can be placed vertically in an SFR18 frame or
horizontally in an SFR04 frame. Locate the two guide slots to be
used, slide in the mounted circuit board, and push it firmly to
locate the connectors.
Correct insertion of card is essential as a card that is not located
properly may show valid indicators, but does not function
correctly.
REMARK: On power up all LEDs will light for a few seconds, this
is the time it takes to initialise the card.

5
3A Quick Start
When Powering-up On powering up the Synapse frame, the card set will use basic data
and default initialisation settings. All LEDs will light during this
process. After initialisation, several LEDs will remain lit – the
exact number and configuration is dependant upon the number of
inputs connected and the status of the inputs.
Default settings In its default condition, the ASV12 will act as an 12 bit analog
composite to serial digital converter.
Changing settings
and parameters The front panel controls or the Synapse Set-Up Software can be
used to change settings. An overview of the settings can be found
in chapter 5, 6 and 7 of this manual.

Synapse Setup
Software
Synapse Setup Software can be used to change the settings of
Synapse modules from a PC, either locally or remotely. The
software enables communication based on TCP/IP between the
Setup PC and Synapse frames/modules.
Each Synapse frame is addressed through its rack controller’s
unique IP address, giving access to each module, its menus and
adjustment items. The Synapse Setup software has access to data
contained within the Synapse module and displays it on a GUI.
The software has an intuitive structure following that of the
module that it is controlling.
Having selected the desired Frame and Module from the GUI
Synapse Network View, select the menu item that you wish to
open. Opening the menu item gives a complete list of available
properties with their associated Value.
For example to change a setting e.g. SDI-Format, select SDI-
Format form the list of settings by ‘double clicking’ to open a
dialogue box. The dialogue box allows parameters to be changed
or set to default value. On completion close the dialogue box.

4 The ASV12 Card
Introduction The AXON ASV12 is a 12 bit analog to digital converter that
converts Analog Composite signals to Serial Digital (SDI). The
ASV12 has a Frame Synchronizer, video proc-amp, VI inserter and
an adaptive 5-Line Comb Filter for signal enhancement.
The converter is capable of working with most common television
standards, PAL, NTSC.
All Digital Decoding The ASV12 12-bit digital decoding to ensure accurate high quality
signal processing.
5-Line Adaptive
Comb Filter A 5-line adaptive comb filter is provided that produces a clean
noise free image with minimum artefacts.
Analog Composite
Input The ASV12 has one analog composite input capable of accepting a
range of video standards.
Four Serial Digital
Outputs Four SDI outputs are available with embedded audio, reducing the
need for distribution amplifiers and external embedders.
Automatic Standard
Selection Most video standards can be handled by the ASV12. In ‘Auto’
Mode (see later) the unit automatically detects the input standard
being used and changes the signal processing to the standard
detected at the input.
Audio Embedding When used with optional ADD-On cards, the ASV12 can perform
audio embedding of up to eight channels into the output SDI
stream.
Built-in Framestore In order to allow the ASV12 to handle poor quality input signals
and correct timing errors a frame store is provided.
Reference Input Two reference input are provided to the ASV12 by the Synapse
Bus, these can be the same TV standard in order to provide
redundancy, or different TV standards to allow operation in two
different modes.
External Freeze External Freeze allows the ASV12 to freeze the output signal. This
is performed manually by switching to freeze input.

9
Tracking output A tracking output is provided by the ASV12. This output provides
a timing pulse for use with other Axon Synapse devices, e.g. for
Audio Synchronisation with a DIO24.
Back planes The ASV12 can be used with the BPL01 back plane.
Miscellaneous The ASV12 cards fit into the Axon SFR04 & SFR18 rack.
LED’s on the front of the board indicate the presence Video
Reference, Input signal, Connection & Processor Errors.
The ASV12 can be controlled by Axon Synapse set-up software.

5Settings Menu
Introduction The settings menu displays the current state of each setting within
the ASV12 and enables the item to be changed or adjusted.
Settings can be changed using the front panel of the Synapse
frame (SFR18 or SFR04) or Synapse Setup software.
Please refer to chapter 3 for information on the Synapse front
panel control and Synapse Setup software.
Standard This item controls the detection the input standard. The settings
of Standard are Auto, 625 and 525. The default setting is
Auto which automatically detects the presence of a 625 or 525
signal.
625-Stndrd This item sets the input standard when “standard” is set to 625.
The settings are: PAL-BGHI, or PAL-N. Default is PAL-
BGHI
525-Stndrd This item sets the input standard when “standard” is set to 525.
The settings are: NTSC, or PAL-M. Default is NTSC.
Mode Synchronize and Delay mode can be selected within the
Mode menu. In Synchronize mode, the Autophaser/Line
synchroniser is active. In Delay mode a reference is not required,
the output timing is derived from the input.
The default setting is Synchronize.
Synchronizing Mode:
When Mode is set to Synchronize and the card is locked to a
reference, the card is in synchronizing mode. (NOTE that it is
referred to the output signal so it takes the H-V-delay into
account)
Delay Mode:
When Mode is set to Delay, the card is in Delay Mode. The H-
Delay and V-Delay settings give the delay, addition to the
processing time of the card.
Note: The delay of the card is indicated by the tracking pulse on
the BNC output. This can be used, for example, to track an audio
delay.
Input-Gain The input gain can be set to Fixed, Auto-Brst, Auto-Sync

11
or Variable. The default setting is Fixed. In Fixed mode
the input stage is static and expects a compliant input signal with
the correct amplitude. In Auto-Brst an Automatic Gain Control is
enabled, and the gain is based on the color subcarrier’s amplitude.
In Auto-Sync mode an AGC stage is enabled and the input
voltage is adjusted automatically depending on the sync
amplitude. If the sync is smaller then 300 mV, the video input
signal will be amplified in the exact amount to give 300 mV sync
amplitude. If the sync amplitude is too high, the opposite will
occur. And in Variable mode the input signal is manually
adjustable.
Var-Gain This is the adjustment menu for the Variable mode mentioned
above. The range of adjustment is 0,26x to 1,99x. The
default setting is 1,00x.
Ref-Input This setting allows the user to determine which reference input is
used to lock the ASV12. Input 1 is the uppermost input of on the
RRC18 rack controller connection panel at the rear of the SFR18,
Input 2 is the lower. The SFR04 has one reference input.
The available settings for Ref-Input are 1, 2 and Auto. The
default setting of Ref-Input is 1.
1, 2: Lock to the reference at the respective input.
Auto: Selects Ref_1 to 625, Ref_2 to 525. If a signal is not
connected the reference the reference will automatically be
locked to the reference.
H-Delay The H-Delay setting allows adjustment of the horizontal phase
of the output signal with respect to the selected reference input.
The H-Delay setting gives a delay in addition to the reference
timing. For example, if H-Delay is set to 10 samples, the output
signal will be delayed by the reference timing + 10 samples of
37ns, therefore the delay = Ref timing+ 37ns x10. The signal is
delayed (advanced) with respect to the phase of the reference
signal.
In 625/50 the adjustment range of H-Delay is 0-1727 samples,
0..64 µs (one PAL TV line).
In 525/60 the adjustment range of H-Delay is 0-1715 samples,
0...63.556 µs (one NTSC TV line).
The default setting is 0samples.
The Delay of the card in Delay mode is 273 µs.
V-Delay V-Delay setting allows adjustment of the vertical phase of the
output signal with respect to the selected reference input.

12
The V-Delay setting gives a delay in addition to the reference
timing. For example, if V-Delay is set to 10 TV lines, the output
signal will be delayed by the reference timing + 10 TV lines. The
signal is delayed (advanced) with respect to the phase of the
reference signal.
In 625/50 the adjustment range of V-Delay is 0-624 lines (one TV
frame).
In 525/60 the adjustment range is 0-524 lines (one TV frame).
The default setting is 0 lines.
The delay of the card is indicated by the tracking pulse on the
BNC output. This can be used, for example, to track an audio
delay.
VI-sel With this setting you can choose which Vertical Interval you
want to put into the processed signal, or to blanking. Settings are:
CVBS or Blank. Default is CVBS.
Remove-Setup Remove-setup enables setup (Black Level) of NTSC signals
to be removed. The settings of Remove-setup are On and
Off. The default setting is On.
Hue Adjusts the hue. Can be set between -90 dgrs and 90 dgrs.
Chroma-Enhanc The Chroma-Enhanc setting item enables the improvement of
the Chrominance signal being processed by increasing the edge
steepness of the chroma signal. The settings of Chroma-
Enhanc are On and Off. The default setting is Off.
Freeze Freeze enables the capture of one Video Field or Frame
(depending on the setting of Frz-mode) when it is set to On.
Freeze can be set On or Off. The default setting is Off.
Frz-Mode Frz-mode gives the choice of storing a complete Video Frame
or Field (double written) for the above Freeze Menu and the
external freeze input. The settings of Frz-mode are Field
and Frame. The default setting is Field.
Panic Frz Panic-Frz enables the capture of the last video information
when the input signal is lost. Panic freeze always uses Field mode
irrespective of the settings of the Freeze-mode menu item.
The settings of Panic-Frz are On or Off. The default setting

13
is On.
Ext-Frz Ext-Freeze enables the external freeze input. GPI contact
closure J9 of the BPL01. The settings of Ext-Freeze are
Disabled and Enabled. The default setting is Disabled.
Y-Gain Y-Gain controls the Luminance gain of the built-in processing
amplifier. The control range is between 0% and 150%.The default
setting is 100%.
C-Gain Cb-Gain controls the Colour Difference gain of the built-in
processing amplifier. The control range is between 0% and 150%.
The default setting is 100%.
Y-Black This item controls the Luminance black level adjustment between
-128……..+127bits The black level can be aligned by +/–
100mV(analog video). The default setting is 0.
Cb-Black This item controls the Colour Difference (Cb) black level
adjustment.
Cr-Black This item controls the Colour Difference (Cr) black level
adjustment.
EDH-Gen This setting allows the user to switch the built in EDH generator
on/off. The EDH generator inserts EDH (SDI Error Detection
Handling) into the output signal.
The settings of EDH-Gen are On and Off. The default setting is
On.
VLI-Ins The Video Line Index insertion menu enables the generation of
Video Index information. Video Index is used to trigger cascaded
equipment that process wide screen manipulation, aspect ratio
converters for example. VLI-Ins can be set On or Off. The
default setting is Off.
VLI-Data Video Line Index data insertion recognises 16 different modes.
These modes are divided into 2 groups, 4:3 and 16:9, each group
having 8 sub-categories numbered 0-7. Valid VLI-Data ranges
are 4:3_0, 4:3_1, 4:3_2, etc., to 16:9_0, 16:9_1, 16:9_2 etc. The
default setting is 4:3_0.

7Events Menu
Introduction An event is a special message that is generated on the card
asynchronously. This means that it is not the response to a request
to the card, but a spontaneous message.
What is the Goal of
an event? The goal of events is to inform the environment about a changing
condition on the card. A message may be broadcast to mark the
change in status. The message is volatile and cannot be retrieved
from the system after it has been broadcast. There are several
means by which the message can be filtered.
Events The events reported by the ASV12 are as follows;
Announcements Announcements is not an event. This item is only used for
switching the announcement of status changes on/off. 0=off,
other =on
Input Input can be selected between 0 .. 255. 0= no event, 1..255 are the
priority setting. If set to 0no events will be generated. If the input
is lost an Event will be generated at the priority.
Ref-Status Reference can be selected between 0 .. 255. 0= no event, 1..255
are the priority setting. If the reference is lost an Event will be
generated at the priority.
What information is
available in an
event?
The message consists of the following items;
1) A message string to show what has happened in text, for
example: “INP_LOSS”, “REF_LOSS”, “INP_RETURN”.
2) A tag that also shows what happens, but with a predefined
number: e.g. 1 (= loss of input), 2 (= loss of reference), 129(=
1+128 = return of input). For a list of these predefined tags
see the table on the next page.
3) A priority that marks the importance of an event. This value is
defined by the user and can have any value between 1 and
255, or 0 when disabled.
4) A slot number of the source of this event.
