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.
Placing 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 ASV22 will act as a frame synchroniser
and auto phase corrector.
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.

4 TheASV22 Card
Introduction The AXON ASV22 is a 12bit analog to digital converter that
converts Analog Composite or Y/C signals to Serial Digital (SDI).
In addition the ASV22 has an SDI input.
The converter is capable of working with most common television
standards, PAL, NTSC.
All Digital Decoding The ASV22 utilises 12 bit digital decoding to ensure accurate high
quality signal processing.
Four Serial Digital
Outputs Four SDI ouputs are available with embedded audio, reducing the
need for distribution amplifiers and external embedders.
Composite, Y/C and
SDI Inputs The ASV22 has two analog inputs that can be used for Composite
video or Y/C signals and a separate SDI input. A software switch
allows selection between the inputs. The ASV22 enables the
Active Picture, Vertical Interval and Horizontal Interval
information of the output SDI signal to be selected from separate
input sources.
Automatic Standard
Selection Most video standards can be handled by the ASV22. 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.
Built-in Framestore In order to allow the ASV22 to handle poor quality input signals
and correct timing errors a frame store is provided.
Reference Input Two reference input are provided to the ASV22 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 ASV22 to freeze the output signal. This
is performed manually by switching to freeze input.
Tracking output A tracking output is provided by the ASV22. This output provides
a timing pulse for use with other Axon Synapase devices, e.g. for
Audio Synchronisation with a DIO24.

9
Back planes The ASV22 can be used with the BPL01 back plane.
Miscellaneous The ASV22 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 ASV22 can be controlled by Axon Synapse set-up software.

10
5Settings Menu
Introduction The settings menu displays the current state of each setting within
the ASV22 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.
AP-Sel The ASV22 accepts a range of inputs, SDI, composite (CVBS)
and Y/C signals. AP-Sel selects the Active Picture content from
the selected source.
The settings of AP-Sel are;
CVBS: Composite input with 12bit decoding.
YC: Y/C input with 12bit decoding.
SDI: SDI.
The default setting of AP-Sel is CVBS.
The Active Picture content is combined with Vertical Interval
information and Horizontal Interval information that is set using
the following VI-Sel & HI-Sel settings.
VI-Sel VI-Sel selects the Vertical Interval information to be used by
the ASV22.
Analog: VI information contained within the decoded
Composite input.
SDI: VI information contained within the SDI input signal
Blank: Blanks the VI
The default setting of VI-Sel is Analog.
HI-Sel The HI-Sel settings selects the Horizontal Interval information
to be used. The settings of HI-Sel are;
Blank: Blanks the HI.
SDI: HI information contained within the SDI input signal.
The default setting of HI-Sel is Blank.
REMARK: If the input analog signal does not have information
contained within the Horizontal Interval HI-Sel can only be set
to Blank or SDI.
REMARK: If HI-SEL is set to SDI, the SDI signal has to be
locked to the same reference as the analog active picture input.

11
Standard This item controls the detection the input standard. The settings
of Standard are Auto detection, 625, 525. The default
setting is Auto. Having detected or set a standard, the ASV22
automatically utilises the settings in the menus 625-Stndrd or
525-Stndrd.
625-Stndrd The handling of 625 TV Line standards can be set using 625-
Stndrd. The settings are PAL-BGHI, PAL-N. The default
setting is PAL-BGHI.
525-Stndrd The handling of 525 TV Line standards can be set using this item.
The settings are NTSC, PAL-M. The default setting 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 analog input
signal, if used otherwise timing is derived from the sdi input
signal.
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.

12
Input-Gain The input gain can be set to Fixed, Auto-Brst, Auto-Sync
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 ASV22. 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.

13
Note: Please refer to the following description of Ref input for
synchronization and timing information.
V-Delay V-Delay setting allows adjustment of the vertical phase of the
output signal with respect to the selected reference input.
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.
Note: Please refer to the description of Ref input for
synchronization and timing information.
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.
Chroma-Enh The Chroma-Enh setting item enables the enhancement of the
Chrominance signal being processed in 12bit mode. The settings
of Chroma-Enh are On and Off. The default setting is Off.
Freeze Freeze enables the capture of one Video Frame 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.
