following analog video outputs.
3 x CVBS (composite) or
1 x YC (S-VHS) + 1 x CVBS (composite) or
1 x YUV or
1 x RGB (for HW Revision 03 only, older boards do not support this)
Two serial digital outputs are also provided which can be configured to provide 2 x digital
down converted outputs or 2 x re-clocked copies of the input signal (1>2 distribution
amplifier)
C DX 5624 Reference Manual. Rev 2.0
Conversion Modes
HDTV Inputs > Down Conversion
With a compatible HD source connected the module only supports down conversion
between divisible frame rates. For example If a frame rate of 59.94Hz is connected to the
input then the module can only output a down converted 59.94Hz output. This module will
not function as standards converter.
Please refer to the table below which shows compatible conversion modes
Input Signal Converted Output Notes
1080i / 50Hz 625 / 50Hz
1080i / 59.94Hz 525 / 59.94Hz
1080i / 60Hz 525 / 59.94Hz 59.94Hz output will drop frame
720P / 50Hz 625 / 50Hz
720P / 59.94Hz 525 / 59.94Hz
720P / 60Hz 525 / 59.94Hz 59.94Hz output will drop frame
Note. It is possible to convert between 60Hz and 59.94Hz. The resulting
cumulative error will result in dropped frames on the converted outputs.
Page 6 of 29
C DX 5624 Reference Manual. Rev 2.0
SDTV Inputs
When a SDTV input is detected the module functions as a D/A converter + distribution
amplifier providing analog and digital outputs of the connected SDTV input signal.
Aspect Ratios
The module supports three aspect ratio conversion modes which can be user selected
using the local controls or preset with the optional control system.
Letterbox
This takes the 16:9 aspect ratio of the input HD signal and fits it into the 4:3 SD aspect
ratio screen with black bars at the top and bottom of the image.
Center Cut
This mode cuts the center portion of the 16:9 input signal and fills the 4:3 SD aspect ratio
screen.
Stretch to Fill
This mode takes the 16:9 input signal and distorts (vertically stretches) the image to fit
the available 4:3 SD aspect ratio space.
Page 7 of 29
C DX 5624 Reference Manual. Rev 2.0
Video Processing
Note. All digital signal processing and D/A conversion is 10 bit.
Video Proc Amp
A basic video proc amp is provided for video adjustments. This provides for adjustable Y
Gain / U Gain / V Gain / Black Level / Sharpness and Hue
Note. Proc amp functions are preset to null. These parameters are adjustable via
the local controls or central control system. Please refer to page 18 for illustrations
of the available GUI controls
Aperture Correction and Color Space Conversion
Adjustable horizontal aperture correction is provided as well as selectable 709 > 601
color space (gamut) conversion. Color space conversion can be set to convert or
transparent modes. In transparent mode the color space is passed from the input to the
output.
Note. Horizontal Aperture correction is factory preset for a flat frequency response
on the SDTV outputs. (The down conversion filtering process results in a slight roll
off in high frequencies). The amount of aperture correction applied is user
adjustable via the local controls or via the central control system. Please refer to
page 18 for illustrations of the available GUI controls.
All module settings are automatically stored in internal flash ram and will survive power
cycles and long term storage.
Note. Settings will be written to flash RAM automatically after 10 seconds with no
activity. This can be observed by the alarm LED flashing yellow three times. If power
is removed before the settings have been stored the module will revert back to the
previous settings when powered up
Audio Processing
The module provides full audio support and will de-embed the complete audio payload
(8xAES) from the incoming SDI signal. This audio is delayed to match the video
processing delay (1 frame) and then re-embedded into the digital down converted
outputs.
Four of the de-embedded AES signals can be selected and output as external digital AES
signals (balanced AES3 signals on the SubD connector). Two additional AES signals can
be selected and output as balanced analog outputs via high quality 24 bit Audio D/A
converters. Full scale ranging, adjustable gain and de-emphasis is provided for each
analog audio output. Balanced analog audio outputs are provided on the integrated 25
pin SubD connector.
DolbyE
If the incoming SDI signal has an encoded DolbyE stream this will be de-embedded,
delayed one frame and re-embedded into the same channels on the down converted SDI
outputs. Providing the Dolby “Guard Band” was timed correctly on the input then the SDI
outputs will have the correct DolbyE audio timing and guard band timing will be
preserved.

Test Patterns
The module contains a selection of video test patterns which can be used for testing and
fault finding. Patterns provided are 75% Colorbars, 75% Colorbars over Red, Full Field
Black, Pathological PLL/EQ and Full field Blue (blue screen). Test patterns are provided
on the analog and Digital video outputs in the selected format. If configured to pass the
input HDTV to the digital outputs then both a Digital HD Test patterns and an Analog
SDTV patterns are provided.
By pre-selecting the input format (with no input connected) the Module can be used as a
stand alone multi-format Test Pattern Generator.

Control System GUI
All LYNX CardModules support a computer interface which allows setting the modules
parameters using a simple GUI interface. Access to all standard features (and in some
cases) extended features is possible using this interface.
Access to the GUI requires the use of the optional LYNX control system
Note. Any settings made using the control system overrides any local settings
made on the module. All settings are stored in internal flash ram and will survive
power cycles and long term storage.
The GUI screenshots below show the settings and adjustments possible for the
C DX 5624 CardModule.
C DX 5624 Reference Manual. Rev 2.0
The above screenshot shows the complete module GUI. The Device info area contains
information about the module including name and firmware revision. If used as part of a
larger system (using the LYNX central control system) the modules position and physical
location is displayed above the “locate” button.
Note. The Locate function us a tool used to quickly identify a module in larger
systems. Selecting “locate” will flash the module alarm LED yellow. (does not
effect module operation)
The first screen you see when the module is selected is the Main tab this is a graphical
representation of the modules function and signal flow (left to right). Clicking on
processing boxes where shown will link to other GUI screens with controls for these
specific functions.
Page 18 of 29
C DX 5624 Reference Manual. Rev 2.0
The area at the bottom of the screen is the error log. Any fault condition will be
timestamps and entered into the log (as long as the controller / adapter is connected)
There are a number of Tabs associated with each Module which splits up the modules
settings into a number of separate screens. The various GUI screens and functions are
described below.
Main Tab
This screen is the main GUI interface and is presented first when the module is displayed
in the GUI. The layout replicates function and the signal flow if from left to right.
Selections are made using onscreen sliders, radio buttons, drop down selections and
checkboxes.
Input Detection
On the left the SDI input is detected and the format displayed on screen (in green)
Deembedder
The first stage is the audio deembedder. The four audio groups are represented by the
dark grey boxes and the individual audio signals within each AES channels are shown as
being present when highlighted green. This is a good reference for checking embedded
audio status on the incoming SD/HDTV SDI stream.
All AES channels (8) are available on an audio crossbar which permits selection of AES
channels for the digital and analog audio output stages. (Selected using the radio
buttons). Each selected AES stream can be individually muted using the checkboxes
provided.
Although not graphically shown, all AES channels (8) are fed through a fixed 1 Frame
delay and embedded back into the down converted digital outputs.
Page 19 of 29
C DX 5624 Reference Manual. Rev 2.0
Test Pattern

• OFF (default)
• Color bars
• Color Bars over Red
• Full field Black
• Pathological PLL/EQ
• Blue Screen
Test Pattern Standard
Using this drop down selection it’s possible to configure the standard of the internal test
signal. This can be preset to follow the last input standard connected or forced into any
independent standard which is useful if using the module as a test pattern source.
Possible standard selections are:
• Follow Last Input (default)
• 525 / 59.94Hz
• 625 / 50 Hz
• 1080i / 59.94Hz
• 1080i / 60Hz
• 1080i / 50Hz
• 720P / 59.94Hz
• 720P / 60Hz
• 720P / 59.94Hz
Down Converter Mode
This drop down selection defines the aspect ratio reproduction for the converted outputs
Selections are
• Center Cut 4:3 (default)
• Letterbox
• Stretch to Fill
Color Space Conversion
This drop down selection configures the color space converter. There are three possiblke
settings
• Bypass (Passes the color space on the input)
• Convert (Performs a 709>601 color space conversion)
• Luma in bypass (Only converts the chrominance portion of the signal)
Page 20 of 29
C DX 5624 Reference Manual. Rev 2.0
Aperture Correction
We provide a horizontal aperture corrector for the converted outputs which permits the
sharpening or softening of the SDTV outputs (a slight roll off in high frequency is a normal
part of the down conversion filtering process). The checkbox can be used to switch
aperture ON and OFF. (ON= Default). When set to ON a small preset amount of
correction is applied to produce a flat frequency response on the outputs. When set to
OFF all Aperture correction is removed.
The amount of aperture correction is adjustable (from the factory preset)
range + 30 to -80. Adjustments in the positive direction will sharpen the image and the
negative direction will soften the image.
SDI output routing
There are two small radio buttons which can be used to change the SDI digital outputs.
One selection takes the signal before the down converter and will provide two re-clocked
outputs of the incoming SDI signal. The other selection (default) provides two converted
digital outputs.
Output Standard
The output standard is indicated in green for the analog and digital outputs.
Note
The down converter will automatically select the correct output standard
depending on the connected input standard. For example if a 50Hz input signal is
