1 Introduction
The ARC102 is a digital aspect ratio converter for 625/525 SDI video.
Two main operational modes are available: preset mode and user mode. In preset mode, 7
factory presets are available. Three presets convert from a 16:9 input video aspect ratio to
a 4:3 output aspect ratio and three presets convert from a 4:3 input video aspect ratio to a
16:9 output aspect ratio. The six factory presets provide a balance between picture loss
and black bars whilst preserving picture geometry. The remaining preset passes the
incoming video unconverted.
The output picture can be cropped in both user and fixed modes. In user mode, the aspect
ratio and the image position is continuously variable. Up to eight user set-ups can be
stored and recalled.
The ARC102 is controllable from board edge, Statesman or from local or remote panels.
GPI selection of both factory and user presets is also provided.
ARC102 Aspect Ratio Converter
The main features are as follows:
•8 bit digital aspect ratio converter
•100mm x 266mm module allows 12 ARC102s in 2U
•6 factory presets and 8 user defined presets
•Continuous horizontal and vertical compression and expansion
•Horizontal and vertical offsets of picture
•Vertical and horizontal cropping
•EDH generation
•GPI selection of presets
•Passes 10 bit embedded audio or data with same delay as picture
•Card edge, active/remote panel and Statesman control options

Crystal Vision Introduction
4
Horizontal and vertical offsets of the picture allow, for example, the easy addition of
subtitles, whilst unlimited vertical and up to 255 horizontal luminance pixel cropping is
provided for cleaning up the edges of the picture and removing unwanted material.
There is automatic 625/525 line standard detection and EDH can be added to the output.
Embedded digital audio and 10-bit ancillary data is passed through unprocessed. There is
a fixed propagation delay of one field between input data and output data.
ARC102 Factory Presets 1-6
The ARC102 is a 100mm x 266mm module, which fits in the three standard frames and
can be integrated with any boards from the company’s full product range. It uses the
RM01 single height rear connector and the RM02 triple height rear connector when used
in a FR2AV or 2U Indigo frame.

2Installing Statesman
The Crystal Vision Statesman PC control software is designed to control a range of
Crystal Vision modules via serial control from a PC. Statesman provides a user friendly
means of configuring and operating the ARC102 with the benefit of see-at-a-glance status
monitoring. Most functions can be accessed from Statesman menus.
The main Statesman application communicates with each module in a frame through an
active control panel. An active panel must be fitted to allow for Statesman control.
Minimum pre-requisites:
•A PC running Windows 98, NT4 with SP 5 or higher Windows 2000 or
Windows XP
•A parallel port dongle supplied with the Statesman software package
•An RS422 serial connection from the host PC to the Remote 2 connector on an
FR1AV or FR2AV Crystal Vision frame with at least one ARC102 module
and/or other Statesman compatible module
•An active control panel MUST be fitted to the frame with version 1.50 or above
firmware
•An optional RS422 to RS232 converter if the PC has no RS422 ports
Installing Statesman
•Refer to the readme and/or help file on the CD before proceeding
•To view all application windows, set graphics resolution to at least 1024 x 768
•Remove any previous version of the Statesman software using the Add/Remove
Programs application in the Windows Control Panel
•Ensure that the Statesman dongle is fitted to the parallel port of the host PC
•Insert the Statesman CD and the installation should start immediately – if it
does not, run the setup.exe file on the CD
•Obey any installation program prompts and restart the PC when prompted
Running Statesman for the first time
The Statesman PC Control System may be run from the Crystal Vision programs folder
via the Start menu or by double-clicking on the Crystal Vision.exe file in the installed
program directory.
When the program runs it will require licence information and an administrator name and
password. It will also need to know which computer port is being used to connect to a
Crystal Vision frame(s).
Note: For further details of Statesman configuration please refer to the Statesman manual.

3 Statesman operation
Once Statesman is configured it should automatically detect any statesman compatible
modules in the connected frame or frames and display them in the main application left
hand explorer-style window.
Open any frame by clicking on the ‘+’ sign or by double clicking on a frame. Installed
modules should be shown with module icons. Frame and module icons can be named as
desired by right-clicking or using the edit menu and choosing rename.
To aid user recognition of module and frame status quickly, the following colour and size
coding is used:
•A module is shown present by full colour and absent by greyed colour
•A module is shown open by large icon size and closed by small icon
•A module is the source of an active alarm if red and not alarmed if green
Double-clicking on a module will enable the display of the main application menus.

Size, position and cropping controls
Size
Click with the mouse in the horizontal size trackball to vary horizontal size by –50% to +
200% giving a possible horizontal expansion of between half and twice original size.
Horizontal size is varied with respect to the left picture edge, only the right edge moves
Click with the mouse in the vertical size trackball to vary vertical size between - 50% and
+ 200% giving a possible vertical expansion of between half and twice original size.
Vertical size is varied with respect to the top picture edge, only the bottom edge moves.
Use the coarse or fine check boxes to vary the control sensitivity. Press the CAL button to
calibrate the horizontal and vertical size and position to 100% with no cropping.
Position
Click with the mouse in the horizontal position trackball to vary horizontal position and
click with the mouse in the vertical position trackball to vary vertical position.
Use the coarse or fine check boxes to vary the control sensitivity. Press the CAL button to
calibrate the horizontal and vertical size and position to 100% with no cropping.
The picture width and height adjustments range from 50% to 200%. The horizontal and
vertical offsets range from –100% to 100%. When the image width and/or height image
size is greater than 100% and the offset is negative, the operator can scan over the input
image. When the image width and height is less than 100% and the offset is positive, the
operator can pan over the input image.
Tip: The position controls are interactive with the size controls and some values are not
permissible. If the position or size controls do not work as expected, try recalling a no
conversion fixed preset as a starting point.
Values may be different in remote mode and local mode and are retained through power
down, and restored when the unit is powered up.

3.2 Fixed conversions and presets
The Presets and Eng tab provides access to fixed conversions.
Fixed Conversion (left pane)
Fixed aspect ratio presets
The No Conversion preset passes the source signal without any conversion.
Letter Box and 16:9 Full Screen presets convert a signal generated by a 16:9 source so
that it can be viewed on a 4:3 monitor with the geometry preserved.
Pillar Box and 4:3 Full Screen presets convert a signal generated by a 4:3 source so that it
can be viewed on a 16:9 monitor with the geometry preserved.

16:9 Letter Box converts the 16:9 source so the full source width is mapped to the 4:3
monitor width. The full source height is compressed to 75% of the output monitor height
to preserve the picture geometry. Horizontal black bands are added to the top and bottom
of the output picture.
16:9 Full Screen converts the 16:9 source so that the central 75% of the source width is
stretched to fit the full 4:3 monitor width. The source height does not need to be
compressed to preserve the picture geometry and no horizontal black bands are added to
the output picture.
14:9 Letter Box converts the 16:9 source so that the central 87.5% of the source width is
stretched to fit the full 4:3 monitor width. The full source height is compressed to 87.5%
of the output monitor height to preserve the picture geometry. Horizontal black bands
added to the top and bottom of the output picture.
