About This Manual
This manual describes the features of a specific module of the Gecko 8900
Signal Processing System. As part of this module family, it is subject to
Safety and Regulatory Compliance described in the Gecko 8900 Series
frame and power supply documentation (see the Gecko 8900 Frames Instruc-

8990ARC SD Aspect Ratio Converter
Introduction
The 8990ARC converts between standard (4:3) and widescreen (16:9) SD
video formats. Flexible aspect ratio control is provided on the module’s
front panel and through remote control using the 8900 web browser graphical user interface (GUI) and the Newton Control Panel.
The 8990ARC is compact and fits in the 8900 frame which holds up to 10
modules in 2 RU. It supports 270 Mb serial digital video with outputs referenced from the input signal.
Key features include:
• 270 Mb component serial digital input and output,
•Module is hot-swappable,
•Module settings are stored in non-volatile memory,
•Automatic 525/625 line selection based on video input,
• Passes horizontal ancillary data (HANC),
• Passes or blanks vertical interval ancillary data (VANC),
• Standard, modified, and custom Video Index Coding and Wide Screen
Signaling (WSS) with selectable WSS line,
•GPI (general purpose interface) input can recall one of four
user-defined preset settings,
• Selection of top and bottom one, two, or three active video lines as data
lines, and
•Remote control and monitoring through the 8900 frame ethernet I/F
and Newton Control Panel (with 8900NET module running software
version 3.2.0 and later).

Installation
Installation
Frame Capacity
Installation of the 8990ARC module is a process of:
• Placing the module in the selected frame slot, and
•Cabling and terminating signal ports.
The 8990ARC module can be plugged in and removed from an 8900 Series
frame with power on. When power is applied to the module, LED indicators reflect the initialization process (see
The maximum number of 8900 modules allowed in a frame is determined
by frame cooling capacity. Table 1 provides the power capacity, cooling
capacity, and maximum module count for the 8990ARC in each frame type.

on page 12).

Note
Module capacity figures assume no other modules are in the frame.
If the maximum number of modules a frame can handle is less than ten,
provide as much space between the modules as possible.

Module Placement in the 8900 Frame
There are ten cell locations in the frame to accommodate either analog or
digital modules. These are the left ten locations. Refer to Figure 1 on page 9.
The two cells on the right are allocated for the power supplies. For additional information concerning the Power Supply module, refer to the 8900
Power Supply manual.
The third cell from the right is allocated for the Frame Monitor or Network

8900 modules are interchangeable within the module cells. There are 10
BNC connectors in each cell’s I/O group. The functional assignment of
each connector in a group is determined by the module that is placed in
that cell. The maximum number of modules an 8900 frame can accept is ten.

At the back of this manual (hard-copy only) are die-cut overlay cards that can
be placed over the rear connector BNCs to identify the specific 8990ARC connector functions.
Loop-through Input
Connect an input source to one of the loop-through input connectors, J9 or
J10 (see Figure 3). The 8990ARC input accepts SMPTE 259M-C or EBU tech

GPI Control
The GPI control input at BNCs J7 or J8 (not both) on the rear panel is a
Ω
loop-through input to an A/D converter and a 1.21 K
When the module’s GPI function is enabled, the 8990ARC software will
recognize a GPI input voltage level to select one of four stored user-defined
modes. Looping the input to additional modules allows a single GPI signal
to set them all (up to 10 modules).
The GPI input is created by the application of a parallel resistor between
the coax center and common ground that results in a voltage lower than
+5 V to the A/D converter.
The following voltages (all ±0.4 V) will select the GPI register indicated:
• 1.25 V = GPI 1
• 2.08 V = GPI 2
resistor to +5 V.
• 2.92 V = GPI 3
• 3.75 V = GPI 4
The resistors required for these voltages are shown in Figure 4.

Operation Indicator LEDs
The various front LED indicators and configuration switches are illustrated
in Figure 5. Upon power-up, the green PWR LED should light and the
yellow CONF LED should illuminate for the duration of module initialization.
With factory default configuration and a valid input signal connected, the
green PWR LED, and one of the green signal standard LEDs (525 or 625)
should illuminate (refer to Table 2 on page 13 to see the possible operating
indicator combinations).
Video input presence is indicated by the appropriate 525 or 625 LED (indicating a 525-line or 625-line input signal has been detected). The appropriate Mode LED is on.

Configuration
Configuration
The 8990ARC can be configured locally using onboard switches or
remotely using the 8900NET GUI interface or the Newton Control Panel. A
summary of all functions available with each control type along with the
ranges and default values for each parameter is given in Table 8 on page 26.
The configuration of the 8990ARC determines:
•Output aspect ratio (16:9/4:3),
•Display conversion modes: (see
• Bypass (no conversion),
• Pillarbox for 16:9 output or Letterbox for 4:3 output,
• Full Width for 16:9 output or Full Height for 4:3 output,
• 14:9 output,
•High or Low vertical resizing filtering – for vertical black/white or
severe chroma transitions,
• Position of converted outputs on the monitor (Tilt for vertical and Pan
for horizontal positioning),
• Blanking or passing of vertical ancillary data (VANC),
•Number of active video lines selected as data lines (None, 1, 2, or 3),
• Enable one of three Video Index Control modes allowing control from
data within the video input signal,
• Enable one of three Wide Screen Signaling (WSS) Control modes
allowing control from video source data and selection of WSS line (lines
13-27),
• Enable/disable of GPI control,
Output Conversion Modes
on page 17),
• Save/Recall of user-defined configurations for each of four GPI and
one non-GPI controlled memory register, and
•Recall of factory default settings.
Output Format Control Summary
The output format from the module can be resized by selecting an aspect
ratio, a conversion mode, and setting vertical resizing.
Output Aspect Ratio
The output aspect ratio can be selected with the web page, Newton control
panel, local controls, or though the GPI registers as either 16:9 or 4:3.
Figure 6 on page 15 and Figure 7 on page 16 illustrate the output conver-
sions for both 4:3 and 16:9 formats.

Vertical Resizing
The V Process BW control adjusts vertical sizing to correct filter ringing
above and below the edge on video sources with high contrast or chroma
saturated horizontal edges. Select
tical black/white or severe chroma transitions.
Output Conversion Modes
One of four output conversion modes for either 4:3 or 16:9 output aspect
ratio format can be selected with user controls as follows:
• For 4:3 format, 1 = Bypass, 2 = Letterbox, 3 = Full Height, 4 = 14:9, or
• For 16:9 format, 1 = Bypass, 2 = Pillarbox, 3 = Full Width, 4 = 14:9.
Examples of the conversion modes are shown in Figure 6 on page 15 and
Figure 7 on page 16 for both 4:3 and 16:9 formats.
Configuration
to remove ringing in lines with ver-
Low
Control of the desired video output conversion mode can be from four
sources:
•Web page, Newton Control Panel, or local control,
•GPI triggering of pre-programmed registers,
•Video Index Coding data on video input signal, or
•Wide Screen Signaling (WSS) on input signal.
When set for Remote/Local operation (Figure 9 on page 29), the web page,
Newton Control Panel and local control settings are always enabled and
always valid. GPI controls are based on these settings, stored in GPI registers, and triggered by the web page, local controls, or an customer-supplied
external device. Video Index Coding and WSS may or may not be valid
depending on the presence of information on the input signal. The status
of both WSS and Video Index Coding is reported at all times for the input
signal on the Settings web page in read-only form (
page 36).
Table 3 shows the output formatting control options and the resultant
output processing for various input signals and controls enabled.
