8981NR 270 Mb/s SDI Noise Reducer
Introduction
The 8981NR module is a 270 Mb/s SDI component digital noise reducer
module. The module incorporates two different noise reduction methods,
targeted at different sources of noise. A recursive filter is effective for low
levels of wide-band (random) variations that have no frame-to-frame correlation and a horizontal median filter is very effective for impulse noise.
Typical applications include reduction of random noise generated during
analog transmission or digital processing. Signals from various sources
with varying amounts of noise resulting from poor transmission and processing will benefit by the reduction of bandwidth required later during the
MPEG compression process.
The 8981NR features:
• 10-bit signal processing,
•Automatic 525/625 line standard selection based on input,
•Recursion filter for random noise reduction,
•Horizontal median filter for impulse noise reduction,
• Split screen mode with internal noise generator for setup purposes,
•Video processing adjustments including video gain and black level,
• Setting storage in non-volatile memory,
•Output EDH generated,
•VANC pass or blank selection,
• Set blanking width (line 20 or line 21) in 525 mode,
• Passes all HANC data, and
•Remote control lockout jumper disables remote control capability.

Configuration
The 8981NR can be configured locally using onboard switches or remotely
using the 8900NET network interface GUI or a networked control panel.
Refer to the following sections for configuration instructions:
•Configuration Summary (page 13)
• Local Onboard Module Configuration (page 17)
•Remote Control and Monitoring (page 20)
•Control Panel Configuration (page 33)
Operation of these control types is explained in detail in their respective
sections of this manual.
Configuration
Configuration Summary
This section provides a summary of all parameters that can be configured
on the 8981NR module. Table 3 on page 16 provides a summary in table
format of all parameters and their ranges, default values, and remote, local,
and control panel function names and locations for setting each value.
Noise Filter Controls
Noise controls for two different noise reduction methods—recursive and
median— targeted at different sources of noise, are provided on the
module.
Recursive Filter
Recursive filtering is effective for low levels of wide-band (random) noise
that have no frame-to-frame correlation. In this method of filtering, the
input video data is mixed with a portion of the recursive filter output that
is delayed by exactly one frame only if its value is with an adjustable noise
threshold level of that output. The portion amount is set by the recursion
coefficient from none to 100% (an output freeze).
When recursive filtering is enabled, two controls become available:
•Noise Threshold Level – adjustment should be made just slightly
higher than the peak noise level.
•Noise Coefficient – adjustment should be made for minimum acceptable noise suppression.
Both of these adjustments should be set as low as acceptable to minimize
motion blurring artifacts.
8981NR Instruction Manual 13
Configuration
Median Filter
This filtering method acts to replace individual pixels with one of its neighboring pixels in the horizontal direction if it is not with the value range of
the nearest neighboring pixels. This type of filtering is very effective for
single pixel impulse noise where there is no horizontal (line) picture correlation.
The median filter is enabled with an On/Off control. This type of filter has
a larger peak level than the random noise so it occurs before the recursive
filter.
If no impulse noise is present in the signal, it is recommended to leave the
median filter in the Off position, as high frequency horizontal resolution
(sharpness) is reduced with its use.
Other Noise Filter Controls
The following controls are also included with the noise filtering to aid in
making noise adjustments:
Display Bar – when enabled, a sliding horizontal white bar will indicate the
relative value for noise threshold (top) and recursive coefficient (bottom)
on a black background, indicating the full-scale position.
Split Screen – when enabled, allows the output to be split for comparing the
unprocessed video data on the right to the processed video on the left.
Random Noise Generator – when enabled, pseudo-random, wide-band
noise with no average DC value at a peak level of about 8 IRE will be added
to the input. This level is at a practical limit for using recursive filtering and
can be used for experimenting with the noise threshold and recursion coefficient controls. Most actual noise sources will be lower than with this generator and will require lower settings.
Impulse Noise Generator – when enabled, and the random noise generator
is also enabled, positive, single pixel impulse of about 50 IRE are added to
the noise generator output. This control is useful for testing the median
filter.
Note
When the module is powered down, upon restart the Display Bar, Split
Screen, Random Noise Generator, and Impulse Noise Generator will be disabled and must be re-enabled using the local or remote controls.
14 8981NR Instruction Manual
Proc Amp Controls
When the video processor is enabled, the following independent adjustments can be made to the SDI video signal:
•Y, B-Y, and R-Y offset, and
•Y, B-Y, and R-Y gains.
When the Gain Lock control is enabled, all three channels will change gain
by the same amount when any of the channel’s gain settings are adjusted.
When disabled, all processing is bypassed and when re-enabled, the previous settings are in effect.
Vertical Ancillary Line Controls
The module provides controls for blanking all vertical ancillary data (Yes
or No in remote or VANC Pass or VANC Blank in local mode). When
blanking is enabled on all lines, in 525 mode only, the blanking width can
be set to line 20 or line 21 (blank line 21 – Yes or No in remote or set blanking
width to line 20 or line 21 in local mode).
Configuration
All horizontal interval data is passed to the output without processing.
Recall or Save Settings
The current module settings can be saved or recalled into/from one of four
memory registers. All controls, except the test modes, will be stored.

Local Onboard Module Configuration
The 8981NR module can be configured locally using the rotary and paddle
switches. Several LEDs interact with the switches to indicate status of the
configuration process.
Configuration Switches and Controls
Refer to Figure 5 for the following descriptions. Use the onboard configuration components as follows:
• Function (rotary) switch – this switch accesses a desired function for
configuration (see Table 4 on page 19). The switch addresses two banks
of functions; each bank has 16 possible positions (0 through 9 and A
through F). Not all positions are used.
The next bank of functions is accessed each time the Function switch
makes a complete revolution past zero (or back through F): While in
Bank 1, a complete revolution past zero accesses Bank 2; while in Bank
2, a complete revolution past zero accesses Bank 1 again. The yellow
2ND LED indicates which bank is currently being accessed.

turning on and adjusting noise filtering and enabling the display bar and
split screen and the impulse and random noise generators.
Refer to Configuration Summary on page 13 for an overview of each function
and when to use each filtering type. Table 3 on page 16 also gives a
summary of value ranges, step sizes, default values, etc. for each function.
•
•
The following controls can be enabled for use with the noise filters:
Recursive Filter pulldown – turn recursive filtering on or off.
With recursive filtering on, the following recursive noise controls can
be set:
•
Noise Threshold – set the amount of noise threshold in percent.
•
Coefficient – set the noise recursive coefficient.
These controls will be grayed out when the Recursive Filter is off.
Median Filter pulldown – turn median filtering on or off.
•
Display Bar – enables a sliding horizontal white bar to indicate the rela-
tive value for noise threshold (top) and recursive coefficient (bottom)
on a black background.
•
Split Screen – allows the output to be split for comparing the unproc-
essed video data on the right to the processed video on the left.
•
Random Noise Generator – adds a pseudo-random, wide-band noise to the
input. Can be used for experimenting with the noise threshold and
recursion coefficient controls. Most actual noise sources will be lower
than with this generator and will require lower settings.
•
Impulse Noise Generator – adds a positive, single pixel impulse to the noise
generator output. The random noise generator must also be enabled.
Useful for testing the median filter.

Service
The 8981NR modules make extensive use of surface-mount technology and
programmed parts to achieve compact size and adherence to demanding
technical specifications. Circuit modules should not be serviced in the field
unless directed otherwise by Customer Service.
If your module is not operating correctly, proceed as follows:
•Check frame and module power and signal present LEDs.
•Verify power at the voltage testpoints (see Figure 15) and check Fuse F1
if no voltage is detected.
•Check for presence and quality of input signals.
•Verify that source equipment is operating correctly.
•Check cable connections.
Refer to Figure 4 for the location of PWR LED and Table 2 on page 12 for
proper LED indications.
If the module is still not operating correctly, replace it with a known good
spare and return the faulty module to a designated Grass Valley repair
depot. Call your Grass Valley representative for depot location.
Refer to the Contacting Grass Valley at the front of this document for the
Grass Valley Customer Service Information number.

Status Monitoring
Status Monitoring
This section provides a summary of status monitoring and reporting for a
Gecko 8900 Series system. It also summarizes what status items are
reported and how to enable/disable reporting of each item. There are a
number of ways to monitor status of modules, power supplies, fans and
other status items depending on the method of monitoring being used.
8900 Frame status will report the following items:
• Power supply health,
• Status of fans in the frame front cover,
•Temperature,
•Module health, and
• Frame bus status.
Module health status will report the following items:
• Internal module state (and state of submodule or options enabled)
including configuration errors (warning), internal faults, and normal
operation (Pass).
LEDs
• Signal input states including valid/present (pass), not present or
invalid (warning), not monitored, and not available (no signal inputs).
•Reference input states including locked/valid (pass), not
locked/invalid (warning), and not monitored.
• Signal output states with reporting functionality (reference output).
LEDs on modules in the frame and on the front of the 8900TF/TFN frames
indicate status of the frame and the installed power supplies, fans in the
front covers, and modules. (The 8900TX-V/A frames have no LED indicators on the front cover.)
When a red FAULT LED is lit on a frame front cover, the fault will also be
reported on the 8900NET or Frame Monitor module. The LEDs on the front
of these modules can then be read to determine the following fault conditions:
• Power Supply 1 and 2 health,
• Fan rotation status,
• Frame over-temperature condition,
• Frame Bus fault (8900NET only), and
•Module health bus.
36 8981NR Instruction Manual
Frame Alarm
Status Monitoring
In general, LED colors used on the frame and modules indicate:
•Green = normal operation, (Pass) or signal present, module locked.
•Red – On continuously = fault condition, flashing = configuration error.
•Yellow – On continuously = active condition (configuration mode or
communication), flashing in sequence = module locator function.
Status LEDs for this module are described in Operation Indicator LEDs on
page 11. LEDs for the 8900NET module are described in the 8900NET
Network Interface Instruction Manual.
A Frame Alarm connection is available on pins 8 and 9 of the RS-232 connector on the rear of 8900 frame (Frame Monitor or 8900NET Network
Interface module required). This will report any of the status items enabled
with the 8900NET or Frame Monitor module configuration DIP switch.
Connection and use of the Frame Alarm is covered in detail in the 8900NET
Network Interface Instruction Manual.
Web Browser Interface
When the 8900NET module is installed in the frame, a web browser GUI
can indicate frame and module status on the following web pages:
• Frame Status page – reports overall frame and module status in graph-
ical and text formats.
•Module Status page – shows specific input and reference signal status
to the module along with enabled options and module versions.
•A Status LED icon on each web page to report communication status
for the frame slot and acts as a link to the Status page where warnings
and faults are displayed (8900NET version 3.0 or later).
In general, graphics and text colors used indicate the following:
•Green = Pass – signal or reference present, no problems detected.
•Red = Fault – fault condition.
•Yellow = Warning – signal is absent, has errors, or is mis-configured.
•Gray = Not monitored (older 8900 module).
•White = Not present.
Status reporting for the frame is enabled or disabled with the configuration
DIP switches on the 8900NET module. Most module status reporting items
can be enabled or disabled on individual configuration web pages.
8981NR Instruction Manual 37
Status Monitoring
SNMP Reporting
The Gecko 8900 Series system uses the Simple Network Monitoring Protocol (SNMP) internet standard for reporting status information to remote
monitoring stations. When SNMP Agent software is installed on the
8900NET module, enabled status reports are sent to an SNMP Manager
such as the Grass Valley’s NetCentral application.
There are both hardware and software report enable switches for each
report. Both must be enabled for the report to be sent. Software report
switches are set on the 8900NET Configuration page for the Frame, the
8900NET module, and each module slot. Refer to the 8900NET Network
Interface Instruction Manual for installation instructions.
