• 12-bit A-to-D quantization for high quality digital video,
• Adaptive filters for optimal 2D decoding,
• Processing amplifier controls to adjust remote analog feeds (luma,
black level, chroma, and hue),
-
• Error Detection and Handling (EDH) to track signal errors,
• Dual reference inputs for multi-format applications,
• 8900FSS Frame Sync/delay submodule (option) for low cost system
timing,
• Vertical Blanking Interval (VBI and data line) processing,
• Built-in test signal generator,
• Audio delay control signal to drive Grass Valley auto-tracking audio
delay DAs,
• Up to ten 8960DEC decoders in a 2 RU Gecko™ 8900 frame (capacity
varies with frame type), and

Connect an input source to one of the loop-through input connectors, J9 or
J10 (see
Figure 5). The 8960DEC input will accept either NTSC or PAL com-
ponent analog video. Terminate the unused connector into 75 ohm if the
signal is not looped to other equipment.
The 8960DEC has four serial digital video outputs—J1 through J4. J5 is an
AES Audio Delay RS-232 data output conforming to 118AS documentation.
Separate input BNCs are provided for either 525-line (J8) or 625-line (J7)
black burst reference signals. The reference inputs are functional only when
the 8900FSS Frame Sync submodule (option) is present. When the sub
-
module is present the inputs provide internal 75 ohm termination.

Operation Indicator LEDs
The front LED indicators and configuration switches are illustrated in
Figure 6. Upon power-up, the green PWR LED should light and the yellow
CONF LED should illuminate for the duration of module initialization.
Note When a media module is first plugged into a Gecko or GeckoFlex frame, the
8900NET module (if present) may report a momentary fault. This will clear
once the media module has booted up.
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
Ta bl e 2 on page 17 to see the possible operating
indicator combinations).
Video input presence is indicated by the 525 or 625 LED (indicating a
525-line or 625-line input signal has been detected). Line standard must be
set manually, there is no auto detection.

Configuration
The 8960DEC can be configured locally using onboard switches or
remotely using the 8900NET network interface or a networked Newton
Control Panel.
Configuration establishes:
• Input video and line standard,
• Level adjustments of the composite video signal input to the decoder,
• Video processing, including adaptive decoding and picture position,
• Vertical blanking interval parameters such as SAV and VBI filtering and
data line configuration, and
• Optional Frame Sync submodule setup and timing, including H and V
phase adjustments and freeze parameters.
Refer to the following sections for configuration instructions:
• Video Path Processing Overview (page 20)
• Configuration Summary (page 20)
• Onboard Module Configuration (page 23)
• Remote Control and Monitoring (page 26)
8960DEC—Instruction Manual 19
Configuration
Video Path Processing Overview
The 8960DEC provides video processing controls for the decoding process.
How the video data is processed depends on what line the video is on. The
following groups of lines have controls on the 8960DEC:
•All Lines
• Active Picture Lines
• Active Picture and VBI Lines
• VBI Lines
• Data Lines
An important feature of the 8960DEC is the ability to define the start of
active video (SAV). The 8960DEC allows you to define the line number for
SAV then use the unused lines of active video for external data insertion.
The active video lines (SAV1–SAV4) on the 8960DEC that can be defined as
the start of active picture and made available for data insertion in both 525
and 625 modes are given in Table 6 on page 25.
Configuration Summary
The 8960DEC module can be configured using the following controls:
• Onboard module controls consisting of a Function rotary switch with a
first (2nd LED off) and second bank (2nd LED on) of settings and a
paddle switch,
• The remote control and monitoring web page interface, and/or
• An external control panel (not all configuration controls are available).
Using each of these control types is explained in detail in their respective
sections of this manual.
Tab le 4 provides a complete summary of the 8960DEC parameters and a
comparison of the functionality available with each control type along with
the ranges and default values for each parameter. The table is organized to
provide a breakdown of the video path processing adjustments by specific
grouping of line type in the video signal.

The 8960DEC module can be configured locally using the rotary and
paddle switches shown in
the configuration process.
These four components perform the following:
• Function (rotary) switch — This switch is used to access a desired function for configuration. 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 (see Tabl e 5). The alternate bank of functions is
accessed each time the Function switch makes a complete revolution
past zero: While in bank 1, a complete revolution past zero accesses
bank 2; while in bank 2, a complete revolution past zero accesses
bank 1. The 2ND LED indicates which bank is currently being accessed.
Note The Function switch should be kept in the position for the selected mode
(1 through 7) or in position B when not in use to avoid any inadvertent change
in configuration. B is an inactive position.
Configuration
Figure 7. Two LEDs are used to indicate status of
• 2ND (second function) LED – when on, indicates that the rotary switch
is addressing the second bank of functions.
• SW1 (paddle) switch – actuates or selects the desired setting for the
selected function when the switch is held momentarily in either the up
or down position.
• CONF (configuring) LED – when on, indicates the module is initializing or processing configuration information.
• Jumper JP1 can be set to allow or lock out remote control.
Note Function switch position F (Recall) in the First Bank can be used to return
module configuration to the factory default.

Remote Configuration and Monitoring
8960DEC configuration and monitoring can be performed using a web
browser GUI interface or a networked Newton Control Panel when the
8900NET Network Interface module is present in the 8900 frame. Each of
these interfaces is described below.
Note For remote access, make sure the jumper block on the module is set for both
Local and Remote access (Figure 7 on page 23).
8900NET Module Information
Refer to the 8900NET Network Interface Module Instruction Manual for
information on the 8900NET Network Interface module and setting up and
operating the Gecko 8900 frame network.
Note The 8900NET module in the frame must be running software version 3.2.2 or
higher for proper remote and control panel operation. Upgrade software and
instructions for the 8900NET can be downloaded from the Grass Valley web
site.
Newton Control Panel Configuration
A Newton Control Panel (hard or soft version) can be interfaced to the
Gecko 8900 Series frame over the local network. Refer to the documentation
that accompanies the Newton Modular Control System for installation,
configuration, and operation information.
Control panel access offers the following considerations for module configuration and monitoring:
• Ability to separate system level tasks from operation ones, minimizing
the potential for on-air mistakes.
• Ability to group modular products—regardless of their physical locations—into logical groups (channels) that you can easily manipulate
with user-configured knobs.
• Update software for applicable modules and assign frame and panel IP
addresses with the NetConfig Networking application.
• Recommended for real-time control of module configuration parameters, providing the fastest response time.
Note Not all module functions are available with the control panel, such as factory
default recalls. The available control panel controls for the 8960DEC module
are listed in Table 4 on page 21.
An example of the Newton Configurator is shown in Figure 8 on page 27.

Web Browser Interface
The web browser interface provides a graphical representation of module
configuration and monitoring.
Use of the web interface offers the following considerations:
• Provides complete access to all module status and configuration func-
tions, including naming of inputs and outputs, factory parameter and
name default recalls, E-MEM functions, slot configuration, and SNMP
monitoring controls.
• Web access will require some normal network time delays for pro-
cessing of information.
• Configuration parameter changes may require pressing
Enter, upload processing time, and a manual screen refresh to become
effective.
• Web interface recommended for setting up module signal and slot
names, E-MEMS, and reporting status for SNMP and monitoring.
Refer to the Frame Status page shown in Figure 9 on page 28. The 8900
modules can be addressed by clicking either on a specific module icon in
the frame status web page or on a module name or slot number in the link
list on the left.

Service
The 8960DEC 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 ser
-
viced 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 21) 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.
• Check output connections for correct I/O mapping (correct input connector is used for the corresponding channel output).
Refer to Figure 6 for the location of PWR LED and Table 2 on page 17 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.

Functional Description
Analog Input and A/D Conversion
The analog video signal is connected to the high impedance loop-through
input. In the analog section the DC black level is automatically restored to
produce standard D1 output blanking levels. The overall video-gain
adjustment gives a ±3 dB range to compensate for standard input video
levels. Before the 12-bit resolution A/D converter, the signal is lowpass fil
tered to avoid anti-aliasing artifacts.
The input serves as the timing reference for the digital decoding process
and is highly tolerant to low quality and noisy signals. The noise level can
vary from as low as 14 dB S/N (white noise) to noise spikes measuring as
high as 1 V p-p (satellite narrow spike noise).

8960DEC—Instruction Manual 45
Functional Description
Three-line Adaptive Comb Decoder
Synchronizer/Output Driver
The Decoder accepts the 27 MHz oversampled NTSC/PAL composite
video signal and generates the decoded Luma and Chroma signals using
2-D adaptive comb filtering. This technology gives better performance than
standard comb filtering for moving pictures without using external
memory. The output signal complies with digital video standards
CCIR-601 and SMPTE-259 at the 27 MHz output clock frequency. All the
necessary timing and interfacing signals are generated internally and for
the selected incoming signal’s standard.
With the addition of the optional frame synchronizer module, the Data
Switch routes the video through the module and the phasing range
becomes infinite. The frame synchronizer is locked to the selected reference
in the horizontal and vertical domain in 37 ns steps that are overlapped
with a fine phase adjustment. The driver section embeds the EDH data and
delivers four SMPTE-259 standard outputs.
References
If the frame sync submodule is present, independent 525/625 reference
inputs are automatically selected according to last valid video input stan
dard.
Microcontroller
Upon power up, the microcontroller configures the decoder chip and loads
the firmware according to the last stored user adjustments. The user adjust
able parameters are input through a of multi-function rotary and paddle
switch interface with an option to recall factory presets.
Frame Communication
All functions are remote read/write through the frame control interface
(available in Gecko 8900TX/TF/TFN frames). The fault reporting output is
connected to the frame controller through the frame motherboard.

Audio Delay Output
The audio delay output is an RS-232 type (refer to 118AS documentation).
Regulator
The +12V input is stepped down to ±5V using an onboard double-buck
Switch Mode Power Supply (SMPS). The regulator does not start up until
the main supply voltage reaches approximately 80% of its nominal value.

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/FFN
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.
48 8960DEC—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 16. 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 the 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 web page – reports overall frame and module status in
graphical and text formats.
• Module Status web page – shows specific input and reference signal
status to the module along with enabled options and module versions.
• A Sta tus L ED ic on on eac h web page to rep ort co mmun ica tion stat us fo r
the frame slot and acts as a link to the Status web 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. Some module status reporting items
can also be enabled or disabled on individual configuration web pages.
8960DEC—Instruction Manual 49
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 web page for the Frame, the
8900NET module, and each module slot. Refer to the 8900NET Network
Interface Instruction Manual for installation instructions.
