8960DEC Instruction Manual 7
8960DEC NTSC/PAL to 4:2:2
Adaptive Decoder
Introduction
The 8960DEC module is a low cost, high density decoder for converting
multi-standard composite video signals into a component 4:2:2 serial
digital video signal. Featuring 12-bit A-to-D and full-adaptive decoding,
the 8960DEC provides transition from analog to broadcast quality serial
component digital video. Adding the 8900FSS Frame Sync submodule
option provides a full-frame synchronizer or a frame delay when no refer-
ence signal is present.
The 8960DEC features:
• 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
•Remote control and monitoring using the 8900NET GUI (graphical user
interface) in Gecko 8900TF or TFN frame versions.

8 8960DEC Instruction Manual
Installation
Installation
Installation of the 8960DEC module is a process of:
1.
Placing the module in the proper frame slot, and
2.
Cabling and terminating signal ports.
The 8960DEC module can be plugged in and removed from a Gecko 8900
frame with power on. When power is applied to the module, LED indica-
tors reflect the initialization process (see Power Up on page 11).
Frame Capacity
The 8960DEC module can be installed in all Gecko 8900 frames but with
varying maximum quantities determined by frame cooling capacity.
Table 1 provides the power capacity, cooling capacity, and maximum
module count for each frame type.
Note Module capacity figures assume no other modules are in the frame.
X = Not recommended without forced air cooling.
Module Placement in the Gecko 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 addi-
tional 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
Interface Controller module. These modules provide health monitoring
and control options.

Installation
Figure 1. 8900 Series Frame
8900 module slots are interchangeable within the frame. There are 10 BNC
connectors in each slot’s I/O group. The functional assignment of each con-
nector in a group is determined by the module that is placed in that slot.
The maximum number of modules a Gecko 8900 frame can accept is ten.
Figure 2 illustrates the rear connector plate for a Gecko 8900 frame.
Figure 2. 8900 Series Frame Rear Connector
To install a module in the frame:
1.
Insert the module, connector end first, with the component side of the
module facing to the right and the ejector tab to the top.
2. Verify that the module connector seats properly against the backplane.
3.
Press in the ejector tab to seat the module.

Installation
Cabling
Note At the back of every hardcover manual are overlay cards that can be placed
over the rear connector BNCs to identify the specific 8960DEC connector
functions.
Loop-through Input
Connect an input source to one of the loop-through input connectors, J9 or
J10 (see Figure 3). The 8960DEC input will accept either NTSC or PAL com-
ponent analog video. Terminate the unused connector into 75 Ω if the
signal is not looped to other equipment.
Figure 3. 8960 Input/Output Connectors
Outputs
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.
Reference Inputs
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
Ω termination.

Power Up
The front LED indicators and configuration switches are illustrated in
Figure 4. Upon power-up, the green PWR LED should light and the yellow
CONF LED should illuminate for the duration of module initialization.
Operation Indicator LEDs
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 12 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
Configuration
The 8960DEC can be configured locally using onboard switches or
remotely using the 8900NET network interface or a networked 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 15)
•Configuration Summary (page 15)
•Onboard Module Configuration (page 18)
•Remote Control and Monitoring (page 21)
•Control Panel Configuration (page 31)

8960DEC Instruction Manual 15
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 20.
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.
Table 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.

Onboard Module Configuration
The 8960DEC module can be configured locally using the rotary and
paddle switches shown in Figure 5. Two LEDs are used to indicate status of
the configuration process.
These four components perform the following:
•Function (rotary) switch — This switch is used to access a desired func-
tion 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 Table 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
