The following parameters can be set on the 2090MDC module:
■
Monitor output display mode,
Pedestal on and off (525 rate only),
■
■
Zoom factor (Zoom mode only),
■
Horizontal position (Full Screen and Zoom mode), and
Control mode – Local/remote or local control only (remote control
■
lockout).
The 2090MDC module provides Letterbox, Amorphous, Full Screen,
and Zoom monitor output modes. Each is explained below and illustrated in Figure 6 on page 8.
Note
In modules with line rate inputs of 525 lines/frame, the pedestal level can
be turned on or off in all four modes.
Letterbox Mode
In Letterbox mode, the whole HD picture is converted to a full SD
picture with horizontal resolution of 720 horizontal pixels and vertical
resolution of 360 (NTSC) or 430 (PAL) lines (per frame).
Amorphous Mode
In Amorphous mode, the whole HD picture is converted to a full SD
picture with horizontal resolution of 720 horizontal pixels and vertical
resolution of 486 (NTSC) or 576 (PAL) lines. No picture information is
lost but vertical stretch occurs causing objects on screen to appear taller.

Configuration
Full Screen Mode
The Full Screen mode provides a monitor output with a complete SD
picture with no distortion. The picture display can be shifted to the left or
right with the on-board paddle switch, or set remotely in the Mode and
Signal Standard display.
The horizontal shift occurs in steps of eight pixels of the input signal. The
maximum number of pixels the display can be moved horizontally differs
in each input standard. The maximum number of pixels that can be shifted
for the three input standards are given in Table 3.
Table 3. Horizontal Shift Values In Full Screen and Zoom Mode
Input Standard Maximum Steps
1080i 60 steps (8 pixels per step)
1035i 68 steps (8 pixels per step)
720p 40 steps (8 pixels per step)
Zoom Mode
The Zoom mode outputs display that can be zoomed in size from letterbox
(minimum) to undistorted full screen (maximum). The display can be
shifted from left to right with the on-board paddle switch or set remotely
in the Mode and Signal Standard display.
In Zoom mode, the maximum number of pixels the display can be moved
horizontally is a function of the input standard (Table 3) and the magnitude
of the zoom. The horizontal shift occurs in steps of eight pixels of the input
signal. At maximum Full Screen zoom factor the maximum number of
pixels can be moved. At minimum Letterbox mode, no horizontal shift is
possible.

Use the FS Horizontal Pos. slider to move the Full Screen display to the left
or right. Use the single (1X) or double arrows (10X), then press the Apply
button.
Note that when using the single arrow, each step change (approximately
eight pixels in either direction) may require up to seven clicks of the single
arrow. This is due to the division of the bar display into 256 steps. Shifting
the display is a function of the maximum number of steps for the input
standard divided by 256.
To determine exactly how many clicks will move the display one step if this
is required, refer to Table 3 on page 9. Make the approximate number of
clicks before pressing the Apply button. The returned bar position will be
an approximate (rounded off) value. The double arrows will increment the
display by approximately 10 times in the same manner.

In Zoom mode (Figure 12), use the Zoom slider to set the zoom factor from
full letterbox (minimum) to full screen (maximum). Use the single (1X) or
double arrows (10X), then press the Apply button.
The Zoom magnitude has 35 possible values. To increment the Zoom by
one step will require up to eight clicks on the single arrow due to the
number of divisions of the bar display. Make the approximate number of
clicks before pressing the Apply button. One double arrow click will increment the Zoom by one step.
Use the Zoom Horizontal Pos. slider to move the display to the left and
right. Use the single (1X) or double arrows (10X), then press the Apply
button. (Note that in minimum full letterbox mode, the horizontal display
is not adjustable.)
Note that when using the single arrow, each step change (approximately
eight pixels in either direction) may require up to seven clicks of the single
arrow. This is due to the division of the bar display into 256 steps. Shifting
the display is a function of the maximum number of steps for the input
standard divided by 256. A larger number of clicks will be required when
the picture has been zoomed down to less than Full Screen size.
Set Zoom factor with
slider (from letterbox
to full screen).
To determine exactly how many clicks will move the display one step if this
is required, refer to Table 3 on page 9. Make the approximate number of

Service
The 2090MDC 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 otherwise directed by Customer Service.
If the module has not passed self-diagnostics, do not attempt to troubleshoot. Return the unit to Grass Valley (see Module Repair).
If your module is not operating correctly, proceed as follows:
■ Check frame and module power. If power is not present, check the fuse
on the front Media module as illustrated in Figure 13.
Module Repair
■ Check for presence and quality of input signals.
■ Verify that source equipment is operating correctly.
■ Check cable connections.

Input Processing
The input section equalizes, re-clocks and de-serializes the HD input
signal.
One equalized and reclocked version of the input is fed back to the rear
looping BNC connector assembly through an output driver to become the
two HD outputs.
Scaler
The parallel video from the input processor is filtered and decimated in the
field/frame buffer in the HD FPGA and enters the scaling engine IC. Video
data from the Input Processing section is scaled down so that it will fit onto
a standard definition screen. The amount and type of scaling is programmed by the user; locally, by setting on-board switches, or remotely
through the frame controller.

UV and Y FIFOs
The UV and Y FIFOs act as buffers between the output of the scaler and the
monitor output section. The FIFOs perform field rate conversion from
60 Hz to 59.94 Hz.
Colorimetry Converter
The colorimetry converter converts the color value from the coding matrix
used for HD video (ITU BT 709) to the corresponding value (ITU BT 601) in
the standard definition coding matrix. This conversion is done in the SD
FPGA.
Multiplexer
The multiplexer section of the SD FPGA multiplexes the Y and UV data into
one D1 data string.
Functional Description
NTSC/RGB Encoder
The D1 signal from the Multiplexer splits off and one path enters the NTSC
Encoder and RGB Converter circuitry. The digital parallel data in D1
format is encoded into analog NTSC and also converted to analog RGB.
These signals are fed through output drivers to the two looping BNCs for
NTSC/PAL video and a set of RGB outputs for feeding component monitors.
Scrambler and Serializer
The other D1 signal path from the Multiplexer enters Scrambler and Serializer circuitry which converts the output into two SDI outputs. These SDI
outputs are sent to an SD driver and then to the rear connector assembly as
the two 601 outputs.
Timing
Each FPGA contains timing circuitry to generate all necessary input and SD
video timing signals needed by the other components. An output pixel
clock is also produced via a phase lock loop locked to the input bit rate.

Microcontroller
The microcontroller configures the other components:
■ At power up,
■ When the standard of the input signal changes, and
■ When the user changes the output display mode using the front panel
pushbuttons or remote control settings.
