1 SDM-874p SD/HD Serial Digital to DVI Converter

1.1 Introduction

The SDM-874p is a miniature digital video interface, converting
SDI/HDSDI video signals to Digital RGB (DVI-HDTV). It provides
automatic input scan rate detection and supports a wide variety
of input formats, including 525i, 625i, 720p, 1080i and 1080p.
The primary application is to convert SD/HD serial digital video to
Digital RGB to feed DVI-HDTV displays and projectors (CRT,
LCD, Plasma, DLP, D-ILA, etc.). In order to support the
emerging popularity of 24p equipment and displays, the SDM­874p outputs DVI-D with selectable 3:2 sequence insertion. The
SDM-874p is compatible with any 1280x768 or 1920x1200
native resolution display, including the Apple Cinema Display.

2 Overview

Figure 2 illustrates the SDM-874p's major parts and their
locations. A high-definition or standard definition digital video
source is connected to the SDI/HD SDI IN BNC and the Digital
RGB output is provided by the DVI-I connector. Error status is
provided by the status LED. Finally, the power source is
connected to the lockable power connector.

3.1 Power Supply

The LKS-WSU power supply provides power to the SDM-874p
for 110 V and 220 V operation. The power supply is a regulated
+5 VDC@2.4 A power source. The SDM-874p employs a mini
XLR-3 connector for its power needs. Figure 3 shows a detailed
pinout of the male connector.

3.2 HD/SD Serial Digital Video Input & Active Loop­Through

Connect a high-definition or standard definition digital video
signal to the BNC labeled SDI/HD-SDI IN:

• The high-definition serial digital input signal must conform
to the SMPTE 292M standard.

• The standard definition serial digital input signal must
conform to the SMPTE 259M-C standard.

Make sure that the input signal cable has a maximum length of
100m (328’) and that all serial digital video equipment is
connected point-to-point. For instance, there must be a point-to­point connection between the SDI/HD SDI IN BNC and the
source equipment. If a T-connector is used to connect other
equipment, the maximum specified cable length is no longer
valid.

3.3 RGB Output

The high definition DVI video output signal (RGB digital) is
provided by the DVI-I (female) labeled OUTPUT. The output
format is automatically selected according to the input signal
format and the user control settings.

For a complete list of the input and output formats supported by
the SDM-874p, see the Supported Formats table on pages 10 &

11.

five slide switches, the Select pushbutton, and the LED
indicators that show the status established using the Select
pushbutton.

4.1 Slide Switch functions:

Test

On: Enable the te st pattern on the output. The test pattern

consists of HDTV color bars.

Off: The test pattern is disabled.
Note: in order to output a test pattern, a valid input signal must

be present.

Markers 4:3

On: Display 4:3 markers on the 16:9 image.
Off: The 4:3 ma rkers are disabled.

DVI

STD: Video levels are maintained from the SD/HD SDI input

to the DVI output.

EXPD: Video levels from the SD/HD SDI input (16 to 235 in 8

bits) are expanded to the full graphic range (0 to 255 in
8 bits) at the DVI output.

TC

On: If time code is dete cted on the input, it will be burne d into

the output video. If no time code is detected, 00:00:00
will be displayed.

Off: The time code displ ay in the output video will be

disabled.

GFX

1920x1200: Select 1920x1200 as the resolution of the graphic

display output (GFX 60p and GFX 50p). The input
video (SD, 720, 1080) will be mapped into this
image structure.

1280x768: Select 1280x768 as the resolution of the graphic

display output (GFX 60p and GFX 50p). The input
video (SD, 720) will be mapped into this image
structure.

.

4.2 Select Pushbutton functions:

The Select pushbutton cycles the operation of the SDM-874p
through its available operating modes. The current operating
mode is indicated by the six LEDs located to the right of the
pushbutton, as shown in Figure 4. The six named modes are
selected when their LED only is illuminated. Modes A, B and C
are selected when the pair of LEDs indicated are illuminated.

GUIDE TO INSTALLATION AND OPERATION

SDM-874p | 7

• When the pushbutton is pushed once, the LED indicating
the currently selected processing mode flashes red a nd
green. Subsequent pushes cycle the SDM-874p through
the available operating modes.

The available operating modes are:

• Mode A: direct output – the output signal format matches
the input format

• 60i: the output is forced to 60i

• 50i: the output is forced to 50i

• Mode B: reserved for future use

• 60p: the output is forced to 60p

• 50p: the output is forced to 50p

• Mode C: reserved for future use

• GFX 60p: the output is forced to the selected GFX output

resolution (1920x1200 or 1280x768) at 60p.

• GFX 50p: the output is forced to the selected GFX output
resolution (1920x1200 or 1280x768) at 50p.

The SDM-874p automatically detects the input format. It then
internally invokes the appropriate processing to produce the
result selected by the user controls. Among the processing
modes implemented in the SDM-874p are:

• Progressive Segmented Frame (PsF) video takes a
progressive source and divides the image into two fields
as if it had been an interlaced source. This video mimics
the interlaced format and can be processed accordingly.
The SDM-874p converts P→PsF and PsF→ P.

• The Panason i c Varicam system packages video originated
at various frame rates into a standard 59.94i or 60i output
by adding redundant frames. The original frames are
flagged, allowing the original frame-rate signal to be
reconstituted. The SDM-874p supports Varicam output
flagged at 60, 50, 25 and 24 fps.

See the Supported Formats table on pages 10 and 11 for a
detailed list of the outputs corresponding to the supported input
formats and user control settings.

4.3 Status LED

The multi-colored status LED, located between the input and
loop-through connectors, identifies any input errors and the
selection of the test pattern as follows:

Green: Indicates the SDM-874p is powered and has

detected a valid input signal.

Red: Indicates an error in the input signal has been

detected or that there is no input signal installed.

Yellow: The test pattern is selected.

If an error is detected on the input signal when the test pattern is
selected, the status LED will remain red.

Note: in all cases where the format is specified as 24 or 60, the
specification also includes 23.98 and 59.94 when ap propriate.
For example, 1920x1080 60i should be understood to also refer
to 1920x1080 59.94i, and the output will follow the input, so that
an input at 23.98 will yield an output at 59.94, whereas an input
at 24 will yield an output at 60.

As an exception, 525i inputs are always at 59.94, and so the
normal mode outputs have been explicitly specified as 59.94.
However, the GFX outputs are specifically 60 in this case, and
have been so specified.
