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 SDM-

874p 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 [email protected] 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 Loop-

Through

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-to-

point 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.

4 Operation

Figure 4 shows the control panel of the SDM-874p, indicating the

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 test 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 markers are disabled.

GUIDE TO INSTALLATION AND OPERATION

6| SDM-874p

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.

On: If time code is detected on the input, it will be burned into

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

will be displayed.

Off: The time code display 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.
