Chapter 1: Introduction
Overview
The AJA HD10MD3 is a miniature digital downconverter for converting HD-SDI video to
standard definition SDI and analog component composite video. The HD10MD3 uses a
full 10-bit data path and a multi-point interpolation to produce excellent quality down-
converted video. In addition, the HD10MD3 converts either 23.98/24Hz 1080p23.98sf or
1080p24sf to a 59.94 Hz output video using the standard 3:2 pulldown technique. The
output can be formatted for either 4:3 or 16:9 standard definition monitors. For 4:3
monitors, the output can be formatted for either the Letterbox or Crop modes. Four
channel AES embedded audio is passed to the SDI output. The HD1OMD3 is also dual-
rate in that SD inputs pass to the SDI and analog outputs.
Features
• Broadcast-Quality HD to SD down conversion
• Multi-Standard
•Dual-rateHD-SD/SDIinput
• HD-SDI input: SMPTE 292/296 HD-SDI digital video
• 1080i 50, 59.94, 60 Hz
• 1080psf: 23.98, 24, 25, 29.97, 30
• 1080p: 23.9B, 24, 25, 29.97, 30
• 720p: 50, 59.94, 60 Hz
• HD-SDI outputs: Equalized and buffered copy of input
• SD-SDI output: SMPTE 259 SDI digital video
• Analog outputs: Component or Composite video (10 bit)
• External DIP switch and internal jumper configuration
• Uses universal input +5V power supply AJA model DWP-U-R1 (included)
NOTE: The HD10MD3 automatically switches to PAL anytime the input is 1080i 50, 1080psf 25 or
1080p25. All other frames rates have an NTSC output: 60, 59.94, 30, 29.97, 24 and 23.98.

HD10MD3 Simplified Block Diagram
HD10MD3 I/O Connections
User Controls
The user interface for the HD10MD3 is an 8-switch DIP accessible through a cut-out in the
bottom of the unit, and an internal jumper block accessed by removing the HD10MD3
cover (secured by 4 screws).
Use the jumpers, if necessary, to synchronize 3:2 pulldown, and to configure vertical
blanking or sync.
Then use the DIP switches to configure outputs, pedestal, blanking, cropping, and
graticule.

The exact function of the DIP switch and the jumper settings are described in “Operation”
on page 7.
Installation
Typically, HD10MD3 installation consists of the following:
1. Disconnect +5VDC from the converter.
2. Configure the DIP switches for the desired equipment configuration and video
formats.
3. Connect video equipment to the converter BNCs.
4. Apply power to the converter.

The following table shows the combinations of DIP switch settings required to configure
the three BNCs below the SDI Output BNC.
Internal Jumper
Jumper J8, which can be used to synchronize 3:2 pulldown and to configure vertical
blanking or sync, is located next to the DIP Switch. By default, jumpers are not installed
(OFF). This default setting uses RP188 to synchronize 3:2 pulldown, and follows RP168 to
make the output start of vertical sync line up with input start of vertical sync. To access
the jumper to change these settings, remove the back of the HD10MD3 case by
removing the 4 Phillips screws that secure it.
