Introduction
Features
AJA HD10MD3 HD to SDI Down Converter User Manual — Introduction
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 pulidown 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 SDI inputs pass to the SDI
and analog outputs.

HD10MD3, Side View
The user interface for the HD10MD3 is an 8switch DIP accessible through a cut-out in the
bottom of the unit. Use the DIP switches to
configure outputs, pedestal, blanking, and
enable or disable noise reduction.
The exact function of each DIP switch and
what it controls is described on the following
pages.
