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.
