Chapter 1 – Introduction
Overview
The AJA HD10MD4 is a miniature digital downconverter for converting HD-SDI
video to standard definition SDI and analog component or composite video. The
HD10MD4 uses a full 10-bit data path and multi-point interpolation to produce
excellent quality down-converted video. In addition, the HD10MD4 converts
23.98 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. The HD10MD4 can also receive SD video and output a different aspect
ratio. The HD10MD4 simultaneously passes video to both the SDI and analog
outputs. Eight channels of embedded audio channel can also be passed to the
SDI output.
