Chapter 1: Introduction
Overview
The UDC is a broadcast quality Up/Down/Cross Mini-Converter that can convert between
SD, HD, and 3G-A video formats. Borrowing from AJA’s industry leading conversion
technology used in our model FS2, the UDC provides very high quality conversions at a
low price. The UDC also supports 16-channel embedded SDI audio. I/Os include SD/HD/
3G SDI Input and Output, HDMI output, and 2-channel RCA-style audio output. The UDC
can be controlled by local DIP switches with additional control available via USB and
AJA’s Mini-Config application. A Reference Input allows the video output to be timed to a
local reference.
Video Formats
The UDC does not convert frame rates—it works with the input frame rate. The only
exception is a 3:2 function where 23.98 is converted to 59.94 (and 24 is converted to 60).
If a reference is provided, it must be in the same frame rate hierarchy as the input video
(e.g., 23.98/29.97/59.94, 25/50, or 24/30/60).
