5 AJA Up/Down/Cross Mini-Converter
Introduction
The UDC is a broadcast quality Up/Down/Cross Mini-Converter that can convert
between SD, HD, and 3G 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).
