OG-UDC 3G-SDI Up, Down, Cross-Converter v1.0 4 www.aja.com
Chapter 1 – Introduction
Overview
OG-UDC is an openGear 10-bit broadcast quality up, down, cross-converter that
bridges HD and SD video resolutions. The OG-UDC provides 3G-SDI input and
output, HDMI output and two 3-pin terminal block connectors for analog audio
Outputs. The OG-UDC also supports 16-channel embedded SDI audio.
The OG-UDC can be controlled by local DIP switches with additional control
available via DashBoard Control System with an openGear Frame. A Reference
Input allows the video output to be timed to a local reference.
Designed for use in high-density openGear 2RU frames including AJA’s OG-3-FR
2RU frame, new DashBoard Software support on Windows®, macOS® and Linux®
offers remote control and monitoring of the openGear architecture and provides
convenient and industry standard configuration, monitoring and control options
over a PC or local network.
Video Formats
The OG-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 29.97 (and 24
is converted to 30). 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).
