Chapter 1 – Introduction
Overview
AJA's OG-HA5-4K is an openGear card that provides high-quality conversion
of HDMI v2.0 to 4K SDI with 4 x 3G-SDI outputs. OG-HA5-4K allows conversion
of HDMI video from various sources, including DSLR's, mirrorless cameras,
action cameras, or prosumer 4K video cameras to 4K SDI for use in professional
workflows. The OG-HA5-4K outputs SDI video with the same format and frame
rate as the incoming HDMI video. The OG-HA5-4K also supports both Square
Division and Two Sample Interleave output mapping.
Designed for use in high-density openGear 2RU frames, including AJA’s OG-X-
FR 2RU frame, the OG-HA5-4K is capable of communicating with Ross Video's
DashBoard Control System. DashBoard runs on Windows®, macOS®, and Linux®,
providing convenient, industry-standard configuration, monitoring and control of
the openGear architecture over a PC or local network.
Default Operation
The OG-HA5-4K auto configures to the connected HDMI input. The auto-
configure function identifies the connected input and outputs the equivalent SDI
format.
An SD or HD output signal uses only BNC SDI Out 1, and the remaining BNC
output connectors are inactive by default. However, the DA function accessible
with DashBoard allows replication of the output signal on those extra output
BNCs.
