Chapter 1 – Introduction
Overview
AJA’s OG-Hi5-4K-Plus is an openGear card that supports HDMI v2.0 and provides
SDI to HDMI conversion for formats up to 4K/UltraHD and frame rates up to 60
frames per second.
OG-Hi5-4K-Plus provides a simple monitoring connection from professional 4K
devices using Quad 3G-SDI, Quad 1.5G-SDI, or Dual 3G-SDI outputs to displays
with HDMI 2.0 inputs. The HDMI output can be configured for YCbCr 4:2:2, 4:4:4,
4:2:0, or RGB 4:4:4. The unit also supports single link SD, HD, and 3G-SDI inputs.
OG-Hi5-4K-Plus supports Square Division (Quadrant) and Two Sample Interleave
(2SI) input mapping of 4K/UHD signals. It can also generate high dynamic range
(HDR) metadata in accordance with HDMI v2.0a/CTA-861.3.
Designed for use in high-density openGear 2RU frames, including AJA’s OG-X-FR
2RU frame, the OG-Hi5-4K-Plus 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-Hi5-4K-Plus auto configures to the connected inputs. The auto-configure
function identifies the connected inputs, and outputs the default or user
configured HDMI output for the given input.
Ross Video's DashBoard Control System is available for firmware updates and
advanced configuration.
NOTE: Signal conversion requires the presence of a valid SDI video signal on one of the
SDI IN BNC connectors.
For single SD or HD inputs, SDI Input 1 is the default input. For dual-link 1.5G-SDI
inputs, and 4K dual-stream 3G-SDI inputs, SDI Inputs 1 and 2 are the default
inputs. Where applicable, both level A and B 3G-SDI inputs are auto-detected and
supported.
