Chapter 1: Introduction
Overview
AJA’s model Hi5-4K converts 4K SDI video inputs to 4K HDMI v1.4a or v2.0b. Additionally,
most SD and HD inputs are supported.
Default Operation
The Hi5-4K auto configures to the connected inputs (no dipswitch settings required). The
auto-configure function identifies the connected inputs and outputs the default or user
configured HDMI output for the given input. AJA’s MiniConfig application is available for
firmware updates and advanced configuration.
NOTE: Signal conversion requires the presence of a valid SDI video signal on the SDI IN 1 BNC.
For single SD or HD inputs, BNC input 1 is the default input. For dual-link 1.5Gb HD
inputs, and 4K dual-stream 3Gb SDI inputs, inputs 1 and 2 are default. Where applicable,
both level A and B 3Gb inputs are auto-detected and supported.
When connecting the Hi5-4K with multiple SDI inputs in the auto-configure mode
(default), as the user connects the first HD-SDI to input 1, the unit will output that input
as a full screen HD. As soon as the second input is connected, the unit will know that
either QuadHD or 4K x 2160 is present and the display will change to show the two
connected quadrants in the upper left and upper right of the 4K output. The remaining
two quadrants will be displayed as they are connected.
It is possible to use two dual stream 3G inputs to make 3840 or 4K video. In this case SDI1
and SDI2 are assumed to be the inputs: SDI1 linkA makes the top left quadrant, SDI1 linkB
makes the top right quadrant, SDI2 linkA makes the lower left quadrant, and SDI2 linkB
makes the lower right quadrant. To use this mode change the Video Source Selection to
'2 X SDI 4K'.
The HI5-4K will output either 4K x2160 or 3840x2160 if more than one HD input is
present and the monitor can support those resolutions. For 4K input the HI5-4K may
provide a center cut 3840, or pass the 4096 to the output, but there is no scaling between
the two.
