four Mini-connectors on one end and four BNCs on the other end is provided for
connecting equipment to the SDI inputs and outputs.
In Standard mode, KONA 4/3G offers four video outputs altogether:
• 2 SDI outputs that are used for both High- and Standard-definition (SD/HD-
SDI)
• 2 monitor outputs (discussed later), one component analog and one HDMI
1.4a.
Each of the four outputs is independently switchable between HD and SD. For
example, if you are working in HD, you can have simultaneous HD-SDI, SD-SDI,
and HD-component analog output.
SDI inputs and outputs support video and 8-channel embedded 24-bit digital
audio. Use SDI wherever possible for the best quality 10-bit uncompressed video
input, capture, and output. If peripheral equipment has a variety of inputs/
outputs, look to see if it has SDI I/O, and use it wherever possible. Most high-end
professional broadcast equipment supports SDI (VTRs, cameras, media storage
servers, etc.).
HDMI Output
An HDMI mini-connector on the KONA4/3G endplate (full-size HDMI connectors
on the K3G-Box) provides HDMI 1.4 capability, supporting 4K up to 24fps and
UltraHD at up to 60 fps.
NOTE: KONA 3G supports SD and HD over HDMI. KONA 4 supports UltraHD and 4K over
HDMI also supports multi-channel embedded audio (8 channels). HDCP is not
supported on the output.
Analog Monitor Outputs
Both the standard I/O cable and the optional K3G-Box feature two groups of
three BNC connectors each, for input and output of component, composite and
Y/C functions. The signals are labeled on both the cable and K3G-Box connectors.
The analog component output can be switched between SD and HD. KONA 4/3G
features 12-bit component video output for both HD and SD. SD can be switched
to composite and Y/C. (The same three BNC connectors share component and Y/C
functions.) This allows use of an inexpensive analog monitor for both HD and SD
work. You can even use a composite video monitor. For Dual Link HD-SDI output,
HD or SD can be monitored through the component output. Dual Link HD can be
output as 4:4:4 RGB.
Component video signals are generally higher quality than composite, but not as
high-quality as serial digital (SDI).
About RGB
Although RGB is used less in today's video systems, KONA 4/3G supports it for
A/V Monitor output. However, because the KONA 4/3G (and SMPTE SDI's) native
format is YPbPr, AJA recommends using YPbPr when the monitor supports it.
The YPbPr format provides headroom for "superwhite" and "superblack", and
these video levels will be clipped when transcoding to RGB. Also, the RGB/YPbPr
transcoding involves a level translation that results in mathematical round-off
error. RGB can be configured in the Playout setup panel of the specific application
you are using with KONA 4/3G.
