uses a full 10-bit path, fully motion adaptive de-interlacing, and large multi-
point digital interpolators. Down-conversion uses large multi-point digital
interpolators, anti-alias filtering and interpolation.
Cross-conversion is high-quality hardware-based, providing capability to
streamline dailies and offers true broadcast picture quality in real time. Because
these functions are in hardware on the card, they are available full time, all
the time—with no CPU load. Such conversions are useful for cost effective
monitoring, making standard definition dubs of an HD project, or upconverting
from a standard definition project to an HD deliverable.
Audio I/O
• 8-channel 24-bit, 48kHz digital AES/EBU audio
• 16 channels of SDI embedded digital audio
KONA 4/3G supports 8-channel 24-bit 48kHz AES audio via BNC connections on
the supplied breakout cable—or with the optional K3G-Box,16-channels of AES
audio.
KONA 4/3G's high-quality input sample-rate conversion on AES inputs eliminates
the need for audio source synchronization. Sample rate converters auto-lock to
any AES input, 32-96kHz, and then convert it to 24-bit 48kHZ audio, locked to
internal KONA 4/3G video. Sample rate conversion is done at very high quality
(over 120db THD).
Signal Timing
• Genlock input with optional looping capability via the K3G- Box (terminated
on the supplied breakout cable)
• LTC (longitudinal timecode) input/output
Cabling
• Standard 2-meter length connection cables including HDMI mini to HDMI
output
UltraHD/4K Mode Capture and Playout
In 4K Mode, KONA 4/3G offers 4K capture and playback in both YCbCr and RGB.
When using a capture application that supports 4K geometry, the KONA 4/3G
maps connectors SDI1 through SDI 4 as inputs for 4K video.
When 4K playout in Quadrant mode is selected, the four SDI connectors are
remapped as outputs for driving the four quadrants of a 4K display. A large
number of 4K formats are supported for this workflow; see the specifications

Internal HD/SD Hardware Downstream Keyer
KONA 4/3G provides a powerful hardware keyer that can place graphic files with
an alpha channel over video in a selectable matte or the contents of the card's
framebuffer from a software application (including AJA TV). Key a bug or text
over picture and avoid what might normally be a lengthy software render. Also,
working with these software applications, you can key video that has an alpha-
channel over video input or a matte. For example, you can load a QuickTime clip
that has an alpha-channel (a flying logo generated in the Animation codec) into
AJA TV and then place it over live video coming into the card and then passing
both on to a VTR for recording or broadcast.
