Conversion: • Broadcast quality hardware-based 10-bit down-conversion
• Broadcast quality hardware based 10-bit up-conversion
• Broadcast quality hardware based 10-bit cross-conversion (1080 to 720 and 720 to
1080)
• Broadcast quality hardware based 10-bit SD aspect ratio conversion (anamorphic to
letterbox, etc.)
KONA 4/3G features hardware-based full 10-bit broadcast quality motion adaptive SD to
HD up-conversion, HD to SD down-conversion and HD to HD cross-conversion. The
quality of the conversion features found in the KONA 4/3G is virtually identical to AJA's
award winning stand-alone converter products used throughout the post production
market. The KONA 4/3G built-in up-converter uses a 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 realtime. 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
UHD/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 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
emerging workflow; see the specifications (
“KONA 4/3G Specifications” on page 85 ) for
supported 4K formats.
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.
