Features:
The following table provides a comparison of Io 4K and Io XT features.
Broadcast-Quality
Conversion
Io XT 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 Io XT is virtually identical to AJA's
award winning stand-alone converter products used throughout the post production
market. The Io XT 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 and offers true broadcast picture
quality in realtime. Because these functions are in hardware, 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 up-converting from a standard
definition project to an HD deliverable.
