Broadcast-Quality Conversion
Io HD features hardware based full 10 bit broadcast quality motion adaptive SD
to HD upconversion, HD to SD downconversion and HD to HD
crossconversion. The quality of the conversion features found in the Io HD is
virtually identical to AJA's award winning KONA 3 and stand-alone converter
products used throughout the video industry. The built-in upconverter uses a
full 10 bit path, fully motion adaptive de-interlacing, and large multi-point
digital interpolators. Downconversion uses large multi-point digital
interpolators, anti-alias filtering and interpolation.
High-quality hardware-based crossconversion provides the capability to
streamline dailies and offer realtime broadcast picture quality. Because these
functions are in the Io HD 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 upconverting from a
standard definition Final Cut Pro project to an HD deliverable.
Stand Alone Mode
While connected to the Mac, Io HD can be configured for a set of parameters
and then disconnected from the Mac for use by itself as a stand-alone converter.
An example would be using the Io HD in Stand Alone Mode as an SD to HD
upconverter.
To use the Io HD in this way, select the Io HD
Stand Alone Mode
from the
Control
tab of the Control Panel application (see Chapter 5,
Control Tab Screen
).
After configuring the Io HD parameters as desired, click the
Burn...
button.
After doing so, there will be a short time to complete the internal process—and
then you may power down and disconnect the Io HD. From this point, the Io
HD is a stand alone converter and will retain the parameters selected when it is
powered back on. The Io HD remains in Stand Alone Mode until it is once
again connected to a Mac via FireWire. Turning it ON and OFF will not take it
out of Stand Alone Mode until is connected again to a Mac via FireWire.
Note:
The AJA Io HD can also be used as a converter device while it is
connected to a host computer if the
Default Video Output
in the
Control
tab of
the Control Panel application is set to
Input Passthrough
.
Software
AJA’s Io HD was codeveloped with Apple for use with Final Cut Studio on Mac
OS X for powerful SD and HD video/audio capture, editing, and video
production—all in a single integrated system. Io HD runs on an AJA-built
driver, similar to the AJA KONA driver, which provides features such as Core
Audio support and very low latency capture and playback.
