For example, to do a down-conversion on an HD input:
Set the Primary Format as an SD format
Select the correct HD format with an (I) input designation for the Secondary Format, then
Choose a “– Secondary” Video Input type
Down-conversion display mode choices that may be available include:
• Anamorphic: full-screen
• Letterbox: image is reduced with black top and bottom added to image area with the
aspect ratio preserved
• Crop: image is cropped horizontally to fit new screen size
This parameter applies to using the Ki Pro Rack to transfer data.
Video Formats For a complete list of supported video formats, see “Video Formats” on page 52 .
Io XT Audio
Io XT provides up to 16 channels of SDI embedded audio. The front panel has a mini TRS
headphone output with a lockable level control knob.
For analog audio output monitoring, Io XT provides a DB25 connector with eight
channels of audio to be used with industry standard Tascam-style audio breakout cables.
The front panel has an eight-channel VU meter display to monitor output levels.
Dual Link
Io XT supports Dual Link HD-SDI (4:4:4). Io XT supports the ingest and output of SMPTE-
372M compliant 4:4:4 RGB video and high-bandwidth 4:2:2 1080p 50, 1080p 59.94, and
1080p 60 at 10-bit.
Hardware-based
Acceleration
Io XT offers DVCPROHD, HDV, and Apple RT Extreme hardware acceleration. This is how
Io XT accelerates DVCPROHD, HDV, and Apple RT Effects:
A precision hardware scalar in Io XT does what the Apple computer's processor
would otherwise have to do—scaling of less than full-raster HD (DVCProHD and
HDV) to full-raster size. This speeds up the system while scaling at full 10-bit
broadcast quality.
The Io XT advanced scaling engine takes the native frame (long GOP 1440 HD) and
outputs it via hardware-in real time. Precision AJA circuitry re- sizes the video to full-
raster 1920 x 1080, providing instantaneous playback of HDV captured for both
monitoring and recording.
Io XT can provide real time monitoring and playback to both HD and SD monitors and
decks via the realtime hardware scaler and down-converter on board.
