LTC Timecode Input And Output
Two BNCs provide connections to the house LTC timecode generator or
source. Connections are high impedance. One BNC is for input and the
other for output.
SDI Input and Outputs
Two BNC connectors are provided for SDI input and output. SDI input and
output supports SD-SDI and HD-SDI video and embedded 24-bit digital
audio. If your camera has multiple outputs, look to see if it has SDI I/O, and use
it where possible for the highest quality.

Component YPbPr

Connect component YPbPr video cables from a VTR, Camera, or other
source to the three YPbPr input BNCs: Y/G, Pr/R, and Pb/B. Then
connect the YPbPr Out BNCs to a monitor, or other component
device. Component input video signals are A/D (input) converted (10-
bit). Similarly, component output video signals are D/A converted (10-bit). Component
video signals are higher quality than composite.
—Although RGB is used less in today's video systems, Ki Pro
A Note About RGB
supports it at both input and output. Because Ki Pro's (and SMPTE SDI) native
format is YPbPr, AJA recommends the use of YPbPr whenever possible. Although
component video monitors often have RGB inputs, it's better to use YPbPr when
the monitor supports it. The YPbPr format provides "headroom" for "superwhite"
and "superblack"—and these video levels will be clipped when transcoding to RGB.
Also, the RGB/YPbPr transcoding involves a level translation that results in
mathematical round-off error.
