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, 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, Pb/B and Pr/R. 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 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.
—Component Video, or YPbPr, has been given several names
A Note About YPbPr
over time. YUV, Y/R-Y/B-Y, and YCbCr, are just some examples. Although these
various formats have some differences in levels, they are all basically the same. Ki
Pro supports three different types of YPbPr: SMPTE/EBU N10, Betacam (NTSC), and
Betacam (NTSC Japan). These three formats differ in level only.
Note About BETA Setting—Setting the Ki Pro component input and/or output to
"Beta" for HD material will result in an "Invalid Selection" alarm that will need
correction before recordings or other operations may take place.
