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. Note: the Ki Pro LTC output does not provide output during EE
or recording operations; the output is only for use during playback, as might be used
for dubbing content to another device with matching timecode. For timecode to
multiple Ki Pro units, the use of a timecode generator and a timecode distribution
amplifier is recommended.

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.

Pro 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.

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—
for HD material results in an "Invalid Selection" alarm that must be corrected before
recordings or other operations may take place.
