Timecode Screen
The Timecode input:
• Selects the timecode stream read for applications that use it (for example, when the
timecode source is set to “Use control panel setting,” AJA Control Room will read the
selected stream)
• Is used for monitoring the RP-188 timecode embedded in the digital data stream
• Is used for selecting a timecode offset (if required)

Timecode Input Settings
RP-188 Timecode <n>: In RP-188 timecode (SMPTE 12M-2) there can be multiple timecode types in the data
stream. Use this pull-down to select the one you wish to monitor:
• RP188 LTC (Linear timecode)
• RP188 VITC 1 (Vertical Interval timecode)
• RP188 VITC 2
• LTC Port input
The selection will be displayed in the timecode value displayed to the right of the pull-
down.
User Bits: For monitoring a variable framerate (VFR) timecode (such as Varicam), you may wish to
check the User-bits box. If you set this checkbox, KONA will detect and interpret the user-
bits and display them next to the checkbox. You will see the original framerate (30 fps in
the figure below) followed by the adjusted frame padding (two digits reporting
discarded and retained frame padding).
NOTE: SMPTE 12M-2 is the updated name and specification for what was RP-188.
