Conversion from Video Time Code (D-VITC, ATC) to LTC
Connect a video signal to BNC VIDEO IN. This video signal should have the video time code
embedded.
The XLR male connector LTC OUT outputs the generated LTC, which will be phase aligned to
the video signal, and which contains the data of the video time code with frame-accurate
precision.
As an example, it is shown below how time code conversion can be done in a mixed SD
–
HD
operation. In case of SD video signals, D-VITC will be converted to LTC; in case of HD video
signals, ATC_VITC will be converted to LTC.

Frame Rate
: If the frame rate of the D-VITC
input does not change, please fix it
accordingly (= picture rate of the video
signal, = frame rate of the time code
generator).
Select “

if you are working with
different video formats (NTSC, PAL), in this
case the frame rate of the LTC will be
detected automatically.
