Output Signal
The VITC on the video output signal can be completely disabled by
selecting the
None
button in the Output Signal section or
Digital VITC
, or
Analog VITC (SD output only)
can be selected. The selection of Digital or Analog
VITC for embedding on the output will depend on what type of conversion
is being performed by the module. Some general rules are listed below:
• The transcoder will only detect analog VITC from SD sources and can
transmit analog VITC into any SD output source.
• When transcoding from 23.98 Hz to 59.94 Hz video VITC data words at
the slow input rate will be repeated in an over-sampling fashion. When
converting in the other direction, some VITC words may be lost, as
expected when sampling them with a slower output frame rate.
An
Output Line
pulldown provides the choice of the line VITC will be on in
the output video signal. Select a specific line or default position of
AUTO
DETECT Lines 7-19
. The Input Line pulldown choices are shown in Figure 44 .
