Configuration
VITC Transcoding
The VITC (Vertical Interval Time Code) transcoding controls allow you to
convert between Analog VITC and Digital VITC with same-rate signals of
59.94. The input/output choices will depend on what type of video conver-
sion the module is performing (up, down, or cross).
Note VITC transcoding of input rates of 1080p/sf 23.98 are not supported.
The VITC Transcoding has three sections,
Input Status
,
Encode to Output
, and
Output Signal
, similar to the CC transcoding. Each section is described below.
Input Status
The
Input Status
section will report in the
Encoded Input
field any detected
Analog or Digital VITC encoded on the input when the
Encode to Output
control is set for
Auto
. Figure 42 below shows an input status of
Unavailable
.
An example of VITC present on the input is shown in the Transcoding web
page example in
Figure 39 on page 68 . In this case, the input is encoded
with Digital VITC on line 9.
The specifications for the VITC handled by this module is given at the
bottom of the VITC Transcoding section. If no VITC information is encoded
on the input signal, the module will report
Unavailable
as shown in
Figure 42 .

Encode to Output
This VITC information can be encoded to the output by selecting
Auto
,
Digital
VITC
, or
Analog VITC
. An
Input Line
pulldown menu provides the choice of the
input line for VITC detection on a specific line or the default position of
AUTO DETECT Lines 7-19
. The Input Line pulldown choices are shown in
Figure 43 on page 72 .
