Chapter 4 Modifying Configuration
Configuring the VITC reader
Use the following procedure if you have VITC timecode embedded in the video
signal. If you use LTC timecode exclusively, this procedure does not apply.
To configure VITC reader:
1. In the AppCenter toolbar, select
System | Configuration
, then
Channel
and either the
R1
or
R2
tab.
2. Open the
Video Input
link.
3. Scroll to locate the question “What lines should be used to read VITC timecode?”.
4. Select the VITC reader setting as follows:
• Detect VITC signal automatically — Select this option, then use the sliders or
number entry controls to enter the range of lines you want the system to search
for VITC. Automatic detection works in most cases unless two pairs of VITC
signals are present and possibly interleaved.
• Look for timecode on lines: — Clear the “Detect VITC signal automatically”
option, then use the sliders or number entry controls to specify the line numbers
where the VITC pair can be found. When two pairs of VITC signals are present,
you can use this mode to specify the lines on which to find the matched set.
