Analog Composite Video Input Time Base Correction
The TBC Selection tab allows you to select Time Base Correction (see Figure
21). When you select Time Base Correction, you can select either composite
input or Super VHS (SVHS or S-video) input. There are two channels available
on this video input board. If Time Base Correction is selected in channel A,
channel B is unselected, and vice versa.
