Line Number Represents Count
In GENERIC mode, the line number represents the number of a count instead of
a real line number. This is reflected in the label above the softkey changing from
Line to Cnt. In the Trigger On selections, Field 1, Field 2 and Vertical are used to
indicate where the counting starts. For an interlaced TV system, the counting
starts from the rising edge of the first vertical serration pulse of Field 1 and/or
Field 2. For a non-interlaced TV system, the counting starts after the rising edge
of the vertical sync pulse.
