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 in the softkey changing from Line to Count. In the Mode softkey
selections, Line:Field 1, Line:Field 2 and Count:Vertical are used to indicate where the counting
starts. For an interlaced video signal, the counting starts from the rising edge of the first vertical
serration pulse of Field 1 and/or Field 2. For a non-interlaced video signal, the counting starts after
the rising edge of the vertical sync pulse.
