* The VBI slicer starts operating and counting lines, beginning at

* This staring field line, S, is 6 (& 319) or 10 (& 273) for 625 or 525
* line systems respectively. Sliced ancillary data captured on VBI
* slicer line M is inserted after the VBI slicer is done with line M,
* when VBI slicer line count is N = M+1. Thus when the VBI slicer
* reports a VBI slicer line number with ancillary data, the IDID0 byte
* indicates VBI slicer line N. The actual field line that the captured
* data comes from is
*
* L = M+(S+D-1) = N-1+(S+D-1) = N + (S+D-2).
*
* L is the line in the field, not frame, from which the VBI data came.
* N is the line reported by the slicer in the ancillary data.
* D is the slicer_line_delay value programmed into register 0x47f.
* S is 6 for 625 line systems or 10 for 525 line systems
* (S+D-2) is the slicer_line_offset used to convert slicer reported
* line counts to actual field lines.
