I want to output a video signal matching the RS343 spec
out of an Infinite Reality. The Reality Engine used to offer the
following vof which matches RS343 exactly:

VOF 960x802_30i.u:
  Active Line Length: 960 pixels, 30.99 usec.
  Vertical Active Height: 802 lines
  Nominal Line Period (total width): 1180 pixels, 38.10 usec.
  Lines Per Frame: 875 lines
  Pixel Clock: 30.975000 MHz, period = 32.284100
nsec. Horizontal Line Frequency: 26.250 KHz
  Horizontal Sync Duration: 85 pixels, 2.74 usec.
  Horizontal Back Porch Duration: 105 pixels, 3.39 usec.
  Horizontal Front Porch Duration: 30 pixels, 0.97 usec.
  Vertical Front Porch Duration: 3540 pixels, 3.0 lines, 0.11 msec
  Vertical Sync Duration: 3540 pixels, 3.0 lines, 0.11 msec
    Sync Pulse Duration: 530 pixels, 17.11 usec
    Sync Pulse Count: 6
  Vertical Back Porch Duration: 36580 pixels, 31.0 lines, 1.18 msec
  VWALK to ACTIVID duration: 10640 pixels, 9.016949 lines
  Frame Frequency: 30 Hz Interlaced, 2 Fields
  Flags: (None)

Now my big question is, how can I get the exact same thing from an iR since
there is no vof like this?

I used to think that ircombine would enable me to get this but after
looking at the limited set of controls ircombine offers, I'm starting to
have some serious doubts.
