Comment (by Aleksandr_Slobodeniuk):

 for 720 system it tells:

 {{{
 For the 720-line system (see table 17)
 FS indicates a video frame which is delivered during the video frame one
 period.
 0 = Video frame 2 is delivered.
 1 = Video frame 1 is delivered.

 Table 17 – FF/FS for the 720-line system
 FF FS Output video frame
 1  1  Video frame 1 and video frame 2 are output in this order (1,2
 sequence).
 1  0  Video frame 2 and video frame 1 are output in this order (2,1
 sequence).
 0  1  Video frame 1 is output twice.
 0  0  Video frame 2 is output twice.
 }}}

 but this is for 720p (smpte 370m), not 720i.
