23.976 =0.024 of the signal is used for A/V carrier offset due to the use of A/C oscillation as the basis for signal timing.

within monitor play back they are the same thing, no noticeable difference just a legacy of NTSC standard which is now used by the ATSC. they are the same thing, Seriously. 120hz/24fps = 5 fields per frame 120hz/23.976fps + .024fps delay for carrier offset = 5 fields per frame therefore 5=5.

This is the answer you were looking for!

EDIT: Fields should read static frames
