Okay if I'm interpreting your enquiry correctly...
Kine recording is done [in North America in your case] at either 24 or 30 frames per second. Your TV system is 30 frames per second, but when we take the anti-flicker interlace process into consideration, its really 60 half-resolution frames per second. [Otherwise known as fields.]
So to preserve the "anti flicker effect of interlace" the kine camera would need to run at 60fps, recording each field. [And the subsequent telecine of the kine also at 60fps.]
Hope I've answered your question - clearly
On a related matter - conventional 24fps cinema projection also uses an anti-flicker process: two-bladed shutters. So each frame is flashed on the screen twice - 48 flashes per second.
