Is there such thing as 1080i 59.94 fps or 59.94 fields to be correct?
I’m confused on the network delivery for 1080i at 59.94 fps. Is this supposed to be read as 59.94 fields instead?
The specs: 1920×1080 interlaced, upper field first, dropped frame tc, 59.94 fps.
But for SD, 720×480 interlaced, upper field first, dropped frame tc, 29.97 fps.
I have never heard of 59.94 fps to be in 1080i. I only see that in 1080p. And 1080p is not really a broadcasting standards if I’m not mistaken. More of a camera acquisition and local playback format.

Delivery spec terminology is often confusing. This is a standard broadcast delivery spec. 1080i/59.94 means fields. So 1080i/59.94 is the same as 1080i/29.97, just that in the first it means fields and in the second it means interlaced frames (2 fields per frame).
