It is if interlace is not used, not if interlace is used.
For broadcast television, there is never enough bandwidth, so interlace
is used which halves the required bandwidth for very little visual
degradation. With a stationary picture such as a computer display,
interlace is not used, as it makes a stationary picture appear to
jitter vertically.
So interlaced 1080i at 50 or 60Hz has a frame rate of 25 or 30 FPS,
while progressive 1080p at 50 or 60Hz has a frame rate of 50 or 60 FPS.
