Answers: 1080i means 1080 lines of resolution displayed within an interlaced fashion. Which is to utter at 60 frames per second (or 59.94 frames per second in this case) 30 frames are the even scan lines and 30 are the unconventional scan lines and they alternate between them when displayed. Primarily you are talking in the region of sources and not display devices because LCD, Plasma and fixxed pixel projectors are all progressive scan and not interlaced. CRT and CRT projection TVs are interlaced but pretty infrequent now.
While these devices do a fine employment they are they are improved upon by 1080P TVs and source devices. These show adjectives 1080 lines every frame of the 60 displayed each second.
In both cases the TV or source device have to convert movies frame rate which is 24 frames per second (or in this baggage 23.98) to the 60 frames per second that the TV displays. Any conversion process introduces the possibility of errors so TVs that can display the 24 frames per second natively enjoy an plus. The best chance for this is a TV that have a 120Hz refresh rate because 120 is divisible by both 60 and 24 so these TVs do fine near both film and TV framerates.
Specifically some devices local framerates are slightly off the standard 60Hz or 24Hz and so High come to an end scalers like the IScan 50pro can shift the desired framerate to an exact framerate of the display device.
What you saw is probably that more exact home-grown framerate specification. Most manufacturers lately round it off at 24fps or 60fps.
