The tolerances on analog TVs are loose enough that they won't even notice a slight increase in frame rate.

Although these days, that is all mostly irrelevant. Many countries, including Australia did away with analog TV transmissions years ago. Now all we have to do is get rid of interlacing and everything will be peachy.

Hear, hear!!!

I am actually irrationally angry that digital video standards (other than than 480i, which matched the analog SD signal, and which predates the HD standards) even include interlaced modes. It never made sense for 1080i to even exist, given that practically no TVs exist that can display it truly natively! (How many CRT HDTVs are there out there, really??)

Bud:
With interlaced method of transmission you send half of the picture 50 or 60 times per second. With progressive method you send full picture at full resolution each time, therefore doubling the bandwidth. I can speculate that 1080i may have to do with lower bandwidth media including perhaps interconnecting cables. It would be less demanding to the system throughput than 1080p.

It looks shit, mainly on LCDs.

Tooki, don't tell me that you can see the difference between 50Hz and 60Hz flicker with a naked eye and in the absence of flickering ambient lighting (i.e. no fluorescents or flickering LEDs around).

With regards to CRT TVs? Absolutely. It’s clearly visible, especially in peripheral vision. 60Hz really is the lower bound for being flicker free, 50Hz is just below it. There’s a reason 100Hz (50Hz x2) TVs were developed, but nobody ever had to make 120Hz (60Hz x2) TVs. It’s why cinemas used, at rock bottom minimum, frame rate doubling projectors (48fps) but preferred frame-tripling (72fps) to ensure no flicker.
