I made that suggestion about six years ago in this discussion group for
60Hz NTSC for the transition, but was shot down. I later found Charlie
Rhodes proposed the same thing some years earlier.
No, I think anyone should impose the offset NTSC frame rates. But I think
the 1080i and 720p equipment which can handle 60.00Hz, should be considered.
It is a shame that 50 Hertz may be later thrown into the mix.
