Prothero and H.G. Hoffman then come back here and argue some more. -----Original Message----- From: opendtv-bounce@xxxxxxxxxxxxx [mailto:opendtv-bounce@xxxxxxxxxxxxx]On Behalf Of Manfredi, Albert E Sent: Tuesday, November 02, 2004 4:08 PM To: OpenDTV (E-mail) Subject: [opendtv] Re: (No Date: Tue, 28 Sep 2004 10:30:37 -0400 Craig Birkmaier wrote: > I went back through the list archived to try to > find other references, since we have been down > this path before.

Vertical field of view is not just less than horizontal field of view, in terms of peripheral vision, as the "standard eye" figures showed, but it is also less than horizontal field of view when you add in the effect of eye and head movements. That same "standard eye" tells the story about eye movement speed. Although you made a mention of that once, you then conveniently forgot to take it under consideration this time. Hence, your claim that human field of view is more like 1:1 was way off base. > So why are you so adamant about a particular > aspect ratio, when you are not even motivated > to go buy a set with a big wide screen? I am adamant about seeing a sensible standard for next generation TVs get implemented, rather than creating a standard based on dogmatic political positions, on misunderstood technical facts, or on misapplication of solutions which might or might not make sense for personal computers. Luckily for me, it looks like common sense is prevailing in the real world.
