Probably just a byte with a number in it. It wouldn't
even need to know anything about the aspect ratio,
just how much unsqueeze to perform.

Well, my 4:3 composite monitors have no problem
displaying anamorphic 16:9 content as a letterboxed
16:9 image, so I'm sure that a 16:9 screen could be
given data to output a letterboxed 2.25:1 image.

I don't see why it shouldn't be for all aspect ratios
(within a certain range). It seems to me it would
actually be harder to implement for specific aspect
ratios than to just make it generic.

It sounds like these formats will handle less aspect
ratios than DVD. So we will have to wait for yet
another format in the future. :(
