This is designed for 21:9 displays and those of us that use an A-Lens with our projectors.
If you don't have an A-Lens or a 21:9 TV and want to view this type of program, you would need a VP to vertically compress the image and generate black bars top and bottom.
If the format gets approved by the BDA and is encoded correctly, the letterboxed version will be what provides backwards compatibility with all existing systems.
I love my Constant Image Height system!
