Invited paper:: Super Hi-vision projection display for next-generation TV

For future broadcasting, NHK is studying new video services offering very-high-picture quality achieved through Super Hi-Vision. Toward that aim, a projection display that has a resolution equivalent to 7680 x 4320 pixels by using four 4096 x 2160 D-ILA (TM) panels has been developed. The display requires precise convergence adjustment because it consists of two projection units, so an automatic adjustment system was developed. Although the pixel number of the digital camera used is less than that of the display, a 0.2-pixel accuracy was obtained. This report introduces theaters that use this display as an example of applying the Super Hi-Vision video system.
