    "abstract": "An ultrahigh-definition video system is considered to be a prospective candidate for future broadcasting services providing a high sensation of reality. This paper will discuss the design considerations in the construction of an experimental ultrahigh-definition video system with 4000 scanning lines. The scanning parameters were determined based on the relationship between the sensation of reality and the viewing angle. The camera system was developed based on the four-CCD (charge-coupled device) image-acquisition technology: two 2.5-in. 8M-pixel CCDs are used for green, and one each for red and blue. The four-CCD beam-splitting system incorporates two-dimensional pixel offset to form a Bayer color-sampling pattern with the CCDs. A 4000-scanning-line display system was also developed. It is similar to the imaging system, which uses four 8M-pixel LCDs to realize a 4000-scanning-line system, one each for red and blue, and two for green with diagonal pixel offset. The viewing angle is more than 100° horizontally, at a standard viewing position of 3 m from a 320-in. (7 × 4 m) screen.",
