The goal of this study is to clarify the realistic viewing conditions and video signal characteristics surrounding flat panel display television (TV), as flat panel display television is becoming increasingly popular. We have conducted an investigation of TV viewing conditions in the home and the statistical characteristics of TV broadcast signals. Our study of viewing conditions indicates that the viewing environment at home is at minimum 3 times of the absolute display height with an average 2.5 m viewing distance, a less than $\pm 45$° TV viewing angle, and a 100–300 lx mean screen illuminance. Our analysis of the broadcast signal indicates that the velocity for the motion of a picture of a general TV program is distributed below 20°/s, visible camera blur is seen when the motion speed is higher than 10°/s, and average signal levels of TV broadcast in Japan are at 40 and 25% for ASL and ALL levels, respectively.
