Some Knowledge

Ultra HD is Ultra High Definition television.  Common HDTV uses 1920 x 1080 pixels.  Ultra, developed by NHK of Japan, has 16 times as many pixels.  It is broadcast in 7680 x 4320 pixels.  The bandwidth consumed by an Ultra HD signal requires fiber optic cabling.  It is proposed to come to market in 2025.

Ultra HD is broadcast with 24 channels of sound.  It uses MPEG-4 compression on each of the 16 HD segments that make up the image to reduce bandwidth requirements.  First demonstrated in 2003, Ultra HD has been exhibited at various expos and conferences around the world.  The experience is said to be much like viewing a scene in person, with some people aquiring vertigo from viewing this broadcast.

It is proposed that Ultra HD will eventually replace the HDTV that is becoming standard today.  The proposed high bandwidth of the signal will require dedicated gigabit fiber optic connections to any house served by this technology.  For the present, Ultra HD is much like IMAX movies, in that it is only available at specific demonstrations meant to showcase new technology.
