The color difference channels (B-Y and R-Y) are algebraically recombined with the
luminance channel to produce a full color picture, recreating the green information
through this mathematical process. The original green data can consume more than
half the bandwidth of a video signal.
NOTE: Color space is a method used to specify, create and visualize color. Color is
defined by three attributes: brightness, hue and intensity. These three dimensions of
color exist in a mathematical three-dimensional space, making it possible to specify
precise colors.

Video Standards

HDTV (High Definition Television)

High-definition television is a high-resolution digital television broadcast and
playback system composed of roughly a million or more pixels (picture elements),
16:9 aspect-ratio screens, and AC3 (Dolby Digital six-channel digital audio
standard). A subset of digital television, HDTV formats include 1080i and 720p
resolution.
1080i
A designated format of high-definition television in the Advanced Television
Systems Committee Digital TV standard, with 1,080 vertical pixels by 1,920
horizontal pixels. The i stands for interlaced, painting odd-numbered scan lines in
succession, then going back and filling in the remaining even-numbered lines. A
complete picture is created 30 times per second. 1080i is a high-resolution digital
television broadcast and playback system composed of roughly a million or more
pixels (picture elements), 16:9 aspect-ratio screens, and AC3 (the Dolby Digital six-
channel digital audio standard). The signal is supplied in Component format; Y

Society of Motion Picture and Television Engineers (SMPTE) as 274m, 59.94 Hz
(60 Hz) vertical and 33.716 kHz horizontal (33.75 kHz), 0.600 volts peak-to-peak.
720p
A format designated as high-definition television in the Advanced Television
Systems Committee Digital TV standard. This technology comprises 720 vertical
pixels and 1,280 horizontal pixels. The p stands for progressive, also called
sequential scanning, by which all odd and even scanning lines are "painted" by an
electron beam every 1/60 of a second. ). To use a 720p resolution with the UPX-2 it
must be first converted to RGB. Crestron recommends a converter made by Key
Digital Systems, model number KD-CTCAL (www.keydigital.com) for this
application.
720p is designated by the Society of Motion Picture and Television Engineers
(SMPTE) as 296m, 59.94 Hz (60 Hz) vertical and 33.716 kHz horizontal (33.75
kHz), 0.600 volts peak-to-peak.

SDTV (Standard Definition Television)

Digital television format that includes 480-line resolution in both interlaced (480i)
and progressively scanned (480p) formats, and offers discernible improvement over
