VGA - This acronym is short for the "Video Graphics Array" display mode. VGA resolution is 640 x 480 pixels.
Color temperature - This describes how white is displayed. Low temperature means slightly reddish, while high temperature means slightly bluish. Standard NTSC white corresponds to the color a glowing hot object would be at 6500ø K
Must-carry - This refers to the legal obligation of cable companies to carry analog or digital signals of over-the-air local broadcasters.
LCOS - (Liquid Crystal On Silicon) - This is another contender to replace CRTs in projection TVs.
Interlaced Scanning - This process divides and presents each video frame as two fields. Imagine a video frame being divided by the odd and even horizontal lines that make up the picture. The first field presents the odd lines; the second field represents the even lines. The fields are aligned and timed so that, with a still image, the human eye blends the two fields together and sees them as one. Motion in the image makes the fields noticeable. Interlace scanning allows only half the lines to be transmitted and presented at any given moment.
Bit Rate - The rate at which the data is transmitted, expressed as "bits per second" (bps). The higher the bit rate, the more data that is transmitted, generally resulting in better picture or sound quality. Video data rates are usually expressed as Megabits per second (Mbps, 106) and audio data rates in kilobits per second (kbps, 103).
Composite video. This 1-wire standard contains all video information: intensity, color, and sync. The encoding is the same as NTSC, and thus has the "overlapping sideband" problem which sometimes causes wrong colors to appear.
