VGA - This acronym is short for the "Video Graphics Array" display mode. VGA resolution is 640 x 480 pixels.
Upconverting - Process by which a standard definition picture is changed to a simulated high-definition picture.
HDTV - (High Definition TV) - A TV that displays 1280x720 pixels or better.
Resolution - The level of resolution directly affects picture quality. The higher the resolution, the more picture detail there is. Many things affect picture quality, including number of bits, pixel count, format, receiver quality, cameras, lenses and lighting used for live or taped programming. Resolution is measured by the number of pixels displayed. One of the high-definition picture formats is composed of 1080 active lines, and each line is composed of 1920 active pixels. Therefore, each frame has over 2 million (1080x1920=2,073,600) color pixels creating the image. By way of contrast, today's typical analog television is roughly equivalent to 480 active lines, with each line holding about 440 pixels. So, each frame has a little over 200,000 color pixels in use creating the image.
Aspect ratio - The ratio of screen width to screen height. For TVs it is either 4:3 (1.33:1) or 16:9 (1.78:1). Theater film uses many different aspect ratios, some as high as 2.5:1.
THX - 1. a standard that theaters try to meet. 2. equipment to help theaters meet that standard.
AC-3 - The 5.1-channel compressed digital sound system specified for DTV broadcasting in Canada. AC-3 delivers CD-quality digital audio and provides five full-bandwidth channels for front left, front right, center, surround left and surround right speakers, plus an LFE (low frequency effect) subwoofer, for a total of 5.1 channels. AC-3 is one member of a family of sound systems developed by Dolby Labs.
