16 - 9 - Aspect ratio of widescreen DTV formats for all HDTV and some SDTV (Standard Definition) content, 16 unit width by to 9 unit height.
PCM - (Pulse Code Modulation) - This 2-channel digital audio standard is simpler than Dolby Digital.
Pixels Per Inch - Pixels per inch (PPI) is a measure of the sharpness (that is, the density of illuminated points) on a television display screen.
HDTV - "High-definition Television." This is the most superior video picture available in Digital TV. In the U.S., the 1080i and 720p formats in a 16:9 aspect ratio are the two acceptable HDTV formats. HDTV is a component of DTV.
Analog Video - The conventional NTSC television system in use today uses analog technology, in which the image sound and the picture brightness and color are represented by signals proportional to these values. The values of these signals are vulnerable to interference and noise. Digital television overcomes this vulnerability and delivers signals that are totally clean.
Wide screen - A term given to picture displays with a wider aspect ratio than NTSC 4:3. Digital HDTV or SDTV is referred to as "16:9 wide screen." Most motion pictures also have a 16:9 wide screen aspect ratio. Most Digital TVs have a screen that is wider than it is tall (if a Digital TV screen is nine inches high, it's 16 inches wide.) When watching a show recorded in the wide screen format on a Digital TV, viewers see more of the movie, while when viewing wide screen format on an analog TV, cropped edges are evident.
Enhanced TV - Also known as "datacasting." This term is used for certain digital on-air programming that includes additional resources downloaded to viewers. Some forms of enhanced TV allow live interaction; other forms are not visible on-screen until later recalled by viewers. Producers add these options to some digital programming to enhance program material -- allowing viewers the ability to download related program resources to specially equipped computers, cache boxes, set-top boxes, or DTV receivers.
