Digital Television
A digital television is defined as any TV set that can accept and
display a decoded digital signal (or a stream of ones and zeros).
HDTV is one of many digital formats, which adds to the confusion.
Digital televisions can typically display more lines of resolution
than today's decades-old 480-line broadcasts.
Digital televisions can also
display images in progressive-scan mode, which draws the screen in
one pass (like a computer monitor) rather than two passes of odd and
even interlaced horizontal lines. Most digital TVs are capable of
supporting anywhere from 480 lines to 1,080 lines of horizontal
resolution in progressive or interlaced modes at either 4:3 or 16:9
aspect ratios.
Since current DVDs are formatted to display digital
progressive 720x480 resolution, digital televisions make sense for
consumers who are committed to DVD quality and detail but don't care
to invest in higher-resolution televisions that support 16:9 1080i/p
HDTV signals.
Digital TV is available on certain channels over the
air depending on where you live, through digital broadcasts from
digital satellite services (DSS), or from digital cable.
Digital televisions can display a picture that shows truly outstanding detail,
depth of focus, and a much more realistic sense of space,
particularly under higher HDTV resolutions at native 16:9 aspect
ratios. Higher resolutions and progressive scanning add to colour
depth and saturation, help reduce interlace glimmer effects, and
generally come closer to what was shot in the first place by the
camera crew.
