HDTV
High Definition Television- An improved
television system which provides approximately twice the vertical and horizontal
resolution of existing television standards. It also provides audio quality
approaching that of compact discs.
HDTV is a new television standard that uses digital signals
rather than the current analog broadcast standard.
HDTV signals contain over 700 horizontal lines of
resolution, compared to the 525 lines of resolution that analog provides. HDTV
is also geared toward a rectangular wide screen format (16:9) for a true
theater-like experience.
HDTV images are digitized and compressed before signal
transmission to enable their tremendous quantity of information to pass through
easily. The signals are then decompressed when they reach the television. From
football to sitcoms, the result is a clear, crisp picture that brings every
broadcast to life with more detail and truer color than any other picture format
can offer.
