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.
