High-Definition Television
High-Definition Television or HDTV is a digital television format
delivering theater-quality pictures and CD-quality sound. HDTV offers
an increase in picture quality by providing up to 1,920 active
horizontal pixels by 1,080 active scanning lines, representing an image
resolution of more than two million pixels. In addition to providing
improved picture quality with more visible detail, hi-def offers a
widescreen format and Dolby® Digital 5.1 surround sound. Cable program
networks have been at the forefront of providing HD programming, and
cable operators began delivering HD service in earnest to customers in
2002. Deployment has been on an upward arc ever since. The cable
industry is also working closely with television set manufacturers to
ensure that consumers receive HD in the most convenient and
user-friendly ways possible.
