digital cable - Computer Definition
Cable television in digital form. Using MPEG encoding, digital cable is an enhanced service from the cable companies that provides an option to the regular analog TV. Advantages are on-screen program guides, a sharper picture and more channels of paid and on-demand programs. Unlike "digital satellite TV," which requires a dish on the roof, digital cable, also known as "digital terrestrial TV (DTTV)," is delivered over the same coaxial cable wired into the home or office. See DTV and plug-and-play TV.
