high-definition television

Type of digital television system offering a significantly greater number of scanning lines, and therefore a clearer picture, than that provided by conventional systems. Typically, HDTV has about twice the horizontal and vertical resolution of current 525-line (such as the American standard, NTSC) or 625-line standards (such as the British standard, PAL); a frame rate of at least 24 Hz; and a picture aspect ratio of 9:16 instead of the current 3:4. HDTV systems are rapidly being introduced in many countries.

In May 2003 the US Federal Communications Commission (FCC) regulated that all commercial and non-commercial TV stations in the USA must begin digital broadcasts for at least part of their operational schedule. The FCC set a target that all TV stations must simulcast all of their NTSC programming on a digital channel by April 2005. Federal law now requires that all analog TV broadcasts in the USA should end by February 2009.

There's the plug 'n play ATI TV Wonder 600 USB, which should have no problem tuning OTA HD on any machine equipped with USB, and also comes bundled with an IR remote, AV input, and Catalyst Media Center software.
