The hot trend in DVD players today is an upconverting DVD player that comes close to real high definition DVD players

The hot trend in DVD players today is an upconverting DVD player that sends an HDTV a high definition image matched to the native resolution of the particular display device (normally 720p or 1080i).

Because the upconversion is processed by the player in direct sequence with the MPEG decoding then passed digitally to the display device, the results can be astonishing and far better than can be achieved by using the onboard scalers used by today's HDTVs.

HDTVs can either accept HD images via component, DVI, or HDMI and llder sets use component, which is analogue, and may not support the new digital input technologies (DVI and HDMI).

Most new HDTVs purchased in or after the second half of 2004 have an HDMI input. HDMI is basically similar to DVI in that both pass digital video signals, except that it includes additional support for sound and also a separate "info" channel which will allow for a number of uses including auto calibration between display devices and A/V sources.
