Digital X Regular Television...

Analogic. i don't know what it was called befor turn out to digital.

Oh like the differance between digital and anaglog television? Whether or not you notice a difference will depend mostly on what kind of tv you have and what kind of digital signal you are getting. Most of the major networks broadcast in HD, so if you have the televesion and are getting the HD signal (via cable, soon it will be over the air in the U.S.) you can receive dolby digital 5.1 sound or better as well as a digital picture that is 720p-1080p depending on what service is available. An analog televesion does 480i, so yes there is a noticeable difference between the two.
