Technology has certainly changed the world. In our every day life we can see many changes in technology. Like say for live example yesterday I was searching for a digital camera. I found the latest one is 3MP (Mega pixel) and today I found that they came up with 4MP of digital camera in market. Unbelievable that fast is technology changing. Not only in digital camera, since last many years consumer electronic field have changed dramatically.

Something you may not have heard about yet, but will soon, is digital television, or DTV.

Later that year, the FCC established the Advisory Committee on Advanced Television Service (ACATS) to provide recommendations about ATV technical and economic issues. As discussion continued, all-digital ATV systems were developed, and ATV became DTV. In 1988, broadcasters and manufacturers funded the Advanced Television Test Center (ATTC) as a private, nonprofit organization to test new DTV technologies. Also that year, a group of cable television system operators established Cable Television Laboratories, Inc. (CableLabs) to work with the ATTC on the cable portions of DTV standards tests.
"In late 1996 the Federal Communications Commission (FCC) recommended a new digital television (DTV) system, proposed by the Advanced Television Systems Committee (ATSC), and Congress decided that by 2006,
