Since its inception, color TV has been broadcast in analog form and at a fixed resolution
Recently your local TV stations have started broadcasting their programming using
new TV Channels called Digital TV, or DTV. DTV allows TV stations to broadcast TV
programs at various levels of sharpness.
Sharpness that equals that of DVD’s is called Standard Definition TV, or SDTV. DTV
that is broadcast at the sharpest level is called High Definition TV, or HDTV. Programs
that are recorded and broadcast in HDTV are approximately four times as sharp as
SDTV, have better color, less noise, and a wider more movie screen like picture.
DTV replaced original analog TV in the US, for most channels, on February 17th, 2009.
Most UHF (14-69) and VHF (2-13) TV channels stopped broadcasting.
Local TV stations will only be broadcasting on their Digital TV channel frequencies.
Also, TV stations are taking advantage of DTV’s HDTV ability and are broadcasting
HDTV programs when available.
This has created confusion as consumers find they may need several pieces of new
equipment to watch HDTV, even if they continue to receive TV after February 17th
This guide serves as a means of understanding what’s involved in receiving HDTV,
explains your various options, lists what you need to own, and gives tips on how
