What is HDTV?
HDTV stands for High Definition Television. It is a digital format that provides an extremely high-resolution picture, accompanied by amazing digitally enhanced sound, all presented in glorious widescreen. What can be confusing is that HDTV is used to refer to several things: a type of TV, a digital broadcast method, and a special way to produce TV shows and movies. Viewing nirvana is achieved when all three parts of HDTV converge; a show or movie that is produced using High Definition technology, is transmitted via a HDTV television signal (from a HDTV channel), and enjoyed on a HDTV television (preferably a big widescreen set) with a surround sound home theatre audio set up. Still, even watching regular TV or a DVD on a HDTV is visually stunning. And that is why more and more people are getting on the HD bandwagon. 
 
Digital transmission uses less bandwidth to transmit more information than analogue transmission. Digital TV is totally free of interference such as snow and "ghosting". Standard Televisions have a resolution of 625i, HDTV has a higher resolution of either 720p, 1080i and in some cases 1080p, and 5.1-channel Surround Sound. And since it is digital, the signal doesn't lose strength and isn't susceptible to static and signal "noise".
