Nov, 5, 2005—More and more TV shows, movies and sporting events are being broadcast in High Definition (HD) —including “Good Morning America.” If you want to join the millions who are already experiencing a superior picture, you’ll need a High Definition TV (HDTV). But even if you’re ready to retire your old TV — or move it into the back bedroom where no one will ever see it —you’re bound to have lots of questions before you make an investment in a new drool-worthy HDTV.
You might be wondering about hardware, cost and how to actually receive High Definition programming on your set. “GMA” technology contributor Becky Worley offers this primer (入门书) to understanding the complicated world of HD.
What is HDTV ①?
High definition TV is a richer transmission of television signals that makes for a more vivid viewing experience. HDTV is to standard TV what FM radio is to AM radio. HDTV is crisp , clear and noise-free, with resolution that is at least twice that of analog (模拟信号)television and CD-quality sound .
How Do I Get HDTV ②?
HDTV signals are broadcast via antennas in urban areas, and via satellite TV or cable TV.
To receive an over-the air HDTV signal, you must live within a certain radius(半径)of an HDTV broadcast antenna and have the proper HDTV tuner (调谐器) / antenna (天线) installed in your home .
To receive a Cable or Satellite HDTV signal, you must have a proprietary HDTV set-top box supplied by your provider.
Not all programming is available in HDTV yet, but many network shows and sporting events are currently in HD and many more are converting over.
When you watch a DVD on your HDTV, it is not technically HDTV quality, but it will look crisper on your HDTV than on a regular TV.
HDTV, HD-Ready TV, and EDTV
There are three major terms that will describe the high-end TV sets that are on sale today :HDTV ③ are TV sets that can receive and process over-the-air HD signals. You may need an antenna to receive the HD signal, but an HD tuner is built into the set and can process the signal without any other equipment. If you want to receive an HD signal from your cable or satellite provider, you will need one of the provider’s proprietary set-top boxes.
HD-Ready TV are TV sets that need an additional piece of hardware to actually receive the HD signal, such as a stand-alone HD tuner (from $250 and up) or the set-top HDTV box provided by your cable or satellite TV company.
EDTV stands for Enhanced Digital Television. The visual quality of an EDTV is better than a standard analog TV, but is not as crisp or bright as a true HDTV.
