Hdtv antenna, or converter box...you'll have to decide!
The High Definition Television (HDTV) is a digital format for transmitting and viewing TV programming. Sharper images are received in various ways to an HDTV.
First you have the hdtv antenna which looks just like the old relics back in the '60's and '70's. Second, you can acquire them via your Cable/Dish provider's receiver box or acquire an analog device box. There are a wide variety of reasons for purchasing a HDTV.
Many of the reasons to debate making the transfer to an HDTV are: Higher caliber audio you will instantly notice, wider viewing area and surprising detail. HDTV's can accomplish up to 1920 (horizontal) pixels x 1080 (vertical) pixels, with an dazzling total of 2,073,600 pixels per image.
One situation you will not miss with HDTV signals via a hdtv antenna or the other methods mentioned earlier is no more shadow images! As you know signal quality was not something that was always perfect when viewing a standard television. The results are simply awesome!.
The reason is that signals of an NTSC HDTV television are shown as interlaced signals, which means that every other horizontal line on the hdtv monitor is shown in one frame, and the other half are drawn in the next frame of the image.
This tricks the eye into believing that only one picture is being shown. HDTV progressive scanning, nevertheless, shows the full picture in one frame. This gives it a slightly sharper image, which is better than that of an interlaced image with the same resolution.
There are two progressive HDTV formats accessible for broadcasters, the 480p and 720p. The 480p provides a much sharper appearance than a standard NTSC broadcast. However, it is only a DTV communication and not a accurate High Definition signal.
The 720p HDTV signal is made up of 720 horizontal scan lines, and is considered to be actual HDTV High Definition. As Feb 17, 2009 (when all stations must transfer to digital broadcasting) approaches it seems that more and more consumers crosswise the country will be getting there HDTV signal via an hdtv antenna.
Nearly 20-30 million Americans now get there analog signals via a standard antenna. These people will have to select after this date to either purchase an analog converter box , get their hdtv signal via a Cable/Dish provider or swap out their old uneffective analog antenna with a hdtv antenna to maintain watching TV.
