What does a HDTV means

[xanix]

I want to ask that what actually does HDTV means. I now the full form but what is actual difference between the old Television's and the New HDTV technology. Does it means a Digital Television. If I am spending a high amount in buying a HDTV does it is a proper deal. I had seen of HDTV's in a electronic mall which confuses a lot. I am not able to determine the difference. The only thing I can see that it is a flat television with a broader screen. Thanks in advance.

A HDTV is a new technology of Digital Television. It gives a aspect ratio of 16:9 which is similar to a resolution of movie theater. The HDTV gives you couple of more new advantages over the traditional TV. Like a wide screen and high resolution. The new rectangular wide screen gives a great look to eye as compare to the old TV. The main factor which increases the sale of HDTV is high resolution. They provide resolutions like 720p, 1080i and 1080p. The above numbers shows us number of lines to create and display image.
