The first step in knowing the essentials you need to consider before buying the HDTV is to become familiar with its basics. The following passages will let you understand what is HDTV, how does it work, and what is the future of HDTV.
What is HDTV?
HD stands for high definition, and it is the new standard of television viewing. HDTV is actually part of the Digital Television (DTV) specifications brought by the Advanced Television Systems Committee (ATSC). ATSC has defined eighteen different transmission formats, out of which six are considered ‘High Definition,’ because they constitute an incredible improvement over the resolution quality of a normal television.
HDTV has 1125 lines of resolution in comparison to 525 lines in the Regular NTSC analog signals. Thus, HDTV carries over five times the video information, as compared to your conventional NTSC analog TV set. In one way, it is the biggest advantage, and the other way it creates a hurdle because HDTV transmission requires an extraordinary bandwidth, five times the capacity of a conventional TV signal. True, they are five times better than your conventional TV, but then, they are 50% more expensive also.
