What is High Definition Television?
Although High Definition Television has a very short history, it has continuously playe a major role in the transformation of digital home entertainment space. The credit goes to the satellite TV service providers, who have made it such a hot cake item today.
It all started almost 15 years ago in 1987, when FCC (The Federal Communications Commission) issued a rule stating that that high definition television standards must be compatible with existing NTSC service. However, later in 1990, General Instrument Corporation proposed for an all-digital High Definition Television system. By the end of 1990, four serious contenders in the United States, ATRC, Zenith HDTV, AT&T, and MIT, announced their digital entry in HDTV system. Then 1993 was a remarkable year in the history of HDTV in the US, when a grand Alliance was formed. The alliance included major players such as, AT&T, GI, MIT, Phillips, Sarnoff, Thomson, and Zenith. Their task was to take the best features from the four HDTV systems and develop a standard HDTV system. They successfully tested it in 1995 and the FCC set it as the HDTV standard.
"HD" stands for high definition, and 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 defined 18 different transmission formats, out of which 6 are considered ‘High Definition,’ because they constitute an incredible improvement over the resolution quality of a normal television.
High Definition Television has 1125 lines of resolution in comparison to 525 lines in the Regular NTSC analog signals. In other words, High Definition Television carries over five times the video information, as compared to your conventional analog TV set. It's two-fold. In one sense, it's a huge advantage and in another, it creates a hurdle because in transmission because of the additional, extraordinary bandwith (as stated over times the capacity of a conventional TV signal). So, they're more of an investment than an expense. You get 5 times more quality of a conventional tv in the long run with a High Definition Television. more...
