Basics Of HDTV
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.
A Brief History of HDTV
Although HDTV has a very short history, in it has been playing a major role in the transformation of digital home entertainment space. The credit goes to the satellite TV service providers, who have made HDTV such a hot cake today.
It all started almost 15 years ago in 1987, when FCC (The Federal Communications Commission) issued a rule stating that that HDTV standard must be compatible with existing NTSC service. However, later in 1990, General Instrument Corporation proposed for an all-digital HDTV 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.
