What HDTV Is

Digital describes electronic technology that generates, stores, and processes data in terms of two states: positive and non-positive. Positive is expressed or represented by the number 1 and non-positive by the number 0 (Lasica). Data that is transmitted or stored with digital technology is expressed as a string of 0's and 1's. Each of these digits is referred too as a bit (and a string of bits that a computer can address individually as a group is a byte).
Prior to digital technology, electronic transmission was limited to analog technology, which conveys data as electronic signals of varying frequency or amplitude that are added to carrier waves of a given frequency (Lasica). Broadcast and phone transmission has conventionally used analog technology. Digital technology is primarily used with new physical communications media, such as satellite and fiber optic transmission. The first digital transmission was Morse code. A modem is used to convert the digital information in your computer to analog signals for your phone line and to convert analog phone signals to digital information for your computer. Newer distribution technologies-such as direct broadcast satellites (DBS), videocassette recorders (VCRs) and cable-are in heavy competition with over-the-air broadcasting for audiences of over 600 million television viewers worldwide (Lasica).
In the United States, the political and economic stakes have changed since the beginning of the development of television. The standardization and commercialization of new television technologies affect culture through social, political, economic, institutional, industrial, and aesthetic factors that influence the strategies and policies of both industry and government. Technological developments in television have brought new products and processes for manufacturers, broadcasters, and regulatory agencies (Television Standard).
For example, looking specifically at economics, new technological developments in reception will change the stakes of that market. Advanced forms of television receivers capable of displaying higher definition pictures will probably be available as early as.
HDTV is defined as a television system that differs from current television systems-such as the North American and Japanese NTSC System-in the following ways: five times the increase in visual information detail, 10 times the color information, more than double the horizontal and vertical resolution, substantial improvement in picture brightness, over a one-third increase in aspect ratio (from 4:3 to 5.33:3), and sound quality equivalent to digital compact disc audio (Television Standard). Although the term HDTV is now used to refer to a new development in television technology, the term "high definition" has historically been used to define a number of advances in television picture quality. RCA first used the term "high definition television" in its 1934 Annual Report, identifying the role HDTV would play in the commercialization of television. Also in 1934, Vladimir Zworykin-a leading pioneer in the development of electronic television-defined the parameters for HDTV "regarding 240 scanning lines as a minimum." Overseas, a British engineering report from the Royal Television Committee in London offered a similar technical definition for HDTV. In this article, Zworykin's HDTV definition of 240 lines or greater will be used (Kuhn).
There are many different formats associated with High Definition TV. The ATSC recommendations have been characterized by the computer industry as "a confusing collection of 18 different standards that will be unnecessarily difficult and expensive to implement by set manufacturers"(Television Standard). However, the computer industry does not build or market television sets like other set manufacturers do. These manufacturers believe that sets can be made and sold to consumers that will accommodate all of these standards, similar to the way that multi-sync monitors accommodate the many incompatible computer display formats in use today (Kuhn). The forma...
