	Digital television - Wikipedia, the free encyclopedia
		Digital television (DTV) is a telecommunication system for broadcasting and receiving moving pictures and sound by means of digital signals, in contrast to analog signals in analog (traditional) TV.
		It uses digital modulation data, which is digitally compressed and requires decoding by a specially designed television set or a standard receiver with a set-top box.
		All early SDTV television standards were analog in nature, and SDTV digital television systems derive much of their structure from the need to be compatible with analog television.

		Digital terrestrial television (DTT) is in the process of deployment in a number of countries.
		Today most viewers receive digital television via a set-top box, which decodes the digital signals into signals that analog televisions can understand, but a slowly growing number of TV sets with integrated receivers are already available.
		Digital teletext is supposed to provide interactive services, but for this a separate "return path", such as a telephone line or Internet connection, is required.

	Digital terrestrial television - Wikipedia, the free encyclopedia
		Digital Terrestrial Television (DTTV or DTT) is an implementation of digital technology to provide a greater number of channels (SDTV) and/or better quality of picture (EDTV, HDTV) and sound (AC3, Dolby Digital) through a conventional antenna (or aerial) instead of a satellite dish or cable connection.
		DTTV is transmitted on radio frequencies that are similar to standard analog television, with the primary difference being the use of multiplex transmitters to allow reception of multiple channels on a single frequency range (such as a UHF or VHF channel).
		The UK DTT was relaunched as a free-to-air platform ("Freeview") in 2002 and the UK DTT currently leads the world in terms digital television penetration (along with Finland).

	Digital Television
		Digital television is the application of digital technology to television to the process of producing and transmitting television programming.
		Television was developed as an "analog" medium, but the replacement of analog technology with digital technology throughout the television production and transmission process promises to increase the capabilities of the medium.
		The term "digital" refers to a type of electronic signal in which the information is stored in a sequence of binary numbers ("on" or "off", representing one and zero) rather than in a continuously varying signal (known as an analog signal).

		The FCC Order called digital television "a technological breakthrough" and reaffirmed the national policy to "...preserve and promote universal, free, over-the-air television." The FCC considered a schedule of 15 years for adoption of a digital TV system, but decided on a more ambitious target date of 2006 for ceasing the broadcasting of analog television.
		Digital is a form of encoding in which the waveform of a signal is represented as a series of digits, which are then encoded as binary "0s" and "1s," or as "ONs" and OFFs." Since digits rather than an analog of the waveform are encoded, the digital representation allows near perfect storage and transmission.
		Digital TV can also mean multicasting in which a number of conventional (but digitized) TV signals are sent in the space of a single channel.

	Reason: Prisoners of Digital Television: A misadventure in high-tech regulatory policy -- and a Harry Potter Fix
		Tuner mandates, such as the FCC’s recent requirement that all high-definition televisions (HDTVs) carry both analog and digital TV-signal receivers, mean an added expense per unit at a time when the industry is hoping economies of scale will reduce their costs and get more buyers into stores for crisper, even "cinema-quality," TV displays.
		Meanwhile, one looming problem has not even begun to be addressed: In-the-field tests of television sets equipped with digital tuners suggest that DTV reception -- at least under the technical standard digital broadcasters are currently required to use, dubbed 8VSB -- is not as reliable as analog broadcast reception.
		Those that wanted to continue analog broadcasting but continue to build out to, or experiment with, digital broadcasting could choose to buy or license additional spectrum, more of which should be available once the "loaned" spectrum has been reclaimed by the Commission, acting as a proxy for the general public.
