	Broadcast television system - Gurupedia
		An analogue television system includes several components: a set of technical parameters for the broadcast signal, a system for encoding color, and possibly a system for encoding multi-channel audio.
		Most video systems were defined to use negative modulation to reduce the appearance of noise, on the theory that dark spots in the image would be less noticeable than bright white spots in the image, given a particularly common sort of noise.
		The principal systems are NICAM, which uses a digital audio encoding; double-FM, in which case each audio channel is separately modulated in FM and added to the broadcast signal; and BTSC, which multiplexes additional audio channels on the existing FM audio carrier.

	Broadcast television system - Wikipedia, the free encyclopedia
		All current analogue television systems are interlaced; that is to say, alternate rows of the frame are transmitted in sequence, followed by the remaining rows in their sequence.
		All analogue television systems use vestigial sideband modulation, a form of amplitude modulation in which the lower sideband is incompletely suppressed.
		System A was tested with all three colour systems, and production equipment was designed and ready to be built; system A might have survived, as NTSC-A, had the British government not decided to harmonize with the rest of Europe on a 625-line video standard, implemented in Britain as PAL-I on UHF only.

	RCA COLOR TELEVISION SYSTEM
		Brightness is most clearly explained to television engineers by stating that it is the only characteristic of colors that is transmitted by an ordinary fl-and-white television system; brightness is that characteristic by means of which colors may be located in a scale ranging from fl (darkness) to maximum white.
		In analyzing and discussing television systems, it is customary to express signal voltages in relative or percentage units, such that 100% voltage in all three channels corresponds to the brightest white the system can reproduce.
		All systems of color television are based on the same calorimetric principles, regardless of the physical construction of the cameras and receivers or the methods used to combine the primary color images.

	Dane County Warning System Choices
		The Emergency Alert System is composed of AM, FM, and television broadcast stations as well as cable television, operating in cooperation with local authorities to provide uniform and consistent information in an emergency.
		Television, in particular, is an excellent source of emergency information since graphics such as radar displays and maps can be used to describe the event in detail.
		Broadcast television and radio, while being an excellent source of information, have one major disadvantage as a means of receiving warning.

	Encrypted broadcast television system - Patent 4736422
		A conditional access system for transmitting and receiving scrambled television signals over-air includes means for addressing each of the receiving apparatus with an over-air signal whereby to permit reception and descrambling of the signal.
		This is acceptable as long as the number of viewers is not considerable but where one is broadcasting to a considerable number of viewers, for example with satellite broadcasting, it can take a considerable time to access all the viewers with their own encrypted key signal to enable them to descramble the broadcast television signal.
		It is an object of the present invention to provide a system for sending encrypted programme entitlements together with a period key to one of a large number of viewers in such a way that he can relatively quickly access the encrypted entitlements and period key which enable him to decypher the scrambled teleivision signal.

	Television - Wikipedia, the free encyclopedia
		Television is a telecommunication system for broadcasting and receiving moving pictures and sound over a distance.
		While North American over-the-air broadcasting was originally free of direct marginal cost to the consumer (i.e., cost in excess of acquisition and upkeep of the hardware) and broadcasters were compensated primarily by receipt of advertising revenue, increasingly United States television consumers obtain their programming by subscription to cable television systems or direct-to-home satellite transmissions.
		Paralleling television's growing primacy in family life and society, an increasingly vocal chorus of legislators, scientists and parents are raising objections to the uncritical acceptance of the medium.

	Introduction to Television
		A television system uses one or more television cameras to convert the light energy of a natural moving visible scene, either in a television studio or outdoors, into an electronic signal.
		This signal is usually conveyed by line to a television transmitting station where it modulates a carrier source, and the resultant vision -modulated carrier wave is passed to the transmitting aerial to be radiated in all directions as a broadcast vision signal.
		The sound energy information associated with the visible scene is picked up by a microphone and converted into an electronic signal which is also passed by line to the transmitting station to modulate a separate carrier source.

		Television programs are clearly far more costly to produce and to transmit than radio programs, especially if they are broadcast over public networks and expected to meet production standards similar to those of news, documentary, and entertainment programs.
		Television comes into its own in a multiple-media distance education course—used to demonstrate scientific or laboratory experiments, to broadcast field trips, case studies, or performances, and to help visualize dynamic processes and sequences of events.
		And unless students have access to recording equipment, at home or at local study centers, the ephemeral nature of the broadcast must be taken into account in determining its educational objectives and its place in a distance course.

		Affirmed the 8-VSB modulation system of the DTV transmission standard, concluding that there is no reason to revisit its decision denying a request to allow use of an alternative DTV modulation standard.
		In raising this issue, the Commission recognized broadcasters’ concerns that DTV receivers are not yet available in sufficient volume to support a rapid transition to an all-digital broadcast television service.
		The Commission indicated that while it expects that consumers will continue to expect all digital television receivers to be able to receive over-the-air broadcast signals, it suggested that where receivers not able to receive such signals are marketed, consumers should be so notified prior to purchase.

		I also understand that if content transmitted over the air via broadcast television stations is not protected, content producers will be unwilling to supply broadcasters with their most valuable and highest quality programming.
		In short, broadcasters will become second-class citizens in the content chain and the American public, which now enjoys the finest free broadcast television system in the world, will suffer.
		The comments filed by Viacom in the FCC's broadcast flag proceeding (MB Docket No. 02-230) made that abundantly clear: Your company stated that if the FCC had not implemented a broadcast flag by this summer, it would not provide any programming in high definition for the 2003-2004 television season.
