	North American broadcast television frequencies - Wikipedia, the free encyclopedia
		In North America, terrestrial television is broadcast on designated channels numbered 2 through 69.
		Traditionally, the frequencies are divided into two sections, the very high frequency (VHF) band and the ultra high frequency (UHF) band, but in reality, the VHF band is further subdivided into two more sections, VHF-Lo (band I) and VHF-Hi (band III).
		Channels 14 through 19 are used for two-way radio in major cities, intended for use on a non-interference basis, although the transition to digital television (DTV) has caused problems in certain instances when a previously unused channel has begun to be used for DTV broadcasts.

	North American cable television frequencies - Wikipedia, the free encyclopedia
		These channels are used for sending video back to the cable television headend, such as by public-access television stations on a cable tv system.
		Cable channels 2 through 13 operate on the same frequencies as broadcast television (the VHF band).
		Channels 100 to 125 can be used by analog cable systems, but frequency allocation is often inconsistent and not all televisions and VCRs can pick them up.

	The Ultimate Television - American History Information Guide and Reference
		Television in its original and still most popular form involves sending images and sound over radio waves in the VHF and UHF bands, which are received by a receiver (a television set).
		As a result, up until at least the mid-1970s, television stations would air announcements reminding viewers to unplug their sets before going to bed for the night, since the heat build-up in the back of the set was a not inconsiderable fire hazard.
		Paralleling television's growing primacy in family life and society, an increasingly vocal chorus of legislators, scientists and parents is raising objections to the uncritical acceptance of the medium.

	Satellite television
		The first North American satellite to carry television was Canada's Anik 1, which was launched in 1973.
		The television satellites are all in geosynchronous orbit, meaning that they stay in one place in the sky relative to the Earth.
		Television receive-only, or TVRO, refers to satellite television reception equipment that is based primarily on open standards equipment.

	Cable TV Channel Frequencies
		Cable channels operating on frequencies used in the aeronautical radiocommunications bands 118-137, 225-328.6 and 335.4-400 MHz are required to be offset by 12.5 kHz from 25 kHz-spaced channels [FCC Rules section 76.612 (a)].
		Cable channels operating on frequencies used in the aeronautical radiocommunications bands 108-118 and 328.6-335.4 MHz are required to be offset by 25 kHz from 50 kHz-spaced channels [FCC Rules section 76.612 (b)].
		The frequency of over-the-air broadcast channels 2 through 69 is specified in FCC Rule 73.603.

	High Definition Television (Site not responding. Last check: 2007-11-03)
		Also known as advanced television (ATV), extended-definition television (EDTV), and improved-definition television (IDTV), HDTV is an improved television system with at least double the horizontal and vertical resolution, wider aspect ratio, and superior audio when compared to the current television broadcast standards, e.g., NTSC and PAL.
		Broadcasters and cable operators are similarly concerned that the introduction of fiber optics by cable television and phone companies may allow the delivery of additional and competing services into the home.
		Broadcast and cable carriage of digital HDTV signals were tested under field conditions in Charlotte, North Carolina in the summer of 1995.

	Cable television headend - TheBestLinks.com - Head end, Frequency, Internet, Microwave, ... (Site not responding. Last check: 2007-11-03)
		Cable television headend is a master facility for receiving television signals for processing and distribution over a cable television system.
		The cable TV headend will normally have several large, television receive-only satellite television dishes for reception of cable/satellite TV networks such as ESPN, CNN, or HBO (examples); a dedicated, non-movable dish is required for each satellite that the cable TV utility wishes to receive cable channels off of for distribution over its system.
		Since each terrestrial channel represents a defined frequency, a dedicated commercial-grade receiving antenna is needed for each channel that the cable company wishes to receive and distribute.

	Annex V - The North American Free Trade Agreement (NAFTA)
		A cable television system is not allowed to carry any television broadcast signal if the cable system owns, operates, controls or has an interest in a television broadcast station whose Grade B contour overlaps the service area of such cable system (§ 76.501(a)).
		A cable television company may not lease excess transmission time or capacity from a licensee of an Instructional Television Fixed Service (ITFS) station (television services intended for use in educational institutions) if the ITFS station is located within 20 miles of that cable television company's franchise area (§ 74.931(e)(5)).
		In cable television franchise areas served by a single cable operator, that operator may not be authorized to use frequencies assigned to the Multichannel Multipoint Distribution Service (MMDS) (the 2150-2165 MHz and 2596-2644 MHz bands), if a portion of an MMDS station's protected service area lies within that cable television operator's franchise area (§ 21.912).

		The broadcasting of pictures by a few regular radio broadcasting stations, using frequencies in the broadcast band, has continued during the year 1928.
		At two demonstrations during 1928 the Bell Laboratories showed improvements in the television apparatus, the first consisting of the use of crystals for controlling the frequency of the transmitting and receiving apparatus, thus eliminating the necessity for the transmission of synchronizing current.
		On account of the great popular interest in television, it should be explained that the apparatus required is rather elaborate and that even under laboratory conditions the art has not yet come to near the stage of development required to reproduce scenes with the fineness of detail of the regular motion picture.

		From the start of commercial television in the 1940s until the emergence of color as the dominant programming medium in the mid-1960s, virtually all receivers were the direct-view monochrome type.
		Utilizing this phenomenon of physics, color television signals were first produced by optically combining the images from three color tubes, one for each of the red, green and blue primary transmitted colors.
		Television was formally launched in July 1941 when the FCC authorized the first two commercial TV stations to be constructed in the United States.

	North American MPEG-2 Information
		Broadcasters wanted the enconomy of digital transmission, but because MPEG-1 was not suitable for satellite and MPEG-2 was still being developed, a "bastardized" flavor of MPEG which I call MPEG-1.5 was created.
		The only service known in North America to be using statmux at this time is DISH Network, where it has made a huge difference to the quality of the video and at the same time allowed all the transponders FEC to be backed down to 3/4, therefore improving rain fade performance.
		Another North American use for ADXes is if you use a wide band LNB for Ku-Band that has a standard LO of 10.75GHz, but an output range of 950-2100 MHz.

		This frequency must be selected with great care, since it, including sidebands (also known as the "colour signal") resides wholly within the band of the luminance (also known as the "fl-and-white signal").
		This frequency is divided by 65536 in channel zero of the 8253/8254 to give the timer tick rate of 18.206507364909 Hz nominal, with a cycle period of 54.92541649846559 ms nominal.
		Because the NTSC colour subcarrier frequency, 3579545 Hz, divided by 372 becomes 9622.432..., which is close enough to 9600 to be used as a base for the common bit rate of 9600 bps.

	North American Transponder Market Could Top $2.5 Billion By 2010
		"The migration of broadcasting from analog to digital signals has reduced demand for new capacity because digital signals can be transmitted more efficiently, hence there is a reduction in the amount of satellite capacity required to transmit a given amount of content," says Frost & Sullivan Vice President Greg Caressi.
		Satellite operators have also become extremely cautious in adding further capacity to different frequencies that already have high fill rates while adopting a 'wait-and watch' approach in launching Ka-band enabled transponders.
		This research gauges both supply and demand for transponder capacity (C, Ku, and Ka frequency bands) that are leased by third parties for use in several applications such as video broadcast, telephony, Internet trunking, and networking.
