	Television (Site not responding. Last check: 2007-11-02)
		A semi-mechanical analogue television system was first demonstrated in London in February 1924 by John Logie Baird and a moving picture by Baird on October 30 1925.
		The earliest television sets were radios with the addition of a television device consisting of a neon tube with a mechanically spinning disk (the Nipkow disk, invented by Paul Gottlieb Nipkow) that produced a red postage-stamp size image.
		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).

		Independent Television (ITV) is the name given to the original commercial British television broadcasters, set up in 1955 to provide competition to the BBC.
		No further analogue broadcasters are expected to be launched, and efforts are being made to move analogue channels to digital television so that the bandwidth allocated to analogue television can be reused.
		Digital terrestrial television was originally launched as a subscription-based service by a company called ONdigital, later ITV Digital, which failed commercially.

	Shutdown \| Bitstream
		Analogue terrestrial broadcasts occupy what are known as channel numbers, with each number representing a particular frequency (like those shown on the dial of a radio except they are different values) and put simply, an individual channel number is used to broadcast a single television channel.
		With analogue transmissions you cannot have two transmitters using the same channel number if there is any chance of both transmissions being receivable from one location otherwise there would be interference between the two signals, so adjacent transmitters have to use different channel numbers for the same transmissions to avoid interference.
		Certain unusual weather conditions can make television transmissions travel unusually long distances, which is the reason why there are occasional warnings that television pictures can suffer what is known as “co-channel interference”, so to minimise the risk of this happening the channel numbers have to be as different as possible within a very wide region.

	Broadcast television system - Gurupedia
		A monochrome image is theoretically continuous, and thus unlimited in horizontal resolution, but to make television practical a limit had to be placed on the bandwidth of the television signal, which puts an ultimate limit on the horizontal resolution possible.
		Usually it is closely related to the frequency at which the electric power grid operates, to avoid the appearance of a flicker resulting from the beat between the television screen and nearby electric lights.
		Since television was originally implemented using cathode-ray tubes, the physics of these devices necessarily intrudes on the format of the video they can be used to display.

		Analogue cable television is distributed from a relay station to our homes along optical cables and are less subject to interference.

		The analogue signals are converted to light pulses, and the cable can only carry a certain number of these pulses.

	Digital Television Explained.
		Today's television is called analogue PAL because continuously variable images (the analogue picture) are modulated onto (added to) the analogue radio carrier wave (the channel's tuneable radio frequency).
		When I built a small television studio at the Australian Film, Radio and Television School in 1977 we spent about a quarter of the budget on a digital time-base corrector (TBC) to stop the side-ways shake of lines generated by the early videotape recorders.
		In all case, we are just converting digital video into digital television by modulating it in a digital way, instead of the old analogue way, for the distance of the aerial hop.

	Digital Broadcasting Australia
		Outside of the major metropolitan areas, digital television transmissions have begun in many of the major regional centres and are continuing to be implemented at a rate of approximately two transmitters a week.
		Free to view broadcasters will simulcast (broadcast both analogue and digital signals) for at least eight years in an area, so metropolitan viewers will continue to be able to use current analogue television sets to receive broadcasts without the need for a set top box until at least the end of 2008.
		Analogue television sets currently in use in Australia cannot display digital transmissions on their screens without being connected to such a digital television set top box receiver.

		It's hoped that existing analogue television will be switched off throughout the country by 2012 to be replaced with a new digital technology offering more channels, greater interactivity and cost savings for broadcasters which can be put back into programmes.
		When television became a household item over 75 years ago, the broadcasts were made in fl and white and using analogue signals only.
		Digital television platforms have differing levels of interactivity for the viewer, mainly dependant on the 'return path', which means that the user’s equipment can communicate with the broadcaster.

		Each and every piece of audio/video equipment you own that receives analogue television signals will be affected by switchover.
		If your television only has an analogue tuner (the component which turns the signals from your aerial into pictures for your screen), then it will no longer be able to display analogue television pictures after analogue switch-off.

	World Analogue Television Standards and Waveforms - Line Standards
		In the UK the 405-line system was brought out of mothballs (television transmissions had ceased two days before the start of the war), despite EMI's recommendation for a 605-line standard (there was also a proposal for a 1 000-line standard for use in cinemas).
		Russia was also a pioneer in television services, starting with 30-line tests in the mid-thirties, changing to higher definition standards in 1937, and the situation there too seems to have become rather chaotic.
		The preferred shape of all pulses is Raised Cosine (that is the portion of a sine wave between -90° and +90° for positive slopes and between +90° and +270° for negative slopes).

	World Analogue Television Standards and Waveforms
		John Logie Baird (of course) was the first to demonstrate colour television using a field-sequential version of his 30-line standard, but during the war he also had a hand in developing high-quality electronic systems and came up with his 'Telechrome' two-and three-gun display tubes.
		NTSC is named after the National Television Systems Committee which had been set up in 1940 by the RMA (Radio Manufactureres Association) and was asked in 1949 to find a compatible colour television standard for the USA to replace the incompatible field-sequential colour system that had been used since 1948.
		MAC, Multiplexed Analogue Component was a system devised in the UK by the Independent Broadcating Authority (IBA) for delivering high quality colour pictures via direct broadcast satellites that would be independent of European countries' individual choice of (terrestrial) colour coding standard.

		"It is proposed that the Digital Action Plan aim for an analogue switchover period commencing in 2010 to 2012, consistent with the targets set in many other industrialised nations and subject to the development of the roadmap," said Coonan's consultation document.
		Coonan's plans for digital television coincided with a consultation on a widespread shake-up in media ownership laws, relaxing limits on foreign media investment and the degree to which newspaper groups can also own radio and television stations.

	TLARK10: Digital Television
		Digital television is already in use in several locations all over the world, and it is well on its way in replacing the old fashioned analogue television systems.
		One scenario, purely in the television world, is that one station could broadcast several SDTV channels during the daytime and HDTV during prime time, thus being able to meet the special needs of the daytime viewers and provide high quality video during the most popular TV time.
		The interest for digital television in Europe has been growing fast for the last couple of years; in 1996, at the IBC Conference, a group called DIGITAG was established to "develop and harmonise digital terrestrial television internationally" [8].
