Television (TV) is a telecommunication medium for transmitting and receiving moving images that can be monochrome (black-and-white) or colored, with or without accompanying sound. "Television" may also refer specifically to a television set, television program, or television transmission.

The etymology of the word has a mixed Latin and Greek origin, meaning "far sight": Greek tele (τῆλε), far, and Latin visio, sight (from video, vis- to see, or to view in the first person).

Commercially available since the late 1920s, the television set has become commonplace in homes, businesses and institutions, particularly as a vehicle for advertising, a source of entertainment, and news. Since the 1950s, television has been the main medium for molding public opinion.^[1] Since the 1970s, the availability of video cassettes, laserdiscs, DVDs and now Blu-ray Discs have resulted in the television set frequently being used for viewing recorded as well as broadcast material. In recent years, Internet television has seen the rise of television available via the Internet through services such as iPlayer and Hulu.

In 2009 78 percent of the world's households owned at least one television set, an increase of 5% over 2003.^[2]

Although other forms such as closed-circuit television (CCTV) are in use, the most common usage of the medium is for broadcast television, which was modeled on the existing radio broadcasting systems developed in the 1920s, and uses high-powered radio-frequency transmitters to broadcast the television signal to individual TV receivers.

       HISTORY

In its early stages of development, television employed a combination of optical, mechanical and electronic technologies to capture, transmit and display a visual image. By the late 1920s, however, those employing only optical and electronic technologies were being explored. All modern television systems relied on the latter, although the knowledge gained from the work onelectromechanical systems was crucial in the development of fully electronic television.

The first images transmitted electrically were sent by early mechanical fax machines, including the pantelegraph, developed in the late nineteenth century. The concept of electrically powered transmission of television images in motion was first sketched in 1878 as the telephonoscope, shortly after the invention of the telephone. At the time, it was imagined by early science fiction authors, that someday that light could be transmitted over copper wires, as sounds were.

The idea of using scanning to transmit images was put to actual practical use in 1881 in the pantelegraph, through the use of a pendulum-based scanning mechanism. From this period forward, scanning in one form or another has been used in nearly every image transmission technology to date, including television. This is the concept of "rasterization", the process of converting a visual image into a stream of electrical pulses.

In 1884, Paul Gottlieb Nipkow, a 23-year-old university student in Germany,^[5] patented the first electromechanical television system which employed ascanning disk, a spinning disk with a series of holes spiraling toward the center, for rasterization. The holes were spaced at equal angular intervals such that, in a single rotation, the disk would allow light to pass through each hole and onto a light-sensitive selenium sensor which produced the electrical pulses. As an image was focused on the rotating disk, each hole captured a horizontal "slice" of the whole image.^[6]

Nipkow's design would not be practical until advances in amplifier tube technology became available. Later designs would use a rotating mirror-drum scanner to capture the image and a cathode ray tube (CRT) as a display device, but moving images were still not possible, due to the poor sensitivity of the selenium sensors. In 1907, Russian scientist Boris Rosing became the first inventor to use a CRT in the receiver of an experimental television system. He used mirror-drum scanning to transmit simple geometric shapes to the CRT.^[7]

Vladimir Zworykindemonstrates electronic television (1929).

Using a Nipkow disk, Scottish inventor John Logie Baird succeeded in demonstrating the transmission of moving silhouette images in London in 1925,^[8]and of moving, monochromatic images in 1926. Baird's scanning disk produced an image of 30 lines resolution, just enough to discern a human face, from a double spiral of Photographic lenses.^[9] This demonstration by Baird is generally agreed to be the world's first true demonstration of television, albeit a mechanical form of television no longer in use. Remarkably, in 1927, Baird also invented the world's first video recording system, "Phonovision": by modulating the output signal of his TV camera down to the audio range, he was able to capture the signal on a 10-inch wax audio disc using conventional audio recording technology. A handful of Baird's 'Phonovision' recordings survive and these were finally decoded and rendered into viewable images in the 1990s using modern digital signal-processing technology.^[10]

In 1926, Hungarian engineer Kálmán Tihanyi designed a television system utilizing fully electronic scanning and display elements, and employing the principle of "charge storage" within the scanning (or "camera") tube.^{[11][12][13][14]}

On 25 December 1926, Kenjiro Takayanagi demonstrated a television system with a 40-line resolution that employed a CRT display at Hamamatsu Industrial High School in Japan.^[15] This was the first working example of a fully electronic television receiver. Takayanagi did not apply for a patent.^[16]

By 1927, Russian inventor Léon Theremin developed a mirror-drum-based television system which used interlacing to achieve an image resolution of 100 lines.^[17]

Philo Farnsworth

In 1927, Philo Farnsworth made the world's first working television system with electronic scanning of both the pickup and display devices,^[18] which he first demonstrated to the press on 1 September 1928.^[18][19]

WRGB claims to be the world's oldest television station, tracing its roots to an experimental station founded on 13 January 1928, broadcasting from the General Electric factory in Schenectady, NY, under the call letters W2XB.^[20] It was popularly known as "WGY Television" after its sister radio station. Later in 1928, General Electric started a second facility, this one in New York City, which had the call letters W2XBS, and which today is known as WNBC. The two stations were experimental in nature and had no regular programming, as receivers were operated by engineers within the company. The image of a Felix the Cat doll, rotating on a turntable, was broadcast for 2 hours every day for several years, as new technology was being tested by the engineers.

At the Berlin Radio Show in August 1931, Manfred von Ardenne gave the world's first public demonstration of a television system using a cathode ray tube for both transmission and reception. The world's first electronically scanned television service then started in Berlin in 1935. In August 1936, the Olympic Games in Berlin were carried by cable to television stations in Berlin and Leipzig where the public could view the games live.^[21]

In 1935, the German firm of Fernseh A.G. and the United States firm Farnsworth Television owned by Philo Farnsworth signed an agreement to exchange their television patents and technology to speed development of television transmitters and stations in their respective countries.^[22]

On 2 November 1936, the BBC began transmitting the world's first public regular high-definition service from the Victorian Alexandra Palace in north London.^[23] It therefore claims to be the birthplace of television broadcasting as we know it today.

In 1936, Kálmán Tihanyi described the principle of plasma display, the first flat panel display system.^[24][25]

Mexican inventor Guillermo González Camarena also played an important role in early television. His experiments with television (known as telectroescopía at first) began in 1931 and led to a patent for the "trichromatic field sequential system" color television in 1940.^[26]

Although television became more familiar in the United States with the general public at the 1939 World's Fair, the outbreak of World War II prevented it from being manufactured on a large scale until after the end of the war. True regular commercial television network programming did not begin in the U.S. until 1948. During that year, legendary conductor Arturo Toscanini made his first of ten TV appearances conducting the NBC Symphony Orchestra,^[27] and Texaco Star Theater, starring comedian Milton Berle, became television's first gigantic hit show.^[28] Since the 1950s, television has been the main medium for molding public opinion.^[1]

Amateur television (ham TV or ATV) was developed for non-commercial experimentation, pleasure and public service events by amateur radio operators. Ham TV stations were on the air in many cities before commercial TV stations came on the air.^[29]

In 2012, it was reported that television revenue was growing faster than film for major media companies.^[30]

       differences

  The way the television is made has changed drastically since the first model was made. The first telecsion was made on March 28, 1928 by John L. Baird, a scientist from Britain. He first called it a sight machine (Wilt). He pioneered the way electronics are built into making televisions today. The earlier models had a black and white resolution showing through a very small screen. They had speakers already built in and were framed with wood casings. Only a few stations would be available. Since then the innovations companies such as sony, rca, panasonic and others have made have changed the entire aspect of the way the television is made and watched. Cable was introduced to widen the variety of channels to watch. The models of televisions began getting thinner and screens began getting larger. The quality of the picture has evolved from black and white to color, and from color to and even more vivid picture when lcd screens and now even led screens were introduced. There has also been accessories put onto televisions to enhance the picture and sounds, such as high definition and surround sound systems. We have exposed in the world, plasma tvs, lcd and led tvs. Plasma screen televisions use a sheet of individual plasma cells that generates a picture when electric charge is applied ("The Skinny Behind LED Flat Screens"). LCD tvs use a liquid crystal compressed between two glass plates. an image is created when electricity is applied to the crystals. LED tvs are made the same way except they use a blacklight instead of using flourescent lamps. As of this moment the most popular televisions out in circulation are LED televisions ("The Skinny Behind LED Flat Screens"). They are so versatile and can be put anywhere because they are so thin and dont take up any space. These tvs also have a spectacular picture because they allow brighter contrast and deeper blacks than flourescent LCD televisions.

cricket

                     cricket          

cricket is a bat-and-ball game played between two teams of 11 players on a field at the centre of which is a rectangular 22-yard long pitch. Each team takes it in turn to bat, attempting to score runs, while the other team fields. Each turn is known as an innings.

The bowler delivers the ball to the batsman who attempts to hit the ball with his bat far enough for him to run to the other end of the pitch and score a run. Each batsman continues batting until he is out. The batting team continues batting until ten batsmen are out, at which point the teams switch roles and the fielding team comes in to bat.

In professional cricket the length of a game ranges from 20 overs of six bowling deliveries per side to Test cricket played over five days. The Laws of Cricket are maintained by the International Cricket Council (ICC) and the Marylebone Cricket Club (MCC) with additional Standard Playing Conditions for Test matches and One Day Internationals.^[1]

Cricket was first played in southern England in the 16th century. By the end of the 18th century, it had developed into the national sport of England. The expansion of the British Empire led to cricket being played overseas and by the mid-19th century the first international matches were being held. The ICC, the game's governing body, has 10 full members.^[2] The game is most popular in Australasia, England, the Indian subcontinent, the West Indies and Southern Africa.

ramayna

It was painful to read the news on 13-9-2007 that the central Govt. of India submitted an affidavit in the Supreme court that there was no historical and scientific evidence to establish the existence of Rama and the Ramayana. The Archaeological survey of India stated that the contents of the Valimiki Ramayan cannot be a historical record, because there is no proof to the characters and events, depicted therein.

            This statement is agonizing because there is ample evidence in the Valmiki Ramayana to prove that it is history. I say so because I have studied the Valmiki Ramayan for many years and have done lot of research on it.

            Valmiki was contemporary to Rama and he wrote the history. He says at 1-3-9 that he searched for the information and then wrote the history. When Seeta was abandoned by Rama, she came to Valmiki’s hermitage. Therefore Valmiki could gather a lot of information from her. In spite of this statement, if the Govt. does not want to believe, then how could it believe in the existence of Jesus and Mohamad Paigambar? Why the Govt. declared holiday on the birth date of Mohamad, which is not known to any book, historical or other.

            The Ramayana is a true history, therefore Valimiki has given 73 ancestors of Rama and recorded which Prince married which princess. The ancestry of Rama and Seeta both is recorded by Valmiki. It is not so in case of Jesus and Paigambar. Even then the Govt agrees with them and not with Rama. Why?

            If Rama was an imaginary character how should he be referred to by hundreds of books for hundreds of years? The imaginary characters are not at all referred to by other books. For example, Tarzan and Sherlock Homes are not at all referred to by other authors. The generators of those characters have not mentioned even the father and mother of their heroes. It is not the case with Rama and Seeta.

            Seeta is referred to again and again, place to place, even in Lanka, which is at least 1500 miles away from the residence of Rama and Valmiki. Many places in Shri Lanka bear the names connected to Seeta. There is a place called as ‘Diwurungaha’ in Lanka, which means the tree, where Seeta took an oath of chastity. Why all historical stories are told in Shri Lanka? Only because, they are true historical facts.

            In search of Seeta, Vanaras went to the east. Sugreeve told them to search for Seeta to the end of the east, which is demarcated by a golden, three branched, Tala tree, which shines from the top to bottom, carved on Uday Mountain. Kishkindha 40/53,54 describes this Tala tree having three branches. Valmiki wrote this true fact around 7292 years BC, and after 1965 AD such a three branched tree is discovered in the South America, on an offshoot of Mount Andes, near the Bay of Pisco. It is 820 feet tall, has three branches and it glitters like gold, when seen from the sky. Does this discovery not prove the Ramayana, authored by Valmiki, as true history? This one evidence alone is sufficient to prove the Valmiki Ramayana as true history.

            Tulasi Ramayana is not a history, it is written in devotion, 7700 years after Rama’s demise. I have proved by astronomical mathematics that Rama’s birth date is 4^th December 7323 BC. He married to Seeta on 7^th April 7307 BC. Rama was to be coroneted on Thursday, 29th November 7306 BC, but had to go in to exile. Rama fought with Ravana from 3^rd November 7292 BC to 15^th Nov. 7292 BC. On Phalgun Amavasya, on 15^th Nov. 7292 Rama killed Ravana. Valmiki has recorded Thursday and calculations show that it was the Thursday on 29^th Nov. 7306 BC. This proves the Valmiki Ramayana has a true history.

            Hanuman entered Lanka on1st Sept. 7292 BC and returned with information of Seeta on 3^rd Sept. Rama moved his army to the south on 2^nd October, reached the south sea on 22nd Oct. Nala built a temporary bridge in 5 days from 26^th to 30^th Oct. 7292 BC. Rama-Ravana war took place from 3^rd Nov. to 15^th Nov. 7292 BC. On 15^th Nov. Phalguna Amavasya Rama killed Ravana. I have discovered the dates of almost 45 incidents from the Valmiki Ramayana. I used astronomy, which is a science.

            Around Delhi it is supposed that Rama killed Ravana on Vijaya Dashami; this is absolutely wrong. Valmiki has clearly stated that it was Amavasya. (Yudh 92/64)

            The Govt. depended on Archaeology, which is not a perfect science. During 1971, when I showed that Dinosaurs were present around Dwaraka during the Mahabharata era, around 5561 BC., the Archaeologist laughed at me saying the Dinosaurs never existed in India. But now existence of dinosaurs is well proved near Ahemedabad. Archaeologists did not approve my date of 5561 BC for the Mahabharata and 7323 BC for the Ramayana. They opined that there was no culture in such a remote past. But now a well-developed city is found submerged under the sea, in the Bay of Cambay, near Gujarath, which has water and drainage systems. It proves that the opinions of the Archaeological Survey are not believable.

            It is true that the Rama Setu never existed. Valmiki calls it Nala Setu, so also Vyasa in the Mahabharata calls it Nala Setu. It was erected by one engineer Nala. Valmiki has written in clear words that Nala erected the Setu using trees. Valmiki never says that the rocks floated on water. On the contrary he states that big rocks were cut with machines and thrown in to the sea, which sank and on that foundation a Setu of wood was built. Valmiki wrote a true history, but later it was perverted by devotional writings like that of Tulasidas, in the 15^th century AD.

            Valmiki is keen to state the sea, there, was shallow and so boats could not go in to the sea. Today it is proved that the sea is shallow, proving the Ramayana as true history. How could Valmiki at least 1500 miles distant from the south sea write so exactly? Because he wrote history after gathering information from Hanuman, Seeta, Rama etc. Those were true characters

            The Govt should not say that the Ramayana is not a history and Rama never existed. There is no evidence to say that. BJP, VHP, and others should also not say anything untrue. Why should they say it as Rama Setu? Why should they hold that the Setu was built with stones? Why should they suppose that the stones floated on water? It is all false. Valmiki was a truth abiding sage. He wrote the truth and truth only. Hindu should stick up to the truth.

            The true fact is that there was a row of rocks, which made the sea shallow. Nala intelligently filled up the gaps in that row, with wood and made a temporary bridge. It was prepared 9299 years ago. How can it be present now? What is present is a natural row of rocks, which can be safely broken to prepare a way for ships. That way will save lot of fuel, time and money. It should be done. Nobody should oppose it and obstruct the national benefit. The Govt. too should avoid talking nonsense. The Govt. should abide by the truth. Rama was a true historic person and Valmiki has written a true history, though he used the form of poetry.

            I am ready to help the Supreme Court and the Govt. to show the truth. I have already published a book in Marathi, “Vastava Ramayana”, which shows the true historicity of the Ramayana, fixing the dates of almost 50 incidents in Rama’s life.
