Television
The television set is evidently the most important and popular electronic product of all time. All homes in developed countries have one or more TV sets and in many countries there are considerably more TV sets than telephones.
But in 1939 at the World’s Fair in New York a tiny nine-by- twelve inch box was the centre of attention for hundreds of people. They were the first to see a television set in action. Compared to today’s TV shows of underwater and outer-space research, those first black-white pictures were not very good. The pictures were only transmitted from one side of the Fair territory to the other. But in 1939 they were of historical importance.
Within a few days the news of television spread throughout the world. A lot of people wanted to have a look1 at the new invention. Everyone was interested in it. But only few people owned television sets in the next few years. When World War II broke out2 electronic factories that began the TV production stopped making them and started making war materials instead. When the war was over, TV sets began coming off factory assembly lines. By 1958 there were millions of them.
In a surprisingly short time people watched fewer films and turned from newspapers and magazines to TV. In its short history television has had great influence on people’s life and way of thinking. Rocket-launching, concerts and football and tennis matches can be seen direct as they occur. The boundaries of time and space have disappeared.
At present TV communication is provided with the help of a system of artificial earth satellites so that people living in different parts of the country and all over the world and in different time zones are able to watch the central TV programs at the most convenient hours.
Nowadays many countries also have cable TV, a system using wires for the transmission of television programs (like telephone calls). Cable television first appeared in 1949 as a means of transmitting TV signals to rural and mountain areas far from big cities. Cable television’s next big step forward was made by the mid — 1980s. Scientists announced that many technical problems had
been solved and in the future it would be possible via satellite and cable TV to use more channels on a TV set at every home in the world.
Then we saw how a new technical invention, colour television, was rapidly replacing black-and-white television. Recently it was reported that the first pocket-size3 colour television set had been developed. It was stated that a liquid-crystal display4 was used similar to those on calculators and watches and that it weighed less than a pound.
A few years ago it became evident that the next major advance for TV would be digital television. In a digital system the usual continuous signal is replaced by a digital code containing detailed information on brightness, colour, etc. A digital TV set hangs on the wall like a picture. Essentially, it is a minicomputer with a visual display. Once a week5 you put the programs you like into the memory, and the TV set will automatically switch on the desired channel at the right time. You can watch several programs simultaneously on miniscreens and then produce one of them in full format. Also, the TV set can automatically video-record the programs when you are absent or occupied.
By the end of 1980s television has moved to a new and the most important stage in its development since the appearance of colour television. Technically it is called high-defmition television (HDTV)6 or Hi-Vision. This is the much higher resolution television7 of the 21st century. This revolution was started by Japanese manufacturers when they developed a new video system with a picture resembling a wide-screen film more than traditional television. The new system increases the screen’s width-to-height ratio8 (16:9). The result is a picture several times sharper than in the existing TV sets. Besides, recent developments in plasma display panel technology9 make HDTV commercially practicable. The plasma display makes it possible to produce a large, bright, colour, flat TV screen so thin and light that it can also be hung on a wall like a framed picture. The engineering problem that has existed almost since the first days of television may be solved now.
Телевидение
Телевизор-это, видимо, самый важный и популярный электронный продукт всех времен. Все дома в развитых странах имеется один или несколько телевизоров и во многих странах есть значительно больше телевизоров, чем телефоны.
Но в 1939 году на Все-мирной выставке в Нью-Йорке крошечный девять на двенадцать дюймов поле было центром внимания, сотни людей. Они были первыми, чтобы посмотреть Телевизор в действии. В отличие от сегодняшних телевизионных шоу, подводных и космических исследований, те первые черно-белые фотографии были не очень хорошими. Фотографии были переданы только из одной части территории Ярмарки на другую. Но в 1939 году они имели историческое значение.
За несколько дней весть о телевидении и распространилось по всему миру. Многие люди хотели иметь смотреть 1 на новые изобретения. Каждый был заинтересован в этом. Но только немногие люди владели телевизором в ближайшие несколько лет. Когда вторая Мировая Война сломала out2 электронные заводы, которые начали Телевизор производство было остановлено, делая их, и стал делать материалов вместо войны. Когда война закончилась, телевизоры стали приходить включая сборочной линии завода. К 1958 их были миллионы.
В удивительно короткое время люди смотрели меньше фильмов и отвернулся от газеты и журналы, телевидение. В своей короткой истории телевидение оказало большое влияние на жизнь людей и способ мышления. Запуск ракет, концерты и футбольные и теннисные матчи можно увидеть прямой, как они происходят. Границы времени и пространства исчезли.
В настоящее время телевидение связь обеспечивается с помощью системы искусственных спутников земли, чтобы люди, живущие в разных частях страны и во всем мире, так и в разных часовых поясах имеют возможность смотреть центральных ТВ-программ в наиболее удобное время.
В настоящее время во многих странах также есть Кабельное телевидение, системы с помощью проводов для передачи телевизионных программ (таких, как телефонные звонки). Кабельное телевидение впервые появились в 1949 году в качестве средства передачи ТВ-сигналов в сельских и горных районах, далеко от больших городов. Кабельное телевидение-это следующий большой шаг вперед был сделан в середине 1980 - х годов. Ученые объявили, что многие технические проблемы
не была решена и в будущем это будет возможно через Спутниковое и Кабельное телевидение использовать несколько каналов на ТВ в каждый дом в мире.
Затем мы увидели, как новое техническое изобретение, цветной Телевизор, стремительно замена черно-белого телевидения. Недавно сообщалось, что первый pocket-3 цветной Телевизор был разработан. Он заявил, что жидкость-кристалл display4 использовали похожие на калькуляторы и часы, и весил он меньше фунта.
Несколько лет назад стало очевидно, что следующим важным шагом вперед для ТВ будет цифровое телевидение. В цифровой системе обычного непрерывный сигнал заменяется цифровой код, содержащий подробную информацию о яркости, цвета и т.д. Цифровой Телевизор висит на стене как картина. По сути, это миникомпьютер с визуальным отображением. После week5 вы ставите программы вы любите в памяти, и Телевизор будет автоматически переключаться на нужный канал в нужное время. Вы можете посмотреть несколько программ одновременно на miniscreens и затем произвести одну из них в полный формат. Также Телевизор может автоматически видео-запись программ, когда вы отсутствуете или оккупации.
К концу 1980-х годов телевидение переехал в новый и самый важный этап в своем развитии с появлением цветного телевидения. Технически это называется high-defmition (HDTV)6 или Hi-Vision. Это гораздо более высоким разрешением, television7 21-го века. Эта революция была начата японских производителей когда они разработали новые системы видео изображение, напоминающее широкоэкранный фильм больше, чем традиционного телевидения. Новая система увеличивает экрана ширина / высота ratio8 (16:9). В результате получилась картинка несколько раз острее, чем в существующих телевизоров. Кроме того, последние события в плазменная панель technology9 сделать HDTV коммерчески оправданной. Плазменный дисплей позволяет производить большой, яркий, цветной, телевизором с плоским экраном; он настолько тонкий и легкий, что его также можно повесить на стену, как картину в раме. Инженерная проблема, которая существовала практически с первых дней ТВ может быть решена и сейчас.

Recently it was reported in the press that the USA was trying to build bigger, better and much more expensive TV sets. Experts declared that it was the most important change in television since the invention of colour television. They informed that a new kind of television had images so clear that watching it was like looking through a window.
But it became known that Japanese specialists had started their work on HDTV when nobody else in the world was thinking how to improve TV. The inventors expected that their standard for high-definition television would be used throughout the world. However, the Europeans have announced that they would set their own standard. And now it is not clear whether the Japanese standard will be used or not. Some people consider that a single high-definition TV standard will allow to exchange news and may bring nations together.

A Letter to a Sweetheart.
A young man was writing a letter to his sweetheart (любимая) who lived just a few miles away in a nearby town. He began to tell her how much he loved her and how wonderful he thought she was. But the more he wrote, the more poetical he became. Finally, he said that in order to be with her he would suffer the greatest hardships (лишения), he would face the greatest dangers (опасность) that anyone could imagine. In fact, to spend only one minute with her, he would climb (подниматься) the highest mountain, he would swim the widest river, he would fight the fiercest (свирепый) animals. He signed his name, and then suddenly remembered that he had forgotten to mention something rather important. So, in a postscript below his name, he added: «By the way, I’ll be over to see you on Wednesday night — if it doesn’t rain».
A Frenchman in England
A Frenchman was once travelling in England. He could speak English quite well but not perfectly. His vocabulary was not large.
Once, for example, he was eating in a small country inn (гостиница) and he wanted to order some eggs. But he couldn’t remember the word for eggs.
Suddenly, through the window, he saw a rooster (петух) walking in the yard. He immediately asked the waiter what the bird was called in English. The waiter told him that it was called a rooster. The Frenchman then asked what the rooster’s wife was called. The waiter told him that she was called a hen. The Frenchman then asked what the hen’s children were called. The waiter told him that they were called chickens. The Frenchman then asked what the chickens were called before they were bom. The waiter told him that they were called eggs. «Fine!», said the Frenchman, «Please bring me two plus a cup of coffee and some toast.»

Telegraph
Benjamin Franklin, an American who is famous for his interesting and useful inventions, published his ideas about electricity in 1752. Scientists in many countries became interested in this wonderful form of energy. They wanted to find the answer to a very important question: could the electricity be used to develop a fast, efficient system of long-distance communication? Experiments proved that electricity could travel instantly over a very long piece of wire. But a note that was written on a piece of paper couldn’t be put into a wire. How could electricity be used to send a message? A Danish scientist discovered that electricity could move a needle from left to right and that the needle could be pointed at letters on a piece of paper. Then a German government worker made up a code system that could be used with an electric needle. In 1837 two English scientists sent a message by electric telegraph for a distance of more than 1.6 kilometers.
Samuel Morse, an American portrait painter, was experimenting with an electric telegraph too. At first he connected a pencil to an electric wire. When the electricity came through the wire the pencil made wavy lines. Then Morse invented a code that used dots and dashes for the letters of the alphabet. Finally, he discovered that telegraph messages did not have to be written, they could be sent in sound.
On May 24, 1844, the first long-distance message was sent by telegraph for 64 kilometers.
Telegraph companies were formed in many cities. By 1861 telegraph wires stretched from the Atlantic to the Pacific. In Europe too, Samuel Morse’s system became popular.
But telegraph wires couldn’t be hung over an ocean. Messages to and from Europe had to be sent by ship — a journey of two or three weeks. A new method was needed.
The Atlantic Telegraph Company which was organized in 1856 wanted to try to lay a cable on the floor of the Atlantic Ocean. The 4,ООО-kilometer cable broke three times. Each time a new cable had to be made. Finally, on July 27, 1866, the first transatlantic message was sent from Newfoundland to Ireland.
Later cables were laid to Central and South America. After 1900 transpacific cables were laid to Asia and Australia. At last news and business information could be sent instantly to almost every country in the world.

Alexander Graham Bell never planned to be an inventor, he wanted to be a musician or a teacher of deaf people (глухих). The subjects that he studied at school included music, art, literature, Latin and Greek. They did not include German which all scientists used in their books. Alexander’s mother was a painter and a musician. His father was a well-known teacher of deaf people.
When Alexander was only sixteen, he became a teacher in boy’s school in Scotland. He liked teaching there, but he still wanted to become a teacher of deaf people as his father.
He read all the books about sound that he could find and started to work on some of his own experiments.
At twenty five Alexander became interested in finding a way to send human voice through an electric wire. The parents of his pupils contributed money for the equipment. He found an assistant, Tom Watson, who worked in an electrical shop. For two years Tom and Alexander were working together to build a machine that people could use to talk to one another over long distances. After two years, the two young men were becoming discouraged (опустились руки). Then, one day, when they were working on a new transmitter Alexander spilled some acid (пролить кислоту) on himself. Tom Watson, who was alone in another room, heard a voice. The voice was coming through a wire to a receiver on the table! The voice was Alexander Bell’s! It was saying: «Come here, Mr. Watson. I need you!»
The first telephone line was built in Germany in 1877. By 1915 a telephone line was opened in the United States — 5,440 kilometers from New York to San Francisco.
Now design bureaus all over the world are conducting experiments to develop video-phone or picture phone. A young man in Moscow wants to speak to his friend in Vladivostok. He lifts his telephone receiver, dials a number. After a very short time his friend answers. As he picks up his receiver, his picture appears on the screen. They can speak to each other face to face because they are using a new kind of telephone which may be called «a video-phone». In addition to the usual telephone, the equipment includes a small television screen (14 cm by 13 cm) and, combined with the screen, a television camera. The camera tube will allow the user to switch from a wide view of the room to the face of the person speaking. The focus can be changed to give clear pictures of objects 0.3,0.9 and 6.0 meters away from the camera. There is also a mirror attachment, which allows the camera to scan documents which may be lying on the table. The camera adjusts itself automatically to different lighting conditions.

Talking via Space
Communication has come a long way from the time when an Indian beat a drum (барабан) in the forest to the time when a scientist receives messages from a satellite. In this space age communication has become a highly developed field. The system of communica-tion in large countries is unthinkable today without space satellites. Besides large distances, there is a great time difference: the territories of some countries comprise up to 11 zones. Satellites help to minimize all the difficulties that may appear. They rapidly transmit TV and radio programs to different towns, cities, and distant areas.
Space systems and electronic technology have made it possible to set up an automatic system of communication designed for rapid transmission of all kinds of information.
People write letters and send telegrams. But at the same time people living in various cities like to exchange (обмениваться) news on the telephone. Statistics reports that the number of longdistance telephone calls is about 2, 000 million per year. A person in Moscow talking on the phone with Vladivostok must know that this conversation is carried on through a satellite.
Trains and cars can use mobile radio telephones to make calls. Businessmen can use fax machines which provide electronic transmission of documents and messages over telephone lines. Even photographs can be sent and received over telephone wires.
Practically all the population in large countries can watch TV via satellites. The orbital communication systems make it possible for people from different continents to see and hear one another.
The importance of space means of communication is increasing every year. The communication satellites of the international organization «INTERSAT» enable people to keep reliable telephone, telegraph, telex and fax communication in any weather with ships practically in every part of the World Ocean.
