Did you know: Today is the world TV day

Today is the day of World Television, going back in time, returning to the late 19th century and early 20th century to learn about the stories surrounding the history of the first human television.

1. What is television?

Television is a technology in the field of telecommunications and electronics, it includes a collection of electronic devices. Capable of receiving radio signals as well as transmitting electrical signals carrying encrypted images and sounds, transmitted as radio waves or via fiber-optic systems, or coaxial cables.

Television meets both audio and visual functions at the same time, images will be shown on screens and sounds played on the speaker system. Television is in English as Television, in addition to other names such as Television, Television or more concise is from television.

The world still knew John Logie Baird was the inventor of the first TV in 1925. However, the origin of the TV was far and more complicated.History shows that a German student Paul Gottlieb Nipkow was the first to introduce the first electronic mechatronic system in 1885.

Nipkow's turntable design is considered to convert images into grading points. But it was not until 1907, the invention of the new magnification tube technology helped the designs come true. At that time Constatin Perskyi proposed from TV in a publication at the International Electronics Institute at the International Fair in Paris on August 25, 1900.

Philo Farnsworth, an American (born in 1906) launched the first TV in 1927. However, his invention not recognized by the American Radio Association (RCA) and must be debated for a long time. Newly recognized TV copyright belongs to themselves.

In 1924, British scientist Bellde succeeded in transmitting and receiving images, making images that could be transmitted over long distances, pioneering the use of satellite TVs later on. .

In 1926, in London, he performed publicly on this experiment that surprised the world. Although the TV he studied produced only two colors black and white and the image was very fuzzy, but the opening of the TV later. And Bellde is honored as "the ancestor of TVs".

3. The first color TV

The world's first color TV was invented by John Logie Baird in 1925. John Logie Baird was a Scottish inventor. He was the first to introduce color television technology using electronic light bulbs, placing a very important milestone in the development history of television technology.

The presentation for Logie Baird's first color TV took place in 1928. This TV could run 30 frames in 5 seconds, then improved to 12.5 frames per second and John Logie Baird became the most successful person for the TV and television industry at the moment.

4. First television show

In 1926, the first television show was broadcast by John Logie Baird. This is a puppet dance performed by John Logie Baird from a series of cameras and sent to images from a nearby TV screen.

By 1928, Baird first broadcast a radio program abroad, from London to New York. This is considered the first color television broadcast in the world.

5. When did the first commercial TV come into being?

The world's first commercial television model.

The commercial TV was first launched in the US in 1938 named Dumont Model 180. The 8x10 inch screen-sized TV was sold for 395 USD at that time, equivalent to nearly 7000 USD at the time. present.

6. What year was the remote control invented?

Currently, the TV must have remote control is obvious. However, nearly 30 years after the first TV came out, new TV controls were invented. In 1955, Eugene Polley and his colleague Robert Adler invented the remote control for the TV.

When it was first introduced, this device was named 'Flash-Matic', which used to interact with the TV through the photoelectric effect. It gradually replaced popular cable-connected control devices at that time. In 1997, Polley and Adler's remote inventions were awarded the Emmy award of the American TV Academy.

7. The first professional television program

On November 2, 1936, from Alexandra Palace Victoria Palace in northern London, for the first time the BBC broadcast the first professional television, marking the start of world television. According to data left, there were only about 500 TVs caught by this program at that time.

At that time, BBC used two systems to signal, Baird 240 lines and Marconi-EMI 405 lines. However, after 6 weeks of alternating testing, the Baird system revealed its disadvantages. It's too cumbersome and the effects are inferior to Marconi-EMI. Therefore, Baird was removed in early 1937.

In November 1937, the BBC made its first notable outdoor broadcast. It was the broadcast of the coronation ceremony of King George VI at Hyde Park, London. BBC used a portable transmitter placed on a special car. Thousands of spectators witnessed this broadcast.

8. How many TVs were sold in the world

Until now, it was impossible to estimate how many TVs were sold in the world. However, according to statistics, in 2013, 79% of households in the world own at least 1 TV.

9. People 's attitude when watching the TV first

When it was first released, the TV was a wonderful world for viewers at that time. For the first time when color TV was introduced at the World Fair held in 1964 in New York City (USA).

In order for customers to experience the advantages and advantages of color TV compared to black-and-white TV, the owner of color TV shop has invited customers to record and take pictures directly 'at the match'. And it was recorded the emotional moments of the first people watching color TV, from surprise, excitement to shock, panic and booing.

The reaction of the guests was very interesting, the owner of the shop then recorded these precious moments, at that time, the color TV for everyone was still a new and remarkable invention. amazing.

10. A moment of world television history

Television recorded the event on January 20, 1969 when the American astronaut and Apollo 11 spacecraft put their first steps on the moon.

In the 60s of the twentieth century, television became an important means of entertainment in the life of mankind, this technology has brought to people an extremely interesting experience in spiritual life.

And the television recorded the golden mark of the event in an event of the great world, that was the event on January 20, 1969 when American astronaut Neil Armstrong and Apollo 11 spacecraft set The first step to the moon, that historic moment has entered the hearts of millions of people across the United States and the world through the television system.

Memorable milestones of television

1885: Paul Gottlied Nipkow, a German student created the first electromechanical TV system, which included rotating and converting images into points. But that design was only really successful after the contribution of the magnification tube technology. And now the TV still stops at showing still images.

1911: Two Russian scientists Boris Rosing and student Vladimir Kosma Zwongrykin successfully built a television using a mirror-shaped mirror to screen, the unfinished project, Boris Rosing was imprisoned by Stalin and died. 2 years later.

1920: American scientists Charles Francis Jenkins and John Logie Baird created the first complete television model of mankind.

1927: A young American scientist named Philo Taylor Farnsworth, developed into cathode ray tube, an important invention in electronic signaling. This invention is considered a major breakthrough in human television technology.

1930: Considered the beginning of the era of television with the introduction of commercial TVs such as EMI-Marconi and Baird with two 240-scan signaling systems and 405 scanning lines.
