TV - A way of receiving and displaying
A television is a term for a terminal device for receiving television broadcasts (usually a special electronic device) on which people watch television broadcasts or CCTV broadcasts.
History
The first transmission of the image took place in 1926 in London. The Scotsman John Logie Baird is behind the success. In 1928, he carried out the first long-distance image transmission between London and New York. The first mechanical televisions were sold until 1934. After that, only electronic devices were sold.
In 1944, Baird introduced the first color electronic television for the first time.
The first television in Czechoslovakia was created in 1935 by associate Professor Jaroslav Shafranek
Method of reception and display
Previously (with the exception of the time of the creation of televisions and televisions), televisions used exclusively television screens with a classic cathode ray tube (CRT), later plasma screens and LCD (liquid crystal). Today, LED TVs (misleading designations; these are LCD TVs whose LCD panels are illuminated with white LEDs rather than CCFL lamps) and so-called "3D TVs" that can also display broadcasts and movies stereoscopically ("in three dimensions"). Modern TVs allow you to use a hybrid way of broadcasting HbbTV ("hybrid TV") and Internet access (the TV can be controlled using a keyboard and mouse connected to a USB port.). TVs allow you to communicate with a PC, view photos and videos stored in flash memory. TVs with an operating system (for example, Android), as a rule, have so-called Smart TV functions ("smart TV").
An integral part of every TV is an audio system. In the case of analog television, it is actually a radio receiver for receiving FM (frequency modulation), which receives a signal whose frequency differs (in our standard) by 6.5 MHz from the frequency of the video signal.
The paradox of modern types of (analog and digital) televisions is the relatively low sound quality (due to the thin profile) - televisions from the seventies or eighties of the twentieth century have a much higher sound quality (and, consequently, sound reproduction).
You can also connect other devices to play or record TV images and sound, such as a video recorder, video camera, DVD player, DVD recorder, digital camera, game console, hard disk, etc.
In addition, TV broadcasts can also be viewed on computer screens. In this case, it can be:
reception of a classical television signal (transmitted wirelessly or in cable television systems) using special equipment - TV cards ;
Internet broadcasting of a television signal - in this case, the signal is interpreted primarily using specialized software. Real free porn movies https://exporntoons.net online porn USA, UK, AU, Europe.
