Television is a box-shaped device that can receive television signals and turn them into moving images on a screen with audio to its speakers. The devices are built in a transparent and photosensitive cathode. Signals are transferred to the transmitter from which they are sent to the recipients. The signals may, among other things, be captured by an antenna, a satellite dish (if there is satellite TV covers), or cables.
Each frame contains 288 lines for a total of 576 lines per full view, hence the term 576i used for comparisons between different television systems. In order to reproduce the surface, it is equipped with red, green and blue dots arranged in groups of three, but with such a relative position that the entire screen is covered. There are then three electron guns in the display tube, one for each color.
If the electrons from the blue cannon hits a blue dot, this action lights up the pixel. If a red, a blue and a green dot are next to each other, it shines with a certain brightness which the eye perceives as white. By mixing the three colors, most colors are rendered. This is called additive color mixing.
The pioneering semi-mechanical analogue system was demonstrated by John Logie Baird, who in January 27, 1926 could show a collection of scientists from the Royal Society how moving images were transmitted between two floors. A lot of other systems were invented afterwards, but Baird's was the most common. Mirror Room consisted of a spin with angled mirrors rotated rapidly.
But Charles Jenkins and Logie Baird's efforts were not met with any kind of respect. In fact, they faced derision and indifference to begin with. An article from the British newspaper, the British journal wrote that television was was a waste of time because you could not make money from it. But despite this, they continued their work, and in 1928 regular television broadcasts began. Not many years later the first television boom became a reality and thousands of viewers had now invested in a television or built a primitive one.
Analog broadcasting via terrestrial transmitters ceased in some countries and has been transferred to digital transmission. In order to receive a broadcast from a terrestrial transmitter you require a digital TV tuner. There are three different types of analog color television system: PAL, SECAM and NTSC. PAL is used in most of Europe, Africa, China and Australia.
Televisions have mainly been used to entertain, inform and educate. They brought visual news and information to a broad audience, this created some major developments in aspects such as propaganda and mind manipulation, where sublime messages were often used in advertising.
A television or electronic camera is a device that electronically receives motion pictures which are then transmitted directly to a TV receiver or stored on various media such as magnetic tape, DVD or hard drive. A camera is used mainly by professional broadcasters and can be seen as a precursor to the camcorder.
