The technology of transmitting images and sound over a distance was not always known to people. Television came to the homes of people abroad in the early 50s of the 20th century, and in the Soviet Union at the end of the 60s. It has gone through many changes since then. Now almost every mobile phone has its own television. What is television? Let's figure it out.

Television definition

Television is a complex Greek word, literally meaning "I can see far." Television is a method of transmitting and receiving moving or still images and soundtrack over a distance by means of electrical and radio communications. The basic principle is to encode the elements of images and sounds into a sequence of electrical signals. Further, these signals are transmitted via communication channels to the receiving point, from where they are returned converted. We see the finished “picture” on TV.

  • the field of science, technology and culture associated with the transfer to a distance of moving objects by means of electronic devices;
