How does TV broadcasting work?

The television has changed human lifestyle but there is a lot that goes into getting that channel on your television set.

With the digital age, the set top box has become common in every house hold. In India the concept of cable is going away with satellite television acting as a replacement. But how does this satellite technology work?

The satellite and the set top box are the two most important components in TV broadcasting. The channels are sent to satellites via broadcasting companies. The satellite receives the data in analog format. The satellite sends the signals received from broadcasters to all the viewers or customers. The signal received at home is in digital format that is converted into picture by the television. The dish antenna captures the signal and sends it to the set top box that is basically an analog to digital converter. The television takes this binary data and converts it into RGB or red, green And blue colors to create the picture you want to see.

That was for modern televisions but CRT televisions had a different working principle. The CRT televisions would receive analog signals directly into the television. The CRT or cathode ray tube generates a voltage that is very high. A film between the screen and the CRT would create the RGB colors and you would get to see your favourite shows. There were too many problems with CRT's bad picture quality and higher requirement of servicing. Not to forget they were big and heavy too which is why they were replaced.

This was a very brief working of TV broadcasting. The entire procedure is too boring and frankly very boring to read. Hopefully this answers your question.
