How To Understand How Digital Televisions Work

Televisions are increasingly being manufactured in digital formats. Along with this development more and more TV broadcasting companies are also going digital. This, definitely, means that analog TV, which is the type that you may have watched your favorite shows on for decades, is already on its way out. However, you may still use your analog TV by installing a digital adapter on it so that it can still receive signals from digital TV channels. If you are keen on buying a new TV, make sure you get a digital television.

The most advantageous features you can get from a digital TV are better picture quality and you can access a larger number of channels. Another is that it can create an opportunity for an interface, making it an interactive television. These are the reasons why people prefer digital TV to their old analog TV. Since it may be an entirely new concept for you, it would be good if you get a basic background of how it works. The technical jargon may just confuse you, thus you must first get a basic understanding of the terms that you will meet. Afterwards, you may be able to comprehend the process in its simplest presentation. Here are the basics on how digital TV and its broadcasting work.

  1. Shows are shot in HDTV (high definition TV) format with the use of special equipment such as HDTV cameras. Once the taping or shooting is done, they are forwarded to the broadcasting and cable companies.
  2. The TV studio sends the show in signals to the digital satellite, which then transmits it to the cable company, the satellite TV provider, or to a local TV station.
  3. While the cable company uses fiber optics technology, such as that used on your phone and Internet lines, to deliver signals to your TV, the satellite TV provider or the local TV station use a digital transmitter to send signals.
  4. If you have a digital TV, you will naturally have digital reception either from your cable lines or from your antenna receiver. However, if your TV is not digital, then you may need a digital converter first, a device that would transform digital signals to analog.
  5. If you have an HDTV, then you will not need any digital converter as this is designed to accept signals in digital format. This can also serve as a card television, wherein you have an electronic card inserted to get a digital signal subscription from a provider just like what your SIM (subscriber identity module) does to your mobile phone.

There may be some difference in how cable companies and local TV stations transmit their signals depending on the technology they use. It is recommended that you ask your service provider how their system works so that you will get the basic information about your digital television.
