Understanding digital broadcasting

For many years, television signals have been broadcast in analog format. Over the years, many countries around the world have started using digital broadcasting. The streaming format has a number of advantages.

Broadband– High definition and standard definition digital signals are divided into five signal patterns to accommodate multiple aspect ratios. This translates into good quality images for you, regardless of the size of the television you have.

Automatic tuning: signals are automatically tuned; therefore, you don’t have to worry about the bandwidth the signal is working on. Because of this, you can buy any television, be it LCD, plasma or any other and be sure that your television will be able to transmit the signals.

Numerous reception points: With digital transmission, you have many ways to receive the signal. The most common forms are: digital cable, satellite, DSL Internet connections, and mobile phone.

How does it work

This transmission reaches your television in the form of binary digits. These are computer signals that are made up of zeros and ones. When a television station broadcasts a program, the signal is taken from its audio and video format and compressed into a signal suitable for transmission.

The signal is then transmitted to a satellite space where it is sent back to the various television towers in your country. The towers then transmit the signal that is picked up by your television in your home.

Data levels

Digital broadcasters have three main data formats in which they can transmit signals. These formats include:

480: Provides standard definition television (SDTV) reception to your television. The signals are similar to analog signals.

720 and 1080– The format provides you with excellent video quality that you will find in high definition (HD). It is good to note that the 720 format offers 80% more pixels than SD, while the 1080 format offers more than 270% more dots to your TV.

Compression is a very important feature in digital transmission. It allows digital stations to send one or more subchannels on the same frequency. This allows you to receive many programs to watch.
