For many years, television signals have been transmitted in analog format. Over the years, many countries around the world have started to use digital broadcasting. The streaming format comes with a number of benefits.
Profits
broadband: High definition and standard definition digital signals are divided into five signal patterns to accommodate multiple aspect ratios. This translates to good quality images for you, no matter what size TV you have.
automatic tuning: signals are automatically tuned; therefore, you do not have to worry about the bandwidth in which the signal works. 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.
Many 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 telephony.
How does it work
This transmission arrives at 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 form and compressed into a signal that is suitable for broadcast.
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 your TV picks up into your home.
data tiers
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 TV. The signals are similar to analog signals.
720 and 1080: The format gives you the excellent video quality you 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 270% more dots to your TV.
Compression is a very important feature in digital transmission. It allows digital broadcasters to send one or more subchannels on the same frequency. This allows you to receive many programs to watch.
Conclution
Here’s what you need to know about digital streaming. As a consumer, you are not concerned with the technical aspects of digital transmission. All you need to do is buy a TV or set-top box that is compatible with the signals. As a general rule, you should make sure you buy from a reputable store.
