What is digital television?

Digital TV, also called DVB (Digital Video Broadcast), is a digital way to receive television channels on your TV. In the past, TV channels were transmitted analog, via cable, to the living room. Today cable companies also broadcast digital signals. The advantage of digital television is that the chance of noise is much smaller than with analog television. This ensures a much better image quality. In addition to image quality, digital television also offers better sound quality and not only stereo sound can be transmitted, but Dolby Digital surround sound can also be sent with certain programs or films.

HDTV (Digital television)

In addition to the ‘normal’ digital image, we can now also receive High Definition digital television. This form of digital television has an even sharper image and offers more interactive possibilities. More information: High Definition
To enjoy HDTV you have to take out a separate subscription with your cable company, which sometimes involves additional costs.

Types of digital TV

There are several ways to receive digital TV in the living room;

  • Via cable (DVB-C): This is the most commonly used form. Digital signals come into the house via cable and are converted by a decoder (set-top box) into images on your TV. (eg Ziggo & UPC)
  • Via the ether (DVB-T): Digital signals are taken out of the air by an antenna and converted by a decoder to image on your TV (KPN Digitenne)
  • Via satellite (DVB-S): Digital signals are received by a satellite dish and converted by a decoder to image on your TV (Canal Digital)
  • Via the internet (IP-TV): If you have a fast internet connection, you can also receive TV channels digitally via the internet and then forward them to your TV. (Tele2, KPN)

In addition to better picture and sound quality, digital television offers other advantages; This way you can receive many more channels than in the standard analogue package, such as music, travel, eroticism, etc. Simply put, there is simply more space on the digital highway to place channels, so this is fully utilized. For some extra channels you have to pay extra money. When you bring digital television into your home, you also have an EPG (Electronic Programming Guide), an electronic TV guide. With your remote control you can select a special menu on which you see a guide of all available channels. So you no longer need a paper guide for this! In addition to the EPG, digital television offers you the option to pause the programs you are watching at any time and continue watching them later. As a final advantage, some cable companies also use VOD (Video on Demand). Via this function on your decoder / set-top-box you can watch paid or free programs and films at any time.
