8. Do I need a set-top box to watch DTT?

If you have a simple television set (analogue) or an integrated digital television that can only decode video in MPEG2 format, then you will need an external set-top box.

When choosing a set-top box, make sure it meets the following characteristics:

  • it is compatible with DVB-T; 
  • it is compatible with the MPEG4/H.264 standard; 
  • it is able to decode HD (high definition), if you want to watch HD television in the future.

In areas covered by alternative means to DTT (e.g., satellite - areas of DTH reception), check with PT Comunicações, by calling 800 200 838 (freephone) or checking the DTT Website, since the equipment needed is different from the equipment indicated above, used for terrestrial DTT reception.

There are 3 types of set-top boxes:

  • Basic set-top box (Zapper Box) - only gives access to the DTT service, without any additional features. These boxes can be of two types:

    - SD Zapper Box - only provides access in standard definition and not in high definition, even if your television set is HD capable;

    - HD Zapper Box - Provides access to standard definition and high definition services. However, to watch high-definition, you also need an HDMI interface to connect to your television set and, of course, an HD television set.
  • Interactive Decoder - provides the basic functions of a set-top box and also provides access to interactive applications.
  • PVR Decoder (Personal Video Recorder) - set-top box that can be used to record programmes; can be of two types:

    - using an integrated hard disc;

    - or through a connection to an interface with external storage.
