Digital TV Explained

What Is Digital Television?

Digital TV is the broadcast and reception of digital television signals. Television has traditionally been broadcast as analogue signals, but New Zealand will be phasing these out over the next few years. The New Zealand government projects that all television broadcasts will be digital signals by the end of 2013.

What Are The Benefits Of SD Digital TV?


  • Superior picture quality.
  • Clearer reception, eliminating ghosting and graininess often present in areas receiving poor reception.
  • 16:9 widescreen images.
  • CD-quality digital stereo sound.
  • Digital program guide.


What Are The Additional Benefits Of HD Broadcasts?


  • Even sharper, clearer images — superior to DVD quality.
  • Cinema experience with widescreen and Dolby 5.1 channel Surround Sound.


How Do I Receive Digital TV?

Digital TV: Most new TVs – plasma, LCD or LED LCD – feature integrated HD digital tuners.
Set top box: Cost effective solution for people with older analogue televisions.
Digital recorder with integrated Freeview HD tuners: Personal Video Recorders (PVRs) are the digital equivalent of VHS recorders. They allow you to watch and record digital TV.

  • Twin tuners allow you to watch one program while recording another.
  • Store hundreds of hours of recorded programs with a hard disc drive.
  • Time Shifting buffers up to half an hour, meaning that you can pause and rewind TV, and catch the start of the show, even when you're late.


Do I Need A New TV Antenna?

Most of New Zealand homes are covered by UHF Freeview HD. If you receive most analogue channels clearly now, you should not need a new antenna. If your coverage is poor, you will need either a new UHF aerial or a satellite dish (which requires a Freeview satellite decoder too). If you are not sure that you are covered by the UHF signal, check www.freeviewnz.tv/get_freeview or contact your local aerial specialist.
