his guide attempts to provide an overview to receiving FTA digital TV
transmissions in New Zealand. The New Zealand freeview FTA (free to
air) service utilises two broadcast methods -

DTH - Direct to Home satellite service via Optus D1
DTT - Digital terrestrial television via UHF

If you want to try out DTT under Linux yourself I suggest you take a
look at the following guide on
DTT Debugging under Linux

DTH Technical Details

The DTH service utilises two half transponders on the Optus D1
satellite. Each half transponder is capable of providing upto 9
services.Setting Transponder 1 Transponder 2

DTT Technical Details

The DTT services is transmitted via UHF, covering 75% of the New
Zealand population. Initially 3 multiplexes will be in use capable of
providing between 18 and 20 services.Multipex A Television New Zealand
Multiplex B MediaWorks
Multiplex C Kordia


The current design allows for upto 2 additional multiplexes to be
added at some point in the future.

Unlike the DTH service they have decided to utilise H.264 AVC (MPEG-4)
for the video encoding, and a combination of HE-AAC and AC-3 for the
audio. There will be a mix of SD and HD services.Transmission Encoding

czyli jednym slowem, tuner z Nowej Zelandii nie spelnia naszych
wymagan, no chyba ze wiecej niz wymagaja w NZ.
