Article in stuff talking about the challenge of selling Freeview.

http://stuff.co.nz/4043168a28.html

In the article is the following comment

State-funded broadcasters TVNZ and Maori TV must make any new channels they launch available on both satellite and DTT, but only DTT will have the capacity to support high-definition TV broadcasts.

That's a bit annoying since it means to get HD many of us would have to have both a STB for DVB-S and one for DVB-T (MPEG4 presumably).

Is the satellite capacity such that they either cannot potentially broadcast HD over it or they don't want to and/or have to bring out a new STB for DVB-S?

Technically there is no reason at all that you cannot do HD over DVB-S, however, when you are handed spectrum on a plate compared to paying an overseas entity for transponder space there are compromises to be made.

When all said and done doing SD in the DVB-S service will at least bring FTA good quality SD feeds to the population that normally struggles to get anything. The DVB-T service will most definitely be go to introduce HD to the main markets.

In a couple of years or so there is no reason why HD cannot be distributed over the DVB-S service once its realised that there are only so many stocking filler channels folk will take before you amp it up.

TV3 will be going HD over DVB-T in 2008. This is confirmed in the April issue of Onfilm. Whether the new owners see this through or not has yet to be seen.

NZ DVB-T boxes will be mpeg4 and possibly have digital video outs (HDMI etc). This sets them up perfectly for HD services, all they need is the extra bandwidth per chanel.

DVB-S boxes are currently mpeg2 and analog vid out, so when/if they introduce HD over sat you'll need a new box.

If they do HD over DVB-S I would get a new box. I guess it depends on how my OTA reception will be - currently it's okay to average but there is a bit of multipath interference on UHF which might not be tolerable on DVB-T broadcasts
