Hi

Since NZ is hopeless market to find parts for so many things Im looking further afield.

Are the broadcasting signals the same here as they are in Australia so if i buy a tuner unit there it will work here?

No, to my knowledge, they are not the same.

i believe that the same 'tuner' will work in both markets, but whether it will decode the signal is another question.

Aussie does MPEG2 last i looked, whereas we do MPEG4. The sound is carried in different formats too.

A PC tuner card should work in both places, as you only need to install the right software on the PC. A set top box may, or may not, depending on the manufacturer. A TV with an integrated tuner most likely wont work in both markets.

Hi, the standards are similar but not the same, we both use the DVB-T standard, however Oz uses 7MHz channel allocations in both VHF and UHF, where as we use 8MHz allocations in UHF only. We both however use the same or near identical COFDM parameters.

The other major and most significant difference is that Oz uses Mpeg2 coders for both SD and HD streams, we use Mpeg4, naturally the latter can decode the former but not the other way around.

You will find most integrated TVs from the major brands will ask which country you are in with Oz as the common other country, these sets will work in both country setups without issues. Other brands have firmware thats country dependant (including FreeView Mheg requirements) but the builtin decoders will be Mpeg2/4 capable with adaptable 7/8MHz tuners.

That maybe because your TV has a country setting in the tuner.    I'm sure a STB made for Ozz would not take into consideration that someone here  may want to buy one and use it here..

All true, even though they are broadcasting in MPEG2, Aus FV devices have to be H.264/MPEG4 capable so that should also apply to stand alone Aus FV boxes.

thanks Cyril

So as long as I get a DVB-T Mpge4 decoder that can work on 8mhz I should be right?

Also are you saying our digital channels are only on UHF?

Yes, our FreeView UHF service is only UHF.

Oz has had a DVB services for 8yrs or more as mentioned before Mpeg2 only.

Originally it was a single mux per broadcaster and they typically only had the one program but with an HD stream and SD one, also originally you could purchase SD only decoders hence the dual streams. Eventually broadcasters were allowed to add extra channels, the EPG was very basic, ie just EIT and no linkage between broadcasters, so if you didnt go to a particular channel for a while you lost EPG from them.

Once FreeView launched here the TV exec's headed over and realised the advantage of our common platform owned run by a single company (FreeView) of which all the main broadcasters were shareholders. So in 2008 they launched their FreeView and came up with a plan to eventually mimic what we have, this includes a move toward mpeg4 (so new TVs/decoders are mpeg4 capable) and also support a central mheg5 EPG.

Hence the differences are now minimal, at least in product spec. As for tuners, most tuner module manufactures have supported both 7 or 8MHz (and 6MHz in some countries) for 8yrs or more, as to if the decoders firmware supports selecting as needed is another matter, but one assumes they do.

Several people have reportadly imported car tuners and they work except for needing rescanning as you go between infill and main signals and the lack of an EPG on them.

Probably not as it is only talking about SD resolutions, so you would be ok on four, c4, prime etc for now but if they pull finger and go HD, you would be out of luck.

There are some boxes that are MPEG4 for SD and MPEG2 for HD as well, so you really have to watch out that they will do HD and MPEG4, but if they do then you should be good to go.
