DVB-T2 receivers are meant to be backward compatible with DVB-T transmissions. Not that I've seen an Igloo box in the wild but they should (the igloo boxes) be able to decode the free to air services for a relatively seamlessly viewing experience.

There are more issues around the EPG format for New Zealand and decoding MPEG-4 (the later should not be much of an issue really as MPEG-2 is a step backwards to say the least).

Buying a non Freeview approved STB was always a dumb idea because it meant no EPG on 99% of devices.

With Freeview launching an EIT EPG now on DVB-T it means there are devices out there that will support an EPG if they don't support the NZ MHEG5 profile, but only of their EIT EPG supports Huffman encoding (many don't).

In a nutshell buying a non Freeview approved device will give you TV - but whether it will give you an EPG will depend on the device.

Hi there. Every DVB-S I have brought from overseas has had no problems with NZ EPG satellite standards.

However, DVB-T EPG may be another kettle of fish. I dont care either way but thanks for your replies as it sounds like the DVB-T2 will always backward compatible to run DVB-T. Just that the specs didnt show that.

Thanks again.

Freeview DVB-S has always transmitted a non compressed EIT EPG. This however is not the Freeview standard MHEG5 EPG.

Sounds like you are familiar with NZ Freeview. Whats your opinion of what weve ended up with standards-wise? Could it be much improved or is it going to be improved do you know?

Years ago when TV was first introduced here the analogue PAL system we (and AU) adopted was first class.

USA had terrible TV NTSC (Never The Same Colour)

Tks,

Al.

I bought a cheap LCD projector off aliexpress that has DVBT2 in it.

It works for showing channels. Guide brings up its internal one with what is on, not looked to see how far forward it goes, but its got now and next at least.

It autoscans fine, had NZ in the list, but it gets all the igloo crap in the 800's and when you change to it says NO CI INSTALLED as it obviously doesnt have one.

There seems to be no way to get the freeview guide to load on it, no big loss since that thing is so laggy anyway.

IMHO what we have is pretty good. You could argue that maybe we should have waited another 6 months and only launched DVB-T2 for terrestrial but we have plenty of spectrum in NZ so it's not a big issue.
