I've checked around, and as far as anyone knows, TVNZ are not applying any sharpening or processing to the signal ex Host at all. Looking at the pictures off-air they do seem more compressed than TV3's, mostly due to squeezing 2 HD channels into the mux. I can tell you, the uncompressed HD-SDI pictures from the truck look amazing, but that really doesn't help anyone :)

The sharpening on TVNZ is on all material, not just the rugby. It maybe how they are encoding it for Freeview.

tehconz: squeezing 2 HD channels into the mux.

This may have a lot to do with it, and assuming they are variable, what is going on on the other channel/s might have quite an impact. I have seen quite a difference each week on TV1 but less on TV3 that I recall. TV1 looked very sharp (in a nice way) a few weeks back where TV3 looked very soft. TV3 had more saturated colours last week, where TV1 looked quite washed out/bland by comparison.

Yes, statistical multiplexing is used to dynamically allocate bandwidth to channels with the highest spacial / temporal complexity.

Personally I thought the TV One picture for the RWC has been generally good. Closer shots in particular showed great clarity. The grass did look a little odd at times on medium-wide shots with a fair amount of motion - just over-compressed a little I think. I haven't watched a lot of TV 3 during the world cup but generally I find their colour to be over-saturated. Shows like NCIS (skin tone) and CSI (generally - shirt colours etc. *very* vivid) are a good example. Maybe it is just the content, my eyes or my setup but I definitely prefer TVNZ on that front.

If you have a HD satelite reciver you can get true HD TV from OZ for free.
there are 4 stations broadcasting to NZ you just do a blind scan then delete the ones that you do not want.
If TVNZ is not carefull thay will lose the market. i watched the world cup with out delay in HD
any sky dish with a ldn that looks like a double icereem cone will work.

Only SBS HD abd Gem are HD and most LNBs will work, nothing to do with icecream

And gem is only 1440x1080 mpeg 2 at 10mb/s which is very poor for HD. Also sbs HD isn't Dolby and I've still not heard 5.1 on gem. Also go! is 704x576 which isn't even SD.
Don't forget that you also need a dvb-s2 receiver for some of these and that they're all temporary and could go at any time.

Anyone else think that the rugby on the gem channel looked better than tv1 or tv3 HD? It didn't to me. And no surround... Australia missed out on points there too...

Sound was very 5.1 though.

I reckon TV3 won out tonight's Wales vs Australia.

Surround sound was very engaging, and the colours good. Not as sharp as TV1 but TV1 had bland sound and motion/compression artefacts. Overall TV3 much more engaging I thought.

the sound tonight on TV3 for the rugby was not in 5.1 sound and it was really loud, TV1 and sky were both in 5.1 and the sound was a lot better, not as loud, so not sure what happened to TV 3

Common sense is not as common as you think.

I don't have 5.1 sound but the picture on TV One was the winner in my book again tonight. I looked carefully at the grass in particular and TV 3 seemed blurrier or softer. Whether that is the result of TV One sharpening I don't know, but if it was, it didn't look over-sharpened to me - I liked it. A few artifacts when the camera panned, but not distracting...
