It's back to AAC-HE for me on TV2. This new DD audio stream is horrid.
I swear it's just AAC-HE wrapped up in AC3.
TV One is fine though.

Keep in mind that the DD stream is only 384 kbps, or 64 kbps per channel, so don't expect any sound quality miracles. Go live for true 5.1 is supposed to me Monday, and thats when Sky is supposed to be joining the party as well.

Until then even 5.1 shows will go out in stereo as they have to make sure all programs have the right metadata setting (5.1 or stereo). If something is mislabeled bad things (like total silence) could happen.

Total silence would imporve a lot of TVNZ's programming

Are you sure it's not just the relative levels? Also, I noticed that TVNZ is using -7dB for their dialog normalisation (compared to -4dB for TV3).

bazzer: Do you mean -24 and -27? Some time ago all the NZ broadcasters got together and decided -24 was to be the dialnorm standard, TV3 has been running theres at -27 for reasons unknown.

I'm not sure that it has anything to do with bitrate. Even if it did, why does TV One sound crystal clear in true Dolby style, yet TV2 is still sounding flat and lifeless?

More over, TV3 DD sounds amazing compared to TV2 DD. If it was bitrate related, surely TV3 and TV One would suffer from the same constraints? It has to be something on the broadcast encoding process for TV2.

Let's hope Monday brings some fixes.

Yes, I would have thought TV1 & 2 would have been set up identically.

I'm sure viewer feedback would be very much appreciated after the official launch next week, best to ring the call centre on 09 916 7000, all the feedback is directed to the right people.

If you all read the last post on page 7, you will see the link to Screenscribe where it is stated, and in bold, that "TVNZ says it will announce its Dolby Digital plans next week".

Furthermore, and I quote from the item:

"It?s been reported in some forums that the broadcaster already is transmitting in 5.1 audio, as TV3 has been doing since it went HD three years ago.

But a spokeswoman says this is not the case."

Thats a matter of interpretation, while L, R, C, Ls, Rs and LFE are being transmitted, all but L & R are currently silent. So while it is a 5.1 signal, it does not contain any actual 5.1 content as of yet. This has been discussed at length above.

I noticed the new AC3 stream on TV one yesterday (been overseas and just got back). My problem is that the sound level is so low that I have to turn my receiver volume way up to hear it properly. TV3 seems a lot louder.




When you live your life on Twitter and Facebook, and are only friends with like minded people on Twitter and Facebook, you are not living in the real world. You are living in a narcissistic echo chamber.

And when I switch back to another channel the volume is way too loud and I have to rush to the remote and turn it down. I hope that isn't what it's going to be like in production.

I guess I probably do mean that. My receiver reports them as -7 and -4, but that might be from a different comparison point (since -24 + -7 = -31 = -27 + -4)?

Noticed this morning when watching TV1 (the morning programme that starts at 6.30 am) that the blue light on my receiver that indicates "Dolby!" was glowing and the indicators for surround speakers and LFE etc were lit up. I think this is the first time I have seen this from a TVNZ channel. However sound was coming only from the front L and R speakers.

I think this simply reflects some of the comments above but does anyone know which progs from TVNZ will actually be in 5.1? Is there any way to tell an actual 5.1 prog without putting your ear against one of the surround speakers?

If you can't tell unless you do that then does it matter?

As above, all Dolby soundtracks for TV come in a 5.1 wrapper. 
When TVNZ finally officially get this up and running then they should be flagging those programmes in 5.1 sound with a Dolby Digital logo in the official MHEG5 EPG like TV3 do.

Next week's Grey's Anatomy has the Dolby logo in the EPG. (Tuesday TV2)
