I'm getting it here in Lower Hutt, channel 21 on Freeview HD.

Also, the HD test channel (100) is gone.

It's not uncommon for new channels to start before the advertised launch date - whether it's a test pattern, promo reel, or the actual feed of the channel.

Just like how Sky are currently showing TVNZ7 on channel 97 AND 77 - in preparation for it's move to 77..  only thing is channel 77 seems to be locked at the moment.

It's great to see another dtt channel start. I needed to manually rescan the kordia mux to get it on the old Zinwell though.

When do you think stratos will get widescreen correct? It's all over the place!




don't mess with me.... i'm the hd insider....

More content is always a good thing.

On the widescreen issues, I suppose they still have a few days until the official launch to get it right - assuming it's easily fixed, that is...

I also see that Stratos is in SD. Since it's replaced an HD test channel on the Kordia mux, am I right in assuming this allows room for one more SD channel on that mux??

Anyway, unless TVNZ or Mediaworks subleases room on their mux, are we getting close to capacity???

I'd say we're close even if TVNZ or Mediaworks sublease. There is still a little space on the terrestrial network.

Terrestrial
------------
TVNZ: 3% (~800kbps)
Mediaworks: 10% (~2.6Mbps)
Kordia: 30% (~8Mbps)

Summary:
- there's basically no room on the TVNZ mux - they'll have to cut quality if they add AC3 for both TV One and TV 2 (TV 3 uses ~400kbps for AC3)
- there's possibly room for one more low quality SD channel on the Mediaworks mux. Alternatively (and preferably in my opinion) they could upgrade FOUR to HD if they cut quality a little on TV3 and TV3 Plus 1.
- there's not really enough room for another HD channel on the Kordia mux unless it is an upgrade from SD to HD (I'm looking at you Prime!!!). There should easily be enough room for 2 if not 3 SD channels considering current bitrates. Note that I'm not receiving tvCentral here, but I do receive ChineseTV and TV33 (total of 7 TV channels + 3 radio).

Satellite
----------
12456H: 6% (~1.9Mbps)
12483H: 6% (~1.9Mbps)

Summary:
- there isn't really room for any more channels on either transponder - at least not at qualities I'd be interested in watching

They have fired up a re-transmission of TVNZ7 to cover channel 77. I'm assuming we'll see this copy go away once the move completes.

What number is the Travel Channel moving to?

you know all sd channels are broadcasting at 16:11 not 16:9 aspect as the display size should be 1024x576 but its 1047x576 witch is 100% WRONG

And tv3 uses 384kbps for ac3 audio

I'm not sure what the SD aspect ratio has to do with the bandwidth availability comments I made, but I certainly am not receiving that AR. Rather, I believe I see 1024x556 here...

Regarding the 384kbps: I read all my stats from Transedit. Obviously they are not exact, but they're pretty close. Further, if you take the overhead for PMT data into account then I'm sure you'll find the bandwidth for the TV 3 AC3 is something like 400kbps. Wink

On DVB-S the channels are transmitting 720x576 with an AR of 1.78:1 resulting in an output of 1024x576

On DVB-T the SD channels are transmitting 720x576 with an AR of 1.82:1 resulting in output of 1048x576 which is wrong.

The HD broadcasts are full 1920x1080 and also have their AR tagges as 1.78:1

a bit OT, I just scanned Mt Te Aroha (freeview HD) and I'm now receiving "TV 33" also.

edit: I found it using Windows Media Centre but my parents's Homecast DVR finds nothing on channel 33

And since when has 1047x576 been anywhere near 16:11. 16:11 is actually more square than 16:9 yet 1047x576 is more elongated. 16/11 x 576 gives 838x576.

16:11 is an AR of 1.4545 which is obviously totaly incorrect in anyone's math.
