Oh no, I hope they dont turn on the fake surround option. I cant stand even dolby prologic processing on stereo stuff, hate to think what the encoder will do to make noise that shouldnt be there come from speakers that are not meant to be active.


From what i've heard this "fake surround" is much better than the prologic / PLII stuff, the unit that does it is brand new and fabulously expensive. If it does bother you I guess you could switch to the AAC stream for non native 5.1 programs, or switch your receiver to only output two channels. 

As for the mux capacity, each mux has only a certain amount of bandwidth, all TVNZ channels are statistically multiplexed into single data stream which is then broadcast on a specific frequency. The more channels you add to the mux the less data there is per channel. The only way around this is to create a 2nd TVNZ mux on another frequency, which I imagine will eventually happen, but probably not for a while. I don't think there is the demand for 6 & 7 in HD to justify the expense at this point.

Yeah, I have a freeview sat box for C4 and C42 because the trebble on the AAC streams sounds so bad on anything even 1/4 decent. Really wish they would move to AC3 instead of AAC but dreams are free I guess. Would sooner put up with fake surround with stuff coming out the rears than listen to AAC with SBR making it sound faker than most things on tv.

Which is why there are 4 or so versions of TV1 on the freeview sat service.....

Good to hear TVNZ is upgrading their systems throughout the chain.  Surely a HD studio camera or two should be on the cards though?

As previously discussed a HD camera is cheap. The rest of the production chain from camera to board, mixing console etc. is not and wasn't ready yet. That is why the TVNZ person they considered but decided not to, park an OB van outside and use its facilities but that does seem a bit OTT.

"perceived volume" processing on the output chain rather than an optimod?????
No more loud commercials!!!!
