Pesky Dolby audio support, DVB-T
Dolby Stereo in DVB-T is coded in AAC -- well, at least in ATSC it is.
The net increase in bandwidth per channel-audio-stream would probably be no more than 10%, for Dolby support. For a lot of programming, it just is not needed. YLE, and others -- are probably avoiding Dolby as most programming does not justify it. With time, and more bandwidth -- it will come. There are studio switching issues too... When it does come -- Finland will probably be better off than Australia. Australian broadcasters did a lot of homework before the DVB-T switch ... thus the temporary advantage. I would hardly call it bit starved. With a 23Mbps transport stream you won't get more than a 13-15Mbps HD video channel plus a 6-7Mbps SD video channel plus a 1.5Mbps video programme guide plus multiple dolby digital and MPEG audio streams. whining I envy you Australians. In Finland we have in each DVB-T multiplex (or transport stream) five or six SD channels, 2-3 Mbps each :( There's no dolby on any channel, probably because the only carrier company in Finland charges so much for bandwidth, and I haven't seen even plans on starting HDTV. |
US ATSC conversion: with 700 some odd days until NTSC is turnedoff, you would think that US TV stations would run a dayly counter...

But don't worry it will only be a matter of time before the standard is just a foot note in history just like the long list of USA centric communications standards. At least the USA was out there seting standards, unlike Australia. We do set standards but ONLY after we have collaborated with other countries as part of international standards organisations. We're not arrogant enough to think that we're more important than everyone else and as soon as we set a standard everyone else will follow. Even after Vietnam and Iraq the USA still thinks it can rule the world on it's own.... Some hard lessons still need to be learned. I agree, we need to stay home and let the rest of the world GO TO HELL!!!! Yes, I think the Iraqi's would certainly prefer hell right now to the civil war bloodshed they're currently experiencing. What the hell was up with your country allowing Nazi's to keep US and allied prisoners of war on your Aussie soil in WWII? WTF are you on about? We kept German & Japanese POW's on our soil during WWII. Why would we keep our own and allied forces as POW's inside our country????? |

Besides USA bashing, exactly WTF is your overall point supposed to be? In case it got lost, my point was that perhaps the conversion/adoption of digital TV would have been accelerated globally if more countries participated in an international committee to determine the best terrestrial digital TV standard rather than developing their own format for domestic use. Oh well, no use in crying over spilt milk, the sooner crappy analogue NTSC transmissions in the USA are switched off the better. |

Haven't the cut off dates now been extended indefinitely? |

I think part of the reason more European TV viewers aren't up in arms about how the continent overall is about a decade behind the US in over-the-air HDTV (and at least several years behind in cable/satellite HDTV) is that European reports on HDTV adoption almost never talk about the US experience. It is a fundamental part of the European psyche, brought about by the trauma of two world wars, that Europe is superior to the US. Reality is too much for them to handle. Europeans can not compare themselves to the US, other than to reinforce their feeling of superiority. "Those Amazing Kangaroos!" Reminds me of those American fools who think that all British TV programming is as good as (and is of the same genres as) what appears on Masterpiece Theater. Tell me about it. I'm not sure which is worst: limey TV or kangaroo TV, but they're both equally bad. Leave aside flickery PAL. The programming has poor production values, and low-brow (or no-brow) material that makes Hollywood look like a pinnacle of culture by comparison. Not only that, they pay a tax to the national broadcaster for the privilege! Think about PBS. Now remember that what PBS has is the cream of the crop. -- Mark -- http://staff.washington.edu/mrc Science does not emerge from voting, party politics, or public debate. Si vis pacem, para bellum. |

Like ATSC, DVB has "foreign" members - but they don't run things. The DVB staff members are employees of the EBU and changes to standards need only be approved by EU standards bodies to enter the DVB standard. |

The DVB didn't even start organizing until 1991. Now... who was it that didn't join the HD party already in progress to for "form a concerted pan-European platform to develop digital terrestrial TV" separate from North America? YES... it was the Europeans who decided NOT to go along and instead have an all European solution... just like they did in the NTSC(1950 color) / PAL(1963) / SECAM(1956) days. |

The US refuses to abandon preexisting standards work to accept European-centric standards, and they are bent on world domination. This is just not rational thinking. |

They did the same thing with satellite navigation. First the EU demanded that the US give up GPS to international (meaning European) control. When the US demurred, they went to the Russians and demanded that the Russians turn over GLONASS to them so they could make a GPS-killer out of it. When the Russians also said no, the EU embarked upon their Galileo program to be both a GPS-killer and GLONASS-killer. The satellite navigation community, being a sort that says "the more the merrier" on satellites (more data, better fix), has had no particular problem. People use dual GPS/GLONASS systems now. But now the Europeans are refusing to release the necessary Galileo technical specifications so that manufacturers can start producing tri-system receivers, and are hinting that these specifications may require per-receiver license fees. Both the US and the Russians have open, free specifications for the civilian signal. Let's not forget the longstanding foofaraw of Internet governance. The main reason behind the European attacks on ICANN is not about any malfeasance of ICANN, but rather that they don't own ICANN. They'd be quite happy if ICANN were in an ITU office in Geneva. Among other things, the Europeans are upset that they can not ban certain entities and certain content from the Internet; and they feel that by controlling ICANN they could acquire the power to do so. It should be noted that the US *has* used European standards when they made sense. GSM is an upgrade to TDMA (although some of us would say "not enough of an upgrade") and it made sense to replace TDMA with GSM. Then again, Japan leapfrogged GSM to go to UMTS... -- Mark -- http://panda.com/mrc Democracy is two wolves and a sheep deciding what to eat for lunch.
