Abc1 Soon To Be Hd ?

Recommended Posts

The ABC are probably so desperate to save money that by moving to MPEG audio they don't have to pay royalties to Dolby or their license fee. Given that it's a MPEG-4 HD channel the audio should have been AAC rather than MPEG-1 because backwards compatibility isn't needed.

Oh, and Alanh, for bitrates of 128kbps and higher (whether stereo or surround sound 5.1+ channels) LC-AAC should be used. HE-AAC is preferred only for <128kbps streams.

There is barely any HD content anyway, I remember when HD was a big thing all the stations began pumping out 1080 content everywhere and then it died down, quite a scam if you ask me when we have all these modern high definition TV's and cant watch anything nice on them unless we buy DVD Movies or pay for Foxtel.

Whilst there is still a way to go, over the last couple of weeks, definitely more native HD content on the ABC. Some good viewing last night at, what to the naked eye, appeared a pretty reasonable bit rate (for FTA).

The ABC 7pm News in Sydney on Ch 20 tonight looks terrible.  Have the ABC changed upconverters?  Looks really bad, like no intelligent interpolation is being used to upconvert 576/50i to 1080/50i.  Really bad scaling artefacts.

The ABC news on ABC HD looks terrible everywhere - had a look at all the state VAST channels last night and the quality was very poor.  In my post above, I was referring to general entertainment programming - some of which is native HD.

As I type, The Drum as received FTA in Brisbane on 2 (SD) and 20 (nominal HD)  is very blurry, below the usual standard for standard definition TV.

Why the ABC have allowed this to occur, I do not know.

Foxtel don't go all HD for many reasons (probably mostly technical) but SD legacy boxes isn't one of them. Foxtel realised a few years ago that getting an IQ box into a household dramatically reduced churn. They've been practically giving away IQ (HD) boxes to anyone and everyone for years.

That still leaves a lot of IQ1 boxes, of course.  No MPEG-4 on those babies.  The IQ1 reduced churn just as much as the IQ2.

That being said, we are now 11 years down the track.  I do expect the percentage to be far closer to 0% than to 100%, or even 50%.

I've met a couple of people that have IQ2 boxes without the HD package, so Foxtel can't be considering them to be *too* valuable to waste.

ABC radio continue to bang on about ABC TV in HD on new years eve commencing with the fireworks.  We live in hope.........

Things have definitely changed from the days of 1999-2000 when Four Corners released a special report condemning HDTV.

So — let's talk upconversion.

The quality of ABC SD material has really taken a hit.  They're using a different upconverter than was used on ABC News 24 and previously on ABC HD in the MPEG-2 720p days.

This new upconverter handles the logo automatically but takes 100% of the news content and makes it really blocky.  Same goes for anything not sourced in HD.

The really interesting thing is comparing QandA from when it's in Sydney (studio 21, using the news department playout in pure SD) versus QanA on the road, when it's in HD.

So while we have some really good news-ish content in crystal-clear HD now — e.g. Media Watch, Four Corners — we're left with a downgrade for everything else.

And it's not like the other networks where the SD material goes out 'raw' on the SD channel — no, ABC upscales SD to 1080i, then back down again for 576i.

So the SD channel looks rubbish too now.

That's not correct. The very first IQ box was MPEG-2 and SD only (very very few of these are still working in the field). The more compact IQ1 released around the time of the IQ2 was very much MPEG-4 capable. It could even decode 720p HD as well. The IQ1 stores and plays back streamed content on the SD MPEG-4 version of the timeshift channel which saves space on the hard drive. The SD MPEG-2 timeshift channel has only been needed for the very old first gen IQ STB's.

Heh, cool.  I guess it doesn't make much sense to call it an IQ1 then really?  Just must be their internal designation.  So what CAN'T it do — 1080i?  HDMI?  Maybe it should be called the IQ1.5 or something.

Well well well, something seems to have changed in the last 7 days.  Or at least it impacted Sydney between yesterday (Sunday) and the Sunday before that.

I have a recording of the last two Insiders episodes — plus the news bulletins before that — and the one from the last 7 days is significantly improved.

I think we're more or less 6 months into ABC HD Take 2.  6 months seems to be how long it takes the networks to get their act together … we saw the same thing for HD content to appear on GEM and 7mate, and Ten HD went into a 6-month overhaul around 2003 before the quota came into effect.

We're into Take 3 of Ten HD now … but there's still no HD on it from TV series outside Australia.  I would love some new CBS content in native 1080i / 1080pSF one day.

The free to air networks probably buy the SD versions of shows from overseas to save money

Slattery,

This is unlikely. The main suppliers of overseas ABC programs is the UK which has been purely HD production for a long time as has the major networks in the USA. The UK does simulcast SD versions of their HD programs, but the downscaling occurs just prior to transmission.All UK HD transmission is MPEG-4 where as in the USA it is MPEG-2.

It would cost them extra to make special SD version for the ABC.

The cost of satellite time is related to the data rate. The data rate for SD MPEG-2 is about the same as HD MPEG-4. However the ABC rarely does this because it cannot afford the program rights for the original program let alone the satellite time so no live via satellite.

The only live satellite programming is news which is distributed to many broadcasters from the same satellite at the same time which reduces the cost to an individual broadcater.
