You can do it now with a computer, or by connecting a Topfield PVR to your computer. But there doesn't seem to be a single set top unit yet. The problem is not electronic.

MrT.
And which responsibilities are those?
Hmmmm where is it getting the signal from to tune that radio from? As far as I know radio stations are not digitised and re-broadcast on digital are they in which case you will still have poor FM performance won't you? There is no circuitry in a STB that could improve the signal. In my place my FM radio is connected to my TV antenna and it works just fine.

How do you work that one out? In many cases what is sitting before the transmitter, or in the case of digital what ever it is that digitises the signal is pretty much the same stuff. Sure the stations may have new camera's etc to cater more for digital TV (Widescreen and all that good stuff that does make digital a good thing), but there ain't nothing that is going to improve the analogue signal coming off the stick. The broadcast quality that was sent before if received on a TV with no problems would match the perfromance of the TV, so where would you see an improvement.
Telecommunications, electricity, gas, water, and many others depending on state/territory.

Try looking up the word "forum" in a dictionary.
"AJ" = what a d*****ad
** The ABC runs two high quality, digital radio signals along with its other TV signals.See:
** The music signal is **digitised** so does not suffer from the problems that * analogue* FM does when arriving via a compromised antenna or in a poor location.

Goodie, same bucket of crap in High Definition. Yippee.
Digitial TV (as with radio) has everything to do with marketing and interactivity. $$$$... there's no need for it except to sucker more people into buying baubles and trinkets they don't need.
"AJ" = an utter d*****ad
** It is blindingly obvious - you cretin.( snip more drivel)
** Only rarely ( until recent times) did broadcast analogue TV signals match the performance of good TV sets - program quality varied over a wide range and only live to air material originating in the same city as the transmitter was reliably first class. The rest, derived from analogue tape storage mediums and over long analogue links was highly variable. Nowadays, digital storage and digital signals carried over those links has put an end to quality loss there.Modern TV sets all have AV inputs - most have S-Video and Component Video inputs as well - so that full benefit of a DVD player's enhanced picture quality can be had. Most STBs have S-Video and Component Video outputs too ( even the circa $100 ones) - since they are capable of DVD grade picture quality or **better**.
If a DVD player or STB is connected via a TV set's RF input the pic quality is unremarkable - though as good as most broadcast signals. When connected via the composite input there is a large improvement, superior even to good live ( eg daylight sport ) broadcast. When S-Video or Component inputs are used there is another, very noticeable improvement on top of that.
The quality "bottleneck" in a standard TV set is the combined effects of the tuner, IF amplifier and colour decoding circuitry - which are simply bypassed by using S-Video or Component Video inputs.

How have they given that away?
Or those?
Why? It's irrelevant to the question.
That's not what you said though:
"Even if you have a perfect picture on all or some channels, the digital picture is so much clearer, so there is a benefit there alone, just ask anyone with eyesight problems who have trouble seeing a normal analog screen."
"just ask anyone" implies a lot more than some.
Since you've only just started using SOME whereas previously your claim that digital would help ANYONE with eyesight problems I'd suggest that you might do well to consult a dictionary.
When is digital TV not TV?
We were discussing the electromagnetic spectrum which is defined by international agreements and run by the ACA, which is a body of the Federal Government. Some frequencies are reserved for military, police, emergency services, telecoms providers, television, radio, satellite, amateur, and other services. The service providers and users are required to hold licenses to use those frequencies allocated to them, however there are some exceptions.
Telecommunications? well that is now Telstra, and only a part of the overall telecoms structure in Australia.
The delivery of electricity, gas and water are/were State concerns, not Federal.
Not relevant. aus.tv is an top level newsgroup for the discussion of all aspects of AUStralian TV. aus.tv.digital was created for the discussion of aspects specifically relating to digital TV in Australia. aus.tv.digital is a digital group. The implication of the other poster's question was that I was posting to a specifically digital group. I am not.

** Questions for DLJ.
The arrangements 1, 2 & 3 are COMMON when STBs are used with old TVs.
The dudes you are debating are likely basing their comments on the pic quality of 1, 2 or 3.

The average VCR picture resolution quality these days - it wouldnt really matter much for most if it came from the analog signal, it would still come out relatively poor
You snipped the part about "A fully digital" It isn't all digital unless you digitize the incoming RF without a down converter. You can't do it on a computer at the received frequency. Is is defiantly a limitation in the electronics. You need high speed A/D converter(s), digital filters such as FIR to process the data stream and a lot of support parts to output a usable signal. I've worked with a receive that digitizes with a 90 MHz center IF frequency that was up to 40 MHz wide. The receivers sold for $80,000 four years ago. They are used to track satellites and can be configured for receive bandwidth and type of demodulation FM PSK FSK QSPK FQPSK and others. The complete system of multiple receivers at multiple sites can be controlled via ethernet or internet. This is the L-3com/Microdyne RCB2000 and you'll probably never see one of them, unless you have a very high security clearance and work for the right agencies.

Anarchy??? Such as?
Thought that was you considering the shit you've been writting in this thread. The sad thing is you actually make some very good and valid points about the benifits of digital TV, but f*ck it up with total stupidity!
Ok so the ABC has digital stations that's cool and didn't know that. In that case it makes perfect sense so there would be an improvement, BUT the orginal poster who asked about radio wasn't specificaly talking about ABC radio, it was just radio, so you would be missing many stations, so the orginal posters comment as to why the hell would you run your radio through the TV?
Again only for a channel that is sent digital. If its just acting as a receiver for a FM radio channel then it does SFA
