Final Days For Australia's Analog TV
jones_supa writes "The switch to digital TV broadcasts in Australia has entered its final few days, with Sydney's analog signals being fully switched off today, 3 December. That just leaves Melbourne plus remote central and eastern Australia — and those areas will be switched over on 10 December, completing the country's transition to digital TV. The government runs an information site to assist the remaining crusty luddites with the switch-over."
Analog degrades better if you're on the fringe.
Digital is pretty much "all or nothing", with freezes, posterizing, etc.. if you've got a bad signal.
If you've got a bad analog signal, you'll get snow and static, but you'll still be able to see what's happening.

How do they know it with digital TV?
DVB-T - simplex transmission, just like analog.
DVB-C - also a simplex transmission.
They can only track you if you use IPTV or connect the box to the internet so it can phone home.
Get or build a better antenna. And put it up higher, and point it in the right direction. Use a signal amplifier. These things work.
Indeed. I don't know what they'll be using in Australia, but here in the US, 8-vsb transmits 1 error correction bit for every 2 data bits. I live in a small town in a valley that's 30 miles from the nearest television transmitter.
Australia uses DVB-T which has different propagation characteristics than 8VSB. DVB-T makes it easier to do SFN (single frequency network) because it resists multi-path interference (ghosting in the analogue world) better whilst 8VSB has a better power dispersal profile, which means larger coverage areas from one antenna.
