ABC HD Channel 20


Recommended Posts



Seems to be not working in northern tas either, just jumps back to the main SD channel on my PC DVB-T card.

That's because its a re-direct. The HD would be late by 1 hour during the evening otherwise. This will revert to normal in a week and a half.

The ABC has only one set of HD encoders for the whole of Australia. On top of that there are no native HD programs at the moment. The up conversion is no better than the SD service. In fact due to Mpeg proccessing some SD material will look worse being up-converted.

Having said that the ABC has a lot of good SD programs (technically) and they up-convert very well. But compare SD and the HD (up-converted) on 2 STBs and monitors and you will see bugger all diference.

Thanks for the info guy's. I spoke to master control in Hobart yesterday arvo but they had no idea what was going on. I must say though to my untrained eyes the pq on channel 20 does seem to be a little better if only marginally. I understand that it,s only an upconvert from the already very good quality sd picture but it seems to look better. Any thoughts as to how this could be ?

It is because there is more bandwidth given to an HD stream by nature of the fact that true HD is more bandwidth intensive than SD. Therefore an HD upconvert if properly done is less likely to display compression artefacts than a comparitive SD stream.

Thanks Nickcom I'm please to hear there's a technical explanation for what I think I'm seeing. We can only hope that WIN & Southern X will look that good some day.
