what resolution would a movie on Australian HDTV be - Blu-ray Forum

crizz · 06-11-2008, 06:18 AM

Watching HDTV in Australia and was wondering what source and resolution the movies would be that they show on free tv like channel 9 or 10 for example. It appears to me to be higher quality than a dvd but not as high as a blu-ray. Anyone out there know what source they would be playing this from and what resolution it would be?

thanks for any info

I do not know about Australia. In the US, it runs either 720p or 1080i depending on the channel. The signal is still compressed so that is one reason why Blu looks better. Blu has far less compression and can run at 1080p. I would guess that is is not much different in Australia.

The most common adopted tape format for broadcast is DigiBeta. So logically the more common adopted HD tape format is BetaHD aka HDCAM SR. These are maximum bandwidth recording format which then gets online re-compression prior to broadcast. The HD broadcast signal is not enough for a full bandwidth broadcast given the broadcast spectrum.

Sometimes a movie may come optimally-compressed, that is the station need not re-compress them because they were already compressed to the broadcast bandwidth. Those may or may not look better.

I believe Australia's using DVB AVC at 1080p. I could be wrong.

Nobody uses 1080P for terrestrial broadcast. 1080i is the maximum.

Australia is using DVB MPEG2 according to Wikipedia. I believe that Foxtel might be introducing (or already using) DVB AVC.

On the rare occasion that I actually watch TV via a TV signal on my HDTV, it says "1080i" on each channel.

ok so even though a moive may not be released yet on blu-ray a tv studio has access to copies of the movie on BetaHD which are higher picture quality than a dvd??

The studios' access can be film, 2K or 4k digital master, which is higher than DVD.
