Optus will be first to broadcast,
they have tested in recent times 12607
I would assume in readiness for EPL season 2
Wasn't sure where to put this.
Anyway, what are peoples thoughts on 4K UHD in Australia?
We have 3 main broadcasting platforms;
DVB-T
DVB-S2
IPTV
I notice in the UK and a few other Countries that 4K UHD is broadcast via DVB-S2
We have plenty of 4K TV's being sold
Do you think you will get 4K here in Australia?
And how will it be delivered?

Sky and BT in the UK have 4K UHD Broadcasts via Sat (been around for 2 years already)
Virgin is 4K Ready
Direct TV in the US has a 4K UHD Broadcast
ESPN is 8K Ready
ATSC 1.0 & 2.0 are not compatible with 4K/UHD.
ATSC 3.0 is compatible. With ATSC 3.0, there is no backward compatibility
(This means, of course, the same problem we had with with the Analog to Digital transition. Everyone has to have a new TV receiver or a set top box of some kind)
Yep, if you buy a 4K TV today, you will need a new STB to watch FTA Terrestrial 4K if it ever becomes available in Oz.
I'd rather see all Australian Channels be 1080i, before a few were 4K / UHD.
But it seems, we cant even get a majority HD, let alone UHD
We are so far behind other countries its not funny
But, we are a big place.
Still, the technology has been here for years now.

I have no idea what costs to the broadcaster would be to use this system and would advertisers be willing to pay more if there is any based on reports every one is crying 'poor' in the current economy.
Also, based on the 3D debacle, is Joe Public ready to spend on replacing sets that are still fairly new?
I stand unequivicably behind everything I say , I just dont ever remember saying it !!
3D was a joke the second it was proposed.
Something for Sci Fi Movies, not day to day TV consumption.
I see resolution upgrade a natural progression
Just as CPU's get faster, Internet Speeds get faster and so on.
Id say a 720p/1080i base across all channels isn't hard to implement and probably all people with up to 60" Displays need
4K UHD is a different story, it most likely would be delivered via the Internet or Sat i guess.

Silly question. Why do we need higher resolution in our TVs anyway? Surely the picture is more than adequate to convey the information as it is. It's not as though we need to see the zits on Elle McFeast's backside while we're watching the footy.
I'm out of my mind, but feel free to leave a message...
I guess with that argument, one could say why move away from CRT Screen TVs
SD on Australian Pay TV is horrible, bordering on unwatchable. Especially in sports with wide angle shots.
DVB-T is ok for the most part.
But when you go to countries like Vietnam where i counted something like 112 HD channels in my motel room
Makes you wonder why we cant have our main channels all HD.
Why do we have Full HD TV's when only a handful of channels are HD
Hence, the same argument with 4K

I agree with SD being horrible for sports, but that, in reality is about all that we need HD for. Why UHD has got me baffled. Maybe, if you were a surgeon operating by remote control...

The information is out there; you just have to let it in."
Are you saying, Tiny, that we would get more of the story with HD than with SD? I agree that there is more clarity with HD, but, realistically, is it going to improve the story any? If movie makers have to rely on pretty pictures to tell the story, they need some better script writers.

It's like a mental thing for me. Once you get used to HD broadcasts, SD is unwatchable. You notice all the glitches, and the picture looks really blurry compared to HD. Genuinely it's like developing a trained-eye for resolution spotting.
Having owned at one point a 4K monitor for my PC, looking right now at my 1920x1080 screen, it looks like an old plasma screen. My eye can pick up all the little "blocks" or "matrix" and the on-screen text is so pixelly. The 4K experience is like looking at text that was printed on a laser printer in comparison, with much greater contrast and a much greater colour spectrum.
And that's the thing. I can guarantee, watch 4K for six months and HD will be terrible. Just in another league all together.

Makes me wonder if 4K UHD will be just easier to deliver over the internet.
3.0 Megabits per second - Recommended for SD quality
5.0 Megabits per second - Recommended for HD quality
25 Megabits per second - Recommended for Ultra HD quality
What a shame so many UHD Smartphones are Ready to Receive it, but Homes aren't

I think your domestic TVRO sat system will eventually be developed for full use with Ka-band (around 30 GHz) which might allow for UHD tps to be stacked in nicely like the HD and SD stuff on the Ku and C systems we have now.
That was one of the issues with HD when it came along initially - capacity on the bird. Improvement and progression in compression technology, standards, etc. of course helped, but eventually I think this higher frequency band will be migrated into.
But, I think you're right. Internet will probably become the main platform.
It'll be a sad day when the satellite dish is no longer relevant.

As a point of interest
H.264 4k needs around 25Mps to stream without buffering
H.265 for the same 4K stream only needs around 13Mps
Of course, fps will change this, i think the above was based on 30fps.

I stick to ur New 4K 86 Inch Dolby Vision TV + Oppo 203 for Dolby Vision and the Panasonic DMP UB 900 for HDR 10 Blu ray for now. I was going to buy a Vu Untimo but because 4k is limited on sat I will wait for a little while. Having fun with our new TV and everything we have purchased lately for our main TV room
I can't see it happening anytime soon. Here's my two bobs worth
DVB-T:
What BW would we be talking about for one FTA UHD channel?
Is there enough BW now, or would the broadcasters be forced to drop 1-2 of their not-so-quality channels to facilitate a UHD channel each?
I'd be more than happy having less channels of quality (content and picture quality) over the shitty quantity we are forced to have.
DVB-S2:
This will limit the viewing audience to whoever had a dish aligned to that particular sat providing the FTA UHD channels.
If broadcast on Optus C1/D3, this would require a separate STB to receive the channel/s; in-addition to those that have F0xtel.
Hobbyists would be best placed to receive providing they have a suitable STB.
If not Optus C1/D3, this would require a second dish (or LNB) to receive from another satellite; reducing viewer audience greatly.
IPTV
This would extremely limit the viewing audience to only those with the fastest internet connections.
Most on ADSL2+ or less connections would be un-watchable, as the non-stop buffer would be enough to turn it off.
Mobile devices with the mediocre data limits we have in OZ, would be in excess data usage before you knew it.
Maybe MTV can provide more info on bandwidths required for UHD channels and if there is space for broadcasters to implement one or more channels.
