New UHD 4K TV format, H.265 streaming available 2014/2015


Next-Gen Video Format H.265 Is Approved, Paving The Way For High-Quality Video On Low-Bandwidth Networks
The ITU has approved a new video format that could bring 4K video to future broadband networks, while also making streaming HD video available even on bandwidth-constrained mobile networks.
The H.265 standard, also informally known as High Efficiency Video Coding (HEVC), is designed to provide high-quality streaming video, even on low-bandwidth networks.
In places where there is decent broadband connectivity, H.265 could enable even higher-quality video.
With 4K TVs finally becoming available, there’s an opportunity for even greater video resolution.
The only problem is that networks aren’t built to support the load that streaming that video would require. Using the current H.264 standard.
With H.265, 4K streaming could be possible with as little as 20-30 Mbps of bandwidth.

"as little as 20-30 Mbps of bandwidth"
Compared to my ADSL2+, that's massive. Nice to stream such things, but useless for the many of us who still do not have fibre connections and likely won't in the next ten years.

In the home one also needs to take into account the cost of a television "wall" to make the difference noticeable. Roll eyes

4K UHD is amazing, saw it recently at a Trade Fair.
Japan tests 4K television streams over the internet
"Compressing technologies allow broadcasters to transmit material using much less data than would otherwise be required while minimising the loss of picture quality.
At present the H.264/MPEG-4 codec is commonly used to broadcast digital TV - including the UK's Freeview HD and Sky HD satellite services - as well as the vast majority of video clips on the web.
In January the International Telecommunication Union (ITU), a UN agency, approved a new format to succeed it called the H.265 High Efficiency Video Coding (HEVC) standard.
It allows 4K and 1080p videos to be streamed using roughly half the bit rate, meaning half as much data needs to be transmitted, thanks to the use of more advanced algorithms"

All very well having 4K but I think broadcasters need to spend more of their money on better content and less repeats.

Can anyone actually tell the difference between 1080p and 4k?

Not at typical domestic screen sizes and viewing distances.

The BBC has started a closed trial of HEVC (H265) trial using DVB-T2 on DTT platform.
The test which appeared in mid June on the frequency of COM8, uses 35.92 MBps for the video, with stereo audio.
The broadcasts are currently being evaluated at three BBC sites, and are being broadcast from only 3 transmitters – Black Hill, Winter Hill and Crystal Palace.
First broadcast was of a BBC building with sweep tone, then a few “geometric abstractionist” style test cards with a tone, and now football.
The first match to be shown on the trial was the world cup match between Columbia and Uruguay (live).
A quarter final match, a semi final match and the World Cup Final will be shown here over the next ten days or so.
The BBC have also announced an extension to this service, to take place during the Commonwealth Games, where the trial will be on public display in various locations.

sadly many people have been caught up in this deliberate overhype of technology.
4k over 1080p probably for the human eyes unless a very large screen is not noticeable.  The reason those streams would look great is the bitrate and encoding.
Same way as in SD was great in the analogue tv days as was no compression.
Watch raw SD footage and you be amazed how good it looks.
Everytime resolution is increased is diminishing returns, and I think from 720p onwards that very much applies.

I can see the difference between 720 and 1080, but I cant really see any difference between 1080 and 4k unless its a monitor in which case you can but the larger screen at the close distance means you miss half of whats going on anyway so its not much good.
I do wish however I'd kept my old crt tv instead of selling it to a mate for £50 when he was desperate for something old style (so his autistic kid couldn't smash the screen again) as it was definably much better for watching the old SD stuff on .... then again he needed that after his home insurance jumped through the roof off the back of 5 flat screens trashed in month ....
just because your paranoid doesn't mean they aren't out to get you
