lchiu7: If you had read the article about all the technical challenges the BBC had in streaming the World Cup in 4K then you would have seen that despite having a fast fibre connection to your home, that is only the tail end of the distribution. The BBC had to limit the streams to 60K users they said.

 

http://www.bbc.co.uk/blogs/internet/entries/5c5b8f80-891d-4b51-babd-8814c1511b4e

 

"We decided we’d be comfortable with a maximum number of around 60,000 concurrent UHD viewers, but that the number would be continually re-assessed during the tournament depending on overall performance. We also estimated there were maybe 2 million devices that might be capable of playing the UHD streams, hence the warnings about the streams being available on a first come, first served basis."

 

If you can receive the OTA signal, then that's got to be a more reliable delivery mechanism and not relying on such much infrastructure.

 

 

Conversely, Sky/Vodafone's TV over fibre offering shows that it's possible to distribute to many customers via multicast. You don't get on-demand features this way, but for live broadcasts it removes most of the strain from the network.

Just performed a re-scan on my Samsung TV (late 2015) and found the UHD channel 201.

 

Picture was slightly more detailed, not overly sharp but seems to have less noise. Some 4K Youtube looks sharper, but maybe due to 'sharpening' filter on the source.

Hi guys. I'm the author of a Windows TV app called NextPVR. I'd like to try these signals out, to check they're compatible with my app, but unfortunately I'm in Wellington.

 

Is there someone up there that could capture 1 minute file transport stream, and put it somewhere like dropbox or onedrive, and let me know the download link? On Windows you easily capture it using the evaluation version of TSCapture from http://tscapture.com (which is another app I wrote).

PM me if no one responded, I've got MediaPortal on my home pc that records .ts file.

Is anyone able to link to a MediaInfo full text output for a 1min or so sample? Am interested to know some technical details about what is being broadcast.

I wish we would get a trial down here in Christchurch!

 

 

 

Fingers crossed we get a 4k channel on DTT in the next year....

 

 

 

 

I am really loving 4K HDR!! So far on Netflix, Youtube and gaming....

Out of curiosity, is the stream test an implementation of this? https://www.tvbeurope.com/business/uhd-1-phase-2-approved

Rather disappointed with the video being shown. Lots of brief pauses, jumps in zoom and slow motion scenes, make it difficult to detect when frames are dropped/duplicated.

 

Playback on my Vero 4k with tvheadend on the backend is not quite as smooth as I would like, although I am seeing similar issues with Kodi on my desktop to a lesser extent. Recordings seem to be a bit better.

 

The Vero 4k only has a 100Mbs^1 Ethernet port, and I use iSCSI for recordings and the timeshift buffer, so there are areas I could improve if 4k TV actually becomes a thing. I'm not convinced of the need for it. Who watches their TV from a distance where it would actually make a difference?

Me. There's more to it than that, higher frame rates, e.g., 100 fps on broadcast and HDR is what I want to see.

I'd rather get all the existing channels in 1080p before worrying about 4K.

You won't get that without the move to DVB-T2 though - since existing providers adding additional MUXs costs $$$
