8K video: Easily doable on gigabit-over-copper G.fast broadband

[jos]

Early tests of G.fast undertake by BT demonstrated download speeds of around 700Mbps and uploads of 200Mbps on the most common types of copper lines.BT’s trials were however based on an early, non-standardised version of G.fast. Now the standard's been defined the technology can, potentially, deliver faster speeds to more customers.The ITU says that G.fast will allow for next-generation streaming services, HD Skype video calls and advanced cloud-based services to operate without a hitch.Telecoms technology standards body the ITU (International Telecommunication Union) rubber-stamped the standard on December 5, meaning hardware manufacturers can start cranking out chipsets now. International industry consortium the Broadband Forum says it will kick of its first plugfest in January 2015, letting ISPs see which kit works best for them.

8K is doable on a 10 Mbps connection. Albeit at a 10 Mbps combined bitrate. The resolution has nothing to do with the file size.

The next few years in technology are going to be very exciting.

yeah m8s, i enjoy having to live right next to the telephone exchange to use my service to it's full potential

8k could be done on much lower speeds using H265

 

 

NHK recently carried out successful testing of 8K (7680x4320) broadcasting over a distance of 27 kilometers with a single UHF channel. NHK used the HEVC codec as compression and a bit rate of 85 Mbit/s

So is that bit rate very low and bad ?

yeah, that's why youtube 4k just looks like high bitrate 1080p lol

  according to NHK thats roughly six to ten times more than most 720p TV channels are using for bit rate

So it's good for 8K video or low ?

for TV its great

u would need ~85mbps connection to play at the bitrate NHK had

but  this is H265 which means if it was at H264 it would be around  130Mbps - 160Mbps

 

also netflix's house of cards which is at 4k H265  is at only a mere 15.6 Mbps

I will still need faster internet connection and no data caps

Resultion is absolutely affects the file size.

 

Factors that affect video file size:

Resolution

Color quality (color bit depth)

Bit rate

audio quality/bit-rate

 

Compression algorithms generally will hit various aspects of the video in order to reduce the file size.

This won't mean much when Comcast get its way...

The video bitrate, color depth, audio bitrate, audio sampling rate, audio bit depth affect the size, as well as codec of course.
