      Sky 4K not too far away??

      Just seen this article:
      Sky tests 4K Ultra HD live football transmission: West Ham vs Stoke City

      4K looks like a really promising technology. I would rather have 4K than 3D. What does everyone else think?

      Bearing in mind we still pay 10pm for HD many years after HD launched, how much do you think we would be charged for 4k. What size tv would you actually need before you could appreciate the improved quality of 4k. Can't see it taking off for residential customers.

      they should concentrate on 1080p instead ,skys hd is pitiful at times you can get a 1080p torrent that has no posturization in mkv format thats a much smaller size than the mpeg4 that sky insists on using and usually with DTS too
      sky need to come into the modern world

      i for one wont be falling for this 4k crap -so ive now got to buy all my films again and a new player and guess what in a few years time it will be 8k then 16k blah blah blah -....end of rant....

      Re: Sky 4K not too far away??

      It is predicted that the UK will be getting 4K transmissions during 2015.

      Now that both the BBC and Sky are working together on this, it should be quite possible. However I can't see it being possible over Freeview with the current frequency issues.

      That leaves Broadband or Satellite.

      HD transmissions can require 25mb/s transmission speed. I'm not sure what a 4K transmission would require. Whilst I personally may be fine some of the time, I think that many others would struggle. If there is more than one UHDTV in the home, then it would be a real issue with current broadband speeds.

      As for the Satellites, I would expect someone in Sky to be working very hard to produce a whole new Sky STB which can support 4K UHDTV.

      As for the 8K transmissions, these are predicted to be showing around 2020.

      Re: Sky 4K not too far away??

      To make 4k a worthwhile viewer experience you will need a very big screen or sit ridiculously close to a smaller screen. Big screens are expensive for 1080p so what will they cost for 4k? Whilst 4k has some attractions the entry cost for many/most will be too high in the short/medium terms. On top of that you have the technical issues involved with data transmission over satellite or broadband. So it seems like a long term development for most potential users whilst a few will spend the high sums involved to be an early adopter.

      The current boxes do h264 MPEG4 decoding.

      The new 4K broadcasts will need new hardware which is capable of h265 MPEG4 decoding.
      Now this won't be possible with existing hardware as they are a bit poo at existing standard (my box runs very hot!) and the HDMI will need to be upgraded too.

      Does the existing box have hardware h264 decoding?
      It seems to run very hot compared to my Raspberry pi which does the same.

      They need to build a new chipset which does h265 decoding on chip, in an optimised way so there isn't a high power usage penalty.

      From the people that have seen this new standard though, it seems that 3D isn't required for this new standard to give realism. However in 4K it does allow full frame 1080 resolution in 3D, even with passive technology which is where the home 3D market seems to be heading due to flicker (and expense) issues with active 3D glasses.

      Sky needs to bring out a box capable of 4K and maybe 8K as this will likely be the last big push for traditional tv broadcasting. Everything seems to be moving online, especially as UK connection speeds improve.

      Do the existing satellites have any bandwidth left for 4K TV? The way things are going, it's debatable whether set top boxes will even be necessary soon, when you can just have one media server wirelessly streaming to any number of devices.

      Having just won the rights to some transponder frequencies, I suspect that Astra will have quite a lot more bandwidth to sell to their customers.

      Its good to see "commercial" companies starting early "real life" tests with technology but lets face it - it's just as much about PR & company image "flexing" as it as about the technology at this stage (look at 3D).

      The "arms" race to double the pixel density every 5 years because "we can" sounds a lot like the microprocessor industry's "Mores Law" which served one company / technology extremely well but wasn't necessarily in the interest of the consumer.

      In the opinion of this humble TV viewer Sky's investment in content linking to seamless quality social media & non linear delivery is more important right now to get a jump / foot hold to fight off the likes of Google/Apple/Yahoo. Look arround your living room at those watching TV - I bet we have a few eyes on tablets / laptops at the same time as tradition TV viewing.

      I'm sure Sky has got the message that to grow you need to be bigger than the sum of your "rights buying" budget. BT is a wake up call to that.

      Sure BT is attacking Sky's dominence, which is understandable.

      Sky have been making waves into the Broadband and telephone market, which VM and TalkTalk have also been doing. BT has therefore decided to get serious about pushing out their TV side.

      However as to the picture quality from 4K and 8K TV, it is decidely better than HD TV (1080p).

      Over the years since 1936 the picture quality has improved from 405 lines, which was black and white, to what we have today. Sure not everyone can benefit and the new TVs cost a lot of money, as did HD (1080p) TVs when they were first launched.

      Remember that all the new films in the Cinemas are shown in 4K and have been for a few years now. This means that there will be plenty of film content readily available when 4K UHDTV is launched. As for 8K UHDTV, this will require even more bandwidth for the transmissions and is probably as good as our eyes can handle.
