Chris Johns of the UK's BSkyB, said that the operator of pay-TV platform has no plans to close Ultra HDTV, but it closely examines the options for delivery of television technology in the future. Johns stressed the need for testing, so that when you run 4K everything was buttoned up.

- There are no plans to start the service UHDTV in the near future - Johns said at a conference in London Beyond HDTV. - It's still very early days yet. The HD went through a period of 2 years of testing. In the 3D was 18 months. We are still at an early stage, and when we are able to provide something "more than HD," we want to do it in the highest possible quality.

One of the main challenges to overcome for BSkyB was the parameter frames per second. - All available 4K displays that we use are 30 Hz, or worse, while we need at least 50 fps for sports and probably more - said Johns.

He explained that in the past eight years Sky has evolved from a standard delivery model to HD, with small screens to large, from 2D to 3D and from basic to advanced compression codecs.

- If we are unable to provide UHDTV in 2014, it would be great - he added. - But there are many problems to be solved. The question for today is how far we have come with some of these items for the next generation of visual experience for the customer.
