It also identified a number of challenges towards UltraHD that I lay out here again:
- Lack of Agreed technical standards
- Equipment investment costs and increased operating costs of bandwidth and storage for content
- Fear of causing consumer disaffection and failure similar to the 3D debacle through the launch of non-backwards compatible devices
- Sufficient installed base of suitable TVs
We are now returning to look at these areas as sufficient time has passed for developments to have taken place and we will look at the updates over a number of blog posts in the coming weeks as you settle down towards a little bit of vacation time.
UltraHD has become a little more defined since we looked into it last and it pays to summarise it here before the next post, and now it can be clearly defined under four distinct pillars – 4K, HDR/WCG, HFR and NGA – with UHD using one, two or more of these pillars.
- 4K – The simplest thing to understand, the resolution, which has very much settled into the 3840×2160 pixel resolution.
- HDR/WCG – High Dynamic Range and Wide Color Gamut – made possible by the use of a new color model (BT.2020) and Electro-Optical Transfer functions (ST 2084/HDR-10/HLG), distribution use of 10bits precision, and the introduction of higher brightness screens.
- HFR – High Frame Rate, beginning with a baseline of 50/60fps and moving upwards as technology and content allows
- NGA – Next Generation Audio which is the introduction of non-channel based, object oriented high quality audio delivery.
In our next posts, we will look into how things have moved forward in terms of the opportunities and challenges that we saw back at the beginning of 2015.
