4K image transfer and HDMI 2.0

To playback 3D 4K videos, a TV has to be able to produce at least 60 frames per second (fps), however, HDMI 1.4 is only able to produce a maximum of 30fps. There are two solutions to this, the implementation of HDMI 2.0 or a little trick used by many manufacturers: film data is projected via HDMI 1.4 in the 4:2:2 colour space with 12- Bit colour depth even if it is available as 4:2:0 with eight-Bit, like on a Blu-ray. 4K HDTVs will be receiving firmware updates for the 4:2:0 transmission via HDMI 1.4.
