The ITU-T Newslog has a post on ITU's standards work on large screen digital imagery (LSDI), a family of digital imagery systems that includes very large screen presentation of programmes similar to the non-digital IMAX and OMNIMAX systems. LSDI is described as an optimal approach to the presentation of high-definition television (HDTV) programmes, to a collective audience on cinema-like screens in a cinema-like environment.

An ITU-T Recommendation defines how "super HDTV" images up to four times the quality of standard HDTV - can be delivered to cinema-like venues, bypassing traditional distribution methods. It defines transport technologies for LSDI with resolutions 3840 x 2160 and 7680 x 4320 pixels.
