The ITU Radiocommunications Assembly considering a) that new very high resolution, LSDI are being introduced in some countries, whereby dramas, plays, sporting events, concerts, cultural events, etc., photographed electronically or on film, can be delivered, and exhibited in high resolution quality in theatres, halls, and other venues equipped with digital imaging capabilities; b) that such practice has the potential to produce excellent picture quality, equal or superior to that available heretofore, and opens the possibility for program delivery in various digital forms for exhibition to large audiences; c) that such practice is reported to also offer significant benefits in terms of a faster, lower cost production/postproduction and distribution, including to smaller, less-developed markets; d) that high resolution, bright, large screen projection equipment is available from several international manufacturers; e) that it may be beneficial to develop a uniform or compatible hierarchy of technical standards for program recording, mastering 3 , exchange, delivery and exhibition, harmonized with those established for the recording and mastering, exchange and delivery of programs for other applications, since this can ease international program exchange; f) that the ITU-R has been studying extremely high resolution imagery under Question ITU-R 40/6 based on the concept of a tiered or hierarchical approach.
