ITU-R BT.1728-1 1 RECOMMENDATION ITU-R BT.1728-1 Guidance on the use of flat panel displays in television production and postproduction (Question ITU-R 95/6) (2005-2010) Scope This Recommendation provides upda
9、ted guidelines on the use of flat panel displays in the professional television programme production/postproduction environment. The ITU Radiocommunication Assembly, considering a) that flat panel displays are now being used for reasons of availability in television broadcasting, for various applica
10、tions, including professional programme production/postproduction ones; b) that flat panel displays may be used with advantage in television programme production/postproduction operation, e.g. in outside broadcast vans and in studios, where they can display large images within a package of reduced b
11、ulk and weight; c) that at the present stage of technology development, flat panel displays present images whose rendition depends on the type of technology used in the flat panel, and often also depends on the display brand and model, even for displays that use the same flat panel technology; d) th
12、at flat panel displays are often adjusted to present images at a higher colour temperature than the standardized one, so that images typically appear “colder”; e) that flat panel displays typically use some pre-processing that can lead to images being displayed with spatial or temporal artifacts; f)
13、 that the image rendition of some flat panel displays depends on the angle under which the display is viewed; g) that the technology of flat panel displays is developing at a fast pace, and one may expect some performance improvements in future flat panel displays, recommends 1 that the arbitrary us
14、e of any make or model of flat panel display should be avoided in television programme production/postproduction applications, notably in those applications in which a reliably correct and uniform image rendition is required, such as in control rooms and viewing rooms, where television images are ba
15、lanced and matched and where programme quality is checked and certified; 2 that in television production rooms and control rooms, image quality should be monitored on a professional cathode-ray-tube (CRT) studio monitor, if available, or on a professional flat panel display of a brand and model whic
16、h has been checked in advance to reasonably match the performance of a CRT studio monitor; 2 Rec. ITU-R BT.1728-1 3 that, whenever flat panel displays are considered for possible use in other television programme production/postproduction applications, their performance should first be tested to be adequate for the envisaged application.
