In this era of rapid technological change, it is widely recognized that international standardization and coordinated planning for the introduction of new systems and services assume critical importance. The rapid acceleration in the work leading to the introduction of advanced television systems such as HDTV provides an important example in the way in which the CCIR has responded to the challenge of change through the identification of the processes and decision-making mechanisms necessary to produce timely and coordinated action for the development of HDTV studio, emission and transmission standards. This report contains the conclusions of the ITU's Extraordinary Meeting of Study Group 11 on High-Definition Television.



Draft Report AQ/11 – Recording of high-definition television programmes on cinematographic film

The use of HDTV to produce films for the international exchange of television programmes and for other uses, such as direct projection in the cinema, is of increasing importance. The intrinsic high quality of the HDTV image, and the accompanying sound, allows film recordings of high quality for programme exchange. The development 9f the methods to perfarm this transfer with a low level of impairment is advancing rapidly. This equipment must include both image processing, to adapt the video signal to the film emulsion characteristics, and transformation from the HDTV scanning parameters to those of conventiona mmfilm. In particular, frame rate converters may be necessary, which require sophisticated processing. The equipment must also include high quality sound recording capability
