1、QUESTION ITU-R 40-1/6*Extremely high-resolution imagery (1993-2002-2010) The ITU Radiocommunication Assembly, considering a) that TV technology at a number of levels of quality may find applications in both broadcast and non-broadcast services; b) that the Radiocommunication Sector is studying a ran

2、ge of TV systems for broadcast uses; c) that ITU-R has been studying extremely high-resolution imagery and expanded hierarchy of large screen digital imagery, and has established Recommendations ITU-R BT.1201-1 that provides the guideline of image characteristics for extremely high-resolution imager

3、y and ITU-R BT.1769 that provides the parameter values for expanded hierarchy of image formats for LSDI applications; d) that HDTV technology along with large screen displays has become the norm in homes, where audiences enjoy high-quality programme content; e) that progress in display technologies

4、will permit the use of large-screen and extremely high resolution television displays for home viewing; f) that additional visual experiences beyond HDTV can be offered by presenting higher resolution images, which can give a stronger sensation of reality to viewers; g) that broadcast applications w

5、ith such a feature, called ultra high definition television (UHDTV) can be considered as one of the forms of extremely high-resolution imagery; h) that some administrations consider introducing broadcasting of UHDTV to the home associated with improved efficient coding and transmission technologies;

6、 j) that in some broadcast-related applications (for example: computer graphics, printing, motion pictures) an extremely high resolution is expected; k) that studies on higher resolution digital image architecture are being conducted in some organizations, _ *This Question should be brought to the a

7、ttention of the International Electrotechnical Commission (IEC), the International Organization for Standardization (ISO) and the Telecommunication Standardization Sector. - 2 - decides that the following Questions should be studied 1 What kind of approach should be taken to realize such an extremel

8、y high-resolution imagery system for broadcasting and non-broadcasting applications? 2 What features such a system should have to allow for broadcasting applications and to assure harmonization between different applications? 3 What kind of parameters should be determined for these systems in progra

9、mme origination and exchange? 4 What characteristics should be recommended in every part of the TV broadcasting chain using extremely high-resolution imagery, namely acquisition, recording, contribution, distribution, emission and display? NOTE 1 See Reports ITU-R BT.2042-3 and ITU-R BT.2053-2; see also Question ITU-R 15-2/6. further decides 1 that the results of the above studies should be included in (a) Report(s) and/or (a) Recommendation(s); 2 that the above studies should be completed by 2012.
