MENDATION ITU-R * munication Study Group 6 made editorial amendments to this mendation in 2002 in accordance with Resolution ITU-R 44.
Extremely high resolution imagery
(Question ITU-R 226/11)
(1995)
The ITU munication Assembly,
considering
a) that extremely high resolution imagery could be used as future imaging systems in various fields, such puter graphics, printing, medical, motion pictures, television and so on;
b) that for constructing such systems, it is necessary to consult with many experts in various related fields on images;
c) that studies and application experiments on extremely high resolution imagery are being conducted in various parts of the world;
d) mon usage of devices is preferable for economical implementation of the extremely high resolution imagery systems;
e) that bit-rate reduction technologies take a major role in transmission of the extremely high resolution imagery;
f) that required spatial and temporal resolutions and aspect ratios may differ depending on the applications in the market place;
g) that conversion of spatial and temporal sampling lattices are ing possible between different formats without introducing artifacts to the converted images,
mends
1 that spatial and temporal resolution and picture aspect ratio should be flexible enough to meet a variety of requirements in different application fields. Annex 1 gives examples of current development work;
2 that a header in the data stream should be used to define the parameters specified in § 1 above;
3 monality of colorimetry should be achieved in different formats.
ANNEX 1
Progress report on extremely high resolution imagery (HRI)
1 Introduction
Because of the physical limitations in technologies which are available in the real world, most of the applications described in this mendation are in non-real-time areas. To investigate realization issues in § 3 a model has to be assumed. Because of the reasons listed above, in spatial resolution hierarchy, th
