ITU-T T.809-2007 发布历史

ITU-T Recommendation T.809 | ISO/IEC 15444-10 is a work item subdivision of ISO/IEC 15444 that provides extensions of ITU-T Recommendation T.800 | ISO/IEC 15444-1 and ITU-T Recommendation T.801 | ISO/IEC 15444-2 for logically cuboidal data sets. In particular, it respects all existing capabilities and syntax of ITU-T Recommendation T.800 | ISO/IEC 15444-1 and part of the existing capabilities of ITU-T Recommendation T.801 | ISO/IEC 15444-2 for multi-component images, while providing alternatives and extensions to some of those capabilities. Within these constraints, it provides an isotropic specification for three-dimensional data sets; i.e., the project provides identical processing capabilities in all three dimensions even though ITU-T Recommendation T.800 | ISO/IEC 15444-1 and ITU-T Recommendation T.801 | ISO/IEC 15444-2 codestream syntax differentiates between the two spatial axes and the cross-component axis. The context models currently used in this Recommendation | International Standard are as in ITU-T Recommendation T.800 | ISO/IEC 15444-1 and ITU-T Recommendation T.801 | ISO/IEC 15444-2. Improved context models will be introduced through an amendment.
