Recommendation ITU-T T.832 specifies a coded image format, referred to as JPEG XR, which is designed primarily for the storage and interchange of continuous-tone photographic content. The main body of the text specifies the syntax and semantics of JPEG XR coded images and the associated decoding process. Annex A specifies a tag-based file storage format for the storage and interchange of such coded images. Annex B specifies profiles and levels that determine conformance requirements for classes of encoders and decoders. Aspects of colour imagery representations and colour management are discussed in Annex C. The typical expected encoding process is described in Annex D. The first edition of Recommendation ITU-T T.832 was approved in 03/2009. Corrigendum 1 (approved 12/2009) contained a set of various minor corrections. Corrigendum 2 (approved 05/2011) contained additional minor corrections. The second edition (approved 01/2012) included additional minor corrections. The third edition (approved 08/2016) added a media type specification for use in various Internet protocols to identify images encoded according to the tag-based format specified in Annex A of this Recommendation. This fourth edition (approved 06/2019) adds the specification of support for additional colour formats, support for an alternative file storage format based on ISO/IEC 23008-12 and associated media type specifications for the storage and interchange of JPEG XR coded images and image sequences. This text was developed as a twin text Recommendation corresponding to ISO/IEC 29199-2 in collaboration with ISO/IEC JTC 1/SC 29/WG 1 (JPEG).
