Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the SCC Mirror Committee (SMC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T).
This Recommendation International Standard defines a set of lossless (bit-preserving) and lossy compression methods for coding bi-level, continuous-tone grey-scale, palletized colour, or continuous-tone colour digital still images.
This Recommendation International Standard:
- specifies decoding processes for converting compressed image data to reconstructed image data;
- specifies a code stream syntax containing information for interpreting the compressed image data;
- specifies a file format;
- provides guidance on encoding processes for converting source image data to compressed image data;
- provides guidance on how to implement these processes in practice.
NOTE - As this specification was first published as common text only after ISO/IEC HCI had approved the first edition in 2000, edition numbers in the ITU and ISO/IEC versions are offset by one. This is the second edition of ITU-T T.8OO and the third edition of ISO/IEC 15444-1.
