CSA Group Information technology - MPEG video technologies - Part 2: Fixed-point 8×8 inverse discrete cosine transform and discrete cosine transform CAN/CSA-ISO/IEC 23002-2:18

CSA Preface 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). Scope This part of ISO/IEC 23002 specifies a particular implementation of an integer-output 8×8 IDCT that fully conforms to the accuracy requirements specified in ISO/IEC 23002-1 (see Ref. [7] in the Bibliography) and additionally meets or exceeds all accuracy requirements specified for IDCT precision in a number of international video coding standards (see Ref. [2] to [6] in the Bibliography). It additionally provides a (non-normative) specification of an integer-output 8×8 forward DCT based on the same factorization structure.
