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 Canadian Advisory Committee (CAC) 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

A number of image and video coding related standards (see Bibliography) include a requirement for decoders to implement an integer-output 8x8 inverse discrete cosine transform (IDCT) for the generation of inversetransformed sample differences with a nominal range from -2B to (2B)-1 for some integer number of bits B, where B is greater than or equal to 8. This part of ISO/IEC 23002 specifies conformance requirements for establishing sufficient accuracy in such an integer-output IDCT implementation. It is intended to be suitable for reference to establish partial or complete requirements for IDCT accuracy for conformance to other standards that require IDCT use.

The accuracy requirements specified in the main body of this part of ISO/IEC 23002 are essentially the same as those previously specified in [7], in Annex A of [1], and in Annex A of [5]. These requirements have been specified herein to resolve normative references to [7] in MPEG standards after its withdrawal and to provide improved clarity for the specification of IDCT accuracy requirements.

An additional requirement on encoded-bitstream intra refresh frequency was also previously specified in [7], establishing a requirement of bitstream conformance that each macroblock be intra-coded at least once within each series of 132 times that it is coded in a predicted picture without an intervening intra picture. That additional requirement is not specified in this part of ISO/IEC 23002, in order to confine its scope to the domain of decoder conformance specification.

Some allowances for modification of the specified accuracy requirements are made within this part of ISO/IEC 23002. Additional accuracy requirements that may be invoked by a referencing specification are specified in Annexes A and B.
