This standard provides detailed specifications for the precision requirements of integer inverse discrete cosine transform (IDCT) in the context of MPEG video technology. It focuses on the implementation of an 8x8 integer IDCT and outlines the necessary accuracy criteria to ensure consistent performance across different systems. The document includes guidelines for testing software that validates the compliance of integer IDCT implementations with the defined precision levels. It serves as a reference for developers and engineers involved in the design and verification of video coding technologies. The standard also addresses the testing procedures and criteria for ensuring that the implemented algorithms meet the required accuracy standards. It is structured to support the development of reliable and interoperable video coding solutions.
