Rec. ITU-T H.222.0 | ISO/IEC 13818-1 was developed in 1994 to principally support the combination and synchronization of video and audio coding methods defined in ISO/IEC 13818 Part 2 (Rec. ITU-T H.262) and Part 3. It has since then been extended to support additional video and audio coding specifications as well as multiple kinds of metadata. This corrigendum corrects numerous errors in H.222.0 (2018) and its Amd.1 and Cor.1. It is planned that this corrigendum NOT be published separately, but integrated in a new 9th edition of the specification.
