Corrigendum 1 to Recommendation ITU-T H.222.0 | ISO/IEC 13818-1 removes the constraint on use of zero_byte syntax element, as it is specified in the latest version of Rec. ITU-T H.264 | ISO/IEC 14496-10. This correction is needed to avoid conflict between Rec. ITU-T H.222.0 | ISO/IEC 13818-1:2007 and Rec. ITU-T H.264 | ISO/IEC 14496-10.
This corrigendum also corrects several errors in the use of stream_id_extension mechanism, both in the PES header byte-alignment and for applications that use program streams (such as DVD). This corrigendum adds a backward compatible mechanism to signal the stream_id_extension in System Header, Program Stream Directory and Program Stream Map.
Compatibility is maintained with the earlier versions of MPEG-2 systems as well as deployed applications (such as HD‑DVD).
