Technologies de l'information — Technologies des systèmes MPEG — Partie 9: Cryptage commun des flux de transport de contenu MPEG-2

ISO/IEC 23001-9:2016 specifies a common media encryption format for use in MPEG-2 transport streams. This encryption format is intended to be used in an interoperable way with media encrypted using the format described by ISO/IEC 23001‑7. ISO/IEC 23001-9:2016 allows conversion between encrypted MPEG-2 transport streams and encrypted ISO base media file format files without re-encryption.
