标准摘要
ISO/IEC 23001-9:2014 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 23001-9:2014 allows conversion between encrypted MPEG-2 transport streams and encrypted ISO base media file format files without re-encryption.
