SMPTE ST 381-2

Description

SMPTE ST 381-2 – Material Exchange Format (MXF) – Mapping MPEG Streams into the MXF Constrained Generic Container

This standard specifies the mapping of video and audio MPEG ES, as identified by an ISO/IEC 13818-1 stream_id value, as well as the carriage of data streams extracted from higher level MPEG multiplexes, into the MXF Generic Container described in SMPTE ST 379-2. This includes, but is not limited to, ISO/IEC 13818-2 MPEG video stream, ISO/IEC 11172-2 MPEG video streams, ISO/IEC 14496-2 MPEG visual streams, ISO/IEC 14496-10 video streams, ISO/IEC 13818-3 MPEG audio streams, ISO/IEC 11172-3 MPEG audio streams, and ISO/IEC 14496-3 MPEG audio streams. It does not include ISO/IEC 14496-15 video streams. The document outlines single stream mapping and synchronized multi-stream mapping along with synchronization requirements for the MXF encapsulation of co-timed MPEG Essence streams. This standard defines SMPTE universal labels to be used to uniquely identify specific MPEG implementations. The Essence Element Keys and an Essence Container Label for MPEG streams are detailed along with CBE and VBE indexing of MPEG content using Index Tables. In order to achieve interoperability within any given Operational Pattern, restrictions may be placed on the way in which this Essence Container can be implemented. The reader is advised to carefully study the appropriate Operational Pattern document before implementation.
