About the SMPTE Metadata Registers

The SMPTE Metadata Registers are catalogues of metadata items identified by SMPTE Universal Labels – these are typically used in applications of Key-Length-Value (KLV) coding such as MXF audio-visual files.

The SMPTE Engineering Documents that define the SMPTE Metadata Registers are known as the Metadata Register Structure Documents. These provide the formal definition of the SMPTE Metadata Registers. The relevant documents are:
