SMPTE Metadata Registers Documentation
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:
| Register | Engineering Document |
|---|---|
| Labels | SMPTE ST 400:2012 |
| Types | SMTPE ST 2003:2012 |
| Elements | SMPTE ST 335:2012 |
