Unique Material Identifier

The Unique Material Identifier ( UMID ) is a standard (SMPTE 330M ) to generate unique identifiers (IDs) of multimedia files and data streams.

The length of a UMID is 32 bytes ( Basic UMID ) or 64 bytes (Extended UMID ). The Basic UMID is intended only for the clear identification. The Extended UMID also contains data on the location, the time and the creator.
