Using UMID Data
To perform operations from interviewing to editing 
effectively and to detect audio-visual materials easily 
when reusing them, metadata that provides additional 
information is recorded along with audio-visual data on a 
disc.
As one of application of metadata, the UMID (Unique 
Material Identifier) is internationally standardized.
What is a UMID?
The UMID (Unique Material Identifier) is a unique 
identifier for audio-visual material defined by the 
SMPTE330M-2003 standard.
The UMID may be used either as the 32-byte Basic UMID 
or as the Extended UMID, which includes an additional 32 
bytes of Source Pack to make a total 64 bytes.
For details, refer to SMPTE 330M.
Globally unique ID is automatically recorded every 
shooting.
The Extended UMID is metadata that provides additional 
information such as location, time/date, company and so 
on.
The UMID is applied as follows.
Using the Extended UMID
You have to enter a country code, organization code and 
user code. Set the country code referring to the ISO 3166 
table, and set the organization code and user code 
independently.
