Using UMID Data
Appendix
Using UMID Data
Metadata is additional information recorded on media
along with audio-visual data. It is used to bring greater
efficiency to the flow of operations from material
acquisition through editing, and to make it easier to find
and reuse material.
As one of application of metadata, the UMID has been
internationally standardized.
What is a UMID?
A UMID (Unique Material Identifier) is a unique identifier
for audio-visual material defined by the
SMPTE-330M-2004 standard.
A UMID may be either as a 32-byte Basic UMID or an
Extended UMID, which includes an additional 32 bytes of
Source Pack to make a total 64 bytes.
For details, refer to SMPTE-330M.
A globally unique ID is automatically recorded for every
clip.
The Extended UMID is metadata that provides additional
information such as location, time/date, company ID 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 table in ISO 3166, and
set the organization code and user code according to the
guidelines of your organization.
For details, see “Setting UMID ownership information”
(page 146).
Functions of UMID data
UMID data enables the following:
•
Addition of a globally unique ID to every clip of audio-
visual material. The unique ID is used to detect the
material source and to link it with the original source
material.
•
Distinguishing between original material and copied
material. 00 is added to the Instance Number for original
material.
