5-3-10 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
tape. 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.
For details, see “UMID menu setup” on page 102.
Functions of UMID data
The UMID data enables the following:
• Add a globally unique ID to every shot 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.
