What is a UMID?

The UMID (Unique Material Identifier) is a unique

 

The UMID may be used either as the 32-byte Basic UMID

identifier for audio-visual material defined by the

 

or as the Extended UMID, which includes an additional 32

SMPTE330M-2003 standard.

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 “About UMID ownership information” (page 111).

Functions of UMID data

The UMID data enables the followings:

•Add 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.

•Recording based on the UTC. The UTC is used when recording the UMID. This enables uniform control of source material recorded all over the world based on the universal time code.

•Calculating the date difference among source materials. The source material is recorded based on the MJD (Modified Julian Date), which enables easy calculation of date difference among source materials.

Setting UMID ownership information

Proceed as follows.

1 Set extended menu item 029 “STORED OWNERSHIP” to “on.”

See 7-2-2 “Basic Menu Operations” (page 94) for more information about how to make this setting.
