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.

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 94.

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.
