7-1 Overview of UMID Functions
The UMID (Unique Material Identifier) is a type of
meta-data in video and audio materials. It has been
internationally standardized in SMPTE Standard
330M. This unit supports recording and generation of
UMIDs.
The UMID is made up of a section called the “Basic”
section and a section called the “Source Pack” section.
The Basic section contains information such as the
device that recorded the material and whether the
material is the original or a copy. The Source Pack
section contains information about when/where/who
recorded the material.
A UMID with a Basic section only is called a Basic
UMID. A UMID with both Basic and Source Pack
sections is called an Extended UMID. The following
figure shows a general overview of the information
contained in a UMID.
