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.
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.
UMID with a Basic section only is called a Basic UMID. 
UMID with both Basic and Source Pack sections is called 
Extended UMID. The figure below gives a general 
overview of the information contained in a UMID.

UMIDs can be recorded when recording video signals with 
this unit. You can select whether to inherit (copy) the 
UMID contained in input signals automatically or forcibly 
generate a new UMID.

Select whether to record Basic UMID or Extended UMID, 
using setup menu item 655.

When recording UMID, you can select whether to inherit 
(copy) UMID contained in input signals, or generate new 
UMID. Make this selection by using setup menu item 656.

If you choose to inherit UMID contained in input signals, 
almost all of the information in the UMID is copied 
without change, but the Instance Number changes to a 
value that indicates that “this UMID is a copy.” The new 
value can be generated from a 16-bit pseudo-random 
number with the addition of the number of copies (1 byte), 
or it can be generated from a 24-bit pseudorandom 
number. Select the method used to generate the Instance 
Number by using setup menu item 654.

You can select the VANC (Vertical ancillary) line into 
which the generated UMID should be inserted. Make this 
selection by using setup menu item 653.
