5 Chapter UMID Functions Chapter 5 UMID Functions 5-1 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 generation of UMIDs recorded in the Digital Betacam or MPEG IMX format. 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.
