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.
• Defining the user who created the material source based on recorded
Ownership
Recorded ownership allows you to define the organization owing the
source material and identify the user who created the video image.
You can select whether the ownership is recorded or not.
• 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.
A unit in which an HKDW-704 has been installed generates the
universal time based on the GPS satellite clock, and a unit without an
HKDW-704 generates the universal time using the built-in clock and
the time zone.
• 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.
A unit in which an HKDW-704 has been installed generates the MJD
based on the GPS satellite clock, and a unit without an HKDW-704
generates the universal time using the built-in clock and the time zone.
• Recording location information (latitude, longitude and altitude)
The location information can be recorded. Based on this location
information, shooting location is specified or source material is
managed according to the shooting location or area. (Only for a unit
with an HKDW-704 GPS unit)
