8-2 Recording UMIDs
UMIDs can be recorded when recording video signals
with this unit. You can select whether to inherit (copy)
the UMID contained in input signals, or automatically
or forcibly generate a new UMID.
Selecting the type of UMID to record
Select whether to record a Basic UMID or an Extended
UMID by using setup menu item 655 UMID
RECORDING.
See page 12-18 for more information about setup menu item
655.
Selecting whether to inherit or generate
the UMID
When recording a UMID, you can select whether to
inherit (copy) the UMID contained in input signals, or
generate a new UMID. Make this selection by using
setup menu item 656 MATERIAL NO.
See page 12-19 for more information about setup menu item
656.
Selecting the Instance Number generation
method when inheriting UMIDs
If you choose to inherit the 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 which 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 pseudo-random number. Select the method
used to generate the Instance Number by using setup
menu item 654 UMID GENERATE METHOD.
See page 12-18 for more information about setup menu item
654.
Selecting the SDI VANC line to insert the
UMID
You can select the VANC
1)
line into which the
generated UMID should be inserted. Make this
selection by using setup menu item 652 UMID SD
VANC LINE.
See page 12-18 for more information about setup menu item
652.
Note
UMID data in the input signal may not be readable if
the line where UMID data is inserted into SDI input
signals is the same as the line where this unit inserts
VITC (setup menu item 601 (page 12-16) and setup
menu item 602 (page 12-16)), or if that line is subject
to blanking (setup menu item 723 (page 12-24)). In
cases like these, change the setup menu settings.
To avoid the above situation, the following settings are
recommended.
• For setup menu item 652, chose a line that is different
from the lines chosen for setup menu items 601 and
602.
•Do not use setup menu item 723 (page 12-24) to
blank the line chosen for setup menu item 652.
To set Stored Ownership
If you wish to set Stored Ownership (data in the
Source Pack which indicates “who”) when generating
a UMID, call up item 029 STORED OWNERSHIP in
the setup menu and proceed as follows.
See Section 12-2 “Setup Menu Operations” (page 12-2) for
more information about basic setup menu operations.
1 Set setup menu item 029 to “on” and press the F5
(SET) button.
The Stored Ownership setting screen appears. (The
following figure shows the monitor screen.)
