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.

1Set setup menu item 029 to “on” and press the F5 (SET) button.
