digits of the user bits.  The count is reset to zero
each time recording starts, and the count is
incremented with each active frame.
The active frame information is output to the lowest
digit of the user bits while the frame rate information
is output to the third and fourth lower digits.

In order for the time code that matches the
playback time code, which is output from the HD
SDI MON connector, to be output from the TC OUT
connector, set the MONITOR OUT switch to
“EE/PB,” and select “TCG/TCR” as the TC OUT
item setting on the TC/UB screen.
