Tape management information
This unit automatically stores as the tape management information both the frame rate information which
indicates the shooting speed and the active frame information which indicates the first frame where the frame
image was switched in the user bits of the sub-code track area (this used to be the LTC area). This information
is output from the TC OUT connector, HD SDI MON connector and HD SDI EE connector. Further, the active
frame information is stored in the least significant digit of the user bits while the frame rate information is stored
in its lower third and fourth digits.
