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.

Recorded frame number count

This indicates the number of frames recorded.

When the frame rate has been set to 24 fps and recording has been performed for 10 seconds, “0240” will be displayed as the count. When recording is started, the count is reset to “0000,” and the number of recorded frames per cut is counted up to “9999.”
