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. Example of display LTC user bits OWhen the internal color bar signals are being recorded User bits setting Frame frequency 5: 59.94 Hz 6: 60.00 Hz 01:12:01:50 Tape management information OActive frame information OREC START/STOP mark OWhen the camera's video signals are being recorded 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." Frame rate information 24 fps (23.98 fps) Frame frequency 5: 59.94 Hz 6: 60.00 Hz 02:40:24:50 Tape management information OActive frame information OREC START/STOP mark VITC user bits User bits setting Tape management information LTC user bits verification information 01:12:01:xx To verify the VITC user bits, set the DISPLAY switch to UB, and hold down the HOLD button. While the HOLD button is held down, the VITC user bits information appears on the counter display. The table below shows the correlation between the active frame rate and time code in the 24P, 25P, 30P and 50P modes.
