Tape Management Information - Panasonic HDC27H Operating Instructions Manual

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."
