Internal Dubbing
This unit has a function that dubs data from the Betacam/
Betacam SP/Betacam SX tape to the hard disk drive and
from the hard disk drive to the Betacam SX tape. For
dubbing from the Betacam SX tape to the hard disk drive,
the SDDI format data during tape playback is directly
transmitted to the recording system of the hard disk drive.
As a result, in the DNW-A100/A100P, high-speed dubbing
can be obtained.
The dubbing operation from the hard disk drive to the
Betacam SX tape can also be obtained by internally
connecting the data read from the hard disk drive and
processing as an input signal. This enables the result of
nonlinear editing using a hard disk to be recorded on the
tape. (Refer to Fig. A-4-4.)
