Page 389 A-4. Signal Processing 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 SDTI format data during tape playback is directly transmitted to the recording system of the hard disk drive.
