Major Differences among HDV1080i, DVCAM, and DV Formats
(This unit and other equipment for professional use may be functionally extended. For details, see the notes below the table.)

1)The unit cannot record
2)There are two modes for audio signal recording: Lock mode and Unlock mode. In Lock mode, the sampling frequencies of audio and video are synchronized. In Unlock mode, adopted by the consumer DV format, the two sampling frequencies are independent. Lock mode maintains high compatibility with higher formats and offers better digital processing and smoother transition than Unlock mode when you edit audio.
3)The unit cannot record in DV format with 16 bit: 32 kHz or 44.1 kHz.
4)The unit has been functionally extended with a function for switching between Lock mode and Unlock mode.
5)The unit has been functionally extended with a function to enable selecting DF/NDF and user bits setting for 60i (including 24p and 30p) with HDV or DV (SP) format.
