AJ-VNC150P Encoder/Decoder Board for DVCPRO HD Bank Data
This optional board is installed in the AJ-HD150P digital HD video cassette recorder to enable V-ANC (Vertical Ancillary) data to be record-
ed in the VAUX (Video Auxiliary Data) area of the DVCPRO HD format and played back.
Recording operation
1.

in the following range in the HD-SDI Y stream.
L9 to L20, L571 to L583 for 1080i/59.94 Hz
L9 to L25 for 720p/59.94 Hz
<Note>
The H-ANC data packets are not detected.
2.
Record the V-ANC data packets in the VAUX area of the
DVCPRO HD format in sequence starting with the line that
comes first up to the capacity specified below.
1080i/59.94 Hz: 5760 words/frame
720p/59.94 Hz: 2880 words/frame

An input data packet which has been input after the rated
capacity has been reached is not recorded or played back.

The HD-SDI video signals are also recorded at the same time.
<Note>
It is not possible to record or edit the V-ANC data alone.
Playback operation
