Ancillary Data

This unit can play and record ancillary data multiplexed
into HDSDI signals. It can also input and output ancillary
data in MXF files when transferring files via FAM or FTP
connections. Transferable auxiliary data includes text data
(captions and metadata) and control signals.
Ancillary data in HDSDI/SDSDI
signals
This unit can record and play back closed captions
conforming to the EIA-708-B
1)
B standard, and text data conforming to the ARIB TR
2)
B-23 standard which comprise the VANC (Vertical
ancillary data) packets.
1) EIA: Electronic Industries Alliance
2) ARIB: Association of Radio Industries and Businesses
To record ancillary data
In maintenance menu item M3B: VANC RX
PARAMETER, set the lines where ancillary data is
inserted, the DID (Data Identifier word), and the SDID
(Secondary Data Identifier word) (see page 147).
To record and playback EIA-708-B standard
closed caption data in HDSDI signals
Set the following items.
• Sub items of maintenance menu item M3B0: VANC RX
PACKET
- LINE (line for the VANC to be received): 9LINE
(example)
- DID (data identification word): 61h
- SDID (secondary data identification word): 01h
To record EIA-608-B standard closed caption
data in HDSDI signals
Set the following items.
• Sub items of maintenance menu item M3B0: VANC RX

- LINE (line for the VANC to be received): 9LINE
(example)
- DID (data identification word): 61h
- SDID (secondary data identification word): 02h
To record EIA-608-B standard closed caption
data in SDSDI line 21 signals after conversion to
the EIA-708-B standard
Set the following items.

VANC packets
• The Japanese ARIB TR-B23 standard limits the number
of packets that can be multiplexed into HDSDI to 4
packets per line.
• The number of VANC packets that can be recorded that
is set using maintenance menu item M3B is limited to 9
packets per frame for 50P or 59.94P mode and 18
packets per frame for other modes.
• When VANC packets are not continuous from word 0,
and there is unused area on the line, then information
about the packet position is not recorded. Packets are
output flush left.
• During input, if a parity error is detected in a VANC
packet, the packet is discarded and recorded flush left.

Ancillary data in MXF files

VANC ancillary data recorded from a HDSDI signal can
be inserted to an MXF file as an ANC Frame Element
(conforming to the SMPTE436M-2006) and can be output.
This data can also be input and recorded on the disc.
To insert ancillary data into MXF files to
output
In setup menu item 666 METADATA ITEM OUT, select
"on" (see page 135).
HANC/VANC packets
Detection of HANC/VANC packets
HANC/VANC packets are recorded on the disc only when
the DATA ITEM of the head frame is identified as ANC
Frame Elements conforming to the SMPTE436M-2006
when an MXF file is input.

General MXF metadata

This unit examines the data contained in the header
1)
metadata area when an MXF file is input. If the data is
identified as the data created by the device other than
XDCAM at this time, one file (KLVE file) is created.
1) The header metadata area contains the metadata information about the
entire file. See SMPTE377M for details.
For details, see "Directory structure" (page 103) and
"Clip directory" (page 105).
