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 FTP/CIFS
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)
standard and EIA-608-
B
1)
standard, and text data conforming to the ARIB TR
B-23
2)
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, set the lines where ancillary data is
inserted, the DID (Data Identifier word), and the SDID
(Secondary Data Identifier word).
For details, refer to the Maintenance Manual.
To record and playback EIA-708-B standard
closed caption data in HDSDI signals
Set maintenance menu items.
For details, refer to the Maintenance Manual.
To record EIA-608-B standard closed caption
data in HDSDI signals

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
depending on the relevant maintenance menu settings 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 an HDSDI signal is
inserted to an MXF file as an ANC Frame Element
(conforming to the SMPTE436M-2006). This data can
also be recorded on the SxS memory card from an MXF
file that has been input via CIFS/FTP.
HANC/VANC packets
Detection of HANC/VANC packets
When an MXF file has been input, HANC/VANC packets
are recorded on the SxS memory card if the DATA ITEM
of the head frame is identified as ANC Frame Elements
conforming to the SMPTE436M-2006.
